A cross-curricular structured-probe task-based clinical interview study with 44 pairs of third year high-school mathematics students, most of whom were high achieving, was conducted to investigate their approaches to a variety of algebra problems. This paper presents results from three problems that were posed in symbolic form. Two problems are…

In this paper "Derive" functions are provided for the computation of the Moore-Penrose inverse of a matrix, as well as for solving systems of linear equations by means of the Moore-Penrose inverse. Making it possible to compute the Moore-Penrose inverse easily with one of the most commonly used Computer Algebra Systems--and to have the blueprint…

Purpose--There can be little doubt about the importance and relevance of quality for any service industry. One of the most influential contributors to service quality developments was W. Edwards Deming (1900-1993). An important component of Demings philosophy is reflected in his 14-principles for transforming a service as they indicate what…

This article describes an innovative strategic tools course designed to enhance the problem-solving skills of marketing majors. The course serves as a means of preparing students to capitalize on opportunities afforded by a case-based capstone course and to better meet the needs and expectations of prospective employers. The course format utilizes…

This qualitative study examined the relationship between young deaf children's level of mathematics ability ('high" and "low," as defined by test score on the Test of Early Mathematics Ability-3) and opportunities available for the construction of early mathematics knowledge during a problem-solving task implemented by their parents. Findings…

Implementation integrity is a potentially critical issue for problem-solving teams (PST) and most response-to-intervention models. The current study hypothesized that providing performance feedback, which has consistently been shown to increase implementation integrity, to PSTs would enhance the procedural integrity of the process. The PSTs for…

Within the scope of this study, the effectiveness of two kinds of instructional support was evaluated with regard to the learner's interests. Two versions of a simulation program about the respiratory chain were developed, differing only in the kind of tasks provided for instructional support: One version contained problem-solving tasks, the other…

The aim of this study was to investigate to what extent students with mild mental retardation exhibit strategic behaviour during problem solving and to investigate the relationships between the ongoing behaviours examined and the students' respective performance. Eleven students with non-organic mild mental retardation participated in the study.…

The authors examined regulation of the discrete emotions anger and sadness in adolescents through older adults in the context of describing everyday problem situations. The results support previous work; in comparison to younger age groups, older adults reported that they experienced less anger and reported that they used more passive and fewer…

Members of the school library media profession are fortunate to have new direction from two organizations that seek to define the type of educational experiences that will best benefit students as they prepare to continue to learn, live, and work in the 21st century. Both organizations, American Association of School Librarians (AASL) and the…

In this paper it is proposed that the prefrontal lobe participates in two closely related but different executive function abilities: (1) "metacognitive executive functions": problem solving, planning, concept formation, strategy development and implementation, controlling attention, working memory, and the like; that is, executive functions as…

Background: Research has demonstrated that working collaboratively can have positive effects on children's learning. While key factors have been identified which influence the quality of these interactions, little research has addressed the influence of children's achievement goals on collaborative behaviour. Aims: This paper investigates the…

Six experiments examined children's ability to make inferences using temporal order information. Children completed versions of a task involving a toy zoo; one version required reasoning about past events (search task) and the other required reasoning about future events (planning task). Children younger than 5 years failed both the search and the…

Teamwork and problem-solving skills have frequently been identified by business leaders as being key competencies; thus, teaching methods such as problem-based learning and team-based learning have been developed. However, the focus of these methods has been on teaching one skill or the other. A key argument for teaching the skills concurrently is…

The paper proposes a framework for collaborative knowledge production in order to enhance the amount and quality of knowledge in the field of organizational development (OD). We distinguish three types of actors that offer development services for work organizations: academic R&D units, training and educational institutes and management…
