The Development And Application Of "Dream Course" Based On The Scratch Class In Primary School

Computational thinking is considered by the Computer Science and Telecommunications Commission(CSTB)as the core competence of students in the 21 st century,and is listed as one of the four core literacy of the information technology discipline by China's "General High School Information Technology Curriculum Standards"(2017 edition).Scratch software is a programming software designed specifically for children,and is one of the preferred computing thinking training tools for everyone;the dream course is a comprehensive school-based course for the purpose of improving students' core literacy,and its teaching concepts can be integrated into Teaching in other disciplines.The information technology curriculum in elementary and middle schools is a basic approach to information technology education.It should conform to the characteristics of the times and assume the important task of developing students' computing thinking.This study takes Adream as a platform,under the guidance of primary and middle school information technology curriculum standards,dream curriculum teaching concepts,with the purpose of cultivating students' computational thinking,with education design research as the main research method to analyze,design,and develop in line with the recognition Scratch "Dream Course" textbook(school-based)that knows the rules and age characteristics,and is named "Hello,Scratch".Teaching practice for 3-5 grade students in the activities of elementary school information technology clubs.After multiple iterations of the educational design research model,the Scratch "Dream Course" teaching material and its development model and the evaluation model of student computing thinking are summarized and verified.effect.In the development of the "Dream Course" in "Hello,Scratch",first of all,the literature research method was used to sort out and summarize the research status of computational thinking,Scratch and Dream courses at home and abroad.And theoretical basis.Based on iterative analysis,design,development,practice,revision and other links,designed the flow chart of "Hello,Scratch" "Dream Course" textbook development,and completed three units(Hello,Scratch,Story,Game))A total of 17 hours of "Hello,Scratch" "Dream Course" teaching program and teaching resource library(supporting PPT,micro-class)production.In terms of application of teaching practice,students' independent learning and cooperative learning are the main forms of learning,combined with the teaching concept of the dream course,teaching is carried out according to the four links of "warm-up activities,theme activities,display sharing,evaluation summary".In the teaching process,driven by tasks,it focuses on cultivating students 'problem-solving ability,design thinking,abstract thinking,logical thinking,recursive thinking,and problem-solving ability to promote the improvement of students' computing thinking ability.According to the characteristics of computational thinking measurement,design a computational thinking evaluation system that emphasizes both process evaluation and summary evaluation,and evaluates the development of students' computational thinking ability from multiple dimensions.Finally,using the pre-test questionnaire data for calculating the thinking level as the pre-test data for the teaching,the classroom observation,student interviews and Dr.Scratch's work analysis as the process evaluation data,and the 34 effective samples of 6 effective works of Dr.The Scratch tool score is used as a summary evaluation data to verify the effectiveness and feasibility of the textbook.The results show that all the results of each class hour are all significant and have a positive correlation.The textbook "Hello,Scratch" "Dream Course" can promote the development of students' computing thinking ability.
