项目摘要

Inquiring Abilities of Students' into Experimental Results in Elementary PhysicsThis study makes research on how students pursue better experimental method to reach physical standard values and keep measured values from scattering as much as possible.The research focuses on following experimental tasks ;1. Standard experiments in elementary physics :(1) Frequency measurement of a tuning fork(2) Forcal length measurement of a thin lens2. Experiments specislly designed to develop the inquiring ability of students' :(1) Electric resistances of cooking aluminum foils(2) Constraction of a voltmeter and measurement of electric resistances3. Experiments using daily life materials to measure :(1) Sound speed in air using castanets(2) Refractive index using marking pins(3) Brightness of a miniature light bulb using solar batteryIt can be concluded as follow ;many students do not give enough consideration to measured values and tend to hand in impressionistic reports after the type 3 assigments as well as the type 1 regardless of their difficalties. However the type 2 in which explanations are given between each step of experiments lead them to write successful reports.

学生对基础物理实验结果的探究能力本研究旨在研究学生如何追求更好的实验方法，达到物理标准值，并尽可能避免测量值的分散。本研究主要完成以下实验任务： 1．基础物理标准实验：（1）音叉的频率测量（2）薄透镜的焦距测量2．专门为培养学生探究能力而设计的实验：（1）蒸煮铝箔的电阻（2）电压表的制作及电阻的测量3．使用日常生活材料测量的实验：（1）使用响板测量空气中的声速（2）使用标记针测量折射率（3）使用太阳能电池的微型灯泡的亮度可以得出以下结论；许多学生对测量值没有给予足够的考虑，并且在类型3作业和类型1作业之后无论其难度如何，都倾向于提交印象派的报告。然而，类型 2 在实验的每个步骤之间给出解释使他们能够写出成功的报告。
