First, the concept and characteristics of modern educational technology
Educational technology is the theory and practice of designing, developing, utilizing, managing and evaluating learning process and learning resources. Modern educational technology is the theory and practice of using modern educational theory and modern information technology to realize teaching optimization through the design, development, utilization, evaluation and management of teaching process and teaching resources. Modern educational technology has the following characteristics: the focus and foothold is students' learning, which fully embodies students' dominant position. Therefore, its research object is learning process and learning resources; Its research content includes five aspects: the design, development, utilization, management and evaluation of "learning process" and "learning resources"; It embodies the dual attributes of theory and practice; Educational technology is the product of the combination of advanced educational thought and advanced teaching technology. With the development of modern science and technology and modern educational thought, modern educational technology constantly updates and enriches its own connotation.
Second, several misunderstandings in the application of modern educational technology
In China's social reform, the educational reform lags behind the economic reform, and in the educational development, the concept renewal lags behind the equipment renewal. It is the lag of educational concept that leads to the misunderstanding of the application of modern educational technology.
1. Subjectively mistake advanced educational technology for advanced teaching.
The process of teaching is the process of information transmission, which requires means. Modern educational technology provides various advanced means for information transmission. So some teachers think that advanced educational technology is advanced teaching. In order to reflect the advanced educational technology, some problems that should have been demonstrated by experiments have also been made into three-dimensional animations, and some even show every link of the class with multimedia courseware. On the surface, educational technology is advanced, but in fact it is just a "flower shelf". The teaching concept is traditional, and the teaching method is outdated. Just putting on a layer of advanced educational technology does not mean that teaching is advanced at all. It should be emphasized that the application of modern educational technology must be guided by advanced teaching concepts and adhere to the principles of heuristic, interactive and student-centered. If we deviate from this principle, no matter how advanced educational technology is, it will not achieve good teaching results.
2. I mistakenly think that multimedia teaching mode can replace all traditional teaching modes and ignore the leading role of teachers.
Multi-media teaching mode has developed the past single education and teaching mode into a multi-mode of interaction among students, teachers and media; Students' learning style has changed from passively accepting knowledge to actively learning knowledge through modern teaching media. However, as a teaching method, modern teaching media also has its own defects.
First of all, modern teaching media only play an auxiliary role in teaching and can only play the role of teaching service. It can't completely replace teachers' teaching activities in class. In classroom teaching, teachers should not only make students clear the teaching purpose, but also pay attention to adjusting students' learning attention and give timely feedback to correct it, which is also the embodiment of teachers' leading role. However, some teachers do not grasp their leading role and the auxiliary role of computer multimedia, which leads to putting the cart before the horse.
Secondly, the attraction of teachers' body language and emotional color to students can never be replaced by computers. However, the multimedia teaching model weakens the role of teachers' personality demonstration and changes the teaching classroom from "one person" dialogue to "one person, one machine" dialogue. Over time, there is a lack of emotional communication between teachers and students, and students are prone to develop unsociable and indifferent psychological characteristics.
3. Excessive use of multimedia courseware tends to ignore students' cognitive rules.
Some teachers use multimedia courseware in the whole teaching process, display all the teaching contents on the big screen and act as projectionists. The teaching effect is not good. In addition, when making courseware, we blindly pursue multimedia effects and use too much sound, pictures and animation to express teaching content. The result is self-defeating, but it distracts students' attention and deviates from the theme of knowledge transfer. Other teachers, regardless of the particularity of the subject and the knowledge they impart, all adopt multimedia teaching methods, ignoring students' cognitive rules, and showing the process of formula derivation and example calculus at one time, which neither leaves students time to think and digest, nor trains students' logical reasoning ability.
4. Modern educational technology only pays attention to information technology in teacher training and ignores modern educational theory.
For a long time, in order to meet the challenge of educational informatization, educational administrative departments at all levels and primary and secondary schools have strengthened the training of modern educational technology for teachers, which is very necessary to improve teachers' quality and promote educational informatization. However, some schools only take making courseware or web design as the main purpose of teacher training, ignoring the study and improvement of teachers' educational concepts, educational ideas and teaching designs. However, teachers only pay attention to the study of production skills in training, blindly pursue the exquisite form of courseware, and pay little attention to the study of modern educational theory and teaching philosophy. The reason for this phenomenon is the one-sided understanding of the concept of modern educational technology, which only attaches importance to information technology and ignores modern educational theory.
Third, the rational use of modern educational technology to achieve the best teaching results.
1. Fully understand the true connotation of modern educational technology and establish a new educational concept.
When it comes to modern educational technology, people think more about modern information technology such as multimedia and network, but ignore the modern educational theory in modern educational technology. In fact, modern information technology is only the resource and technical support of modern educational technology, and it cannot represent the whole of modern educational technology. It is one-sided and incomplete to think that modern educational technology is a technology that uses modern media to transmit teaching information.
At present, modern information technology with multimedia and network as the core is accelerating to enter schools, but these new technologies only provide a new educational resource and environment. New technology itself will not play a role in schools in isolation. Only under the guidance of modern advanced educational ideas and concepts, reflecting the spirit of the times of quality education and innovative education, can we play a positive role in promoting education and teaching. If the educational concept is outdated and the new technology is only applied to the traditional teaching mode, the new technology will not only fail to exert its advantages, but will become a means and tool to strengthen the traditional teaching mode and teaching concept. Therefore, this requires educators to get rid of the shackles of traditional educational concepts and establish new educational concepts. Only under the guidance of new educational ideas can we correctly apply new technologies, reform traditional educational models and improve teaching quality.
2. The rational use of modern educational technology, teachers should still be the main body to determine the teaching effect.
In classroom teaching, teachers are the organizers of teaching, and modern educational technology is only a means to assist teaching. Multimedia courseware can help teachers better express and elaborate the teaching content, but the leading role of teachers can never be replaced. Because the teaching design and content organization of courseware are completed by teachers, whether the construction and design of courseware conform to the learning and cognitive laws of students determines the teaching effect. At the same time, in the teaching process, teachers' language, movements, expressions, scientific spirit and cognitive habits all play a subtle role in promoting students' learning, which is an important information and motivation. At the same time, teachers effectively organize classes and guide students to think and observe problems, which is more conducive to stimulating students' enthusiasm for learning and knowledge exploration. This kind of tacit communication between teachers and students is also impossible for computers.
3. Absorb the advantages of traditional teaching methods, and the use of multimedia should conform to students' cognitive laws.
Although the traditional teaching method of "blackboard+chalk" is not intuitive enough, it has irreplaceable advantages in modern educational technology. Traditional teaching methods have two advantages: first, the process of teachers' writing leaves students with room for digestion and thinking; Second, the process of writing is a process in which teachers bring students into logical thinking. Therefore, teachers should pay attention to absorb these two advantages when designing and making courseware. How many words appear on the same screen should be strictly controlled, and the formula derivation process should be gradually displayed to give students enough time to think and digest.
Although multimedia teaching has many advantages, such as extensive teaching content, rich teaching resources, vivid teaching process and high teaching efficiency, we should not pursue multimedia effects excessively. The abuse of media materials and the excessive addition of animation effects will affect students' attention, make them unable to grasp the key points of knowledge and affect the teaching effect.
4. Strengthen teachers' modern educational technology training, strengthen modern educational teaching theory and update educational concepts.
The real application of modern educational technology in teaching practice must be completed through the teaching activities of front-line teachers. Teachers' understanding and application of modern educational technology is the key factor for modern educational technology to play its role. Training teachers in educational technology can promote them to carry out in-depth reforms in teaching concepts, teaching contents, curriculum system, teaching methods and teaching means, thus improving the quality of personnel training. What needs to be emphasized is that modern information technology must be mastered and used by teachers, and teachers' behavior is dominated and restricted by ideas. Concept is the forerunner of behavior and controls the direction of behavior. Practice under the guidance of wrong ideas is more terrible than blind practice. In this sense, it is more important to learn modern education and teaching theories and update educational concepts than to learn modern information technology.
In a word, the wide application of modern educational technology in teaching has brought new vitality to education and made teaching more vivid and efficient. We should get out of the misunderstanding in the application of modern educational technology, make good use of modern educational technology under the guidance of modern educational theory and teaching concept, give full play to its advantages, continuously improve teaching quality and truly modernize education.
