Recent national reports have highlighted the contribution that the sciences make to the Australian economy. Many developed economies report perceived shortages of STEM qualified workers, and at the same time, many science graduates have difficulty in finding work, especially work in their discipline. Rational education design dictates that science curricula at all levels should be based on a realistic representation of the actual practice of science graduates. So where do Australian science graduates go postgraduation? Using the Australian national census data set, we present a focussed investigation into the occupational status of Australian science bachelor graduates, how this status varies with graduate age and gender, how this status varies between science degree specialisms and how this status compares to a range of other disciplines. We consider the implications of these findings for undergraduate science degree curriculum design. We find that Australian science bachelor graduates work in a wide range of occupations, and even immediately postgraduation, only a minority of science bachelor graduates are working in traditional science occupations. Occupational outcomes vary significantly between science degree specialisms. For a contemporary undergraduate science curriculum to reflect the occupational outcomes of science bachelor graduates, there is a balance required to ensure adequate technical preparation for those students who pursue a career in their discipline as science professionals and to also address the broader knowledge, skills and attitudes that will equip the majority of graduates from Australian science programs for successful employment, further education and active participation in their communities, using their science knowledge.  相似文献

In this article we report on the findings of a project funded by the Australian Office for Learning and Teaching and entitled “Learning Analytics: Assisting Universities with Student Retention.” While this project was primarily focused on retention as a potential outcome of learning analytics, its application could be related to the broader concept of student success. Student success allows for a focus on pedagogy and the use of learning analytics for the improvement of learning and teaching with a firm scholarly evidence base. The data gathered for the project provide the background for a discussion about the potential of learning analytics to inform the practice of the Scholarship of Teaching and Learning. A case study demonstrates the potential of this approach. Overall, clear pedagogical questions are important in the application of learning analytics to the Scholarship of Teaching and Learning, and we suggest potential ways to explore pedagogical questions with big data methods.  相似文献

Stoichiometric problem solving has always been a stumbling block for many students in introductory chemistry courses. Research has shown that it is quite common for students to rely on algorithms when doing stoichiometric calculations. In previous studies, students were confronted with simple stoichiometric problems that involved comparing molar masses with simple ratios to one another. It turned out that students very successfully used their own problem-solving strategies. It is typical of these strategies that students describe relations in their own words rather than applying mathematical calculations. In this paper, an alternate path to teaching introductory stoichiometry-based on the results of research-will be discussed. The recommendation given is to use problems of the kind mentioned above which can easily be solved by quick mental calculation.  相似文献

In 1997 a new governance act, based on the principles of New Public Management (NPM) was introduced at Dutch universities. The aims were to realise integrated management, to strengthen the position of executives at the central (executive board) and faculty (dean) levels, to introduce a Supervisory Board at the institution’s central level, and to increase the leeway for universities to design its own governance structure. This article reports on a large-scale evaluation of the governance act and focuses on student and staff participation in decision-making and on the actual appraisal of different actors within the universities (leaders, managers, staff, students) of the governance structure of their university. The empirical data reveal a mixed picture regarding the appreciation of the new governance structure, but overall—in contrast with many critical reviews of NPM in higher education—there seems to be considerable endorsement for the present situation.  相似文献

A procedure for evaluating candidate auxiliary variable correlations with response variables in incomplete data sets is outlined. The method provides point and interval estimates of the outcome-residual correlations with potentially useful auxiliaries, and of the bivariate correlations of outcome(s) with the latter variables. Auxiliary variables found in this way can enhance considerably the plausibility of the popular missing at random (MAR) assumption if included in ensuing maximum likelihood analyses, or can alternatively be incorporated in imputation models for subsequent multiple imputation analyses. The approach can be particularly helpful in empirical settings where violations of the MAR assumption are suspected, as is the case in many longitudinal studies, and is illustrated with data from cognitive aging research.  相似文献

Models of change typically assume longitudinal measurement invariance. Key constructs are often measured by ordered-categorical indicators (e.g., Likert scale items). If tests based on such indicators do not support longitudinal measurement invariance, it would be useful to gauge the practical significance of the detected non-invariance. The authors focus on the commonly used second-order latent growth curve model, proposing a sensitivity analysis that compares the growth parameter estimates from a model assuming the highest achieved level of measurement invariance to those from a model assuming a higher, incorrect level of measurement invariance as a measure of practical significance. A simulation study investigated the practical significance of non-invariance in different locations (loadings, thresholds, uniquenesses) in second-order latent linear growth models. The mean linear slope was affected by non-invariance in the loadings and thresholds, the intercept variance was affected by non-invariance in the uniquenesses, and the linear slope variance and intercept–slope covariance were affected by non-invariance in all three locations.  相似文献

School diversity and social justice: policy and politics   总被引:1,自引:1,他引:0  
This paper focuses on the long established diversity in the English education system – independent schools, grammar schools and religious schools – and in so doing explores tensions between education policy, politics and social justice. It explores the differential access to these different types of school, their social composition and implications for social justice and for wider society. It is argued that if social justice is to be a goal of government, further policy changes are needed over and above those that have already been made. However, the political challenges, which have limited policy changes to date, would be significant.  相似文献

This study examines the availability and use of information technology in public libraries in Kuwait. Specific areas addressed are (1) hardware/software, (2) patterns of connectivity such as LANs, Internet, etc., (3) training and development activities in support of information technology, and (4) future projections regarding the use of information technology. The study provides policy-makers and information professionals with previously unavailable baseline data concerning the use of computers and access to telecommunications networks in public libraries in Kuwait. A questionnaire sent to all public libraries (N=25) yielded a 92% response. Interviews with libraries' administrators and authorities were also undertaken to gather additional data. The results of the study reveal that many information technology inequalities exist among the libraries. Only eight libraries make use of computers and 15 are without any type of IT-related technology. The study shows that few libraries have connectivity, limited use of applications, and the implementation of an automated library system are slow moving. Factors impeding the development of information technology are planning, funding, human resources, and building structure. Recommendations are made with the intention to encourage the public library sector and information professionals in Kuwait to take a proactive position in overcoming the forces that hinder the development of IT.  相似文献

Standards are necessary to ensure that quality programs in Library and Information Science are delivered. The paper outlines the development of library education programs in Jordan. It places particular emphasis on the development, beginning in 1998, of the programs in private universities and describes the design of library standards for those programs at the undergraduate level. A historical look at Jordan, the higher education system, emergence and development of private universities are reviewed and standards are prescribed. The standards include rationales, objectives, curricula, study plans, basic and supplementary courses required, major subject areas of study, faculty qualifications, student admission, physical resources and facilities, and administration and financial support.  相似文献

Despite decades of studies of human infants, a still open question concerns the role of visual experience in the development of the ability to perceive complete shapes over partial occlusion. Previous studies show that newborns fail to manifest this ability, either because they lack the visual experience required for perceptual completion or because they fail to detect the pattern of motion. To distinguish these possibilities, newborns' perception of a center-occluded object was tested, using stroboscopic motion. Infants (mean age of 72 hr) perceived the object as a connected unit, providing the first evidence that the newborn is capable of filling in gaps in the visible surface layout when the relevant visual information can be detected by his or her immature visual system.  相似文献
