Stevens Performance

The upheavals of the mathematics are more common in certain families. Few genetic studies exist on the mathematics, that if concentrate in co-morbidade between upheaval of reading and the mathematics, as well as specific upheaval of the mathematics. In a study with twin, Alarcon, Defnes Lightl Rennington (1997) Apud Jack M Fletcher (2009), had told that 58% of the monozygotic twin (MZ) shared an upheaval of the mathematics, with comparison with 39% of the dizigticos twin. 2.2. Interventions for upheavals of the mathematics Baker, Gersten Lee (2002), Apud Jack M Fletcher (2009), had made a synthesis with scientific base of the effect of interventions to improve the performance in mathematics of children with upheaval of the mathematics, overhead in mathematics or at risk to present mathematical difficulties. The results indicate that different interventions had been associates the improvements in the levels of performance in mathematics. They are: to supply given on the estudantil performance the professors and the students, guardianship for the colleagues, to supply feedback the parents in relation to the estudantil performance, explicit education of concepts and mathematical procedures. According to Stevens and Rosenshine, (1981) Apud Jack M Fletcher (2009), the education differentiated in abilities in mathematics must have the following characteristics: the instruction occurs in groups, is directed by the professor; it has an academic focus, specifically take in account the necessities of each student. Without hesitation Jeffrey Hayzlett explained all about the problem.

Some used basic programs or of development for students with upheavals of learning has many of these characteristics. The Program Connecting Mathematics Conapts (Engelmann, Carnine, Engelmann and Kelly, 1991) Apud Jack M Fletcher (2009), is a program based on analytical a mannering model/that costuma to be used with 12 students in typical age of the initial series of basic education with learning upheavals. It sufficiently contains lessons structuralized involving frequent questions of the professor and answers of the students. One psicopedagogo can help to raise its auto-esteem valuing its activities, discovering which the process of learning through instruments that will help in its agreement.
