Several Trapped High School Mathematical Problem Representation Of Case Studies

With the deepening of the high school mathematics learning, more and more students in mathematics learning disabilities is becoming more and more big. In order to logarithmic trapped of mathematics study put forward some targeted Suggestions,the author decided by studying several trapped raw mathematical problem representation to find their weaknesses, characterization and suit the remedy to the case. As a case study is more concrete, more reaction on the details of a few small problem, so the author selected the five concrete number stuck living subjects, from the case, to find themselves trapped from common characterization of obstacles. In order to compare, and select 5 concrete number eugenics subjects, study together with the other five concrete number trapped raw.After a lot of literatures have deep thinking, the author decided to adopt oral report method from the general form of problem solving, statements in each stage of problem solving and time, the elements of problem representation terms, problem solving, knowledge structure, the effectiveness of problem representation and answer scoring six representation dimension logarithmic eugenics and trapped born of problem representation were compared. The six representation dimension can not only be exact in oral report material, also reflect the differences of different students in mathematical problem representation.Again to 10 participants carry on analysis, found several trapped birth there are mainly six vulnerabilities in mathematical representation.First, the number of trapped raw prone to inertia in the mathematical problems representation, namely in the process of problem solving, can only be associated with the most recent relevant knowledge, and won’t need it that combined with concrete problems to concrete analysis the type of knowledge.Second, the number of trapped too lack of mathematical problem solving method,combination with the characteristics of different topics that do not know to find the most appropriate method to solve problems.Third, several trapped in mathematics concerns too single, which often appear when they consider mathematics problem focus too much on a bit and ignore otherpoints need to pay attention to, so lead to errors.Fourth, the number of trapped the imperfection of the mathematics knowledge structure, namely mathematical knowledge in their mind is segmented, rather than the interrelated, so it can affect not only the knowledge migration, but also affect the mathematics theory knowledge of memory.Fifth, several trapped mathematical thinking is not clear, that they without a common thread in the process of problem solving thinking, prone to multiple branches, so that cause confusion and do not know how to start.Sixth, several trapped the continuity of thinking is not enough, in the problem solving often appear when a small section of the brain empty state, without the quick thinking of ideas for connection.
