Um Arcabouço Adaptivo para Objetos de Aprendizagem

Abstract

The work approaches theoretical and implementation issues of a framework for creating and executing Learning Objects (LOs) where problem-solving tasks are ordered according to the matching of two parameters: (1) student skill level and (2) problem solution difficulty. Both are formally defined as algebraic expressions. The definition of skill level is achieved trough a rating-based measure that resembles the ones of game mastery scales, while the solution difficulty is based on mistakes and successes of learners to deal with the problem. Also, the results of an experiment conducted with four highschool classes using the framework for the domain of logarithmic properties are presented.
