Quantitative literacy, the ability to discriminate between good and bad data, the disposition to use quantitative information to think through complex problems are capacities that educators across fields should be helping students develop. Burke leads the reader to this conclusion through an extended example of income distribution, clarified and…

We believe a lack of transparency undermines both the credibility of, and interest in, stated choice studies among policy makers. Unlike articles reporting the results of contingent valuation studies, papers in the stated choice literature rarely present simple tabulations of raw response data (that is, a table or graph showing the percentage of…

This paper, the second of a two part article, expands on an idea that appeared in literature in the 1950s to show that by restricting the domain to those complex numbers that map onto real numbers, representations of functions other than the ones in the real plane are obtained. In other words, the well-known curves in the real plane only depict…

The present study investigated the extent to which providing students with individualized performance feedback informed and directed their learning behavior. Individualized performance feedback was delivered to students using curriculum-based measurement progress indicators, either as a visual representation of ongoing performance in the form of a…

Developing good record-keeping habits is essential for organizing, processing, and communicating experimental results objectively. Therefore, the authors designed an interactive method of teaching first graders to record, organize, and interpret data as they studied the life cycle of the spotted salamander ("Ambystoma maculatum"). In their…

Most of the research on bargaining has focused on individuals bargaining against other individuals. This paper discusses two experiments in which the bargaining processes and outcomes of bargaining teams were compared to those of individual bargainers. Individuals bargained against a single other in the first experiment, while a two-person team…

Results of interviews with 167 school administrators, teacher association presidents, and chief school officers in three New York counties indicate that Southern Tier educators favor educational change, but are hampered in planning by insufficient financial support, apathy and resistance, and inadequate organizational structures. Specific…

Relations on a finite set V are viewed as weighted graphs. Using the language of graph theory, two methods of partitioning V are examined: selecting threshold values and applying them to a maximal weighted spanning forest, and using a parametric linear program to obtain a most adhesive partition.

Discusses three techniques that can help counselors plot client growth over time: the split-middle method, the two standard deviation rule, and the frequency histogram. (Author/BH)

Discusses a graphical method of teaching elementary collisions. This method yields universal solutions to head-on collision problems with the target at rest by the use of parameters and graphical analysis at a mathematical level that beginning physics students can understand. The author concludes that this method is better than the traditional…

Three categories of graphs are discussed: real, representational or pictoral, and symbolic. Real graphs are very useful for teaching basic graphing concepts to K-6 students. Three steps in graph making are described: ask the question; collect and organize information; label the graph. A detailed guide to several graphing activities is included.…
