RAND has explored, among other math-related topics, mathematics curricula in primary education and the role of mathematics in innovation, e.g., in the evaluation of new medical technologies or the development of methodologies such as game theory.
Report
This paper describes a new approach and associated search schemes for optimization under uncertainty. Analysts can apply this method to a problem with a significantly larger number of decision variables, uncertain parameters, and uncertain scenarios.
Journal Article
Comparative effectiveness research will be hard to use appropriately because context and emotion often dominate a patient's rational decisionmaking and because therapies are provided in different health care environments, making small differences between therapies basically meaningless.
Journal Article
Electronic searches typically yield far more citations than are relevant, and reviewers spend a substantial amount of time screening titles and abstracts to identify potential studies eligible for inclusion in a review.
Multimedia
On May 14, 2009, Titus Galama discussed the reality of U.S. competitiveness in science and technology and whether gains by China, India, and other nations are affecting America's chances of remaining a scientific leader.
Journal Article
The mean value of travel time savings obtained from a random parameters logit model estimated using the respondents who received the D-efficient design survey was closer to what is typically found in the literature.
Journal Article
This randomized, controlled field trial estimated the causal impact of a technology-based geometry curriculum on students' geometry achievement, as well as their attitudes toward mathematics and technology.
Journal Article
In this study the authors use data from the Early Childhood Longitudinal Survey third- and fifth-grade samples to investigate teacher judgments of student achievement and other measures.
Journal Article
Contrary to previous conclusions, the authors find that respondents do not tend to overweight private information when updating beliefs.
Journal Article
Game theory and other simulations show that, if potential criminal offenders are sufficiently deterrable, increasing the conditional probability of punishment (given violation) can reduce the amount of punishment actually inflicted, by "tipping" a situation from its high-violation equilibrium to its low-violation equilibrium.
Journal Article
This study explored the relationship between mathematics and science achievement and reform-oriented teaching over a 3-year period.
Report
England reformed its elementary math curriculum in 1999 to improve educational outcomes. Evaluations of the reforms were generally positive, but the evidence of success and value for money was more difficult to confirm.
Report
Describes a method for designing a sample of Air Force personnel to participate in an online survey of cultural attitudes.
Announcement
The U.S. Department of Education has awarded the RAND Corporation a $6 million grant to conduct a five-year study of the effectiveness of a technology-based mathematics curriculum created by Carnegie Learning, Inc., of Pittsburgh.
Journal Article
Basing outcome assessment on matching or regression modeling yielded similar findings on hospital ranking but moderate level of agreement on quality.
Journal Article
Conclusions about individual teachers' performance based on value-added models can be sensitive to the ways in which student achievement is measured.
Research Brief
This research brief summarizes a three-year study of the relationship between reform-oriented instruction and student performance in mathematics and science.
Report
Presents findings of a multiyear study of the effectiveness of reform-oriented science and mathematics teaching (practices for engaging students as active participants in their own learning and enhancing the development of complex cognitive skills).
Commentary
Published commentary by RAND staff: Making Europe a Home Fit for the Next Einstein, in the Financial Times.
Journal Article
This electronic tool for individualized assessment of VTE risk identified the perceived risk of thrombosis and the appropriate prophylactic approach.
