| In the crucial period of winning two hundred years and under the unique background of the dual era of the reform of college entrance examination,learning autonomy and high efficiency is still the focus of education and teaching practice.Because of the particularity of mathematics,it is more necessary for students to have a certain understanding of efficient autonomous learning methods.In the process of teaching,teachers should cultivate students’ autonomous learning ability and learning efficiency.Previous studies have proved that example learning is one of the ways to cultivate students’ autonomous learning and improve their learning efficiency.Sample learning is a learning and application process in which students discover problem-solving patterns,summarize general rules and can be used in specific applications by reading and thinking about examples under the original knowledge system.Through combing the previous research literature,the main research questions are determined as follows:(1)In junior high school mathematics learning,can the familiarity of learning domain knowledge have a positive impact on the learning of double-content sample?(2)In the two groups of subjects who are familiar with domain knowledge,will different interpretations have different learning effects?Firstly,according to the need and the existing theory,literature analysis method is used to consult,sort out and analyze the existing relevant literature,form a deep understanding of the research issues,determine the research ideas,design a single quadratic equation calculation questions and sales problems application questions,and modify and improve them with the advice of the instructor.Secondly,using the experimental method,the subjects in the first experiment are divided into familiar group and unfamiliar group and learn the same samples.In the second experiment,the subjects familiar with the learning area after the pretest learn the samples that cause self-explanatory problems,no self-explanatory problems and teaching explanations respectively,and investigate whether there is a significant difference in the post-test results.Finally,SPSS22.0 software is used to analyze the impact on students’ post-test scores.Through the experiment and using SPSS22.0 software to analyze the corresponding data,we draw the following conclusions:(1)In the dual-content sample learning,the far and near transfer performance of the subjects who are fully familiar with the learning domain knowledge is significantly better than that of the subjects who are not familiar with the learning domain knowledge.(2)In bi-content sample learning,the post-test proximity transfer performance of the self-explanation group was significantly better than that of the non-explanation group;the self-explanation group was significantly better than that of the teaching explanation group and the non-explanation group;there was no significant difference between the self-explanation group and the teaching explanation group in proximity transfer performance.Based on the research results and conclusions,the following teaching suggestions are put forward:(1)the design of examples should take full account of the students’ existing knowledge and pay attention to the students’ "recent development zone";(2)the combination of teacher guidance and student cooperation is needed in students’autonomous learning to stimulate students’learning drive;(3)first learning and then teaching,Teaching according to learning,to improve the effect of sample teaching;... |
