Research in general chemistry laboratory instruction has rarely focused on the impact of the learning environment on the graduate teaching assistants (GTAs). We decided to investigate the effect that facilitating a well established cooperative problem-based chemistry laboratory has on GTAs' epistemological and metacognitive development, and how…

Most educators and scientists would agree that science laboratory instruction has the potential of developing science practices fundamental to achieving scientific literacy. However, there is scant evidence to support that this potential is realized, particularly in tertiary level education. This paper reports qualitative results from a sequential…

Metacognition is fundamental in achieving understanding of chemistry and developing of problem solving skills. This paper describes an across-method-and-time instrument designed to assess the use of metacognition in chemistry problem solving. This multi method instrument combines a self report, namely the Metacognitive Activities Inventory…
