Abstract: Teaching with a Interactive flat panel machine has become a popular color in today's classrooms. Through listening, watching, commenting, and comprehending, students fully perceive the original relatively abstract teaching content, adapting to the students' specific knowledge from abstract to abstract, thereby ensuring the smooth progress of teaching content. However, in the process of using, we found that there are some problems with the Interactive flat panel teaching: the Interactive flat panel teaching mode cannot replace the traditional teaching mode; there are too many courseware and the teaching amount is unreasonable; too much use of the Interactive flat panel teaching is not conducive to teachers' individual teaching The use of characteristics; display experiments with Interactive flat panel cannot completely replace the traditional demonstration experiments and other issues. How to avoid the above misunderstandings in teaching is a question before the teacher, and it is also a correct understanding of touch.
The key to the role of one machine in teaching
Teaching with Interactive flat panel has become a popular color in today's classrooms. Through listening, watching, commenting, and comprehending, students fully perceive the original relatively abstract teaching content, adapting to the students' specific knowledge from abstract to abstract, thereby ensuring the smooth progress of the teaching content. Although the use of the Interactive flat panel machine overcomes some of the disadvantages of the traditional teaching mode, during the use process, we have found that the Interactive flat panel teaching mode cannot completely replace the traditional teaching mode. It also has certain adaptability and limitations. For example, some teachers cannot correctly locate the role of Interactive flat panel teaching; some cannot properly handle the relationship between Interactive flat panel teaching and traditional teaching; some have various problems in the selection and design of courseware; The Interactive flat panel is unfamiliar and improperly used, which affects the teaching effect and so on. These all hinder the healthy development of touch-assisted teaching. Therefore, the following misunderstandings must be guarded when using touch-controlled teaching.
First, the Interactive flat panel teaching mode cannot replace the traditional teaching mode
The traditional teaching mode is an effective teaching mode concluded by the majority of educators through long-term practice and research. The current teaching mode still cannot be separated from the traditional teaching methods, and the Interactive flat panel teaching can only serve as a "assistance" and cannot completely replace the traditional teaching mode. It mainly displays content, pictures, video files, and individual demonstration experiments that are not easy for the teacher to play, and serves as the finishing touch and assistance.
Too many courseware and unreasonable teaching volume
Teaching courseware has a large amount of information and a fast pace, which can reduce the workload of teachers in drawing, writing, etc., thereby improving work efficiency. At the same time, due to the fast speed of information display using the Interactive flat panel machine, teachers tend to unconsciously accelerate the speed of classroom teaching. Ignore the beat of student thinking. Students have not had time to accept the previous message, and the next message is here again. The students are dizzying, can't hear, there is no room for pause and thinking, it is easy for students to have no time to take notes or simply not take notes. The review and consolidation of knowledge can easily lead to an increase in the amount of lectures. For example, in a high-quality class competition in our district, a physics teacher produced a series from the introduction of the topic, the identification of learning goals, the situational guidance, the tutorial process, and the on-site practice. The courseware includes pictures, text, and experimental videos. Can say
The writing is exquisite. During the class, no students were allowed to read books, no hands-on experiments, and no students exchanged discussions and taking notes. Instead, they were guided by the courseware one by one. At a loss, I don't know what I have learned in this lesson, and what are the difficulties? What knowledge is important? From the expressions that the students seemed to understand, they knew that they had failed in this class. The reason for the failure is that there are too many courseware. Although the teaching of Interactive flat panel is intuitive and helps students grasp the knowledge intuitively, it is not conducive to the cultivation of students' abstract thinking ability and spatial imagination ability and analysis ability. The teaching effect is sometimes counterproductive. Therefore, I think that the amount of courseware is sufficient, and it cannot replace other teaching methods.
3. Excessive use of Interactive flat panel teaching is not conducive to the characteristics of teachers' individual teaching. The widespread use of Interactive flat panel courseware has made teachers spend a lot of time and energy searching and downloading courseware, which tends to be the same as the subject and the same course content. Yu Leitong, coupled with the fact that many teachers cannot use the Interactive flat panel for teaching correctly, and turn the all-in-one classroom teaching into academic reports. The teacher "reads" the content of the courseware, which is not conducive to the "broad blooming" of classroom teaching, and it is not conducive to improving the teaching work of teachers. Level of innovation. I think: teachers should select the courseware that suits their own grid characteristics according to their own characteristics and edit again. Of course, in the editing process, we must consider the design of teaching methods and learning methods. This design process is that teachers carefully study the teaching materials and study the students' course preparation process. Only in such a classroom can the teacher's expertise be displayed and the teacher's demeanor displayed. For example, teachers of physics and chemistry students have strong hands-on skills, so they should guide students to do experiments and find problems and solve problems in the experiments. Chinese teachers have strong language skills, so they should use their beautiful, beautiful voices to attract students.
4. Display experiments with a Interactive flat panel machine cannot completely replace the traditional demonstration experiment. Physics is an experiment-based discipline. Physics experiment teaching is an important part of physics education, an important link to improve students' scientific literacy, and it is also a training of students An important way to observe, think, and practice. The new curriculum advocates that students' learning methods are "active participation, willingness to explore, diligence, and innovation." Physics experiments require students to form perceptual knowledge through sight, hearing, and smell in a real experimental environment. Only by providing real experiments that directly affect the senses, can they help students develop thinking and deepen their understanding of physical concepts that reflect material characteristics These are all irreplaceable touch teaching. In teaching, I found that some physics and chemistry teachers do not give students demonstration experiments, but use Interactive flat panel machines to demonstrate experiments. Some
The experiment process is relatively fast, and the students have not seen the phenomenon clearly, the experiment is over; some only show pictures, and there is no process. Individual teachers also use Interactive flat panel computers to display group experiments for students. They often use more classes, larger classes, fewer laboratories, and less equipment to excuse their responsibilities as excuses. I think these behaviors of the teacher are not desirable. He violated the requirements of the curriculum standards and the needs of the students' development. Our teachers should have the courage to shoulder their own responsibilities so that they are worthy of the title of "People's Teacher". In short, in order to teach, in the process of using the Interactive flat panel, teachers must pay attention to both science and perfection. Spend a lot of effort in class, the purpose is to increase the effectiveness of teaching and improve students' attention, instead of letting pictures, text, and demonstration experiments distract the subject from downplaying the subject content. To use the Interactive flat panel carefully and reasonably to optimize the classroom, teachers must work harder to explore and research.
