Ranga, Jayashree S. – Journal of Chemical Education, 2020
In this study, customized videos and chapter handouts served as pre-class materials for semi-flipped General Chemistry II courses. Face-to-face class time involved engaging students in interactive problem-solving sessions on the board with the instructor and collaborative group activities. During the interactive problem-solving sessions, students…

Zare, Richard N.; Cox, Charles T., Jr.; Murphy, Katherine; Bayas, Camille – Journal of College Science Teaching, 2017
In large, introductory courses, instructors and teaching assistants often struggle to provide detailed feedback on student homework in a timely manner. Here we describe a peer-reviewed homework system that provides quick turnaround while offering flexibility in the construction of homework problems. Homework is administered through a cycle, which…

Gross, David; Pietri, Evava S.; Anderson, Gordon; Moyano-Camihort, Karin; Graham, Mark J. – CBE - Life Sciences Education, 2015
Active-learning environments such as those found in a flipped classroom are known to increase student performance, although how these gains are realized over the course of a semester is less well understood. In an upper-level lecture course designed primarily for biochemistry majors, we examine how students attain improved learning outcomes, as…

Smith, J. Dominic – Chemistry Education Research and Practice, 2013
The idea of ''flipping the classroom'' to make class time more engaging and student-centred has gained ground in recent years. The lecture portion of General Chemistry I and General Chemistry II courses were pushed outside the classroom using pre-recording technology and streaming delivery of content, in order to make in-class time more…

Behmke, Derek A.; Atwood, Charles H. – Chemistry Education Research and Practice, 2013
To a first approximation, human memory is divided into two parts, short-term and long-term. Cognitive Load Theory (CLT) attempts to minimize the short-term memory load while maximizing the memory available for transferring knowledge from short-term to long-term memory. According to CLT there are three types of load, intrinsic, extraneous, and…

Richards-Babb, Michelle; Drelick, Janice; Henry, Zachary; Robertson-Honecker, Jennifer – Journal of College Science Teaching, 2011
To improve students' retention rates in general chemistry, online homework was introduced into our curriculum. Replacing quizzes directly by online homework significantly improved (p less than 0.0005) success rates in second-term general chemistry. Attitudinal Likert survey results indicate that the majority of students completed the online…
