Public concerns over the possible effects of school segregation on immigrant and ethnic majority religiosity have been on the rise over the last few years. In this paper we focus on (1) the association between ethnic school composition and religious salience, (2) intergenerational differences in religious salience and (3) the role of ethnic school composition for intergenerational differences in religious salience. We perform analyses on religious salience, one five-point Likert scale item measuring religious salience among 3,612 16-year-old pupils in Belgian secondary schools. National origin was used as a proxy for ethnicity. Ethnic minority pupils in schools with a higher share of ethnic minorities tend to be more religious. This relation holds for Muslim as well as other religious and ethnic minorities. Ethnic school composition also moderates the relationship between migrant generation and religious salience: second generation migrants tend to be more religious in ethnic minority dominated schools. For ethnic Belgians the association is moderated by their religious affiliation: Catholics tend to be more religious, while non-affiliated ethnic Belgians are less religious in schools with a higher share of ethnic minority pupils.  相似文献

In this contribution, a theoretical and empirical framework based on work carried out at the Open universiteit (Ou) for a new approach towards the design, production and delivery of flexible, interactive learning materials for distance education is presented.

In the Research and Development centre of the Ou, a project has concentrated on the innovation of current approaches. This framework can also be considered as an advance organizer to reading the remaining articles from the Open universiteit in this issue of Distance Education.

A key feature of the innovation is that during the design phase, course developers have to define ‘models’ of the materials to be developed: a content model, a support model, a student model and the learning path. From a flexibility point of view especially, the ‘student model’ is of importance since it defines the student variables that will be taken into account when developing/ presenting alternative materials (basic content and/or embedded support). A computer‐based system, the ‘Interactive Learning and Course Development Environment (ILCE)’, was developed to support the work of course development teams and tutors on the one hand, and students on the other hand. The development system supports the work of the developers; the delivery system supports the study process of students. The delivery is realised as an on‐line course, on the World Wide Web.

Students start working with the ILCE‐system by following an intake procedure. They can make choices in relation to student variables that have been defined in the student model (profession, study intentions, context, etc.). Next, they can ‘on the fly’ generate a course. Rom the large repository of learning materials only those materials are selected and compiled that are in line with the student model of this specific student Furthermore, they can choose to study the materials on screen and/or make prints of the materials. Of course, in printing the materials they lose the interactive and dynamic possibilities of the computer learning environment  相似文献

Abstract

Recently, researchers have used multilevel models for estimating intervention effects in single-case experiments that include replications across participants (e.g., multiple baseline designs) or for combining results across multiple single-case studies. Researchers estimating these multilevel models have primarily relied on restricted maximum likelihood (REML) techniques, but Bayesian approaches have also been suggested. The purpose of this Monte Carlo simulation study was to examine the impact of estimation method (REML versus Bayesian with noninformative priors) on the estimation of treatment effects (relative bias, root mean square error) and on the inferences about those effects (interval coverage) for autocorrelated multiple-baseline data. Simulated conditions varied with regard to the number of participants, series length, and distribution of the variance within and across participants. REML and Bayesian estimation led to estimates of the fixed effects that showed little to no bias but that differentially impacted the inferences about the fixed effects and the estimates of the variances. Implications for applied researchers and methodologists are discussed.  相似文献

Gough and Tunmer’s (1986) simple view of reading (SVR) proposed that reading comprehension (RC) is a function of language comprehension (LC) and word recognition/decoding. Braze et al. (2007) presented data suggesting an extension of the SVR in which knowledge of vocabulary (V) affected RC over and above the effects of LC. Tunmer and Chapman (2012) found a similar independent contribution of V to RC when the data were analyzed by hierarchical regression. However, additional analysis by factor analysis and structural equation modeling indicated that the effect of V on RC was, in fact, completely captured by LC itself and there was no need to posit a separate direct effect of V on RC. In the present study, we present new data from young adults with sub-optimal reading skill (N = 286). Latent variable and regression analyses support Gough and Tunmer’s original proposal and the conclusions of Tunmer and Chapman that V can be considered a component of LC and not an independent contributor to RC.  相似文献

A problem posing orientation teacher education course has been developed at Utrecht University for physics students. For that purpose, an inventory study of the 1995 orientation physics course was carried and is reported here. The research focus was: What were students’ initial motives for attending the orientation course? How do these motives change during the course? In this study, students were asked at three different moments to describe (the change in) their motives for taking part in the course: at the start, halfway and at the end of the course. Moreover, students’ logbooks and learning reports were analysed. Five motives have been found, the most important being the desire to learn whether being a secondary school teacher will suit them, with job prospects and acquiring presentation skills being important motives as well. These results offer a basis for the development of a preliminary ‘didactical structure’ for the course.  相似文献

This project describes the development of a universal student friendly distance learning (DL) provider system via the Internet and in particular the development of a lab environment for engineering students in ICT. Application of most DL courses is still hampered by the need for high-speed links, unrealistic computer and software resources at the student site and the impossibility to run Windows or Unix applications over the Internet. The described solution solves practically all of these problems. Moreover, since courses, (simulation) programs, databases, etc. can be added or changed, the system is not only teacher friendly but also costeffective. The major part of the work concerns the design of an electronic lab environment at the university that can be remotely used via the Internet. The main aim is to provide the student with meta-cognitive knowledge as can be provided only by real lab exercises. In this case the student must work him/herself through a course on passive filters. After choosing the right topology for the particular filter-lab task, he/she must design the correct circuit diagram and verify it with a standard circuit simulation program. Next, with a matrix shown on screen, he/she interconnects the circuit components and measuring equipment. The results of the measurements performed at the lab in the university are sent back to the student (via the Internet). The lab report is automatically generated. Simultaneously, the set up and the different instruments can be visualized via a web camera. Thus, the design of the electronic lab environment is user, student and teacher friendly.  相似文献

This article focuses on the design of competency-based performance assessment in e-learning. Though effort has been invested in designing powerful e-learning environments, relatively little attention has been paid to the design of valid and reliable assessments in such environments, leaving many questions to educational developers and teachers. As a solution to this problem, a systematic approach to designing performance assessments in e-learning contexts is presented, partly based on the 4C/ID model. This model enables the construction of realistic whole tasks instead of advocating education that is restricted to more isolated skills. A new assessment procedure also implies an alternative view of instructional design, learning and assessment. The requirements for the learning environment are addressed. Examples from a virtual seminar are presented to illustrate the design approach. The article concludes with the identification of possible pitfalls related to the approach and gives directions for future research.  相似文献
