Despite the rising number of cases of HIV in adults over age 50, older persons rarely are considered to be at risk for HIV/AIDS, and even though they may be involved in risky behavior, such as unprotected penetrative sex, they may not consider themselves vulnerable to becoming infected. Informed awareness of risk is essential to making positive…

This paper relates the story of two professors that have made a bridge between the two cultures, science and humanities. They teach a humanities course together in which they explore the nature of the two cultures, their differences and their commonalities. The processes of team-building and planning produced five heuristic questions for the…

The main distinction between the overlapping fields of molecular biophysics and biochemistry resides in their different approaches to the same problems. Molecular biophysics makes more use of physical techniques and focuses on quantitative data. This difference encounters two difficult pedagogical challenges when teaching molecular biophysics to…

Traditional views of critical thinking instruction focus on teaching students to develop skeptical responses to the texts they read. Genuinely powerful and generative forms of critical thinking, however, require students to read creatively as well. To balance the rigor of analysis and exorbitance of creativity, a freshman honors seminar was…

Grade-equivalent scores are widely used in the school system in reporting students' performance on standardized achievement tests. This paper explores how grade equivalent scores are calculated and interpreted. In addition, the paper examines the limitations of grade-equivalent scores through the use of small heuristic data sets. A…

As part of an effort to improve community college algebra students' ability to solve word problems, a study was undertaken at Florida's Manatee Community College to determine the effects of using heuristic instruction (i.e., providing general rules for solving different types of math problems) in combination with the TI-92 calculator. The TI-92…

Contemporary findings of brain research and language function can be analyzed and related to the teaching of creative and critical thinking and active learning through writing. A great deal of work has been carried out concerning the integration of the cerebral hemispheres for heuristic procedures in writing invention. In the integrated brain, the…

Issues and elements of case study research are explored and illustrated with the example of a case study of a kindergarten in a suburb of Tokyo (Japan). Case study research is a type of qualitative research that concentrates on a single unit or entity, with boundaries established by the researcher. The case is an example drawn from a larger class,…

The nature of percentile ranks scores is explored using concrete heuristic examples. It is explained why arithmetic operations require measurement on equal-interval scales, and that percentile ranks are not measured on equal-interval scales and therefore may not be added or averaged. The consequences of inappropriately adding percentile ranks are…

Methods are proposed for the construction of weakly parallel tests, that is, tests with the same test information function. A mathematical programing model for constructing tests with a prespecified test information function and a heuristic for assigning items to tests such that their information functions are equal play an important role in the…

In an effort to more clearly define the engineering method, this document attempts to draw distinctions between engineering and science. Part I, "Some Thoughts on Engineering," discusses strategies that engineers employ to solve problems, and the characteristics of the types of engineering problems. Part II, "The Principal Rule of the Engineering…

A number of studies have reported that there is a strong tendency to ignore base-rate information in favor of individuating information, except when the former can readily be incorporated into a causal schema. In this study, students in eight undergraduate classes were given problems in which the base-rate information was either causal or…

This study investigated several aspects of a teaching experiment which focused on five seventh grade students' performance on nonroutine number theory problem-solving with a close look at the role of heuristics, concrete models, and the relationships between these variables. In the experiment, students were given a series of lessons on number…

While each English department will establish its own set of assumptions appropriate for its objectives and programs, the new rhetoric can bring some coherence to the teaching of writing and literature by providing students with reliable strategies for reading literature as well as writing. In teaching literature teachers need to demonstrate the…

The integration of content area writing instruction into the history curriculum has been a slow process. A history course at Ohio University (Athens) offers students experience in writing the type of materials written by practicing historians: book reviews, journal articles, and articles for encyclopedias and biographical dictionaries. Such short…
