Desenvolvimento e avaliação de um sistema informatizado de instrução para a formação de conceitos

Abstract

Programmed Education, Teaching Machines and the Personalized System of Instruction (PSI) are behavior-biased approachs to education which guided the design of a computer-aided educational software based in choice tasks used to evaluate two instructional conditions: choices among definitions and choices among examples, with naive and experienced students. Tasks were built considering performances as training of intraverbal operants relatated to concepts and allowed to verify the decrease in errors after first block of trials in all four conditions. Performances in all four conditions were similar, naive and experienced students equally benefited of the program. Data indicated transfer of learning to a post-test categorization task. Comparisons between complex questions with multiple choices between examples and definitions must be cautious. Errors concentrated in the first block of questions of each concept indicated that samplecomparison relations transferred to questions presented in the next block. Parametric manipulation in future studies may generate more evidences on variables contributing to better learning of concepts in computer programmed choice tasks.
