Diagrammatic Representations

Articulating thought in computer-based media is a powerful means for humans to develop their understanding of phenomena. We have created DynaLearn, an Intelligent Learning Environment that allows learners to acquire conceptual knowledge by constructing and simulating qualitative models of how systems behave. DynaLearn uses diagrammatic representations for learners to express their ideas. The environment is equipped with semantic technology components capable of generating knowledge-based feedback, and virtual characters enhancing the interaction with learners. Teachers have created course material, and successful evaluation studies have been performed. This article presents an overview of the DynaLearn system.

Effective Use

A review of multiple online courses at one institution was conducted by a skilled screen reader user for the purpose of assessing the extent to which the courses were navigable and understandable to online students using assistive technologies. This paper identifies features of online courses that may present problems for screen reader users and recommends solutions to address those problems. The following two overarching recommendations are suggested and elaborated: 1) Just as a roadmap assists drivers in navigating unfamiliar terrain, principles of clarity, consistency, and organization should be applied to the design of online courses to orient students to the virtual learning environment. 2) Web pages and course documents should make effective use of metadata, i.e., machine-understandable information about computer-based content, in order for course material to be accurately understood by students using a screen reader.

The goal of the study in this chapter is to support learners to engage in the active learning of common fraction operations from the constructivists’ perspective. An Internet-based Fraction-learning Intelligent Learning Environment (IFILE) is designed under the knowledge-based approach to model the learning process of the target topic. It is intended to optimize the interaction opportunity of learners by providing pedagogical tools and intelligent features. The two pedagogical tools provided are graphical support and electronic blank sheet. The intelligent feature discussed in this chapter is the Next Step Support for helping learners to break the impasse in fraction operations. The key activity of the construction of the Next Step Support of this knowledge-based application is designing rules as embedded units to sense and react to all facets of the fraction evaluation process. This chapter discusses further how the IFILE is designed for developing learning properties from the constructivists’ standpoint.

This paper presents the first step in the development of a new kind of computer-based tool which can help a specialist consultant in avalanche path analysis, a knowledge-based or expert system. In considering an avalanche path, the specialist often needs a simulation of possible avalanches on this path in order to obtain data for probable velocities and pressures. Use of classical numerical tools by an engineer requires a great deal of experience and knowledge. Such knowledge exists, but until the development of knowledge-based systems no computer-based tool was available. After a short review of such systems, we describe a knowledge-based system currently being developed in CEMAGREF. Its problem-solving environment includes methods of analysis developed by a senior consultant, and also numerical and qualitative models. In the first step, which is presented here, it analyses the starting zone of an avalanche path. By means of a digital terrain model and a description of vegetation and main ridges (a model which still needs to be improved) this system can make use of the experience of specialists to produce an avalanche-starting simulation based on specified meteorological conditions. Quite simple rules are employed in order to take into account snow drift. First results are shown on accompanying maps of this qualitative modelling and these will need to be tested for validity.

The reception of journalists at the Waspada Daily Medan always went through several rigorous selections before being determined to be accepted as journalists at the Waspada Medan Daily. There are several criteria that must be possessed by each participant as a condition for becoming a journalist in the Daily Alert Medan. To get the best participants, the Waspada Medan Daily needed a decision support system. Decision Support Systems (SPK) are part of computer-based information systems (including knowledge-based systems (knowledge management)) that are used to support decision making within an organization or company. Decision support systems provide a semitructured decision, where no one knows exactly how the decision should be made. In this study the authors applied the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) as the method to be applied in the decision support system application. The VIKOR method is part of the Multi-Attibut Decision Making (MADM) Concept, which requires normalization in its calculations. The expected results in this study can obtain maximum decisions.Keywords: Journalist Acceptance, Decision Support System, VIKOR

This chapter investigates how platformization is affecting the idea of education as a common good on both sides of the Atlantic. The growth of online educational platforms has been explosive, in both primary and higher education. Most of these educational platforms are corporately owned, propelled by algorithmic architectures and business models. They have quickly gained millions of users and are altering learning processes and teaching practices; they boost the distribution of online course material, hence impacting curriculums; they influence the administration of schools and universities; and, as some argue, they change the governance of (public) education as a whole. The chapter explores how, powered by the Big Five, these educational platforms are pushing a new concept of learning that questions values that are fundamental to publicly funded education: Bildung, a knowledge-based curriculum, autonomy for teachers, collective affordability, and education as a vehicle for socioeconomic equality.

The Chinese government is pursuing e-learning policies which makes job-training with a knowledge-based society. To explain more fully the important role of the e-learning environment, this article undertakes some typical examples of the governments' job-training under e-learning environment. The main problems in servants' job-training in China are the low quantity in the servants' training, short of restriction, the uniform manner in the training and less fairness and availability of opportunities for educational training. In order to develop the e-learning system, the civil servant's job training policies are provided and the measures of the effective e-learning system are designed.
