This paper presents five emergent categories of learning with mobile applications (apps) and suggests an overarching profile to characterize such apps. The categories are organized into three levels. The micro level focuses on interactions and includes (i) interaction with the device and (ii) interaction with the environment. The intermediate…

Computer-based problem-solving examinations in immunology generate graphic representations of students' search paths, allowing evaluation of how organized and focused their knowledge is, how well their organization relates to critical concepts in immunology, where major misconceptions exist, and whether proper knowledge links exist between content…

Explores situated cognition, arguing that the construct of "community of practice" is useful as an analytical lens in which to examine the domain of educational technology. Traces the history of educational technology, and how it is embedded in a larger social and political environment that excludes those who exist on the margins from…

The work of connectionist researchers is examined in order to understand better the implications for modeling second language learning processes. Connectionism is a biologically-oriented framework for understanding complex behavior, and provides a modeling tool (computer simulation) that behaves and learns without rules being explicitly wired into…

The first of three articles on the ways in which people formulate their observations, this paper considers the basic assumptions of both syntactic and paradigmatic models of cognition and their applications in natural (i.e., human) and artificial (i.e., computer) information processing. The analysis begins with background information on the nature…

This exploratory study of children's use of electronic text systems drew upon site visits, interviews, and data compilations for an overview and synthesis of issues. Systems studied included Green Thumb (videotext, Kentucky); Channel 2000 (videotext, Ohio); KCET (teletext, California); WETA (teletext, Washington, D.C.); QUBE (interactive cable,…

A future, automated, interactive, knowledge delivery system for use by researchers was tested using a manual cognitive model. Conceptualized from schema/frame/script theories in cognitive psychology and artificial intelligence, this hypothetical system was simulated by two psychologists who interacted with four researchers in microbiology to…

The feasibility of the administration, scoring, and reporting of an on-line concept mapping system has been studied in collective research in which concept map construction systems were designed to allow students individually and collaboratively to construct concept maps on the computer to measure content understanding and collaboration. The study…

This paper describes NEOMYCIN, a computer program that models one physician's diagnostic reasoning within a limited area of medicine. NEOMYCIN's knowledge base and reasoning procedure constitute a model of how human knowledge is organized and how it is used in diagnosis. The hypothesis is tested that such a procedure can be used to simulate both…

Measuring student writing skills can be done holistically, by ranking compositions without enumerating their linguistic, rhetorical, or information features, or atomistically, by viewing compositions as collections of these features. A variety of holistic approaches, including primary score testing, exist. Though their reliability has been…
