This research was conducted during one semester in four different classes that were taught biology by using four different teaching strategies: Problem-based learning (PBL), Jigsaw, PBL integrated with Jigsaw (PBLJigsaw), and direct teaching. This research explored the correlation between metacognition (metacognitive awareness and metacognitive…

This paper describes the development of a first-year chemical engineering course over 5 years through action research based on evidence from student feedback. As a result of this research, the course has evolved into a blended approach which incorporates problem based learning (PBL) and online learning tools. Through the use of PBL, the students…

An experimental study was designed to study the effectiveness of Problem Based Learning (PBL) in the context of higher education in an urban-city university in Lima, Peru. In the fall semester of 2004, eleven sections of Chemistry 1 were offered to first year students in the College of Science at this University. In six of these eleven sections…
