What are the common methods of project analysis and evaluation?

Project analysis methods: loss expectation method, simulation method, expert decision method, risk classification matrix and probability influence matrix.

The discrimination obtained by internal consistency analysis does not necessarily represent the validity of the test questions; A problem with low discrimination index does not necessarily mean that this problem has shortcomings; The validity of item analysis data in classroom tests changes with time, not fixed; Research shows that it takes almost five times as long to prepare new projects as to modify existing ones.

That is, from the ideological content of the topic, the appropriateness of content sampling and the clarity of expression. It is to analyze the questions (items) that make up the test according to the test results, so as to evaluate the quality of the questions and screen the questions.

Extended data:

1. In education, if the purpose of the examination is to understand the knowledge and skills of the subjects in a certain aspect, there is no need to consider the difficulty too much.

2. Most tests hope to measure the differences between individuals more accurately. When choosing a topic, it is best to make the average difficulty of each question close to 0.50, and the difficulty of each question is between 0.50 and 0.20.

3. The average difficulty of general ability test and achievement test is about 0.50.

4. Screening tests (selective and competitive tests) should adopt items with difficulty close to the admission rate.
