We performed a meta-analysis of dual-task experiments to assess the robustness of the effects of conducting working memory secondary tasks on arithmetic performance. Four hundred effect sizes from 21 studies from 1,049 participants were analyzed across a variety of specifications. Results revealed that increases in working memory load resulted in…

The involvement load hypothesis (ILH) was designed to predict the effectiveness of instructional tasks for incidental L2 vocabulary learning. In this meta-analysis we examined 398 effect sizes from 42 empirical studies (N = 4,628) to explore (a) the overall predictive ability of the ILH, (b) the relative effects of different components of the ILH…

Purpose: Despite the apparent primacy of syntactic deficits, children with developmental language disorder (DLD) often also evidence lexical impairments. In particular, it has been argued that this population have difficulty forming lexical representations that are detailed enough to support effective spoken word processing. In order to better…

e-Portfolios have become increasingly popular among educators as learning tools. Some research even shows that e-portfolios can be utilised to facilitate the development of skills for self-directed learning. Such skills include self-assessment of performance, formulation of learning goals, and selection of future tasks. However, it is not yet…

Autism is currently one of the most prominent and widely discussed human conditions. Its increased prevalence has intensified the demand for effective educational and therapeutic services, and intervention science is providing mounting evidence about practices that positively impact outcomes. The purpose of this report is to describe a set of…

We reviewed twelve studies that used the constant time delay (CTD) procedure to teach chained tasks to individuals with developmental disabilities from years 1996-2006. Variables analyzed include types of tasks that have been taught with the procedure, how effective CTD has been in teaching participants, and whether researchers have investigated…

The authors review recreation/leisure training programs conducted with moderately/severely disabled individuals. Emphasis is placed on databased task-analytic, instructional efforts and recent curriculum volumes/position papers. Programing implications include the value of task sequences involving gradual increments in response requirements.…

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,…

Discusses three major areas in which cognitive psychology and educational technology are affecting instructional design (ID) theory: (1) analysis of information, including content analysis and task analysis; (2) the means of evaluating learners; and (3) linking learning theory with specific instructional strategies through an integrated…

Presents an overview of time study research in school library media centers that attempts to categorize the tasks performed by school library media specialists and the time devoted to them. Suggests implications for preservice and continuing education, salaries, and the need for future time studies. (Author/LRW)

Four papers from the University of California at San Diego (UCSD) Project on Human-Computer Interfaces are presented in this report. "Evaluation and Analysis of User's Activity Organization," by Liam Bannon, Allen Cypher, Steven Greenspan, and Melissa Monty, analyzes the activities performed by users of computer systems, develops a…

The purpose of this literature review was to determine what evidence there is that instructional designers apply ID Models, as well as to establish what other activities and processes they might use in their professional activities. Only ten articles were located that directly pertained to this topic: seven reporting on empirical research and…

A review of 20 research studies on the use of constant time delay in teaching chained tasks is analyzed in regard to demographic variables (participants, settings), procedural variables (probe format, delay sessions), outcome measures (effectiveness, generalization), and methodological adequacy (dependent and independent variable reliability).

Fifty-five recent studies of individual differences (IDs) in elementary cognitive tasks (ECTs) are reviewed. Twenty-five data sets are examined, analyzed, or reanalyzed by factor analysis. The following promising dimensions are identified: basic perceptual processes, reaction and movement times, mental comparison and recognition tasks, retrieval…
