This study employs a meta-analysis of single-subject design research to investigate the efficacy of mobile device-based interventions for individuals with intellectual disabilities (ID) and to further examine possible variables that may moderate the intervention outcomes. A total of 23 studies, 78 participants, and 140 observed cases that met the…

This study adopted Ambridge's research paradigm to examine the effects of entrenchment, preemption, and verb semantics in second language (L2) acquisition of English "un-" prefixation. Three groups of Chinese learners of English (second- and fourth-year English majors and teachers of English) rated the acceptability of 48 "un-"…

Without a science background as sophisticated as that of a scientist, the evaluation of science in the media has proved to be a challenge to members of the public who are largely non-specialists. It is generally assumed that understandings of nature of science (NOS) will lead to this desired outcome of scientific literacy. This study examined the…

Internationally, efforts are being made for educational practice to be research-informed on the grounds that schoolteachers will implement what research shows will "work". However, teachers do not necessarily accept research findings; sometimes they contest them. This article considers teachers' contestation in two empirical studies,…

This dissertation examines the question of how phonological alternations are learnt. In constraint-based models of phonological learning, it is hypothesized that prior learning of phonotactics from the lexicon facilitates the learning of alternations. While this is an influential assumption, the empirical evidence for it is equivocal. In this…

The topic of this study was the way teachers of children with autism perceive the home-school collaboration and its impact on learning. This research addressed the gap in the literature on the topics of children with autism's performance gap in comparison to their age-equivalent peers. The research question was, "How do teachers of children…

Biased sampling occurs frequently in economics, epidemiology, and medical studies either by design or due to data collecting mechanism. Failing to take into account the sampling bias usually leads to incorrect inference. We propose a unified estimation procedure and a computationally fast resampling method to make statistical inference for…

Double-entry bookkeeping (DEB) implicitly uses a specific mathematical construction, the group of differences using pairs of unsigned numbers ("T-accounts"). That construction was only formulated abstractly in mathematics in the nineteenth century, even though DEB had been used in the business world for over five centuries. Yet the…

Context: Generalization is a critical concept in all research designed to generate knowledge that applies to all elements of a unit (population) while studying only a subset of these elements (sample). Commonly applied criteria for generalizing focus on experimental design or representativeness of samples of the population of units. The criteria…

The author of this commentary argues that physical scientists are attempting to advance knowledge in the so-called hard sciences, whereas education researchers are laboring to increase knowledge and understanding in an "extremely hard" but softer domain. Drawing on the work of Popper and Dewey, this commentary highlights the relative…

Sleep enhances generalization in adults, but this has not been examined in toddlers. This study examined the impact of napping versus wakefulness on the generalization of word learning in toddlers when the contextual background changes during learning. Thirty 2.5-year-old children (M = 32.94, SE = 0.46) learned labels for novel categories of…

With one treated and one untreated periods, difference in differences (DD) requires the untreated response changes to be the same across the treatment and control groups, if the treatment were withheld contrary to the fact. A natural way to check the condition is to backtrack one period and examine the response changes in two pretreatment periods.…

Student attitudes toward mathematics play an important role in the teaching and learning processes of mathematics as positive attitudes correlate with higher student achievement. This paper aims to develop and explore the validity of a Chinese version of the short attitudes toward mathematics inventory (short ATMI) for Taiwanese undergraduates,…

Dressing skill is one of the necessary self-care skills that is taught to individuals with autism in order for them to be able to live independently. Typically, developing individuals can acquire dressing skill on their own; however, children with autism have difficulties in learning such skill without systematic teaching. Thus, teaching dressing…

A recent study of the psychological type profile of Christian youth workers in the UK drew attention to differences between the profiles of youth workers and clergy, and highlighted distinctive strengths and weaknesses that may be experienced by youth workers in Christian ministry. The present study, employing the Francis Psychological Type Scales…
