The Hartung-Knapp method for random-effects meta-analysis, that was also independently proposed by Sidik and Jonkman, is becoming advocated for general use. This method has previously been justified by taking all estimated variances as known and using a different pivotal quantity to the more conventional one when making inferences about the…

We explored relations between reading comprehension performance and self-reported components of metacognition in middle-school children. Students' self-reported metacognitive strategies in planning and evaluation accounted for significant variance in reading comprehension performance on questions involving inferences. In Study 2, middle school…

Null hypothesis testing has long since been the 'go-to analytic approach' in quantitative second language (L2) research (Norris, 2015, p. 97). To many, however, years of reliance on this approach has resulted in a crisis of inference across the social and behavioral sciences (e.g., Rouder et al., 2016). As an alternative to the null hypothesis…

Communication tools have been popular in web-based learning systems because of their ability to promote the interaction and potentially alleviate the high dropout issue. In recent years, with the increased awareness among researchers about the individual difference of the students, more and more personalized learning supports have been developed.…

Does more education lead to less political violence, and may education thus be a tool for peace? This article provides the first systematic review of the existing quantitative literature on education and political violence. Looking at arguments pertaining to levels, expansion, inequality, and content of education, we identify 42 quantitative…

Within psychology and the social sciences, Ordinary Least Squares (OLS) regression is one of the most popular techniques for data analysis. In order to ensure the inferences from the use of this method are appropriate, several assumptions must be satisfied, including the one of constant error variance (i.e. homoskedasticity). Most of the training…

Radical awareness (i.e. the ability to identify, analyze, and manipulate radicals within compound characters) plays an important role in character reading and learning for first language and second language (L2) learners of Chinese. Previous studies have shown that radical awareness contributes to character recognition, inference, and…

This study investigated the effect of visual anthropomorphic stories on students' understanding of the particulate nature of matter and their level of anthropomorphic discourse. This study employed a quasi-experimental research design with pretest and posttest control groups. Science activities supported by visual anthropomorphic stories were…

This study is intended to help English foreign language learners avoid a type of syntactic ambiguity in sentences resulting from prepositional phrases (PPs). The students are guided to make use of the features of both adverbials and adjectivals in resolving this type of ambiguity. The movability of adverbials and the use of relative clauses…

Building on rich training literature, we examined which skills constituting the control-of-variables strategy (CVS) benefit from a comprehensive training, and which develop similarly during content-focused inquiry at ages 10-12. In addition, we examined whether prior knowledge, reasoning abilities, and reading comprehension explain variation in…

This study shows that residual variation can cause problems related to scaling in exponential random graph models (ERGM). Residual variation is likely to exist when there are unmeasured variables in a model--even those uncorrelated with other predictors--or when the logistic form of the model is inappropriate. As a consequence, coefficients cannot…

Research on the use of standardized test scores in higher education reveals significant variations in attitudes and perceptions of language proficiency tests among test score users. Most test score users have limited knowledge about test score interpretations in terms of what English as additional language (EAL) students typically know and can do…

The present study investigated whether parent--child interactions during shared reading in a diverse sample of 91 three- to five-year-old dual language learners (DLLs) in Norway supported the development of the children's first (L1) and second language (L2) vocabulary skills. The dyads spoke 11 different L1s (i.e., Arabic, Polish, Somali, and…

There are grounds for believing that prompting language learners to infer the meaning of new lexical items is beneficial because inferring the meaning of lexical items and verifying one's inferences invites more cognitive investment than simply being presented with the meanings. However, concerns have been raised over the risk that wrong…

Analysis of variance (ANOVA) is a test of "mean" differences, but the reference to "variances" in the name is often overlooked. Classroom activities are presented to illustrate how ANOVA works with emphasis on how to think critically about inferential reasoning.
