Establishing students' dominant position in biology teaching is the basic idea of the new round of curriculum reform, and improving classroom teaching efficiency is the key to the new round of classroom teaching reform. Establishing students' dominant position in classroom teaching lies in guiding students to actively participate in the whole learning process, giving full play to students' enthusiasm, initiative and creativity, and making students truly become the masters of learning. Student-oriented teaching in biology teaching aims at achieving quality education, taking cultivating students' interest and sense of responsibility as a breakthrough. Under the guidance of the new curriculum reform, based on the classroom and combining with the reality, it creates a lively teaching situation, optimizes the teaching process, promotes classroom harmony, and allows students to actively learn and develop. First, the theoretical basis of student-oriented education The concept of student-oriented education has been reflected in educational thoughts at all times and in all countries. Paulia thinks: "The best way to learn anything is to discover it yourself." In order to study effectively, students should find as many materials as possible under given conditions, stimulate interest and find fun from them, and study in an orderly manner under the active guidance of teachers. The core idea of Guo's "student-oriented education" theory is to highly respect students, fully trust students, and rely on students in an all-round way, instead of relying mainly on teachers and students to learn. The role and value of teachers are embodied in mobilizing students' internal enthusiasm to the greatest extent and organizing students to study independently. Latinius expressed his educational ideal in his "On Great Education": "Find an educational method, so that teachers can teach less, students can learn more, schools can be less noisy, disgusting and useless, and there is a leisurely, happy and solid pace." Second, the specific methods of implementing student-oriented education in biology teaching 1, setting goals and stimulating interest motivation Teaching goals are important links to transform teaching requirements into behaviors and internal needs. Clear teaching objectives make the bilateral activities of teaching and learning people-centered, and at the same time help to cultivate students' goal motivation and help students learn on a voluntary and independent basis. For example, change teaching plan into learning plan, change teaching plan into learning plan, and let students build their own knowledge structure. 2. Stimulate interest and cultivate a sense of participation. First, teachers can use language to guide interest.
