Abstract

We describe the redesign and classroom testing of an Advancing Secondary Science Education through Tetrahymena (ASSET) module addressing adolescent alcohol, smoking, and vaping. Using the 5E instructional model, the module has students investigate how alcohol, cigarette smoke extract, and vape extract affect the ciliated protozoan Tetrahymena, an accessible proxy for effects on ciliated human respiratory cells. Students analyze public health data, conduct guided and self-designed investigations, and create outreach posters communicating evidence-based risks to peers. We report on observations from two classroom implementations, describing gains in students' ability to articulate toxicology concepts, connect cellular findings to whole-body health, and express intentions to advocate to family and peers to not use or stop using these products. National implementation data show that a majority of students who have learned from this module self-reported reduced likelihood of vaping after completing the lesson.
