“…Lessons learned in the experiment described here are useful for the design of interactions with the deaf involving knowledge communication supported by qualitative models. As part of these efforts, a similar experiment is being prepared to explore a qualitative model of the Daniell cell, developed to enhance the understanding of electrochemistry in secondary schools (Salles et al 2004). …”

Brazilian educational system is faced with the task of promoting deaf people educational rights. Presently, the deaf are integrated in the classroom along with hearing students. Qualitative Reasoning may provide tools to support Portuguese acquisition in the context of the development of scientific concepts. This study describes an experiment with eight deaf students being exposed to three articulate qualitative models organized in gradual levels of complexity. Questionnaires were used to assess ther students' ability of expressing ideas in written Portuguese using the ontology provided by the models. An interesting result was that five students were consistent in the ability of recognizing objects and processes, build up causal chains and apply them to a given situation, assessing derivative values of quantities and making predictions about the consequences of changes, and write up a composition about an ecological accident, using linguistic descriptions of the relevant physical and social processes. These preliminary results are encouraging and ongoing work is the development of models and textual material in different domains, such as electrochemistry, to explore the potential of qualitative models in second language acquisition.

“…Com essa base de causalidade, modelos qualitativos permitem tanto explicar o funcionamento como prever o comportamento do sistema, dadas as condições iniciais das simulações. Essas características favorecem aplicações em atividades educacionais, a partir das quais se pode estimular o desenvolvimento de raciocínio hipotético-dedutivo e da criatividade do usuário (SALLES et al, 2004;ALVES, 2015).…”

O presente trabalho apresenta resultados preliminares de uma pesquisa que busca investigar a efetividade de materiais didáticos fundamentados em técnicas desenvolvidas em Raciocínio Qualitativo (RQ), área da Inteligência Artificial que utiliza o raciocínio simbólico para representar funções matemáticas sem o uso de números e com relações de causalidade explicitamente modeladas. Estudos anteriores demonstram o potencial do RQ para abordar sistemas dinâmicos por meio de atividades que exploram, com o apoio de modelos de simulação, o uso de raciocínio hipotético -dedutivo para analisar conceitos complexos, e ampliam o leque de materiais e atividades disponíveis para os professores. Para tanto, construímos, na plataforma de modelagem DynaLearn (www.dynalearn.eu), um modelo qualitativo de simulação para ser usado no ensino de Ciências. Esse software é dotado de uma interface gráfica, que facilita a construção de modelos e a apresentação dos resultados de simulações. Neste trabalho descrevemos o processo de construção de um modelo qualitativo que tem o objetivo de promover a compreensão de conceitos sobre o efeito das chuvas no comportamento de uma cidade, em relação ao consumo de água potável. O modelo representa relações causais entre variáveis climáticas, vazão dos rios, o tratamento da água e o abastecimento urbano. Além de ter potencial para a utilização por estudantes ouvintes em aulas de Ciências, o modelo também pode ser empregado na educação de surdos, devido à maneira como explora os recursos visuais. PALAVRAS-CHAVE: Material de Ensino. Raciocínio Qualitativo. Ensino de Ciências.

“…VISIGARP is currently in use by researchers in various domains to test and communicate simulation results of their models (Nuttle et al 2004;Neumann and Bredeweg 2004;Tullos et al 2004;Salles and Bredeweg 2006), and by several teachers of academic courses which incorporate qualitative modelling in ecology, physics and chemistry (Salles and Bredeweg 2003a;Alvarez-Bravo et al 2004;Salles et al 2004). This proves that there is a need for a tool like VISIGARP to communicate knowledge about system behaviour, and that VISIGARP can be used by people from various backgrounds in different academic settings.…”

This article presents the design and evaluation of a tool for inspecting conceptual models of system behaviour. The basis for this research is the GARP framework for qualitative simulation. This framework includes modelling primitives, such as entities, quantities and causal dependencies, which are combined into model fragments and scenarios. Given a library of model fragments and a scenario describing an initial situation, the qualitative simulation engine generates predictions in the form of a state-transition graph. This rich knowledge representation has potential for educational purposes. However, communicating the contents of simulation models effectively to learners is not trivial. The predicate logic format used by GARP is not easy for non-experts to understand, and a simulation often contains so much information that it is difficult to get an overview while still having access to detailed information. To address these problems, a tool has been developed that generates graphical representations of the information contained in a qualitative simulation. This tool, named VISIGARP, incorporates a vocabulary of graphical elements for model ingredients and relationships, and combines these into interactive diagrams. VISIGARP has been evaluated by thirty students, with promising results, using a setup which included simulation results and exercises about Brazilian Cerrado ecology.
