第二篇:七年级数学综合能力测试小结

镇安慧源学校七年级数学综合能力测试小结

为了全面培养学生的数学分析问题、解决问题能力、提高数学综合素质,结合能力考试测试要求进行了全面全员测试,现小结如下:考查目的:为了全面培养学生的数学分析问题、解决问题能力、提高数学综合素质,锻炼学习方法,特别是合作学习,探究学习,分析讨论。

考查范围:七年级数学(上)

考查对象:七年级全体学生

考查方式:制作成试题,提前安排好任务,学生周末先进行调查,获取数据,然后统一时间分析完成试题,考查时分小组进行。

分值:20分。

评分:由学科组三位老师按照教研室下发的数学能力考查赋分标准流水作业打分。

考查效果:

(1)达到A等的占 20 %,B等的 占25 %,C等占45% ,D等的占10%。

(2)优点:学生重视程度高,数据收集准确,符合要求,能从实际出发。条形统计图和扇形统计图绘制准确,发挥性题目能发挥小组的优势,合作探索,积极讨论,语言组织得体。

(3)不足:存在细节上的问题。如部分学生在绘制扇形统计图时,各部分百分数相加不等于1,或没标清楚各部分占总数的百分数。在绘制条形统计图时,少了单位或未在图上写清楚具体数额,第二题中

在证明时过程不够精炼,回答

5、6问题时语言较模糊,不规范等。

建议:1.加强数学语言表达能力和分析问题能力训练,充分利用数学课加强指导和培训,通过探究学习,合作学习,利用形式多样的数学活动吸引学生,激发学生的学习兴趣。

2.针对突出问题的学生,要分门别类的对症下药,长期训练。特别是探究学习,合作学习能力和发散思维的提高,多激励和表扬,增强其信心。
