| At the beginning of 2020,the new type of coronavirus pneumonia ravaged the land of China and soon swept the world.Under such an epidemic,many schools have chosen to teach online.Some teachers prepare lessons at home and teach students what they have learned in the form of live broadcasts,and some teachers According to the original classroom process of face-to-face teaching,the content of the class was recorded as a video in advance and sent to the classmates to watch and study at home.This online teaching model is not a product of the epidemic,but the rapid development of science and technology has made education easier and more convenient to attend classes.However,it does not have much room for survival under the rule of traditional education.Classmates regard online classes as after-school tutoring.Last year,due to the impact of the epidemic,it speeded up its pace into every student's home.Under the policy of “stopping classes without stopping”,online classes became the most important learning for students.way.However,without the supervision and management of teachers,the teaching effect of online courses is worthy of our deep consideration,and how to improve the teaching effect of online courses is worth exploring.In the process of writing the thesis,the author consulted a large number of documents on online teaching strategies,extracted and interpreted these Chinese and foreign documents,and established that this article takes "online teaching strategies" as the research object,and "straight line and plane are parallel" in high school mathematics.The content of one section is a case study.The author analyzes and interprets the knowledge points of the textbook one by one,and compiles teaching plans suitable for online teaching.Then,I interviewed three teachers of different teaching ages in a middle school in Beizhen City,and analyzed the results of the interviews.Find out the difficulties encountered by the three teachers in online teaching,how to improve the efficiency of online teaching,etc.Secondly,design a questionnaire,randomly distribute it to 100 students,conduct a questionnaire survey,and test the reliability and validity of the survey results.To explore the effects of students' online learning and the factors affecting learning effects,and analyze the advantages and disadvantages of online teaching.Finally,a total of 200 high school students enrolled in 2019 and high school students enrolled in 2020 were randomly selected for comparison.In the experiment,the results of the experiment were imported into SPSS and Excel,and the mean and variance of the two grades of students' performance were compared.Using the T test analysis,it can be seen that the effect of online teaching is far inferior to that of traditional teaching.Based on the comprehensive analysis of teacher interviews and student questionnaires,the author finally came up with strategies suitable for online teaching:(1)Interest is the best teacher;(2)Adopt reasonable and effective teaching methods,infiltrate mathematics thinking,and improve mathematics literacy;(3)Focus on problem-type training and teaching Problem-solving skills;(4)Reasonable teaching design. |
