Statistical studies are referenced in the news every day, so frequently that people are sometimes skeptical of reported results. Often, no matter how large a sample size researchers use in their studies, people believe that the sample size is too small to make broad generalizations. The tasks presented in this article use simulations of repeated…

Errors in detecting randomness are often explained in terms of biases and misconceptions. We propose and provide evidence for an account that characterizes the contribution of the inherent statistical difficulty of the task. Our account is based on a Bayesian statistical analysis, focusing on the fact that a random process is a special case of…

There is a general agreement that critical thinking is an important element of 21st century skills. Although critical thinking is a very complex and controversial conception, many would accept that recognition and evaluation of assumptions is a basic critical-thinking process. When students use simple mathematical model to reason quantitatively…

This study examined transfer facilitation effect of first language morphological awareness on second language lexical inference ability among Grade 6 Chinese-speaking English as a foreign language learners in China. A set of paper and pencil tests was administered to measure children's morphological awareness and lexical inference ability in both…

Teachers can engage students in historical thinking by intentionally structuring close reading tasks. This article provides a practical and theoretical examination of the learning and teaching during a 30-minute social studies class in which students studied colonization by reading a primary source text from the Jamestown Colony. Students used…

In the domain of discourse processing, it has been claimed that older adults (60-0-year-olds) are less likely to encode and remember some kinds of information from texts than young adults. The experiment described here shows that they do make a particular kind of inference to the same extent that college-age adults do. The inferences examined were…

This article examines the estimation of two-stage clustered designs for education randomized control trials (RCTs) using the nonparametric Neyman causal inference framework that underlies experiments. The key distinction between the considered causal models is whether potential treatment and control group outcomes are considered to be fixed for…

Can students be taught to better comprehend the diagrams in their textbooks? Can such teaching transfer to uninstructed diagrams in the same domain or even in a new domain? What methods work best for these goals? Building on previous research showing positive results compared to control groups in both laboratory studies and short-term…

There is an increasing emphasis on evidence-based education, and the sciences of learning are progressing rapidly. But are reports, guidelines, and outreach enough to disseminate this knowledge and affect educational practice? In fact, policy makers and the public often resist evidence-based recommendations about education. This article suggests…

Human social interaction depends on individuals identifying the common ground they have with others, based both on personally shared experiences and on cultural common ground that all members of the group share. We introduced 3- and 5-year-old children to a culturally well-known object and a novel object. An experimenter then entered and asked,…

Synthetic control methods are an innovative matching technique first introduced within the economics and political science literature that have begun to find application in educational research as well. Synthetic controls create an aggregate-level, time-series comparison for a single treated unit of interest for causal inference with observational…

Existing studies of source use in academic student writing tend to i), focus more on the writing than the reading end of the reading-to-write continuum and ii), involve the use of insufficiently "naturalistic" writing tasks. Thus, in order to explore the potential of an alternative approach, this paper describes an exploratory case study…

The focus of this research-based review is how to best develop and manage online classes. After receiving faculty, student, and industry feedback, Colorado State University-Global Campus integrated multi-perspective design teams to develop and manage multilayered online courses. This article will reveal the instructional design, development…

The present article examines the outcomes derived from a task on intensive reading carried out by university students. The main goal is to analyze the frequency of use and the success of idiom solving strategies used by the subjects while reading. Additionally, our interest is to compare the above outcomes and the reading time scores of a group of…

The primary aim of this study was to investigate whether and, if so, how formal teacher competence relates to the relationship between pupil reading achievement and teachers judgements' of pupils' reading achievement. The data come from the Swedish participation in the Progress in International Reading Literacy Study (PIRLS) 2001 in Grade 3.…
