Investigation On The Concept Of Conic Curve And The Learning Situation Of Related Content

Conic curve is not only the core content analytic geometry in high school, but also the whole basis of analytic geometry. High school textbooks after several changes, but each change, conic curve is one of the key contents of senior high school. One of the key contents of learning concept of conic learning is the senior high school students. Comprehensive knowledge of high school algebra, using the geometric process in concept learning of conic curve and related content in the. The basis of learning the content and thinking method is also concerned with analytic geometry. At the same time the conic curve is widely used in real life, such as the movement of celestial objects, military, navigation and other aspects plays a very important role.The APOS theory and concept learning theory as the theoretical foundation, through the literature analysis and questionnaire survey, from the concept of student learning process, understand science students of senior two and the relative content of conic curve concept learning. Mainly study the following three questions:(1) science students of senior new curriculum requirements for conic curve concept and related content to learn how?(2) what are the main problems in science students of senior conic in the learning process?(3) through investigation and Research on students’ learning and teachers’ teaching what enlightenment. This paper focuses on the problem(1) and the problem(2).Through investigation and test results of the questionnaire statistical analysis found that science students of senior two in some conic concepts and relevant contents are the following three main problems:(1) high school science students on the definition of conic variable and invariant and the relationship between their understanding is not deep enough;(2) science students of senior two in the definition of conic form transformation and difficult;(3) the science students of senior two in the conic curve concept is put in the practical problems combined with an understanding more difficult.By the questionnaire test results are obtained heuristic teacher in conic curve concept teaching pay attention to the following three aspects of teaching:(1) the concrete content of conic curve concept, strengthening and invariants, and their relationship analysis, guiding students to improve the transformation ability;(2) will the conic curve concept teaching put in actual living background.(3) to reveal the generation and development of knowledge, so that students learn the history of the development of conic curve.
