Educational psychology studies the learning and teaching process to help teachers understand students’ psychological states, thereby improving communication and guidance. This paper explores student communication and guidance strategies from an educational psychology perspective. Communication is the process of information exchange between teachers and students, while guidance is the method to help students solve problems. Through analysis of relevant literature, we found that effective communication can improve students’ learning interest and participation. Guidance strategies need to be adjusted according to students’ age and personality. For example, using simple questions to encourage students to speak can enhance their self-assurance. This paper reviews basic theories of educational psychology, discusses the application of communication strategies such as listening and feedback, and introduces guidance types including individual guidance and group guidance. Finally, practical suggestions are offered to help teachers apply these strategies in teaching. Research shows that these methods can improve students’ learning outcomes. Through this study, we hope to provide educators with practical tools to promote better teacher-student interaction. This paper is based on an analysis of existing literature and does not include new experiments.
