The Research On The Application Of Heuristic Science Writing Strategy In Chemistry Concept Teaching In Middle School

Chemical education is an important component part of education,science and chemistry concept learning is the foundation of chemical knowledge,is also a important branch of chemistry curriculum content,constitute the basic chemical knowledge "skeleton",is a difficult point in chemistry teaching in middle schools.The ability of students to understand and construct chemical concepts correctly is equivalent to half the success of chemical learning.However,through the research,it is found that both the students' concept learning style and the teacher's choice and application of the concept teaching strategy are deficient.And the domestic and foreign scholars believe that heuristic teaching science writing strategy is an effective concept transformation strategy,heuristic science writing to undergo the initial ideas,assumptions,observation,reasoning,prove,read more,the process of reflection,and the concept of learning should be obedient children thinking cognitive point of view is consistent.This research in the related information of heuristic science writing strategy and concept teaching,on the basis of the collection,sorting and analyzing in the ninth grade chemistry concept teaching,heuristic teaching science writing method in order to study its influence on student's concept learning.Choose two parallel class nine grade as the research object,the object of study is divided into experimental class and that in comparative classes,experimental classes implement the heuristic teaching methods,science writing that in comparative classes implement the concept of conventional teaching methods.Questionnaire survey was conducted,the experimental class students,understand students' opinions or Suggestions to the method of heuristic teaching science writing,after the experiment in two classes,compare two class concept transformation,to explore the influence of the teaching methods on students' conceptual change.The results showed that the students in the experimental class were significantly higher than the control class,while the students were more approbated to the teaching method of heuristic science writing.It is suggested that the heuristic scientific writing strategy can improve students' understanding of chemical concepts and significantly promote the transformation of students' chemical concepts.
