初三一模数学备课组成绩分析VIP免费

2015-2016学年度初三一模数学备课组成绩分析2016年5月16日一、成绩分析：从整体来看，3班和6班成绩较为突出，首先可能有班主任效应问题，其次是学生体会了学习数学的乐趣，会学且乐学。1、7、8成绩不是很理想，可能最主要原因还是被动学习的学生较多，转走了一部分优秀学生后，有的班级在课堂教学中缺少领军人物，听的多，思维的少，比较懒惰。再有就是有些特殊学生参加考试，也会直接影响成绩，年级成绩也很不理想。但平均分全区第9，及格率第7，优秀率第8，还是完成了学校保8争7的任务。二、试卷分析：本次考试共考察39个知识点及6个能力点，学生的分析问题解决问题能力，逻辑思维能力，数据的分析观念及空间观念都不强，所以就体现在能力题上各班的得分率都很低。本次考察我们发现知识点得分率年级低于70%的达到了20个，一半之多，特别是解直角三角形，平行四边形、矩形及菱形的性质判定，一元二次方程根的判别，三角形及特殊三角形的性质判定这些非常基础的题都出现了问题，实属不应该，教师必须认真反思自己的教学整理一模试卷，出专项复习题，题组训练，尽快提升这部分的成绩，争取达到不丢分少丢分。知识点编号知识点内容年级得分率班级得分率1班2班3班4班5班6班7班8班[39]根据新定义确定待定系数的取值范围9.23%8.05%7.14%14.44%12.35%6.86%15.15%5.56%4.30%[40]根据新定义12.40%18.97%19.64%13.33%14.81%10.29%13.64%3.33%6.45%班级平均分最高分最低分优秀率及格率班级名次任课老师1班79.341131520.69%65.52%6金芳2班81.89104157.14%89.29%4金芳3班86.031074613.33%80.00%2于晓庆4班80.96105157.41%77.78%5于晓庆5班83.381091211.76%88.24%3张建秋6班86.641122115.15%84.85%1张建秋7班75.33106143.33%70.00%8郑书华8班76.68107213.23%74.19%7郑书华年级81.371131210.33%78.93%/确定待定系数的取值[35]利用函数图象求待定系数的取值范围15.84%22.99%14.29%24.44%17.28%13.73%16.16%8.89%9.68%[27]解直角三角形21.98%20.00%25.71%22.00%22.22%18.82%27.88%23.33%16.13%[32]图形的判定25.41%24.14%30.36%35.00%31.48%19.12%24.24%21.67%19.35%[37]矩形的性质、全等三角形的判定26.65%36.21%25.00%31.67%28.70%21.32%26.52%22.50%22.58%[16]一元二次方程求根公式的依据30.30%33.33%30.95%30.00%30.86%22.55%38.38%33.33%23.66%[25]函数解析式的确定36.98%31.90%29.46%50.00%27.78%42.65%49.24%33.33%28.23%[38]新定义概念的理解40.36%34.48%36.90%50.00%50.62%34.31%53.54%28.89%34.41%[30]图形的定义50.83%51.72%64.29%43.33%29.63%44.12%66.67%43.33%61.29%[10]探索实际问题中的函数关系59.92%72.41%67.86%56.67%55.56%70.59%69.70%46.67%38.71%[29]选用统计图表表示数据63.02%56.03%63.39%54.17%56.48%73.53%78.03%59.17%59.68%[22]平行四边形的性质和菱形的判定63.09%59.77%71.43%68.89%64.20%61.76%73.74%64.44%40.86%[14]一次函数的应用65.01%56.32%67.86%67.78%66.67%71.57%70.71%54.44%63.44%[23]三角形、平行线的性质66.12%62.07%67.86%71.67%70.37%67.65%74.24%68.33%46.77%[34]图象交点坐标的确定67.22%58.62%64.29%77.78%53.09%71.57%78.79%70.00%60.22%[28]式的应用67.36%68.97%57.14%56.67%62.96%85.29%66.67%66.67%70.97%[26]切线的性质、直角三角形的性质67.98%67.24%76.79%75.00%79.63%73.53%69.70%61.67%41.94%[15]数据的收集与整理68.46%64.37%69.05%68.89%62.96%69.61%70.71%68.89%72.04%[13]一元二次方程根的判别68.73%42.53%57.14%84.44%72.84%71.57%81.82%61.11%75.27%式[33]抛物线解析式的确定71.07%65.52%71.43%76.67%66.67%73.53%81.82%70.00%61.29%[36]依据文字语言画图71.49%65.52%75.00%76.67%74.07%76.47%75.76%60.00%67.74%[9]尺规作图73.97%75.86%78.57%80.00%81.48%88.24%69.70%60.00%58.06%[31]图形的性质75.83%70.69%80.36%78.33%83.33%67.65%83.33%75.00%69.35%[21]分式方程的应用78.35%72.41%74.29%86.00%77.78%78.82%87.88%68.67%79.35%[12]多边形的内角和78.79%80.46%82.14%78.89%72.84%84.31%71.72%84.44%75.27%[7]众数和中位数的确...
