A recent graphic schemas account of drawing development that emphasizes the appropriation of graphic conventions has provided an alternative to constructivist theories, which have viewed development as a progression through universal stages. The present study addresses the limitations of this account by investigating younger children than have…

To set an optimal decision criterion on a test of recognition, a subject must estimate the degree to which they can discriminate previously studied from unstudied stimuli. To do so accurately, the subject must assess not only their mastery of the material but also the extent to which the distractors yield mnemonic evidence that makes them…

In the past few years researchers have begun to show an interest in humour and language play as it relates to second language learning (SLL). Tarone (2000) has suggested that L2 language play may be facilitative of SLL, in particular by developing sociolinguistic competence, as learners experiment with L2 voices; and by destabilizing the…

Awareness of structures may be conscious or unconscious in the expert user of a language: this paper contends that insufficient conscious awareness of a language structure in teachers of English may impair the teaching and learning of that structure, even when considerable classroom time is invested in it. Phrasal verbs are extensively covered in…

Singapore has many large and educationally valuable digital collections and is planning the development of many more. These digital collections contain historical, cultural and scientific multimedia objects, along with learning objects. At present, school teachers and pupils find it hard to locate many of these resources using traditional search…

In this paper, we describe concept parsing algorithms, a novel semantic analysis methodology at the core of a new pedagogy that focuses learners attention on deep comprehension of the conceptual content of learned material. Two new e-learning tools are described in some detail: interactive concept discovery learning and meaning equivalence…

In the present study, a semantic perspective on e-learning theory is advanced and a modelling approach is used. This modelling approach towards the new learning theory is based on the four SECI phases of knowledge conversion: Socialisation, Externalisation, Combination and Internalisation, introduced by Nonaka in 1994, and involving two levels of…

It is widely attested that university students face considerable difficulties with reasoning in analysis, especially when dealing with statements involving two different quantifiers. We focus in this paper on a specific mistake which appears in proofs where one applies twice or more a statement of the kind "for all X, there exists Y such that R(X,…

Genres embody typified discursive activity that is situated in an ecology of texts, people, and tools. Within these settings, genres help writers compose recognizable information artifacts. Increasingly, however, many professions are becoming mobile, and mobile technologies (e.g., personal digital assistants [PDAs]) are creating problems of…

Background: Verbal intrusion errors are irrelevant responses made in the course of verbal memory retrieval or language production that have been associated with disruption of executive functions and the prefrontal cortex. They have been observed to occur more frequently both with normal aging and with neurodegenerative diseases such as Alzheimer's…

It is acknowledged that contrast plays an important role in understanding discourse and information structure. While it is commonly assumed that contrast can be marked by intonation only, our understanding of the intonational realization of contrast is limited. For German there is mainly introspective evidence that the rising theme accent (or…

It is a matter of debate whether the two differentiated grammatical systems in a bilingual child develop autonomously, or whether there is interdependence and in what areas (Genesee, 2001; Meisel, 2001). Extensive research is being carried out in the emergence of the two grammars, but not much attention has been given to the development of…

Three experiments investigated the ability of eight-year old children with poor language comprehension to produce past tense forms of verbs. Twenty children selected as poor comprehenders were compared to 20 age-matched control children. Although the poor comprehenders performed less well than controls on a range of tasks considered to tap…

This study was designed to explore a model of communicative competence (Abbeduto & Nuccio, 1989) and identify whether its components could (a) predict pragmatic language difficulties for children with emotional or behavioral disorders (E/BD) and (b) describe the semantic, syntactic, and pragmatic language ability as well as the social skills of…

Statistical thinking is required for good statistical analysis. Among other things, statistical thinking involves identifying sources of variation. Students in introductory statistics courses seldom recognize that one of the largest sources of variation may come in the collection and recording of the data. This paper presents some simple exercises…
