Instructor Usage Guide

This guide is for instructors (group administrators) who use Exercode in their classes. It explains, in order of tasks, how to check students' progress and AI chat usage, and how to use that information for in-class support and post-class review.

1. Glossary

1-1. Permission types

Exercode has four types of permissions.

Name	Permission	Intended for
Setup administrator	Organization administrator	Overall manager for the school. Invites users to the organization and creates groups
Instructor	Group administrator	Class or subject teachers and TAs. The reader of this guide
Material author	Member of the material repository	People who create and maintain materials in the GitHub material repository
Student	General member	Students taking the class

Instructors can view information about the students in groups they manage and the courses added to those groups.

In this guide, learners are called "students." On screen, they may appear as "学生 (students)," "学習者 (learners)," or "受講者 (attendees)," but all mean the same thing.

1-2. Organizations and groups

Term	Meaning	Example
Organization	An educational institution such as a school or university	〇〇大学, 〇〇専門学校
Group	A class or department within an organization. Instructors check the students in the groups they teach	〇〇学科 1 年（2026 年度）
Member	A user belonging to an organization or group (both instructors and students)

An organization contains multiple groups. Conceptually, it looks like this:

• Organization (〇〇大学)
  • Group (〇〇学科 1 年 A 組)
    • Member (instructor)
    • Member (student A)
    • Member (student B)
  • Group (〇〇学科 1 年 B 組)
    • Member (instructor)
    • Member (student C)
    • Member (student D)

1-3. Material structure

Term	Meaning	Example
Course	A collection of materials for the whole subject. Corresponds to one subject in a class	Python 言語の基礎, Java 演習
Lecture	A unit that makes up a course. Corresponds to one class session	第 1 回 変数と型
Material	The smallest unit of teaching material. Includes explanatory text, problems, and submission settings	演習 1-1

For example, a course "Python 言語の基礎" run over 15 lectures is registered in Exercode as follows. Each lecture contains the materials to be solved in that session.

• Course: Python 言語の基礎
  • Lecture: 第 1 回 変数と型
    • Material: 演習 1-1 変数の宣言
    • Material: 演習 1-2 型の変換
  • Lecture: 第 2 回 条件分岐
    • Material: 演習 2-1 if 文
    • Material: 演習 2-2 比較演算子
  • … (continues through lecture 15)

To make this course available to students, add the course to a group. For example, if you add "Python 言語の基礎" to the group "情報工学科 1 年 A 組," it will appear in the 科目一覧 (course list) of students in that group. Students open the materials that match each lecture and solve the problems. Submission periods and similar settings are configured per material (see 5-3).

2. What each permission can do

For details on permissions, see Permission types and capabilities.

3. Overall flow

The steps for an instructor to use Exercode in class are the following eight. After joining the organization (step 2) and preparing courses and students (steps 4–6), proceed to checking progress during and after class (steps 7 and 8).

Step	Task	Who does it	Description
1	Invite instructors to the organization	Setup administrator	2. Create groups and register instructors in the setup guide for setup administrators
2	Join the organization from the invitation email	Instructor	4-1. Join the organization from the invitation email
3	Make the instructor a group administrator	Setup administrator, or another group administrator	4-2. Confirm you are a group administrator
4	Add courses to groups and configure materials	Instructor (or setup administrator)	5. Prepare materials
5	Invite students to the organization	Setup administrator	5. Register students in the setup guide for setup administrators
6	Add students to groups	Instructor (or setup administrator)	6-1. Add students to a group
7	Check student status during class	Instructor	7. Check student progress during class
8	Review and grade after class	Instructor	8. Review after class, 9. Grade manually

• Steps 1, 3, and 5 are performed by the setup administrator (step 3 may also be done by another group administrator). Instructors only need to confirm in 4-2. Confirm you are a group administrator that it is set up. If students have not joined the organization, ask the setup administrator to send invitations.
• Steps 4 and 6 may already have been completed by the setup administrator. You can check whether they are done in 4-3. Check that class preparation is complete; if they are, you can skip them. Discuss with the setup administrator to decide how much of this the instructor will handle.

4. First steps

4-1. Join the organization from the invitation email

Who can do this: Instructor

When the setup administrator invites you as an instructor, an invitation email arrives from no-reply@willbooster.dev.

1. Open the invitation email and go to the URL written in it.

   

2. In the "Create account / sign in with email address" field, enter the email address that received the invitation and press 確認コードを送信 (Send verification code).

   

3. An email containing a verification code arrives. Enter the code and press 確認してログイン (Verify and sign in).

   

4. When "組織「○○○（組織名）」に参加しますか？" (Do you want to join the organization "○○○ (organization name)"?) is displayed, press 参加 (Join).

   

If the invitation email does not arrive: Check your spam folder. If you cannot find it, tell the setup administrator your email address and ask them to resend the invitation.

Signing in from the second time onward: Press アカウント作成／ログイン at the upper right of the Exercode top page, enter the email address that received the invitation, and sign in with the verification code sent to it. Joining the organization is only needed the first time.

Tip: To skip entering a verification code every time you sign in, register a passkey. Press the account button at the upper right → 設定 (Settings), then press パスキーを追加 under パスキー (Passkeys) and register using your browser or device authentication. From then on, you can sign in with パスキーでログイン (Sign in with passkey) on the sign-in screen.

4-2. Confirm you are a group administrator

Who can do this: The setup administrator or another group administrator of the group (there is no action required on the instructor's side)

Features introduced later in this guide, such as checking progress during class (chapter 7), reviewing after class (chapter 8), and manual grading (chapter 9), can only be used by group administrators of the groups you teach. You can confirm whether this is already set up in either of the following ways.

Check in the group list (you can check even if no course has been added to the group yet)

1. Press 所属 (Affiliations) at the top of the screen and open the organization name.
2. If グループ (Groups) appears and the opened list contains the group you teach, it is set up. If グループ does not appear, you are not yet a group administrator.

Check on the course page (if a course you teach has been added to the group)

1. Open 科目一覧 (Course list) at the top of the screen.
2. Open the course you teach.
3. If グループ管理者向けメニュー (Group administrator menu) is displayed, it is set up.

If you cannot confirm either way: Ask the setup administrator to check the following three points:

• Whether you have already joined the organization
• Whether you are a group administrator of the group you teach
• Whether the course has been added to that group (courses only added to the organization will not be displayed)

4-3. Check that class preparation is complete

Before the first class, check the following. For anything not yet done, proceed in consultation with the setup administrator.

What to check	Where to check	If the instructor handles it
The course you teach is added to your group	A course appears in 科目一覧, and opening it shows グループ管理者向けメニュー	5-1. Add a course to a group
Students are added to the group	所属 → organization name → グループ → target group → メンバー (Members)	6-1. Add students to a group
Material release timing and deadlines match the class schedule	科目一覧 → target course → 編集 (Edit) for the target material	5-3. Set material release timing and deadlines
(Optional) Lecture schedule is set	科目一覧 → target course → 授業時間設定 (Lecture schedule settings)	5-4. Set the lecture schedule
(Optional) For materials used for in-class surveys, real-time surveys are enabled	科目一覧 → target course → 編集 for the target material → リアルタイムアンケート (Real-time survey) under the 提出・試験設定 (Submission & exam settings) tab	"Preparation (before class)" in 7-5. Run a real-time survey

5. Prepare materials

Prepare the materials to use in class. Materials are inside a course, so first add the course to your group (5-1 and 5-2), then set the material release timing and deadlines to match your schedule (5-3 and 5-4), and finally review the content in the same view as students (5-5). If the setup administrator has already added the course, start from 5-3.

5-1. Add a course to a group

Who can do this: Instructor (group administrator), setup administrator (organization administrator)

Add a course created in the organization, or a course imported from a material repository registered to the organization, to your group. Not needed if the setup administrator has already added it (i.e., the course you teach appears in 科目一覧).

1. Press 所属 at the top of the screen and open the organization name.

   

2. Open グループ and then open the target group.

3. Open 科目 (Courses).

4. Enter the ID of the course you want to add. Courses not yet added to a group do not appear in the instructor's 科目一覧, so ask the setup administrator for the course ID (it is the part after /courses/ in the course page URL).

5. Press 追加 (Add).

   

Added courses can only be used by members of that group.

If you cannot add the course: You can only add courses created within your organization and courses imported from a material repository registered to your organization. Courses shared from other organizations, for example, will produce an error, so consult the setup administrator. If you enter a non-existent ID, no error is shown and it is simply ignored. After pressing 追加, check that the course appears in 科目一覧.

5-2. Create a new course

Who can do this: Instructor (group administrator), setup administrator (organization administrator)

If you teach with your own materials, you can create a course on the Exercode screen and write the materials directly.

1. Open 所属 → organization name → グループ → target group → 科目.
2. Press 科目の作成 (Create course).
3. Enter 科目名 (Course name) and 説明 (Description).
4. Under グループ (Group), select a group you manage.
5. Press 作成 (Create).

Created courses can only be used by members of the selected group. After creation, you are taken to the course edit screen, where you can add lectures with 授業を追加 and materials with 教材を追加. To write material text and questions, press Markdownを編集 for the material on the course edit screen and create them on the 本文・設問 (Text & questions) tab. For detailed steps on creating and editing courses, see Create a course for an organization or group; for editing materials, see Edit materials.

Caution: If you delete a lecture or material on the course edit screen after students have started submitting, all of those students' submissions and progress for that lecture or material will also be deleted, and this cannot be undone. Deleting an existing question on the material edit screen also breaks its link to submission history. After operation begins, do not delete lectures, materials, or questions. For materials you are not using, either set the submission release to a later date so students cannot see them, or rewrite their text.

5-3. Set material release timing and deadlines

Who can do this: Instructor (group administrator), setup administrator (organization administrator), material author

1. Open 科目一覧 → target course.
2. Press 編集 (Edit) for the target material.
3. On the 提出・試験設定 (Submission & exam settings) tab, configure the items in the table below and press 更新 (Update).

Item	Description
Submission opening	The date and time students can start submitting. Before this time, the material content is not referenced by students' AI chat
Submission deadline	Submissions after this time are treated as late submissions and shown in yellow in learning analytics
Final submission deadline	After this time, submissions are no longer accepted
Exam mode	A setting for quizzes and exams. Students cannot use learning support features such as AI chat, and hints are not shown during the submission period
Early exam termination	Can only be set in exam mode. If you check 途中で試験を終了できるようにする (Allow ending the exam early), students can end the exam before the final submission deadline
Mock exam mode	Switches to a screen for practicing exams. Correctness and accuracy rate are shown to students after the final submission deadline. AI chat works as usual

• Items that are not set impose no restriction. If submission opening, submission deadline, and final submission deadline are all left blank, students can submit at any time.
• To have students use a material for each class, set the submission opening to match the class schedule.
• These settings apply per material. If the same course is used across multiple groups or organizations, changes apply to all students using that material.
• About early exam termination:
  • Students who end the exam cannot answer or submit until the deadline. Ending cannot be undone.
  • If no final submission deadline is set, the end button is not shown.
• In mock exam mode, questions are answered in a 問題一覧 (Problem list) view and a one-question-at-a-time view. Coding problems are not shown in 問題一覧.

Caution: Materials imported from a GitHub material repository may be overwritten by changes made on the 編集 screen when re-imported. For settings you want to keep, ask the material author to reflect them in the material repository. Settings to disable AI chat or hints per material, or the time until hints become available, are configured by the material author in the material repository. The settings available are summarized in "3. Add materials" of the setup guide for setup administrators. Courses created on the Exercode screen (5-2) have no material repository, so these settings cannot be made; the only way to stop students' AI chat is exam mode.

5-4. Set the lecture schedule

Who can do this: Instructor (group administrator), setup administrator (organization administrator), material author

Setting the lecture schedule lets learning analytics distinguish submissions made during class hours from those made outside class hours.

1. Open 科目一覧 and open the target course.

   

2. Press 授業時間設定 (Lecture schedule settings).

   

3. Enter the day of the week, start time, and end time, and press 時間を追加 (Add time). For classes with different days or time slots, you can add more.

   

4. Confirm the entry has been added under 現在の授業時間 (Current lecture schedule), and press 変更を保存 (Save changes).

   

Caution: The lecture schedule is one per course. If the same course is used by multiple groups, changes are reflected in the learning analytics of all groups using that course. Instructors can only set schedules for courses already added to their own groups.

5-5. Review materials in the same view as students

Who can do this: Instructor (group administrator), setup administrator (organization administrator), material author

Materials on the course page can be opened in two ways.

Button	How it opens
始める (教員モード) (Start (teacher mode))	Lets you open and review the material even outside the submission period
始める (学生モード) (Start (student mode))	Opens the material under the same conditions as students

• Materials whose submission opens more than 10 minutes from now cannot be opened with 始める (学生モード). Open them with 始める (教員モード).
• Instructors can use the AI chat on the material screen and problem screen even for materials where students cannot use the AI chat (exam-mode materials, materials with AI chat disabled, and materials before submission opening). You can try how the AI answers students' questions before class.

6. Manage students and instructors

Register the students and instructors who belong to your group. This includes adding and removing students (6-1 and 6-2), granting or revoking management permissions for other instructors and TAs (6-3 and 6-4), and registering students' names and student IDs (6-5). If the setup administrator has already added students, 6-1 and 6-2 are unnecessary. Use this when students or instructors are added or removed during the course.

Adding and removing members and changing permissions are all done on the group's メンバー (Members) screen. To open it:

1. Press 所属 at the top of the screen and open the organization name.

   

2. Open グループ and then open the target group.

3. Open メンバー.

   

Important premise: Only people who have already joined the organization can be added to a group. Only the organization administrator (setup administrator) can invite people to the organization. If someone has not joined the organization, ask the setup administrator to send an invitation.

6-1. Add students to a group

Who can do this: Instructor (group administrator), setup administrator (organization administrator)

1. Open the group's メンバー screen.
2. Enter the email addresses of the students you want to add. You can enter multiple addresses separated by line breaks or spaces.
3. Do not check 管理権限 (Management permission).
4. Press 追加・権限の更新 (Add / update permissions).

Caution: The 管理権限 checkbox applies equally to all email addresses entered. If you enter an instructor's email address together with students' addresses, that instructor's group administrator permission will be removed.

6-2. Remove students from a group

Who can do this: Instructor (group administrator), setup administrator (organization administrator)

1. Open the group's メンバー screen.
2. Enter the email addresses of the students you want to remove.
3. Check the number of people to be deleted shown on the screen (e.g., 現在の入力では 2 人が削除されます。) and press 一括削除 (Bulk delete).
4. On the confirmation screen, check the number to be deleted and press はい (Yes).

Removing them from the group does not remove them from the organization.

6-3. Make another instructor or TA a group administrator

Who can do this: Instructor (group administrator), setup administrator (organization administrator)

If several instructors or TAs teach the same group, you can make others group administrators. You do not need to ask the setup administrator.

1. Open the group's メンバー screen.

2. Enter the email address of the person you want to make a group administrator.

   

3. Check 管理権限 (Management permission).

   

4. Press 追加・権限の更新 (Add / update permissions).

5. Confirm the checkmark appears in the 管理権限 column of the member list.

If they do not appear in the list: The person may not have joined the organization. Email addresses of people who have not joined are ignored without showing an error. Ask the setup administrator to send an invitation to the organization.

6-4. Remove a group administrator's permission

Who can do this: Instructor (group administrator), setup administrator (organization administrator)

Permissions of instructors or TAs who are no longer teaching can be removed while keeping them in the group.

1. Open the group's メンバー screen.
2. Enter the email address of the person whose permission you want to remove.
3. Uncheck 管理権限.
4. Press 追加・権限の更新 (Add / update permissions).
5. Confirm the checkmark in the 管理権限 column of the member list has been removed.

• You can remove your own permission, but once removed, you cannot restore it yourself. You will no longer be able to manage this group, and restoring it requires asking another group administrator or the setup administrator. Be careful not to enter your own email address when adding students.
• If you also hold organization administrator permission, removing your group administrator permission still lets you manage the group as an organization administrator.

6-5. Register student profiles

Who can do this: Instructor (only members of your own groups), setup administrator (organization administrator)

Registering students' names and student IDs via CSV makes them easier to identify in learning analytics, as their names appear in the name column. Students without a registered profile show - in the name column.

Caution: Profiles are overwritten by the contents of the CSV saved last. Blank fields will erase existing values. If the setup administrator and an instructor register using different CSVs, previously registered content may be lost. Decide with the setup administrator who will do this.

1. Open 科目一覧 → target course, and press ユーザプロフィール (User profiles) in the グループ管理者向けメニュー (Group administrator menu).
2. Press テンプレートをダウンロード (Download template) and save the CSV template.
3. From row 2 onward in the template, enter information for each student.
   • Do not change the column names in row 1 (メールアドレス, 氏名, 所属, 学籍番号, 入学年度, 学部, 学科, クラス).
   • Only メールアドレス (email address) is required.
   • Enter only numbers for 入学年度 (year of enrollment).
4. Upload the CSV you entered in the CSVファイル field, and check the contents loaded in the table on screen.
5. Press 保存 (Save). If 更新しました。 (Updated.) is shown, it has been saved.
6. On the group's メンバー screen, confirm the profile has been reflected.

If it is not reflected: The following rows are not reflected, and no notice is shown.

• Rows for people who have not joined the organization
• Rows for people who are not in groups you manage

Also, for columns whose names have been changed or deleted, the registered values are erased.

6-6. Guidance to students and handling inquiries

Students are informed in the Student usage guide as follows. Use this as a reference when students ask questions.

• AI chat content and hint usage counts can be checked by the instructor to improve classes
• Students' AI chat does not reference materials for which AI chat is disabled by the instructor, or the content of exam materials
• After the submission period ends, model answers are shown. Depending on the instructor's settings, some problems will not display them
• If the invitation email does not arrive, students should report it to their instructor

If a student reports that the invitation email has not arrived, check the student's email address and tell the setup administrator. Resending invitations is done by the setup administrator (organization administrator).

7. Check student progress during class

Who can do this: Instructor (group administrator), setup administrator (organization administrator)

During class, keep the learning analytics screen open to check students' status. The screen is explained in this order: how to read the progress table colors (7-1), how to find students to talk to (7-2 and 7-3), and the status of questions to the AI (7-4). For running an in-class survey, see 7-5.

When class starts

1. Open 科目一覧 → target course → 学習分析 (Learning analytics). The 進捗 (Progress) tab is displayed.

   

2. Under 表示授業 (Displayed lectures), select today's class. To view previous sessions' progress alongside, increase the number under 前後授業数 (Number of surrounding lectures). If you teach multiple groups, use ユーザを絞り込む (Filter users) to display only today's group.

3. Turn on the 自動更新（約1分ごと） (Auto-refresh, about every minute) switch. The display refreshes approximately every minute.

   

4. If projecting on a classroom screen, check 学生を匿名化 (Anonymize students). The columns for students' names and email addresses will no longer be shown.

What to check on the 進捗 tab

Where to look	What you learn	Description
苦戦中のメンバー (Struggling members, center of screen)	Students who may need to be spoken to, and the reasons	7-2
Progress table for 全てのメンバー (All members, bottom of screen)	Which problem each student has answered correctly up to	7-1, 7-3
Speech bubbles in the AIチャット column	Students currently asking the AI, and trends in their questions	7-4

Speak to students who are individually stuck. If many students are stuck on the same problem or asking the AI the same thing, provide supplementary explanation to the whole class.

• The settings for ユーザを絞り込む, 学生を匿名化, and 表示授業 are shared between the 進捗 tab and the つまずき分析 tab.
• The selected tab and lecture are included in the URL, so you can share or bookmark them as they are.

7-1. How to read progress colors

Color	Meaning
Green	Correct
Yellow	Correct after the deadline
Red	Incorrect
Light green	Correct during review
Gray	Not started

"Review" is a feature, for materials other than exam mode, that lets students re-solve multiple-choice and free-response questions while viewing hints after the final submission deadline (or after submitting all questions, even before the deadline). Correct answers during review do not affect grades, so they are colored differently from correct answers before the deadline.

Clicking a cell opens the list of that student's submissions to that problem, where you can view the submitted code.

If a lecture schedule is set, the display changes depending on when the submission was made.

Display	Meaning
Filled cell	Submitted during lecture hours (worked on during class)
Outline only	Submitted outside lecture hours (worked on during self-study or homework)

7-2. Struggling members

Displays students who may need to be spoken to, along with the reason. Up to 10 students not yet addressed are shown; students you have marked as addressed are displayed in full after them. If a student has multiple reasons, they are combined into one row, and 状況 (Status) shows the basis.

Reason	Display condition
Long stall	Working on a problem not yet answered correctly, right now (within 5 minutes of the last operation). Time spent on that problem is shown in 状況
Repeated errors	3 or more consecutive incorrect answers on the same problem within the last 15 minutes
Requesting answers	3 or more questions to the AI asking for answers or code within the last 15 minutes
Not started	Has neither viewed nor submitted the problems of the displayed lecture (shown at the bottom of the list, since they may be absent)

For a student you have spoken to, check the box at the start of the row, and they will be shown faintly at the end of the list as addressed.

• The check is cleared when the date changes.
• If a new reason is added after checking, the check is cleared and they return to the prominent display.

7-3. Status per student

In the list of all students, you can check the following columns about the coding problem each student last opened.

Column	Content
Last opened problem	The last problem the student opened
Last activity	学習中 (Studying) if within 5 minutes of the last operation, or the time elapsed since the last operation
Status	Whether the student has ever answered that problem correctly (正解, 不正解, 未提出). Once correct, it stays 正解 even if they later answer incorrectly
Total time on page	The total time spent with that problem open
Hint count	The number of times additional hints were generated for that problem. Displaying error locations alone does not increase it
Submission count	The number of submissions for that problem. Clicking it opens the submission list filtered to that student and problem

Students with many ヒント回数 (hints) or 提出回数 (submissions) but still 不正解 (incorrect) in 状態, or with a long 総滞在時間 (total time), may be stuck.

7-4. Status of AI chat questions

A speech bubble in the AIチャット column indicates that the student has asked the AI questions in this course.

Display	Meaning
Green filled bubble	Last question within 5 minutes
Gray outlined bubble	Last question more than 5 minutes ago
Number next to bubble	Number of conversations today
答え要求 with a count	Within the last 15 minutes, there are questions asking for answers or code
エラー相談 (Error consultation)	Within the last 15 minutes, no questions asking for answers or code, but there are questions about errors

Clicking a bubble lets you view an overview and the content of today's questions. Clicking 過去の会話を見る (View past conversations) opens the AIチャット tab filtered to that student.

7-5. Run a real-time survey

Who can do this: Instructor (group administrator), setup administrator (organization administrator), material author

During class, you can run a survey on the spot using a material's questions and show the aggregated results to students.

Preparation (before class)

1. Open 科目一覧 → target course → 編集 for the material to use for the survey.
2. Check リアルタイムアンケート (Real-time survey) under the 提出・試験設定 tab and press 更新. All questions in the material become available to run as a survey.
3. For questions with no correct answer (such as questions asking for opinions or impressions), check リアルタイムアンケートとして扱う (Treat as real-time survey) on the question. Every answer is recorded as correct.

During the survey (in class)

1. Ask students to keep the target material screen open. Students who do not have the material screen open will not see the survey.
2. On the course page, press アンケート管理 (Survey management) for the target material.
3. Under 現在接続中の受講者 (Currently connected attendees), check the number of students with the material screen open (参加者数, participant count).
4. Press アンケート開始 (Start survey) on the question to run. The answer screen appears on students' material screens.
5. When enough answers have been collected, press アンケート終了 (End survey).
6. To show results to students, press 結果を公開 (Publish results). A chart of the aggregated results appears on students' screens. You can revert to unpublished with 結果公開を停止 (Stop publishing results).

Caution: Pressing 開始前に戻す (Return to before start) deletes all students' answers for that question without a confirmation dialog. Do not press it if you want to keep the results.

• Pressing アンケート開始 ends any other question in the same material that is running a survey.
• An ended question cannot be restarted until you press 開始前に戻す.
• Only aggregated results are shown to students; for free-text questions, only the number of answers is shown.
• Answers are recorded per student; on the アンケート管理 screen, participants' display names (or "名前なし" (No name) if not set) and email addresses are shown. Be careful when projecting this on a classroom screen.
• In materials that use real-time surveys, review is not available.
• When an instructor opens a material with 始める (学生モード), the answer screen appears just as for students, and they are counted as participants. To check results, open it with 始める (教員モード).

8. Review after class

Who can do this: Instructor (group administrator), setup administrator (organization administrator)

After class, review what students got stuck on using the つまずき分析 (Stumble analysis) and AIチャット tabs in learning analytics.

8-1. Check trends in questions with stumble analysis

1. Open 学習分析 for the course and select the つまずき分析 tab.

   

2. Select the lecture to review under 表示授業.

   

3. Press 分析する (Analyze), and the AI groups the questions by topic.

   

4. Press a topic under 質問の多かったトピック (Most-asked topics) to view:

   • What was not understood
   • Hints for the material (AI estimates)
   • Students' statements (pressing 会話を開く (Open conversation) opens the details of that conversation)

   

• The top of the screen shows the number of students who asked questions, the number of questions, the percentage of questions requesting answers or code, and the materials with the most questions.
• Analysis results are saved and displayed the next time. If more questions are added after analysis, they are counted as 未分析 (Not analyzed), so press 再分析 (Re-analyze) as needed. If students whose questions were analyzed fall outside the filter range or conversations are deleted, the previous results are not displayed and you are prompted to 再分析.
• If fewer than 3 students asked questions, analysis is not performed and only the per-student list is shown.
• 学習者別 (By learner) shows each student's number of questions, questions requesting answers or code, submissions, and correct answers. Pressing a student shows their chronological history of questions and submissions for that lecture.
• CSVダウンロード lets you save the 質問の多かったトピック table. Students' statements, names, and email addresses are not included.
• When having the AI analyze, students' names and email addresses are not passed to it.

8-2. Review AI chat conversations

The AIチャット tab in learning analytics lists conversations between students and the AI, and lets you review each conversation in full.

1. Specify the lecture, material, student, group, question date, and keywords in question text, then press 絞り込む (Filter).

   

2. Select the question of the conversation you want to review from the list. All messages in the conversation are shown in chronological order. Operations where the AI referenced the material can be checked by expanding AIの操作 (AI operations).

3. Use 前のチャット (Previous chat) and 次のチャット (Next chat) to move to adjacent conversations, and チャット一覧に戻る (Back to chat list) to return to the list.

   

• Keywords search the text of students' questions. The text of AI responses is not searched.
• Conversations started from the course screen are not linked to a material and are shown as 教材未指定 (No material specified).

8-3. Check hint usage

Check the hints that students who used many hints were viewing.

1. In the 全てのメンバー table of learning analytics, press the 提出回数 (Submission count) of the student you want to check to open the submission list.

   

2. Open the submission you want to check.

3. Check 最後に閲覧したヒント情報 (Last viewed hint information) in the submission details.

   

8-4. Download progress as CSV

To save students' submission status as CSV for grade aggregation and similar uses:

1. Open 学習分析 for the course. The 進捗 tab is displayed.

2. Under ユーザを絞り込む and 表示授業, select the target students and lectures.

3. If needed, press the ▼ next to CSVダウンロード above 全てのメンバー, and choose 列 (Columns) and オプション (Options).

   

4. Press CSVダウンロード (Download CSV).

Selectable item	Content
列 (Columns)	By default includes ユーザID, メールアドレス, 名前, and 提出/正誤. You can add profile fields such as 所属 and 学籍番号, plus 提出日時 (submission date/time), 提出/ソフト締切前か (submitted before soft deadline), 提出/点数 (score), 提出/優秀作品か (outstanding work), and 提出/ソースコード（1ファイルのみ） (source code, single file only). The score, outstanding work, and source code columns are output only for coding problems
オプション (Options)	Selecting 平均点・標準偏差を計算する（河原式） (Calculate mean and standard deviation (Kawahara formula)) adds a score column that computes the percentage of TRUE among the output columns on a 100-point scale, along with rows for the mean and standard deviation excluding absent students (those whose score is 0), as formulas. Selecting 最後に提出が締め切られた教材のみ (Only materials whose final submission deadline has passed) outputs only the last one, among the displayed lecture range, of materials whose final submission deadline has passed

• The column names in row 1 of the CSV are output as English names such as user_id and email.
• Organization administrators and group administrators are not included in the CSV.

Caution: Even with 学生を匿名化 (Anonymize students) enabled, names and email addresses are output as-is in the CSV. Handle with care.

8-5. View submitted code on the leaderboard

Who can do this: Instructor (group administrator), setup administrator (organization administrator), material author

For problems where code readability review is enabled in the material repository, a リーダーボードを見る (View leaderboard) button appears on the problem screen. If this button is absent, it is not available for that problem. The material author decides whether to enable this in the material repository.

Instructors can view the submitted code and evaluations (such as ステップ数 (steps) and 残りの指摘数 (remaining findings)) for all students listed on the leaderboard, even before the deadline. Pressing コードを読む (Read code) opens that student's submitted code. The range visible to students differs from what instructors can see.

9. Grade manually

Who can do this: Instructor (group administrator), setup administrator (organization administrator)

Problems that cannot be graded automatically, such as reports (manually graded problems), are scored and given feedback on the submission details screen. Until graded, students see "手動採点の結果をお待ちください。" (Please wait for manual grading results.). Which problems are manually graded is set by the material author in the material repository and cannot be changed from the instructor's screen.

1. Open 学習分析 for the course. If there are submissions requiring manual grading, a notice "手動採点が必要な提出があります。" (There are submissions requiring manual grading.) appears at the top of the screen.

   

2. In the progress table, press a cell showing the pre-grading icon. Manually graded problems appear as wider cells.

   

3. From the opened submission list, open the submission you want to grade.

4. On the right side of the submission details screen, under 手動採点の結果 (Manual grading result), enter the 点数 (Score).

5. As needed, write comments in フィードバック (Feedback). For especially good submissions, check 優秀作品 (Outstanding work).

   

6. Press 保存 (Save). Once saved, the grading result appears in the student's submission details.

7. To move to the next submission to grade, use 次の提出に進む (Go to next submission), 同じユーザの次の提出に進む (Go to next submission by the same user), or 同じ問題の次の提出に進む (Go to next submission for the same problem). Use 学習分析に戻る (Back to learning analytics) to return to the learning analytics screen.

   

You can also operate with the keyboard.

Operation	Key
Move to the 点数 field	Ctrl (Cmd on Mac) + S
Move to the フィードバック field	Ctrl (Cmd on Mac) + E
Save	Ctrl (Cmd on Mac) + Enter

You can also add scores and feedback in the same fields for automatically graded problems.

10. Troubleshooting

Symptom	What to check
You are not receiving the invitation email	Check your spam folder (sender: no-reply@willbooster.dev). If you cannot find it, tell the setup administrator your email address and ask them to resend the invitation
グループ管理者向けメニュー or 学習分析 is not displayed on a course	Ask the setup administrator to confirm that you have joined the organization, are a group administrator of the group you teach, and that the course has been added to that group
A student says they did not receive the invitation email	Check the student's email address and tell the setup administrator. Resending the invitation is done by the organization administrator
A course does not appear in a student's 科目一覧	Check whether the student has been added to the group and whether the course has been added to that group
You cannot add a course to a group	Whether it is a course created within your organization or imported from a material repository registered to your organization. Consult the setup administrator for other courses
The AIチャット button does not appear for students	Check whether the material is in exam mode or the submission opening time has passed. If AI chat is disabled in the material repository, the material author should confirm
Students do not appear in learning analytics	Check whether the group the students belong to is selected in ユーザを絞り込む
A student's name shows as - in learning analytics	The student's profile (name) is not registered. See 6-5. Register student profiles, or ask the setup administrator whether it is registered
The profile CSV was saved but not reflected	Check whether the student is in a group you manage and whether the email address is correct. Rows that are out of scope are not reflected without notice
You cannot make another instructor a group administrator	Check whether the person has joined the organization. Email addresses of people who have not joined are ignored without an error
The AIチャット tab does not appear in learning analytics	Check whether you are a member of the organization and a group administrator of a group linked to the course
Few AI chat counts in learning analytics, or past questions are not visible	The counts in the progress tab and the bubble list only cover today's conversations. Check the AIチャット tab for past questions
ヒント回数 does not increase	ヒント回数 counts the number of times additional hints were generated. Displaying error locations alone does not increase it
A conversation is displayed as 教材未指定	AI chats started on the course screen are not linked to a material, so they show as 教材未指定
Changes made on the material 編集 screen revert	Materials imported from a GitHub material repository are overwritten on re-import. Ask the material author to reflect the changes in the material repository
A student says there is no 模範解答 tab or model answers are not shown	If the material repository is set not to show model answers, the tab itself is not shown. Even when set to show them, they are not displayed until after the final submission deadline. Ask the material author to check the setting
Grading results are not displayed (採点結果の表示は無効になっています。 (Display of grading results is disabled.) appears)	The material repository is set not to show grading results. Under this setting, grading results are not shown on the instructor's screen either. Ask the material author to check the setting
A student says they cannot copy and paste in the code editor	The material repository is set to prohibit copy and paste. Instructors can copy and paste. Ask the material author to check the setting
A real-time survey is not displayed to students	Check whether the students have the target material screen open, and whether they are shown in 現在接続中の受講者 under アンケート管理
