Since the beginning of last semester, our province has begun to use new textbooks, which put forward new requirements for teaching concepts and teaching methods. In order to adapt to the new textbooks and enable students to learn more deeply and intuitively, mathematics teacher Wu Tiande of the No. 4 Middle School of Tianshui City has made mathematics multimedia courseware popular among students through nearly a year of research, and won the national and provincial and municipal awards.
This is Wu Tiande, a senior and third grade mathematics teacher in the city ’s fourth middle school. Since using the new textbook, Wu Tiande has had the idea of ​​making multimedia courseware.
Wu Tiande, a mathematics teacher at Tianshui No. 4 Middle School: I feel that if you want to take a good new course, you must first use multimedia. The role of multimedia is to visualize abstract content. This is a major feature, and secondly, it makes us boring math. The content is interesting. Because of these two ideas, I thought that I must study and use multimedia courseware to serve students in the classroom.
With this idea in mind, Mr. Wu started making various multimedia courseware about teaching as soon as he had time, but he had almost no experience with computers before.
Wu Tiande, a mathematics teacher at Tianshui No. 4 Middle School: Especially the SeienceWord software is a new software. There are many differences between him and our usual teaching software. One of my learning of these software is to communicate with me by software experts through online dialogue. Pointing.
After the guidance of experts and peers, Wu Tiande delved into how to make multimedia courseware. Although he has been engaged in mathematics teaching for many years, it is not easy to make a good courseware. He delved into the two courseware of arbitrary-angle trigonometric functions and ellipses and their standard equations, which were completely designed according to the concepts and requirements of the new textbook, and it was revised repeatedly before and after, which took nearly a year.
Wu Tiande, a mathematics teacher in the fourth middle school of Tianshui City: mainly highlights one idea, two changes and three developments. One idea is to take student development as the idea, three developments are the development of teacher resources and student resources, and the development of material resources. Two changes are the change of teacher teaching methods and the change of student learning methods. Secondly, my design mainly highlights the use of SeienceWord software, and uses the effects of intuitive, vivid, and animation to create an intuitive, vivid, and good learning atmosphere for students.
The original teaching method was that the teacher told the students to listen. After Wu Tiande's multimedia courseware was made and demonstrated in the classroom, the students could more easily understand the contents of the books, which not only increased the students' interest in learning, but also enhanced the learning initiative.
Tianshui City No. 4 Middle School Student: I think that the way Wu uses multimedia is more direct, more convenient to observe and more vivid than blackboard writing. I prefer Teacher Wu to teach us this multimedia method.
Tianshui City No. 4 Middle School students: Train our spatial imagination ability. The spatial thinking we learned this semester. If this is the case, the object can be imagined. .
After being affirmed by students and colleagues, Wu Tiande was more confident. He decided to get the two courseware of arbitrary angle trigonometric functions and ellipses and their standard equations made by himself to the "14th National Multimedia Education Software Competition" The results of the evaluations were unanimously praised by the judges. In the end, the trigonometric function of any angle won the national second prize, the ellipse and its standard equation won the national third prize.
