As we celebrate Henrietta Lacks’ 100th birthday, this web seminar presentation will highlight the contributions of HeLa cells to science and medicine, as well as NIH’s unique agreement with the Lacks’ family related to access to HeLa genomic data. Since Ms. Lacks’ untimely death in 1952, HeLa cells have been a vital tool in biomedical research, leading to an increased understanding of the fundamentals of human health and disease.

RESEARCH AND TEACHING

Comparing Academically Homogeneous and Heterogeneous Groups in an Active Learning Physics Class

Journal of College Science Teaching—July/August 2020 (Volume 49, Issue 6)

By Michael Briggs

Many methods have been developed for managing groups in active learning classes, but little research has been done on the effect of group structure itself. Results are presented for an active learning physics class in which half of the class was placed in academically homogeneous groups while the other half was in heterogeneous groups. Students were given the Conceptual Survey of Electricity and Magnetism as a pretest and posttest, and also filled out surveys on their experiences in their groups. The study was intended to be continued for three years, but was terminated halfway through the second semester as the evidence had become sufficiently compelling that placing half of the class in academically heterogeneous groups was placing them at a significant disadvantage. Student feedback, pretest, and posttest data indicated that low- and middle-performing students benefitted the most from academically homogeneous groups. Results for the one full semester of the study and the rationale for discontinuing are presented.
