Adaptabilidade de Objetos de Aprendizagem usando Calibragem e Sequenciamento Adaptativo de Exercícios

Abstract

Resumo Este trabalho aborda questões teóricas e de implementação de um arcabouço para a construção e execução de 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, both calculated automatically: (1) student skill level and (2) problem solution difficulty. They are formally defined as algebraic expressions. The definition of skill level is achieved through 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. An empirical study based on existing students data demonstrated the suitability of the formulas.Besides, the motivational aspects of learning are considered in depth. In this sense, it is important to propose activities according to the student's level of expertise, which is achieved through presenting students with exercises that are compatible with the difficulty degree of their cognitive skills. Also, the results of an experiment conducted with four highschool classes using the framework for the domain of logarithmic properties are presented.

Conception of Learning Objects with Feedback for Self-Regulation of Learning Mathematical Concepts Necessary for Differential and Integral Calculus

“…In higher education, Kutzke and Direne (2018) studied the mediation of error in computer programming teaching, describing the proposal of a system framework for the manipulation of error records (FARMA-ALG) that promotes the mediation of the error with effective teacher participation. In turn, Silva et al (2018) present ADAPTFARMA, a modified version of FARMA, which consists of a sequence of exercises after an introduction, which is the theoretical part of an LO in which concepts are defined through text, images, audio, and videos. In the same vein as FARMA-ALG and ADAPTFARMA, the work intends, in a second phase, to adapt a version of FARMA that is specific for error remediation and self-regulation of the learning of DIC concepts, called FARMA-CALC.…”

Sequenciamento de Ações Pedagógicas baseadas na Taxonomia de Bloom usando Planejamento Automatizado apoiado por Algoritmo Genético

“…Em informática na educação, é comum observar a utilização de técnicas computacionais que promovem intervenções pedagógicas relacionadas ao ensino, à aprendizagem, ou ambos. Nesse sentido, o sequenciamento pedagógico pode ser utilizado com o objetivo de auxiliar no processo de aprendizagem (Silva, Direne, Marczal, Borille, & Guimarães, 2018), (Júnior, Araújo, & Dorça, 2020). Tais intervenções podem contar com técnicas de Inteligência Artificial (IA).…”
