1. Comparison and analysis of the use of all-in-one touch machines
Investigate, analyze and compare from the following aspects. First, after the school has undergone system training in early September 2016, all 27 classes in the school have been required to use the touch all-in-one machine normally within the use time, and the total utilization rate has reached about 40 percent . The second is to carry out statistical analysis by subject: mathematics usage rate is 27.5 percent , English usage rate is 70 percent , language usage rate is 41 percent , geographical usage rate is 81 percent , biology usage rate is 83 percent , physics usage rate is 50 percent , and chemistry usage rate is 20 percent . The third is the analysis of the school stage: the utilization rate of all-in-one computers in junior high schools is about 60 percent , and that in elementary schools is about 30 percent . Analysis of the age range of teachers: the utilization rate of all-in-one computers for teachers under 45 is about 75 percent , and the utilization rate of all-in-one computers for teachers over 45 is about 10 percent . Fifth, the statistical analysis of the primary and secondary school students' knowledge mastery: the knowledge point comprehension and mastery degree are relatively higher than that of traditional teaching.
From the above data, it can be seen that: (1) Geography, biology, history, and ideological character have a relatively high utilization rate because pictures and video materials such as geography, biology, history can be displayed intuitively, which is convenient for students to read and analyze pictures. The medium usage rate of Chinese is because the beautiful essays, poems, etc. with music and pictures in Chinese teaching can make students immersive, so Chinese teachers prefer to use them. The low usage rate of chemistry is due to the fact that students have specialized experimental classes, and intuitive experiments are easier for students to master than courseware. The low usage rate of mathematics is because some teachers believe that the writing process on the blackboard is a process of understanding students' logical thinking in mathematics, and they prefer traditional teaching. (2) The utilization rate of elementary school is lower than that of junior high school because elementary school basically only has Chinese, mathematics and English, and other subjects are rarely used. (3) Teachers in the age group over 45 years old basically do not use computers, and about 75 percent of teachers under 45 years old will use computers after passing the training. (4) The improvement of students' knowledge is due to the large classroom capacity after using the all-in-one machine. Some knowledge points are more intuitive and easier for students to accept.
Second, the advantages and problems of the touch all-in-one machine
After 4 months of practice, the school has explored the outstanding advantages of touch all-in-one in the use of education and teaching. One is that the touch all-in-one machine integrates the traditional blackboard, projector, and computer, and becomes an important method of classroom teaching, which greatly improves the efficiency of classroom teaching. The second is to use an electromagnetic pen instead of a mouse to operate at will on the all-in-one machine, which not only facilitates the operation of teachers, but also enhances the communication between teachers and students. The third is that the class capacity is large, the resources are abundant, and the writing time on the blackboard is saved. The classroom is rich and colorful, convenient, intuitive and visual, and easy for students to understand, which truly realizes the interaction between teaching and learning. Fourth, the touch all-in-one technology integrates text, sound, pictures, and images, which not only helps stimulate students' interest in learning, but also makes learning easier and more convenient for students. Fifth, the knowledge review is strong in summary. Most teachers like to use an all-in-one machine when reviewing, because the physical projection in the all-in-one machine can directly project the review content they summarized by themselves, which is convenient for students to review. Sixth, most students and teachers like and accept this new modern education and teaching method. Students like the teaching of the touch all-in-one machine very much. This teaching method not only improves their understanding ability, but also stimulates their interest in learning. Teachers use computers to comprehensively process graphics, numbers, animations, sounds, backgrounds, etc., which also makes it easier for students to understand and master the teaching content. Seventh, the tenth division has established a teacher domain cloud platform. Through the use of the education cloud platform all-in-one machine, it is more conducive to the use of high-quality resources in education and teaching.
At the same time, the touch all-in-one machine also has some problems in use. One is that some teachers did not use the hardware correctly, which caused the all-in-one machine to overheat, and the all-in-one machine was often in an inoperable state; the clicking speed of the hand and pen was too fast, which caused the system to stagnate and affect the class. Second, the use of all-in-ones is monotonous, and there is a lack of excavation and utilization of the functions of all-in-ones. The third is that the timing of the use of all-in-ones is sometimes inappropriate, and there is a lack of proper grasp of the time and amount. Fourth, the transformation of teaching methods is only a formality, and the functions of the all-in-one machine are insufficient. Fifth, because it is just beginning to use, some teachers still regard it as the same as the previous simple multimedia teaching. It does not give full play to the role of touch all-in-one, and the production of courseware is insufficient. The courseware cannot fully reflect the characteristics of teaching. Further excavation in practice. Sixth, some students just stay in the fun of pictures, texts and images, and they are not focused enough, and the teachers are not paying enough attention to the students.
Through various trainings, the school has improved the level of teachers' use of information technology and has achieved remarkable results. For example, Mr. You Huaming's "Application of One Yuan One Inequality" choice program video lesson won the first prize of the Bingtuan Young Teachers' Math Video Lesson. Mr. You Huaming cleverly created situations based on the reality of life and made full use of multimedia to introduce the reality of life into the courseware. "We are members of the Corps" and "183 Tuan Ehe Liquor Industry has been built into a national 3A-level tourist attraction", these contents are visually displayed in front of students with multimedia, which arouses students' strong interest in learning
