The Research Of Teaching On Mathematics Problem Finding In Senior School Based Information Technology

In recent years, "problem posing" has become the core theme of mathematical education following "problem solving". To learn "problem finding" is beneficial to person's mathematical literacy, such as abstract mathematics, mathematical modeling, logical reasoning and the imagination. In the research project about the students'core ability of mathematics, "problem posing" is in the frame of evaluation. According to the 2015 revision of "Ordinary High School Mathematics Curriculum Standards", one of the major changes is that "the ability of finding and posing problem from the persp-ective of mathematics" was explicitly included in the curriculum objectives. Furthermore, in the field of teaching and learning,"problem finding" is regarded as an effective teaching device and learning method. Compared to problem solving, problem finding may be more challenging in mathematical learning process. And to some extent, the involvement of Information Technology(IT) makes finding process traceable, and improves students' cognitive processes of problem finding.The first part is the reason and rationale of the research. On this basis, we propose the research subject:The Research of Teaching on Mathematical Problem Finding in Senior School based Information Technology. The aim is to explore the law of problem finding in senior school mathematical classroom teaching, make the students form problem awareness and learn to find problem in a planned way by IT.The second part is the teaching research about how to improve students'cognitive processes of mathematics problem finding by use of information technology. First, we analysis students'cognitive processes of problem finding, and the role that IT and situation-setting play in students'problem finding process. Secondly, three situations suitable for using IT to assist with problem finding are selected (physical situation, operation situation, variant situation), then we discusses the tactics of using IT for inspiring students to find problem under the three situations. Finally, the models of mathematics problem finding processes are proposed.The third part is the practice of the research, to test the above theoretical research fruit in practical teaching, and it's verified to be correctness and feasibility.
