What Defines Effective Undergraduate Chemistry Laboratory Instruction?

My interest in undergraduate chemistry laboratory instruction stems from several years as an undergraduate teaching assistant in chemistry, and more recently as an instructor for the introductory organic chemistry course at the University of Regina. Most of what I have learned about being a laboratory TA has come through trial and error, and by listening to students. None of my undergraduate or graduate training in chemistry helped prepare me for teaching in the laboratory. In my positions as instructor at the University of Regina and Wilfrid Laurier University I found myself as counselor to many first time chemistry laboratory TA’s who felt unprepared for the task they were being asked to take on.
 
A review of the teaching effectiveness literature reveals a great deal of material in the area of lecture or small class instruction but relatively little for laboratory instruction. Laboratory instruction is an important aspect of science education that sets it apart from other academic areas. Being a different type of instruction, it is reasonable that effective laboratory instruction may be defined by characteristics that differ from those that define lecture style instruction. The research questions I want to answer are:
 
bullet nWhat qualities or characteristics do students and graduate teaching assistants perceive to be important for effective chemistry laboratory instruction?
bullet nHow do the qualities or characteristics perceived to be important for effective chemistry laboratory instruction differ between students and TAs?
bullet nWhat types of TA actions or behaviors demonstrate these qualities or characteristics?
bullet nHow do these actions or behaviors help students get more out of their laboratory experience?
 
I have chosen to examine student and graduate teaching perceptions of teaching effectiveness for this study because they are the people directly involved with the laboratory instruction. This study itself consists of two phases. The first phase involves a questionnaire with both Likert-type and free response questions. The second phase of this study is more qualitative in nature using a combination of observations, free response questionnaires, and semi-structured interviews.
