| The way of education was greatly influenced because of the rapid development of information technology.How to implement teaching reform to prove teaching efficiency under the two-way impact of epidemic situation and information.Hydrocarbon derivatives are not only the important content and core knowledge of high school organic chemistry,but also the difficult point for students.In this paper,the "derivative of hydrocarbon" is chosen as the research object.The effective combination of various teaching approaches and strategies is adopted to construct a diversified teaching model base on the theory of learning progression.These will provide teaching ideas for the teaching of hydrocarbon derivatives.The paper is divided into sixth parts:The first part is introduction.This part explains the background of the research,research purpose and significance,the status of research domestic and overseas.The second part is theoretical basis and conceptual definition.This section explains the meaning and theoretical basis of related concepts.The third part is the questionnaire survey.This part carries on the questionnaire investigation and analysis of the high school science class studying “The hydrocarbon derivative”.These results will provide important support for the establishment of progressive diversified teaching model.The fourth part is construction of a diversified teaching model based on the study of the advanced “Derivatives of hydrocarbons”.The appropriate teaching approaches and teaching strategies are selected to construct a diversified teaching model according to the existing research,the curriculum standards,the results of questionnaire survey,and student requirements at all levels.The fifth part is teaching design and implementation.The carboxylic acid and its derivatives in "Derivatives of hydrocarbons" is selected for teaching design on the basis of the characteristics of teaching content,the law of students’ cognitive development and the strategy of diversified teaching mode.The sixth part is conclusion and prospect.The conclusion is obtained according to the results of experimental class and control class before and after the implementation of teaching.And the problems in the implementation of the research are summarized to provide ideas for future front-line teachers in the teaching design of “Hydrocarbon Derivatives”. |
