A Research On Developing Plausible Reasoning Ability Of Middle School Students

Plausible reasoning is a kind of reasonable and genuinely sound reasoning. The mathematical development of students contribute to the promotion of plausible reasoning ability of students to a profound understanding of math and train the students to seize life and the ability to practice the spirit of exploration and innovation, change rigid way of learning, and promote the rational construction of mathematical knowledge.Students plausible reasoning process: through observation or experiment to find summarized points, or analog; and proceeded to put forward conjecture; then test the correctness of conjecture; Finally, the suspect to prove or falsification, if speculation was falsification, the need to re - observation or experiments, the new one logical plausible process. Reasoning found that the ability of structure from analog into points, or of the ability to speculate on the ability to verify the ability of speculation. Reasoning students affected by many factors, such as student knowledge characterization, or the presentation of such tasks. Generally speaking, students characterized the reasonable knowledge, the more flexible and sensible reasoning for the smooth progress with the help of the greater Moreover, whether students have a certain method and restructuring strategy or the problems faced by the mission has also affected the sensible reasoning carried out.Although the nature of plausible reasoning exists in daily life, but it was often ignored in Mathematics Teaching, therefore, logical reasoning of students teaching is necessary. This study was on the eighth-grade class of about two hundred people in a "reasonable inference to strengthen the teaching helps students improve the fairness and reasoning ability," Experimental study found a definite conclusion. Change the concept of teaching, so that students experience Mathematical Reasoning that the real process of law through the nodes and links variant teaching students knowledge to promote reasonable and flexible characterization, improving student cognitive structure to students with the necessary intelligence methods and reasoning skills, and can in the face of problems or tasks accurate characterization; Focus on deductive reasoning and logical reasoning complementary; use of a self-example and the way to lead students to self-monitoring and self-reflection, and raise their meta-cognitive ability is to train middle school students the key to plausible reasoning ability.
