Application Of Anchored Instruction Model In The Teaching Of "Chemical Substances Around" In Junior High School

With the continuous advancement of the reform of the chemistry curriculum,teaching has begun to focus on the overall development of students and the cultivation of comprehensive abilities,emphasizing student-centered,giving full play to students' main role,and training students' innovative abilities and comprehensive talents.Based on these ideas,how to improve the teaching quality of junior high school chemistry has also become a concern in the education community.As an entry stage of chemistry learning,junior high school chemistry requires students to learn in some ways,pay attention to the cultivation of students' abilities,and lay a good foundation for chemistry learning..In junior high school chemistry,the “chemicals substances around”plays an important part,which contains the main knowledge points of middle school chemistry,with a wide range and difficulties,with strong representation,and students have more difficulties in studying.The anchored instruction model under the guidance of constructivism emphasizes the introduction of real problems into the classroom,enabling students to experience problems and explore them independently in real situations,and enables students to construct knowledge independently in the process of problem solving,thereby to transform students' learning attitude,develop students' ability to find and solve problems,promote their knowledge transferability,develop good study habits,and improve students' learning efficiency.This article introduces the anchored instruction model into the teaching of "chemical substances around".Based on the characteristics ofchemistry in junior high school and the analysis of the contents of "chemical substances around",the design link based on the anchored instruction model is based on the design link "chemical substances around" are designed and implemented in anchored instruction to solve the problems in teaching and improve the quality of classroom teaching.In the practice school,the experimental classes and classes in comparative were selected for educational experiments,and the test results of the two class students are comprehensively analyzed,combined with the results of the questionnaire survey and interview to study the application effect of the anchored instruction model.Through the analysis of the experimental results,the following conclusions are obtained: Firstly,the application of the anchoring teaching model to the teaching of "chemical substances around us" is conducive to changing the students 'attitudes towards this part of the content,so that the students' enthusiasm for learning can be improved.Secondly,the anchored instruction model makes students' thinking more flexible,and cultivates students' ability to transfer knowledge,so as to solve the problems encountered,thereby improving students' academic performance.Thirdly,the anchored instruction model improves students' learning methods and enables students to form certain habits of autonomous learning and cooperative learning.
