First, the application of modern educational technology in middle school geography teaching
Middle school geography is a comprehensive course that integrates astronomy, meteorology, geology and geomorphology, soil vegetation, products, nationalities, industry, agriculture, transportation, commerce, tourism and other knowledge. It has the characteristics of diversity in form and extensiveness in content, infinity in time and space, and correlation among knowledge elements. Teachers should explain these geographical things and phenomena clearly and thoroughly within a limited time. It is difficult to rely on traditional routine teaching. Only by using models, specimens, charts, videos, televisions and other visual AIDS and modern teaching media can students' interest in learning geography be more effectively stimulated and teaching tasks be completed with high quality. Practice has proved that geography can overcome the obstacles of time and space by using modern scientific and technological means, which is conducive to the optimization of teaching process.
(A) the necessity of using modern science and technology education.
The rapid development of modern science and technology means that the contradiction between man and environment is becoming increasingly acute, and a series of important problems have appeared in the field of geography, such as: land division and rational utilization, rational allocation and diversification of grain production, protection and development of natural resources, protection and improvement of environment, destruction and reconstruction of ecological balance, etc. The development of modern geography inevitably requires the universal application of modern scientific and technological means. For example, the traditional time-consuming ground mapping and aerial photography must be replaced by new technologies such as satellite remote sensing, telemetry and remote control with high speed, high information density and strong timeliness.
(2) The infiltration of modern science and technology education principles in middle school geography teaching.
1. scientific principles.
Scientificality means that teachers teach students the basic knowledge and concepts of science with a scientific attitude, and improve students' ability to explore scientific problems through the process of scientific teaching. Geographical science is a part of modern science. According to the position and function of geography subject, combined with the scientific and technological knowledge of related content, students' ability to explore, explain and test problems is cultivated.
2. The principle of interest.
There are potential factors in students' interest in science and technology. As long as it is properly guided, this potential factor can be activated and students will have a strong interest in science and technology. For middle school students, we should pay more attention to guiding them to develop from perceptual interest to rational interest in time, so as to form real rational interest and have an impact on students' lifelong development.
3. Practical principles.
Practicality is mainly to cultivate students' ability to solve practical problems by scientific methods, which is the most effective way to improve students' scientific literacy. The practical activities of geography teaching include not only thinking processes such as observation, imagination, analogy and reasoning, but also operational techniques such as drawing, consulting maps, monitoring environmental factors and meteorological observation. A great deal of practical study plays a positive role in improving students' scientific literacy in an all-round way.
4. The principle of comprehensiveness.
Comprehensiveness refers to the infiltration of science and technology education in geography teaching, adhering to the position of comprehensiveness, development and connection, so that students can acquire more comprehensive scientific consciousness, knowledge, methods and skills from a holistic perspective and form a comprehensive scientific view. Geography itself is a comprehensive subject, and establishing students' correct scientific values is conducive to the integration of various factors in the teaching process.
Second, the improvement of modern educational technology in middle school geography teaching
It is a high-level pursuit of contemporary geography teaching reform to build a student's autonomous learning mode centered on multimedia teaching resources and computers and their networks, so that students can learn their own interesting content in a flexible form and relaxed atmosphere. The threshold effect of technology, the price effect of equipment and the concept effect of personnel have always been the restrictive factors in the modernization reform of geography teaching. From the practice of computer-aided geography teaching, we should strengthen it from the following two aspects:
(A) there must be sufficient education and teaching resources.
The integration of modern educational technology with subject teaching and courseware making is inseparable from the active participation and close cooperation of teachers. This requires teachers to fully understand the design principle of courseware, master the making technology of courseware skillfully, and create excellent auxiliary teaching software on the basis of extensive collection of materials and multiple-choice items. At present, in the development of teaching software, the combination of individual practice development and group business development is not close, and the horizontal communication between teachers is not smooth. What needs to be further strengthened in the future is that software companies should provide teachers with a variety of multimedia platforms with secondary development conditions, so that teachers can get the maximum development results with the least time investment and make the batch development and promotion of courseware more practical.
(2) Support and resource sharing.
In order to realize the integration of modern educational technology and subject teaching and achieve the best teaching effect, we must make good use of all kinds of hardware equipment and software resources scientifically and reasonably. Due to the imbalance of funds and equipment between regions and schools; Leaders at all levels have different understanding of the role of modern educational technology; The gap between teachers in the application level of modern educational technology; There is indeed the problem of rational allocation and full utilization of educational and teaching resources. Therefore, the new curriculum will pay full attention to the development and utilization of off-campus educational resources and information, form an open curriculum with close ties between schools, society and families, and expand the space for students to learn geography.
