Teaching Experimental Study On Elective Course Of High School Math "Trisection Of An Angle And Expansion With Number Field"

1 Topics of the background and significance"Trisection of an angle and Expansion with number field"I developed high school division of school-based curriculum,"high school math elective courses on the topic"in a special topic, it will take into our secondary school curriculum content, the"ordinary high school mathematics curriculum standards,"the whole new arrangements. At present, when our country is an excellent basic education background. Author choice"Trisection of an angle and Expansion with number field"of the topic as research papers have the following meanings:(1) To allow students to understand and master the three ancient Greece geometric mapping;(2) For the mathematics curriculum reform, development and training of qualified teachers force;(3) Turn over to think about teaching experiment. Geometric Construction of the basic education in junior high school mathematics curriculum reform receive special attention, and it in the contemporary social life and training students hands-operation of the practice of mathematics accomplishment of the important role inseparable. This not only reflects the"three ancient Greek geometry Geometric Construction can not"Duishuo history, it has also embodied the"three sub-angle and the expansion of domain"Students comprehensive mathematical concepts (geometric algebra or algebra problem issues geometry) and the integrity of the mathematical literacy areas have the role. Accordingly, the topic of the teaching is of practical significance.2 Research MethodsPapers mainly uses the literature, research, teaching and experimental observation of these different methods.3 The main contents of papersThis paper is divided into three parts:(1)"Trisection of an angle and Expansion with number field"of the topic issues and knowledge systems;(2)"Trisection of an angle and Expansion with number field"of the teaching process; (3)"Trisection of an angle and Expansion with number field"in the concluding experimental teaching and reflection;At present the"three sub-angle and a few domain expansion,"Experimental Study on the topic rarely, in my high school mathematics curriculum development is the first try. The first appeared in the senior secondary curriculum, part of the contents of this reference rarely available. Fortunately, prepared by S C Lee High School Mathematics extra-curricular books on reference materials, other specific content of courses has now found no. Therefore, this part of the curriculum for teaching and research is necessary. Experimental study on the teaching of China's ongoing reform of high school mathematics curriculum and to a certain extent from the reference value.4 Studies have concludedBased on the topic of teaching and assessment, testing, surveys, interviews, etc., were studied in teaching high school teachers and students with the specific circumstances of the experiment and teaching results. Knowledge of the topic although theoretically require relatively high, but after a number of teaching and learning, the authors suggest that the content knowledge of the topic for the teachers and students of higher learning should be a big problem in the Teachers College of Mathematics and professional teaching Symposium-learning. Only through learning by promoting professional Mathematics Teachers College students specialized high growth, high school can deal with the implementation of new curriculum and the needs of high school mathematics teaching. The teaching experiment measured by the result of investigation results are not very satisfactory. Particularly the high school students after the test results polarization rather serious. However, the author think that the teaching process than teaching the test result more reference value in the future for the implementation of the general topic of high school teaching experience and provide some information, and contribute to the high teacher-student high school math teacher after teaching duties.
