Normality Test Method In Examination Paper Evaluation

The exam is not regarded as a measure of student learning and mastering the mathematical degree of good means, at the same time it also is to examine the teacher’s classroom teaching effect is a very effective method. Teachers can also according to the students’ examination (including papers in various parts of the score analysis)to decide the emphasis of mathematics teaching, students can know from which they have not mastered the difficult, so exam to truly promote and advance teaching and learning effect. But above all these all must establish in the examination of rational basis, of course, only the proposition reasonable test can more accurately reflect the teaching and learning situation, which in mathematics examination proposition in the key link of the need for a scientific method to carry on the effective assessment. A good test is considered in addition to the knowledge coverage, also need to grasp the difficulty of examination questions, which can make more students to learn mathematics with confidence.This paper argues that, under normal circumstances, a reasonable proposition papers, student test scores should obey the normal distribution, according to the frequency and frequency distribution curve, can intuitively reflect the general examination of the situation, and get the frequency distribution curve was high in the middle of two low, around roughly bell-shaped normal state, reflecting the comparative examination of normal.Questions to degree is moderate, the frequency distribution curve of normal distribution curve of approximate Yu Zheng. If the distribution of peak curve to the left, is a reflection of low more, a lower average, examination questions difficult. If the peak curve to the right, reflects the high more, average higher, examination questions of partial simple.And as the paper candidates score distribution in horizontal acceptance testing hypotheses, illustrates its obey normal distribution, coefficient of skewness and kurtosis coefficients which are smaller, the examination paper proposition basic rational.The paper divided into70.2points, also described in this paper proposition is difficult to properly.Therefore, each time after the end of the examination, we can adopt the normality test method from the test question difficulty, carries on the appraisal, so as to lay the foundation for further analysis of examination paper.
