Case 1- 1 Teacher Ma skillfully uses DVD (case source: modern distance education project in rural primary and secondary schools)

Teacher Ma is an ordinary primary school Chinese teacher in a small town in the west. Today, Ms. Ma is going to give a lesson about "clear lake" to her first-grade children. Picking up the textbook, Mr. Ma can't help but recall the scene of this class before: students who have never seen the lake, it is difficult to understand the lakes and mountains described in the text, and they can only mechanically recite more than a dozen new words in the text, which makes the class look very long and boring.

It is difficult to understand the syntactic difficulties of "... such as ..."

But today is different. Before class, Mr. Ma carefully watched the lesson "Clear Lake" taught by a famous primary school special teacher in the east thousands of miles away on DVD. Mr. Ma feels that he has learned a lot from it. "Students will love this course today!" Teacher Ma has a well-thought-out plan. It's time for class. Teacher Ma stood confidently in front of the podium and said loudly, "It's spring, and we all want to go out for a spring outing!" " ! Let's watch a scenic film together! "Ma said, and pressed the" play "button on the remote control of the DVD player.

Beautiful pictures of beautiful scenery, lakes and mountains appeared on the TV screen: blue sky, white clouds, clear lake water, reflected green hills and small fish swimming in the lake water. At this time, there is a family of three, and parents are leading their children to ripple in the lake in a small boat. The whole family was intoxicated by the beautiful scenery. Not far away, a child who was also sitting on the boat just wanted to throw the leftover bread paper into the lake, but when she saw the clear lake, she couldn't bear to break the beautiful lake, so she kept bringing the waste paper back to the shore and putting it where it should be.

Teacher Ma pressed the "pause" button and asked, "Students, what did you see just now? Which classmate can tell me? " The students scrambled to raise their little hands: "beautiful lake" and "beautiful mountain" ... everyone told what they saw. Teacher Ma asked, "Do you want to hear what the children on TV say?" When the students answered eagerly, Teacher Ma pressed the play button again. The children on TV also scrambled to say, "I see the quiet lake against the blue sky and white clouds." "I see the green hills on both sides of the river and their charming reflections in the lake." ...... "Do you want to say it again, what did you see just now?" Teacher ma inspired. So the inspired children gave many wonderful descriptions. "A silver fish swims around the green lake, as if performing for everyone." "The peaks on both sides of the river are like eagles with wings spread, and some are like lovely rabbits" ... "Do you want to hear what the teacher on TV said about the children there?" Teacher Ma started the screening again. ...

After a brief comment on DVD, the special-grade teacher began to read the text aloud. This used to be the biggest headache for Teacher Ma. Accustomed to speaking local dialects, she always has difficulty in pronouncing some words, so she is embarrassed when reading the text aloud. Now listen to the teacher's standard beautiful pronunciation on TV. Teacher Ma asks the students to read after it. After reading the text, Mr. Ma stopped at the new words and said to the students. "These are what we want to know today. Some of them you may know. Can you tell me how you know them? " The students gave their own answers. "Do you want to know how children on TV remember these words?" Teacher Ma began to play again. ...

Like two classes separated by a window. On TV and outside TV, children who are far away from Qianshan study and practice together, as if they were really in class together. The teacher in the TV set reads standard, writes standard and teaches brilliantly; The teacher outside the TV is broadcasting correctly, stopping skillfully and teaching really. Teacher Ma not only takes the scenery films in DVD as resources, but also makes up for her own shortcomings with the standardized teaching in DVD. She also specifically asked students to pay attention to the learning methods of students in DVD. In this class, Mr. Ma also asked the children in the DVD to compete with the children in his class. They are better at pronunciation, word recognition and sentence making, just like two big groups in the same class.

Before you know it, class should be over. Teacher Ma saw the clear and happy light in the students' eyes. Teacher Ma smiled happily.

Case review

Before class, Ms. Ma used DVD as a tutor when preparing lessons. She attaches great importance to learning all kinds of teaching and learning skills used by special-grade teachers in DVD, imitating all kinds of learning activities organized by teachers in CD, and making simple and effective teaching AIDS and learning tools used by teachers in CD by herself. In class, Teacher Ma regards DVD as an auxiliary teaching tool. Teacher Ma sometimes uses video resources to create situations for students, sometimes uses video clips of classroom teaching to support students' learning, and sometimes even uses student activities in videos to make students in DVD become "virtual learning partners" of middle school students in her classroom for competitive learning. After class, Teacher Ma uses DVD as an auxiliary tool for reflection and study. Teacher Ma often watches classroom videos on DVD after class, and then reviews her classroom teaching. After comparison, he wrote down many lessons after class. Gradually, Mr. Ma began to apply more and more teaching models, methods and skills used by special-grade teachers to his own classroom. While imitating and thinking, she has more and more good teaching design schemes. The role of DVD has gradually changed from the center of knowledge dissemination to the learning resource center and teaching support center of Teacher Ma.

Traditionally, DVD can only be used for one-way communication, but it has become a teaching resource center, a learning support center, a situational creation tool, a "virtual learning partner" for students and a reflection tool for teachers. What's the point? Obviously, it is the guidance of correct educational technology ideas and methods.
