Local resource-enabled classroom : management exploration of low-cost practical education in county junior middle schools——A Study on the Practical Path of Physics Study Tours in Junior High Schools Based on the Regional Characteristics of Mishan City

With the promulgation of the " Compulsory Education Physics Curriculum Standards ( 2022 Edition ) " and the deepening of core literacy orientation, practical education has become the key path of basic education reform. As an important bridge between subject knowledge and the real world, the value of research travel is increasingly prominent. However, for the vast number of county junior high schools with relatively scarce resources, prominent security pressures, and heavy teaching tasks, how to transform research from ' luxurious extracurricular activities ' to ' normalized teaching links ' is a core problem that plagues front-line education managers ( especially principals ). This study takes Mishan City, Heilongjiang Province as the sample field. Under the guidance of STEAM education concept and Dewey 's " learning by doing " theory, it faces the four realistic tortures of " where do the funds come from, " " how to manage the safety, " " how to evaluate the effect " and " how to integrate with teaching " when carrying out physics research practice in county schools. By systematically sorting out and developing the local resources of Mishan represented by Xingkai Lake, Honey Mountain, Cold Ice and Snow, Youth Reservoir and Beidahuang Culture, this study innovatively constructs and practices a set of lightweight school-based research management mode with ' low cost, near field and deep integration ' as the core concept. The model specifically resolves the contradiction between teacher coordination and teaching progress through the ' task-driven and teaching-research integration ' mechanism, strictly controls safety management risks through the ' near-field and process solidification ' strategy, and responds to teaching achievement assessment demands through the ' process quantification and effectiveness explicitation ' tool. After a one-year practical verification, this model not only significantly improved students ' interest in physics and knowledge application ability ( such as an average increase of more than 50 percentage points in the understanding rate of core concepts ), but also gave birth to a complete set of school-based curriculum resource packages, and formed a transferable and replicable ' Mishan experience '. This paper expounds in detail the generation logic, operation path, implementation effect and reflection enlightenment of this model, aiming at promoting county schools based on local resources.
