Modeling instruction: Positive attitudinal shifts in introductory physics measured with CLASS

Among the most surprising findings in Physics Education Research is the lack of positive results on attitudinal measures, such as Colorado Learning Attitudes about Science Survey (CLASS) and Maryland Physics Expectations Survey (MPEX). The uniformity with which physics teaching manages to negatively shift attitudes toward physics learning is striking. Strategies which have been shown to improve conceptual learning, such as interactive engagement and studio-format classes, provide more authentic science experiences for students; yet do not seem to be sufficient to produce positive attitudinal results. Florida International University’s Physics Education Research Group has implemented Modeling Instruction in University Physics classes as part of an overall effort toward building a research and learning community. Modeling Instruction is explicitly designed to engage students in scientific practices that include model building, validation, and revision. Results from a preinstruction/postinstruction CLASS measurement show attitudinal improvements through both semesters of an introductory physics sequence, as well as over the entire two-course sequence. In this Brief Report, we report positive shifts from the CLASS in one section of a modeling-based introductory physics sequence, for both mechanics (N=22) and electricity and magnetism (N=23) . Using the CLASS results and follow up interviews, we examine how these results reflect on modeling instruction and the unique student community and population at FIU.

Students know what physicists believe, but they don’t agree: A study using the CLASS survey

We measured what students perceive physicists to believe about physics and solving physics problems and how those perceptions differ from the students’ personal beliefs. In this study, we used a modified version of the Colorado Learning Attitudes about Science Survey which asked students to respond to each statement with both their personal belief and the response they thought a physicist would give. Students from three different types of university introductory physics courses were studied. Students who have not yet taken physics in college have a surprisingly accurate idea of what physicists believe about physics no matter what their high school background and what physics courses they choose to take in college. These ideas are largely unaffected by their college physics instruction. In contrast, students’ personal beliefs about physics differ with varying high school physics backgrounds and college physics courses in which they enroll, and these beliefs are affected by college physics instruction. Women have a larger difference between their reported personal beliefs and their perceptions of physicists’ beliefs than do men.
