The focus of this study was connections among 3 aspects of mathematical cognition at 2nd grade: calculations, word problems, and prealgebraic knowledge. We extended the literature, which is dominated by correlational work, by examining whether intervention conducted on calculations or word problems contributes to improved performance in the other…

The paper shows how the methodology for a pedagogical experiment can be improved through including the pre-research stage. If the experiment has the form of a test procedure, an improvement of methodology can be achieved using for example the methods of statistical and didactic analysis of tests which are traditionally used in other areas, i.e.…

This study tested whether the gender intensification hypothesis applies to relations between multiple domain-specific self-concept facets and self-esteem. This hypothesis predicts gender-stereotypic differences in these relations and assumes they intensify with age. Furthermore, knowledge about gender-related or age-related differences in…

The aim of this study was to examine the effects of asynchronous (background) music on senior students' motivation and lesson satisfaction at the situational level. A counterbalanced mixed-model design was employed with two factors comprising condition (three levels) and gender (two levels). Two hundred students (82 boys, 118 girls; M [subscript…

The International Test Commission's "Guidelines for Translating and Adapting Tests" (2010) provide important guidance on developing and evaluating tests for use across languages. These guidelines are widely applauded, but the degree to which they are followed in practice is unknown. The objective of this study was to perform a…

This brief report assesses the validity of applying the adolescent-based developmental assets model to emerging adults. Developmental assets are specific constructs which predict future success, including positive individual characteristics and environmental resources. The researchers developed a self-report survey based on a subset of the assets…

The principle of "inversion," that a + b - b "must" equal a, is a fundamental property of arithmetic, but many children fail to apply it in symbolic contexts through 10 years of age. We explore three hypotheses relating to the use of inversion that stem from a model proposed by Siegler and Araya (2005). Hypothesis 1 is that…

The facilitative effect of retrieval practice, or testing, on the probability of later retrieval has been the focus of much recent empirical research. A lesser known benefit of retrieval practice is that it may also enhance the ability of a learner to benefit from a subsequent restudy opportunity. This facilitative effect of retrieval practice on…

Funded by the UK JISC Institutional Innovation Programme, the Augustine House Experiment sets out to investigate how the location sensing data collected over students' uses of the iBorrow notebooks can be visualised to reveal aspects of the new learning landscape during a 1-week sensing period. Indoor real-time location sensing technologies are…

This dataset contains the results of a quasi-experiment, testing Karl Pearson's "drunkard's walk" analogy for an abstract random walk. Inspired by the alternate hypothesis that drunkards stumble to the side of their dominant hand, it includes data on intoxicated test subjects walking a 10' line. Variables include: the…

In 2 experiments, we explored differences in cognitive control at retrieval on a final test to better understand the mechanisms underlying the powerful boost in recall of previously tested information. Memory retrieval can be enhanced by front-end control processes that regulate the scope of retrieval or by later processes that monitor retrieval…

Intelligent decision systems have the potential to support and greatly amplify human decision-making across a number of industries and domains. However, despite the rapid improvement in the underlying capabilities of these "intelligent" systems, increasing their acceptance as decision aids in industry has remained a formidable challenge.…

Many organizations find selecting a leader to be highly challenging. Investigators have found and admit that the study of leadership is a very complex phenomenon that cannot be easily captured and explained in a manner that could lead to a final description about leadership or offer clear steps on how to choose the right leader. Among the many…

In the 21st century, women and leadership have been a global topical issue, especially with countries trying to interpret and implement the millennium development goals, and with increased awareness of human rights. In Africa, political leadership among women has had its own challenges that range from social, cultural and even economic factors. In…

This study examined the extent to which school outdoor activities could enhance senior secondary (SS) two students' achievement in ecology. Non randomized pre test post test control group Quasi-experimental design was adopted. A sample of 160 SS II students from 4 co-educational schools in Jalingo metropolis, Taraba State Nigeria was used. A 40…
