On 3D Printing Teaching Design And Practice Of Science Course In Middle School

With the rapid development of modern science and technology,the value of science education to the country and society is self-evident.As a course reflecting the essence of science,science curriculum in middle schools in China should be based on the development of students and guide them to understand the essence of science.However,due to the lack of teaching materials and practical guidance,science literacy education mostly stays in empty slogans and empty forms.As a good carrier of science and technology and comprehensive practice course,3D printing provides a new way of thinking for Science Education in middle schools.Based on constructivism learning theory and 5W communication theory,this research adopts the methods of literature research,questionnaire survey and design-based research to carry out the teaching design and Practice Research of H middle school science course.The teaching design of this study is based on the investigation of the current situation of science teaching in H middle school.The pre-test questionnaire is used to investigate and analyze the teaching objects.The three-dimensional teaching objectives are determined according to the curriculum outline of Science in our middle school.The theme of teaching content is designed according to the characteristics of 3D printing technology,and the teaching evaluation is determined from two aspects of content and method.After one month's teaching practice in H Middle School,the comparison of questionnaire data before and after the test,the analysis of students' works and classroom observation scale show that the teaching objectives of this study are basically achieved,the teaching effect is better,and the students' interest in science is obviously improved.However,the differences of students' learning ability,teaching environment and equipment also lead to the insufficiency of teaching effect.Based on the merits and shortcomings of the teaching practice process,in order to improve the teaching effect better,we should reduce the difficulty of the subject,improve the teaching content,enrich the learning methods and improve the teaching activities,pay attention to process evaluation and design activity report forms to improve the teaching design,so as to form a set of systematic and comprehensive teaching design cases,in order to fill in the current scientific teaching research in middle schools.Lack of specific teaching design and practice gaps.
