Guidance & Summary

• Each short video becomes a full lesson rather than a passive viewing worksheet.
• Students distinguish source claims, evidence, assumptions, uncertainty, interpretation, and value judgments.
• Questions use changed-cue reasoning and transfer rather than simple recall whenever appropriate.
• Sensitive topics are handled with third-person cases and no required personal disclosure.

Differentiation Options

• Preview only essential vocabulary.
• Replay difficult sections and use timestamps to return to evidence.
• Use partner discussion before written response.
• Assign selected assessment-bank items rather than every item when time is limited.
• For advanced students, add counterarguments, alternative explanations, or explicit scope limits.

New Optional Video Companion (used with YouTube)

The free Classroom Video Guide Companion Chrome extension can automatically pause YouTube at question timestamps and display prompts during viewing. It can make whole-class, small-group, and independent video lessons easier to facilitate. The curriculum works normally without the extension.
