This paper focuses on interdisciplinary practical activities in chemistry, exploring their theoretical connotations and value, key elements and characteristics, as well as the extension of teaching models. Chemistry-based interdisciplinary practical activities reflect the “integration” and “practicality” emphasized in compulsory education curricula, aiming to address complex problems in real-world contexts through interdisciplinary integration and embodied practice. Their core value lies in promoting subject integration, driving instructional transformation, and cultivating key competencies. The essential elements include topic selection, goal setting, context creation, activity design, and evaluation methods. Additionally, the paper analyzes how educational ideas such as STEM, STSE, and SSI expand interdisciplinary practical activities in chemistry, illustrating how these teaching models enrich the design and implementation of such activities.

The quality of laboratory safety education content writing directly affects the effectiveness of science laboratory safety education. The American science textbook Science Explorer: Scientific Inquiry integrates experimental safety education with scientific inquiry, highlights the important values of experimental safety education, such as experimental operation norms (scientific inquiry norms), emergency response ability and students’ safety awareness, etc. The logical and hierarchical structure of its content structure, the contextualization and interactivity of its formal design, the process and reflection of teaching and learning evaluation, are the characteristics of textbook writing that provide useful reference and inspiration for the content writing of experimental safety education in our science textbooks.

Taking “precipitation-dissolution equilibrium” as the theme, “improvement of saline-alkaline land”, which is integrated into civic and political education, is chosen as the contextual material and the challenging task of the whole lesson. Through theoretical analysis and experimental investigation, students are stimulated to construct the research idea of saline-alkali land improvement, the model of precipitation-dissolution equilibrium, and the development of validation experimental model in the continuous interaction with the problem, so as to realize that the concepts and principles of precipitation-dissolution equilibrium can be explored and discovered as the tools for problem solving, and at the same time to realize the structuring of the knowledge correlation, the understanding of the idea, and the structuring of the core concepts. Through the gradual analysis, reflection and updating of the improved solution, students are cultivated to be organized, divergent and innovative in experimental investigation. This lesson effectively promotes the occurrence of deep learning and the development of core literacy.

Taking the “test of drunk driving” as the context, the chemistry experiment exploration review class teaching of senior three was carried out around the reaction of potassium dichromate solution and ethanol. This paper selects the experimental conclusion that the potassium dichromate solution without strong acid acidification does not react with ethanol, which violates students’ cognition, to explore. Combined with the relevant knowledge of chemical reaction principle, the teaching is gradually carried out by using the experimental exploration situation. The conclusion is that the potassium dichromate alcohol detector can use colorimetric detection to detect exhaled alcohol and its content. In theory, the potassium dichromate alcohol detector can be changed from colorimetric type to numerical type to enhance the effectiveness of the exploration review course of senior three chemistry experiments.

According to the curriculum standards, surveys of current teaching practices, and existing research on supramolecular chemistry, it has been found that strengthening teachers’ understanding of the subject matter related to supramolecular chemistry and exploring its disciplinary and pedagogical values are crucial prerequisites for effectively implementing supramolecular education. Propose to understand the teaching content based on the interaction between particles, construct a supramolecular recognition model based on the interaction between particles, and design a clear advanced path of student recognition accordingly. Taking the history of chemistry as the context and setting up progressive teaching tasks, enrich students’ perspectives and form their cognitive approaches, achieving a leap from “molecule construction” to “molecule combination” in chemical thinking. The cognitive model of inter-particle interactions has an overarching quality and can provide a reference for the practice of related teaching content.

Gibbs energy is one of the fundamental concepts in physical chemistry. By tracing back to the high school curriculum standards and multiple editions of high school textbooks, this paper reviewed how the concept of Gibbs energy was introduced and developed in high school textbooks. The content of the six editions of textbooks concerning Gibbs energy was also analyzed and compared. Taking the differences among those textbooks into consideration, this paper analyzed several misconceptions and put forward three pedagogical suggestions, including in-depth interpretation of the changes in the curriculum standards, enhanced understanding of the intention of the textbook revision and exploration of various contextual materials.

The present study aimed to explore the research progress of science teachers’ conceptions about STEM education from an international perspective by reviewing relevant empirical studies. Firstly, according to the philosophical elements (namely ontology, epistemology and axiology), the theoretical framework of teachers’ conceptions about STEM education was constructed and main contents of each research topic were explained. Secondly, relevant international literature published from 2013 to 2024 were collected and screened, and 26 empirical studies about this topic were reviewed, which mainly involved four themes (namely essential characteristics of STEM education, relations between STEM subjects, values of STEM education, and factors affecting STEM education implementation). Finally, based on the review results and actual situation, five suggestions were provided for the training of STEM teachers and the implementation of STEM education in China.

Intuition is an important factor in the potential influence of students’ learning. Students’ intuition will lead to the occurrence of different ideas in the learning process. Those deep-rooted intuitions make it difficult to achieve conceptual transformation. Based on the research on the same conception, this study proposes the rules of intuition to follow, and uses the self-edited questionnaire to explore the intuition of 217 students in junior and senior high school. The results show that the intuition of different rules has different degrees of impact on the formation of students’ differences, and the intuition of junior high school students and senior high school students is not completely consistent. According to the results of 40 students’ interviews, the reason for intuition is summarized, and the corresponding teaching strategies are proposed on this basis.

Based on the conceptual knowledge of junior high school chemistry, an immersive educational game “Chemistry Speed” was developed. Students control the car to move left and right, hit the obstacles that match the theme, get the incentive to accelerate, and reach the finish line in the shortest time. A wrong impact will cause the car to slow down, and the set of mistakes will be organized automatically. Control and experimental groups were set up to carry out an effect test study and it was found that the game helped students’ learning of chemistry concepts (p=0.001). A survey of the game users also found that players recognized the design, content, playability and usefulness of the game.
