Include non-lecture learning activities in class to improve student learning and retention in STEM disciplines

October 14, 2014

Freeman et al. (2014) examined 225 scholarship of teaching and learning (SoTL) studies that compared the impact of active learning components included in the class meetings (versus laboratory, homework, or recitation sections) to traditional lecture-only class meetings. Importantly, the metrics for learning used in these SoTL projects included equivalent exams, concept inventories, or other assessments administered to students enrolled in traditional lecture classes and classes that included active learning, which the researchers defined as use of any of a variety of active learning strategies:

  • Occasional group problem-solving
  • Worksheets or tutorials completed during class
  • Posing questions for personal response systems (clickers), with or without peer instruction
  • Studio or workshop course designs.

On average, students enrolled in the active learning classes earned a half-letter grade or higher on course exams. Moreover, retention improved significantly when classes included at least a few active learning components. Average failure rates in the active learning classes were 21.8%, compared to a 33.8% failure rate in traditional lecture classes. Thus, instructors who include active learning components in their STEM class meetings can increase student learning, with direct benefits for student retention. The effect of active learning improves with smaller classes (fewer than 50 students), but Freeman et al. found a significant benefit even in large enrollment STEM classes.

Interestingly, the authors note that “if the experiments analyzed here had been conducted as randomized controlled trials of medical interventions, they may have been stopped for benefit – meaning that enrolling patients in the control condition might be discontinued because the treatment being tested was clearly more beneficial.” (p. 4) That is, the benefit of including at least some active learning components during class meetings for STEM classes is so great that failure to include these activities would be considered analogous to an unethical denial of a known beneficial medical treatment.

These findings do not mean that instructors should or must abandon traditional lectures entirely. However, the benefits for student learning are large enough that instructors should find a way to include a few non-lecture learning activities during traditional “lecture” classes.
