As part of an interview protocol investigating teachers' pedagogical content knowledge (PCK) in statistics, 40 teachers were presented with a newspaper article reporting a phone-in survey about the legalisation of marijuana. The article and a question about the reliability of the sample had earlier been used in student surveys, and three student…

The 3PL model is a flexible and widely used tool in assessment. However, it suffers from limitations due to its need for large sample sizes. This study introduces and evaluates the efficacy of a new sample size augmentation technique called Duplicate, Erase, and Replace (DupER) Augmentation through a simulation study. Data are augmented using…

Heuristics embodying limited information search and noncompensatory processing of information can yield robust performance relative to computationally more complex models. One criticism raised against heuristics is the argument that complexity is hidden in the calculation of the cue order used to make predictions. We discuss ways to order cues…

In Ghana, many professional teachers have been leaving teaching to seek employment in jobs that they think hold promise of better pay and prestige. This article critically examines the key factors that compel teachers to leave the teaching profession for other jobs. Thirty professionally trained teachers who had taught at pretertiary institutions…

A concern for generalization dominates quantitative research. For generalizability and repeatability, identification of sample size is essential. The present study investigates 90 qualitative master's theses submitted for the Primary and Secondary School Science and Mathematics Education Departments, Mathematic Education Discipline in 10…

Studies often report that bilingual participants possess a smaller vocabulary in the language of testing than monolinguals, especially in research with children. However, each study is based on a small sample so it is difficult to determine whether the vocabulary difference is due to sampling error. We report the results of an analysis of 1,738…

Monte Carlo simulations are a classical tool to analyse physical systems. When unlikely events are to be simulated, the importance sampling technique is often used instead of Monte Carlo. Importance sampling has some drawbacks when the problem dimensionality is high or when the optimal importance sampling density is complex to obtain. In this…

This study evaluated the effects of an experimenter-delivered choice-making procedure. Three nonambulatory and partially ambulatory preschoolers were given access to six teacher-nominated preferred toys in two conditions: child choice and interventionist choice. Using an alternating treatment design and a 10-second momentary time-sampling…

Background: Researchers have noted difficulties in attracting adequate numbers of participants with intellectual disabilities (ID) to their studies. Methods: This study was a review of participation by adults with ID in research conducted in South Eastern Ontario over a 20-year period (1987-2006). Original research studies were identified by local…

The 2012 National Household Education Surveys Program (NHES:2012) Data File User's Manual provides documentation and guidance for users of the NHES:2012 data files. The manual provides information about the purpose of the study, the sample design, data collection procedures, data processing procedures, response rates, imputation, weighting and…

Anxiety is a psychological factor commonly associated with such feelings as fear, apprehension and uneasiness. It is an individual's affective reaction to a perceived or a real threat (MacIntyre, 1995). Foreign language reading anxiety (FLRA) refers to one's negative attitudes which may, to some extent, account for the inhibition that s/he suffers…

Literacy is an indispensable foundation that enables young people and adults to engage in learning opportunities at all stages of the learning continuum. Literacy is a prerequisite for the development of personal, social, economic and political empowerment. In Nigeria, attempt to increase access to literacy education for the enhancement of…

Recently, the Kenyan government reaffirmed its commitment to enabling majority of its citizen's access to education through establishment of free primary education program and subsidizing secondary education. However, despite all these efforts, the education sector continues to face myriads of problems, major one being skewed performance in Kenya…

This qualitative case study extends the literature on urban district instructional policymaking by analyzing the ways in which normative and political pressures shaped district leaders' instructional policy decisions. Drawing on concepts from the politics of education, it shows how teachers and principals repeatedly nullified policies that aimed…

A college degree is widely accepted as a basic goal in education, and the United States labor market reinforces that expectation with substantial financial rewards. Today, Latinos are enrolling in colleges and universities at astronomical rates. As educators, we must provide this growing student population with the adequate programs and resources…
