The Application Of The View Of Energy And Balance In The Teaching Of "Principles Of Chemical Reaction"

High school chemistry is a key part of elementary science education,Curriculum standards make a clear request that the students can understand the chemical nature according to chemical definition and connotation and thus form the related scientific fundamental conception of chemistry,and teachers should deepen the curriculum resources,expand the space for students' development,and make the chemistry curriculum play a positive role in science education.Actually,in the course of teaching practice,it is found that the students in the region where the current situation of chemical learning and standard requirements there is a clear discrepancy.In this paper,according to the current situation of existence difference for clear requirements of curriculum standards and chemistry actual situation of teaching and learning in the area.Chemical Reaction Principle(Option 4 of PEP)is used as the teaching material,The relationship between chemistry concept and cognition,learning and teaching are explained.The author carefully study the teaching material of chemistry reaction principle and the curriculum standard of senior high school chemistry,and through the combing and summarizing of key knowledge,the idea of the textbook was focused on energy and balance,and two parallel classes are selected as the object of study,and the chemical reaction principle was chemically studied by contrasting the experimental class and control class.Basic concept of teaching and training application,and the results of a semester of teaching practice to academic achievement changes and changes in students thinking ability of two aspects of comparative analysis.The results of teaching practice show that the emphasis on the teaching of the students' view of energy and balance in the teaching of elective principle of chemistry teaching in the PEP has a definite influence on the students of the study,which is mainly reflected in the understanding of chemical knowledge,Chemistry learning interest,compared with the control class,experimental class students in these areas have some progress.This shows that the chemical teaching focused on the cultivationof chemical concepts,the author taught the object of thinking ability training and problem-solving ability to develop a certain degree of help,to promote the formation of these students basic concepts of chemistry.
