Research On The Design And Application Of Family Physics Experiment In Junior Middle School

The physical home experiment is easy to use,easy to do,with obvious phenomena and strong interest.Experimenting with household items provides hands-on opportunities for each student.As a form of extracurricular activities,home experiment is a supplement and extension of classroom teaching,and plays an auxiliary role in junior high school physics teaching.The paper uses the literature research method to sort out the design and application of the family experiment.Questionnaire survey was used to understand the current situation of home experiment teaching in physics from four aspects: teachers' cognition,attitude,design and application of home experiment.Taking the "Shanghai Science Edition" eighth grade junior high school physics textbook as an example,the junior high school physics home experiment is designed by using household necessities and information technology means such as the Internet and smart phones,and presented in the form of "home experiment sheet",which is convenient for students to practice.Taking the optical theme as the carrier,the home experiment is used to create a real situation for teaching design,and teaching practice is carried out.Through quasi-experimental research,the teaching effect of applied physics home experiment is tested.Teaching practice shows that designing junior high school physics home experiments and presenting them in the form of "home experiment sheets" increases students' opportunities for hands-on practice and innovates the form of physics homework;the produced home experiment teaching videos are presented in the form of "QR codes" Presented,supplemented with physics teaching resources.The application of "Physics Home Experiment" to carry out teaching can improve students' interest in physics learning,and the comparative analysis of students' performance through pre-test and post-test can promote students' understanding of physics knowledge.Taking "physics home experiment" as the main line of teaching activities,aiming at cultivating students' core literacy of physics,we designed teaching cases on the subject of physical optics in junior high school,which enriched the form of physics teaching,provided teachers with a variety of teaching references,and provided teachers with a variety of teaching references.The cultivation of literacy provides a practical path.
