The Investigation Of Teaching Logic Knowledge In Secondary School

In modern mathematics, the language of mathematical logic has become the common language of expression in mathematics. The exercise of its semantics, syntax, and meaning has become the important component of the basic mathematics attainment. And also increasingly being the important part of secondary mathematics teaching. Moreover, the knowledge of logic has infiltrated the mathematical part of the materials, and being a very important role in students thinking ability level.In one hand, this paper studies over the years of the curriculum and teaching mathematics in logic content changes, and found that as a result of the conflict of the needs to students' knowledge logic and level of understanding of students mathematics and teachers' knowledge reserves of logic, their right to knowledge and logic demand is bumpy. The other hand, through surveys and interviews to understand the teachers and students' problem in teaching logic knowledge, including many teachers had not been systematically studied logic of knowledge, students easily confused of mathematics knowledge and logic with their intuition, experience and knowledge of life, and so on.Finally, we address these issues raised some of the materials and methods improved, including an early start to infiltrate the symbols of expression in the form of teaching logic and strengthening the combination of concrete examples and form logic, and proposed adding material on the simple proposition with composite proposition, contains link words and the truth table, etc., hoping to help teachers carrying on teaching logical knowledge.
