Lessons learned from the implementation and assessment of student-centered methodologies

Abstract

The cAcL2 approach (“concept Advancement through chemistry Lab-Lecture”) incorporates three major educational methodologies into one: a student-centered approach, the full integration of lecture and laboratory formats, and hands-on activity based-instruction. This format has been tested for cognitive and attitudinal gains in students and the results clearly point out to its benefits. Instructional materials for a one-year general chemistry sequence have been developed to facilitate its implementation in classrooms. The most important aspects of the format with tested practices are discussed while challenges and implications of findings are shared in order to assist instructors interested in implementing innovative formats of instruction such this one, the cAcL2.Peer Reviewe
