Implementing Exercises

Overview

Questions

• How should exercises be presented in a lesson website?

Objectives

After completing this episode, participants should be able to…

• Display exercises and their solutions in a lesson site.

Well-designed exercises are one of the most valuable resources for an instructor and any time spent on this is well invested.

Demo of Writing an Exercise

---

To create an exercise in The Carpentries Workbench, you can use colon-delimited sections called ‘fenced divs’. In fact, there are many types of boxes in the lesson infrastucture that use fenced divs. In the Workbench, exercises are divided into two categories: discussions (where the main task is for participants to discuss a topic or prompt) and challenges (where the main task is a problem to be solved).

To start a challenge fenced div the line must contain at least 3 colons, then the challenge tag. Then the content of the challenge is included on the following lines. Finally, you can close the fenced div using another line with least 3 colons.

If you also want to include an expandable solution box for the challenge you can add a solution fenced div within the challenge box. The format is the same as for a challenge except the tag is solution instead. Note the solutions can all be expanded for more accessible reading using the “Expand All Solutions” option at the top of each episode.

For readability, you may want to have the length of the closing lines match the opening lines. See in the above how the challenge and the nested solution’s closing lines are similar lengths to the their corresponding opening lines. For more information about creating exercises see the Workbench Documentation for Exercises.

Exercise: Formatting Exercises in a Lesson Site (15 minutes)

Using the approach demonstrated above, format the exercise you designed previously as an exercise in your lesson site.

Exercise: More Practice with Fenced Divs (10 minutes)

Return to the bulleted list of prerequisite knowledge or skills you added to the index.md file of your lesson and use fenced divs to display it in a formatted box with the prereq class. Note that all lesson objectives in fenced divs will be combined into one box at the top of each episode.

Key Points

• Exercises (and solutions) go in blocks using fenced divs in the lesson.
