实验探究题主要考查学生的科学思想和实验探究能力,此类题目越来越受到重视。结合教学实际不难发现,实验探究结论的表述正确与否直接影响此类问题的得分率。调查、分析学生的答题情况,可将实验结论表述的常见错误类型总结为以下几方面。一、控制变量条件的缺失例1在“探究影响摩擦力大小因素”的实验中,记录的结果如表1所示 Experiments explore the main test of students’ scientific thinking and experimental exploration capabilities, such topics more and more attention. According to the teaching practice, it is not difficult to find out whether the expression of experimental findings directly affects the scoring rate of such problems. Investigation, analysis of the students’ answers, the common mistakes of the experimental conclusions can be summarized as the following aspects. First, the control variable missing cases Example 1 “Inquired into the impact of friction size factor ” experiment, the results recorded in Table 1
