This paper compares the use of confidence intervals (CIs) and a sensitivity analysis called the number needed to disturb (NNTD), in the analysis of research findings expressed as 'effect' sizes. Using 1,000 simulations of randomised trials with up to 1,000 cases in each, the paper shows that both approaches are very similar in outcomes, and each…

On the one hand, a growing amount of research discusses support for improving online collaborative learning quality, and many indicators are focused to assess its success. On the other hand, thinkLets for designing reputable and valuable collaborative processes have been developed for more than ten years. However, few studies try to apply…

Studies suggest that simulations and games not only improve target language skills, but they can also support knowledge creation regarding a broader variety of topics. Thus, we wanted to explore how playing an online simulation game affected knowledge of energy supply and its relationship to environmental and economic factors among learners of…

We surveyed researchers in the health and exercise sciences to explore different areas and magnitudes of bias in researchers' decision making. Participants were presented with scenarios (testing a central hypothesis with p = 0.06 or p = 0.04) in a random order and surveyed about what they would do in each scenario. Participants showed significant…

University entrance criteria can be a contentious topic, particularly in respect of equity. In this paper we discuss studies which demonstrate that revisions of entrance criteria which are designed with no explicit reference to equity issues can have a surprisingly positive impact on the fractions of disadvantaged subgroups admitted. We…

Designing for the needs of people with impairments has rarely been a significant feature of urban planning theory and education. Given the role of urban planners as shapers of the built environment and public policy, the prevalence of negative and misinformed attitudes among planners toward impaired populations has been highlighted as requiring…
