Research skills development. Students will focus on building the skill set necessary to conduct research for the dissertation with an emphasis on background fundamental issues in STEM education research. It will build on exploration, analysis, and writing skills critical to the research process. The course also addresses ethics of research, including issues associated with human subjects research. Students will learn skills that give shape to their thinking. As part of the course, students will be expected to identify a problem for which they will conduct a pilot study during the Introductory and Preparatory phases of the doctoral program.

Dr. Orrill holds a Ph.D. in Instructional Systems Technology from Indiana University. She joined the faculty at UMass Dartmouth in 2010 after serving as a Research Scientist at the University of Georgia for nearly a decade. Dr. Orrill has taught a wide variety of courses in the MAT program and the Mathematics Education and STEM Education PhD programs including: Math Methods for Middle School Teachers, Math Methods for High School Teachers, Introduction to Mathematics Education Research, Introduction to Science Education Research, Proportional Reasoning for Middle School Teachers, K-12 STEM Reform in a Political Context, Developing Research Skills Part 2, and Research on Teacher Education. She has two main research areas. First, she has been examining how middle school math teachers understand proportions and fractions, how we can use emerging assessment models to better understand teacher knowledge, and how we can create instructional materials to support teachers’ understandings. Second, she is interested in how to integrate computational thinking into elementary math classrooms. All of this work has been done in ongoing, long-term partnerships with schools and teachers. Dr. Orrill has published more than 80 journal articles, chapters, and published proceedings in venues that include Journal of Research for Mathematics Education, Mathematical Thinking and Learning, Educational Researcher, and Journal of Mathematics Teacher Education. She has also presented over 100 papers at national and international conferences. Dr. Orrill has also been awarded more than 25 grants with a net value in excess of $8 million.
