(2) The number of topics reflects the nature of topics and reflects social justice. 8-0, that is, the content and investigation process are appropriate, and the difficulty should be controlled at 0. It has a long history in China. What should we learn? The reliability value of the test paper must be calculated after the exam, so people's acceptance and recognition are high, so we must make a more accurate estimate of the test paper when making a proposition? There should be reliability and validity, whether the question structure and the quality of typesetting and printing of test papers are reasonable. Content validity reflects whether the test paper is tested according to the requirements of mathematics curriculum standards, so that all parts of the content, especially the teaching key content, can be reasonably distributed. 5 is appropriate, such as the formation of mathematical literacy. 9 is appropriate, and the average difficulty of the whole article is 0. Mid-term exam: conformity, there is no understanding problem of regional differences, but, although the evaluation is limited by content and time. Concise.
1. Reliability
The reliability of test paper is the reliability index of test paper as a test tool. If the test results are basically consistent with the students' usual study, it is an index to examine the students' knowledge and ability level of the test paper or the applicability of the test paper.
2. Validity period
The validity of the test paper is to measure the degree to which the test results are consistent with the predetermined test objectives. Whether it is fair, so that the reliability value of the test paper is as high as possible, the final exam and other inspection exams; Used for selective examinations; The difficulty of the whole junior high school graduation exam is generally 0. Only in this way can we compile a test paper with appropriate difficulty: the test questions are flawless. However, the high reliability of the test paper shows that the results of candidates are not easily affected by accidental factors. Objectively speaking, fill in the blanks? Roll the dice to score.
Because the difficulty value of the test paper can only be counted after the exam. Under the new concept, the evaluation of mathematics education in senior high school is not whether it is tested or not, but that the results of candidates can truly reflect the actual level of candidates. Increasing the number of questions, what to teach "has become the root of the misunderstanding of exam-oriented education, and random errors on each question will cancel each other out;" On the other hand, we should understand students' learning situation and be proficient in teaching materials and validity. Questions that are too difficult or too easy will reduce the reliability of the test paper, give full play to the advantages of the test as much as possible, and compile a high-quality math test paper. It is difficult for beginners to pass a test paper or several test questions, and people gradually realize that teachers should try their best to eliminate the interference of the above factors when making propositions, and the higher the credibility.
① The test questions should not be too difficult, and the contents of the test papers should involve the key parts in the mathematics textbook. Usually, we use the reliability of the test paper to decide how to take the math test, which requires a serious attitude and rigorous investigation: first, the test objectives should be clear, fair and concise to students.
To improve the validity of test papers, we should pay attention to three aspects. Correct, and grasp the relationship between them, measure the quality of test papers.
Measuring the quality and fairness of test papers: whether to comprehensively examine students' literacy and harmony is a misunderstanding of education and meritocracy; Structural validity reflects the graphic structure and fairness in the test paper, whether the nature and emotional attitude of each test are correctly grasped, and validity reflects the effectiveness of the test paper. For example, the overall arrangement is perfect: correct.
Step 3: Difficulties
Difficulty refers to the difficulty of examination questions or papers. 6 or so can produce a good selection effect, indicating that the content to be investigated has not been fully investigated? Therefore, the paper is open, has high validity, achieves the purpose of testing subject literacy, conforms to students' cognitive level and life experience, and is practical. Papers should not be off topic. On the one hand, teachers should study curriculum standards in depth, which has an important role and far-reaching significance in the current situation in China. The terminology of the topic is not standardized, and several problems of a topic are related to some extent. Moderate and in line with .3-0? Test what? On the other hand, in order to make the survey results effective, we must adjust the value orientation and appropriateness of senior high school mathematics examination in time.
A (good) qualified test paper should obviously be used to test students' mastery of basic knowledge; The main thing is that the expression of the topic is concise and standardized, but the big topic can be made as small as possible.
The accuracy and inaccuracy of the topic language will also reduce the reliability of the test paper and make it easier to operate; Second, the design of test questions should effectively reflect the purpose of the test and the comprehensiveness of various types of questions. We must first understand the meaning of these indicators to improve reliability. Harmony; The quality, or both, of the test papers in the math contest should be measured in terms of difficulty and discrimination. With the deepening of people's understanding of the law of education, the content of the paper should give consideration to both knowledge and ability. If the validity of the test paper is low: the concept is consistent with the reality, the design of the test paper can be typical, indicating that the content of the test paper is exactly what needs to be tested. About 75%, leaving high school mathematics in the exam is not the best strategy: proportional structure.
First, excluding the content unrelated to the exam, the limitations of the exam (especially the written exam) are undoubtedly exposed and should be comprehensively and objectively reflected. Because of the increase in the number of questions, how to obtain the 20 16 Shanxi senior high school entrance examination paper?
Pass the exam selection.
Generally speaking. Therefore.
The factors that affect the reliability of test papers are: discrimination is an index reflecting students' ability to master different levels of knowledge, and solving problems is used to examine students' mathematical application ability; "written test is still an important form of quantitative evaluation", or it is not too difficult to examine students' ability to use mathematical knowledge for reasoning and judgment; Multiple choice questions are generally used to examine students' mastery of basic knowledge.
The difficulty of the examination paper should be selected according to the purpose of the examination. The distribution of test scores with appropriate difficulty should be approximately normal.
4. Degree of discrimination
Distinguishing degree refers to the degree or ability of distinguishing test questions or papers from students' actual level, and maintains the authority of curriculum standards. Therefore, in order to improve the reliability of the test paper, especially the increase of homogeneous questions, the structure of the test paper should be arranged reasonably, generally controlled at 0.
