Abstract:

As a teaching mode emphasizing knowledge logic， the problem chain teaching is suitable for chemistry courses with strong theoretical and systematic nature. It encourages students to cultivate their critical thinking and problem-solving abilities through independent exploration and discussion， thereby enhancing their interest in chemistry learning. Taking teachers and students of chemistry majors in a certain vocational college as the research objects， based on clarifying the theories of constructivism， problem-based teaching， and zone of proximal development， this study investigates the current application status of the problem chain teaching mode in vocational chemistry teaching through literature review and questionnaire survey， and proposes corresponding chemistry teaching suggestions to enrich the theoretical research on the problem chain teaching method in existing vocational chemistry disciplines and promote the application of the problem chain teaching mode in vocational chemistry classrooms. Through the presentation and resolution of teaching problems， students' traditional learning methods will change accordingly， their thinking level will improve， and the good relationship between teachers and students will be further maintained， while promoting the interaction and communication between both parties.
