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.
