| | The '''Worked Example Authoring Tool (WEAT)''' is an innovative tool designed to facilitate the creation of worked examples for programming education through a ''human-AI collaboration'' approach. By integrating ChatGPT, WEAT assists instructors in generating line-by-line explanations for code examples in Java and Python. Instructors can provide the code and problem statement, and WEAT uses ChatGPT to generate explanations for each line of code. These explanations can then be reviewed, edited, and added into the worked examples, streamlining the process of creating educational programming materials. | | The '''Worked Example Authoring Tool (WEAT)''' is an innovative tool designed to facilitate the creation of worked examples for programming education through a ''human-AI collaboration'' approach.

| − | Explanations for important lines of code can be generated using the ''gpt-3.5-turbo'' model. Clicking on the "'''Generate Explanations'''" button will generate explanations using the default prompt. Newly generated explanations will be appended to the line and are distinguished with orange border color (check Figure 7).
| |
| − | | |
| − | Next to the "'''Generate Explanations'''" button, there is the [[File:weat_image9.png|48x40px]]history and [[File:weat_image6.png|44x40px]] custom prompt toggle buttons. Clicking on the [[File:weat_image9.png|48x40px]] button will show the previously generated explanations (check Figure 7) for this source. While clicking on the [[File:weat_image6.png|44x40px]] provide the ability to customize the ChatGPT prompt (check Figure 7).
| |
| − | | |
| − | As described in the user interface, these explanations can be dragged by the bars into the Annotations panel to be used/added to the currently selected line (check Figure 8). By default, previously generated explanations for the currently selected line are shown; click the "'''show all lines'''" to show all generated explanations. In the history panel click on another date/time to load explanations specific to that generation session.

| − | In the Annotations panel, explanations can be dragged by the bars. Drag and drop an explanation on another explanation to change their order, or hold "'''alt'''" key while dropping to append/merge them together, or drop the explanation on to the red trash can area to remove it (you will be asked to confirm this action since it is irreversible).
