A Conceptual Framework for Graduate Teaching Assistant Professional Development Evaluation and Research.

Area of Science:

• Biology Education
• Higher Education Pedagogy

Background:

• Biology graduate teaching assistants (GTAs) are crucial for introductory course instruction.
• There is a significant gap in empirical data regarding effective GTA preparation and professional development.

Purpose of the Study:

• To propose a conceptual framework for evaluating biology GTA teaching professional development (TPD) programs.
• To guide research and evaluation by defining key outcome, contextual, and moderating variables.

Main Methods:

• The framework categorizes variables into outcome, contextual, and moderating types.
• It suggests focusing evaluation on GTA cognition, teaching practice, and undergraduate learning outcomes.
• Example evaluation questions and assessment instruments are provided for each outcome variable.

Main Results:

• The proposed framework shifts evaluation focus from mere GTA satisfaction to measurable impacts on teaching and learning.
• It offers a structured approach for designing TPD evaluations and research studies.
• The framework facilitates national-level data coordination and synthesis.

Conclusions:

• The conceptual framework provides a robust model for assessing biology GTA TPD effectiveness.
• It establishes a common language and structure for research across institutions.
• Implementing this framework can lead to improved GTA training and enhanced undergraduate education.
