The Design Of Science Micro Course In Primary School Which Tends To Core Ideal

Micro curriculum is a new learning method which can support the unconstrained learning time and place.It is a hot topic of mobile learning and network learning.It is also one of the important means to realize the change of students' learning style and teachers' teaching style.In February 2017,China promulgated a new edition of the "Compulsory Education Primary Science Curriculum Standards",in four areas a total of 18 core concepts were selected as the content of primary science curriculum.According to these core concepts,it has very strong practical and practical significance to study the micro-curriculum design of primary school science.The research starts from the research status at home and abroad.Through combing and analyzing the relevant research on micro-curriculum and core concepts,the micro-curriculum and core concepts in this study are defined.Determine the theoretical foundation of the micro curriculum.A comparative study is conducted on the websites of micro curriculum resources with certain influence.The characteristics of micro courses on these websites are analyzed to provide reference for subsequent micro curriculum design.On the basis of previous work,we construct a design framework of primary science micro curriculum which tends to the core concept.Put forward the design concept,design principles and design process.Under the guidance of the design framework,the important optical concepts in primary school science education are selected to carry out the practical research on the design of the special micro-course of Light and Life.It also invites front-line excellent science teachers and teaching and research staff to evaluate and grade according to the micro curriculum evaluation indicators.To further verify the rationality and practicability of micro-curriculum design,a questionnaire on the design and development of micro-curriculum in Light and Life was compiled.The first line of outstanding science teachers and teaching and research staff are released and recycled.SPSS software is used to analyze data and draw conclusions.The results show that the average score of the micro-course of "Light and Life" is 90.3(full score is 100).It has gained a high level of evaluation from first-line excellent science teachers and teaching and research staff.The questionnaire compiled by this study has high reliability and validity.Most of the respondents believed that thematic micro-courses were more conducive to the formation of a complete knowledge structure than scattered micro-courses.The content of courses can be arranged according to the development of scientific concepts.It also shows strong willingness to use this kind of micro curriculum resources.
