The hypothesis defended is that negative data and explicit data result in a type of knowledge that is not to be equated with linguistic competence. The specific claim is that only positive data can effect the construction of an interlanguage grammar comparable to the knowledge system characterizing the results of first-language acquisition. (60…

African-American adolescents (n=195) completed measures on Acquired Immune Deficiency Syndrome (AIDS) knowledge, condoms, health locus of control, vulnerability to human immunodeficiency virus, peer sexual norms, sexual behavior, and contraceptive preferences. Girls were more knowledgeable about AIDS, reported fewer sexual partners, held more…

Studied sexual knowledge among Norwegian adolescents (n=1,855) aged 17-19 years. Found knowledge gaps among adolescents on sexual physiology and anatomy, sexually transmitted diseases, and fecundation/contraception. Level of sexual knowledge was higher among girls than boys and increased with increasing age. Sexual knowledge did not predict…

Authentic achievement relies on three restructuring criteria. Students construct meaning and produce knowledge, use disciplined inquiry to construct meaning, and aim their work toward producing discourse, products, and performances possessing value beyond school success. Five standards for rating instruction involve degrees of higher order…

This paper discusses the two important domains affecting the success of learning strategy training for students with learning disabilities or other mild handicaps: students' knowledge of critical skills and information potentially related to strategy use, and students' motivation to learn and use the strategy. The paper presents an eight-stage…

Used 1988 Australian national population survey to examine drug information needs. Results indicated almost one-half of respondents believed that they had an adequate amount of information about drug and alcohol services available. Drug users expressed greater desire for information and willingness to use variety of welfare and social support…

Measures how much voters learned about the issue positions of the 1988 presidential candidates and the images formed from campaign coverage and other information. Finds the debates influential on knowledge; higher levels of education and campaign interest related to more issue knowledge; and image knowledge predicted by party loyalty. Concludes…

Applies Gresham's Law ("bad money drives out good") to educators' overreliance on technology. Introducing more advanced "learning" technology without a concomitant emphasis on knowledge acquisition allows some students to operate at increasingly lower thought levels. Higher order thought processes will be displaced (and…

Survey investigated female college students' knowledge about toxic shock syndrome (TSS), noting relationships between knowledge, self-perceived risk of developing TSS, and menstrual product use. Data analysis indicated knowledge about TSS was inadequate, particularly among young females. Neither risk perception nor product use were mediated by…

Sexual behavior, knowledge of sexually transmitted disease and condoms, and condom use was studied among 116 African American and white incarcerated adolescents in Seattle (Washington). Results indicate that these adolescents are at high risk and suggest that programs designed solely to increase knowledge are unlikely to effect behavior change.…

Arguing that cognitive development involves both conceptual and semiotic achievements, the authors emphasize the distinctness of semiotic issues and develop a differentiated appreciation of semiotic aspects of cognition, particularly in elementary mathematics cognition. Semiotic analyses are provided of differences between counting, adding, and…

A metrics and mapping framework is proposed to account for how heuristics, domain-specific reasoning, and intuitive statistical induction processes are integrated to generate estimates. Results of 4 experiments involving 188 undergraduates illustrate framework usefulness and suggest when people use heuristics and when they emphasize…

Describes two aspects of metacognition, knowledge of cognition and regulation of cognition, and how they relate to domain-specific knowledge and cognitive abilities. It is argued that metacognitive knowledge is multidimensional, domain-general in nature, and teachable. Four instructional strategies are described for promoting the construction and…

Explores understanding of chance measurement and how this develops over time through the analysis of response data collected in 1993, 1995, and 1997. Analyzes this data to document changes in levels of observed student outcomes using the Structure of the Observed Learning Outcome (SOLO) developmental model. Results indicate no improvements in…

Examines the range of knowledge about retirement-related issues that exists among various employee groups within a particular organization. Finds that education was a strong predictor in determining employees' knowledge. Discusses implications for future research regarding the development of materials designed to educate employees about…
