Meta-analyses of clinical trials targeting rare events face particular challenges when the data lack adequate numbers of events for all treatment arms. Especially when the number of studies is low, standard random-effects meta-analysis methods can lead to serious distortions because of such data sparsity. To overcome this, we suggest the use of…

Direct observation recording procedures produce reductive summary measurements of an underlying stream of behavior. Previous methodological studies of these recording procedures have employed simulation methods for generating random behavior streams, many of which amount to special cases of a statistical model known as the alternating renewal…

This paper presents the results of a systematic review of agent-based modelling and simulation (ABMS) applications in the higher education (HE) domain. Agent-based modelling is a "bottom-up" modelling paradigm in which system-level behaviour (macro) is modelled through the behaviour of individual local-level agent interactions (micro).…

Computers in non-school settings, educational computer games, and education without schools are the primary topics covered in this three-section paper. The first section describes the use of personal computers in two different, non-school environments: the home and computer clubs. A "diary study" by Yaakov Kareev is summarized, in which…

Discussion of communication between designers and users of information systems focuses on a review of seven participatory design techniques in terms of the communication dimensions found in the Lievrouw and Finn communication systems model. Implications for the development of more effective and appropriate design models and methods are suggested.…

Reviews concepts which form the basis for a communicative approach to foreign language software design. Examples of communicative program formats, the role of Local Area Networks, and teachers' roles in designing and implementing such software are also discussed. (Author/CB)

Highlights include computers, children, and research; social and emotional development; types of software; motivation; social and cognitive interactions; cognitive development; creativity; language and literacy; writing and word processing; mathematics and reasoning; and science and…

Significant advances in hardware and software have increased the possible applications for educating limited-English-proficient students. Two major studies have focused on technology and its relationship to the education of this population. There is a great diversity of hardware currently in use in schools, either stand-alone computers or computer…
