The National Center for Accessible Media has developed a technology and protocol for inserting extended, enhanced descriptions of visually based concepts into artificially paused digital video. These "eDescriptions" describe material not fully explained by a narrator and provide analogies and explanation specifically designed for…

Objective: Adolescent patients' conduct disorder and substance use disorder symptoms are "risky behaviors" with unpredictable rewards and punishments. The authors asked whether such youths also take excessive risks in new situations without prior learning, peer pressure, or intoxication. Method: Subjects were 20 adolescent patients in a program…

In an effort to overcome deficiencies in teaching molecular biology at school, a workshop in an out-of-school laboratory including only authentic experiments was developed. Evaluation of 337 A-level 12th graders followed a quasi-experimental design, with one hands-on group, two non-experimental control groups (at school/in the laboratory), and one…

A study investigated one dimension of metacognition--the knowledge of cognition--in first language (L1) and second language (L2) writing. Subjects were 20 students (10 L1 and 10 L2) in a first level college writing course. A questionnaire elicited subjects' definitions of good writing, their notions of the constituent features of the writing…

The hypothesis for this study assumed that subjects who received a diagram representing the structural relationships of a story would be more likely to solve a new and analogous problem than subjects who received two analogs without a diagram. The 151 graduate students who acted as subjects were randomly assigned to one of four treatments: one or…

Two hypotheses, the cognitive capacity hypothesis and the selective attention hypothesis, try to account for the facilitation effects of prior knowledge activation. They appear to be mutually exclusive since they predict different recall patterns as a result of prior knowledge activation. This study was designed to determine whether the two…

Confirms that able readers have a more well-rounded sense of story structure than disabled readers. Specifically, that able readers demonstrated an ability to tell more elaborate stories than disabled readers. (FL)

Two questions are examined: the relationship between prior to formal experience (high school instruction) and success on university foreign language proficiency tests, and the similarity of prior experience to pass rates for students of varying languages. (LB)

Reports on a study that examined transaction logs of end users of PaperChase searching UM-MEDLINE at the University of Michigan to describe the use of various search features and to determine the effects of search experience on the use of search features. Boolean operators are discussed, and further studies are suggested. (23 references) (LRW)

Compares characteristics of students taking programming-oriented versus applications-oriented higher education courses. Topics include computer engagement, programming experience, computing attitudes, a greater gender imbalance in enrollment on the programming-oriented course, the usefulness of psychometric measures, discriminant function…

This study divided 119 undergraduates into low and high prior knowledge groups and assigned them to three instructional treatments (control, instructor-provided imagery, learner-generated imagery) of the human cardiovascular system. Determined that there was no interaction between student prior knowledge and imaging strategy and that all imagery…

Concerns about students' difficulties in statistical reasoning led to a study which explored form five (14- to 16-year-olds) students' ideas in this area. The study focussed on descriptive statistics, graphical representations, and probability. This paper presents and discusses the ways in which students made sense of information in graphical…

A study analyzed the prior knowledge state of two university populations: students at the Open University (OU) of the Netherlands and students at the University of Limburg (UL). Analysis of the prior knowledge state was based on an extensive analysis of the literature in relation to theories, models, and practice-based strategies about the…

A study was conducted to examine the effects of prescribing the use of some specific reading strategies on comprehension. The effects of such prescription on the interactions among instructional method and a number of individual difference variables were also investigated. Subjects were 140 high school students randomly assigned to read a text…

Compares interactional rules in the lessons of a teacher who taught in a culturally congruent way and one who did not. Concludes that control over topic of discussion was maintained only by the teacher who used culturally congruent interactional patterns, and that the lessons of the other teacher were frequently sidetracked because of conflicts…
