The Automated Analysis of Constructed Responses (AACR, pronounced "acer") research group consists of researchers from seven universities with backgrounds in various STEM disciplines (biology, chemistry, engineering, and statistics), assessment and educational research. We are exploring the use of computerized lexical analysis of students’ writing in large enrollment undergraduate STEM courses. Our hope is to show that these techniques have potential for improving assessment practices across STEM disciplines.
We are excited to announce two recently published articles:
Andrea Bierema, Anne-Marie Hoskinson, Rosa Moscarella, Alex Lyford, Kevin Haudek, John Merrill & Mark Urban-Lurain (2020) Quantifying cognitive bias in educational researchers, International Journal of Research & Method in Education, DOI: 10.1080/1743727X.2020.1804541
Zhai, X., Haudek, K.C., Stuhlsatz, M. & Wilson, C. (2020) Evaluation of construct-irrelevant variance yielded by machine and human scoring of a science teacher PCK constructed response assessment. Studies in Education Evaluation. 67. DOI:10.1016/j.stueduc.2020.100916
Congratulations to our lead authors, Andrea Bierema and Xiaoming Zhai and their writing teams!
