Low frequency Repetitive Transcranial Magnetic Stimulation (rTMS) has previously been applied to language homologues in non-fluent populations of persons with aphasia yielding significant improvements in behavioral language function up to 43 months post stimulation. The present study aimed to investigate the electrophysiological correlates…

Learning mathematics is a complex and dynamic process. In this paper, the authors adopt a semiotic framework (Yeh & Nason, 2004) and highlight programming as one of the main aspects of the semiosis or meaning-making for the learning of mathematics. During a 10- week teaching experiment, mathematical meaning-making was enriched when primary…

Classroom discussions of multimodal texts, in particular historical fiction picturebooks, offer an interpretive space where readers are positioned to construct meanings in transaction with the written language, visual images, and design elements created by authors, illustrators and publishers (Serafini & Ladd, 2008; Sipe, 1999). This study was…

Citizenship is not a neutral word; it evokes numerous interpretations and connotations in various policies, discourse, and practices. Its significance is motivated by current narratives of rights and responsibilities of a citizenry, (illegal) immigration, and English-only ideologies. The basis for this investigation is the perception that the U.S.…

In this dissertation, I address the ways in which food manufacturers can exploit the often vague and ambiguous nature of FDA policies concerning language and images used on food labels. Employing qualitative analysis methods (Strauss, 1987; Denzin and Lincoln, 2003; Mackey and Gass, 2005) that drew upon critical discourse analysis (Fairclough,…

Educators can think of changes in the international literacy landscape as a powerful wave. In this report, the authors argue that given the changes affecting classrooms through information and communications technology, and increasing student diversity not only do they want to prepare for the wave, but they wish to harness its power. This…

This qualitative study focused on the use of multiliteracies (reading, writing, viewing, visually representing, talking, and listening) by four low-income African American LBT (lesbian, bisexual, transgender) adolescents in an out-of-school setting. Data collection methods over a three-month period included transcribed field notes, interviews,…

Colour, a visual element of art and design, is a semiotic mode that is used strategically by sign-makers to communicate meaning. Understanding the meaning-making potential of colour can enhance students' understanding, appreciation, interpretation and composition of multimodal texts. This article features a case study of Anya, an 11-year-old…

Previous studies have found a late frontal-central audiovisual interaction during the time period about 150-220 ms post-stimulus. However, it is unclear to which process is this audiovisual interaction related: to processing of acoustical features or to classification of stimuli? To investigate this question, event-related potentials were recorded…

Do humans search in memory using dynamic local-to-global search strategies similar to those that animals use to forage between patches in space? If so, do their dynamic memory search policies correspond to optimal foraging strategies seen for spatial foraging? Results from a number of fields suggest these possibilities, including the shared…

Many studies have shown that the visual cortex of blind humans is activated in non-visual tasks. However, the electrophysiological signals underlying this cross-modal plasticity are largely unknown. Here, we characterize the neuronal population activity in the visual and auditory cortex of congenitally blind humans and sighted controls in a…

This article argues for the adoption of a new language in critical educational studies through the "narrative turn", a turn that politicizes knowledge by drawing attention to questions concerning the meaning, construction and authorship of narratives. In the authors' interpretation going back to the poetics of early narrative forms they…

Retrieval-induced forgetting (RIF) is a widely studied phenomenon of human memory, but RIF of arithmetic facts remains relatively unexplored. In 2 experiments, we investigated RIF of simple addition facts (2 + 3 = 5) from practice of their multiplication counterparts (2 x 3 = 6). In both experiments, robust RIF expressed in response times occurred…

The effect of test-induced priming on false recognition was investigated in children aged 5, 7, 9, and 11 years using lists of semantic associates, category exemplars, and phonological associates. In line with effects previously observed in adults, nine- and eleven-year-olds showed increased levels of false recognition when critical lures were…

Higher education institutions are increasingly interested in offering more flexible teaching and learning delivery methods that are often independent of place. Where foreign language learning is concerned, telecollaboration is gaining ground. This paper focuses on synchronous webconferencing-supported teaching and examines how different semiotic…
