There is no doubt that grammar teaching is of vital importance in high school English teaching.However,some teachers have been unable to fully arouse students’ enthusiasm in learning by “explanation of rules first,then consolidation of exercises” when teaching English grammar,and the situation that some teachers dominate the class all the time influences the cultivation of students’ independent learning ability and motivation of learning interest,which leads to the effect of teaching is not very ideal.Combined with context theory,teachers can create reasonable and interesting language learning environment,helping students enhance their interest in learning and make students participate in learning and discussion actively,which can help students master and apply the knowledge they have learned better,improve their learning efficiency.Although there are lots of researches about context theory,the researches combined with modal verb can’t be found easily.While the form of modal verb is simple,the usage is more complex,and the effect of students’ grasp of its meaning is also not satisfactory.So the thesis attempts to combine context theory with English modal verb teaching in high school and discusses teaching effect through case analysis.Based on this background,this thesis studies the context theory and analyzes the teaching cases of English modal verb teaching in high school from three aspects: presentation,practice and production.Through the methods of observation,interview and case analysis,this thesis discusses the process and effect in English modal verb teaching,and puts forward the corresponding teaching suggestions according to the problems in teaching.With the support of the context theory,it can be seen by case analysis: the use of contextual teaching method can achieve good effect in high school English modal verb teaching.The purpose of this thesis is to explore the feasibility and effectiveness of contextual teaching method in high school English modal verb teaching,and hope that the thesis can provide more valuable references for future teaching practice. |
