Teachers of students with learning disabilities (LD) who also are emergent bilingual (EB) are tasked with meeting students' individual learning needs and developing academic language. Teachers require specialized knowledge in second-language acquisition and the specific learning strategies to support students' learning disabilities. Reading…

This article examines the superficial and deep ethical and moral dilemmas confronting "insider" researchers, which we term external and internal ethical engagement. External ethical engagement refers to the traditional, easily identifiable ethical issues that insider researchers attend to by submitting their application for ethical approval to…

An experiment compared asynchronous versus synchronous instruction in an online quantitative course. Mann-Whitney U-tests, correlation, analysis of variance, t tests, and multivariate analysis of covariance (MANCOVA) were utilized to test the hypothesis that more high-quality online experiential learning interactions would increase grade.…

In the past two decades, the role of language in the science curriculum has become prominent in science education literature. From a constructivist perspective, language mediates social interaction and meaning is constructed as learners interpret and reinterpret events through the lens of prior knowledge. This perspective applied to the science…

Open educational resources (OERs) are designed to be globally reusable. Yet comparatively little attention has been given to the cultural issues. This paper addresses the issue of culturally sensitive factors that may influence the design of reusable learning objects. These influences are often subtle and hard to manage. The paper proposes a…

Contrary to system-controlled multimedia learning environments, hypermedia systems are characterized by a high level of interactivity. This interactivity is referred to as learner control in the respective literature. For several reasons this learner control is seen as a major advantage of hypermedia for learning and instruction. For instance,…

Abduction is a method of reasoning that people use under uncertainty in a context in order to come up with new ideas. The use of abduction in this exploratory study is twofold: (i) abduction is a cross-disciplinary analytic tool that can be used to explain certain key aspects of human-computer interaction in advanced Information Society Technology…

How do groups of 3 people establish common ground in problem-solving interactions differently from groups of 2? Do they do this differently when they are supported by videoconferencing technologies? The laboratory experiment reported here manipulated group size and video mediation for participants carrying out a laboratory map task that allowed…

The facilitative effect of expertise in hypertext information retrieval (IR) tasks has been widely reported in related literature. However, recent theories of human expertise question the robustness of this result, since previous works have not fully considered the interaction between user and system characteristics. In this study, the constraint…

Learning is an active process, and, as such, interactive lectures are considered as the educational best practice. This study investigated the efficacy of interactive lecturing in a module of eight respiratory physiology lectures in a second-year Physiology course with two distinct subcohorts: students with strong science backgrounds and those…

Discusses results of an evaluation of a Web-based course at the United Kingdom's Open University relating to student satisfaction. Considers skills versus academic content, previous computing experience, interaction through computer conferencing, online group work, online tutoring, lack of time, and course revision; and compares results with three…
