Research On Differentiated Instructional Design Based On Scratch's Expansion Course

Under the background of information era,it is particularly important for students to improve their information literacy and information ability,and cultivate their awareness and interest in information technology.Scratch curriculum has gradually entered the classroom of primary school,Due to the large difference of students,traditional teaching design has been unable to meet their learning needs.The article mainly from the perspective of students,teaching philosophy in difference under the guidance of individual differences.based on the students,designs the teaching goal based on the hierarchy,the teaching content of independent choice,the flexible and dynamic learning organization,and the open and free inquiry learning atmosphere,so as to let every student get better development.The article is mainly from the teaching practice in teaching practice as a starting point,access to relevant information to solve problems.The author finds that the students’ learning background,learning ability,learning level and learning demand are different in the scratch development course.The traditional teaching methods can not meet the students’ learning needs.The author finds out that differentiation teaching can solve the problem of teaching,and then puts forward the research of differential teaching design based on scratch extension course.Differentiated instructional design is based on students’ individual differences and needs to do well in the diagnosis and analysis of learners.The author uses observation,questionnaire and work analysis to diagnose and analyze students’ learning attitude,learning habits,learning behavior and learning needs.In order to better carry on the differential teaching design of the scratch development course,the author uses the literature analysis method to analyze the course of scratch,and puts forward the feasibility of the differential teaching in the application of the scratch development course.The difference teaching and scratch course are combined,and the design of different teaching objectives,teaching content design,teaching organization form design,learning environment design and diversified teaching evaluation design based on scratch extension course are put forward.In order to verify the effect of differential teaching design,the author takes the "happy bird" project as an example to implement the differential teaching design based on the scratch extension course.In the process of implementation,the author modifies and perfected the teaching design.Again,thepractice of the "snake" project is carried out to verify the effect of the differential teaching.
