Research On The Design Of Astronomical Practice In Middle School Base On Geographical Core

With the deepening of basic education reform,the cultivation of students' core literacy has become a consensus.Geography as one of the secondary school curriculum,its core accomplishment has become a common problem faced by all geography educators.The teaching of the way of practical activities is an indispensable teaching method to meet the requirements of the new curriculum reform.It is an important part of modern teaching,and it plays an important role in the cultivation of students 'subject accomplishment.The development of geography practice will be beneficial to the cultivation of students' core competence.To some certain extent,it is also necessary to enrich and cultivate students' geographical core literacy and to provide a new perspective for the cultivation of core culture in order to meet the needs of astronomical teaching in the middle school stage.Based on the practical activity teaching theory,the theory of geographical core literacy and the theory of constructivism learning,this paper studies the design of astronomical practice in middle school through literature research,questionnaire,observation and case study.First of all,through the questionnaire survey we know the weakness of middle school students' core competence,there's few geography practice activities,and lack of targeted design resources whereas large demand for teaching,so it has realistic needs to do practice design research based on the core competence of high school.Secondly,the explore of the core competence and astronomical practice,expand the connotation of the core competence in the perspective of astronomical practice,and make clear that the practice of astronomy has the training effect of comprehensive thinking,the cultivation of regional cognition,the extension of the concept of coordination between man and land and the promotion of geographical practice.Thirdly,we construct the middle school astronomical practice system from three aspects: the activity content,the activity object and the activity form,and construct the content of the activity within and outside the system and thecorresponding fixed and non-fixed students according to the nature of the course Object,and the activities of the place to establish the classroom and extracurricular two forms of practical activities and their corresponding specific types of activities.In the activity system,the design strategy of activity content,activity object and activity implementation is put forward based on the geographical core literacy,and the design model of astronomical practice is composed of subject and task,practice,output and evaluation.Finally,under the guidance of relevant theories,the eclipse and eclipse activities in the system of practical activities are selected,and the case design and demonstration are combined with the practice design strategy and model.
