1, information consciousness: We are in the information age of information explosion, and the growth of information has not directly enhanced our "information consciousness". Information consciousness mainly reflects a person's information sensitivity and comprehensive ability and quality of information value judgment.
2. Computational thinking: Its connotation refers to a series of thinking activities produced by individuals in the process of forming problem-solving solutions by using thinking methods in the field of computer science. It is mainly manifested in four aspects: "formalization, modeling, automation and systematization".
First, regularization. In information activities, we can define problems, abstract key elements and analyze the relationship between them in a way that computers can handle.
Second, modeling. Establish a model of information processing, organize data reasonably, and form a solution to the problem by judging, analyzing and synthesizing various information resources and using reasonable algorithms.
Third, automation. Explore the process and method of using information technology to solve problems, and realize the automatic operation of problem-solving scheme.
Fourth, systematization. Form a systematic process to solve problems and migrate it to other related problem solving.
3. Digital learning and innovation: Digital learning and innovation are the key elements of the competitiveness of modern society. Digital learning and innovation refers to the ability of individuals to effectively manage the learning process and learning resources, creatively solve problems and form innovative works by evaluating and selecting digital resources and tools.
4. Information society responsibility: Its connotation lies in that members of society need to correctly understand the relationship among people, information technology and information society, abide by its rules and requirements, promote the development of information society, shoulder the responsibility of members of information society, abide by the moral and ethical norms of information society, abide by the public norms of real space and virtual space, and establish the values of the information age with an active and open mind and rational judgment.
Four core concepts of information technology discipline
1. Data is a symbolic record describing things, a carrier of information, and an object recognized, stored and processed by computing tools such as images, sounds, characters and values.
2. An algorithm is a description of the steps to solve a specific problem and a series of clear instructions to solve the problem. Accurate algorithm is the premise of effective calculation for computing tools.
3. Information system is a man-machine interaction system composed of users, hardware/software facilities and data. Reasonable design and application of information system can better perceive, transmit, process and apply information.
4. Information society is a social form that carries out socio-economic, political and cultural activities by creating, distributing, using, integrating and processing information. Among them, members of society creatively and efficiently use information technology as a means for individuals or organizations to gain higher survival and development advantages.
