Research On The Optimization Of High School Chemistry Homework

In the current high school chemistry teaching,the teacher's goal of designing homework is to consolidate and master the classroom teaching content.As a result,most of the assigned homework is written,lacking open,practical and inquiry-based chemistry questions,and almost no real-life or interesting questions.The overall number of questions and assignments is slightly more,and it is not very targeted.This kind of chemical homework design is contrary to the core competence and moral education.Homework is an important way to develop the core accomplishment of high school students.It is necessary to conduct research.Based on the current literature,this thesis compiles a questionnaire for the current status of high school chemistry assignments from five aspects: the number,difficulty,type of chemistry assignments,and satisfaction with chemistry assignments.Through this questionnaire,a sample survey of 225 senior students of the middle school of the author's internship school Z Middle School was conducted to investigate the current situation of high school chemistry homework in the middle school.At the same time,an interview question was designed to interview the teachers in the first grade group and other representative teachers in the school.It explores teachers 'opinions on the current arrangement of chemistry assignments,types of assignments,number of difficulties,etc.,as well as the development of students' core academic literacy through chemistry assignments.The survey concluded that the current difficulty and quantity of chemistry assignments in Z Middle School are basically in line with the idea of reducing the burden on primary and secondary schools;students like rich types of chemistry assignments but the current types are relatively single;students' interest in chemistry is not strong enough,so it is necessary to stimulate students' interest.According to the current situation of the survey,while drawing on the research results of chemical operation reforms at home and abroad,a thinking framework of operation optimization based on discipline core literacy,teacher's subject comprehension and students' learning was constructed.Based on this optimization framework,the school's supporting exercise book and the current teaching content,the chemistry tasks were optimized.In Z Middle School,two classes with similar overall level were selected as control class and experimental class.The experimental class used the optimized chemistry work based onthe optimized thinking framework,and the control class' work remained unchanged for a28-day practical study.Using the Chinese version of SPSS22.0 software to compare and analyze the results of the control class and the experimental class.After the experiment,a questionnaire was prepared to investigate the students in the experimental class,and some representative students were selected for interviews.The comprehensive analysis concludes that based on this optimization framework,it can develop students' subject core literacy to a certain extent,stimulate students' interest in chemistry subjects,and significantly improve students' chemistry performance.
