The rapid development of electronic technology has brought endless convenience to all walks of life, with more convenience of electricity, and more convenient electronic facilities make people free of their hands and improve work efficiency.
In school, of course, there are all kinds of high-tech electronic products, electronic blackboard is one of the most popular teaching aids for teachers, it is mainly composed of a computer motherboard and a large screen monitor, the display is a touch screen, you can control the computer without a mouse or pen, it is very convenient.
On the side of the monitor are two blackboards that can be used to write with a dry-erase pen to make it easier for the teacher to write on the board. The electronic blackboard has so hard that the traditional blackboard has been eliminated, so that many young teachers have never even seen chalk!
There are two sides to everything, the machine is good is convenient, and the bad is excited! Sometimes electronic products will be naughty, it also needs power, if there is no electricity, it will stop working.
Teachers are most afraid that there will be no electricity in class, and they are usually fine in class, but if there is a power outage in an open class or teaching and research class, it will be very bad. Veteran teachers generally have strong adaptability, and it doesn't matter if they don't have an electronic blackboard, they can still complete the task. But young teachers are different, they don't have PPT courseware is equivalent to no hands, and they can't complete the task at all!
This young teacher Lin from our school made a fool of himself in front of the leaders of the Education Bureau and the teaching and research staff who were listening to the lecture yesterday.
Although Mr. Lin has only been working for three years, his final exam results in each term are in the forefront of the city, and he has been valued by the leaders of the bureau, so he has been assigned a task to let him and two other excellent teachers each have an open class.
Mr. Lin was full of confidence, and prepared this class more than a month in advance, and under the care of the school leaders and the head of the teaching and research team, he prepared the lesson many times, drilled, and revised the deficiencies until everyone was satisfied!
Yesterday morning, during the first class, for some unknown reason, the school suddenly had a power outage. The maintenance master said that it might take a morning to check before he knew what the problem was.
There was no way, all the teachers and leaders who listened to the class were present, and these three teachers could only attend the class step by step. The first two teachers are older, work longer, and have more experience, although there is no PPT class, the effect is not good, but it is passable.
In the third class, it was to Mr. Lin. He was in a math class, and at first he used the method introduced by review, printing the problems on paper and sending them to the students to practice.
To the second step, the teaching example, this is the example problem of finding the circumference of the circle, Mr. Lin's preparation is all on the PPt, there is animation design, there are also teaching difficulties, there is no electricity can not be turned on. He also has little experience, so he can only explain according to the example problems in the textbook, and when he mentions the students, many students do not understand the circumference of the circle.
When I went to the classroom to practice, I asked 3 students to play the answers, and only 1 was correct, and Mr. Lin looked at the more than a dozen teachers and leaders listening to the class at the back of the classroom, with an embarrassed and helpless expression!
Originally, this open class, which had been prepared for more than a month, had a good effect, but because there was no electricity and the software could not be used in the class, the efficiency was greatly reduced.
During the class evaluation, the leader also criticized Mr. Lin for making the public class so bad, and questioned whether he did not prepare for the class?
Mr. Lin felt very aggrieved, thinking that I was ready for everything, and there was no phone call temporarily, so blame me?
It seems that all the classes rely on PPt software, sometimes it is really unreliable, and it still requires a combination of technology and manual work to meet the standards!
