There is a long-standing debate as to whether nonexperimental estimators of causal effects of social programs can overcome selection bias. Most existing reviews either are inconclusive or point to significant selection biases in nonexperimental studies. However, many of the reviews, the so-called "between-studies," do not make direct…

Problem Statement: A number of recent studies on constructivism that have been conducted separately (independently) have arrived at very different results. Throughout the ten-year period in which the constructivist approach has been applied, there have been studies that have researched the effect of the newly-introduced approach on student…

Singaporean students generally perform very well in international tests of mathematics and science. Nonetheless, in multi-cultural Singapore, there exist gaps with the Malays, a minority group in Singapore, systematically lagging behind the other ethnic groups of the Chinese and Indians in many educational performance indicators. While there have…

Improvements in students' learning achievement have lagged behind in low-and middle-income countries despite significant progress in school enrollment numbers. Large-scale early grade reading assessments (e.g., "Annual Status of Education Report" [ASER], 2013; EdData II, n.d.) have shown low reading rates and worryingly high…

The dominance of syntactic studies in linguistics has caused lexis and grammar to be perceived as two distinct categories. With introduction of the paradigm of cognitive linguistics, the studies in syntax have been replaced by those in lexis and concepts. Semantics has come to the fore through the studies in cognitive linguistics, and there has…

Writing-for-publication is a practice that doctoral students should acquire for integration into international research culture. Publication rates and forms of pedagogy supporting the development of publication skills for doctoral students, however, remain inadequate worldwide. Limited data of doctoral student publication from African universities…

The Lisbon European Summit in 2000 has been a milestone in reframing education policies to foster a "knowledge economy", whilst amid the challenges of the new decennium Lifelong Learning (LLL) has been propounded as a powerful lever for attaining "sustainable growth". The present article aims to elucidate the development of an…

Optimal levels of treatment fidelity, a critical moderator of intervention effectiveness, are often difficult to sustain in applied settings. It is unknown whether performance feedback, a widely researched method for increasing educators' treatment fidelity, is an evidence-based practice. The purpose of this review was to evaluate the current…

We describe our experience of using a modified version of the Cochrane risk of bias (RoB) tool for randomised and non-randomised comparative studies. Objectives: (1) To assess time to complete RoB assessment; (2) To assess inter-rater agreement; and (3) To explore the association between RoB and treatment effect size. Methods: Cochrane risk of…

Based on the data collected from 5 prestigious creativity journals, research methodologies and methods of 612 empirical studies on creativity, published between 2003 and 2012, were reviewed and compared to those in gifted education. Major findings included: (a) Creativity research was predominantly quantitative and psychometrics and experiment…

In order to assess the status of the research base that informs "what works" for students with disabilities in higher education, it is necessary to conduct an examination of the methodologies used in the literature. The authors of the current study analyzed the methodological trends across the thirty-year lifespan of the "Journal of…

The purpose of this study is to explore any possible difference among the verb types chosen in articles written in English by the non-natives and natives. In so doing, Halliday's Systemic Functional Grammar (1994) was employed. 80 published articles from the medical sciences field of study were chosen from among which 40 were written by native…

A systematic literature review was undertaken to determine the evidence base underpinning the strategy of Self Directed Support and whether evidence demonstrates that this policy is accessible to everyone with a learning disability. It also sought to identify whether there were any barriers to Self Directed Support for people with severe or…

This study aimed to determine whether there have been shifts in news coverage of sun protection issues over a 12-year period in the context of an evolving skin cancer prevention agenda. A content analysis was performed on all relevant articles (N = 552) published in the two metropolitan daily newspapers in Melbourne, Australia, from 2001 to 2012.…

Students with disabilities experience poorer post-school outcomes compared with their peers without disabilities. Existing experimental literature on "what works" for improving these outcomes is rare; however, a rapidly growing body of research investigates correlational relationships between experiences in school and post-school…
