Practical Research On The Application Of Mind Maps To Promote High School Students' Core Competences On "Macro-Recognition And Micro-Analysis"

With the progress of the college entrance examination and the reform of high school chemistry teaching,it is required that the teaching should change from the traditional "knowledge conception" to the "quality orientation",and the core values of chemistry should be taken as the guidance,relying on the necessary knowledge and taking the key abilities as the starting point,so as to cultivate students' core quality of chemistry discipline.The accomplishment of "macroscopic identification and microscopic analysis" is the first accomplishment,which reflects the discipline concept and unique thinking mode of chemistry.Structuralization of the necessary chemistry knowledge in high school is the basis of cultivating the core chemistry accomplishment,and mind mapping is a non-linear thinking representation tool with pictures and pictures,which can structure and visualize the complex chemistry knowledge in high school,so that students can better master the necessary knowledge.To explore application of mind mapping promote the validity of high school chemistry core accomplishment by literature study and put forward applying mind mapping to cultivate high school students' identification of macro and micro analysis "literacy teaching strategy,select the element and its compounds research content for the teaching,teaching case design,to carry out the education experiment research;Exam tests hand draw a mind map,students and students interview three aspects detection practice,using the SPSS data analysis software is analyzed,the result of the test results show that the experimental class scores and literacy level is better than that in comparative classes,and two classes of literacy development gap is widening,application of mind mapping to help high school students' identification of macro and micro analysis " literacy cultivation;According to the analysis of student interviews and mind maps drawn by students,the application of mind maps is also conducive to improving students' summarizing ability and thinking ability,changing students' learning styles,and contributing to teachers' professional growth.The specific work is as follows:(1)This paper expounds the research background and current situation of using mind mapping to promote the cultivation of high school students' core quality of chemistry discipline,defines the three core concepts of mind mapping,core quality of chemistry and "macro identification and micro analysis",and discusses the theoretical basis of the research and its enlightenment to teaching.(2)Through the analysis of the mid-term examination of science classes in Senior Three,the experimental class and the control class were determined,the questionnaire was prepared and the quality was analyzed by SPSS software,and the cognition and application of the tool of mind mapping in the two classes were understood through the questionnaire.(3)Combined with the students' actual situation to determine the teaching research content-Elements and Their Compounds as an example,at the same time,put forward the application of mind mapping to promote the high school students' "macro identification and micro analysis" literacy teaching strategies,determine the teaching mode.(4)According to the strategies and teaching mode,the properties of the metal sodium,second class of the nature of the chlorine and "iron and its compounds 2 class 3 case teaching design,and used in teaching practice,according to the teaching strategy put forward the evaluation criteria of core literacy training system,preparation of test and interview outline,using SPSS software to detect the quality of test,analysis of each level of the students' problem solving situation,at the same time undertake to the student interviews,to understand the effectiveness of teaching strategies.
