PCMAT, an adaptive learning platform

This paper is about PCMAT, an adaptive learning platform for Mathematics in Basic Education schools. Based on a constructivist approach, PCMAT aims at verifying how techniques from adaptive hypermedia systems can improve e-learning based systems. To achieve this goal, PCMAT includes a Pedagogical Model that contains a set of adaptation rules that influence the student-platform interaction. PCMAT was subject to ...

Content adaptation for an adaptive hypermedia system

The aim of this paper is presenting the recommendation module of the Mathematics Collaborative Learning Platform (PCMAT). PCMAT is an Adaptive Educational Hypermedia System (AEHS), with a constructivist approach, which presents contents and activities adapted to the characteristics and learning style of students of mathematics in basic schools. The recommendation module is responsible for choosing different lea...

Intelligent recommendation system for e-learning platforms

As more and more digital resources are available, finding the appropriate document becomes harder. Thus, a new kind of tools, able to recommend the more appropriated resources according the user needs, becomes even more necessary. The current project implements an intelligent recommendation system for elearning platforms. The recommendations are based on one hand, the performance of the user during the training...

Learning objects recommendation in an adaptive educational hypermedia system

The aim of this paper is presenting the modules of the Adaptive Educational Hypermedia System PCMAT, responsible for the recommendation of learning objects. PCMAT is an online collaborative learning platform with a constructivist approach, which assesses the user’s knowledge and presents contents and activities adapted to the characteristics and learning style of students of mathematics in basic schools. The re...

A new species of Eufriesea Cockerell (Hymenoptera, Apidae, Euglossina) from nor...

A new species of Eufriesea Cockerell (Hymenoptera, Apidae) from northeastern Brazil. Eufriesea pyrrhopyga sp. nov. a short-tongued Eufriesea is described as a new species. It can be easily recognized for its predominantly violet lower frons and thorax, violet tergum 1 contrasting with the strong reddish coloration on the lateral portions of terga 2 to 4 and on entire terga 5 and 6, and head pubescence with cont...

Influência das condições de resfriamento sobre as propriedades superficiais e e...

Surface and electrochemical properties of the dimensionally stable anode Ti/(Ru0.3Ti0.7)O2 were studied as a function of the annealing temperature using different conditions in order to perform the cooling process of the oxide films (conventional thermal shock and the slow cooling processes). It was found that surface and electrochemical properties for the oxygen evolution reaction are both affected through the...

A experiência de reforma do Estado da Administração Popular de Porto Alegre do início dos anos 90 é analisada neste trabalho como uma alternativa às iniciativas inspiradas na agenda neoliberal. Em contraste com o insulamento burocrático daquelas, seu resultado foi a criação de um Estado inserido em relação à sociedade civil, aqui descrito como embedded autonomy. Depois de serem esclarecidos alguns conceitos do ...
