The COVID-19 outbreak represented a remarkable challenge in universities and colleges since it forced the transition from a face-to-face model in classrooms and laboratories to a remote, online model using computers, tablets, and cell phones. In Mexico and other Latin American countries, the return to educational activities was a slow-paced…

A multioutcome, guided inquiry-based liquid--liquid extraction (LLE) experiment has been designed for introductory organic chemistry. Multiple outcomes were established by identifying a series of red and blue dyes that are (1) soluble in organic solvent, (2) soluble in aqueous solution, or (3) soluble in either the organic or aqueous layers by…

Contemporary curriculum demands the development of both problem solving skills and negotiative skills required for collaborative group work. Tasks are required that create the best possible conditions for students to develop both of these skill sets. Open-ended tasks have been shown to provide these conditions, but they also require the teacher to…

Although science is a creative endeavor (NRC 1996, p. 46), many students think they are not encouraged--or even allowed--to be creative in the laboratory. When students think there is only one correct way to do a lab, their creativity is inhibited. Park and Seung (2008) argue for the importance of creativity in science classrooms and for the…

Inquiry and lecture/lab methods of instruction yield different results in conceptual and problem-solving tests, while no difference exists in factual tests. The author recommends that the inquiry method of teaching be refined so that it can become a practical classroom instructional strategy. (CT)

The pendulum and balance beam were studied. The principal question addressed was whether students could substantially and quickly benefit from a teaching strategy explicitly designed to promote transfer. About half the subjects could acquire in brief time a procedure for transferring knowledge to novel tasks. (MP)

For some time industrial educators have been concerned with effective methods of teaching electricity-electronics. This study compared the relative effectiveness of the predesigned-circuit method with a student-designed circuit method for students' laboratory experience. Using one unit of college-level industrial education…
