Design And Research Of Junior Middle School Chemistry Experiment Guidance Case Under The Background Of New Curriculum Reform

With the advancement of the basic education reform,the teaching mode of chemistry in middle schools has undergone great changes,and the way students learn has gradually changed from regular learning controlled by teachers to inquiry-based learning.In order to adapt to this change,some teaching modes were put forward.Among them,the case-guided mode has attracted the attention from teachers for the unique advantages in stimulating learning interest and promoting independent learning for students.Experimental teaching mode has always played an important role in the chemistry teaching,and the new experimental teaching based on case-guided mode can stimulate students' interest in learning,scientific learning method and improve problem solving ability.However,its implementation is closely related to the design and application of the tutorial.At present,most of the experimental tutorials written by many teachers mainly focus on the guidance of experimental operations,and are less designed for the cognitive ability of students and the needs of inquiry teaching.Therefore,most of the chemistry labs are neither conducive to the improvement of students' self-exploration ability,nor can they meet the requirements of the new curriculum standards to cultivate the core literacy of students' chemistry disciplines.The above-mentioned problems are deeply and systematically studied.Through the prophase research,using methods of literature,questionnaire and case study,the new curriculum reform under the background of learning design patterns of domestic and foreign research present situation,research the chemistry teachers' implementation of exploring experimental teaching and learning in the present situation of the design,put forward its own guiding case design method.This study divides learning under the background of new curriculum reform of junior middle school chemistry experiment in the teaching mode of the research into three parts,the concrete content is as follows:(1)Analyze the chemistry teaching content and target in junior middle school,including the analysis of textbook,the analysis of students' learning psychological characteristics,the analysis of three-dimensional teaching target,the analysis of teaching priorities and difficulties and the analysis of the teaching methods.(2)Design the chemistry experiment "guide case" teaching process in junior school,including teaching objectives,pre-class preparation,class implementation,teaching reflection.(3)Apply the teaching mode of experiment teaching in chemistry in junior school under the background of the new curriculum reform,and compare the teaching outcome with the class adopting the conventional teaching model,with the data analyzed.The results show that within the research scope of the junior high school chemistry surve y sample involved in this paper,most students' grade have improved after adopting the guided le arning plan teaching mode in the chemistry experimental class,especially the promotion for th e underachievers.Students' interest towards chemistry experimental course is greatly enhanced,which improves their participation in class.The student will actively preview the course cont ent according to the guided learning plan,which efficiently promotes the teaching progress in the classroom.Meanwhile,the guided learning plan has greatly improved the relationshi p between teachers and students.Teachers and students actively cooperate to complete the lear ning tasks together in class.
