This study aimed to describe the profile of the students' social skills of Bengawan Solo nature elementary school. The study was qualitatively conducted as a case study. The participants were teachers and students who were chosen by employing a purposive sampling technique. The data were obtained through observations, questionnaires, interviews,…

In this article, I comment on the potential benefits and limitations of open science reforms for improving the transparency and accountability of research, and enhancing the credibility of research findings within communities of policy and practice. Specifically, I discuss the role of replication and reproducibility of research in promoting better…

Group design research studies can provide evidence to draw conclusions about "what works," "for whom," and "under what conditions" in special education. The quality indicators introduced by Gersten and colleagues (2005) have contributed to increased rigor in group design research, which has provided substantial…

There has been considerable recent interest in methods of determining sample size for qualitative research a priori, rather than through an adaptive approach such as saturation. Extending previous literature in this area, we identify four distinct approaches to determining sample size in this way: rules of thumb, conceptual models, numerical…

This computer simulation study evaluates the robustness of the nonparametric Levene test of equal variances (Nordstokke & Zumbo, 2010) when sampling from populations with unequal (and unknown) means. Testing for population mean differences when population variances are unknown and possibly unequal is often referred to as the Behrens-Fisher…

Background: Experiences of people with intellectual disability are often reported by proxy, excluding the person's own perception. To assist people with intellectual disabilities ability to communicate their own experiences, the current study explored the feasibility, reliability and validity of experience sampling methods (ESMs) for people with…

Purpose: The goal of this study was to determine whether the results obtained from a 25-utterance conversational language sample were as reliable as those obtained from a 50-utterance sample. Method: Robust conversational language samples from 220 children with typically developing language (106 boys, 114 girls) ranging in age from 3;2 to 7;10…

In the context of cross-sectional surveys, the scope of research on the impact of response enhancing strategies on sample composition and nonresponse bias is vast. This topic has rarely been addressed for panel studies, however, although these are becoming an increasingly important data source in social research. In this article, we evaluate the…

Traditional psychometric guidelines suggest that at least several hundred respondents are needed to obtain accurate parameter estimates under the Rasch model. However, recent research indicates that Rasch equating results in accurate parameter estimates with sample sizes as small as 25. Item parameter drift under the Rasch model has been…

Saudi Arabia has produced more peer-reviewed research in the past 10 years than ever before (El-Showk, 2016). The country is leading its Arab counterparts in the annual number of both published scientific research and obtained patents. A review of the published research across topics and fields of study, the research designs used, and the…

The study aimed to uncover the general trends of published researches undertaken in the field of Social Studies Education. To this end, SSCI, SCI-EXPANDED, A&HCI, CPCI-S, CPCI-SSH, and ESCI indexed journals were scanned through the Web of Science database. In the study, 55 articles which were suitable for scope of the research, and published…

Although educational researchers will acknowledge that they have a moral imperative to avoid harming their participants whilst carrying out research, it does not necessarily mean that they can describe the nature of what this harm might be or how it can be recognised and so avoided. This is particularly important for those working with vulnerable…

Q methodology (Q) offers an empirical method for studying subjectivity and revealing multiple divergent viewpoints. Q's technique is the sorting of statements related to the topic and its method is the factor analyzing of those sorts to group people with similar viewpoints. Mixed information exists about Q methodologists' practice at the…

Purpose: The purpose of this study was to document whether mean length of utterance[subscript SUGAR] (MLU[subscript S]), total number of words (TNW), clauses per sentence (CPS), and/or words per sentence (WPS) demonstrated age-related changes in children with typically developing language, aged 7;0-10;11 (years;months). Method: Participants were…

The purpose of this research is a comprehensive review of studies towards educational data mining (EDM) in Turkey. For the purpose of this study, graduate theses and articles conducted in Turkey were examined in detail. As a result of the literature review, 48 studies were analyzed in the context of the data mining purpose, the technique used in…
