Elaboração e avaliação de uma hipermídia sobre cinética química com base no ensino por resolução de problemas

Abstract

In recent years, it has increased the number of publications related to teach-ing and learning based on problem solving, which is considered an important teach-ing strategy, as its distinctive character to the approach of school subjects. The artic-ulation of information and communication technologies (ICT) to the learning based on problem solving (PBL) becomes an interesting teaching strategy, since both aim to prepare the students to have the ability to act in decision-making as critical citizens aware, in addition to providing a better discussion of chemical concepts related to subjects that require students` abstraction and understanding of content considering the three levels of chemical knowledge. Thus, in order to contribute to this line of re-search, this paper proposes to construct and evaluate a hypermedia on chemical ki-netics as reference for teaching problem solving. Through internet and analysis of articles, obtained information about the chemical content present in hypermedia already published for the teaching of science and what the levels of chemistry knowledge presents in published materials for the chem-ical kinetics. After research and analysis of alternative conceptions presented by stu-dents about chemical kinetics, went defined the types of problems that would be in-corporated into hypermedia. Hypermedia was built using the graphical software vec-tor Adobe Flash Professional CS6. The evaluation of hypermedia was made by teachers and doctoral students connected to the research area of information and communication technologies in science education at the Federal Rural University of Pernambuco, through the application of an adapted and validated questionnaire in previous work. The result of the evaluation in the overall context was positive about the content, quality instructional and technical hypermedia, with reservations on some opposing viewpoints regarding the function of hypermedia in the reasoning stimulus and student creativity, given the fact that such stimulation is realized not the material itself, but by use of strategy that does the same.
