氧化還原反應(yīng)化學讀本編寫初探
[Abstract]:Chemistry textbooks include chemistry textbooks, teaching aids and so on. The current middle school chemistry textbooks are poor in readability, simple in content, unable to obtain clear knowledge in reading textbooks, lack of popularization of science, lack of interest, lack of scientific thinking and scientific methods. Teaching materials only focus on problem-solving, too much exercise training seems boring. By studying and studying the excellent textbooks of science courses abroad, this paper studies and compiles the chemistry reading books suitable for the middle school students in our country, so that the students can effectively construct the chemistry knowledge and understand the scientific methods through self-reading. Improve learning interest and learning efficiency. The research on the subject has creative suggestions on the reform of chemistry teaching in middle schools, which will also lead to a meaningful discussion on the compilation of chemistry textbooks in middle schools. On the basis of literature and theoretical research, this paper refers to the teaching materials of "Science", which is an excellent science publishing house in the world, and takes students' autonomous reading as its guiding ideology. The principle and the concrete writing method of the chemical reading book are established, and the rich and picturesque and rich reading book is prepared with the example of "redox reaction". The reading books are studied in the ninth grade and the first year of senior high school students. By checking the completion of the students' exercises, we can understand the students' self-study results, and give the reading books to some senior high school chemistry teachers to read for advice. The results of reading practice show that: 1 the students can master the basic knowledge independently. After reading, the third grade students can finish the exercises basically. The correct rate of the students completing the exercises is similar to that of the high school students who only teach by teachers, and the accuracy rate of some exercises is even higher than that of the high school students. Therefore, students can master knowledge independently through reading books. 2 readers have readability. The knowledge statement is detailed, clear, the language is easy to understand, the text organization has the strong logic. To the redox reaction knowledge introduction comprehensive, complete, the thought is rigorous. Therefore, the teachers who read this book approve. 3 the writing of the text is interesting. Language is basically lively and enlightening. There are many interesting experiments and life tips in the readbook. The things selected in the book are as close as possible to the life of the students. They are useful and can be used for learning. Therefore, it can attract students' interest in reading. 4 the reading book is scientific and popular. The reading book embodies the idea of STSE and pays attention to improving the students' scientific literacy and consciousness. It is helpful to cultivate the students' ability of inquiry and good at thinking and to appreciate the emotion of science.
