Graduate teaching assistants (GTAs)
play an essential role in the
teaching of introductory chemistry courses at many higher education
institutions. On the basis of best practices suggested by the literature,
we developed our GTA training course to focus on modeling best practices
in the classroom, providing opportunities for incoming GTAs to try
new teaching methodologies and reflect on their teaching, and observing
and giving feedback on their teaching throughout the course. Here
we describe the structure of a GTA training course, provide our course
evaluation methods, and present end-of-semester survey data from trainee
GTAs (t-GTAs) and experienced GTA (e-GTA) volunteers that helped with
the course. The findings indicate that the majority of t-GTAs appreciated
the course structure and topics. In particular, t-GTAs found discussions
helped them learn the material and greatly appreciated the opportunity
to observe someone teaching and be observed during their teaching.
Several areas for improvement were also identified, including more
opportunities to observe peers, additional topics such as classroom
management, and greater support in applying course topics to individual
teaching environments. e-GTAs on the other hand reported positively
on how the course impacted their own professional development through
honing their observational skills and their ability to provide constructive
feedback, as well as adding to their own knowledge on teaching methodologies
through observing t-GTAs. Intending to provide insight on how course
evaluation data can be used to inform change, we discuss our findings
in terms of the specific changes that will be made at Purdue Chemistry
in future course iterations, as well as in terms of implementing or
revising GTA training at other institutions. We hope that the course
structure, evaluation approach, and data described here provide insight
into other institutions interested in changing their own GTA programs.
