Resumen de CASH: Collaborative Activity on the Sash of the Hood
S. Merwin Kennedy, Oliver Dreon
An activity called Collaborative Activity on the Sash of the Hood (CASH) keeps students engaged with lecture-course content during laboratory downtime. In the absence of dedicated recitation times, new opportunities for active learning needed to be found. Students use permanent markers (e.g., Sharpies) to complete their work on the sash of the fume hood. As they monitor laboratory processes safely, learners also work together to complete focused and deliberate problem-solving exercises. Instructors provide just-in-time instruction and formative assessment to help students employ higher-level-thinking skills. This activity has been successfully implemented in courses that have medium to large lecture enrollments with smaller corresponding laboratory sections without a formal recitation component. One example of utilizing CASH to help students engage with electron-pushing formalism is described in detail.
