Results of analysis of responses to a first-year undergraduate engineering activity are presented. Teams of students were asked to develop a procedure for quantifying the roughness of a surface at the nanoscale, which is typical of problems in Materials Engineering where qualities of a material need to be quantified. Thirty-five teams were…

The main purpose of this study is to investigate the related factors that affect the usage of educational technology in primary schools. This study depends on literature analysis and the questionnaire to collect data. Specifically, the items employed in this study were derived from the teachers' and school administrators' perceptions of using…

Educational stakeholders have continued to express concerns over the poor academic performance of Nigerian students at virtually all levels of academic engagements. This paper investigated personal factors as predictors of students' academic performance in the South-Western Nigeria. The study employed the ex post facto design using a survey design…

The study aims to explore the nature of selected domains of self-concept (namely behaviour, Intellectual and school status, physical appearance and attributes, anxiety, happiness and satisfaction) of the sighted adolescents and the adolescents with a visual impairment. The sample (N = 160) have been drawn by simple random sampling from 100 sighted…

School leadership, one of the most important aspects of school improvement, has not received much attention from either policymakers or researchers in Turkey despite many countries embrace creating and developing effective leaders as one of the important first steps to improve their education. This research looked at the instructional leadership…

In this article, we consider estimation of parameters of random effects models from samples collected via complex multistage designs. Incorporation of sampling weights is one way to reduce estimation bias due to unequal probabilities of selection. Several weighting methods have been proposed in the literature for estimating the parameters of…

Some researchers have argued for the use of or have attempted to make use of randomization tests in single-subject research. To address this tide of interest, the authors of this article describe randomization tests, discuss the theoretical rationale for applying them to single-subject research, and provide an overview of the methodological…

The current study addressed some of the methodological shortcomings of previous studies on internet addiction. The main purpose of the study was to determine if two different internet addiction assessments would identify the same individuals as addicted to the internet. A total of 224 undergraduate internet users were surveyed using a stratified…

The distance between nonparametric and parametric item characteristic curves has been proposed as an index of goodness of fit in item response theory in the form of a root integrated squared error index. This article proposes to use the posterior distribution of the latent trait as the nonparametric model and compares the performance of an index…

This article describes two methods for obtaining the standard errors of two commonly used population invariance measures of equating functions: the root mean square difference of the subpopulation equating functions from the overall equating function and the root expected mean square difference. The delta method relies on an analytical…

Science education in Malaysia nurtures a science and technology culture by focusing on the development of individuals who are competitive, dynamic, robust, resilient and able to master scientific knowledge and technological competency. To this end, the science curriculum in Malaysia gives conscious emphasis to the acquisition of scientific skills…

This paper provides a guide to calculating statistical power for the complex multilevel designs that are used in most field studies in education research. For multilevel evaluation studies in the field of education, it is important to account for the impact of clustering on the standard errors of estimates of treatment effects. Using ideas from…

This article uses meta-analyses published in "Psychological Bulletin" from 1995 to 2005 to describe meta-analyses in psychology, including examination of statistical power, Type I errors resulting from multiple comparisons, and model choice. Retrospective power estimates indicated that univariate categorical and continuous moderators, individual…

Little is known about the effects of various planning and revising conditions on composition quality in experimental or TESOL education research. This study examined the effects of planning conditions (planning, prolonged planning, free writing, and control), subplanning conditions (task-given, task-content-given, and…

Progress in International Reading Literacy Study (PIRLS) provides international comparative data about students' reading achievement after four years of primary schooling, while also measuring trends over time, monitoring curricular implementation, and identifying promising instructional practices. Conducted on a regular 5-year cycle, PIRLS has…
