بررسي يكي از عوامل ضعف دانش آموزان در مبحث ديناميك

One of the weaknesses of students in dynamic topics

از آنجا كه مبحث حركت در دبيرستان از جمله مباحث چالش برانگيز است ما بر آن شديم تا به بررسي علل اين ضعف بپردازيم. به همين منظور با ارزيابي برگه‌هاي امتحاني ترم اول درس فيزيك پايه دوم دو دبيرستان در شهرستان ورامين پي برديم كه يكي از مشكلات دانش‌آموزان چگونگي استفاده از قانون دوم نيوتون است. براي ريشه يابي مشكل پرسشنامه اي طراحي كرديم. نتايج حاصل از تحليل پاسخنامه ها اطلاعاتي را در اختيار ما قرار داد كه به نظر مي رسد براي تدريس اين مبحث مفيد است.

he dynamic topic in high school physics books is a challenging topic we decided to investigate the cause of this weakness. For this reason we checked physical exam sheets in second-high school for the first semester in two high schools in Varamin city. We found that one of the problems is how to use Newton’s second low. We designed a questionnaire for this problem. We give the useful results from the analysis of the answer sheets. These results can be helpful for the teaching dynamic topics.
