Modern education emphasizes the need to flexibly personalize learning tasks to individual learners. This article discusses
a personalized task-selection model with shared instructional control based on two current tendencies for the dynamic sequencing
of learning tasks: (1) personalization by an instructional agent which makes sequencing decisions on the basis of learner’s
expertise, and (2) personalization by the learner who is given control over – final – task selection. The model combines both
trends in a model with shared instructional control. From all available learning tasks, an instructional agent selects a subset
of tasks based on the learner’s performance scores and invested mental effort (i.e., system-control). Subsequently, this subset
is presented to the learner who makes the final decision (i.e., learner control). A computer-assisted instructional program
has been developed to put the model into practice and preliminary results are discussed. The model can be used to increase
the efficiency and effectiveness of instruction and to make it more appealing by providing the learner an optimal level of
control over task selection.

Whether fading support for problems affects accuracy of hypertext navigation and problem performance is investigated in this study. In a student-centered e-learning environment conceptual support is added to help domain novices get an overview of the problem domain, while strategic support is provided to help domain novices get insight into the problem demands. It is assumed that such support helps learners because it lowers the cognitive load of navigation. This frees up cognitive capacity for learning provided that the support fades and becomes less intrusive as a function of learner expertise. It is hypothesized that fading support during practice helps learners navigate more accurately during practice and achieve a higher practice and test performance as compared to learners receiving full support or no support during practice. This study confirms the beneficial effects of fading support on navigation but no effects of fading were found on practice and test performance. 相似文献

Multi‐ethnic schools in Flanders are frequently portrayed – both in popular media and research – as highly problematic working environments for (beginning) teachers. This article reports on an exploratory study of beginning teachers’ experiences in one secondary multi‐ethnic school in Flanders. Based on data from questionnaires, document analysis and semi‐structured interviews with both six beginning teachers and two mentors, the study concluded that the structural and cultural working conditions as well as the personal belief systems of the teachers were essential to understand the actual impact of the multi‐ethnic character of the school on new teachers’ job experiences. Due to the mediating role of these factors, beginning teachers do not consider the multi‐cultural character of their working environment as problematic as such. 相似文献

The aim of this study was to examine whether the construction of integrated knowledge structures by students can be stimulated by concept mapping and by better visualization of concepts and their interrelationships. The investigation was carried out in regular teaching settings: chemistry courses in secondary schools in Flanders, in the domain of electrochemistry. A significant positive effect of extra attention to visualization on the learning achievement of students was found. However, significant effects of concept mapping as an instruction method could not be detected under the given research conditions. 相似文献

Some literature on elder abuse recommends, and practitioners claim, that there should be better assessment and screening tools. In order to improve the accuracy of measurement instruments, the purpose of this article is threefold: (a) describing the construction of an instrument with formative indicators and the survey design about the sensitive topic of elder abuse, (b) development of an analytic strategy to improve the precision of the measures by (c) evaluating the measurement instrument through quality criteria against outcomes of the instrument. We randomly selected 2,880 home-dwelling older women aged 60 and above from five European Union countries who participated in a survey on elder abuse. Prevalence data on abuse against older women was gathered using a postal (BE, FI, PT), face-to-face (BE, LT), and telephone survey (AT) but using an identical instrument. A table with outcome measures was calculated to evaluate the formative indicators of the measurement instrument, and a decision strategy for item reduction was developed. The results suggest that 12 (35%) of the original 34-indicators instrument can be omitted. The adapted version can provide the same elder abuse prevalence rates (reliability) with the same negative associations in terms of life quality (validity). The results indicate in an applied way how an elder abuse instrument can be evaluated and further developed using formative measures. 相似文献

This study critically addresses the assumptions made by educators and providers in the field of Dutch second language (L2) acquisition about the online learning of Dutch L2. These include assumptions about advantages and disadvantages of online language learning, such as flexibility, learner autonomy, enhanced opportunities for remediation and differentiation versus disadvantages including the solitary learning mode, delayed feedback or high production costs. Even though stakeholders perceive a clear need for online Dutch L2 learning, and are aware of several advantages of online language learning, the current implementation level is still low. The perceived disadvantages might be a factor hindering the transition to online learning. A reorientation of the current provision of Dutch L2 courses is perceived as desirable, with self-directed, needs-oriented and customised learning as the key concepts. The outcomes shed light on perceptions that foster or hinder the development of online language courses for adult migrants, and could resonate with language professionals worldwide. 相似文献

Troubleshooting in a practice situation requires two types of information, namely for reasoning about the problem-cause and for finding an adequate solution (declarative information) and for manipulating the environment (procedural information). It is hypothesized that presenting this information piece-by-piece during practice (i.e., presentation of declarative and procedural information separately) frees up working memory and facilitates learning. Moreover, this effect is augmented when both information types are presented just-in-time (i.e., declarative information before practice and procedural information during practice). This should yield highest test performance and instructional efficiency, which is defined as higher test performance combined with lower mental effort during practice. Eighty-five students (49 male, 36 female; M = 15.2 years, SD = .59) participated in a 2 × 2 factorial experiment with the factors timing of declarative information and timing of procedural information, both before or during practice. Transfer test scores and transfer efficiency scores support the first hypothesis; the second hypothesis was not supported. 相似文献

The aim of this paper was to discuss the role of food preservation science and technology in the conservation of complex food-based installations. By introducing the principles of food science and food preservation into the decision-making process for the conservation of contemporary art, more insight on conservation and presentation possibilities was created. Considering the installation Piece in Ghent (P.I.G.) by Jason Rhoades, which contains French fries, the principles of food preservation science were evaluated. The preservation of the original foods was discussed against the potential of a reproduction of the foods. The context for conservation was determined by analysing the artist's intention, the production method of the artwork, and the degradation processes of the food materials. From the results obtained, guidelines to preserve the ‘original’ foods were proposed, as well as guidelines to reproduce foods that can last longer. The study demonstrated that food preservation science contributed to the development of effective strategies for the conservation of contemporary food-based art. 相似文献

Tutors have only limited time to support the learning process. In this paper, we introduced a model that helps answer the questions of students. The model invoked the knowledge and skills of fellow students, who jointly formed an ad hoc, transient community. The paper situated the model within the context of a Learning Network, a self‐organised, distributed system, designed to facilitate lifelong learning in a particular knowledge domain. We discussed the design of the model and explained how we selected and supported capable peers. Finally, we examined the calibration of the model and a simulation, which was intended to verify if the model is fit for use in experiments with students. The results indicate that, indeed, it is possible to identify and support capable peers efficiently and effectively. 相似文献

As assessment methods are changing, the way to determine their quality needs to be changed accordingly. This article argues for the use Competence Assessment Programs (CAPs), combinations of traditional tests and new assessment methods which involve both formative and summative assessments. To assist schools in evaluating their CAPs, a self-evaluation procedure was developed, based on 12 quality criteria for CAPs developed in earlier studies. A self-evaluation was chosen as it is increasingly used as an alternative to external evaluation. The CAP self-evaluation is carried out by a group of functionaries from the same school and comprises individual self-evaluations and a group interview. The CAP is rated on the 12 quality criteria and a piece of evidence is asked for to support these ratings. In this study, three functionaries from eight schools (N = 24) evaluated their CAP using the self-evaluation procedure. Results show that the group interview was very important as different perspectives on the CAP are assembled here into an overall picture of the CAP's quality. Schools seem to use mainly personal experiences to support their ratings and need to be supported in the process of carrying out a self-evaluation. 相似文献
