Nonverbal behavior is essential in human interaction (Gullberg, de Bot, & Volterra, 2008; McNeill, 1992, 2005). For second language speakers, nonverbal features can be helpful for successful and efficient communication (e.g., Dahl & Ludvigsen, 2014). However, due to the complexity of nonverbal features, language testing institutions have…

In-class activities that use a collaborative learning approach were developed for a one-semester biochemistry course as a way to achieve higher student engagement. The redesign of this course from a traditional lecture to a format that incorporated a significant active learning component without reducing the amount of content is described. These…

Cooperative learning is considered to be effective to enhance students' English skills. This study utilizes two learning models under cooperative learning: Ing Ngarsa Sung Tuladha and Student Teams Achievement Division (STAD). This study aims to find out whether there is a significant difference between those two learning models in enhancing…

Naturalistic polyadic family conflicts (i.e., involving three or more members) were studied over a 2-year period by comparing disputes originating between siblings (sibling-originated) or a parent and child (parent-child-originated). Conflicts were coded for (a) origination, (b) topic, (c) resolution, and (d) power in 39 families with two children…

Quality assurance strategies and standards have long been employed--at least since the dawn of the industrial age, which introduced mass operations and mass production to meet the needs of consumers. In any workplace, plans and strategies are systematically devised and guidelines are implemented in order to ensure the conformity of operations and…

Launching biomedical innovations based on clinical demands instead of translating basic research findings to practice reduces the risk that the results will not fit the clinical routine. To realize this type of innovation, a meta-analysis of the body of research is necessary to reveal demand-matching concepts. However, both the data deluge and the…

Previous studies have shown self-criticism to be negatively associated with goal progress. In order to investigate factors that may influence this association, the present study examined the interactive impact of performance (failure vs. success) and self-criticism on working memory (WM). Goal-directed behavior in the achievement domain was…

According to the seductive detail effect, adding interesting but irrelevant information (i.e., seductive details) can be detrimental to learning success. In this study, it was explored within two experiments whether the valence of text-based seductive details might affect learning outcomes differently. For Experiments 1 and 2, we pretested…

Learning analytics research has used both knowledge engineering and machine learning methods to model student behaviors within the context of digital learning environments. In this paper, we compare these two approaches, as well as a hybrid approach combining the two types of methods. We illustrate the strengths of each approach in the context of…

Mathematics learning standards across the United States include conceptual knowledge of numbers and use of modeling and explanation within computation. The concrete-representational-abstract (CRA) sequence and the Strategic Instruction Model (SIM) have been shown to be effective in increasing students' fluency in computation, including…

Purpose: This study investigated the effects of signs on word learning by children with developmental language disorder (DLD), in comparison with typically developing (TD) children, and the relation between a possible sign effect and children's linguistic and cognitive abilities. Method: Nine- to 11-year-old children with DLD (n = 40) and TD…

E-learning enables learners to learn everywhere and at any time but this kind of learning lacks the necessary attractiveness. Therefore, adaptation is becoming increasingly important and the recent research interest in the adaptive e-learning system. Since emotions and personality are important parts of human characteristics, and they play a…

Purpose: Prior investigations suggest that simultaneous performance of more than 1 motor-oriented task may exacerbate speech motor deficits in individuals with Parkinson disease (PD). The purpose of the current investigation was to examine the extent to which performing a low-demand manual task affected the connected speech in individuals with and…

In item response theory (IRT) modeling, the Fisher information matrix is used for numerous inferential procedures such as estimating parameter standard errors, constructing test statistics, and facilitating test scoring. In principal, these procedures may be carried out using either the expected information or the observed information. However, in…

In Portugal, research productivity is nowadays essential for the positive assessment of academics, research units and study programmes. Academic inbreeding has been highlighted in the literature as one of the factors influencing research productivity. This paper tests the hypothesis that inbreeding is detrimental for research productivity,…
