First, the optimal combination of information technology teaching and traditional teaching methods
Modern teaching media and traditional teaching tools are an inheritance and development relationship, not a relatively isolated or mutually exclusive relationship, nor a relationship in which one means replaces or denies the other. Modern teaching media is advanced because it enriches and develops traditional media. The traditional teaching method also has its unique advantages, because it is easy to prepare and conducive to students' personal experience. In the application process, the two should complement each other and go hand in hand, so as to create a better teaching atmosphere and achieve the goal of improving teaching quality in an all-round way. Therefore, when thinking about how to choose and use teaching media, we should try our best to consider the best combination of various media. Just like all the organs of the human body, although the division of labor is clear, they perform their duties, but only by optimizing the combination can their functions be fully exerted. Giving full play to the function of teaching media is also formed through the combination of various media. Only in this way can we choose and use teaching media better.
There is a song that sings very well, "Make new friends, but don't forget old friends". While affirming the convenience brought by multimedia teaching, we must not abandon some original good teaching methods, and we must not let some original media equipment, such as small blackboards, counters, triangular rulers, tape recorders, projectors, etc., be destroyed because of the establishment of multimedia mode 2 or mode 3. Teachers should use media flexibly in the teaching process to realize the organic unity of means and effects.
Information technology media can't replace blackboard writing. Writing on the blackboard is one of the basic skills of teachers. We should give full play to the role of blackboard writing and make the normal classroom move towards high efficiency. Some teachers blindly rely on multimedia in class, leaving almost no trace on the blackboard after a class, which is not conducive to students' summary of classroom learning content. In class, the teacher should write the key contents of this lesson on the blackboard, so that people can grasp the key points and difficulties after reading the blackboard. At the same time, we should also pay attention to the simplicity and beauty of blackboard writing.
Second, information technology teaching should be done when it should be done.
"Do it when you should" is a well-known lyric. In classroom teaching, of course, we can't abuse and improperly use information technology in teaching. However, the scientific and reasonable use of media teaching in the teaching of some topics can not only attract students' attention and stimulate their interest in learning, but also effectively break through the teaching difficulties, achieve teaching objectives and improve classroom teaching efficiency.
Psychologist Bruner said: "Learners should not be recipients of information, but participants in the process of knowledge acquisition." Let the students experience in the activities, produce the voice of the soul, and gain the motivation for growth.
Information technology teaching can vividly present the phenomenon of things, specifically express the development process of things, vividly reveal the changing law of things, transform abstract knowledge into a certain material form, become vivid, effectively highlight key points and break through difficulties.
Third, the use of information technology, focusing on effective teaching
In daily teaching, teachers should clearly realize that information technology is only an auxiliary means for teachers to carry out teaching activities. When using information technology and designing courseware, we should choose the appropriate media to organize teaching according to the age characteristics of students and the breakthrough of different knowledge. In classroom teaching, the media is a platform for teaching information and a tool and means to transmit information. Multimedia-aided courseware is not only used to convey the teaching content, but also to change the traditional teaching methods and learning methods, from point to surface, from abstract to image, from static to dynamic, so that students' feelings and vision form a distinct impression of time and space and stimulate their interest in learning.
In primary school teaching, a large number of illustrations with various forms and rich contents are an important part of teaching materials, but the illustrations are static. With the help of multimedia and illustration, dynamic situations are created, and the activity process is fully displayed with bright colors and moving pictures, which can not only highlight the key points, break through the difficulties, turn the abstract into concrete, but also promote the thinking orientation from fuzzy to clear. Einstein pointed out: "Imagination is more important than knowledge, because knowledge is limited, and imagination sums up everything in the world. Strictly speaking, imagination is a real factor in scientific research. "
For example, in the teaching of "calculation with calculator", at first, the teacher used the audio-visual media to show attractive associations, and guessed one item according to the prompt. The first prompt was related to numbers, and the second prompt was a calculation tool. Tip 3 was born in ancient times, and Tip 4 has seven abacus beads on each file. Students can quickly say that it is an abacus. Then the teacher changed Sansi to one born in the last century, which is very light and can be shaken to make students associate with it, thus introducing new lessons. Einstein pointed out: "Imagination is more important than knowledge, because knowledge is limited, and imagination sums up everything in the world. Strictly speaking, imagination is a real factor in scientific research. " Imagination is a psychological process of processing existing images in the human brain to create new images. It has the characteristics of visualization, generality, integrity, freedom and flexibility. Therefore, any creative activity is inseparable from imagination, which is an important symbol to measure a person's creative ability.
Fourth, be flexible and make information technology work for me.
At present, in information technology teaching, what teachers lack is flexibility and flexibility for us. Among the teachers who use multimedia courseware, there are often people who are afraid of operating mistakes. For convenience, the courseware is designed as sequence structure. When you press a key in class, the courseware will be "played" in sequence. In this way, the class is a "mobile class". Without teaching wit, teachers try their best to lead students' ideas to the established process of multimedia. Multimedia-led teaching process seems to be a common problem. For example, in the teaching process of "Understanding Triangle", different triangles are displayed with computer courseware, and the characteristics of various triangles are displayed with different colors. Bright pictures and pleasant sounds give students strong and diverse stimulation, which enables them to correctly understand the names of various parts of triangles and form clear representations of different triangles in their minds. On this basis, students have initially discovered the characteristics of various triangles through cooperative inquiry, and then use recess to help students and verify the findings. At the same time, when students try to operate, it also plays a very important role in stimulating their interest in learning.
In a word, multimedia-assisted teaching is a new exploration in the practice of educational reform, which can not only arouse students' learning enthusiasm, but also develop their intellectual factors such as mathematical knowledge, ability and thinking.
