When is a song a song? The development of singing in early childhood

During the second year of life, babies actively play with sounds they produce. Their sound-play often has musical qualities such as pitch, rhythm, and melodic contour, but it is not the same as singing. Singing is a complex activity, one requiring skills that usually take the entire preschool years to develop.Lyle Davidson is a professor at the New England Conservatory of Music, Boston, MA. W.

The Accreditation of Prior Experiential Learning in Higher Education: A Discourse on Rationales and Assumptions

This paper explores some of the issues and benefits surrounding the process of accreditation of prior experiential learning (APEL) as one key institutional 'building block' for meeting the needs of adults who wish access to UK higher education institutions (HEIs) course provision. Arguments are advanced whereby APEL could help to 'unlock doors' to HEIs for those (mostly part-time students), who have traditionally been denied access or advanced standing to HE courses because of personal, socio-economic or institutional constraints. The paper also provides a basis for APEL based on educational grounds. Reference to a three year study/project in a Canadian institution, where criteria were evolved that eventually led to the establishment of APEL policy and procedures along with the evolution of the necessary infrastructure, is also made. APEL is also presented as a human resource/career development process that can gather momentum, gain commitment and support from the private sector.     

Evaluating the potential of teacher-designed technology-based tasks for meaningful learning: Identifying needs for professional development

With technology increasingly being introduced into classrooms worldwide, stakeholders are asking whether ICT provides educational value. It is not simply having access to technology but how teachers use it that will determine its worth to education. Thirty-three teacher-designed technology-based tasks from eight subject areas were analysed for their effective use of ICT, and their potential to involve students in constructivist learning. Few of the tasks made effective use of ICT for meaningful learning, for reasons associated with teachers’ beliefs, attitudes, and missing TPACK components or competencies. These factors provide the basis for a model of areas to target when structuring professional development courses to help teachers better utilize educational ICT to design meaningful learning tasks.     

Circulating Thrombotic Risk Factors in Young Patients with Coronary Artery Disease Who Are on Statins and Anti-platelet Drugs

Thrombotic risk factors may contribute to premature coronary artery disease (CAD), in addition to the conventional risk factors. There is paucity of data on studies evaluating the role of thrombotic factors in premature CAD in Indian patients. Thus a case–control study was performed to evaluate the role of thrombotic and atherogenic factors in young patients with angiographically proven CAD who are on treatment with statins and anti-platelet drugs. 152 patients (≤55 years) with angiographically proven CAD and 102 asymptomatic controls were recruited. Clinical and biochemical data were obtained in both groups. Blood levels of thrombotic factors-fibrinogen, antithrombin-III, tissue-plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), von-Willebrand factor (v-WF), lipoprotein(a) [Lp(a)] and homocysteine were analyzed. Patients had high levels of conventional CAD risk factors (diabetes mellitus, smoking, hypertension, dyslipidemia and positive family history) compared to controls. Logistic regression analysis revealed that low antithrombin-III (odds ratio/OR 11.2; 95 % confidence interval/CI 2.29–54.01), high fibrinogen (OR 6.04; 95 % CI 1.09–33.21) and high Lp(a) (OR 4.54; 95 % CI 0.92–22.56), as important, independent risk factors in patients. PAI-1(OR 0.15; 95 % CI 0.03–0.69) levels were significantly lower in patients. But other thrombotic risk factors studied (t-PA, v-WF and homocysteine) were comparable among patients and controls. The treatment using statins and anti-platelet drugs might be contributing to the control of some of the thrombotic risk factors. The strategies aiming at lowering the levels of thrombotic risk factors along with conventional risk factors may be useful in primary and secondary prevention of CAD.     

Using the Content of Online Privacy Notices to Inform Public Policy: A Longitudinal Analysis of the 1998-2001 U.S. Web Surveys

In the United States, Congress has had a long-standing interest in consumer privacy and the extent to which company practices are based on fair information practices. Previously, public policy was largely informed by anecdotal evidence about the effectiveness of industry self-regulatory programs. However, the Internet has made it possible to unobtrusively sample web sites and their privacy disclosures in a way that is not feasible in the offline world. Beginning in 1998, the Federal Trade Commission relied upon a series of three surveys of web sites to assess whether organizations post online privacy disclosures and whether these disclosures represent the U.S. definition of fair information practices. While each year's survey has provided an important snapshot of U.S. web-site practices, there has been no longitudinal analysis of the multiyear trends. This study compares a subset of equivalent individual-level web-site data for the 1998, 1999, 2000, and 2001 web surveys. Implications for using this type of research to inform public policy are discussed.     

CHANGING VISIONS OF EXCELLENCE IN ONTARIO SCHOOL POLICY: THE CASES OF LIVING AND LEARNING AND FOR THE LOVE OF LEARNING

In this essay, Rosa Bruno‐Jofré and George Hills examine two major Ontario policy documents: 1968's Living and Learning and 1994's For the Love of Learning. The purpose is, first, to gain insight into the uses of the term “excellence” in the context of discourse about educational aims and evaluation, and, second, to explore how these uses may have changed over time. Bruno‐Jofré and Hills employ the conceptual framework developed by Madhu Prakash and Leonard Waks to elucidate the varied notions of excellence contained in the two reports. Bruno‐Jofré and Hills argue that Living and Learning is an eclectic report that creates continuity by aligning itself with the pedagogically progressive tradition in Ontario; that propounds a holistic conception of excellence centered on the all‐around development of the self; and that seeks simultaneously to secure a sense of being Canadian while dealing with rapidly emerging social fragmentation. For the Love of Learning, in contrast, attempts to combine a technical view of excellence in education (stressing various literacies and skills as measurable indicators) with the principles of caring and the goals of social responsibility. Each report can be seen as an attempt to respond to the expectations of a population that had become increasingly diverse in the interval between the two reports. What is cause for concern in terms of policymaking, Bruno‐Jofré and Hills conclude, is the turn away from broader, more comprehensive and coherent views of excellence in education toward narrower and more fragmented accounts that are preoccupied with various types of literacy or loosely related vocational and other skills. The effect of this shift is to leave educational policy and practice in the schools essentially rudderless.
