Investigation And Improvement Strategy Of High School Physics Group Experiment

Group experiment is an important category of physics experiments in senior high school;they are helpful to cultivate students’ scientific spirit,practical innovation and other core competences in the process of experiment teaching.However,the effect of group experiment teaching in high school is not satisfactory currently.In this thesis we chose five high schools in Zhejiang Province as research subjects,and conducted interviews and questionnaires to investigate and analyze the current situation of physics group experiment teaching.The result shows that there are many problems in group experiment teaching in high school:(1)In preparation stage: lack of professional experimenters,insufficient preparation by students;inadequate class hours;monotonous forms of group experiments;(2)In experiment stage: students’ inquiry ability is generally not strong;experiment teaching form is monotonous;inquiry situation creation is difficult;(3)In summary and evaluation stage: evaluation method is monotonous;evaluation content is not comprehensive.Based on the problems existing in group experiment teaching,this thesis puts forward the following teaching strategies:(1)In preparation stage: fully understanding the importance of the experiment;making every effort to improve the equipments of laboratory;making full preparations before the experiment;using mobile grouping and approximate grouping methods;(2)In experiment stage: setting "problem chain" to induce the experiment;innovating the experimental mode to enhance students’ ability;inspecting and helping students during the experiment;(3)In summary and evaluation stage: reviewing the experiment process,reflecting on "teaching" and "learning";enriching the evaluation forms and evaluating students comprehensively.In the final part of this thesis,we presented some specific group experiment teaching cases and classroom records.
