We conducted two studies to investigate the extent to which brief, spaced, mastery practice on skills relevant to introductory physics affects student performance. The first study investigated the effect of practice of “specific” physics skills, each one relevant to only one or a few items on the course exam. This study employed a quasiexperimental...
Improving students' views of experimental physics is often an important goal of undergraduate physics laboratory courses. However, traditional lab courses typically include highly guided activities that often do not require or encourage students to engage in the authentic process of experimental physics. Alternatively, open-ended activities in lab...
Knowledge integration is essential to achieve deep conceptual understanding, which requires students to develop well-connected knowledge structures through the central idea of a concept. To effectively represent and analyze knowledge integration, a conceptual framework model on force and motion is developed to map learners' knowledge structures in...
Light interference is an essential topic for understanding the wavelike nature of light, however, there are limited studies on modeling and assessing students’ misconceptions and learning difficulties in this area. Based on the knowledge integration modeling approach, a conceptual framework for light interference is developed and used to model stud...
This paper presents the findings of a validation study for an instrument designed to assess the views on the non-epistemic nature of science (NE-NOS) among pre-service physics teachers (PSPTs). Despite the acknowledged significance of the nature of science (NOS), research has predominantly focused on its epistemological aspects, sidelining non-epis...
Artificial intelligence (AI) technologies have been consistently influencing the progress of education for an extended period, with its impact becoming more significant especially after the launch of ChatGPT-3.5 at the end of November 2022. In the field of physics education, recent research regarding the performance of ChatGPT-3.5 in solving physic...
Work and mechanical energy is a fundamental topic in introductory physics. Studies in existing literature have shown that students have difficulties in understanding work and mechanical energy, particularly the topic of work-energy theorem. To study students’ knowledge integration in learning work and mechanical energy, a conceptual framework model...
Problem solving is considered one of the most critical competencies for life. However, many students may perform well in school yet cannot transfer the skills they learned in school to solve real-world problems, especially in science education. This study discusses the characteristics of the problem from the physics education perspective, based on...
Our strong field simulator method decouples ionization from acceleration and recollision though an XUV-seeded process, allowing for robust multi-dimensional study of strong field recollision that bypasses the limit of tunneling ionization.
WO3 and NiOx films with various thicknesses are deposited by reactive direct current magnetron sputtering. The relationship between film thickness and its electrochromic properties has been investigated. Typical five-layer corresponding complementary electrochromic device (CECD) is fabricated using optimized individual thicknesses of WO3 and NiOx,...

A deep understanding of mechanical waves is crucial for students to succeed in studying many advanced physics topics. Studies in existing literature have revealed that students often have widespread difficulties and misconceptions on wave propagation. This research develops and applies a conceptual framework model to examine students' understanding...
In the Chinese high school physics curriculum, three operational procedures are introduced in electromagnetism, namely right-hand grip rule, left-hand rule, and right-hand rule. This often led to confusion for student to differentiate these rules, and thus often focus on the surface characteristics of the problem or be misled by unrelated details....
Formal understanding of the nature of science (NOS) has been considered to be a major contributor to nurturing students’ scientific literacy. In China, this view has been endorsed in the new standard for high school physics curriculum, which has guided the development of the new generation physics textbooks. Following the analytical framework estab...
The Lawson’s Classroom Test of Scientific Reasoning (LCTSR) is a popular instrument that measures the development of students’ scientific reasoning skills. The instrument has a two-tier question design, which has led to multiple ways of scoring and interpretation. In this research, a method of pattern analysis was proposed and applied to analyze tw...
Problem-solving categorization tasks have been well studied and used as an effective tool for assessment of student knowledge structure. In this study, a traditional free-response categorization test has been modified into a multiple-choice format, and the effectiveness of this new assessment is evaluated. Through randomized testing with Chinese co...
Momentum is a foundational concept in physics. Although it is often taught in introductory mechanics courses, there are a limited number of studies on this topic in the literature. The results from these studies have consistently shown that students have difficulties in understanding momentum, especially the connections between net force, time, and...
A lack of conceptual understanding of electrostatics principles, especially in the context of conductors and insulators, has been observed among a large number of introductory physics students as well as upper-level physics students. This work aims to explore graduate students’ misconceptions on these topics, particularly on how charges are distrib...
Standardized concept inventories (CIs) have been widely used in science, technology, engineering, and mathematics education for assessment of student learning. In practice, there have been concerns regarding the length of the test and possible test-retest memory effect. To address these issues, a recent study developed a method to split a CI into t...
