New Curriculum Creating Problem Situations In The Teaching Of High School Solid Geometry

Mathematics curriculum standard special focus prominent students main Position in Training students participation awareness emotional experience, explore discovery and innovation. This context senior middle school mathematics solid geometry as students space imagination ability, logical reasoning ability, apply graphic language communicate ability and geometric intuitive capacity carrier is crucial. How create better problem situation in Solid Geometry Teaching, propose Solid Geometry Teaching Creation Question Situation effective strategies and methods enhance effective Solid Geometry teaching effects, concern.In this paper, theoretical and empirical research method of combining. In order to reveal the mathematics teaching problem situation created by the theory, use of literature study, with modern teaching theory, educational psychology, instructional design principles as its basis for analysis and demonstration and theoretical generalization; order to study the class of problem situation created by the teaching effect In theoretical analysis, based on an empirical study. Thesis is divided into five parts:The first part is the question. First of all, solid geometry knowledge in senior middle school mathematics is important position and analyzes the current situation of the students three-dimensional geometric knowledge, and then proposed the better creation of problem situations in three-dimensional geometry teaching is necessary and importance, and describes the research of this problem value and significance.The second part is mainly theoretical research. The production process from the problem situation and characteristics of teaching theoretical support for creating problem situations, new curriculum and teaching requirements under the three-dimensional geometric characteristics of the preparation of our new mathematics textbook situational characteristics of two required courses in senior middle school mathematics, "the preliminary three-dimensional geometry," a chapter problem situation and the preparation of statistical analysis of the characteristics of high school students in six areas of mathematics learning, to be discussed, shows three-dimensional geometry in senior middle school mathematics teaching in the feasibility of the creation of problem situations. ?The third part is problem situation created by the status of the investigation in the current three-dimensional geometry teaching, the purpose is to see problematic situation created by the phenomenon and how creation,what is the actual three-dimensional geometry teaching and why this creation and so on, proposing scientific and rational strategies and methods of foundation in the three-dimensional geometry teaching.The fourth part is problem situation created by the Strategies in the senior middle school math Solid Geometry Teaching. Based on previous theoretical analysis and status of the investigation, combined with my teaching practice, mainly from the eight aspects of the creation of the problem situation, to foster interest in the premise, induced initiative; to guide based on the observation enhanced sensitivity; to student activities for the channel, through the practice sex; to develop thinking, focus on creativity.The fifth part is the experimental study. Experimental results show that in the three-dimensional geometry mathematics teaching, through the creation of appropriate problem situation, improve the learning of mathematics enthusiasm and initiative, training and development of the students space imagination, logical reasoning ability and sense of innovation, optimize classroom teaching .
