Design briefs are plausible situations in which students are asked to solve problems given limited materials, a specific time frame, and a number of rules and limitations. It is the author's contention that the design brief, an established format in technology education, can serve as a unique approach to extend and assess everyday science…

Adaptive expertise, an individual's ability to perform flexibly and innovatively in novel and unstructured situations, could have particular relevance for expedition and outdoor leaders. This element may be recognized in leadership practitioners who are able to act more effectively when problem-solving in complex, ambiguous and unpredictable…

We consider two different algebra topics that can be taught in a typical college class. With each topic, we demonstrate how a teacher can delve deeper using a computer algebra system.

In beginning chemistry classes, students are taught a variety of techniques for balancing chemical equations. The most common method is inspection. This paper addresses using a system of linear mathematical equations to solve for the stoichiometric coefficients. Many linear algebra books carry the standard balancing of chemical equations as an…

We study four non-Newtonian fluid mechanics problems using Mathematica[R]. Constitutive equations describing the behavior of power-law, Bingham and Carreau models are recalled. The velocity profile is obtained for the horizontal flow of power-law fluids in pipes and annuli. For the vertical laminar film flow of a Bingham fluid we determine the…

Background: Within the context of current legislation relating to mental capacity in adults, the capacity of people with intellectual disabilities to consent to take part in research studies and the impact of different forms of information provision was experimentally investigated. Materials and methods: A questionnaire measure of ability to…

Gaps between teaching practices and research recommendations have been well documented. One challenge for research is in understanding the processes and systems that promote a bridging of these gaps. A year-long study with four primary teachers documented ten support mechanisms, or connection levers, that the teachers raised as important for…

This article focuses on the Problem-Solving Cycle (PSC), a model of professional development designed to assist teachers in supporting their students' mathematical reasoning. Each PSC is a series of three interrelated workshops in which teachers share a common mathematical and pedagogical experience, organized around a rich mathematical task.…

A holiday quilt project in a kindergarten classroom becomes a focus for exploring patterns, shapes, measurement, spatial relationships, and number sense. Cooperative group work, problem solving, and communication of mathematical ideas enhance the completion of the project. (Contains 5 figures.)

This study explored Ndebele culture of Zimbabwe's views of giftedness. Using questionnaire narratives, data were collected from thirty Zimbabwean teachers and lecturers of Ndebele cultural background. The study established that Ndebele culture views giftedness as an unusually outstanding ability blessed in an individual from birth, which manifests…

We examined relationships between abuse, coping, and psychological health among 143 women who had experienced abuse in adult relationships. Measures included characteristics of the abuse, problem-focused and emotion-focused coping, Sense of Coherence, and four measures of psychological wellbeing--the SF-36 Mental Component Scale, the General…

The present study examined the role of parenting styles in the experience and expression of homesickness, and the way of coping with the feelings involved. Using a sample of 670 first year college and university students, aged 16 to 25, we tested three hypotheses: (1) authoritarian, permissive as well as uninvolved parenting are associated with…

Developmental theories presume dramatic differences in the coping of the young and old, but with little empirical support. In this study, five demographically matched groups: Pre-Teens (9-12 years, n = 153), Early Teens (13-15, n = 141), Late Teens (16-18, n = 151), Younger Adults (20-29, n = 133), and Older Adults (30-70, n = 133) completed…

Although worry is considered to be the key feature of generalised anxiety disorder, it has its own unique properties. The study aimed to investigate the extent to which intolerance of uncertainty, poor problem-solving confidence, positive beliefs about worry and negative thinking style, predicted worry, both individually and in combination, once…

In higher education, instructors' choices of both curricular material and pedagogy are determined by their beliefs about learning and teaching, the values of their profession, and perceived external constraints. Dissemination of research-based educational reforms is based on assumptions about that mental structure. This study reports the initial…
