A central objective of science education is to foster a profound comprehension of fundamental scientific principles among students. Research has shown that a highly integrated knowledge structure is a key factor in achieving a deep understanding. This research has developed a friction force conceptual framework to model students' different…

A laboratory experiment that involves the aqueous and solid phase synthesis, characterization, and solvatochromic properties exploration of red complex [Ni(Me[subscript 3]en)(acac)]BPh[subscript 4] has been developed for first-year undergraduates in the College of Chemistry and Chemical Engineering at Xiamen University. In contrast to previously…

This study aims to create a comprehensive bibliometric map of published scientific articles on e-learning in mathematics education (ME). We used Web of Science (WoS) database to analyzed 341 articles published by 1018 authors representing 79 countries between 2012 and 2022. In this context, we examined scientific articles in terms of scientific…

In physics education, a number of studies have developed assessments of teachers' knowledge of student understanding (KSU) of specific physics concepts with modified versions of existing concept inventories, in which teachers were asked to predict the popular incorrect answers from students. The results provide useful but indirect information to…

Many research studies have shown that lower-secondary school students' scientific literacy depends on their understanding of corresponding scientific concepts. Therefore, it is of great significance to model and assess students' conceptual understanding in learning specific scientific concepts, because it can reflect and diagnose students'…

Redox reaction is a core chemical concept. However, its abstract nature makes it very difficult for students. Students' conceptual structure reflects their mastery of concepts, which helps teachers implement targeted educational strategies. This study aimed to explore the conceptual structures of redox reaction held by students (grades 10 to 12)…

Video instruction has been widely studied and is generally considered as effective as live instruction for teaching scientific concepts and procedures. However, there is limited research on the effectiveness of prerecorded videos for teaching more challenging content. This study conducted a controlled experiment on over 300 high school students to…

Developing a deeper understanding of scientific concepts is one of the primary goals of science education. To improve students' conceptual understanding, it is necessary to explore the major characteristics of their learning process. Informed by previous work on conceptual understanding, this study focuses on the concept of evaporation, exploring…

Chemical thinking is widely acknowledged as a core competency that students should develop in the context of school chemistry. This study aims to develop a measurement instrument to assess students' chemical thinking. We employed the Essential Questions-Perspectives (EQ-P) framework and Structure of Observed Learning Outcome (SOLO) classification…

Achieving knowledge integration for deep learning requires students to develop well-connected knowledge structures through the central idea of a concept. However, a number of studies on student learning in momentum have revealed persistent difficulties in understanding its fundamental concept, particularly in relating net force, time, and change…

This study developed and validated an instrument to investigate senior school students' understanding of electrostatics and provide a cognitive diagnostic assessment of their strengths and weaknesses on the related concepts (e.g., electric charge). The instrument included 20 four-tier multiple-choice items and the development process is organized…

STEM education is widely recognized as a powerful means of cultivating well-rounded future talent. However, challenges such as difficulties in observation, declining learning interests, and the lack of teaching resources present obstacles to the implementation of STEM education in China. Virtual Reality (VR), with its immersive, interactive, and…

With the better understanding of human genome and genetic contributions to human complex diseases, more and more clinical genetic tests have been developed for the prevention, diagnosis, and treatment of human diseases. This has raised new challenges to classroom teaching of medical genetics (MG) in medical education of undergraduates, who are…

In the context of quantum mechanics, students are often asked to use delta functions to solve problems. Here, we investigate three typical problem-solving processes using delta functions: a delta function potential well problem, a position space delta function problem, and a momentum space delta function problem. We studied students'solutions in…

Misconceptions coexisting with scientific understanding pose significant challenges in physics education. Inhibitory control may enable individuals to overcome interference from misconceptions. However, discerning the role of inhibitory control becomes intricate when the saliency of scientific- and misconception-related features varies in a…
