A comprehensive laboratory-style teaching activity involving the synthesis, characterization, and analysis of structure-activity relationships of metal-organic framework (MOF) nanozymes was developed specifically for undergraduates at Tianjin University. The students acquired familiarity with the general approach in synthesizing MOFs by…

Scientific methods have received widespread attention in recent years. Based on the analytical framework derived from Brandon's matrix consisting of four categories of scientific methods, this paper aims to conduct a content analysis to examine how the diversity of scientific methods is represented in college entrance chemistry examination papers…

Concepts related to molecular structure are often challenging for students to visualize and comprehend. Augmented reality has emerged as a promising solution to this problem, providing students with opportunities to manipulate and visualize chemical molecular structures to improve their understanding. Furthermore, collaborative learning…

With the emergence of innovative technologies, including combinatorial chemistry, high-throughput screening, computer-aided drug design (CADD), artificial intelligence (AI) and big data, the importance of drug design in the field of drug discovery and development is increasing. Additionally, education in drug design plays an important role in the…

The computer-aided drug design (CADD) course that spans biochemistry, computational chemistry, medicinal chemistry, and other cutting-edge sciences is considered an important course by pharmaceutical universities in China. The course teaches students how drugs bind to protein targets and exert their biological activities using computer tools, and…

The diversity of scientific methods has received increasing attention in the field of science education. This paper aimed to investigate how preservice chemistry teachers perceive scientific methods and their diversity. Based on the theoretical framework of Brandon's Matrix and previous research, two tasks (i.e., Task 1 "understanding of the…

Background: The views of the nature of science (VNOS) is one of the important goals of science education. According to information processing constructivism, learners' psychological factors that may influence VNOS include scientific argumentation (SA), metacognition (MC) and epistemic beliefs (EB). Purpose: This mixed-methods study aims to analyse…

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)…

This study explored the impact of oxidation-reduction reaction problem difficulty on university students' cognitive load using event-related potentials (ERPs). Forty-eight balanced low and high difficulty problems were designed. Fifteen undergraduate students majoring in chemistry (8 females and 7 males) participated in the study. Results…

The use of the flipped classroom approach in chemistry courses has rapidly increased over the past decade, and it appears that this type of learning environment will play an essential role in improving student success. However, it's crucial to note that the majority of these studies were carried out in higher education environments. There hasn't…

Pedagogical Content Knowledge (PCK) is crucial for effective teaching, but it is a complex and implicit knowledge, especially in chemistry education. Therefore, this study explores the use of the LBCD (Learning by Collaborative Design) model to support PCK development among pre-service chemistry teachers. This study adopted a one-group…

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…

Three visions of scientific literacy have been discussed in the literature of science and chemistry education, but little is known of their embodiment in chemistry curricula. Grounded on the conjunction of the three visions of scientific literacy and the subject matter of chemistry, this study investigated the manifestation of scientific literacy…

Intellectual demands of learning outcomes in the intended curriculum have always been a concern across the field of science education. In particular, the representation of those learning outcomes stipulated by the intended curriculum in science textbooks has become a big issue for both science curriculum studies and science teaching practice. To…

This study aims to evaluate students' ability to process the context information embedded in chemistry problems. To achieve this goal, a diagnostic measurement instrument was developed, comprising 28 short-answer items embedded in seven context-based chemistry tasks. Four hundred and ninety-three ninth-graders took part in the testing in Jiangsu,…
