A presente pesquisa centra-se no estudo das relações entre memória de curto prazo, memória de trabalho, velocidade de processamento, processamento visuoespacial, funções executivas, atenção seletiva e alternada e desempenho matemático, uma vez que essas relações podem esclarecer as diferenças entre os alunos na aprendizagem da matemática. O trabalho teve como objeto de observação crianças da 2ª série do ensino fundamental. Consiste em um estudo com base correlacional e comparativa. A amostra desta pesquisa é composta por 40 alunos, com idade entre 8 e 9 anos. A investigação envolvendo o funcionamento neuropsicológico e o desempenho cognitivo na aprendizagem matemática é relevante, pois para desenvolver habilidades de cálculo matemático é fundamental que o aluno tenha construído o conceito de número e esta construção está vinculada ao desenvolvimento das funções neuropsicológicas. O desempenho matemático é avaliado através da Prova de Aritmética de Capovilla, Montiel e Capovilla (2007) e as funções neuropsicológicas, através de quatro subtestes da Escala Wechsler WISCIII, que são: Memória de Curto Prazo – teste de Dígitos de Ordem Direta; Memória de Trabalho – Dígitos de Ordem Inversa; Velocidade de Processamento - Procurar Símbolos e Códigos; Percepção Visuoespacial – teste de Cubos. A Função Executiva é avaliada através do Teste das Trilhas de Montiel e Capovilla (2007) e a Atenção, através do Teste de Atenção por Cancelamento de Montiel e Capovilla (2007). Observa-se uma correlação significativa entre Desempenho Matemático e Memória de Curto Prazo, Velocidade de Processamento, Função Executiva e Atenção. Neste estudo, não se encontrou uma correlação estatisticamente significativa entre as funções Memória de Trabalho e Processamento Visuoespacial. / This paper approaches the relationship amongst neuropsychological functions –Short Term Memory (STM), Working Memory (WM), Speed Processing (SP), Visual Spatial Perception (VSP), Executive Functions (EF), Attention (A) and Math Performance (MP) in 2nd grade children at a public Elementary School from Porto Alegre. It is a comparative and correlation study. The sample of this research is composed for 40 pupils with are between 8 and 9 years. Research involving neuropsychological functioning and cognitive performance in mathematics is pertinent, for it is essential that the student build the notion of number in order to develop mathematical skills and such construction relies on the expansion of neuropsychological functions. The mathematical performance is measured by the Arthmetic Test of Capovilla, Montiel and Capovilla (2007) and the neuropsychological functions are verified by subtests Wechsler WIS CIII; Short Term Memory is assessed by the Digits in Direct Order, while the Working Memory is established by the Digits in Reverse Order. The speed processing is assessed through the use of Find Symbols and Codes activities, and spatial perception is confirmed by the utilization of cubes. The Executive Function is assessed by the Trail Making of Montiel and Capovilla (2007) and attention is assessed by the Attention Test for Cancellation of Montiel and Capovilla (2007). There is a momentous correlation amid math performance and Short-Term Memory, speed processing, executive function and attention. This study one did not mett, however, the establishment of a statistically significant correlation between the Working Memory functions and the Visual Spatial Processing.

>Magister Scientiae - MSc / An analysis of South African school mathematics results indicates that one of the problem areas in the mathematical performance of learners is proof and proving. In an endeavour to improve the mathematical proving ability of first year students at UWC, the MAM 112 class (a first year elective mathematics course) was taught a course in elementary logic. In the initial part of the study, logic puzzles were utilized as a tool to teach students to make logical connections between and from mathematical statements using the rules of inference. Subsequently research was done to determine if knowledge and understanding of logic would translate into improved proving abilities of students. To put proof and proving into perspective the origins and functions of proof was explicated and proving in South African schools was investigated. Consequently reasons are advanced for the dismal high school mathematics results in terms of proof and possible solutions are discussed. Recent discoveries of neuroscience are utilized to delineate the brain structures and cognitive processes involved in learning so as to gain a better understanding of the learning of mathematics. The findings of neuroscience, cognitive psychology and educational psychology are employed to elucidate the influence of emotion, confidence, experience and practice on the learning of mathematics in order to determine which factors can be applied to improve the proving abilities of students. The findings of the study indicate that knowledge of logic does help to improve the ability of students to make logical connections (deductions) between and from statements. The results of the study, however, do not indicate that knowledge and understanding of logic translates into improved proving ability of mathematical statements by students.

This mixed methods research design, which was modelled on the constructivist view of schooling, sets out to investigate the effect of developing mathematical problem solving skills of grade 8 learners on their performance and achievement in mathematics. To develop the mathematical problem solving skills of the experimental group, a problem-centred teaching and learning environment was created in which problem posing and solving were the key didactic mathematical activity. The effect of the intervention programme on the experimental group was compared with the control group by assessing learners’ problem solving processes, mathematical problem solving skills, reasoning and cognitive processes, performance and achievement in mathematics. Data were obtained through questionnaires, a mathematical problem solving skills inventory, direct participant observation and questioning, semi-structured interviews, learner journals, mathematical tasks, written work, pre- and post- multiple-choice and word-problem tests. Data analysis was largely done through descriptive analysis and the findings assisted the researcher to make recommendations and suggest areas that could require possible further research. / Mathematics Education / M.

1 online resource (xii, 171 leaves) : illustrations (chiefly color), color graphs / ADHD negatively impacts academic performance, and the traditional classroom setting conflicts with the symptoms of ADHD. This research examined the potential of teaching through play and peer-teaching as alternative teaching methods to improve the mathematical performance of Grade 1 children with symptoms of ADHD; by answering, would adapting teaching methods to include teaching through play and/or peer-teaching, in the South African classroom, improve the mathematical performance of children with symptoms of ADHD? A pre-test-post-test control group design was employed in this comparative experimental study. Participants were purposively selected then randomly assigned to one of three intervention groups. An eight-week intervention was implemented as teaching through play or peer-teaching. Pre-test and post-test scores were analysed using a dependent t-test, a Wilcoxon Signed Rank test, and a Kruskal Wallis test. Teaching through play and peer-teaching have the potential to improve the mathematical performance of Grade 1 children with symptoms of ADHD. Special precautions were taken in the process of minor research participants, adhering to the ethical principles of beneficence and non-maleficence, justice, and autonomy. / Psychology / M. Sc.
