Artifact six is a reference letter from Dr. Miller of the University of Prince Edward Island. It is evidence of my instructional competency: Subject matter proficiency, teaching skills, classroom management, and student assessment. The reference letter documents my guest teaching at Dr. Miller’s Ph.D. Advanced Quantitative Research Methodology course (ED 7000). The course was three-credit-hours and structured into four blocks: lecturing, students' presentations, assignments, and project work. It explored a range of quantitative approaches, including experimental, quasi-experimental, and surveys. There were three students in Dr. Miller's class. One researched inclusive education in Canada, another mathematics education in indigenous communities, and the other inclusion and exclusion criteria in large-scale assessments in Canada.

​

I joined the class in the middle of the 2021 Fall Semester. I taught topics including Multiple Regression, Analysis of Variance, Analysis of Covariance (ANCOVA), Correlation Analysis, and Chi-Squared. I evaluated the students' knowledge of quantitative methodologies and gave feedback on presentations. I provided extra meeting times to help students do assignments, presentations, and final projects. Most importantly, I helped them structure their final research papers, rewrite research questions, test hypotheses, conduct data analysis, interpret results, and answer research questions.

​

Guest teaching in the advanced quantitative research methods course was a beneficial experience. It was my most successful course, and Dr. Miller was impressed and happy that I taught in her class. I developed my instructional competency in the class. Of most importance was my lesson on the analysis of covariance: It was my most challenging topic. I had not taught the topic before and was nervous about teaching it for the first time to Ph.D. students. My practice data for SPSS analysis was real and messy data, and I had little understanding of math anxiety, the research area the data covered. I enhanced my understanding by reading articles and textbooks on math anxiety and the analysis of covariance, and I polished my teaching skills by watching YouTube videos. Moreover, I managed my class by posing critical questions and giving exercises that probed my students' understanding.

This section reflected on artifact six, guest teacher: Advanced quantitative research methods, UPEI Faculty of Education Ph.D. in Educational Studies Program. In the future, I will apply to teach as a sessional instructor or offer to teach for free as a guest instructor, starting with the Introduction to Research course in the faculty of education. I will continue to build instructional competency and position myself better for academic employment.
