EDU Activity Editor

Activity Structure

Educational activities are organized into a hierarchical structure consisting of three levels:

This structure allows educators to create organized courses where students progress through lessons and receive hints when needed.

User Interface Overview

The editor is divided into two main sections:

Creating Activity Content

Add a Group

Groups organize lessons into categories. For example, a robotics course might include groups such as:

• Getting Started
• Robot Movement
• Sensors
• Artificial Intelligence

To create a group:

1. Click Add Group.
2. Enter a title for the group.
3. Add a description explaining the purpose of the group.
4. Optionally add an image representing the group.

Add a Lesson

Lessons contain the instructions students will follow when completing an activity.

1. Select a group.
2. Click Add Lesson.
3. Enter a lesson title.
4. Add a short description for quick previews.
5. Write the full lesson instructions using the HTML editor.

Lessons typically include explanations, images, and step-by-step instructions for students.

Add a Hint

Hints provide optional help to students who may be stuck.

1. Select a lesson.
2. Click Add Hint.
3. Enter a title.
4. Write hint instructions or guidance.

Students can reveal hints inside the ARC education app when needed.

Editing Lesson Content

The lesson description and hint content are edited using the built-in HTML editor. This editor allows you to format lesson instructions with rich content.

Formatting Tools

• Bold, italic, and underline text
• Bullet lists and numbered lists
• Headings (H1, H2)
• Links
• Insert images

Image Support

Images can be added to lessons in two ways:

• Insert images using the toolbar
• Paste images directly from the clipboard

Images can be resized by dragging the corner handles after selecting the image.

Managing Content

Duplicate Items

The duplicate feature allows you to quickly copy groups, lessons, or hints. The copied item will be inserted next to the original and assigned a new internal ID.

Reorder Items

Use the Move Up and Move Down buttons to change the order of groups, lessons, or hints. This determines the order students see them in the ARC education app.

Delete Items

The delete button removes the selected item from the activity. A confirmation prompt will appear before deletion.

Images

Groups, lessons, and hints can include an image to visually represent the content.

Supported formats include:

• PNG
• JPEG
• GIF
• BMP
• WebP

Images are embedded directly into the activity data so the lesson can be distributed as a single file.

Importing and Exporting Activities

Export JSON

The editor can export all activity content into a JSON file. This file can be used to back up files for offline editing and re-uploading, etc. Essentially, it exports all the data from the activity lessons.

1. Open the File menu.
2. Select Export JSON.
3. Save the file.

Import JSON

Previously created activities can be imported using the Import feature.

1. Open the File menu.
2. Select Import.
3. Select a JSON activity file.

Best Practices for Lesson Design

• Keep lesson instructions clear and detailed.
• Use images to demonstrate robot behavior or required Blockly blocks.
• Break large concepts into multiple lessons.
• Provide hints that guide students instead of giving direct answers.
• Organize lessons into logical groups for easier navigation.
