Larson, L. R.; Lovelace, M. D. – Journal on Excellence in College Teaching, 2013
Classroom questions represent a potentially powerful tool for interacting with students and stimulating critical thinking. However, the efficacy of the question-and-answer approach to teaching is influenced by many factors, such as the type and cognitive level of questions asked as well as students' response time. To examine these factors and…

Reiser, Frank – American Biology Teacher, 2012
The discovery of a Victorian-era microscope slide titled "Grouped Flower Seeds" began an investigation into the scientific and historical background of the antique slide to develop its usefulness as a multidisciplinary tool for PowerPoint presentations usable in contemporary biology classrooms, particularly large-enrollment sections. The resultant…
