Teaching Research On The Introduction Of The Additive Experiment In The High School Chemistry Review Class

According to the curriculum standard,it usually takes three years to learn chemistry in high school,but in fact the last year is used to carry out a simple review.This in fact is not conducive to enhance the students' chemical literacy.At present,teachers usually take verification mode,learning plan teaching mode,micro thematic mode to organize chemistry teaching.Chemistry is a subject based on experiment,college entrance examination of chemistry experiment is also a key point,If you discard chemical experiments only for paper and pen review,students maybe give up chemistry learning.Introducing adjunction experiments in chemistry review class is an effective mode that includes reasonable and proper experiments to educate students to actively review old knowledge.Through adjunction experiments,students could be independent,effective and interested to complete the knowledge of the chemistry review of knowledge systematically and modularly,as result,adjunction experiments could improve the ability of students to learn effectively.This mode will review the above several commonly used mode integration and development,existing problems and guide the learning plan guidance,both micro and thematic knowledge verification.The key of this mode is to leading students to experience the reasonable experimental adjunction from dynamic dimension and static dimension to mobilize students' thinking and perception of all the senses,enhance the perceptual knowledge and review the students' interest.In this paper,it is comply with the requirements of the curriculum standards and the examination syllabus and the examination instructions,it is feasible to draw lessons from the teaching practice of teachers and to seek theoretical support from the related work of the experts and scholars in the experiment and teaching.Literature retrieval,teaching research,action research,tracking evaluation and student interviews and other methods are used.According to the review of the practice of chemistry teaching,the paper demonstrates the feasibility of the adjunction chemistry experiments from dimensions of teaching design,teaching process,teaching evaluation,teaching reflection and teaching tracking respectively with three specific examples of typical practice.
