Research On The Design And Practice Of Micro-topic Teaching Of Junior Middle School Mathematics Supported By Information Technolog

With the development of social informatization and the deepening of new curriculum reform,teachers need to change their teaching methods to meet the needs of modern education.In order to promote students’ deep learning and adapt to the characteristics of narrow attention and short stable time of junior high school students,junior high school mathematics needs to carry out micro-thematic teaching.However,there are some more abstract knowledge and micro-thematic teaching in mathematics,which is easy to lead to scattered knowledge problems.The micro-thematic teaching of mathematics in junior high school needs the support of information technology.However,through the conversation and practical observation with the front-line teachers,the author found that the front-line junior high school mathematics teachers,the author found that the front-line junior high school mathematics teachers were confused in the design of information technology support micro-thematic teaching.Some teachers did not know the internal connection between the support role of information technology and the junior high school mathematics micro-thematic teaching,and did not know how to better integrate information technology The micro-topic teaching of junior high school mathematics is effectively combined.At the same time,through the retrieval of literature,the author found that there are relatively few junior high school mathematics micro-topic teaching and practical research on information technology support.Based on this,the author wants to study the design and practice of junior high school mathematics micro-topic teaching with information technology support.The author mainly uses the literature research method,investigation and research method,classroom observation method and quasi-experimental research method to conduct research.First,he reads the literature to determine the topics and assumptions,and then uses the survey method to distribute questionnaires and interviews to teachers and students.After obtaining the real data,he collates out the data analysis of the current mathematics teaching situation On this basis,the junior high school mathematics micro-thematic teaching supported by information technology is designed,and the principles and processes of the junior high school mathematics micro-thematic teaching design supported by information technology are summarized.The teaching principles are mainly the principle of micro-thematic teaching capacity and student ability adaptability,the principle of micro-thematic teaching design variable flexibility,and micro-Teaching design should reasonably give full play to the principle of the support role of information technology and the principle of combining micro-thematic teaching with conventional teaching,carry out micro-thematic teaching or conventional teaching after preliminary analysis according to the teaching principles,and give due play to the supporting role of information technology in the teaching process.In the process of practice,micro-thematic teaching is carried out in the experimental class,and the parallel class is routinely taught.After practice,the before and after the data are compared with the parallel class data of the experimental class,and the conclusion of this research is finally reached.After the junior high school mathematics micro-thematic teaching design and practice of information technology support,the author used SPSS and Excel software to compare and analyze the questionnaire data before and after teaching,and interviewed students.Combined with the author’s observation of classroom behavior,the following conclusions can be clearly drawn.After the junior high school mathematics micro-thematic teaching supported by information technology,students think that learning mathematics is an interesting thing.They are willing to learn mathematics and think that the difficulty of learning mathematics is reduced,and their performance in the classroom has also become better.The classroom atmosphere is active.Students’ level of deep learning is improved,and they will think with mathematical thinking.Real life shows that students’ ability and literacy in learning mathematics have been greatly improved.Finally,the author reflected on the micro-thematic teaching process of junior high school mathematics with information technical support,and summarized the relevant precautions of junior high school mathematics micro-thematic teaching with information technical support.The main reason is that teachers should carefully select the micro-thematic teaching content,grasp the relationship between micro and professional,preview micro-video to appropriately reduce the difficulty,and Xi’s interest,teachers should urge students to learn independently,and test the results in the classroom.Teachers should pay attention to the status of students in the classroom,and pay attention to maintaining classroom order while giving encouragement.I hope to provide some references to front-line teachers.
