A METHODOLOGY FOR CHARACTERIZING COMPUTER-BASED LEARNING ENVIRONMENTS

This paper presents a methodology for characterizing computer-based le arning environments, focusing on the cognitive, pedagogical, and inter active features. The framework for this characterization is explained in relation to the relevant theories and findings in cognitive and ins tructional research. The methodology is illustrated by a characterizat ion of computer-based learning environments developed by student teach ers and professionals. The usability of these environments is analyzed along the dimensions of the framework presented. The results showed t hat this methodology can systematically and precisely characterize the cognitive, pedagogical, and interactive features of computer-based le arning environments. It can be used to predict and explain the success or failure that a given software program promotes for learning partic ular types of knowledge. The applications of this methodology for the evaluation and design of computer-based learning environments, for ins tructional research in various instructional contexts, as well as for the study of expertise in the development of computer-based learning e nvironments, are discussed.
