| Primary school science curriculum to train students'scientific literacy and problem-solving skills as the goal of scientific enlightenment courses, and its content has a certain abstraction.lf not preparation and rehearsal before class, the students will lead to understand course content difficultly, and class participation decreased.Therefore, scientific and effective preparation, can enhance students'interest in science, to improve the efficiency of classroom inquiry, and science and technology has been an important means of promoting the educational reform.This study analyzes the status and related theoretical research of rehearsal in primary science curriculum, analyze problems in the classroom. And research QR code technology in the field of educational applications, summarized the QR code technology has features and advantages for learning activities,and the integration of primary school science prep work will be explored.This study selectedtwo parts of sixth grade science textbooks for the study topics, according to the general principles and methods of rehearsal, give full play to the advantages of QR code technology, from two directions to explore the abstract theoretical knowledge and experimental knowledge were analyzed based on QR code technology preview activities on classroom learning.The results show that by learning a single QR code preview for technical support, help to stimulate students' interest and maintain a positive motivation to learn; through classroom observations, student enthusiasm in the classroom significantly increased; a QR code technology for application in a single prep the students have a higher degree of acceptance and satisfaction.In this study, the primary science enrich learning preview forms and methods, to a certain extent on the primary science prep work to improve and enrich the resources of practical significance, provides a new idea for the two-dimensional code technology in the field of education. |
