Abstract

Explain skills are a basic teaching skills, but also the teachers in the classroom teaching skills most commonly used one. Explain why skills are widely used, because it can in the shortest possible time within which a large number of students passing indirect experience, easy to operate, regardless of time or educational resources are a great savings. However, based on existing skills to explain the current situation of research, whether it is normal students or teachers in explaining the use of the skills are present in many deficiencies. In this paper, the application of biological teachers on skills as a starting point to explain the biology teaching theory as the basis for teaching the true reality as the basis, through literature research and classroom observation and case analysis and other methods, the combination of theory and practice, aims to analyze the Currently teaching of biology to explain the problems, and for the teaching of biology to explain the specific issues of optimization strategies, and explore to improve the skills of teachers on biological pathways, the fundamental purpose is to promote effective teaching biology classroom. This study includes the following four parts: the first part discusses the theoretical basis to explain the skills. Respectively, from meaningful learning theory, cognitive psychology assimilation theory, migration theory, educational communication theory four aspects educational theory to explain the skills of teachers to apply for biological guiding significance. The second part, with characteristics discussed Biology Biological teaching skill to explain the elements, which form the structure to explain, provide examples, forms a connection with other teaching skills match, for emphasis, access to the feed. Explained by analyzing the elements of skill, and further analysis to explain the nature of the content, enrich the connotation of skills to explain. The third part, on the basis of preliminary studies, according to the theory of teaching evaluation, follow the basic principles of assessment, evaluation combine to explain the concept of skill to construct to explain the biology teaching skills evaluation, the use of literature and expert opinions average method establishes the teaching of biology to explain Skills Assessment Scale. Details of the rating scale measurement methods, the advantage of simple, convenient and easy, suitable for biological evaluation of teachers on skills everyday. Finally, 10 teachers apply this same teaching evaluation form for the video to explain the skills evaluation, conducted reliability test, the test results indicate a high degree of consistency reliability rating scale. The fourth part, the use of literature, classroom observation and case analysis, analyzed and summarized in the biology classroom teachers on common problems, including: teachers on the front, could not very well understand the students' practical; failed to play the subjectivity of students; explain the structure of classroom grasp enough. Combined with biological teaching case optimization strategies proposed to explain the teaching of biology, including: According to students' prior knowledge and experience to construct to explain the structure; effective use of the skills to explain, guide students to scientific thinking; guide students to actively participate; research to explain the content and focus; utilize timely explain the error correction and breakthrough thinking disorder. Finally, based on the contents of the study, in order to improve teachers on skills for the purpose of making recommendations from three aspects: the promotion of biological science teacher professional development, improve teaching skills; create an enabling teachers and students to develop evaluation systems: teachers should wash Reflections on Teaching.
