| Since the implementation of "double reduction" policy,"homework problem" has once again become the focus of hot discussion in the educational circle.As the intersection of teaching and learning,the effective implementation of homework is one of the key links to achieve "reducing the burden" and "enhancing the efficiency".Because of its high abstractness,mathematics discipline pays special attention to students’ homework training.High school mathematics curriculum is difficult and homework burden is heavy.How to guarantee the effectiveness of high school mathematics homework has attracted many mathematics educators to carry out research on it.However,most of the existing achievements point to the design of high school math homework,homework correction and homework evaluation have been neglected.Based on this,this paper tries to study the problem of Grade one math homework correction and appraisal,investigate the current situation of grade one math homework correction and appraisal,and explore the effective strategies of grade one math homework correction and appraisal.First of all,through the analysis of homework text and questionnaire survey,this paper concludes that there are four problems in the correction of math homework in senior high school:(1)the marking symbols are monotonous,and the teachers’ humanistic care is not in place;(2)Lack of correction and comments,the emotional bond between teachers and students is not strong;(3)The correcting method is single and the communication path between teachers and students is not smooth;(4)operation correction is lax,correction and evaluation quality is not guaranteed;In the questionnaire survey,it is found that there are three problems in mathematics homework evaluation of senior one:(1)The few times of evaluation,the accumulation of problem knowledge is not easy to solve;(2)Outdated way of evaluation,students thinking enthusiasm is difficult to glow;(3)The lecture class is boring and the effect of difficult to solve doubts is not significant.Secondly,in view of the above problems,following solutions are put forward: In the homework correction,(1)introduce new symbols;(2)Leave a brief comment;(3)Implement the plan for face approval;(4)carry out the second correction;On homework evaluation:(1)Encourage students to give comments;(2)One problem with multiple solutions;(3)concentrate on the same type;(4)Variable expansion;(5)Integrate into the mathematical culture.Finally,the above mentioned strategies are applied to the daily math homework correction and comment of senior one students.Three students are selected for case tracking investigation,the implementation of each strategy is presented with examples,and the performance of the three students in math homework and homework lecture and evaluation is recorded in detail.After the teaching practice,the three case study subjects were interviewed to understand the students’ views on the strategies used.At the same time,interviews were conducted with the classmates and math teachers of the research subjects to fully understand the changes of the three case study subjects in math homework,math scores and math learning attitude before and after using the proposed strategies.Combined with the "three being" theory of economics,the "effectiveness" of the proposed strategies was demonstrated from the three aspects of "efficiency","effect" and "benefit". |
