The growing popularity of social network sites (SNS) is causing concerns about privacy and security, especially with teenagers, since they show various forms of unsafe behavior on SNS. It has been put forth by researchers, teachers, parents, and teenagers that school is ideally placed to educate teens about risks on SNS and to teach youngsters how…

This qualitative study examines children's comprehension of conventional, wordless, and postmodern picturebooks. The research question was: How do children construct meaning of conventional, wordless, and postmodern picturebooks? More specific questions were: 1) What are the reading strategies that children use as they make sense of…

The purpose of this study is to look closely at how aspects of instructional leadership, and organizational learning affect the quality of madrasah in improving the quality of graduate the state madrasah aliyah. The experiment was conducted using a quantitative approach with descriptive and inferential methods, in inferential methods used…

Science education researchers have long advocated the central role of the nature of science (NOS) for our understanding of scientific literacy. NOS is often interpreted narrowly to refer to a host of epistemological issues associated with the process of science and the limitations of scientific knowledge. Despite its importance, practitioners and…

Research Findings: This study examines the effects of low- and high-cognitive demand discussion on children's story comprehension and identifies contributions of discussion, initial vocabularies, and parent reading involvement. A total of 70 English learner preschoolers took baseline vocabulary tests in Portuguese and English, were randomly…

We surveyed researchers in the health and exercise sciences to explore different areas and magnitudes of bias in researchers' decision making. Participants were presented with scenarios (testing a central hypothesis with p = 0.06 or p = 0.04) in a random order and surveyed about what they would do in each scenario. Participants showed significant…

A consistent body of research shows that large classes have been perceived by teachers as an obstacle to deliver quality teaching. This large-scale study sought to investigate further those differential effects by asking 1,119 teachers from 321 K-12 schools in New South Wales (Australia) their perceptions of ideal class size for a variety of…

There has been a noted growth in the number of teaching assistants (TAs) in mainstream schools. Research is inconclusive about their efficacy at changing outcomes for children and has proposed more training for TAs. Generic training models have suggested that enhancing self-efficacy in turn improves performance. This exploratory study investigated…

This study examined the influence of morphological instruction in an eye-tracking English vocabulary recognition task. Sixty-eight freshmen enrolled in an English course and received either traditional or morphological instruction for learning English vocabulary. The experimental part of the study was conducted over two-hour class periods for…

This paper focuses on an inferential view on introducing new concepts in mathematics classrooms. A theoretical framework is presented which helps to analyse and reflect on the processes of teaching and learning mathematical concepts. The framework is based on the philosophies by Ludwig Wittgenstein and Robert Brandom. Wittgenstein's language-game…

Generalized fiducial inference is a powerful tool for many difficult problems. Based on an extension of R. A. Fisher's work, we used generalized fiducial inference for two extreme value problems and a multiple comparison procedure. The first extreme value problem is dealing with the generalized Pareto distribution. The generalized Pareto…

Following a positively quantified statement such as, "A "few" of the children sang the chorus," a plural pronoun is likely to refer to the set of children who sang (the reference set). Negative natural language quantifiers (NLQs) such as "few" or "not many," on the other hand, are more likely to be followed…

Background: Two kinds of research logic prevail in scientific research: deductive research logic and inductive research logic. However, both fail in the field of evaluation, especially evaluation conducted in unfamiliar environments. Purpose: In this article I wish to suggest the application of a research logic--"abduction"--"the logic of…

Scalar inferences are commonly generated when a speaker uses a weaker expression rather than a stronger alternative, e.g., "John ate some of the apples" implies that he did not eat them all. This article describes a visual-world study investigating how and when perceivers compute these inferences. Participants followed spoken instructions…

According to Adams's Thesis, the acceptability of an indicative conditional sentence goes by the conditional probability of its consequent given its antecedent. We test, for the first time, whether this thesis is descriptively correct and show that it is not; in particular, we show that it yields the wrong predictions for people's judgments of the…
