First, courseware application, grasp the connotation, so that learning is solid and effective.
The integration of information technology and mathematics curriculum is the need of the development of the times. Teaching content, means, methods and students' learning methods also develop with the development of the times. In the information technology environment, the effectiveness of classroom teaching depends on whether teachers grasp the role of information technology in the teaching process and find the best opportunity to apply information technology. When designing courseware, we should focus on the breakthrough of teaching emphasis and difficulty, as long as we really express the problems that teachers find difficult to explain clearly with the unique advantages of multimedia.
For example, in the teaching of the course "Characteristics of Triangle" taught this semester, at the beginning, we showed how to abstract triangles with pictures about triangles in our lives, and then use triangles to solve problems in our lives. In the teaching of triangle stability, it is difficult for students to judge whether the triangle surrounded by three fixed-length straight lines is the same or not because of the different positions of wooden sticks. At this time, the courseware is used to demonstrate the process of the stick around the triangle. Through rotation and superposition, students can see that "as long as the length is determined, the shape of the triangle is unique", and the conclusion is naturally drawn, so that students can "feel" and "discover" in operation.
For another example, in the teaching of parallelogram area, three different cutting and spelling methods are demonstrated through the media. In the demonstration of the coordination of the action, height flicker and sound of scissors, and in the comparison with "arbitrary cutting", the focus of "cutting along the height" is strongly highlighted, and students have a clearer and deeper understanding of "translation" and "transformation". In addition, in the "formula derivation" link, audio-visual combination and dynamic-static combination are realized. In the flashing, moving and overlapping of arrows and different line segments, the conclusions of "equal area", "equal length of parallelogram and rectangle" and "equal height of parallelogram and width of rectangle" are clearly reproduced. It not only reproduces the students' operating process and thinking process, but also permeates the new ideas and methods of "understanding in operation", "discovering in operation" and "internalizing in operation".
With the help of media, we can intuitively reproduce the formation process of knowledge, turn boring written expressions into vivid teaching materials, prompt and adjust students' thinking, fully mobilize students' learning enthusiasm, break the original learning methods and models, break through important and difficult points, maximize students' intelligence and potential, cultivate students' spatial imagination, and get twice the result with half the effort.
The second is electronic whiteboard, which highlights interaction and makes classroom teaching even more powerful.
The progress of society provides new technical means for teaching and new learning methods for students. The introduction of electronic whiteboard into the classroom has undoubtedly injected more blood of information technology into the teaching methods of our school, making the role of information technology more powerful.
1. Improve teachers' teaching efficiency and make teaching fruitful.
Using electronic whiteboard teaching, we can directly operate the computer on the electronic whiteboard, including the courseware opened on the computer. In the teaching process, we can annotate, sketch, edit and drag on the electronic whiteboard at any time, so that the teaching focus can be presented to students more intuitively. You can easily use the functions such as curtain drawing, photography and searchlight in the menu to enhance students' interest and improve their attention; You can write freely on the whiteboard, show and edit pictures and videos, and make the monotonous blackboard writing colorful and vivid; Using video display, some exercises written on paper or reference materials and students' problem-solving methods can be directly projected on the whiteboard, which makes students' communication and defense more intuitive and makes teaching more convenient, practical and effective.
2. Improve the classroom teaching atmosphere and enhance the interaction between teachers and students.
Using electronic whiteboard teaching, teachers can let different students take turns to operate on the stage according to the teaching content. Teachers can also guide and explain students' mistakes in the process of answering questions, which can better stimulate students' interest in learning, enhance the classroom atmosphere and enhance the interaction between teachers and students.
For example, when solving problems, students can draw pictures on the whiteboard and explain the conditions and problems of a given topic. Students with different ideas can also modify the labels on the whiteboard in time with pens of different colors, so that the thinking process and interactive communication process of a topic can be clearly displayed on the screen. In particular, some geometric shapes, such as counting how many pieces are made, observing the shapes of all sides, and similar problems that are difficult to interact in courseware, can realize students' independent operation and explanation by using electronic whiteboard technology, and simplify complex problems intuitively. The electronic whiteboard provides students with more opportunities to show themselves.
3. The flexible use of interactive technology makes the classroom full of vitality.
In the past few years, I have deeply felt its powerful charm, and I am willing to share its achievements with you. Last year, I was honored to participate in the city whiteboard application skill competition, and wanted to show my understanding and application of whiteboard. The topic I chose is "equivalent replacement". It can be seen from the title that its essence is "substitution", so it is a wide-angle mathematics course with strong operability, interactivity and rationality. I have seen many examples of using courseware to show the substitution process before. However, due to the limitation of our teacher's courseware production level, some good ideas can't really be moved and replaced in the courseware. Therefore, I bring forth the old and bring forth the new, carry out teaching by means of "electronic whiteboard", take the interaction between teachers and students as the fundamental purpose and promote the transformation of students' learning methods as the basic point, showing the powerful advantages and unique charm of information technology.
In the application of media, this lesson highlights the visual image with pictures, shows the process with whiteboard interaction and video booth. In this lesson, whiteboard infinite cloning technology is used the most. In the fruit exchange and seesaw game, three kinds of fruits, scales and small animals to be exchanged are set as infinite clones, which are placed at the bottom of the screen, and students can drag them freely to replace them by using their reciprocal relationship; The process of equivalent substitution is clearly reproduced, so that students can vividly perceive equivalent substitution and break through the difficulties of students' learning. In addition, the ordinary pen function of whiteboard software is used to annotate and write, the spotlight effect is used to find the focus of attention in the picture, and the process of students' substitution is displayed on the video display platform, all of which make the interactive application that can not be realized in multimedia courseware at ordinary times possible, which greatly stimulates students' interest. In the interaction between teachers and students, students' thinking really moves, making the classroom more vibrant and energetic.
With the skillful application of whiteboard, the lesson "Equivalent Replacement" won the first prize in the primary school group of the 20 13 Yangquan Primary and Secondary School Teachers' Electronic Whiteboard Application Skills Competition. This is just the beginning, and the technology of whiteboard is far more than that. I believe that through our unremitting research, the interactive function of whiteboard will definitely make classroom teaching more vivid.
Third, blog application, build a platform, and improve in communication.
Only communication can improve. In this information age, it has become a way of life to look up information online and collect and accumulate various learning resources. Students can learn about mathematics in life through the internet before class and exchange ideas in class. Teachers use blogs to record the problems found in teaching in time, reflect on various phenomena in teaching, accumulate gains and experiences in teaching, and more importantly, learn from other people's advanced experiences, enjoy all kinds of excellent sources and exchange views. Blog has opened up a broader space for cooperative teaching and research.
This semester, in the blogosphere forum, we participated in the "information cup" classroom teaching observation and discussion, from which we learned the highlights of each class and gained a lot of valuable experience. Different comments in the same class also teach us what kind of perspective and height to evaluate a class. In addition, this semester I also participated in the interactive communication with experts on the Internet, and saw the experts' detailed explanation of "how to cooperate effectively in groups" in teaching, and had a deeper understanding of this issue in examples; There are also online lectures and comments organized by the teaching and research section, which let us feel the changes in theoretical cognition and teaching methods brought about by information technology.
