Biology teachers can stimulate students' interest in learning biology by asking questions according to junior high school students' personality and learning characteristics, thus promoting the implementation of students' own biological core literacy. First of all, junior high school biology teachers should pay full attention to the consistency of problems when using them in teaching, so as to ensure that students can actively participate in the thinking and research of problems, and then stimulate students' interest in learning biology; Secondly, pay attention to the construction of intuitive teaching content in teaching, and stimulate junior high school students' interest in biology learning through intuitive ways. In essence, biology itself has a strong intuition. In practical teaching, teachers can use models, specimens and other physical objects, or use multimedia equipment to play videos, pictures and other content, so as to improve the intuition of teaching. In addition, junior high school biology teachers can also apply network information technology to teaching, enrich teaching content through network search, and stimulate students' interest in learning biology; Finally, use cutting-edge knowledge to stimulate students' interest in learning biology. For junior high school students, cutting-edge knowledge has certain novelty, which can effectively stimulate students' desire to learn. Reasonable use of foreword knowledge in biology teaching can also effectively stimulate students' interest in biology learning.
Second, make full use of the effectiveness of biology classroom teaching
Classroom teaching was put forward in the17th century, and it has been used ever since. For students, the classroom is the most important platform for them to learn knowledge and improve their ability. As far as the teaching classroom of junior high school in China is concerned, the time of a class is usually set at 45 minutes. To effectively improve the quality of junior high school biology classroom teaching, teachers are required to make full use of this period of time and adopt teaching contents and methods scientifically and reasonably. First of all, biology teachers should make full use of standardized language forms that are easy for junior high school students to understand, and fundamentally help junior high school students deepen their understanding and memory of biological knowledge, thus improving the classroom teaching effect; Secondly, diversified teaching instruments and advanced multimedia technology are integrated into teaching to assist teaching. The integration of diversified teaching methods and advanced multimedia technology can effectively improve the intuition of biological knowledge teaching and make students improve their learning initiative in critical understanding of knowledge; Finally, make full use of biological experimenters in the classroom, so that students can deepen their understanding of knowledge content through practical observation and promote their own thinking ability to be effectively strengthened.
Thirdly, the application of diversified teaching knowledge in biology classroom teaching.
In order to effectively promote the improvement of junior high school students' biological achievements, biology teachers should fully integrate the extracurricular knowledge that junior high school students can accept in addition to the knowledge content of traditional textbooks, so as to enrich students' understanding of biology. Therefore, in junior high school biology classroom teaching, biology teachers can also implement junior high school students' core literacy in biology through the teaching application of diversified knowledge. For example, in actual teaching, teachers can integrate the knowledge of cloning technology, artificial intelligence and other related biological disciplines into the knowledge content of textbooks, thus enriching students' cognition. For example, in class, teachers can also improve students' interest in biology learning through lectures or knowledge contests, thus improving students' biological core literacy. In addition, teachers can also lead students to go deep into breeding bases, planting centers and other places for in-depth study, thus helping junior high school students broaden their horizons and enrich their own biological knowledge.
Fourth, guide students to explore biological knowledge.
As far as junior high school biology teaching is concerned, there are certain requirements for students' logical thinking ability, so implementing students' core literacy in biology teaching requires teachers to pay attention to cultivating students' inquiry ability. First of all, junior high school biology teachers should pay attention to cultivating students' observation ability in teaching. Teachers are required to set effective observation targets for students in teaching, choose reasonable observation contents, use scientific observation methods, and let students observe what they want to learn wholeheartedly and deeply. After observation, teachers should also guide students to sort out and analyze the observation contents. Therefore, in the cultivation of observation ability, teachers often need to help students to know the objects they want to observe in their study and the observation methods they want to adopt in their study. Students can observe what they want to learn from the outside to the inside, thus promoting the improvement of their inquiry ability. Secondly, junior high school biology teachers should pay attention to the cultivation of students' thinking ability in teaching, so that students can explore the learning content through independent thinking in their study, and then effectively cultivate their own biological core literacy.
Fifth, the rational use of biological experiments in teaching
The implementation of junior high school students' biological core literacy also requires teachers to attach importance to the cultivation of students' own scientific quality in biology teaching, and requires junior high school students to maintain a correct scientific attitude in biology learning and integrate a realistic learning attitude into biology learning. Implementing experiments in biology teaching is to verify the content of biology learning in the most intuitive, effective and scientific way. Therefore, to promote the implementation of junior high school students' own biological core literacy, junior high school biology teachers need to make full use of biological experiments in teaching. On the one hand, in the teaching of biological experiments, teachers should require students to completely record the experimental process and the obtained data, and require students to complete the corresponding experimental report according to the actual experimental process and the final experimental results as well as the data recorded in the experimental process; On the other hand, teachers can mobilize students' emotional cognition by telling experimental stories, and then cultivate students' core literacy.
