"Learning problems must be carried out in real situations" is a constructivist view of learning. Constructivism theory holds that learning is always associated with a certain social and cultural background, that is, "situation". Learning in real situations can stimulate students' associative thinking, make them use the relevant experience in the original cognitive structure to assimilate and index the new knowledge they have learned at present, thus establishing a connection between old and new knowledge and giving new knowledge a certain meaning. In other words, let students learn in real situations and reduce the gap between knowledge and problem solving. Therefore, the design of constructivist teaching system emphasizes the design of learning situation, provides students with a complete and true problem background, restores its original vividness and richness, thus promoting learners' autonomous learning and cooperative learning, and achieves the purpose of actively constructing knowledge meaning.
These are all theoretical words. Let's look at some living examples.
For example, on the 27th, the content of Xu Xiaoping's lecture was the "location determination" of eighth grade mathematics. In the introduction of the courseware, the position of two warships is determined by searching for the position of friends in the parade and in the maritime determinant, which creates a situation, which can not only reflect the reality of mathematics, but also fully attract students' attention, so that they can feel the necessity of determining the position in real life and think about the method of determining the position. This situation introduces nature, fully stimulates students' national pride and points out the importance of positioning in life.
The situation here is an educational situation, which has a direct impact on the educational effect and is an atmosphere and environment with certain educational significance composed of specific elements. Creating a good teaching environment can awaken students' subjective consciousness and produce a strong desire to explore. Usually, there are three types of classroom situations: problem situations, story situations and realistic situations. The creation of every situation requires our front-line teachers to make serious decisions.
Wonderful teaching is in the classroom. When we can properly integrate information technology into subject teaching, stimulate students' learning motivation, make students willing to learn and become active learners, then we have completed half the task of the new curriculum standard.
Second, the use of multimedia technology to expand teaching capacity, increase classroom density
This advantage of modern information technology can best be reflected in the review class and practice class, so I won't say much about the benefits during this period. I want to emphasize the power of information technology in expanding the teaching ability of new courses. Our daily classroom is just a point of teaching, and the purpose of teaching is to guide students to master more relevant knowledge through this point-drawing a face. Due to such teaching requirements, our classroom teaching can not be limited to one point and one line. With the help of Internet, a huge information network, information technology provides great convenience for the expansion of contemporary education and teaching, and enriches and enriches our classroom content.
A, the comprehensiveness of background knowledge. Chinese is a comprehensive subject, so it is necessary to know the author's life and background knowledge before class to interpret a work. If teachers make the author's life and related background knowledge into PPT in advance, they can demonstrate or intercept the corresponding video clips in class, or walk into the online classroom, which will not only leave a deep impression on students, but also help to break through the difficulties.
B, the integrity of art appreciation. The comprehensive application of information technology in teaching greatly improves classroom efficiency and saves a lot of unnecessary time. For example, in art teaching, such as silhouette painting and paper printing. Hand-made products occupy a considerable proportion, and classroom demonstrations will take up a lot of time. If you shoot some excellent paper prints and the whole production process before class, you will first guide students to appreciate the excellent paper prints in class, and then tell them that these works are not painted, but printed by production methods. How are they made? Please watch the video below. The students' attention was focused on the screen at once, and the teacher gave a little hint beside them. After reading it, ask the students to recall the production steps just now. If there are any omissions, you can go back and watch it again, which can strengthen students' memory and help them master the main points of production. In this way, the whole teaching process is more compact, students can master art skills skillfully and the teaching effect is more ideal.
C, the infinity of time and space. In physical education teaching, most students know little about basic basketball tactics such as passing, cutting and joint defense, and they are slow and nervous when they cooperate with teachers in tactical demonstration. As a result, they spend a lot of time and fail to achieve the expected teaching effect. We can organize students to watch NBA videos and intercept some wonderful clips for tactical coordination analysis. Intuitive and uncomplicated teaching scenes are very consistent with the psychological characteristics of modern junior high school students. The series of sports teaching films "Basic Basketball Techniques" broadcast by CCTV is also a good TV teaching program. It can be directly applied to the classroom of sports audio-visual education. Basic basketball skills
Thirdly, using multimedia technology to break through teaching difficulties and improve classroom teaching efficiency.
In order to realize the cognitive goal in classroom teaching, it is necessary to solve the standard problems of "highlighting the key points" and "breaking through the difficulties". In traditional teaching, there are many ways to solve these two problems, such as language narration, wall chart display, hands-on operation, blackboard writing analysis, and combination of lecture and practice. Today, our teaching has information technology as a teaching aid, which lights up the regular classroom teaching and naturally helps to highlight key points and break through difficulties.
(1) Stimulate interest and make a breakthrough in the growth of new knowledge.
Our teacher will be very attentive to the initial appearance of each knowledge point in classroom teaching, hoping to guide children with a good start. In teaching, if we can choose the teaching media that best reflects the transformation from abstract to intuitive and from difficult to easy, we can show students the teaching situation and break through the important and difficult points, so as to achieve the expected teaching purpose. Just like "topography and contour lines" mentioned by Xia Zhan during the expert group training in summer school, the relationship between contour line shape and terrain height and slope is a difficult point for junior one students. With the direct participation of information technology, students can master the basic ability of reading pictures with sound, animation and graphics, and cultivate students' thinking in images, thus breaking through the key and difficult points of teaching. Topography and contour lines
(2) Turn static into dynamic, and make a breakthrough in the ambiguity of observation.
Herbart once said that "real sensory observation is preferable to simple description". In teaching, to solve the contradiction between abstraction and visualization of knowledge, we can make full use of the feature that information technology can turn a still picture into a moving picture to express the formation of knowledge.
This is the courseware "Biological Intruder" that I just finished in the safe and high-quality classroom teaching competition. As a rational exposition, the author wants to warn the world to protect the environment by expounding the great harm brought by the invasion of alien species to human society. However, most of our students do not have the conditions to search for information online, and it is difficult for the surrounding environment to provide them with similar scientific and technological information. I don't know what a biological intruder is, and there is no clear concept of biological invasion. This invisibly increases the difficulty for students to understand the text, and further affects their appreciation of the vivid, humorous and humorous language features of the article. Clever use of pictures can make all kinds of alien invasive species appear one by one, display "invasion" intuitively, reduce the strangeness of text understanding, and successfully realize the teaching goal.
(3) Crossing time and space and breaking through thinking barriers.
As one of the four ancient civilizations in the world, China has left a lot of words, pictures and material objects in its long history. In recent years, movies and documentaries with historical themes have appeared constantly, such as Romance of the Three Kingdoms, Long March and founding ceremony. A large number of graphic materials make the cooperation between history department and information technology unique. Teachers can make use of the advantages of network resources, combine teaching practice to screen, sort out and refine, fundamentally change the old routine of looking at history and copying feelings, and realize the digitalization of lesson preparation. Let history be vividly and intuitively displayed.
Fourthly, how to use information technology to carry out reform and innovation and explore new teaching modes.
Here I would like to report to you the groping process and some experiences of our Chinese teaching and research group in building a new composition teaching model for many years.
Teachers engaged in Chinese teaching must have the feeling that writing is difficult: difficult to teach, difficult to change and difficult to improve. Just say that this year's senior high school entrance examination Chinese composition: "I read." To tell the truth, according to the tips after the composition, it is not difficult to review the writing questions. However, when we are marking papers, we can still see such compositions everywhere: I filled in the "title" after reading it, and his composition was "I read the title"; After reading it, I fill in "Chinese" or math, and his composition is entitled "I read Chinese"; After reading it, I fill in the "back" or the title of any article in the Chinese textbook is the same. His composition is "I Read the Back". How can such an absurd reality not worry us?
Years of teaching experience make us understand that writing is difficult because students don't have enough food to cook, and because students don't know how to feel and refine life and how to turn different life experiences into personalized language. In 2006, all Chinese teachers in our school realized the important role and superiority of modern educational technology in improving composition teaching by learning modern educational theories and renewing their concepts. Therefore, we decided to put junior high school composition teaching under the modern information technology environment and study it as a subject, aiming at finding a new way to improve students' writing from their lives. Use educational information technology to create situations, introduce students into them, feel the texture and richness of life, find emotional harmony and harmony, and then produce creative aspirations and divergent thinking. So we use the school to build a campus network and build a school composition website-Wenfeidi; To establish a campus literary society, all experimental classes should build class magazines, register class blogs, combine excellent works with modern information technology to the greatest extent, and organize students to actively participate in various forms of composition competitions.
◎ This is an award-winning student work "Who Stole My Leisure Time" created under the guidance of Mr. Huang Shanping of our school, and won the first prize in the 8th National Computer Making Competition for Primary and Secondary Schools in 2007. The biggest motivation for students to be passionate about composition creation is to be recognized by the public. In 2007, the news of the 8th National Computer Making Competition for Primary and Secondary Schools came, and the teachers of our research group and the computer specialty group of our school felt that this was a good opportunity for our project to move forward. So we told this news to every student in the experimental class, and asked them to make a comprehensive investigation on the psychological attitude of contemporary middle school students first, and then establish the theme for creation. When the theme composition "Who Stole My Leisure Time" was decided, all the students enthusiastically devoted themselves to the creation of the theme composition. Then, our teacher, Mr. Huang Shanping, trained our finalists in computer production. Under his careful carving, Zou Longjie, a student from Class 2 1 Grade 2, finally stood out with the electronic manuscript of girlhood, and finally won the first prize of the Eighth National Computer Making Competition for Middle School Students. The exciting news spread all over Jishui County at once. Such a big prize, a 13-year-old child and a computer, these topics have become the key words that parents and students praise. Good results inspired all the members of our research group, and the people of the county gave us respect and praise, which made us feel that the days close to modern information technology and scientific research curriculum reform were not wasted. Taking advantage of the enthusiasm of the whole school, we put forward the slogan of participating again in 2008. Therefore, teachers and students in the school have unprecedented enthusiasm for the integration of modern information technology and disciplines.
◎ This is the class blog I registered on Sina last year-FarmNo. 1865. Later, we will invite small bloggers to show and explain their farms for you personally, so I won't go into details here. Make full use of modern information technology, build a technical platform for your composition teaching, encourage students to give full play to their resource advantages under the network environment, realize the meaning construction of composition through cooperation and exchange, and exchange the form of composition teaching reform for teaching progress.
◎ In May, 2065438+00, I participated in the 5th China Middle School Students' Composition Competition and the 1st Jiangxi Middle School Students' Composition Competition organized by junior middle school students' friends. Class 2 (18) Xu won the first prize in the province, 2 students won the second prize and 3 students won the third prize.
After three years, with the attention of leaders and the wisdom of all Chinese teachers, we successfully completed this topic and created a brand-new composition teaching model for junior middle school students in our school. This model maximizes the development of composition resources, opens up the time and space of composition, and finally achieves the goal of cultivating and improving students' writing ability. )
