Graduate Students’ Teaching Experiences Improve Their Methodological Research Skills

Teaching is not wasted time. Science, technology, engineering, and mathematics (STEM) graduate students are often encouraged to maximize their engagement with supervised research and minimize teaching obligations. However, the process of teaching students engaged in inquiry provides practice in the application of important research skills. Using a performance rubric, we compared the quality of methodological skills demonstrated in written research proposals for two groups of early career graduate students (those with both teaching and research responsibilities and those with only research responsibilities) at the beginning and end of an academic year. After statistically controlling for preexisting differences between groups, students who both taught and conducted research demonstrate significantly greater improvement in their abilities to generate testable hypotheses and design valid experiments. These results indicate that teaching experience can contribute substantially to the improvement of essential research skills.

Faculty Mentors’, Graduate Students’, and Performance-Based Assessments of Students’ Research Skill Development

Faculty mentorship is thought to be a linchpin of graduate education in STEM disciplines. This mixed-method study investigates agreement between student mentees’ and their faculty mentors’ perceptions of the students’ developing research knowledge and skills in STEM. We also compare both assessments against independent ratings of the students’ written research proposals. In most cases, students and their mentors identified divergent strengths and weaknesses. However, when mentor-mentee pairs did identify the same characteristics, mentors and mentees disagreed about the mentee’s abilities in 44% of cases in the Fall semester and 75% of cases in the Spring semester. When compared against performance-based assessments of mentees’ work, neither faculty mentors’ nor their mentees’ perceptions aligned with rubric scores at rates greater than chance in most categories.
