Goacher, Robyn E.; Kline, Cynthia M.; Targus, Alexis; Vermette, Paul J. – Journal of College Science Teaching, 2017
We describe how a practical instructional development process helped a first-year assistant professor rapidly develop, implement, and assess the impact on her Analytical Chemistry course caused by three changes: (a) moving the lab into the same semester as the lecture, (b) developing a more collaborative classroom environment, and (c) increasing…

Vondracek, Mark – Science Teacher, 2009
Teachers know what a daunting job it can be to ensure that all students in a class learn effectively. In addition to the usual difficulties of gaining everyone's attention at once, instructors also run into the issue of preferred learning styles. In any classroom environment, the same topic is taught to multiple students, and each student may…

"Studio" Classrooms.
DeLoughry, Thomas J. – Chronicle of Higher Education, 1995
At Rensselaer Polytechnic Institute (NY), some introductory science and engineering classes are taught in "studios," where students work on problems on computers, followed by a mini-lecture or summary and class discussion. The method replaces impersonal large-group lectures with less expensive, more effective instruction and more…
