提高科学实验教学效率——有效实验数据的收集

Improving the Efficiency of Scientific Experiment Teaching——Collection of Valid Experimental Data

收集数据是学生科学实验中的一个重要环节,也是有效科学实验教学的前提。在小学科学实验教学中,我们要充分利用数据,用事实说话,提高科学实验教学的有效性。这就要求学生在数据收集中尽量的避免"另类"实验数据的产生,提高有效实验数据的收集。从实验前材料的选择、反复做预实验、制订实验方案等方面做充分准备为数据的收集打下基础。

Data collection is an important link for students in scientific experiments,but also the precondition of effective scientific experiment teaching. In the experimental primary school science teaching,we should make full use of data and facts,to improve the effectiveness of scientific experiment teaching. It requires students in the data collection as much as possible to avoid the "offbeat" the experimental data,improve the experimental data collected before the experiment. The choice of materials,pre experiment,fully ready to develop the experimental program to lay the foundation for the data collection.
