Esta palestra considera o crescimento cognitivo de demonstrações em indivíduos e sugere que este crescimento ocorre em três mundos distintos de construção mental, e em cada mundo há uma concepção diferente para provas. O primeiro mundo está relacionado com nossas percepções e coisas são verdadeiras porque são vistas como sendo verdadeiras. Este mundo conceitualmente corporal pode se desenvolver através de crescente sofisticação para levar à necessidade de provas verbais para descrever geometrias euclideanas ou estruturas mais avançadas. O segundo mundo surge de nossas ações: contagem, mensuração, cálculos e provas ocorrem através da operação e manipulação de símbolos que evocam tanto processos quanto conceitos: o que eu chamo de mundo simbólico- proceitoal. O terceiro mundo, axiomático-formal, é um mundo de propriedades que são formuladas como axiomas e definições onde prova é feita por meio de deduções formais.

However, the main purpose of the visit was to attend the Doctoral Examination of Victor Giraldo:

Nelson Maculan, the Brazilian Secretary of State for Higher Education, is Chairman of Victor’s PhD Examination Committee.

Victor presents his thesis to the Committee and a room full of academics.

He is pleased to quote Henri Poincaré to illustrate his argument.
