First of all, the questions raised
(1) research background:
2 1 century, information technology with multimedia and network technology as the core is gradually changing people's life, work and study, and has become a creative tool to expand human capabilities. Nowadays, making full use of information technology has become the need of educational informatization development, curriculum reform and further development of schools.
1, the need of educational informatization development: The rapid development of information technology at present has had a huge impact on traditional educational concepts and teaching models, and also provided technical support for the realization of educational modernization. The popularization of information technology has realized office modernization, optimized classroom teaching and brought more practical auxiliary functions to the classroom.
2. The need of new curriculum reform: Since the new century, China's primary and secondary education has been carrying out educational reform with "curriculum reform" as the core. This curriculum reform has brought new challenges to teachers. Information technology has been widely used in auxiliary teaching, but there are some problems in application and effect: some teachers can't use information technology correctly and can't improve classroom teaching efficiency; There are also many teachers who use information technology and do not design content for the important and difficult points. So how to use modern teaching methods to create situations for students and provide rich teaching resources? How to effectively use information technology and classroom teaching to highlight the key and difficult points of teaching? This is a realistic problem that teachers in our school are facing, and it is also a realistic and urgent topic that we are trying to explore.
3. The need for further development of the school: Our school has introduced information technology into the classroom. Through early training, teachers have a preliminary understanding of information technology and information technology has been widely used. A group of teachers have the ability to independently develop and make courseware. Teachers in our school have conducted in-depth exploration and research from the perspective of "classroom teaching", summed up some methods to optimize classroom teaching through action and reflection, and summarized the promotion experience on the basis of in-depth study of "how to build an information-based and efficient classroom".
(2) Guarantee conditions
The school has made outstanding achievements in information construction, vigorously promoted and strengthened information construction, built a campus network platform, and realized the class-to-class communication project. In order to provide necessary educational materials for teachers' education and teaching, our school has built an information resource library, including comprehensive materials such as courseware, music, videos and pictures, as well as live video of classroom teaching, which is convenient for teachers to make courseware and discuss education and teaching. With the continuous improvement of educational technology and equipment in our school, our educational technology and equipment are being built according to the national first-class standards. At present, our school has passed the acceptance of modern schools.
(3) Purpose and significance:
This paper studies the application of information technology to improve the effectiveness of classroom teaching, build a bridge between the abstraction of knowledge and the visualization of students' thinking, create situations, optimize classroom structure, highlight teaching difficulties, reform traditional teaching methods and means, and significantly improve teaching efficiency. It can not only create a unique and broad learning environment for students' learning, but also provide students with sufficient opportunities for observation, thinking and practice, which has unparalleled advantages in improving students' innovative ability and practical ability.
(4) Definition of subject:
Informatization in this topic refers to the application of computer multimedia and network information technology to classroom teaching to improve the effectiveness of classroom teaching and adapt to the new requirements of education development in the information society. Teaching informatization is to make teaching means informationized and teaching methods modernized.
Efficient classroom refers to normal classroom teaching activities, through the guidance of teachers and the active thinking process of all students, the teaching tasks are completed efficiently and with high quality in unit time, and the students' efficient development is promoted.
(v) Research objectives
Through the research of this topic, we strive to make students full of interest, explore independently and cultivate their thinking in the novel multimedia computer-aided teaching classroom, so as to realize all-round development and adapt to the requirements of the development of the new era for talents.
Objective 1: According to the characteristics of various disciplines, information technology is used to create situations for students to explore and discover in these situations, thus enhancing their interest in learning and enriching teaching resources.
Goal 2: Accurately analyze the combination of teaching content and information technology, and use information technology to highlight key points, break through difficulties and effectively improve classroom teaching efficiency.
Second, the research process
(1) research methods:
1, survey method: (1) survey the current situation of teachers using information technology in classroom teaching in our school; (2) Investigate the level and teaching effect of teachers' use of information technology in the research process, collect information and understand the situation.
2. Literature method: summarize, analyze and refine the theoretical research and practical experience of information technology and classroom teaching at home and abroad, and form the theory and method of classroom teaching under the information technology environment.
3. Action research method: research aimed at solving practical problems is to creatively apply theory to solve practical problems, practice under natural conditions, and constantly reflect on practice through four steps: planning, practice, observation and reflection.
(2) Research contents:
Focusing on the research objectives, the following contents are studied:
1. Use information technology to create students' learning situations and enrich learning resources. According to students' psychological characteristics, information technology is used to create teaching situations, and rich learning resources are integrated into the classroom to stimulate students' emotional excitement, so that students can experience the formation of knowledge in modern situations, make knowledge rise from perceptual knowledge to rational knowledge, and ignite the spark of students' wisdom while forming skills.
2. According to the teaching emphases and difficulties of a class, dig the teaching materials in a targeted way. In order to realize the cognitive goal in classroom teaching, it is necessary to solve the standard problems of "highlighting the key points" and "breaking through the difficulties". In traditional teaching, there are many ways to solve these two problems, such as language narration, wall chart display, hands-on operation, blackboard writing analysis, and combination of lecture and practice. However, when information technology is organically combined with it, it will make conventional classroom teaching like a duck to water. The application of information technology has advantages in highlighting key points and breaking through difficulties that other means cannot achieve. Instruct teachers to dig deep into teaching materials, analyze teaching difficulties, design information technology content, guide students to analyze, compare and synthesize the presented content from multiple angles and directions, and constantly complete "assimilation" and "adaptation" to build a new cognitive structure.
(3) Research process:
The idea of this study is to actively carry out the research on how to build an information-based and efficient classroom through planning, investigation, practice, summary and reflection, and by using the methods of investigation, action research and case study, and get the general laws and methods with popularization value. Starting with creating classroom lead-in situations and breaking through new teaching links, we should reform the traditional classroom teaching mode, solve the contradiction between subject and object, means and purpose, presupposition and generation, and strive to give full play to the advantages of information technology, improve classroom efficiency and improve teaching quality.
Third, the existing problems
In primary school mathematics classroom teaching, there will be students with similar learning foundations, the same textbooks, different teachers and different teaching environments, and the teaching effect is obviously different. What is the reason? How to solve it? With these problems, in recent years, the application of information technology to improve the effectiveness of classroom teaching in primary schools has been studied, mainly in the following aspects:
1, lack of analysis and evaluation in the choice of information resources.
Abundant online resources can bring convenience to the teaching and learning of teachers and students in the information age, which will be counterproductive if used improperly. In some interviews and teaching observation activities, it is found that some teachers download courseware from the internet when using information resources, and copy them completely in class. Teachers choose information resources at will, and there is no secondary organization or development. For example, in a teaching observation, the whole class is for students to watch the demonstration class, so classroom activities ignore the interaction between teachers and students and the guiding role of teachers, and lack the necessary emotional communication between teachers and students and the influence of teachers' personality charm.
2. Using information resources, one-sidedly emphasizing students' dominant position.
After learning the new educational theory, some teachers unilaterally think that classroom teaching should be "student-centered", and unilaterally implement this concept in actual classroom teaching, turning the classroom with the subject returning into a resource-based classroom with the theme of laissez-faire, excessively weakening the role of teachers, failing to combine the actual teaching situation well, and failing to realize that teachers should comprehensively use various information resources under the premise of taking students as the main body, and give full play to the leading role of teachers in guiding, enlightening and monitoring the teaching process.
3. The use of information resources ignores the realization of teaching objectives.
The application of information-based teaching resources in classroom teaching is to improve the effectiveness of classroom teaching and better achieve teaching objectives. However, in the actual classroom teaching, regardless of whether the information-based teaching resources are related to the teaching objectives of this class, the teaching activities are designed around the information-based teaching resources, not around the teaching objectives and teaching contents, so it is difficult to implement the teaching focus and break through the teaching difficulties.
Research achievements of verbs (abbreviation of verb)
Through research, the teaching quality, teachers' quality and students' creative quality have been comprehensively improved, and innovative education has penetrated into all aspects of school work. Mainly reflected in:
1. In the information technology environment, students are full of interest in classroom learning.
Classroom is no longer synonymous with boredom. Entering the innovation classroom means that there are countless surprises and explorations today. Teacher-student interaction, life interaction, stimulate the spark of creation. Teachers let students study freely and open the classroom to the maximum extent. It has become the mainstream of school classroom teaching to let students discover, explore and innovate by themselves.
In several surveys conducted by the county education authorities in our school this semester, the excellent and good rate of random lectures exceeded 90%. Twice reached 100%. In the national class teaching demonstration activities, leaders and experts all affirmed the level of using multimedia to create classroom situations and design innovative teaching.
2. Teachers have updated their teaching concepts, improved their teaching ability and enhanced their awareness of scientific research.
In order to ensure the smooth progress of the project and improve the ability of the participants, the research group has stipulated a monthly project meeting system. In the regular meeting, or study new problems in the implementation of the project, or summarize and check the work in the previous stage, or summarize the reflection after class, or prompt the matters needing attention in the next stage of research work. Through research, a strong scientific research atmosphere and a good scientific research environment have been formed, and a number of key scientific research teachers have been trained.
Our * * * teacher has published nearly 80 papers at or above the national level and won more than 60 awards. Our teacher Mao Yuanqun won the second prize in the State Mathematics Excellent Course Competition, and his thesis "Experience of Teaching Students in Accordance with Their aptitude" and case "Business in Classroom" won the second prize in the third national academic works selection activity of contemporary basic education.
3. Students' innovative consciousness, innovative spirit and innovative ability are cultivated and initially formed among all students.
Since the project started, students have been the biggest beneficiaries. In the new classroom where teachers change their ideas and improve their teaching level, they have their own time and space, and they get real respect and equal communication. In the new course of information technology, which focuses on students' autonomous learning, students participate in the whole process, use various senses and participate in teaching activities with interest. Stay at your best for 40 minutes and take part in the class's inquiry activities. Through your own efforts, you can really gain knowledge, cultivate your ability, develop your intelligence, learn to innovate, and learn to correctly handle all kinds of interpersonal relationships.
Experts and leaders who came to the school for investigation were amazed at the students' keen thinking, unique perspective, brave questions and bold performance in class. Students actively participate in all the affairs of the classroom and the school, boldly innovate and become "masters" in the true sense.
