So what teaching effects can't be achieved without using information technology? According to the observation of classroom teaching with and without information technology, we will find the following incomparable effects brought by information technology to the classroom by traditional teaching, which improve the teaching efficiency.
Teachers often need to demonstrate to the whole class in teaching, including art, handicrafts, calligraphy, scientific experiments and so on. After watching the demonstration, students will practice by themselves according to the steps or skills demonstrated by the teacher. In the traditional class, because the teacher usually demonstrates subtle movements, such as the method of holding the pen and the order of strokes, the method of carrying the pen, the position of injecting water in the experiment, etc. Only every student can see these subtle movements clearly, and only a few people can stand next to the teacher and watch them carefully, but this way the teacher has to demonstrate many times, which is quite a waste of time.
Video booth is the best tool to solve this problem. As long as the lens is aimed at the demonstration operation area, you can see the projected image on the electronic whiteboard or touch the all-in-one machine, so students don't have to come to the teacher in droves to watch the demonstration. Teachers can even capture images in real time, or make videos of the demonstration process, so that students can practice while watching the replayed videos. What is a good textbook in class? In this paper, Liu Jiaxiang, a teacher from Shanghang No.1 Middle School, used the video booth to continuously shoot the current intensity indicator on the ammeter and record the experimental data. Lei Shengfeng, a teacher from Hang Cheng, demonstrated the painting method of blue-and-white decorative painting under the video booth, which was introduced in the article "Listening to Jay Chou and Painting Blue-and-White Porcelain", which made the teaching display have better on-the-spot and exhibition effect.
In addition to the video booth, teachers can also use their smartphones to take photos, video or broadcast live. Different tools can make demonstration teaching more efficient.
When information technology is integrated into the teaching classroom, students must use at least one technology terminal to participate in classroom activities. Through the student terminal, teachers can collect students' feedback in real time, including pressed keys, input text, drawn pictures or edited documents. All students' feedback can be processed in real time by teaching software, and the data can be drawn into statistical charts, files or images for comparative analysis, or the received information can be classified to reflect the most real learning situation, and experienced teachers can make the most effective teaching arrangements according to these feedback information.
For example, according to the keystroke data collected by IRS instant feedback device, teachers can display students' personal options, group statistics or class statistics according to teaching needs, and can also compare two different answers to the same question.
From the most superficial application point of view, the statistical chart displayed after teachers' questions and students' IRS feedback can let teachers know the students' mastery of the previous teaching content in real time, so as to adjust the content and progress in real time. Furthermore, through the comparison and discussion of the data answered two or more times, students can be stimulated to have a deep dialogue on the same question and concept, and their thinking direction and content can be effectively trained.
