Quantitative reasoning is an individual's ability to understand quantitative information in context, represent and model such information in various forms, solve real-world problems using mathematical and statistical knowledge, and communicate ideas using quantitative arguments. Quantitative Reasoning (QR) courses are increasingly popular as gateway mathematics for students whose majors lie outside science, technology, engineering, and mathematics.
Professional organizations and policy documents recommend incorporating innovative assessment approaches in QR courses, including continuous and formative assessment. However, many QR instructors are unsure about what types of assessments to use and how to implement such assessments to evaluate and support student learning. Moreover, previous studies, including my pilot research, have found that many QR instructors use traditional, summative assessments.
In this dissertation study, I explored instructors' intentions, behaviors, and reflections on formative assessment, aiming to answer two sets of research questions: (a) What kinds of assessments do QR instructors use? To what extent do the instructors use their assessments as stated in their course syllabus? (b) How do QR instructors implement their assessments to support student learning? In particular, how do instructors implement questioning, feedback, and peer- and self-assessment? What are their related perceptions and experiences?
To examine these questions, I employed a collective case study design, recruiting 8 instructors from eight public postsecondary institutions in Ohio that offered Ohio Transfer 36–approved QR courses. The data sources included the instructors' course documents, semistructured interviews of the instructors, and observations of their teaching. I used six Instructional Quality Assessment (IQA) rubrics for the class observations. I conducted individual and cross-case analyses to compare and contrast the instructors' perceptions and practice (open full item for complete abstract)
