High School Chemistry Teaching Research Based On The New Concept Of Evaluation

Evaluation reform is an important part of curriculum reform.According to the chemistry curriculum standard of senior high school(2017 Edition),chemistry learning evaluation is an important part of chemistry teaching evaluation.It has the function of diagnosis and development for students' chemistry core accomplishment.It advocates the combination of daily learning evaluation and achievement evaluation of chemistry,and pays attention to the organic combination of process evaluation and result evaluation.At present,high school chemistry is in the initial stage of the implementation of the new curriculum.It is an important task to carry out teaching practice research on the basis of understanding the new concept of evaluation,so as to promote the process of curriculum reform.Using the new concept of evaluation to guide the teaching process can not only explore the application of the new concept of evaluation,but also explore the diagnostic method of the implementation of core literacy.First of all,combined with the analysis of relevant literature,the paper interprets the chemistry curriculum standard of general high school(2017 Edition).The evaluation concept of the new curriculum is mainly reflected in three aspects:evaluation standardization,situational teaching,"teaching,learning and evaluation" integration.The connotation of the three new concepts is analyzed from the perspective of implementing core literacy,and reasonable teaching mode and teaching strategy are selected to establish theoretical guidance basis for teaching practice research.The results show that the new curriculum evaluation concept has a very important guiding significance for the implementation of core literacy and the realization of daily evaluation.Secondly,according to the new concept of evaluation,the teaching content "iron and its compounds" is selected for teaching design.Taking the reverse teaching design as the model,the new idea of evaluation is permeated into the daily teaching.The new idea of evaluation runs through the whole teaching process,and the possibility of applying the new idea of evaluation to teaching is explored.The research results show that it is feasible to evaluate the new concept to guide the teaching design with multiple evaluation methods in combination with specific teaching contents.Finally,the teaching design will be carried out in classroom teaching practice and after-school teaching evaluation,the teaching process will be analyzed,the teaching results will be evaluated through exercises,and the teaching practice will be diagnosed through teacher interviews.The results show that the new concept of evaluation is embodied in the teaching process,and the implementation of core literacy is good.
