Background: This auto-ethnographic study describes research conducted in a science teacher education program at a state university in Turkey, where I had taught the 'laboratory applications' course for the four previous years. While the students learned the basic skills needed to implement a laboratory course, I detected some deficiencies in their…

This study investigated the possible connection between effective laboratory activities and student performance on lecture exams. In a traditional undergraduate organic chemistry course for non-science majors, students could predict the products of organic reactions, but struggled to provide reaction mechanisms for those same reactions, despite…

Graduate teaching assistants (TAs) are hired to assume some of the teaching duties in large general chemistry programs. They serve as liaisons between students enrolled in the course and the professor in charge. Being assigned to teach immediately on arrival at graduate school may be overwhelming to novice graduate students. When sending them into…

Discusses preliminary research on a new heuristic tool for learning from laboratory activities in secondary science. Finds that use of the science writing heuristic facilitated students in generating meaning from data; making connections among procedures, data, evidence, and claims; and engaging in metacognition.
