With the advancement of information construction in colleges and universities and the development of computer technology, network technology and multimedia technology, modern educational technology has been widely used in college teaching. The application of modern educational technology will promote great changes in teaching concepts, teaching methods and teaching environment in colleges and universities.
Modern educational technology has promoted the formation of open teaching mode. Through the interaction between teachers and students, we can discuss problems and answer questions, so as to find suitable teaching methods and learning methods. Teachers have changed from imparting knowledge to organizers and guides of students' learning knowledge, and students have changed from simply passively accepting knowledge to exploring knowledge independently, thus improving teaching efficiency and quality.
First, the classroom teaching under modern educational technology
Classroom teaching under modern educational technology refers to the combination of multimedia technology and traditional classroom teaching. As a teaching method, modern educational technology has become an important part of classroom mathematics. Symbols, languages, characters, sounds, graphics, images, videos and other information are comprehensively processed and controlled by multimedia computers, projectors, curtains, audio, etc., and organically combined and demonstrated with sounds according to teaching requirements to complete the teaching process. Multimedia teaching makes up for the deficiency of traditional classroom teaching.
In today's information construction, it is an important content of modern educational technology to introduce multimedia technology into classroom teaching. Compared with traditional classroom teaching, multimedia teaching has the following characteristics.
(1) The content is vivid and intuitive.
Information such as symbols, languages, characters, sounds, graphics, images and videos are comprehensively applied to teaching activities to solve problems that are difficult or even impossible to solve by traditional teaching methods. Colorful teaching content makes abstract knowledge clear and easy to understand, and makes teaching content vivid and intuitive, thus effectively improving teaching quality.
(B) to stimulate interest in learning
The vivid and intuitive teaching content of multimedia classroom is conducive to developing students' thinking, cultivating students' thinking ability, encouraging students to think positively, inducing students to analyze problems, and changing the boring and monotonous teaching form of traditional classroom teaching, thus activating students' thinking and stimulating students' interest in learning.
(C) High class time density
Through courseware demonstration, multimedia teaching is more expressive and appealing than traditional classroom teaching methods, and students can acquire knowledge quickly and efficiently. It reduces the time of writing blackboard books in class, improves the classroom density, greatly increases the teaching content in the limited classroom time, and effectively improves the teaching efficiency.
Second, the network teaching under modern education
With the rapid development of modern educational technology, the teaching process is no longer limited to the classroom. As a concrete embodiment of the application of modern educational technology in college teaching, network teaching has become an important basic teaching form. Network teaching not only breaks through the limitation of time and space, but also solves the problem of insufficient teachers and equipment.
Network teaching breaks the traditional classroom teaching mode and constructs a virtual classroom that breaks through the time and space constraints. Network teaching is an extension of classroom teaching, and it is a brand-new teaching form and method based on network environment and combined with modern educational technology such as computer technology and multimedia technology. Network teaching makes teaching resources available on the Internet and all over the world. Compared with traditional classroom teaching, online teaching has the following characteristics.
Wide coverage
With the development of network technology and the deepening of globalization. Internet has become an important information infrastructure in today's world. After just over ten years of development, the global Internet has covered more than 200 countries and regions on five continents.
Spanning time and space
Through online teaching, teachers and students have crossed the geographical distance. Even if the teachers and students are thousands of miles apart, the traffic is inconvenient and they don't leave home, they can complete the teaching process of teaching and learning. There is infinite overlap in time, so you can teach at any time, learn at any time, and do it repeatedly until you understand and accept relevant knowledge.
(3) Rich information
The Internet provides huge information resources for netizens all over the world. By using the Internet, people all over the world can search, exchange and enjoy information simply and quickly, so the Internet is a global world-class library. Network teaching can * * * enjoy huge and excellent teaching resources, and can constantly improve and enrich course knowledge information for students to download and learn. Through the network, learners can learn more relevant knowledge with the help of network resources while learning subject knowledge. Through analysis and comparison, a deep understanding of what you have learned is more conducive to digesting and mastering new knowledge and cultivating students' ability to collect and process information.
Teacher-student interaction
Through the online teaching platform, students can raise doubts and difficulties in the learning process, and students can discuss with each other or ask teachers to answer them. Even if teachers and students can't be online at the same time, they can have a delayed discussion through the online platform. Through communication and exchange, we can not only increase the affection between teachers and students, but also help teachers to understand the students' mastery of curriculum knowledge, find and improve the problems existing in the teaching process, thus improving the teaching quality.
Three. Concluding remarks
The application of modern educational technology has become an important embodiment of the development of teaching level in colleges and universities. As the development trend of future teaching methods, modern educational technology will have more and more extensive application fields and better development prospects. It is true that modern educational technology has its advantages and has played a positive role in improving teaching quality and teaching effect. However, modern educational technology still has many shortcomings. As university workers, we must persistently explore the road of modern educational technology, keep up with the development of society, constantly improve teaching methods, explore teaching methods and innovate teaching methods to meet the needs of social development.

Model essay on educational technology II
On Educational Technology Resources
With the rapid development of science and technology, the development of educational technology resources has amazed the world, and its advantages are becoming more and more prominent in modern education. This paper expounds the application of hardware resources, submarine resources, software resources, network resources, courseware resources, integrable ware resources and data communication in teaching and the relationship between these educational technology resources.
Keywords educational technology; Resources; Type; relationship
With the rapid development of science and technology, educational technology resources have also developed rapidly, especially the software resources among the three major resources (hardware, software and software), namely CAI courseware resources, network resources, integrable ware resources and data communication, have developed faster, and their advantages are becoming more and more prominent in modern education. The application in teaching will greatly change the traditional teaching methods and means, provide conditions for deepening educational reform and realizing educational modernization, and play a very important role in improving teaching quality and cultivating students' ability.
I. Types of educational technology resources
(1) hardware resources
Hardware resources refer to various teaching machines or equipment used for tangible and concrete information conversion. Hardware resources will not change the cognitive structure of the receiver in communication activities, but can promote the occurrence of communication activities, accelerate or delay the change of the receiver's cognitive structure, and realize the promotion function. Hardware resources usually exist in the form of objects. Hardware resources are the material basis for developing educational technology. Without hardware resources, educational information stored in software resources can not be presented or can not be presented completely. The information on tapes, disks and CDs cannot be directly perceived by students' senses; The information on slides, slides and movies can't be effectively observed by students in class.
(b) resources that can be submitted
Submittable resources mainly refer to theoretical systems and methods related to educational technology. Submersible resources are similar to hardware resources and are also an external support condition. The purpose of studying it is to discover the application characteristics of educational technology and construct a series of theoretical systems, so as to help recipients receive information quickly. As a comprehensive subject, educational technology has its theoretical basis and special theory. Potential resources are intangible, the theoretical conception, research results and implementation strategies of potential education, teaching psychology, information, communication and control. Potential resources are abstract, which are ideological things gradually formed and accumulated in the minds of teachers and students in the practice of teachers' own learning, teaching activities or cognitive activities, which can transfer some learners' learning experience to other learners and reduce repeated exploration activities. Therefore, seabed resources mainly reflect the migration function of resources. Hidden resources are the key of educational technology, which determines the selection of hardware resources, the compilation of software resources, the optimal combination of media, the proper use, the control of educational process, the feedback of information and the coordination of students' physiological and psychological activities.
(3) Software resources
Software resources refer to teaching materials designed by hardware, which are educational information and its carrier. In the communication activities of human beings, it is software resources that can really change the cognitive structure (cognitive field, emotional field and motor skill field) of the recipients and realize the changing function in the resources. Usually, we regard software resources as teaching materials corresponding to hardware resources. Software resources contain the specific content of education and are the necessary conditions for the implementation of educational technology. Without software resources, the work of hardware resources is meaningless, and it becomes passive water, rootless wood and unable to transmit any educational information. Software resources include conventional software resources, computer-aided teaching software resources, network resources and so on.
1, general software resources
Conventional software resources mainly refer to recorded educational information? Three pieces and two belts , namely slides, slides, movies, audio tapes, video tapes, etc.
2. Network resources
Network resources mainly refer to multi-level and remote online resource libraries such as campus network, local network, national network and international network.
3. Computer-aided teaching software resources
Computer-aided teaching software resources mainly refer to CAI courseware resources, integrable ware resources and intelligent learning software resources. Only courseware resources and integrable ware resources are discussed below.
(1) courseware resources
Courseware resources are computer software resources designed according to teaching objectives under the guidance of certain learning theories, which reflect certain teaching strategies and teaching contents. The basic models are drills and practice, guidance, consultation, simulation, games, problem solving and discovery learning. No matter what kind of courseware, it is an organic combination of two kinds of information: teaching content and teaching processing strategy. That is, all kinds of teaching information are prompted to learners; Various information and information processing used for diagnosis, evaluation, prescription and study guidance in the learning process; In order to improve learning enthusiasm, create learning motivation and strengthen encouraging learning evaluation information; Teaching strategies and control methods to update learning data and realize learning process control. Among the four elements of teaching activities (teachers, students, teaching materials and teaching methods), people (teachers and students) are the core. Courseware is closely related to teaching objectives, teaching strategies and learning theories, and it is the concrete embodiment of editors' thoughts and teaching methods. Courseware can't be modified after the finished product, nor can it be reorganized by teachers and students to adapt to their current teaching. It is suitable for the specific teaching objectives and specific teaching situations determined in advance. Some courseware completely matches the teaching materials, is closely related to the teaching syllabus, and is closely related to a certain version of primary and secondary school teaching materials. The courseware content is arranged according to the chapters of the teaching materials. It has integrity, fixity, specificity and closeness. The application of courseware can achieve teaching objectives according to certain learning theories and teaching strategies, and it can play a huge role in the teaching activities of teachers and students. However, courseware is determined in advance by teaching design, and its program is fixed, plot is stereotyped, modular, closed and comprehensive, which determines the scope of application in teaching activities, which is not conducive to giving full play to the personality and creativity of teachers and students, and is not suitable for the ever-changing classroom teaching reality, and is greatly limited.
(2) Integrable ware resources
Integrable ware resource is a teaching software system for teachers and students to use multimedia teaching information resources according to their teaching needs. The system is an organic combination of integrable ware library and integrable ware combination platform. The integrable ware combination platform can easily combine all kinds of teaching resources in the integrable ware library without programming, which is easy to learn and use for ordinary teachers. The integrable ware database includes five parts: multimedia teaching database, microteaching unit database, online environment resource database (online multimedia teaching database, online microteaching unit database, online data presentation mode database, online teaching and learning strategy database), data presentation mode database and teaching and learning strategy database. It can also be divided into five levels: core layer, platform layer, real database layer (multimedia teaching database, microteaching unit database), virtual database layer (data presentation mode database, teaching and learning strategy database) and environment database. So? Integrable ware? Resources is a large system. Teachers and students can call their own materials from its material library at any time, and then combine them through an easy-to-operate working platform. They can also add and improve the material library at any time. Integrable ware resources only seek to solve problems, unlike courseware resources, which need to do a good lesson. Integrable ware resources leave enough space for teachers to play a leading role in the classroom and give full play to teachers' aptitude. For example, as far as islands are concerned, there are colorful seawater, fish schools, squirming sea cucumbers, armored lobsters and beautiful corals playing under the seabed; All kinds of beautiful shells and huge turtles on the beach; All kinds of seabirds in the jungle are full of eggs and so on. Anyway, all the materials you can imagine are in it. Teachers can call exercises in the teaching unit library or call online information through networking. In this way, teachers can make use of information at will, making it change with invariability (integrable ware) (teaching practice). If such integrable ware is produced, it will definitely play a positive role in computer-aided teaching. This integrable ware unit is based on solving a problem, not the whole class or chapter. In this way, not only different schools, but also different teachers can use a common system, and this unit can also explain many problems. For example, this unit (pictures, animation, TV) can not only talk about the artistic conception of prose, ancient poetry or composition in Chinese class, but also talk about the change and fall of state in physics class, and also talk about climate-related knowledge in biology class and geography class. This is conducive to improving the versatility of integrable ware, improving efficiency and reducing costs.
Second, the relationship between educational technology resources
Educational technology resources are composed of hardware resources, software resources and software resources, all of which are learning resources.

Hardware resources and software resources are interdependent, based on the existence of each other. In education and teaching practice, hardware resources and software resources are usually used together. Excellent software resources are presented to students scientifically, clearly and perfectly through high-quality hardware resources, correct operation and suitable environment. Both hardware resources and software resources have physical forms, while potential resources are abstract and ideological things. In the process of accelerating the modernization of education, we must intensify the construction of hardware, software and submarines, the most important of which is the construction of submarine resources, so that the construction of submarine resources has a set of theories, a system and a system, and the construction of submarine resources should be horizontal, normal and systematic. In the relationship between submarine resources and software resources, submarine resources are the main aspect of the dominant contradiction. It is necessary to improve the submarine quality of teachers and students, cultivate teachers' awareness of audio-visual education, theory and practice, and guide students to master the correct learning methods.
Courseware resources and integrable ware resources belong to software systems. Courseware resource is a closed software system, and its personalized characteristics limit its application. Its form and content are completely fixed by the courseware designer. It is not necessarily good for others to make a courseware with good effect for one's own use, because he can't figure out the intention of the producer. To extract useful parts from other people's courseware and assemble it into a new courseware, technical means are often insufficient, and teachers themselves cannot reorganize and transform it. The so-called teaching methods and means, no matter how excellent educational experts and high-level teachers design courseware, can only be applied to specific teaching situations and cannot adapt to the ever-changing teaching reality. Therefore, the universality of courseware resources is not strong, and industrialization is difficult. Integrable ware resource is a completely open software resource system. Teachers can combine and use multimedia teaching information resources for teaching according to their own teaching needs. Integrable ware resource is a new idea for the development of computer-aided teaching in Chinese schools. It changes the situation that the design, development and use of teaching software resources are separated from each other, and enables teachers to easily make CAI software resources suitable for teaching situations. Integrable ware resources are the second generation of teaching software resources after the first generation of teaching software resources courseware resources. It is not a simple superposition of teaching resource database and multimedia writing tools, but a combination of teaching information and teaching processing strategy database and teaching work platform used by teachers and students according to teaching needs. Are integrable ware library and integrable ware combination platform integrable ware resources? Wings? . The multimedia teaching resource library, microteaching unit library, online integrable ware resource library, data presentation mode library and teaching and learning strategy library in integrable ware library provide sufficient material sources for teachers and students to make teaching software resources by using the integrable ware combination platform. The flexible, easy-to-use, open and practical integrable ware combination platform is a powerful tool to give full play to the creativity and initiative of teachers and students.
Three. Concluding remarks
Accelerate the application research of educational technology in teaching and really play an important role in teaching. The main content of its work is described in the definition of educational technology in 1994:? Educational technology is the theory and practice of designing, developing, applying, managing and evaluating related processes and resources in order to promote learning? . Therefore, the rich practice of educational technology and the contradictory movement within resources are the driving force for the development of educational technology, which is conducive to the rational utilization of educational resources, avoiding the waste of existing educational resources and promoting the overall level of educational technology. If our educational reform is guided by advanced educational theory and armed with educational resources such as educational technology, we can successfully meet the challenge of the new technological revolution and meet the needs of modernization with China characteristics.
