The Researches Of The Teaching Of Word Problems On The Application Of Quadratic Equations Based On The Cognition Of Situations

Application of equation that is junior high school junior secondary mathematics teaching as a focus of the content of the formation of its students to develop equations of mathematical thinking and awareness has an important role. However, this part of the teaching, but the lack of clear theoretical guidance, teachers, topics, students training title is the most common teaching methods. This teaching is very inefficient but high-consumption, a large number of students are very afraid of this part of the study, teachers and even the level of skepticism. Therefore, this paper attempts an analysis of theoretical and practical research, to find a more effective application of the equation of teaching title.In this paper, a brief analysis of the human understanding of the history of equations to find the equation and the continuous development of knowledge and have a sound track, students learn by analogy found knowledge law equation. A brief analysis of the scenarios the main point of view of cognitive theory and content, and cognitive theory to scenarios as a guide, inspect the application at home and abroad question the teaching of the equation of the research on the value of these studies analyzed and deficiencies. Application of a dollar raised questions the overall idea of teaching: the application level according to the abstract classification of title, one dollar in all stages of teaching, combined with the actual care arrangements for students in the application of different levels as the teachers and students to study questions of the material, to create similar the real scenario of teaching mathematics to explore all the side issues and at different levels, and gradually understand the meaning of equations and solution of going through the process of problem-solving, the development of problem-solving capabilities. Discussed in detail the concept of promoting the formation of one dollar, one dollar to promote solution abstract problem-solving skills and promote the development of the design of teaching scenarios.Finally, through the teaching practice and case studies, the design of the above teaching to reflect on the strengths and weaknesses and found that the advantage of relatively high participation of students, teachers, teaching more flexible and open, the demerit is that the more difficult ones to manage the classroom, teachers are more high.
