| The Covid-19 epidemic has set off a large-scale experiment of online education all over the world."Internet+education" has become a trend,and "Online education with suspension classes" has become the main teaching method in primary and secondary schools and universities across the country,which has alleviated the current situation of students' academic shelving during the epidemic to some extent.The online+offline blended teaching mode may become a new teaching form.By consulting the related literature of blended teaching,it is found that blended teaching has the advantages of online teaching and offline traditional classroom teaching.However,there are few specific teaching applications of the blended teaching mode.The teaching effect,teaching methods,and teaching design under this mode lack data analysis and demonstration and actual case support.There are many practical researches on the application of Pad teaching in a single subject,and there are few comprehensive subject curriculum researches that include multiple subjects.Junior high school science in Zhejiang Province is a comprehensive science course.The author explores the feasibility of combining blended teaching and Pad teaching,and constructs a blended teaching model based on Pad,which has theoretical and practical significance.The author designed the teaching process based on the Pad-based hybrid teaching model,including the pre-class preparation stage-online teaching resource development,classroom teaching stage-online intelligent feedback under the line of interactive teaching,post-class consolidation stage-online consolidation There are three stages of practice communication and timely feedback.This thesis conducts case design and practical research in a comprehensive junior high school science curriculum,and selects the "acidity and alkalinity of substances" in the chemistry part,the simple machinery "the application of levers" in the physics part,and the "food digestion" in the biology part.And each lesson includes front-end analysis;the design of teaching specific implementation links;teaching reflection and other links.Taking the teaching case "Leverage Application" as an example,the specific links of the teaching model are designed according to the functional application of Pad,including pre-class teaching preparation and face-to-face classroom teaching through the online and offline link cloud classroom function.After class,the cloud homework function of the teaching base is used to publish resources after class,and the interesting study boat allows students to review and consolidate and improve after class.In teaching practice,the conclusion is made through analysis of student performance,classroom teaching structure analysis,and student performance analysis.In Pad-based blended teaching,the order of teaching structure and time allocation in the classroom have changed.When using Pad to enter the classroom teaching,it changes the distribution structure of classroom time,and also affects the time and way of teacher-student interaction.Compared with the traditional classroom,the time for teacher-student communication and student-student communication and feedback to students has increased,the time for feedback and evaluation has increased significantly,the time for teachers' personal lectures has been significantly reduced,students' interest in learning,enthusiasm for learning,and learning efficiency have increased.The three advantages of the Pad-based hybrid teaching model: First,it combines traditional classroom teaching with Pad mobile learning;second,teaching efficiency based on the analysis technology of the Pad platform and individualized cultivation of students;third,formal learning and informal learning are combined with each other..The author proposes six teaching strategies based on the Pad-based blended teaching model: goal-oriented strategy,dual teaching strategy,resource interest strategy,teaching overall integration strategy,interactive diversification strategy,and timely feedback strategy. |
