When describing motion in physics, the selection of a frame of reference is crucial. The graph of a moving object can look quite different based on the frame of reference. In recent years, various tests have been developed to assess the interpretation of kinematic graphs, but none of these tests have specifically addressed differences in reference…

This study presents the development and validation of a novel multiple-choice test designed to assess university students' conceptual understanding of electric field, force, and flux. The test of understanding of electric field, force, and flux was constructed based on the results of previous studies using a phenomenographic approach to classify…

Understanding particle motion in force fields (PMFF), which encompasses the nature of forces and the relationship between force and motion, is fundamental to mastering mechanics and electromagnetism. Effectively solving PMFF-related problems requires advanced reasoning skills and the ability to apply knowledge across diverse contexts. Despite…

A new diagnostic instrument, the Conceptual Survey on Wave Optics (CSWO), was developed and validated on 224 high school students (aged 18-19 years) in Croatia. The process of test construction, which included the testing of 61 items on the total of 712 students is presented. The final version of the test consists of 26 multiple-choice items which…

Research-based multiple-choice questions implemented in class with peer instruction have been shown to be an effective tool for improving students' engagement and learning outcomes. Moreover, multiple-choice questions that are carefully sequenced to build on each other can be particularly helpful for students to develop a systematic understanding…

HOTS is one part of the skills that need to be developed in the 21st Century . This study aims to determine the characteristics of the Fundamental Physics Higher-order Thinking Skill (FundPhysHOTS) test for prospective physics teachers using Item Response Theory (IRT) analysis. This study uses a quantitative approach. 254 prospective physics…

We developed a Quantum Mechanics Conceptual Understanding Survey (QMCUS) in this study. The survey was conducted using a quantitative methodology. A multiple-choice survey of 35 questions was administered to 338 undergraduate students. Three experienced quantum mechanics instructors examined the validity of the survey. The reliability of our…

Assessment of higher-order thinking skills (HOTS) provides few opportunities for students to develop more in-depth knowledge, serving students' ability to identify and solve their problems. One type of instrument for measuring HOTS objectively is the two-tier multiple-choice test (TTMCT). This research is part of the research and development…

The test of understanding of vectors (TUV) is a multiple-choice test that was recently developed to assess student understanding of vector concepts required in introductory physics courses at the university level. In this study, the TUV was administered to 889 first-year students at the University of Zagreb. The Rasch model was used to evaluate…

This study reports on the development, validation, and administration of a 48-item multiple-choice test to assess students' representational fluency of linear functions in a physics context (1D kinematics) and a mathematics context. The test includes three external representations: graphs, tables, and formulas, which result in six possible…

In the context of a generic harmonic oscillator, we investigated students' accuracy in determining the period, frequency, and angular frequency from mathematical and graphical representations. In a series of studies including interviews, free response tests, and multiple-choice tests developed in an iterative process, we assessed students in both…

We present the design, statistical analysis, and validation of a questionnaire to assess students' knowledge about basic aspects of quantum mechanics (QM). The QM evaluation (QME) is a true-false and multiple-choice mixed questionnaire that features 10 two-tier items spanning three relevant themes in quantum mechanics: wave behavior of matter,…

This study investigated the multiple-choice test of understanding of vectors (TUV), by applying item response theory (IRT). The difficulty, discriminatory, and guessing parameters of the TUV items were fit with the three-parameter logistic model of IRT, using the parscale program. The TUV ability is an ability parameter, here estimated assuming…

Standardized conceptual assessment represents a widely used tool for educational researchers interested in student learning within the standard undergraduate physics curriculum. For example, these assessments are often used to measure student learning across educational contexts and instructional strategies. However, to support the large-scale…

Physics literacy plays a crucial part in global technological development as several aspects of science and technology apply concepts and principles of physics in their operations. However, the acquisition of scientific literacy in physics in our society today is not encouraging enough to the desirable standard. Therefore, this study focuses on…
