Mathematical Social Practice Report

During the summer vacation, I spent two weeks of social practice at Hezhou Middle School.
Hezhou Middle School is the oldest middle school in Hezhou City and Guidong area. The campus is flat and broad, and the open sun is quiet. It is a good place to teach and educate people. It has been 83 years since its establishment in 1921. Hezhou City has a rigorous academic study and excellent academic style. It has attracted students from several counties in Guangxi and Guangdong to study. It has trained more than 25,000 students and has alumni throughout the country and overseas. Many alumni have become leading cadres at the party, government, and military levels, and many alumni have become famous experts and scholars with accomplishments. In 2004, it passed the “Autonomous Region High School Level Assessment” and was rated as a first-class school. The application of the computer has just started in Hezhou Middle School, but it has made everyone's computer awareness increase, the development of audio-visualization has developed rapidly, and the quality of teaching has also increased rapidly. In 2000, the school built a computer room with only 40 computers. It can be said that compared with the city, the equipment here is relatively simple.
After the land acquisition in the previous years, the school covers an area of ​​150.2 mu, becoming the largest secondary school in Hezhou. In 2003, the company invested 1.25 million yuan to build a five-storey office complex with an area of ​​1,750 square meters. It opened a language room and a multimedia classroom. In 2004, the company invested 1.45 million yuan to build a new four-story teaching building with 20 classrooms, and two lecture-style multimedia lecture halls and electrified classrooms.
The computer teaching of the middle and high school students in the whole school is carried out here. The textbooks used by the students are: "Information Technology" published by Guangxi Science and Technology Press. The textbook covers all the test sites of the National Computer Level Examination, including computer basic knowledge, office office. The use of software, the use of digital devices, animation, web page creation, etc.

In the face of this high-starting textbook, how do you react?
I talked to teachers and students separately.
It is learned from the students that a large number of students are studying with a serious attitude. However, many students use computers only at the school. The students have limited foundation and there are fewer computer courses in the school, so the effect of learning Not obvious.

The teacher said that in actual teaching, it is impossible to completely follow the textbook teaching. So how does the teacher skillfully teach the students in this situation? For this question, I asked the computer teacher and learned some teaching experience from him:

Due to the limited ability of students to accept and the lack of a solid computer foundation, the content of the new lesson should not be too much, and it should be consolidated with a large number of exercises. Another important aspect is that beginners have poor self-control ability, and the efficiency of lectures is very low. They often have to carry out repeated individual counseling in the classroom.

From the perspective of teaching methods, task-driven learning for students is an ideal method. Students are still unfamiliar with computers, so that thinking in this area is not active enough and innovation is limited. If the teacher is demonstrating anything in the course of teaching, the student will copy your presentation invariably, which is very unfavorable for both understanding and innovation. Task-driven can stimulate students' interest, and the fuzzification of task rules is conducive to students' creativity. If task-driven in the teaching of new courses, students can explore and learn by themselves, which is conducive to understanding and mastering new lessons.

Another important teaching method is to let students teach students. For example, a new lesson is assigned to a task, which is usually impossible for most students. If a small number of students are completed, they can be taught. In general, students have a fresh sense of this teaching method, and students are more concerned about the situation of other students. This teaching method makes students have a deeper memory of knowledge.

In addition, the quality of classroom discipline directly affects the teaching effect, so it is important to control classroom discipline. Because many students who graduated from our major have chosen a teacher profession, it is helpful to learn from the teachers who have rich teaching experience. After listening to the teacher several times, I felt that I had benefited a lot.

While Hezhou Middle School is working hard to create a garden-like educational environment, it is also creating a strong atmosphere for faculty and staff to learn computers and use the Internet. The school built a broadband Internet in 2003, which caused a fundamental change in the networking of Hezhou Middle School.

The Internet has evolved from the initial research network and has now evolved into a highly commercialized mass network, marking the beginning of a new “new era of the Internet”. But network security or information security is accompanied by the birth of the Internet. The Internet is like a double-edged sword. It brings convenience to people's lives and is also a tool used by people with bad intentions.

One day, when I went to the computer room with the teacher, there was always an annoying report in the firewall log of a computer inside. I received hundreds of messages in half an hour, and the report showed that several IPs were trying at the same time. After connecting the NetBios-SSN[139] connection of the machine, the teacher arranged me to deal with this problem. I immediately surfed the Internet and found out in Sina's article "Network maintenance firewall makes the worm virus prototype": If an IP connects to the NetBios-SSN[139] connection of the machine several times in a row, it is time. The interval is short and the connection is frequent, so the computer listed in the log is infected with the "Nimda virus." A feature of computers infected with the "Nimda virus" is that they search for all available shared resources in the local area network and copy the virus into a shared folder with full control permissions to achieve virus transmission. purpose. It can be seen that many users of the local area network are infected with the "Nimda virus".

The truth is white! No wonder computers are harassed. Understand the reason, I will post to the forum immediately. And shared a worm killing tool and a Trojan horse tool. If the real medicine is gone, the log of the firewall is much quieter.
The popularity and promotion of computers will enable people in the 21st century to obtain more, faster, and more information in their lives, studies, and work. If you teach and learn in the traditional way in teaching, it is obviously not able to adapt to the requirements of the times. Multimedia teaching came into being. In the summer, I practiced, including assisting the chemistry group teachers in making multimedia teaching courseware.
For most teachers to make their own teaching software, the software requirements on the one hand do not require special installation, almost all computers; on the other hand, more importantly, easy to learn, convenient and practical, not particularly troublesome . Therefore, as far as I know, if it is for teachers to use, most of them use PowerPoint, and the effect is really good. In general, the function of PowerPoint is not as good as Authorware, but it should be said to be easy to handle and cope with in the daily auxiliary teaching. From the technical time of input and the actual effect of the application, it can be said that it is very economical. In the process of learning how to use PowerPoint to create courseware with my teacher, I refer to the introduction and improvement of the Chinese version of the office and the latest multimedia courseware teaching and learning. These two books have high reference value. In the actual production process of courseware, we often choose and prepare some films, pictures, animations, sounds and other materials, and how to use these materials flexibly and freely becomes the key to improving the quality of PowerPoint software production.

After the completion of the courseware production, the teacher's affirmation surprised me a lot. After a few nights, I have been communicating with the teacher and discussing the experience of making courseware. Since I have already studied the contents of the office at school, I have the opportunity to show my ability – from beginning to end, I taught a computer started teacher to make a simple courseware. From the beginning of the text entry and acquisition, the graphics are processed and processed, and the music and motion are collected and processed. Although it is not very difficult, this has become something I am proud of.

Through the internship, I feel a lot:
First of all, I have gained a new understanding and understanding of computer use, computer management, and computer networks.
Secondly, this practice has provided me with a different learning method and learning opportunities, which has changed me from the traditional passive teaching to the active learning; from the rote model, to learning in practice, enhancing The ability to comprehend, innovate, and infer. Master the self-study method, form the overall model of engineering theory, and make work, study, and life all enter the systematic process; the way of thinking is mature, the logic is standardized, and clear. The improvement of these methods is a lifetime benefit. I think this rare two weeks makes me really understand the basic rules of work and study. I deeply understand the importance of teamwork and dare to show myself. Since I came here, my method of doing things has changed. The most obvious thing is that I have transformed the way of doing things. It turned out to be done after school. Now I am learning by doing. Self-study is very important, and there is no end to learning.

Moreover, in the time of practice, I have made a great change in my mind. In the past, when I was learning in school, the teacher always poured knowledge into our minds. I didn’t have such a strong desire for knowledge. Most of them forced them to learn. However, practicing here has made me deeply feel that my knowledge is too poor, and how important it is to strengthen my knowledge!

Also, throughout the whole process of this practice, I was in an atmosphere of solidarity and cooperation between leaders and teachers and teachers. I deeply realized that it is very important to maintain a good relationship with colleagues at work. I know that to do things first, we must learn to be human beings. We must understand the truth of being a human being. How to get along with others is one of the most basic problems in modern society. Technical deficiencies can be solved through the study of books, but the grasp of interpersonal relationships at work can not only be based on textbooks, but also requires more personal experience.
"A journey of a thousand miles begins with a single step." This short and substantial practice in the past two weeks has played a role in bridging the society. The role of the transition is an important experience in life and an important step for the future. Going to work has also helped a lot, and laid a solid foundation for me to go to the society. This is a valuable asset in my life.
