Titre / Title: HOW TO LEARN COMPUTING CONCEPTS USING PREVIOUS KNOWLEDGE AND Knowledge Acquisition PROCESSES
Abstract : Most practical researches about knowledge acquisition have showed that subjects make use of their previous knowledge in understanding processes. Several of these researches even set off the significance of previous knowledge in any understanding process, but they do not include any explanatory device about the incorporation of new information into previous knowledge. Some researches have described that a new information is either compartmentalized or incorporated with the subject's previous knowledge. A compartmentalized information is isolated from the corpus of the subject's previous knowledge, forming a new knowledge corpus. This kind of knowledge is activated only when the context containing the information learned is activated too. An incorporated information is associated with the subject's corpus of previous knowledge and allows the access to a great variety of situations that are distinct from the ones where the information was learned. The aim of this paper is to describe two practical experiments made with experts and novices in computer science. The main goal of these experiments is to investigate the integration of new information with previous knowledge. In the first experiment, subjects learned a set of computing concepts and then they were tested on paragraphs that required them to make an inference introducing the newly learned concepts in several contexts. In the second experiment, the same test statements were proposed, but the concepts learned were replaced by a part of their definitions. These experiments suggest that previous knowledge facilitates the incorporation of new information by experts and that the lack of old knowledge in the domain induces novices to compartment new information.
