The Reflective Tutorial Dialogue System (ReTuDiS) is an open learner modelling system for text comprehension. The system makes diagnosis of the learners’ cognitive profile and engages them in a reflective dialogue. In this paper we present the application of ReTuDiS for computer network text comprehension. Learners participate in a reflective dialogue concerning computer network topology. The d...

Reflective portfolios are a collection of evidence that through critical reflection on its contents demonstrate achievement as well as personal and professional development. The purpose of this paper is to provide a review of the literature on the use of reflective portfolios and to develop a set of factors to guide schools and colleges of pharmacy as they implement reflective portfolios into t...

Nowadays, middleware technologies are the main infrastructure to support component-based programming. To meet the dynamic configuration requirements of several application classes, middleware systems like CORBA and DCOM provide some reflective mechanisms, such as interface introspection, dynamic dispatching, and message interceptors. Recent evolution of CORBA and DCOM emphasizes the importance ...

BACKGROUND Teacher feedback on student reflective writing is recommended to improve learners' reflective competence. To be able to improve teacher feedback on reflective writing, it is essential to gain insight into which characteristics of written feedback stimulate students' reflection processes. Therefore, we investigated (1) which characteristics can be distinguished in written feedback com...

The overhead incurred by reasoning in knowledge-based systems can be considerable when it is forced to rely on search. Even problems that are known to have tractable solutions can expend large amounts of computation when the inference method is too general. As discussed in this paper, reflective ar-chitectures provide a well-motivated framework for integrating specialized control with general r...

Systems development research shows that practitioners seldom follow methods and that the competencies required for successful development of computer-based systems go well beyond those represented in contemporary methods. These insights make us question the role that methods should play in educating would-be developers. Pedagogical theories, such as situated learning and double-loop learning, c...

Qualitative research comes with various forms and faces, and, fortunately, there now exist numerous books that deal with issues related to qualitative research. Not that many books, however, deal explicitly and extensively with the transformation and application of principles of phenomenology and hermeneutics. Reflective Lifeworld Research is written as a response to this apparent need. It is, ...

A competent system need not be perfect. It should not try to solve unsolvable problems. Rather it should simplify and decompose overcomplex problems, complement missing information, weight the quality of a solution against the cost of achieving it, approximate solutions if time is sparse, etc. To make a knowledge-based system more competent, we propose to enhance it by suitable competence speci...

Middleware platforms and related services form a vital cog in the construction of robust distributed systems. Middleware facilitates the development of large software systems by relieving the burden on the applications developer of writing a number of complex infrastructure services needed by the system; these services include persistence, distribution, transactions, load balancing, clustering,...
