Effect of instructional videotapes on AIDS knowledge and attitudes

The effectiveness of four commercial videotape presentations in changing AIDS knowledge and attitudes among 584 college students was evaluated in a pre-post design with control group and follow-up. AIDS knowledge and attitudes were measured prior to, immediately after, and 4 to 6 weeks following presentation of the informational videotapes. In addition, subjects rated each videotape on several specific dimensions, including overall quality. The effects of age, sex, prior exposure to AIDS information, and presence v absence of post-presentation discussion were measured as covariates. In general, there was a significant immediate increase in AIDS knowledge attributable to all four videotapes (p less than .001). These gains persisted until follow-up, with no erosion for three of the four tapes. With the exception of perceived effectiveness of AIDS prevention methods (p less than .001), attitudes toward AIDS showed no change as a result of exposure to any of the videotapes (p greater than .05). Viewer ratings showed two of the videotapes to be superior in terms of perceived overall quality (p less than .05). There were also differences in ratings of videos on other dimensions. Among the covariates, there was no relationship at time of follow-up between post-presentation discussion v no discussion and either knowledge gain or attitude change. Sex was related to one attitude component, with women perceiving the AIDS epidemic as more severe than men (p less than .001).     

A literature review about usability evaluation methods for e-learning platforms

The usability analysis of information systems has been the target of several research studies over the past thirty years. These studies have highlighted a great diversity of points of view, including researchers from different scientific areas such as Ergonomics, Computer Science, Design and Education. Within the domain of information ergonomics, the study of tools and methods used for usability evaluation dedicated to E-learning presents evidence that there is a continuous and dynamic evolution of E-learning systems, in many different contexts -academics and corporative. These systems, also known as LMS (Learning Management Systems), can be classified according to their educational goals and their technological features. However, in these systems the usability issues are related with the relationship/interactions between user and system in the user's context. This review is a synthesis of research project about Information Ergonomics and embraces three dimensions, namely the methods, models and frameworks that have been applied to evaluate LMS. The study also includes the main usability criteria and heuristics used. The obtained results show a notorious change in the paradigms of usability, with which it will be possible to discuss about the studies carried out by different researchers that were focused on usability ergonomic principles aimed at E-learning.     

Initiating e-learning by stealth,participation and consultation in a late majority institution

Abstract

The extent to which opportunities afforded by e-learning are embraced by an institution can depend in large measure on whether it is perceived as enabling and transformative or as a major and disruptive distraction. Most case studies focus on the former. This paper describes how e-learning was introduced into the latter environment. The sensitivity of competing pressures in a research intensive university substantially influenced the manner in which e-learning was promoted. This paper tells that story, from initial stealth to eventual university acknowledgement of the relevance of e-learning specifically to its own context.

Teaching research in practice courses

Students of social work and related professions are often resistant to study research. Efforts to resolve this problem have focused on making research courses more experiential and developing a 'user friendly' curricula. This article presents an experimental strategy used in one American school of social work to teach research-related content within the context of a practice course. Students' and teachers' evaluations indicate that this may be useful to enable students to acquire tools with which to use and conduct research.     

Assessing the relevance of higher education courses

The establishment of the European Higher Education Area has involved specifying lists of professional competencies that programs are expected to develop, and with this the need for procedures to measure how every course within a higher education program is aligned with the program's competencies. We propose an instrument for characterizing this alignment, a process that we call assessing the relevance of a course. Using information from the course syllabus (objectives, contents and assessment scheme), our instrument produces indicators for characterizing the syllabus in terms of a competence list and for assessing its coherence. Because assessment involves quality, the results obtained can also be used to revise and improve the course syllabus. We illustrate this process with an example of a methods course from a mathematics teacher education program at a Spanish university.     

Developing theISEE instructional software for sampling and statistical inference: Dilemmas and pitfalls

This article analyzes the social conditions that facilitated and impeded the development of a computer program for teaching statistical sampling. It discusses occupational, developmental, technical, and pedagogical dilemmas encountered during this process, and analyzes the structural conditions necessary for overcoming sociological ambivalence toward teaching and computing, as well as the tendency for software creation to be marginalized. Finally, some helpful conditions intrinsic to the process of software development are identified.     

Crisis management during "live" supervision: clinical and instructional matters

In this article, we illustrate two examples of "live" supervision with marriage and family therapy trainees whose clients presented in the therapy room in immediate crisis. The case examples, one a client with suicidal thoughts and the other a parent who had struck her child, demonstrate how the university-based therapy team managed the recursive clinical and supervision processes that unfolded during the sessions. We present the case examples from the perspective of both supervisees and supervisor, discussing how our different experiences of the supervision unfolded in real time. Case discussion and reflections later in the article illustrate the need for an open, transparent, dialogical process throughout supervision. A case is made for supervisory participants to create alternative formats in which multiple supervisory voices can be heard.

Nest-site selection and nest depredation of semi-aquatic turtles on golf courses

Urban landscapes present various challenges to semi-aquatic turtle reproduction. In developed regions, golf courses may provide some of the best remaining habitat for turtle populations. We explored nest-site selection of eastern painted turtles (Chrysemys picta) at a golf course pond in Davidson, North Carolina, USA, and modeled nest-site preference using Akaike Information Criterion, with the best supported model favoring nests surrounded by mulch and mowed grass. Additionally, we evaluated nest depredation rates using simulated turtle nests and found that golf course ponds did not have significantly greater nest depredation compared to urban and rural ponds. Our results suggest that golf courses may offer suitable habitat for turtle reproduction in developed areas.     

A strategy for monitoring and evaluating massive open online courses

We argue that the complex, innovative and adaptive nature of Massive Open Online Course (MOOC) initiatives poses particular challenges to monitoring and evaluation, in that any evaluation strategy will need to follow a systems approach. This article aims to guide organizations implementing MOOCs through a series of steps to assist them in developing a strategy to monitor, improve, and judge the merit of their initiatives. We describe how we operationalise our strategy by first defining the different layers of interacting agents in a given MOOC system. We then tailor our approach to these different layers. Specifically, a two-pronged approach was developed, where we suggest that individual projects be assessed through performance monitoring; assessment criteria for which would be defined at the outset to include coverage, participation, quality and student achievement. In contrast, the success of an overall initiative should be considered within a more adaptive, emergent evaluation inquiry framework. We present the inquiry framework we developed for MOOC initiatives, and show how this framework might be used to develop evaluation questions and an assessment methodology. We also define the more fixed indicators and measures for project performance monitoring. Our strategy is described as it was developed to inform the evaluation of a MOOC initiative at the University of Cape Town (UCT), South Africa.     

Colonial and post-colonial aspects of Australian identity

Since the 1988 Bicentennial and the 2001 centenary of federation celebrations colonial images have flourished in Australia, highlighting the roles of convicts and free settlers during early colonization. Old sites, such as Port Arthur have been re-invigorated, and in 2004 Tasmanians celebrated the bicentenary of 'white' settlement. However, social scientists have given little attention to the role of colonial and post-colonial figures and myths as aspects of Australian national identity. We seek to address this issue by examining how convicts, free settlers, bushrangers and ANZACs are associated with contemporary identity in Australia. We examine evidence from the 2003 Australian Survey of Social Attitudes and find that historical figures such as the ANZACs and post-World War II immigrants comprise important aspects of national identity. A substantial majority of Australians judged ANZACs to be important, countering recent claims of the 'demise of the digger'. Sporting heroes are also at the core of Australian identity. Colonial figures appear to be far less important, although views on national identity vary according to social location. In particular, left-wing, university educated, younger, postmaterialist Australians view convicts and bushrangers as relatively important, indicating the salience of the larrikin in Australian identity.     

Environmental and ethical aspects of international migration

"U.S. immigration policy has a beneficent intent. However, recent work suggests that the signal it sends internationally--that emigration can be relied upon to relieve local (Third World) population pressure--tends to maintain high fertility rates in the sending country. This effect is counterproductive because high fertility is the primary driver of rapid population growth. In addition, it appears that the relatively open U.S. immigration policy has resulted in a rate of domestic population growth that threatens both the well-being of American labor and cherished environmental values."
