Background: When educational interventions are carried out, it is important that they are undertaken in a way that is aligned with the intervention plan: in other words, that they demonstrate fidelity to the intervention. A significant research issue is how fidelity can be monitored in a time-efficient and cost-effective way in classrooms and…

Studying and solving geometry questions are the most challenging parts of mathematics for visually impaired students (VIS). This study begins with the needs assessment to identify the needs of VIS, which shows that technology-assisted effective teaching and learning are not available for VIS to learn geometry. Therefore, this study focuses on…

Objective: Millions of people use mobile phone or computer-based applications--apps--to maintain their mental health and connect with treatment providers through text- and video-based chat functions. The present study sought to understand young adults' motivations for adopting this technology using the "unified theory of acceptance and use of…

Although the learning of programming language is critical in science and technology education, it might be difficult for some students, especially novices. One possible reason might be the fact that programming language, especially for three-dimensional (3D) applications, is too complex and abstract for these students to understand. Programming…

This paper focuses on understanding the role that affordances played in children's learning performance and efficiency during clinical interviews of their interactions with mathematics apps on touch-screen devices. One hundred children, ages 3 to 8, each used six different virtual manipulative mathematics apps during 30-40-min interviews. The…

Part of a larger initiation mixed methods study (Greene, Caracelli, & Graham, 1989), this paper discusses the changes in young children's learning performance and efficiency (one element of the quantitative portion of the larger study) during clinical interviews in which each child interacted with a variety of virtual manipulative…

Critics call computerized innovations and other changes in the workplace examples of the employers'"dumbing down" of jobs for illiterate workers. Others disagree and say the changes free workers from routine, monotonous tasks and permit them to learn more complex procedures and to take on more responsibility. Findings of a survey of business…

Two tailored testing models, specifying procedures by which the correctness of examinees' responses to a fixed number of test items are predicted by presenting as few items as possible to the examinee, were compared for their efficiency. The models differ in that one requires reconsideration of each prediction whenever additional information is…
