This case study of the redesign and implementation of an introductory physics course focused on the laboratory component and specifically the teaching of measurement and measurement uncertainty, which is essential to an informed view of the nature of science (physics). The research questions systematically considered the elements of measurement ...
We focus in particular on the question of how Rasch modeling can improve some common practices in PER, such as test construction, test evaluation, and calculation of student gain on PER diagnostic instruments.
3 Ιαν 2020 · These questions include constructed-response (CR) questions and two-tiered questions. Underwood et al. (2018) also argued that questions should address core and cross-cutting ideas and ask students to consider how scientific phenomena occur so that they can construct explanations and engage in argumentation.
7 Ιαν 2016 · With a dedicated monthly column, Nature Physics draws attention to metrology. And a set of Commentaries in this issue focuses on various aspects of thermometry.
19 Ιουλ 2023 · In this research, we investigate advanced physics student thinking about uncertainty by asking them conceptual questions about how a hypothetical distribution of measurements would change if “more or better data were collected in four. ” “ ” different experimental scenarios.
17 Ιουν 2019 · It is the very beginning of a modeling process. Take for example a ball rolling across the floor, quantification involves thinking of measurable quantities that can help describe the motion (e.g. time intervals, distances), the arithmetic involved in constructing rates, and their units.
