Justice and cultural conflict: Racism,sexism, and instructional materials     

Joel Taxel 《Interchange》1978,9(1):56-84

Conclusions This paper has sought to raise questions about the limits we have imposed on ourselves as we discuss the relationship between racism, sexism, and instructional materials. In addition to attempting to outline the historical evolution of concerns about the content of curricular materials, and the manner in which this issue is currently being debated, I have tried to demonstrate that the ground rules and definitions we have accepted have limited our ability to apprehend the real complexity of the issue (e.g., a definition of censorship which omits the notion of covert censorship). Perhaps the most important belief which I have sought to question is that the content of literary and curricular materials can be discussed in isolation from the ideologies which they consciously or unconsciously manifest. There is a relationship between these ideologies and the wider distribution of power and resources in society. To discuss challenges to racially or sexually biased instructional materials exclusively in terms of a perceived threat to intellectual freedom and in absence of a discussion of the role such materials play in the continuation and re-creation of racial and sexual discrimination in society is, as has been stated, to ignore matters which demand consideration. It is my conviction that the debate surrounding this question has, for too long, been abstracted from the concrete historical concerns of those directly involved, and has ignored the appeals to justice and fairness which adhere to the claims of those demanding redress of past grievances.Furthermore, the debate has been too often guided by assumptions (e.g., the existence of schools as an open and free marketplace for the exchange of all ideas) which simply cannot withstand close scrutiny. It is clear to me that the perspectives offered by the sociology of school knowledge offer the means to make possible a fuller disclosure of the serious issues raised by this controversy.  相似文献   

Differential versus equal student subsidies in post-secondary education: A current Canadian dispute     

E. G. West 《Higher Education》1974,3(1):25-42

This paper examines a current proposal that students in higher education should have equal subsidies. The proposal has recently been made on grounds of efficiency and is therefore linked with the justification of subsidies because of public benefits (externalities) from education. The argument is that since we are ignorant of the differential strengths of public benefits from each educational program, it is a safe rule to subsidize each at an equal rate. This equality argument is further supported in this paper with the observation that marginal public benefits diminish with increasing educational duration. This efficiency argument is clearly distinguishable from that of equity or equality of opportunity.The strength of the argument is next tested against the objections to it that are now being made by the Ontario Commission on Post-Secondary Education. Evidence of the degree of present inequality in subsidization in Ontario is fully surveyed. It is shown that the Commission is reluctant to reduce the inequality because this will mean charging full fees for the last stages of professional training. The Commission fears that this would result eventually in the raising of professional fees to the public.This article finally produces an economic model that shows that the Commission's fears are groundless. The case for switching the subsidies in favour of the earlier years of education is indeed stronger than appears at first sight because of the monopolistic tendencies of the professions concerned.  相似文献   

Occupational Outcomes for Bachelor of Science Graduates in Australia and Implications for Undergraduate Science Curricula     

Stuart Palmer  Malcolm Campbell  Elizabeth Johnson  Jan West 《Research in Science Education》2018,48(5):989-1006

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   

Preschoolers’ learning when pictures do not tell the whole story     

Nancy Digdon  Michael Pressley  Joel R. Levin 《Educational technology research and development : ETR & D》1985,33(2):139-145

Preschool children heard two ten-sentence stories. Each sentence was accompanied by two pictures (one of the subject and one of the object of the sentence), by a picture of the sentence’s subject, by a picture of the sentence’s object, or by no pictures. After presentation of the stories, the children answered questions requiring recall of the sentence objects. Only the two-picture illustration variation produced significantly beffer learning relative to no-picture control performance. This finding held both when children were instructed to make mental images representing the prose and when they simply listened to the text. The results are relevant both to theories of children’s imagery and to practical issues about how to illustrate children’s texts. This research was supported by a grant to the second author from the Natural Sciences and Engineering Research Council of Canada.  相似文献   

Applying Learning Analytics to the Scholarship of Teaching and Learning     

Jurg Bronnimann  Deborah West  Henk Huijser  David Heath 《Innovative Higher Education》2018,43(5):353-367

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   

On Enhancing Plausibility of the Missing at Random Assumption in Incomplete Data Analyses via Evaluation of Response-Auxiliary Variable Correlations     

Tenko Raykov  Brady T. West 《Structural equation modeling》2016,23(1):45-53

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   

Longitudinal Measurement Non-Invariance with Ordered-Categorical Indicators: How are the Parameters in Second-Order Latent Linear Growth Models Affected?     

Yu Liu  Stephen G. West 《Structural equation modeling》2018,25(5):762-777

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   

Impact of a Computer-Based Physics Instruction Program on Pupils' Understanding of Measurement Concepts and Methods Associated with School Science     

Joel K. Kiboss 《Journal of Science Education and Technology》2002,11(2):193-198

A set of instructional materials was developed for the teaching of measurement, as part of a classroom innovation for science instruction. This project involved collaborative groupings with the computer as an instructional tool for learners to interact with. A computer-based physics instruction module was developed from a physics course dealing with the concept of measurement. This paper presents the results of an empirical evaluation undertaken over a 6-week period with 118 subjects (ages 12–17) randomly selected Form I pupils in Nakuru district, Kenya. Analysis of the quantitative data showed that the intervention promoted pupils' understanding of measurement concepts and skills, in that the subjects in the treatment groups demonstrated better at the posttests than their counterparts in the true control group. Also, the learning protocols differed markedly in favor of the subjects exposed to the treatment.  相似文献   

School diversity and social justice: policy and politics   总被引：1，自引：1，他引：0  

Anne West  Peter Currie 《Educational studies》2008,34(3):241-250

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
