| In the digital era,more and more requirements have been put forward for the digital literacy of talents from all walks of life,and courses have always been the main channel for cultivating students’ digital literacy.Looking at the more than 30 years of information technology courses in China,from the traditional teacher-based teaching mode to the current prevailing blended teaching model to promote students to learn better,from the iterative update of new and old course standards of information technology courses,it can be managed to improve the classroom teaching quality of information technology courses in Leopard’s middle school.However,at the time of the alternation of new and old curriculum standards,the teaching of information technology courses in secondary schools faces the following problems:(1)shortage of high-quality digital teaching resources for information technology courses;(2)The classroom teaching method is relatively simple and teaching-oriented;(3)The quality of classroom teaching needs to be improved;(4)In classroom teaching,there is less improvement and cultivation of students’ independent learning ability.If the above problems are solved,it will be beneficial to the cultivation of digital literacy of talents in the information age.In order to improve the classroom teaching quality of the blended teaching of secondary information technology courses,the author embedded the PDCA quality loop of the idea of total quality management proposed by Dr.Deming in the information technology teaching practice,built a blended teaching mode based on the PDCA quality loop,and integrated the four stages of P(plan),D(execution),C(inspection)and A(processing)in the PDCA quality loop into classroom teaching under the guiding ideology of the new curriculum standard.Implement the full participation of all students in the whole classroom teaching,and implement the whole process management and monitoring of the classroom,in order to continuously improve and perfect the classroom teaching in the teaching cycle,and finally improve the participation of students in the information technology classroom teaching and achieve the improvement of student performance.This study is divided into five parts: the first part is to sort out and analyze the relevant literature through the literature research method,and then summarize the connotation and blended teaching principle of PDCA quality loop,clarify the research background,research status and shortcomings in the research,and point out the new research content and research plan;In the second part,the teaching status,teaching objectives and learning objects of secondary school information technology courses are analyzed,and the necessity of PDCA blended teaching is explored.The third part is to design the teaching mode of secondary school information technology course based on PDCA quality ring on this basis;The fourth part,using the quasi-experimental research method,in the eighth grade information technology course of middle school,through the content of the two courses of “data cleaning” and “data visualization” to carry out the experimental research of “hybrid teaching based on PDCA quality loop”,after the first experimental teaching,the successful experience is solidified,the problems that cannot be solved in the PDCA quality loop are improved and perfected,and the content of the second lesson is practiced,modified and perfected again;In the fifth part,the survey and research method is used to analyze the improvement of students’ learning participation in classroom teaching,and the monthly examination results and student satisfaction ratio of practical teaching in experimental and control classes are compared and analyzed horizontally,and then verify that the PDCA blended teaching mode can help improve students’ participation and academic performance in classroom teaching.This teaching practice can be used as an effective supplement to the new teaching mode under the new course standard. |
