In upper-secondary chemistry education, the concept of 'Amount of Substance' occupies a central position within the computation framework. However, comprehending this concept often poses a challenge for students. To address this issue, our study aimed to design and implement a computation skills test to assess the varying levels of students'…

This study examined the impact of integrating virtual science inquiry activities with Predict-Observe-Explain (POE) teaching strategies on 5th graders' understanding of science concepts and epistemic beliefs in science. A cohort of 80 5th graders (mean age of 12 years old, 40 boys and 40 girls) from a public primary school in North China took part…

Human ageing and age-associated diseases are among the greatest challenges and financial burdens faced by developed countries. Unfortunately, undergraduate students often do not experience any laboratory training in ageing research in the current laboratory curriculum of majors in biology, biotechnology, or medicine. In this study, we developed…

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…

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…

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…

The Next Generation Science Standards regard biological structures at both the micro and macro levels as a core idea of life sciences and expect students to understand animals have external structures that perform diverse functions. Using the common creature of bees as a case, this study aimed to ascertain teenage students' ideas of bees through…

Students hold a variety of initial (mis)conceptions that are inconsistent with scientific knowledge and hinder their physics learning. The initial (mis)conceptions could coexist with the scientific ones, even after a conceptual change. Inhibitory control may help overcome initial (mis)conceptions. This study investigated if and how inhibitory…

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'…

Active participation in project-based learning (PBL) could develop students` knowledge and crucial learning skills across various disciplines. However, the implementation of PBL in the K-12 classroom is usually impeded by the stepby-step PBL cycle. Micro project-based learning (MPBL), which advocates and adheres to the learning principles and…

Science identity, encompassing perceptions of competence, interest, and recognition in science, alongside learning self-efficacy reflecting confidence to master science skills, are key drivers of outcomes. However, developmental patterns likely vary across contexts. Participants were 512 Chinese students spanning grades 1-3 who completed the…

Physics education aims to develop sophisticated thinking abilities and enhance conceptual depth, but student interest has decreased, emphasizing the importance of teacher quality in fostering success and positive attitudes. The aim of the study was to examine the physics teachers' self-efficacy, innovative teaching, and comprehensive teaching…

This study utilized the SEC (Survey of Enacted Curriculum) method to examine the alignment between Chinese high school chemistry curriculum standards (HSCCS) and the assessment of 'Chemical Reaction Principles' in the National College Entrance Examinations (NCEEs). The HSCCS and NCEEs were coded into two-dimensional matrices separately using SPSS,…

The gamification of learning has increased in popularity in recent years as a tool for enhancing student engagement and attainment. In undergraduate chemistry courses, hybridization is a fundamental concept that students need to master in order to understand introductory organic and inorganic topics. This study focused on the development of a card…

Redox reaction is an important concept in chemistry, and a well-organized knowledge structure of redox reaction is beneficial for concept learning. This study investigated the knowledge structure regarding redox reaction from 459 Grade 10 students. The pool of 15 redox reaction concepts was developed by content analysis, questionnaire survey, and…
