The purpose of this study was to examine the effects of visual representations and time-compressed instruction on learning and learners' perceptions of cognitive load. Time-compressed instruction refers to instruction that has been increased in speed without sacrificing quality. It was anticipated that learners would be able to gain a conceptual…

Faced with highly complex and ambiguous visual input, human observers must rely on prior knowledge and assumptions to efficiently determine the structure of their surroundings. One of these assumptions is the "light-from-above" prior. In the absence of explicit light-source information, the visual system assumes that the light-source is roughly…

Suggests that seeing is much more than a passive intake of images by the brain. It involves great mental activity and is dependent upon prior experiences. Cites a variety of authors from a variety of disciplines who have written about seeing. Contains 19 references. (DDR)

Research shows both benefits and challenges of online discussion as a collaborative learning activity. Online discussion is especially challenging for novice college students who have limited metacognitive skills as well as limited knowledge of the subject domain. With limited metacognitive skills, it can be challenging for novice students to…

This article describes an action research project in which the members of a basic English class for adults over 50 at a Colombian public university undertook the mission of discovering their potentialities as autonomous learners. By means of the reflective use of the language portfolio, the members of this course guided the planning and execution…

Visual intelligence is a key element in the thought processes of the most capable and creative among individuals, and this intelligence is closely related to analogical thinking, a learner's ability to make connections between prior knowledge and newly presented information. This article describes an approach to teaching scientific inquiry at…

Why is it so challenging to provide pre-service teachers with adequate competence to cope with the complexity of the classroom context? Three key difficulties are frequently reported as reducing the effectiveness of teacher education programs: the construction of an integrated body of knowledge about teaching, the application of theories to…

This paper examines how Piaget, Werner, and Gardner differ regarding the roles of cognition, intelligence, and learning in the developmental process. Piaget believes in the predominance of genetic factors. Werner stresses the influence of biological factors, while Gardner proposes that the environment plays a greater influence in how intelligence…

Research to date has demonstrated that networking can be an effective strategy for supporting meaningful learning. However, studies have shown that learners encounter difficulties using it. In an attempt to understand and thus reduce these difficulties, this study examined learners' underlying cognitive processes and activities while networking.…

The interactions between levels of learner prior knowledge and effectiveness of different instructional techniques and procedures have been intensively investigated within a cognitive load framework since mid-90s. This line of research has become known as the expertise reversal effect. Apart from their cognitive load theory-based prediction and…

This paper has five objectives: (a) to review the scientific background of, and major findings reported in, Medical Problem Solving, now widely recognized as a classic in the field; (b) to compare these results with some of the findings in a recent best-selling collection of case studies; (c) to summarize criticisms of the hypothesis-testing model…

The focus of the article is on the complex cognitive process involved in learning the concept of "straightness" in Non-Euclidean geometry. Learning new material is viewed through a conflict resolution framework, as a student questions familiar assumptions understood in Euclidean geometry. A case study reveals how mathematization of the straight…

To foster medical students' diagnostic knowledge a case-based worked example approach was implemented in the context of a computer-based learning environment. Thirty medical students were randomly assigned to the condition "with erroneous examples", and 31 students learned with correct examples. Diagnostic knowledge was operationalised…

The focus of this special issue is on the cognitive load underlying processes of interactive knowledge construction in a wide range of instructional multimedia platforms. Multimedia comprehension involves the parallel processing of auditory-verbal and visual-pictorial channels within working memory. By means of integrating multimodal information,…

We contend that managers make better decisions when they are better able to tap into their vast storehouses of knowledge than their peers can. More specifically, we contend that accessing their tacit knowledge has the most noticeable and positive impact on their decision quality. Furthermore, techniques for better accessing knowledge can be…
