Analysis and Design of Teaching Content
The second section of the first chapter of "Fundamentals of Information Technology" in Senior One of Education Science Press. Because this content is theoretical, if it is only taught by the teacher, students may feel boring, so I am going to cite phenomena under the guidance of the teacher for students to discuss, then summarize and gain knowledge.
Teaching object analysis
Last class, the students had already understood the basic characteristics of information and had a certain understanding of information, but their understanding of "information technology" was very vague, and information technology was generally equated with computer technology. Making students understand information technology is a key point of this course. In the teaching content of experiencing the development of information technology, the key point is to let students experience "voice technology", and other items are only briefly introduced.
Teaching objectives
Understand the development history of information technology and the relationship between various information technologies; Experience the development and changes of information technology; Guide students to be kind to information technology and use it healthily.
Emphasis and difficulty in teaching
Look at the development history of information technology from five aspects; What is the development trend of information technology? Rational use of information technology.
Teaching environment
Multimedia computer network classroom
Teaching strategy
Teachers take the initiative to learn and acquire knowledge through the process of expelling phenomena, discussing and analyzing, and summarizing.
teaching process
First, the development history of information technology
information technology
All technologies related to information acquisition, processing, expression, communication, management and evaluation can be called information technology. From the development history of human society, information technology has experienced five information technology revolutions.
1) Language use: an important symbol of the evolution from apes to humans;
2) Creation of characters: it is the storage and transmission of information that breaks the limitation of time and space for the first time;
3) The invention of printing provided a more reliable foundation for the accumulation and dissemination of knowledge;
4) Invention and popularization of telegraph, telephone, radio and television: further breaking through the limitation of time and space;
5) Popularization and application of computer and modern communication technology: to push human society into the digital information age.
The first generation: 1946- 1958, electronic computer;
Second generation: 1958- 1964, transistor electronic computer;
The third generation: 1964- 1970, integrated circuit computer;
*:1971-1LSI computer of the 1980s;
Fifth Generation: Up to now, intelligent computers.
Second, the development trend of informatization
Information technology has a long history, and it will develop in the direction of humanization and popularization, that is, information technology is increasingly symbolizing people's needs and usage habits.
The specific manifestations of popularization:
1) More and more friendly man-machine interface.
A top ten human-computer interface devices in the 20th century-megaphones, touch-tone telephones, steering wheels, magnetic cards, traffic lights, crt, remote controllers, LCD, barcode scanners, and mouse/GUI;
B, dos operation interface and gui operation interface: humanized interface and personalized design;
C virtual reality technology (produced at the end of 20th century);
Three-dimensional realistic virtual environment: three-dimensional graphics generation technology, multi-transmission sensory interaction technology, high-resolution display technology.
"3i" features: strong "immersive" immersion; Friendly human-computer interaction; Stimulate people's imagination.
Classification: virtual reality technology (such as virtual visit to the Palace Museum), virtual reality technology (such as virtual reality environment generation, virtual design of Boeing 777 aircraft).
D, voice technology;
Speech recognition technology (ASR)-A technology that converts human voice signals into text information that can be recognized by computer, so as to recognize the speaker's voice instructions and text content.
Speech synthesis technology (TTS)- a technology that converts text information into voice data and plays it out through voice.
The application of voice technology can be divided into three aspects: desktop application, network/telephone system application and information appliance application.
E. Intelligent agent technology: usually, it can actively complete certain tasks according to people's needs, which is mainly used for automatic binding and filtering of information. Such as "robot" or "*" programs in search engines.
2) More and more personalized functional design.
3) The cost performance is getting higher and higher.
For example, the size of computer memory chips changes from 1mb at the beginning to 32mb, 64mb, 128mb, 5 12mb and so on. (mb stands for the unit of storage capacity in the computer). The storage capacity of a computer is calculated in bytes.
The units commonly used in computers to express capacity are: byte (B), kilobyte (kb), megabyte (mb) and gigabyte (gb).
The transformation relationship between them: 8 bit =1b; 1kb = 2 10b； 1mb = 2 10kb； 1gb = 2 10mb； 1tb=2 10gb
Third, rational use of information technology.
Facing the development of information technology, we should understand objectively, foster strengths and avoid weaknesses, and give full play to the role of information technology.
Forms of cyber crime:
1) Entering other people's computer facilities through the Internet without permission, cracking other people's passwords and using other people's computer resources;
2) spreading computer viruses to other people's computer systems through the network; Spying, stealing, tampering with or deleting state secret information;
3) Business spies steal, tamper with and delete business secrets and computer programs stored by enterprises and institutions;
4) illegal transfer of funds; Stealing other people's bank deposits and committing various financial crimes.
5) Use the Internet to spread harmful information, slander, insult and intimidate others, create rumors, spread false news, disrupt social order, spread violent, horrible and superstitious works, and poison young people; Blasphemy of religion and destruction of national unity; Carry out cultural and ideological infiltration activities.
