A. C. Cooper; J. B. Osness; S. D. Hester; M. S. Bolger – CBE - Life Sciences Education, 2024
Undergraduate laboratory courses can provide opportunities for students to participate in science practices. This requires rethinking both curricula and instruction. Science practice--based courses require students to be positioned as epistemic agents, implying a shift in instructor role. Teaching assistants (TAs) are the primary instructors for…

Turk, Judith K.; Young, Rebecca A. – Journal of Geoscience Education, 2022
Estimation of soil texture is an essential skill for soil scientists, but a difficult skill to learn. We compared two approaches for teaching soil texture: the traditional flowchart approach and an experimental self-calibration method. Three lab sections of an introductory soil science class were assigned to learn by the flowchart method (n = 60)…

Williams; Zachary Conley; Hinton Antentor Jr. – Advances in Physiology Education, 2024
Physiology is an important field for students to gain a better understanding of biological mechanisms. Yet, many students often find it difficult to learn from lectures, resulting in poor retention. Here, we utilize a learning workshop model to teach students at different levels ranging from middle school to undergraduate. We specifically designed…

Williams, Ursula J.; Dries, Daniel R. – Journal of Chemical Education, 2022
In order to evaluate students' development of scientific competence at the intermediate level, a guided-inquiry course was developed to increase student independence, including opportunities for project ownership and significant collaborative learning expectations. A survey was developed to assess students' experiences learning the scientific…
