Much of our real-life decision making is bounded by uncertain information, limitations in cognitive resources, and a lack of time to allocate to the decision process. It is thought that humans overcome these limitations through "satisficing," fast but "good-enough" heuristic decision making that prioritizes some sources of…

The Hint Factory is an implementation of our novel method to automatically generate hints using past student data for a logic tutor. One disadvantage of the Hint Factory is the time needed to gather enough data on new problems in order to provide hints. In this paper we describe the use of expert sample solutions to "seed" the hint generation…

The utility of an "ecologically rational" recognition-based decision rule in multichoice decision problems is analyzed, varying the type of judgment required (greater or lesser). The maximum size and range of a counterintuitive advantage associated with recognition-based judgment (the "less-is-more effect") is identified for a range of cue…

Reorientation tasks, in which disoriented participants attempt to relocate objects using different visual cues, have previously been understood to depend on representing aspects of the global organisation of the space, for example its major axis for judgements based on geometry. Careful analysis of the visual information available for these tasks…

Two studies examined certain discrepancies which have been considered important evidence in support of interpersonal comparison (value-adherence) explanations of group induced shifts in choice. (Editor)

Analyzes and categorizes directional factors, and exploratory sequences related to them, via videotaped sessions of two teenage school work groups. Shows stimuli which initiate exploratory sequences are found for all directional factors in problem solving or decision making. Reveals rule-governed or routinized behavior relates to directional…

Twelve orienteers and four military scouts each described a critical incident requiring navigation skills in off-road terrain. Interview analysis generated a taxonomy of the navigator's cognitive model encompassing perception and use of environmental cues, problem-solving and decision-making strategies, and skill level. Contains 38 references. (SV)

The purpose of this study was to describe how one primary teacher of poor and working class rural students promoted small-group dialogue about books and literary concepts. Specifically, we focused on how she guided the students from the beginning of a lesson in ways that later led to dialogue during a videotaped four-day lesson sequence. We…

This handbook is intended to be a self-study guide to the effective use of nine specific instructional strategies proven to improve student achievement. The strategies are: (1) identifying similarities and differences (comparing, classifying, creating metaphors, and creating analogies); (2) summarizing and note taking; (3) reinforcing effort and…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
