Impact Of An Active Learning Intervention On Student Success In An Introductory-Level Biology Course, Cynthia Littlejohn

Dissertations

Large enrollment introductory-level courses with high rates of students receiving a D, F, or withdrawing have been identified within higher education as gateway courses. Students not successfully completing these courses are disproportionately represented by historically and continually marginalized populations, such as low-income, poorly represented ethnic groups, and first-generation students. A form of blended learning called the flipped class model is becoming increasingly prevalent in gateway courses. A flipped class design may reduce the cognitive load by allowing time for processing information before class while cooperative learning may result in a collective working memory effect where social interactions may serve to …

An Investigation Of The Impacts Of Traditional, Virtual, And Hybrid Biological Laboratories On College Students’ Achievement And Motivation To Learn Biology, Shavonda Jackson
