This study investigates the impact of using the heuristic teaching approach for teaching mathematics to tenth grade students in Jordan. The researchers followed the equivalent pre/post T test two group designs. To achieve the goal of the study, a pre/post- test was constructed to measure student achievement in mathematics. The sample for this…

Historical thinking is an integral part of understanding and doing history, as well as a good example of the kind of critical thinking necessary in today's society. This study, conducted in two phases, investigated ways in which students are brought to this higher level of thinking in the social studies classroom. Data collection occurred…

Dissemination of learning and teaching innovation in higher education requires approaches to change that are socially contextualised, dynamic and self-reflexive. This article, therefore, presents a methodology for dissemination employing an embedding heuristic and engaging in participatory action research. The embedding approach emphasises three…

The clique partitioning problem (CPP) requires the establishment of an equivalence relation for the vertices of a graph such that the sum of the edge costs associated with the relation is minimized. The CPP has important applications for the social sciences because it provides a framework for clustering objects measured on a collection of nominal…

The selection of a subset of variables from a pool of candidates is an important problem in several areas of multivariate statistics. Within the context of principal component analysis (PCA), a number of authors have argued that subset selection is crucial for identifying those variables that are required for correct interpretation of the…

The authors proposed and tested a psychological theory of causal structure learning based on local computations. Local computations simplify complex learning problems via cues available on individual trials to update a single causal structure hypothesis. Structural inferences from local computations make minimal demands on memory, require…

It is commonly held that implicit knowledge expresses itself as fluency. A perceptual clarification task was used to examine the relationship between perceptual processing fluency, subjective familiarity, and grammaticality judgments in a task frequently used to produce implicit knowledge, artificial grammar learning (AGL). Four experiments…

Biological problems in the twenty-first century are complex and require mathematical insight, often resulting in mathematical models of biological systems. Building mathematical-biological models requires cooperation among biologists and mathematicians, and mastery of building models. A new course in mathematical modeling presented the opportunity…

Greenberg (2010) is correct in his assertion that the investigational heuristic used to measure the efficacy of antidepressants is flawed. Robust placebo effects are endemic in the psychiatric literature, particularly in studies of antidepressants, and estimates of placebo responding have increased over time (Rief et al., 2009). In the case of…

In a cross-sectional study with 541 German students (mean age: 12.61 yrs) and (for a subsample of N = 350) one of their parents, developmental conditions for a particular resource of self-regulation ("Flexibility of Goal Adjustment"; Brandtstadter & Renner, 1990) are investigated. Theoretical ¨ arguments and empirical results from…

This study investigated the effect of the Science Writing Heuristic (SWH) approach on grade 9 students' understanding of chemical change and mixture concepts. Four intact classes taught by two chemistry teachers from a Turkish public high school were selected for the study; one class was assigned as the treatment group, and the other class was…

This article describes the development of learning widget on m-learning and e-learning environments. A widget is a small, simple and useful application supporting user-oriented contents. The user may select and install widgets that are convenient as well as an auto-updating application including weather or calendar. These widgets are especially…

Our aim is to present a working model that may serve as a valuable heuristic to predict enduring effects of drugs when administered during development. Our primary tenet is that a greater understanding of neurodevelopment can lead to improved treatment that intervenes early in the progression of a given disorder and prevents symptoms from…

The current study demonstrates how conceptual and procedural knowledge can be used as a heuristic to better understand student math difficulties in order to develop interventions and lay the groundwork for future research. Math interventions were implemented with two elementary students using a nonexperimental single-case design. One student…

This paper attempts to shed light on the role of language in keeping religion relevant to the individual and society in present times. In the context of postmodernity, religion has become more of a meaning system to address the existential questions of the individual. Religious institutions have had to accommodate the changes brought about by a…
