In Canada little research has been conducted on those who are the first in their families to attend university. Cultural reproduction theory suggests that such students would be less likely to engage in the type of activities that, according to the college impact model, contribute to academic achievement. In order to test these and other possibilities a longitudinal survey‐based study of domestic and international students was conducted at four Canadian universities. Overall it was found that university experiences did vary by the educational background of parents; however, such experiences were not always of consequence for academic achievement. 相似文献

Following Cronbach (1970) and others, it is useful to decompose test score variation into common factor, time‐specific, item‐specific, and residual components. In the traditional approach to factor analysis, only two sources of variance can be estimated: common factor variance and a uniqueness term that confounds specific sources of variation and residual error. When the same items are measured on different occasions, however, it is possible to separate specific variance and residual error. Two approaches, the first‐order approach described by Raffalovich and Bohrnstedt (1987) and a second‐order approach based on Jöreskog and Sörbom (1989; Jöreskog, 1974) are considered initially. The two approaches, although based on different rationales, both suffer a similar weakness in that two of the four sources of variance are confounded. In the Raffalovich and Bohrnstedt approach, time‐specific variance is confounded with common factor variance that generalizes across items and time. In the second‐order approach based on Jöreskog and Sörbom, time‐specific variance is confounded with residual error. Here we demonstrate that by combining features from both approaches we can eliminate these weaknesses and estimate all four of Cronbach's sources of variance, and that this combined approach is easily generalized to a wide variety of applications. 相似文献

Many introductory biochemistry students have problems understanding metabolism and acquiring the skills necessary to study
metabolic pathways. In this paper we suggest that this may be largely due to the use of a traditional teaching approach which
emphasises memorisation rather than understanding. We present an alternative approach to teaching carbohydrate metabolism
which is designed to promote understanding of pathways. The approach also enables regular monitoring of, and reflection on,
student progress and the identification of student reasoning and conceptual difficulties through the use of specially designed
problems. Preliminary results are presented giving examples of specific student difficulties and the extent to which they
were addressed by the alternative instructional approach. A qualitative evaluation of the approach is also presented.

The main thesis of this paper is that the construction and coordination of abstract units is central to mathematical activity in both numerical and geometric settings. Data were gathered from students in grade three through six, with four students being observed over a three year period. A consistent parallel was found in the sophistication of the types of units constructed in a geometric setting (tiling the plane) with their numeric activity. The tiling activity of the students was analyzed for evidence of the construction and coordination of units. Some students constructed rather sophisticated abstract composite units to facilitate their tiling with a particular shape while others had difficulty making a covering. Students who constructed abstract composite units in tiling did so also in adding and subtracting whole numbers. Evidence of unitizing and coordinating the units constructed was associated with advances in mathematical thinking. Unitizing seems to be a fundamental mental operation in coming to act mathematically. As mathematics activities are planned, it is important to provide opportunities for students to construct abstract composite units in both geometric and numeric settings. Emphasis on prescribed procedures such as subtracting with two-digit numerals may inhibit this construction process. 相似文献

Improving science education is often regarded as a priority for developing countries in order to promote longterm economic development. Thus initiatives, both government and foreign-aid sponsored, aimed at improving science education in developing countries abound. However, all too often the focus of such initiatives is limited to the development of science curricula, while the details of how the curricula will be implemented at school level are often neglected. This paper represents an effort to lay the groundwork for a theory of curriculum implementation with particular reference to developing countries. We have drawn on school development, educational change, and science education literature in order to develop three constructs that could form the heart of such a theory, namely, Profile of Implementation, Capacity to Innovate, and Outside Support. Six propositions are offered to suggest how the constructs may inter-relate as a basis for the development of the theory. The implementation of the natural sciences learning area of the South African Curriculum 2005 is used to illustrate the emerging theory. 相似文献

Previous research has shown that first-generation students confront greater problems than traditional students. In order to determine if this disadvantage extends to first-year grade-point averages (GPAs) in a commuter university in which the majority are first-generation students, 1,849 students at York University in Toronto were surveyed at the end of the first year and survey results were merged with information on grades from administrative records. The results of stepwise regression and classification and regression tree analyses show that traditional students enjoy a slight advantage in terms of GPA, and that while traditional students have higher levels of involvement than first-generation students, for both student groups involvement in various university activities contributes to GPA. 相似文献

In Canada, little attention has been paid to the extent to which job outcomes are the result of the human capital honed in university or of broader social dynamics. Combining the fundamental insights of status attainment and cultural reproduction theories with propositions of the college impact model, the current study examines the effects of cultural, social and human capital on four job outcomes two years after graduation from a Canadian university. Overall, it is found that variables measuring cultural and human capital have independent effects on job outcomes; however, the impact of social capital is minimal. The findings suggest that graduates' job outcomes are connected to broader social dynamics as well as to what they might learn in university. 相似文献

Universities establish various first yearprograms designed to assist students in thetransition from high school. American researchfocussing specifically on first yearadjustment, and general models of educationaloutcomes, suggest that early adjustment resultsin positive outcomes such as relatively highgrades and credit completion. An examinationof students entering York University in TorontoCanada in 1995 shows, however, that earlyadjustment may have only a very slight impacton first year grades and completed credits andno implications for five year outcomes. Findings such as these may indicate thatstudents who do not make an early adjustment touniversity in Canada may not necessarily bedisadvantaged. The difference between thesefindings, research on American campuses, andthe assumptions of American models of studentoutcomes, may result from general differencesin the post-secondary experience in the twonations. 相似文献

We examined the stability of responses to a multi‐item self‐esteem scale collected on five occasions over an 8‐year period. A wide variety of approaches were critically examined that considered the stability of means, individual differences (i.e., test‐retest correlations), and factor structures using traditional approaches (e.g., ANOVA and correlations) and structural equation models. Structural equation models based on multiple indicators provided a unified analytic approach for evaluating different aspects of stability and offered important advantages over traditional approaches. We describe a hierarchy of invariances and the nature of interpretations that are justified by different patterns of factor structure invariance associated with each level. We conclude that the assumptions underlying the typical repeated‐measures ANOVA approach to testing mean differences in longitudinal data are far more restrictive, less easily tested, and less likely to be met than those in the structural equation modeling approach advocated here, and that the use of ANOVA for this purpose requires a huge leap of faith that can rarely be justified on logical or empirical grounds. 相似文献
