This year, I was lucky enough to participate in the research on the topic of "Practical research on the evaluation of theme-based science and technology courses", but my understanding of this topic is not deep enough. With my own doubts, I read the book Evaluation of Preschool Education published by Beijing Normal University, from which I learned a lot. The following are some of my gains to share with you.

First of all, this book systematically studies the basic theory of preschool education evaluation. The concept, historical evolution, main types and basic theories of preschool education evaluation are analyzed in detail. For example, the evaluation of activities includes two aspects, one is to evaluate the value of an activity itself, and the other is to evaluate the value of the means adopted in the activity to achieve the goal. Preschool education evaluation is a process of judging the social value of preschool education, which takes preschool education as the object and gives value judgment to its effectiveness. Preschool education evaluation has its unique characteristics. Preschool education evaluation is a constantly changing concept, which is constantly enriched, perfected and enriched. It is also a systematic process of collecting data, and the evaluation of preschool education depends not only on the data obtained from one observation and test. Before evaluating the collected information, it needs to be fully explained and analyzed. Preschool education evaluation is a feedback-correction system. Through continuous judgment, analysis and comparison, it can be judged whether the process is effective in every step of preschool education. If it is effective, what measures must be taken to ensure the effectiveness of the process, so as to provide scientific and timely services for preschool education decision-making and better preschool education policies. For beginners who have just come into contact with educational evaluation, they must first master these basic concepts before they can have a deeper understanding.

Secondly, the basic principles of preschool education evaluation point out the direction for us to formulate evaluations in various fields. The basic principles of preschool education evaluation include: directionality, feasibility, comparability, comprehensiveness, purpose, objectivity and subjective initiative. For example, the feasibility principle says: "The evaluation index system should be simple and easy to measure, consistent and universal, and should not be overly demanding of accurate evaluation results. The evaluation method must be simple. For example, the purpose principle says: "The evaluation of preschool education must have a clear purpose. Any evaluation should have a specific purpose, not for the sake of evaluation, and put an end to the phenomenon of random evaluation, that is, evaluate what you like and what you like. These evaluation principles mentioned in this paper are very helpful for us to formulate evaluation tables in the field of disciplines in the future. Although we know these principles now, we still need to digest them carefully and make a scientific evaluation form in combination with the actual situation.

This book is about the general aspects of preschool education evaluation, and the evaluation of science and technology education I studied is a very small branch. In the future work, we should refine the evaluation of pre-university education to the evaluation of small science and technology education. There are also some good educational evaluation schemes in the book, which I will continue to read in my spare time.
