This article describes how to construct a laser level. This laser level can be made using a typical 4' (or shorter) bubble level and a small laser point. The laser unit is detachable, so the bubble level can also be used in the conventional way. However, the laser level works better than a simple bubble level. Making this inexpensive device is an…

Background: Investigations of the cognitive processes underlying specific language impairment (SLI) have implicated deficits in the storage and processing of phonological information, but to date these abilities have not been studied in the same group of children with SLI. Aims: To examine the extent to which deficits in immediate verbal…

In this study, kindergarten children's scores on nine cognitive tasks were evaluated as potential predictors of poor achievement in first grade. A set of five tasks successfully identified 83% of children who were poor readers in first grade, while just three tasks identified 72% of children who were poor achievers in math in first grade. There…

Researchers who assume that Universal Grammar (UG) plays a role in second language (L2) acquisition are still debating whether L2 learners have access to UG in its entirety (the Full Access hypothesis; e.g. Schwartz and Sprouse, 1994; 1996; White, 1989; 2003) or only to those aspects of UG that are instantiated in their first language (L1) grammar…

This study examined word identification skills between two groups of college students with different first language (L1) backgrounds (Chinese and Korean) learning to read English as a second language (ESL). Word identification skills were tested in a naming experiment and an auditory category judgment task. Both groups of ESL learners demonstrated…

In the Singlish-"Good" English debate, the use of Singlish (SCE) is viewed as an obstacle to the development of students' literacy skills in standard English (SSE) and so the practice of classroom codeswitching between the two varieties is strongly discouraged. Yet the presence of the vernacular in the classroom continues to be robust.…

Background: Social understanding is often thought to be relatively "protected" in children with Down's syndrome (DS) and to underlie the outgoing personality characteristically attributed to them. This paper draws together findings from our studies of behaviours during object concept testing, generally considered a theoretically "pure" measure of…

This study examined development of pragmatic comprehension ability across time. Twenty native speakers and 92 Japanese college students of English completed a computerized listening task measuring ability to comprehend two types of implied meaning in dialogues: indirect refusals (k = 24) and indirect opinions (k = 24). The participants'…

In general terms automaticity could be defined as the subconscious condition wherein "we perform a complex series of tasks very quickly and efficiently, without having to think about the various components and subcomponents of action involved" (DeKeyser 2001: 125). For language learning, Segalowitz (2003) characterised automaticity as a…

This paper reviews the corpus of research on feedback, with a particular focus on formative feedback--defined as information communicated to the learner that is intended to modify the learner's thinking or behavior for the purpose of improving learning. According to researchers in the area, formative feedback should be multidimensional,…

The aim of this study was to ascertain the nature of the interaction between the affective value of musical distraction, personality type and performance on the cognitive tasks of reading comprehension, free recall, mental arithmetic and verbal reasoning in children aged 11-12 years. It was hypothesized that the cognitive performance of extraverts…

The purpose of this project was to develop a prototype expert instructional design system (ID Expert) which would demonstrate the feasibility of a consultation system for use by inexperienced instructional designers. The prototype gathers information from the designer and then makes recommendations for instructional design decisions. The output of…

This paper discusses obstacles to teaching online documentation and shares a collaborative approach to overcoming these obstacles. The paper describes three obstacles: (1) students have had limited access to online documents and hypertext systems; (2) standards and principles of effective design for online documents are not clearly established;…

This paper discusses two related areas in which recent advancements in cognitive science and educational technology may affect instructional design theory. These are: (1) the analysis of information-to-be-learned; and (2) the linkage of learning theory to instructional prescriptions. The first area proposes extensions to current methods of…

Task analyses are provided for two duty areas for the occupation of medical assistant in the medical assisting cluster. Five tasks for the duty area "providing therapeutic measures" are as follows: assist with dressing change, apply clean dressing, apply elastic bandage, assist physician in therapeutic procedure, and apply topical…
