Challenges posed by infectious disease outbreaks have led to a range of participatory mobile phone-based innovations that use the power of crowdsourcing for disease surveillance. However, the dynamics of participatory behavior by crowds in such interventions have yet to be examined. This article reports results from a baseline evaluation of one…

The Internet is increasingly used to disseminate health information about diseases and prevention and to help in obtaining health services. Although technology can empower African Americans to adopt healthy lifestyles, the gap in usage between African Americans and Whites undermines the potential power of health Internet technology (IT) to…

Research has documented the use of tools in computer-based learning environments as problematic, that is, learners do not use the tools and when they do, they tend to do it suboptimally. This study attempts to disentangle cause and effect of this suboptimal tool use for experienced learners. More specifically, learner variables (metacognitive and…

In teacher education programmes, text-based portfolios are generally used to assess student-teachers' competence as new teachers. However, striking discrepancies are known to exist between the competencies reflected in a written portfolio and the competencies observed in actual classroom practice. Multiple assessments should be used to provide a…

This paper reports on a controlled experiment on the effects of three types of reflection triggers in an online course. Fifty-four volunteers, distributed in five groups, used these structured opportunities for reflection during learning. Results show that reflection triggers were extensively employed by the test persons and were perceived as…

A key problem in developing a virtual community for co-constructing learning resources is the need to have people volunteer to share their expertise. In this paper, we introduce the first phase of our research in which we examine strategies for encouraging participants to share in the system. We began by designing an intervention model based on…

An e-mail survey of special education directors was conducted to ascertain practices related to implementation of Response to Intervention (RTI) processes in North Carolina schools. The data indicate that special education directors have information about RTI as a method of identifying students with disabilities, but there is little consensus on…

As a result of the reauthorization of the Individuals with Disabilities Education Act (IDEA, 2004), Response to Intervention (RTI) became a legal and acceptable basis for determining special education eligibility. While there may be evidence that RTI has had positive effects on the prereferral process for special education in some schools, there…

Purpose: The purpose of this paper is to explore the extent and type of extra-curricular ESD-related practice in UK universities and to record opinions about the utility of such work. Design/methodology/approach: A postal questionnaire survey of all UK universities was undertaken in 2006. Over half (51 percent) of the UK's 140 universities with…

Much time is invested by markers in providing feedback to students that is personalised, aimed at providing them with information to feed forward into their next piece of work. Given the investment of time by tutors in the feedback process, we were necessarily concerned with how it is used by students and keen to explore and develop practice. This…

Research provides ample evidence that students rarely or often inadequately use instructional interventions in learning environments. This lack of use becomes especially problematic in open learning environments, where students have a large amount of control over tool use. In this contribution it is studied whether advice on the use of tools can…

Five hundred ninety-one clients from two university counseling centers indicated the help sources they had contacted before going to the counseling center. Analysis of the rank order in which help-givers were consulted yielded significant differences both within and across the counseling centers under two types of problems, emotional-social and…

Performance technology (PT) is complex, drawing theory from instructional design, organizational development, communications, industrial psychology, and industrial engineering to name a few. The Standards of Performance Technology developed for the certified performance technology designation codified the processes used in the practice of…
