Qualitative Application Evaluations Of Teaching Strategies Of Chemistry Experiments For High School

The research content of this thesis is how to evaluate the using effect of teaching strategies in high school chemical experiment teaching,that bases on the condition of the complete of the “process and method” objective,when new curriculum reform has been carried out several years latter.In the sphere of literature review,first of all,this thesis summarized the definition and function of teaching strategies,and also made a summary about the significance,the classification and the research status of high school chemistry experiment teaching strategies.Moreover,the definition,significance and the research status of the assessment of classroom teaching were summarized by searching literature.Furthermore,it is also included in this paper that is the search result about the research status of the assessment of effectiveness of the “process and method” objective.Eventually,The definition of "process and method" objective also has carried on the summary.Literature review shows that The study of high school chemistry experiment teaching strategy is more widely,however,the targeted teaching strategy for classroom teaching evaluation system is ignored.Based on this,the thesis mainly work as follows.(1)Observe the scale for high school chemistry experiment teaching strategies to make classroom observe in view of the high school chemistry experiment teaching strategy.Observation results show that types of the chemical experimental teaching strategy are used unbalanced.And the same strategy used by different teachers,effect of the difference is very big.We need to establish a evaluation system for teachers to provide effective usage and evaluation method.(2)According to the theory of classroom observations and existing research,the chemical experiment teaching strategy evaluation system was formulated that based on "process and method" objective implementation effect.And according to the actual situation,we formulated a rating scale.Then by applying the evaluation system and scale,we evaluated the real high school chemistry experiment teaching,andreflections on the evaluation was carried out.(3)Taking “Strong electrolyte and Weak electrolyte” of Principle of Chemical Reaction for example,According to the result of classroom observation and evaluation,the corresponding teaching case was designed by using chemical experiment teaching strategy.
