I learned a lot this computer week. During this period, I mainly completed three aspects of study: first, I listened to the teacher's lectures carefully in the first week, learning methods and experiences; Second, study the teaching materials carefully and listen carefully in class. Teachers comment, point out shortcomings and maintain advantages. The third is to sum up the exchange experience.
This internship made me feel a lot. On the one hand, because the information technology course is still a new course, there are not many teaching cases for reference. Only when teachers delve into textbooks, study teaching methods and prepare lessons carefully can students learn and master the correct methods in class. When I really went deep into the classroom for the first time, there were many problems that I didn't learn and encountered in normal schools, especially the new course of information technology, because the information technology course is different from other traditional disciplines, and it pays attention to students' practical operation, independent learning and practical ability. Students usually have great curiosity and interest when they are exposed to new things, especially for computers, an increasingly important tool. At this time, teachers should be good at grasping students' curiosity and cultivating students' interest and motivation in learning.
The ancients said: the knower is not as good as the knower, and the knower is not as good as the knower. Interest is an important condition for students to learn. Interest is the ladder of learning, and interest is full of desire and motivation. So how can we stimulate students' interest in learning? In information technology class, especially in theory class, students sometimes don't pay attention to the lecture or don't understand the meaning. Therefore, our teachers must study teaching materials according to the characteristics of students and refine the key points and highlights of teaching. Around this point, we can use easy-to-understand teaching language and appropriate metaphors to have a good theoretical lesson, so as to achieve better results.
For example, when I was studying WORD, a WORD processing software in the first class, I compared the blank file and input method of Word with the paper and pen commonly used by students, so that students could understand that writing with a computer is as convenient as writing with a pen and paper, with more functions and functions. In this way, in the absence of machine demonstration, students can understand and know WORD, master the general operation methods, and achieve the expected purpose. Of course, the information technology course pays more attention to letting students explore practical operations on the computer. In the curriculum, the computer class is twice as long as the theory class.
Of course, computer time is not blindly operated with students themselves. At first, the teacher should personally demonstrate the operation process, and let the students refer to the operation method through the play of teaching software. Similarly, because there are many ways to achieve the goal in the operation process, teachers should not be bound by the teaching of one method, but also guide students to find other ways to achieve the results, cultivate students' ability of independent learning and hands-on inquiry, and teachers should encourage them from time to time to enhance students' self-confidence and have a stronger interest in computers. This is my profound experience in this internship. The experience during this period has a very important role and enlightenment for our future work. After all, this is an essential process from normal students to teachers.

The two-week software course passed quickly. Learned CorelDRAW and Photoshop, and did some corresponding exercises, such as logo design, business card design, advertising page design and so on. This has a good learning process for us from understanding to contact.
Coreldraw is a vector graphics tool software, which provides designers with many functions such as vector animation, page design, website production, bitmap editing, webpage animation and so on. It contains two drawing applications: one for vector drawing and page design, and the other for image editing. This drawing software brings powerful interactive tools, which enables us to create various dynamic special effects and real-time effects of dot matrix images in simple operations-without losing our current work. Coreldraw's omni-directional design and web page function can be integrated into our existing design scheme, which is full of flexibility.
Photoshop is a graphic image processing software which integrates image scanning, editing and modification, image production, advertising creativity and image input and output. It has a wide range of applications, involving images, graphics, text, video and publishing. Among them, graphic design is the most widely used field of Photoshop. Whether it is the cover of the book we are reading, or the posters and posters we see on the street, these graphic prints with rich images basically need Photoshop software to process the images. Photoshop also has a powerful image modification function. Using these functions, we can quickly repair a damaged old photo, and also repair defects such as spots on people's faces.
In the first week, we learned the similarities and differences between the two software interfaces, such as the same general layout, menu bar, toolbar and drawing area. If you need to change the difference, Photoshop has a layer panel, where you can see the layers, and you need to click the layer you want to modify to change it. Coreldraw can directly click on objects to make changes, and finally you can group them, so you don't have to worry about moving the whole into a single object. Then I did some simple logo design and business card design with Coreldraw. My logo design is symmetrical color stripes. First, I draw curves with Bessel tools, and then I convert objects into surfaces. Now with the interactive contour drawing tool, the business card design mainly changes its texture, and then I fill it with shading. In the second week, I mainly used Photoshop to design a single page of an advertisement. It's not too difficult. Search the materials first, and then make a frame, collage, retouch and fill the imitation stamp tools.
After two weeks of study, I learned how to use CorelDRAW and Photoshop. Although I can't be a software expert, I am also a beginner. Although I encountered some difficulties, I really benefited a lot from asking what to do. Although the course is over, the end of my study will not stop. I will continue to work hard.

During the week-long intensive computer training, we have a deeper understanding of the basic knowledge and development history of computers.
The birth of electronic computer is an important milestone in the development history of science and technology, and it is also one of the greatest inventions of mankind in the 20th century. The development course of just half a century shows that information processing is one of the fastest developing and most widely used fields of science and technology in the world today. Today, computers have entered all walks of life and thousands of households, resulting in enormous social and economic benefits. From word and spreadsheet processing to database management, from scientific calculation to multimedia application, from local area network to remote communication, from office automation to information expressway, computer applications are everywhere. The informationization of society and the universal application of computers have penetrated into all fields of human society, and profound changes have taken place from economic base to superstructure, from production mode to lifestyle. The popularization and application level of computer technology has become an important symbol to measure the degree of modernization of a country or region. In today's information age, it has become an urgent need for people to learn computer knowledge and master computer applications.
The first fully automatic electronic computer ENIAC was successfully developed in 1946. Since its birth, the development of computers has gone through four stages:
1.1946-1957 the first generation of electronic computers characterized by the use of electron tubes. The basic logical components of electron tube computer are electron tubes, mercury delay lines or magnetic drums for storage, and magnetic tapes for external storage. Its characteristics are: slow speed, poor reliability, huge volume, high power consumption and expensive price. The programming language is mainly machine language, and later there is assembly language. The debugging of programming is very complicated, and its use is limited to the scientific calculation of military research.
2. 1958-1964 The second generation electronic computer replaced the electron tube with transistors and added floating-point operations. The second generation computer added floating-point operation, which made the absolute value of data reach dozens or hundreds of powers of 2, and made the computing power of electronic computers leap. At the same time, using transistors instead of electron tubes greatly reduces the volume of the second generation electronic computers, prolongs their life, reduces their prices, and creates conditions for the wide application of electronic computers. At the same time, computer software technology and technology have developed greatly, and the concept of operating system has been put forward. Besides assembly language, advanced programming languages such as FORTRAN and COBOL are also developed, which greatly improves the working efficiency of computers.
3.1in April, 964, the IMB360 system came out and became a famous representative of the third generation electronic computer using integrated circuits, which is a kind of computer using integrated circuits. 1958, when the world's first integrated circuit was born, it only included a transistor, two resistors and a resistance-capacitance network. Later, the integrated circuit technology became more and more perfect, and the number of components contained in the integrated circuit doubled at the rate of 1-2 years per year. By the early 1970s, most circuit components had appeared in the form of integrated circuits. Even, millions of electronic components can be integrated on a chip about the size of a fingernail 1 cm2. Because it looks like a small piece of silicon, people often call it a chip. Compared with transistors, integrated circuits have developed rapidly because of their smaller size, lower power consumption, higher reliability and lower cost.
4. In 1970s, the adoption of VLSI and VLSI marked the beginning of the fourth generation computer. Since 197 1, the basic logic components of computers have gradually adopted large-scale integrated circuits.
In modern society, computers have been widely used in military, scientific research, economy, culture and other fields, and become an indispensable helper for people. In the field of scientific research, people use computers to carry out various complicated operations.
Calculation and processing of a large number of data, such as satellite flight trajectory, data processing in weather forecast, etc. Because the computer can perform calculations at high speed and accurately, and it takes a few days, years or even a lifetime to complete the calculation task, the computer can complete it in a short time.
In schools and * * * institutions, a lot of statistics and analysis of data are involved every day. With computers, work efficiency has been greatly improved. In the factory, the computer provides an effective auxiliary means for engineers to design products. Nowadays, when people design buildings, computers can automatically process and draw various design drawings as long as they input relevant raw materials. In production, the computer is used to control the automatic operation of the production process, such as temperature control, voltage and current control, so as to realize automatic feeding, automatic product processing and automatic product packaging.
Nowadays, people's communication is becoming more and more, which requires faster and wider transmission of information, and "Information expressway" came into being. Among them, the Chinese meaning of Internet is: an international interactive network with tens of millions of users. As long as users connect their computers to this network, they can contact the whole world, and you can get all kinds of information on this system, such as electronic news, e-books and emails. , sitting at home. Computers are entering the family, which has brought profound changes to people's lifestyle. The washing process of automatic washing machine is controlled by computer, which saves people the trouble of washing. The operation of air conditioner and refrigerator is controlled by computer according to the change of temperature, which brings a cool world to people. In some advanced countries, all kinds of household appliances are connected through the Internet, and people realize the automation of housework through voice control and remote control, which greatly improves people's quality of life.
During the one-week study, I have a deep understanding of the basics, history and development fields of computers. Further understanding of the importance of computers in social development has benefited a lot. Finally, I sincerely thank the teacher for his careful guidance!
