I confidently walked into the class of grade five with a revised teaching case that had been revised N times.

The children were first excited at the math class in the computer classroom for the first time. A little after the adjustment, I open the box: “ the students love to listen to the story?
“ like! ” the sound is long, and I know they really like it.

“ Mr. Xie brought you a story and heard it together!
Suddenly, the classroom in perfect silence. The mouse is light, "the story of the seven bridge problem" begins.

At the end of the story, there is a question: can you go back to the seven bridge and go back to the starting point without repetition? I asked three students on the whiteboard presentations in turn, can see the painting, writing directly on the screen with a whiteboard pen, can change the color difference between the different methods, sit below the students no longer hold, the requirements to fall over each other.

After several attempts, it was found that none was successful. I wondered at the children said: “ one can not repeat through seven bridges, and return to the starting point, in fact is to see this picture can be a stroke, this is our mathematics often mentioned the issue of a stroke, the lesson we have to learn an interesting stroke.
The students are very interested in the content after they have tried.

When entering the new lesson, we will show six pictures through the whiteboard, let the students work together to draw a picture, determine which graphics can be drawn and what graphics cannot be painted, and initially perceive the rule of one stroke.


The fifth grade students' thinking ability stronger than I imagined much, they guessed that a picture can be a stroke may be related to the drawing point, line, shape and so on, the final number can be found under discussion with the singularity of the picture: a picture when the number of points is 0 or 2 of the time, the picture can be a stroke.

Learning mathematical knowledge is to solve the problems in life, I asked the students in a smooth way: do you need to draw and try a little like that at the beginning? Students will find, of course, do not need, directly according to the rule of law. Very soon, the students judged that only 2 and 4 of pictures could be drawn. One of the students with different opinions had corrected their ideas by drawing a picture and examining it on the whiteboard.

下面是研究畫法的絕佳時(shí)機(jī)了，學(xué)生們紛紛舉手示意要上來畫一畫，體驗(yàn)一番，沒被點(diǎn)來演板的學(xué)生無不嘆息，可見這白板的力量真是神奇，像磁鐵般吸引著孩子們的注意力。 The children looked attentively Yanban students carefully with whiteboard pen, a bright colored lines from their pen was born, the teacher gently reminded: pay attention to the students to observe the starting point and end point. At last, we find that figure 2 is an even number point, and finally returns to this point from any point. And Figure 4 has 2 odd points. It can start at a singular point and end with another odd point.

Such a chain, step by step, it has the student fish warehouse full of confidence,

To solve the related problems is already trying. Thanks to the ten pictures, the establishment of representation for the children to learn more thoroughly, thanks to information technology, rich material let the children panoramic view, bright colors make people memories, teachers and students in free writing on the blackboard and click the mouse to enjoy the pleasure of acquiring knowledge between.

In this lesson, students should develop the knowledge capacity, inquiry activities, the need for a large number of materials, and the operation of

It is not convenient to process demonstration research, it will be more difficult, so the electronic whiteboard teaching, improve the

The efficiency of teaching can achieve twice the result with half the effort.

Compared with the traditional mathematics teaching form, has the following advantages:




The traditional teaching form

The integration of teaching in the form of

1, three hours: a stroke of the law, a stroke of the painting, a comprehensive application of a stroke.

2, the teaching material is single.

3, students are given priority to listening, and knowledge is accepted passively.

4. The students' drawing is difficult to operate, and the process can not be presented.

1, complete in one lesson: an interesting stroke.

2, the teaching material is rich and varied.

3, students cooperate to explore, exchange and sum up the rules.

4, the electronic drawing board can easily choose pen type and color, can remove redrawn, replay the drawing process.

5, the whiteboard can combine the courseware with the board, save the space of the book, and the teaching effect is more obvious.

  the teaching content into a website,

More and more popular with teachers and students. The teacher can be

To make the teaching activities, the students also

Can the independent selective learning, and not to deviate from the course of

Questions, and the most popular &ldquo network engineering; pulse
There is a wonderful thing to do with the same thing.

For the purpose of &ldquo, &rdquo, and the needs of this content, the theme website of this lesson is built into a form of Sketchpad, which can achieve functions such as drawing, example learning, practice consolidation, clearance, playback and so on, so as to achieve good teaching effect.

There is a little like something like this: a Chinese is a dragon, three Chinese is a worm. No matter whether this sentence is unsuccessfulI think it's worth the Chinese people to remind ourselves how important it is to learn to cooperate with people. This course arranges student cooperation in perceiving one stroke rule, filling out statistical tables, finding strokes rule and so on. On the one hand, it improves students' ability to cooperate with others. On the other hand, it also shares teaching difficulties, saves classroom time and makes learning efficiency higher.

Information technology, for the new period of education into vitality, bring new feelings. The teacher is not too much to explain, and will show what can be can only be sensed; students can read books will live to experience the process of mathematical laws, and use, fully display the learning process and results.

Remember the moment that the class is about to end, a student yells: “ ah! This is so fast, I haven't played enough yet. ” yes, our children in mathematics and information technology integration is boundless, learning is happy in his eyes, they are willing to learn, active learning.


The development of information technology makes people's learning and communication break the time and space boundary of the past, and bring new space for the improvement and function of human ability. Information technology has long been regarded as a simple technology in learning. With the promotion of the new curriculum reform, the new curriculum advocates the creation of scenarios, and some teachers focus on making courseware. Some teachers use multimedia presentations, teach students to learn new words in this way, the writing process is not, strokes can not see it. The other teachers have made the courseware on the textbook, and then show them with multimedia. This is no doubt a lot of useless work.

The integration of information technology and discipline teaching means the combination of information technology, information resources and subject teachingAnd through the effective application of information technology in the teaching of various disciplines, promote the presentation of teaching content, students, teaching methods and teacher-student interaction in the transformation of the mode of learning, creating vivid information learning environment for students, the information technology has become the students' cognition, inquiry and problem-solving tools to cultivate the ability of information literacy and the use of information technology independent research and solve the problem of students, improve students' learning effect. [1]

The integration of information technology and curriculum can include three aspects: information technology as a teaching tool, learning tool, and environmental construction tool.



The integration of information technology and curriculum is the promotion and development of the original computer aided teaching concept. The original information technology teaching mainly focuses on auxiliary teaching, and the isolation of information technology from curriculum objectives cannot be regarded as an organic element of teaching structure, and results can not achieve good teaching results. In the course of integration will pay more attention to the rationality of teaching design, starting from the curriculum objectives, truly integrate information technology and teaching, information technology as the main tool to obtain curriculum learning content and learning resources, learning negotiation and discussion communication tools, knowledge construction and creation tools. The learner must choose the appropriate information based on the learning environment and goals and according to the expected results.



In the course of integration of information technology should constitute an effective learning environment, through information technology, can give students a real or virtual learning environment, learners in the real experience, learn in the environment and actively construct their own learning experience, learning environment construction, can effectively learn through the network communication function and function to create virtual learning environment.

The integration of information technology and curriculum implementation principles are as follows: [2]

1, guided by advanced educational thought and teaching theory.

2, closely around the “ the new teaching structure ” the creation of this core to carry out integration.

3, attention should be paid to the use of “ the teaching and design theory of &rdquo should be emphasized in teaching and learning, so that computers can be used as an auxiliary teaching tool and as a cognitive tool and an emotional incentive tool to promote students' autonomous learning.

4, attach great importance to the construction of teaching resources in various disciplines.

5, to combine the characteristics of various subjects to construct a new teaching model which is easy to realize the integration of subject courses.



Through effective integration can construct an ideal learning environment, this environment can support the real situation, unlimited resource sharing, fast and flexible access to information, a variety of interactive mode, breaking the regional boundaries collaboration, and is conducive to the cultivation of autonomous learning found creative and independent exploration, on the basis of this can be achieved which can fully reflect the students' subject role of the new study way.

The integration of information technology and the information technology curriculum, not only as an auxiliary tool for teaching or learning, but emphasized the need to promote students' autonomous learning of information technology as a cognitive tool and emotion incentive tool, using independent exploration, information technology provides multiple interactive and cooperative learning resources sharing, learning environment, initiative, the students to fully mobilize the enthusiasm, the creative thinking and practice ability of the students effectively exercise in the integration process, which is needed for the cultivation of innovative talents.
