The purposes of the current study are to develop virtually immersive EFL learning contexts for EFL learners in Taiwan to pre- and review English materials beyond the regular English class schedule. A 2-iteration action research lasting for one semester was conducted to evaluate the effects of virtual contexts on learners' EFL learning. 132…

With the advances in technology, wordlists retrieved from computer corpora have become increasingly popular in recent years. The lexical items in those wordlists are usually selected, according to a set of robust frequency and dispersion criteria, from large corpora of authentic and naturally occurring language. Corpus wordlists are of great value…

Automatic Speech Recognition (ASR) technology has become a part of contemporary Computer-Assisted Language Learning (CALL) systems. ASR systems however are being criticized for their erroneous performance especially when utilized as a mean to develop skills in a Second Language (L2) where errors are not tolerated. Nevertheless, these errors can…

This paper reports on an exploratory case study of learner participation within the context of online language learning in virtual world platforms. Data for this investigation was collected through a case study of a Business English course within a qualitative Case-Study Research framework. This study examines learner activity in virtual worlds in…

Archived transcripts from tens of millions of online human tutoring sessions potentially contain important knowledge about how online tutors help, or fail to help, students learn. However, without ways of automatically analyzing these large corpora, any knowledge in this data will remain buried. One way to approach this issue is to train an…

In this study we examine the use of cumulative and exploratory talk types in a year 5 computer supported collaborative learning environment. The focus for students in this environment was to participate in mathematical problem solving, with the intention of developing the proficiencies of problem solving and reasoning. Findings suggest that…

The current study examined how components of reflective practice interplay with children's music-making and sharing processes. This study employed a qualitative approach with 11 children who played classroom instruments and researcher-designed computer programs ("Build MyTune I" and "Build MyTune II") while attending music…

Across three papers I study how differences in the quality and quantity of classroom instruction contribute to differences in what students learn in school. The first two papers focus on teachers--specifically what gives rise to differences between teachers in student learning. The third paper focuses on the quantity of instruction time students…

The heterogeneous equilibrium of the solubility of calcium hydroxide in water is used to predict both its solubility product from solubility and solubility values from solubility product when inert salts, in any concentration, are present. Accepting the necessity of including activity coefficients to treat the saturated solution of calcium…

We propose an articulated computational experiment in which both quantum mechanics (QM) and molecular mechanics (MM) methods are employed to investigate environment effects on the free energy surface for the backbone dihedral angles rotation of the small dipeptide N-Acetyl-N'-methyl-L-alanylamide. This computation exercise is appropriate for an…

Comprehension is the essence of reading. Finding appropriate and effective reading strategies to support students' reading comprehension has always been a critical issue for educators. This article presents findings from a meta-analysis of 17 studies of metacognitive strategy instruction on students' reading comprehension in computerized…

This study aims to investigate (1) methods utilized in mobile computer-supported collaborative learning (mCSCL) research which focuses on studying, learning and collaboration mediated by mobile devices; (2) whether these methods have examined mCSCL effectively; (3) when the methods are administered; and (4) what methodological issues exist in…

This study investigated the effect of different methods of guidance with anchored instruction on students' mathematical problem-solving performance. The purpose of this research was to iteratively design a learning environment to find the optimal level of guidance. Two iterations of the software were compared. The first iteration used explicit…

This research was commissioned by CfBT Education Trust and carried out in conjunction with the Institute for the Future of the Mind at the University of Oxford. The project sought to establish whether teaching pupils about the brain could impact upon their beliefs about their own intelligence (amongst other motivational measures) and ultimately…

If teachers of Less-Commonly Taught Languages (LCTLs), such as Irish, are to make use of Open Educational Resources (OERs) and many other CALL tools, then there must be an appropriate adaptation of the Common European Framework of Reference (CEFR) in that LCTL. The need to be "Bologna-compliant" has seen language courses and syllabuses…
