Rapid growth in nanoscience and nanotechnology in recent years has been accompanied by studies of the toxicity and potential impacts of nanomaterials on human health and the environment, but less has been done concerning education in this area. There is therefore a need for courses that address this theme at universities worldwide, in order to…

Diagnostic classification models (DCMs) hold great potential for applications in summative and formative assessment by providing discrete multivariate proficiency scores that yield statistically driven classifications of students. Using data from a newly developed diagnostic arithmetic assessment that was administered to 2032 fourth-grade students…

In the debate on the integration of information and communication technologies (ICT) into schools, the beliefs and attitudes of teachers towards ICT in teaching and learning have always been regarded as central criteria for successful implementation of new technologies. In this context, a study in 2013 by the International Association for the…

This paper presents an investigation of verb morphology in the spontaneous productions of three preschool Egyptian Arabic- (EA) speaking children with language impairment (LI) and a group of typically developing children. The typological characteristics of Arabic, such as its rich morphology, lack of infinitival form and complex verb system, make…

This paper reports an investigation into whether a test of productive vocabulary size using a category generation task can be useful and effective. A category generation task is a simple task where learners are asked to name as many as words as they can from a prescribed category such as "animals" or "body" parts. The virtue of…

This dissertation explores the way Kotiria/Wanano (E. Tukanoan, Kotiria hereafter) women of the Brazilian "Alto Rio Negro" (ARN) contrive (McDowell 1990) "kaya basa" "sad songs" using linguistic and musical resources to construct songs that express loneliness and other private emotions, while also creating alliances…

Producing a sensible utterance requires speakers to select conceptual content, lexical items, and syntactic structures almost instantaneously during speech planning. Each language offers its speakers flexibility in the selection of lexical and syntactic options to talk about the same scenarios involving movement. Languages also vary typologically…

Learning disabilities are conditions that are associated with difficulties in knowledge and skill acquisition to the level expected of same-age peers. The current book is an international examination of assessment methods, preventative measures, intervention, and research with those individuals with learning disabilities obtained from authors in…

Since MOOC is suffering high dropout rate, researchers try to explore the reasons and mitigate it. Focusing on this task, we employ a composite model to infer behaviors of learners in the coming weeks based on his/her history log of learning activities, including interaction with video lectures, participation in discussion forum, and performance…

The current study aims to determine science student teachers' cognitive structure on the concept of food chain. Qualitative research method was applied in this study. Fallacies detected in the pre-service teachers' conceptual structures are believed to result in students' developing misconceptions in their future classes and will adversely affect…

Attention allocation in word learning may vary developmentally based on the novelty of the object. It has been suggested that children differentially learn verbs based on the novelty of the agent, but adults do not because they automatically infer the object's category and thus treat it like a familiar object. The current research examined…

This article draws on ethnographic research that examines the contemporary articulation of class identity in the postcolonial elite school setting of Old College high school in Barbados. From the qualitative data derived from this study, we argue that social class is better conceived as a series of flows, mutations, performances and performatives.…

In order to trace how mobile assisted language learning (MALL) has evolved in recent years, we analysed studies published from 2000 to 2012 to examine their characteristics and research trends. These studies were published in international journals listed in the Social Sciences Citation Index (SSCI). Sixty-nine studies that fit the time frame and…

Reusable educational resources became increasingly important for enhancing learning and teaching experiences, particularly in the medical domain where resources are particularly expensive to produce. While interoperability across educational resources metadata repositories is yet limited to the heterogeneity of metadata standards and interface…

Purpose: Our purpose was to study strategy use during nonlinguistic category learning in aphasia. Method: Twelve control participants without aphasia and 53 participants with aphasia (PWA) completed a computerized feedback-based category learning task consisting of training and testing phases. Accuracy rates of categorization in testing phases…
