Description¶

The article reports that pre-class videos "cannot be too long and should be restricted to 20 min, which could be acceptable for most students". This strategy addresses the preparation burden that may cause negative student attitudes toward flipped classrooms. It is drawn from the authors' discussion of influential factors for flipped classroom effectiveness.

Design Implications¶

Context¶

Requirements¶

• Pre-class video materials must be prepared in advance and kept within the recommended duration

Constraints¶

• Excessive preparation time and resource requirements may negatively impact effectiveness and student attitudes

Target Learners¶

• Undergraduate clinical medicine students

Target Learning Goals¶

• Theoretical knowledge
• Practical clinical skills

Related Strategies¶

• Limit flipped classroom video duration to around 20 minutes and use opening quizzes
• Keep online lecture videos under twenty minutes and segment by topic with speed control
• Micro Flipped Classroom
• Prioritize high-quality RCTs with standardized assessment tools and subjective outcomes in future flipped classroom research
• Keep pre-class teaching videos short (10–20 minutes), goal-targeted, and followed by checking homework
