Media refers to the carrier or representation of information. Multimedia technology refers to the use of computer technology to text, sound, graphics, images, animation, video and other media information together and make it a logical link. Multimedia teaching refers to the application of multimedia technology in all aspects of classroom teaching. Classroom teaching is the most important and basic form of activity in school education. Students acquire knowledge, accumulate qualities, improve ability and achieve development mainly in the teaching process. Students acquire skills mainly in practical teaching. Practice teaching can be set separately, can also be combined with classroom teaching interspersed among them. This article argues that improving students' abilities is one of the most important goals pursued by the teaching process.
After serving as a teaching supervisor in recent years, I have learned through classrooms that 90% of classrooms use multimedia teaching. From the situation of attendance, multimedia classroom teaching design, it is necessary to arouse the attention of teachers .
Teaching design is to achieve certain teaching objectives, according to the subject of the course content, student characteristics and environmental conditions, the use of teaching and learning principles for students to plan learning resources and learning activities . Teaching Design Based on communication theory, learning theory and teaching theory, the author uses the viewpoint and method of system theory to analyze the problems and needs in teaching so as to find out the best solution. Instructional design is a bridge or intermediate link between teaching theory, learning theory and teaching practice .
Instructional design is a new discipline originated from the United States in the 1950s. It has a far-reaching impact on overseas education in schools, business training and military training. 1987 "foreign language teaching" magazine published the first article on teaching design, instructional design began to be introduced into the country. In recent years, the teaching design has become one of the main courses in the domestic colleges of technical education in education, and some colleges and universities have established related educational technology research institutes. Instructional design in the education sector is gradually becoming a hot spot in teaching and research .
The following will discuss the construction of digital teaching resources and the ability to develop students, analyze the pros and cons of multimedia teaching, explain the basic skills of teaching design, with a view to improve the quality of multimedia teaching to provide a reference wine course in hk.
1. Digital teaching resources construction and the cultivation of students' abilities
1.1 The source of digital teaching resources and construction principles
Digital teaching resources refer to digitized multimedia teaching materials, including digital slideshows, projection, audio and video, and electronic courseware. It can be used for classroom teaching in multimedia classrooms, and also for online teaching under the network environment. The sources of digital teaching resources in general there are three ways: ① the existing teaching resources for digital transformation; ② teachers and students create electronic works; ③ professionals developed by the construction of resources.
The construction of digital teaching resources should follow six basic principles: ① teaching principle: resources should be able to meet the needs of teaching and learning; ② scientific principles: resources should be able to correctly reflect the principles of scientific knowledge and modern science and technology; ③ open principle: should Ensure that teachers and students can put their electronic works into the library at any time and from any place. (4) Principle of universality: Under the corresponding technical standards, resources should be applicable to different teaching situations and forms Learning; ⑤ hierarchical principles: resources should be implemented modular management, so that learners through the use of different levels of resources and reorganization, to maximize the effectiveness of resources; ⑥ economic principles: should be the least investment in the development of high-quality, High-performance teaching resources.
The author follows the above principles, and builds digitized teaching resources for the course of "Advanced Design System". The "Research and Practice of Modern Teaching of Mechanical System Design" won the third prize of teaching achievement in Hebei Province in 2000, The construction of excellent courses and the digital teaching resources that have been built up until now are still the basic contents of the achievements. The only difference is that they have accumulated and added new contents that are keeping pace with the times. In fact, the teacher in the classroom teaching is re-processing of teaching content, and then understand, re-play, and then create the process. The same teaching content, no matter how many times spoken, each time there will be a new experience, new understanding, new feelings. The same is true of digital teaching resources. For example, a teacher's multimedia courseware for producing a course is by no means a month or two. It takes two semesters, or even semesters.
1.2 ability to distinguish and classification
The principle of teaching is the first principle of building digital teaching resources. Teaching and learning The most important need for resources should be to improve students' abilities. Knowledge, quality, skills and ability are closely linked, but also have obvious differences. Knowledge is the knowledge and experience gained by people in practice. Quality is the basic condition necessary for completing certain activities. Ability refers to the subjective conditions necessary for the successful completion of an activity. Skill refers to what can be obtained through practice to accomplish certain tasks Action system. Human psychological activity is developed in the combination of genetic quality and environmental education. It can be said that quality is the physiological condition for the development of human psychology. Ability is the psychological condition for the successful completion of human activities Dr protalk.
Skill is a kind of physical activity that can happen skillfully. You must learn it by yourself and practice it to master the skill. And once you stop practicing, skills will quickly become unfamiliar. Ability is developed on the basis of skills, but also become an important condition for the smooth mastery of skills. Generalized abilities include qualities and skills.
Ability according to the function can be divided into: cognitive ability, operational ability, communication ability, imitation ability and innovation ability. Cognitive ability is the ability to receive, process, store and apply information. Observation, perception, memory, attention, thinking, and imagination are all considered cognitive and often intellectual. Operational ability is the ability to manipulate, produce and exercise, ability to work, artistic performance, physical exercise ability, experimental ability are considered operating ability. Communication ability is the ability that people show in the communication activities. The ability of organization and management and verbal infection are all considered as communicative competence. Mimicry refers to the ability to learn a variety of knowledge by observing others' behaviors and activities, and then responding in the same way. Innovativeness refers to the ability to generate new ideas and new products.
The objectivity of knowledge is biased; because ability reflects the most basic and stable psychological characteristics of personality, the subjectivity of ability is biased. Ability is the mental and physical energy obtained through repeated training in the process of using intelligence, knowledge and skills. The combination of various abilities, the ability to change the quality of talent known as talent. The ability to highly develop the ability to accomplish tasks creatively is called genius. Cognitive ability and operational ability are closely linked. Cognitive ability must have operational ability, operational ability must have cognitive ability. Communication skills include cognitive ability and operational ability. Imitation ability is the basis of innovation ability, which is one of the most important and valuable human ability.
On the ability of the classification, from the perspective of improving the ability, the author will be divided into four categories of thinking, language, behavior and combination, as shown in Figure 1. The ability of thinking includes: observation, memory, comprehension, judgment, analysis, comprehensiveness, imagination and so on; language ability includes: language speed, language use, word combination, occasion application, generalization; Competence, Sensitivity, Strength, Stamina, Speed, Listening, Attention, Perception, etc. Combinations include: Combinational Competence, Combinatorial Competence, Competence in Thinking Behavior, Competence in Thinking Language, and Competence in Speech Behavior. Thinking ability, language ability and ability of the three are interrelated. The ability of thinking and combining play a leading role in this, language ability and ability can promote the continuous development of thinking ability. By specialized training of various abilities can be greatly improved The new PolyU e Admission portal is a one-stop platform aimed at handling applications of university degree courses. With PolyU e Admission, the application process is refined into three simple steps.
