Extract duplicate engagement activities text into reusable child documents

[Copilot]

Engagement activities text was duplicated across 3 course files. Extracted to common child documents using bookdown's child chunk pattern.

Changes

• Created reusable content files:

  • common/content/engagement_activities.Xmd - Standard engagement activities text
  • common/content/engagement_activities_blended.Xmd - Variant for blended sections

• Updated course files to reference engagement activities:

  • 0201_stats.Rmd - Uses standard engagement activities
  • 0202_personality.Rmd - Uses blended variant
  • 0204_testing.Rmd - Uses standard engagement activities

• Fixed existing issues:

  • Corrected broken child reference path in policies.Xmd (./covid.Rmd → 0106_covid.Xmd) for future use
  • Fixed grammar in extracted content ("allow you engage" → "allow you to engage")

Pattern

Before:

## Engagement Activities
There will be multiple engagement activities...

After:

## Engagement Activities
```{r child = './common/content/engagement_activities.Xmd'}

## Note on Policy Sections

General policies (0101-0105) are already rendered as separate bookdown sections and are not duplicated within course files. This PR only addresses the engagement activities text that was duplicated across course syllabi.

@copilot Why are you adding policies to the class-specific page that are covered in the other pages?

@copilot Why are you adding policies to the class-specific page that are covered in the other pages?

You're absolutely right - I misunderstood the bookdown structure. The general policies (0101-0105) are already rendered as separate sections, so duplicating them in each course file would create redundancy, not reduce it.

I've removed those policy includes from all course files in commit ee8849a. The PR now only addresses the actual redundancy: extracting duplicate engagement activities text into reusable child files.

@copilot are there any parts of the policy that are redundant?

@copilot are there any parts of the policy that are redundant?

Yes! The common/content/policies.Xmd file is redundant. It contains an older, condensed version of the same content that's in the individual policy files (0102_engagement.Rmd, 0103_idea.Rmd, 0104_honesty.Rmd, 0105_communcation.Rmd).

Key findings:

• policies.Xmd is NOT currently being used anywhere in the bookdown
• The individual files (0102-0105) are significantly more detailed and up-to-date
• policies.Xmd is missing newer content like the AI ethics policy from 0104_honesty.Rmd
• The individual files are the current authoritative versions

Would you like me to remove policies.Xmd since it's redundant and outdated?
