Study On The Research Of Junior Physical Items Based On Real Life Experiences

In recent years, under the guidance of the new curriculum reform, the physicsexam of junior high school also launched a courageous reform, the content of theevaluation close to actual and contact to the student’s life experience. Since the newcurriculum, it can be found from junior exam that the examination reforms haveachieved a very good result, such as the junior physical items which contact to reallife experience gradually appeared in all kinds of examinations, especially in thejunior exams. Which focus on testing the students’ ability to apply knowledge toanalyze and solve practical problem. So that designing junior physical items based onreal life experiences is an inevitable trend. Down homeopathy, we should urgentlystudy and resolve the question that how to design the exam questions well base onreal life.This thesis through literature research to summarize and sort out the research ofjunior physical items which contact real life and the relevant research of it’s design.And then analyses the meaning of Life Junior Physics Items and discuss thecharacteristics, level, type and value of Life Junior Physics Items through specificexamples deep and theoretically. Life Junior Physics Items in addition to have thebasic features of the general questions, but also have situational, science-oriented,objective truth, integration, application and catalytic characteristics. According to theitems designing and purpose of the evaluation focused on different questions,it can bedivided into four types,such as intellectual Life Junior Physics Items, backgroundLife Junior Physics Items, purpose Life Junior Physics Items, problem-solvingprocess Life Junior Physics Items. And three levels in the followings single, double,integrated of according to the degree of life. It can help students to develop the abilityof creative thinking, problem solving, or practical applications and to improve thelevel of scientific literacy of students, and also to help enrich evaluation theory.Based on system analysis to the Life Junior Physics Items, the thesis focused onit’s specific design. And protocol designing principle of scientific and authentic,situation blending of knowledge and the life material matching students’ lifeexperience level, fairness, and situation novelty. From it’s three elements "assessmentcontent,""problem situation","design mode" and according to it’s four different types,study out the corresponding design approach and refine five basic design steps.Through the study it can be found that select the appropriate life material is the key to designing Life Junior Physics Items, and design questions based on the contentof evaluation and the selected context is the core proposition. This is also the maindifficulties faced by designing Life Junior Physics Items, because it is not easy toselect the life material which appropriate specific physical knowledge, and alsoconsistent with the student’s experience and knowledge level. There also exist thequestions that seemingly practice, but do not meet the actual in the junior physicsexam. At the end of the thesis, for the difficult and problems faced by the proposition,put forward some suggestions on how to make Life Junior Physics Items. Expected togive teachers and propositions some provides that have certain significance toimprove the quality of the questions in junior physics exam that under the newcurriculum oriented, so that promote and development the exam reform.
