... arguments and generally scored better on the items. Furthermore, some PER instruments designed to evaluate students' understanding of certain areas of physics also contain many items with graphs. For example, Lichtenberger et al. (2017) developed the kinematics concept test (KCT) to evaluate...

... and uncertainty skills In contrast to hands-on skills, the PER literature is imbued with studies evaluating students' understanding and application of data analysis and measurement uncertainty procedures. This abundance likely reflects the general sense of importance these skills have in physics curricula. Many...

... instruction has formed an important part of physics instruction for over a century. Within the United States, a survey of physics education practices from 1884 indicated that many faculty thought laboratory work should be a regular component of physics instruction ( Wead, 1884 ). It has generally seemed...

... instruments have been developed and used in different topics and grade levels in the PER. Assessment of Physics Understanding for Multiple Purposes Assessment is a process for determining the nature and extent of student learning and development. It can be broadly defined as any of a variety of procedures...

... Only one study focused on the development of a test instrument depicting grade 11 students' understanding of light phenomena ( Ndihokubwayo et al., 2020b ). General theoretical frame of teaching and learning (RQ2) There are many different theories about the way people learn. This section...

... the use of the various instruments and devices, the procedures for processing, the presentation of the measurements and the preparation of an experiment (organization and collection of materials, preparation of samples), (b) they give the opportunity of (virtual) tests and experiments under various...

... quantitative studies, they use evidence to make and support claims about physics learning and teaching. In this chapter, we provide an introduction to strategies and procedures for collecting and analyzing qualitative data and discuss other aspects of qualitative research such as theoretical framing...

... ( Hofstein and Lunetta, 2004 ; Psillos and Niedderer, 2006 ; and NRC, 2013 ). However, students face several difficulties in the physical laboratory: being involved in time-consuming procedures taking measurements and transforming them into data, focusing often to instrument manipulations and task...

... out a gender-neutral edit of the quote to include in an assignment for my course (General Physics I). But my teaching assistants convinced me that editing would do different harm, of disguising a history that remains with us, and the quote went in as above. That history, and helpful feedback from...

... of material agency has brought attention to material culture, so experimental materials and procedures have become crucial to studying building physics. It means analyzing how instruments and experiments are constructed and reconstructed, the materials used in these processes, and the written or unwritten...

...–6-20. Introduction Currently, renewable energies, particularly photovoltaics (PVs), are becoming one of the most significant sources for electricity generation worldwide. With reference to the International Energy Agency ( Snapshot of Global PV Markets, 2022 ), the total cumulative installed...

... that the results based on assessments with the VNOS, VOSI, or VASI instruments are tied to their specific way to spell out the nature of science or scientific inquiry and cannot be easily generalized to different conceptualizations. However, this controversial debate should not obscure the fact that the different...

These discussions will be presented in a general context that is not restricted to energy systems; however, to provide an energy systems context, we will at intervals relate the principles to energy systems through discussion of an enhanced...

These rubrics encourage students to focus on effective ways of solving problems rather...
