Recent guidance on the treatment of missing data in experiments advocates the use of sensitivity analysis and worst-case bounds analysis for addressing non-ignorable missing data mechanisms; moreover, plans for the analysis of missing data should be specified prior to data collection (Puma et al., 2009). While these authors recommend only that…

Covariate adjustment can increase the precision of estimates by removing unexplained variance from the error in randomized experiments, although chance covariate imbalance tends to counteract the improvement in precision. The author develops an easy measure to examine chance covariate imbalance in randomization by standardizing the average…

The accumulation of scientific knowledge greatly depends upon the critical review of experimental findings by ones peers. In single case design research, experimenters present findings with graphical displays of data and narrative description of a visual analysis. To aid in efficient and accurate description of experimental findings, the research…

Research Findings: Research with young children is a complex enterprise and often fraught with ethical and practical dilemmas. This paper seeks to discuss the experience of an Australian early childhood academic undertaking research with children 3 to 6 years of age. It draws upon a series of projects that examine young children's standpoints on…

The study aimed to determine the effect of the implementation of the program "Manage your Talent" on assertive communication and teamwork competences. A quasi-experimental research design was used with pretest - intervention - post-test with control group. The sample included 28 supervisors from a private company, 13 in the experimental…

Effective knowledge translation processes are critical for the development of evidence-based public health policy and practice. This paper reports on the design and implementation of an innovative approach to knowledge translation within a mixed methods study on lay involvement in public health programme delivery. The study design drew on…

In recent years, more and more researchers in science education have been turning to the practice of combining qualitative and quantitative methods in the same study. This approach of using mixed methods creates possibilities to study the various issues that science educators encounter in more depth. In this content analysis, I evaluated 18…

School personnel make a variety of decisions within multitiered problem-solving frameworks, including the decision to assign a student to group-based support, to design an individualized support plan, or classify a student as eligible for special education. Each decision is founded upon a judgment regarding whether the student has responded to…

We explore in this paper if automated scaffolding delivered via a pedagogical agent within a simulation can help students acquire data collection inquiry skills. Our initial analyses revealed that such scaffolding was effective for helping students who initially did not know two specific skills, designing controlled experiments and testing stated…

This study reviews a selected sample of 274 research articles on ELT, published between 2005 and 2015 in Turkish contexts. In the study, 15 journals in ULAKBIM database and articles from national and international journals accessed according to convenience sampling method were surveyed and relevant articles were obtained. A content analysis was…

The aim of this research is to determine the effect of the different teaching methods, on seventh-grade students' academic achievement and scientific attitudes. The research was carried out using quasi-experimental methods. The research sample consisted of 84 seventh grade students studying in three different classes. One of these classes an…

In the present era, education has emerged as a countrywide mission in developed and developing countries. Countries are utilizing their energies to deal with the transformations forthcoming in higher education. The research under investigation, reviews the global developments in the area of higher education (HE) all over the world and surveys the…

School nurses are tasked with the critical job of keeping students safe and well. Due to competing demands for resources in schools, the impact of school nurses must be demonstrated to secure their jobs. A systematic review of the literature from 1937 to 2013 was conducted to show the efficacy of school nursing activities in American elementary…

The science-to-service problem continues to taunt the field of education (Fixsen, Blasé, Naoom, & Wallace, 2009). As an academic discipline, the field requires knowledge generation that adds to or deepens theoretical understandings. As a profession, knowledge generation that solves local problems and supports continuous improvement is…

This article argues that research on teacher preparation over the last 100 years can be understood in terms of the major questions that researchers examined. The analysis is guided by the framework of "research as historically situated social practice," which emphasizes that researchers' interests, commitments, and social experiences…
