The aim of this study is to examine the pre-service teachers' pedagogical content knowledge about the subject of circle in the context of knowing the source of students' mistakes and offering correct solutions. The participants of the study consisted of 30 pre-service teachers who were studying in the last grade of Department of Mathematics…

Mobile phone technology is becoming ubiquitous. However, a number of unique usability challenges are still unresolved, including small screen size, device orientation changes, and an array of interaction methods (tap, flick, pinch, etc.) These challenges may be particularly acute for people with learning disabilities. This study examined the…

A body of previous work in second- and foreign language pronunciation instruction (e.g., Lord, 2005; Miller, 2012) has shown that explicit phonetic and pronunciation instruction is beneficial. However, Olson (2014) noted that just a few minutes per week of instruction are devoted to pronunciation in most classrooms. What is the effect of such…

Purpose: This study examines the response patterns of 278 Spanish-English dual language learners (DLLs) on a standardized test of receptive English vocabulary. Method: Investigators analyzed responses to 131 items on the Peabody Picture Vocabulary Test--Fourth Edition (Dunn & Dunn, 2007) focusing on differential accuracy on items influenced by…

On the evidence of four lexical-decision tasks in German, we examine speakers' sensitivity to internal morphological composition and abstract morphological rules during the processing of derived words, real and novel. In a lexical-decision task with delayed priming, speakers were presented with two-step derived nouns such as "Heilung…

Researchers and instructors have only recently embraced the role of errors as vehicles for learning in the algebra classroom. Studying a mixture of correct and incorrect worked examples has been shown to be beneficial relative to correct worked examples alone. This study examines the effectiveness of having students generate, or anticipate, errors…

This study aimed at the analysis of syntactic errors in translation done by both bilingual and monolingual EFL learners. Research on the subject of the study implied that there might be differences between monolinguals and bilingual learners of foreign languages. The gaps of studies on differences between monolinguals and bilingual's translations…

Mixed-attainment mathematics teaching is not a common practice in England, despite evidence that ability grouping is not an effective strategy for improving educational outcomes. This study compares mathematics in School M (mixed-ability groupings) and School S (sets) in relation to student beliefs, and teacher beliefs and practices. Questionnaire…

Purpose: Using a blocked cyclic picture-naming task, we compared accuracy and error patterns across languages for Spanish-English bilingual children with and without developmental language disorder (DLD). Method: Pictured stimuli were manipulated for semantic similarity across two (Same and Mixed) category contexts. Children's productions were…

This study examines the effects of asymmetrical mappings of L2 sounds to L1 sounds on real-time processing of L2 phonology. L1-Korean participants completed a self-paced listening (SPL) task paired with a picture verification (PV) task, in which an English sentence was presented word by word along with a picture that matched or mismatched the…

The International Association for the Evaluation of Educational Achievement (IEA) Research for Education series represents a further effort by IEA to capitalize on it's unique datasets, so as to provide powerful information for policymakers and researchers. Each report focuses on a specific topic and is produced by a dedicated team of leading…

This article studies students' use of sentence variety in an ESL writing course. The study includes three sentence features: (a) sentence types, (b) sentence combining, and (c) sentence patterns. Although sentence variety is part of the curriculum, the actual use of sentence structures has not been measured so far. By understanding students' use…

Our study examines written corrective feedback generated by two online grammar checkers (GCs), Grammarly and Virtual Writing Tutor, and by the grammar checking function of Microsoft Word. We tested the technology on a wide range of grammatical error types from two sources: a set of authentic ESL compositions and a series of simple sentences we…

To enable children to develop towards becoming part of the solution to environmental problems, it is essential that they are given the opportunity to become familiar with the natural world from early childhood. Familiarity is required to develop understanding of, care for and, ultimately, action in terms of protecting the natural world. As…

The aim of this study is to reveal the feedback that secondary school science teachers provide for the student errors that show up during their lessons. Six different science teachers were observed throughout 90 sessions of science lessons for sixth and seventh grade in six different units as unstructured with this aim. The case study method was…
