The promotion and application of modern educational technology is another commanding height in school development. In recent years, Wuzhifeng has firmly grasped the development opportunity of modern educational technology, and has clearly put forward the solution of "dust-free class". Under the attention of the Education Bureau and local governments, Wuzhifeng has Great steps have been taken in use, and there are now more than 50 marketing companies nationwide.

Especially in 2011, taking advantage of the 12th Five-Year Plan, Wuzhifeng equipped a number of schools across the country with high-standard multimedia equipment, and each class was equipped with environmentally friendly multimedia equipment for a dust-free teaching environment. Classrooms can teach, demonstrate courseware, and play video programs in a dust-free and healthy environment, truly achieving "dust-free class communication." The improvement of the teaching environment and the renewal of teaching methods have impacted the teachers' traditional ideas, changed the teaching methods of the teachers, and injected new vitality into the school education and teaching reform.

1. "Clean Classes" has changed the traditional concept of teacher-student relationship

Although the traditional idea of ​​teacher-student relationship is that teachers should respect, love, and understand the concepts and requirements of students, it also emphasizes that teachers have absolute dominance in educational and social relationships. Students can only obey, not evaluate teachers at will. Under the influence of this traditional concept, some teachers have a strong sense of superiority in psychology, often fail to put down the shelf, are unwilling to communicate with students as equals, and cannot take the initiative to communicate with students. Because in the eyes of students, teachers always know much better than Wuzhifeng. The development of human society has made knowledge grow geometrically, especially the development of network technology, which has multiplied the speed and spread of information. If teachers do not keep pace with the times and do not absorb fresh nutrients, they may become With the new illiteracy, teachers are no longer the authoritative persons with knowledge. "It is not necessary for students to be inferior to teachers, and teachers are not necessarily good at life" will become a reality. Under this background, teachers are encouraged to calm down and re-examine their role status. On the one hand, they force themselves to catch up and continue to charge. On the other hand, they communicate with students as cooperators and mentors on an equal basis, so that Students really participate in the process of exploring knowledge, especially when they encounter difficult problems in teaching activities, teachers and students use network tools to find solutions, and more consider the cultivation of students' learning ability, practical ability and innovative ability.

2. The "Clustless Classes and Classes" enrich the school's moral education

Each low-light quantum environmental protection teaching board in Wuzhifeng classroom is equivalent to integrating the three functions of green board, projection screen and electronic whiteboard. In order to maximize its role, Wuzhifeng tries to find the potential functions of these devices to serve Moral education in schools.

First, enrich students' cultural life. Using the noon break, they can play cartoon English teaching VCDs suitable for the age of students. On the one hand, it enriches the monotonous learning life of students. The English conversation has cultivated students 'oral English ability, and also cultivated students' interest in English. It can also broadcast music programs or animation programs that children like to hear, enriching students' campus cultural life.

Second, integrate education with fun. Regardless of whether a parent meeting is held, leaders and retired teachers are invited to give lectures. In order to enhance persuasion, the students are surveyed in advance and the data are collated and analyzed to make courseware. The courseware uses vivid and intuitive graphics and tables. To make the parents clear at a glance, so that all the parents of the students can not only see the fascinating speakers, but also see the visual image charts, which is very kind and the effect is also predictable.

Thirdly, it enriches students 'learning and education content. With multimedia, students' learning content is greatly enriched. Classes in class, thought class, morning meeting can use the video resource library of Yuzhi Information Network according to the actual class. Or online video programs on the Internet, selectively choose their own programs to play some educational movies.

3. "Clean Classes" has changed the teaching methods of teachers

First, it changed the way teachers prepare lessons. The implementation of "Dustless Class Communication" has prompted teachers to "change pens", from the original chalk board book to brushstroke and hand touch input, and to achieve hypertext from pure text. What's more important is the sharing of teachers' lesson preparation resources. Teachers can prepare lessons by designing and making courseware in the school's electronic lesson preparation room. Of course, they can also prepare lessons and make courseware in their own homes, and upload and download information through online neighbors in the local area network. You can also upload your lesson plans, courseware, etc. directly to the lesson center or courseware center of the school website at home (if you have a computer at home and have Internet access). On the one hand, it can be used by yourself and shared by other colleagues on the Internet. A more direct and faster way is to directly search through the Internet for various useful resources such as lesson plans, courseware, or papers needed for your education and teaching, and then further process and organize them for my use.

Second, it changed the teachers' teaching methods. Multimedia-assisted teaching is used in classroom teaching, which can make the teaching activities integrate information functions such as text, images, animation, etc. The images are clear, dynamic, and the amount of information is large. Realize large-capacity, multi-information, multi-interest and high efficiency of classroom teaching. Addition within 20 is a difficult point for first-year students. Many teachers use self-made multimedia courseware to vividly demonstrate the process of mathematical knowledge. At the same time, let students talk about thinking methods through courseware, and During the exercise, the students were counted by vivid animals, and how many methods did you use to calculate? Let the students talk about his own simple methods. Through this method, the key points and difficulties are effectively broken through to stimulate students' interest and achieve better results.

The use of supporting multimedia-assisted teaching software for teaching can mobilize and stimulate students' interest and internal potential in all directions, and actively participate in the teaching process; at the same time, optimize the teaching process, help broaden and thicken the cognitive foundation of students, and form migration and creation And practical ability. First of all, these supporting teaching resource libraries are exquisitely designed to meet the characteristics of students. From the beginning, they attract students into learning situations and actively participate in learning through vivid and vivid dynamic images and color-changing images and text. For the key and difficult points in the teaching, you can use the image and intuitive effects to display the key and difficult points of the teaching through animation simulation, video frame grabbing, background sound imitating, graphic concatenation, and problem display; through screen display, switching, pause, Steps such as blinking, combining, and repeating achieve the effects that were difficult to achieve in the past, exercise the thinking quality of students, and provide vivid and realistic teaching situations.

In addition, in classroom teaching, the use of the powerful interactive function of the low-light quantum environmental protection teaching system, from easy to difficult, layered design exercises, implementation of layered teaching, to provide different services for different objects, it allows students to meet their needs According to the actual situation, choose the order, progress and content of learning flexibly. You can also use its interactive function to receive information from students in a timely manner, analyze and judge, induce students to think and strengthen their memory, induce them to find and find errors, and finally get correct conclusions. After the student answers the question, the teacher clicks the button, and the computer will display various encouraging languages ​​or actions. If the student answers incorrectly, the computer will also display "You are allowed, please try again" to make the student interested in learning Confidence doubled.

Third, change the method of counseling and correction. The video display stand is equipped to facilitate teaching more effectively. First of all, the attention of younger students is easily distracted. I often can't find what you are talking about. With the help of the video display stand, the content of the lectures can be placed on the stand for students to watch and learn while watching. The effect is very good. Especially for the homework explanation, as long as the student ’s homework is placed on it, then the student will be clear at a glance, the homework format, right and wrong, etc. In art class, it can be used to comment on or appreciate students' works. In writing class, it can be used to guide students to write. Teachers first write on it to let students see the font, structure, and points of attention. Then students write their own, and after writing, they can get comments on the video display. This effect is better. The students are easy to grasp and the characters are written to meet the requirements. In addition, you can also use it to display real objects. As in mathematics classes, put on a set of learning tools, etc., let students speak while clarifying the calculation. We can use the video display stand to increase student interest. For some of the more difficult topics in the textbook, let the students who have done well be the interpreters and talk about how he did it. Then he pulled up the camera on the display and pointed it at the face of the classmate, letting him be the host on TV, explaining how he did it. The other students watched their companions on TV, and they were all interested and listened attentively. And students are all eager to try this kind of activity, use their brains when doing problems, practice hard, and want to go back to TV. This is much different than standing on the seat, and the boring knowledge is not boring.

Fourth, it changed the way teachers and students learn computer knowledge and skills. Installing simple multimedia equipment in the computer room is convenient for instructing students to learn computer knowledge or conduct computer training for teachers. Because computer learning and training are focused on practice, understanding of computer knowledge and mastering of skills must be achieved through the real participation of learners, and it is possible to make them feel. Through personal practice, they will eventually be internalized into their own skills. And usually in standard multimedia classrooms, learners can only watch the big screen because the learners do n’t have computers to operate. As the lecturer ’s teaching progress, watch and listen, for learners, such training It is almost a "talk on paper", some content is understood, but I really want to operate it on the computer, and I am at a loss. To solve the above contradiction, Wuzhifeng installed simple multimedia in the computer room to let students or accept Trained teachers sit at the computer to receive training. Teachers in class can use large-screen color TV to demonstrate the operation process. Learners can practice while listening and watching, and the learning effect is significantly improved.

4. "Clean Classes" has changed the way students learn

First, let students become masters of learning. Network-based multimedia devices make student learning more flexible and effective. Teachers, as the instructors of student learning, truly participate in learning activities together with students as learning partners and members of the learning community, and jointly explore ways to solve problems. Acquiring knowledge and ability together, students' learning initiative and learning enthusiasm are fully and effectively exerted, and the learning effect is obvious

Second, let the Internet be the second classroom for students. The rapid development of the Internet has changed people's lifestyles, working methods, and people's learning methods. Can the mastering of network knowledge quickly and effectively retrieve the information they need through the network, solve practical problems, and become An important criterion for measuring the information literacy of modern people. On the other hand, while the development of information technology is drastically unavoidable, it is inevitable that there will be a lot of sand and sand. It is undeniable that there are a lot of content on the Internet that is not conducive to the healthy development of students ’physical and mental health. . How to treat the Internet correctly, and how to make the responsibility of guiding students healthy online to fall to the shoulders of every educator in Wuzhifeng.

5. "Clean Classes" improves school management methods

Information technology has brought convenience to school management.

First of all, with the electronicization of school teachers ’lesson preparation, the school ’s paperless office is put on the agenda. The school will also check the teacher ’s plans, teaching plans, etc. through the network. In advance, each teacher is required to pass online neighbors The checked materials are sent to the folder of the designated computer, and the computer is turned on to check the teacher's relevant materials. At the same time, the results of the inspection are published on the school website in the form of an announcement.

Secondly, in order to understand the use of multimedia equipment by the relevant teachers after the installation of "Dustless Class", Wuzhifeng conducted professional training for school teachers, which made them have a better understanding of multimedia teaching and improved teachers ’ Teaching level and teaching ability.

The benefits brought to the school by the "dust-free class class pass" are obvious. From the perspective of economic investment, the cost-effectiveness of equipping the "dust-free class pass" in the class is relatively high, and it costs less than half of the ordinary electronic whiteboard The price, the effect achieved far exceeds the electronic whiteboard, and this set of equipment also has the advantages of simple structure, convenient use, no dust and no pollution. There is no need to install a dedicated projection screen, and its subsequent maintenance cost is extremely low compared to electronic whiteboards, especially for regional schools with less developed economic conditions, which is more popular. I believe that Wuzhifeng "no "Dust class class pass", has a very strong vitality.
