"Even with this developing knowledge, the application of screw propulsion to boats could not take place until the advent of steam power. Due to greater suitability with the slow-turning, early steam engines, the first powerboats used paddle wheels for a form of water propulsion. In 1660, Toogood and Hays adopted the Archimedean screw as a ship propeller. Even by the 19th century, screw propulsion was still

Computer Renderings ? ?Reality is Overrated?
In this paper, two problems concerning truthfulness of computer-generated visualization are considered. The first one concerns relationships between reality and its representation by computer renderings. The second problem concerns the kind of representations people need. These problems are analyzed for static perception of architectural forms based on computer visualization, and for dynamic walk-through perception of urban space. The thesis of the paper is that many photorealistic renderings ar
ICT-enhanced Teacher training for Lifelong Competence
Development
In this paper we are giving an example of how Information and Communication Technologies
(ICT) can enhance the process of Teacher training, and how this can be used for Lifelong
Competence Development of teachers. We show how one particular methodology for teaching
and training soft skills can be further enhanced by the use of ICT. We show how the use of
Learning Design centred software platform for lifelong competence development can enhance
the in-service training of teachers.
Theories of Public Policy
This course examines competing theories, models, and analytical frameworks for understanding policymaking. Case study application is used to underscore lessons learned. Knowledge of the basic tools of lawmaking is sharpened. The course is taught as a seminar and students are expected to participate actively in class discussion.

The First Decade of Informatics in Dutch High Schools
Informatics is currently being taught in high schools all over the world. In the Netherlands, where all students are expected to become computer literate in the lower grades of high school (Hulsen et al., 2005), it has been decided not to consider computer literacy as being part of Informatics. What, then, should be the content of the Informatics curriculum taught in the higher grades? What should be taught, how and to whom? How should students' achievements be assessed? The answers to these que
Patchworking as a Metaphor for Learning –
Understanding youth, learning and technology
On basis of a close empirical examination of a Danish team of 'Power Users' and their work on a self-chosen learning challenge this thesis argues how we can theoretically understand, analyse and methodologically approach learning processes through the metaphorical lens of ‘patchworking’.
The metaphor of patchworking highlights how
learning processes can be seen as processes of stitching and weaving together different ‘patches and pieces’ into something new. The patches and pieces may not

CONCEPTUAL KMS ARCHITECTURE WITHIN ENTERPRISE 2.0 AND CLOUD COMPUTING
Today, the adoption of Enterprise 2.0 is not an option, but a must for knowledge-based organizations within the changing social paradigms. The new-coming generation of employees and customers expect technological proficiency to be part of the customer-centered business models. On their turn, organizations need to apply new forms of cooperation with their employees, customers, suppliers and partners. The knowledge is recognized as crucial resource and its efficient management determines sustainab

The goal of this paper is to explore extensions to electronic dictionaries. Adding certain functions could considerably extend the range of tasks for which they could provide support. Putting the needed information at the distance of a mouse click would allow for active reading. This would require tight coupling of the dictionary with a text editor: all the information in the dictionary should be accessible via a mouseclick. Dictionaries combined with a flashcard system and an exercise generator
“Cultures in negotiation”: teachers’ acceptance/resistance attitudes considering the infusion of
A teachersÂ’ training project, employing teacher-mentored in-school training approach, has been recently initiated in Greek secondary education for the introduction of Information and Communication Technology (ICT) into the classroom. Data resulting from this project indicate that although teachers express considerable interest in learning how to use technology they need consistent support and extensive training in order to consider themselves able for integrating it into their instructional pra

A learning environment for the Teaching of the Natural Sciences in the 6th grade of Primary school will be presented. The learning environment combines the use of new technologies with collaborative learning. It has been based on general learning principles derived from research on the fields of Psychology and Physics Education. The effects of the learning environment on the studentsÂ’ cognitive, metacognitive and cooperative performance have been thoroughly studied through the use of various me
Using visualizations to teach problem-solving skills in mathematics: Which kind of visualization wor
In the experiment described in this paper we investigated the effects of different kinds of computer-based visualizations on the acquisition of problem-solving skills in the domain of probability theory. Learners received either purely text-based worked examples, text plus an instruction to mentally imagine the examplesÂ’ contents, or they could retrieve either static pictures or concrete animations that depicted the problem statement and the problem states achieved by applying a specific solut
A methodological alternative to media comparison studies: Linking information utilization strategies
Literature reviews on hypermedia learning have yet failed to show consistent positive effects of learner-controlled nonlinear information access. We argue that a possible reason for this lack of evidence in favor of hypermedia learning results from the fact that not sufficient attention is paid to the strategies of information utilization learners deploy. The few studies that do analyze these strategies fail to link them to an instructional approach, which hampers a deeper interpretation of stra
The impact of example comparisons on schema acquisition: Do learners really need multiple examples?
Comparing multiple examples within problem categories is usually considered a necessary prerequisite for schema acquisition. However, there is an evident lack of conclusive empirical evidence supporting this claim. Moreover, there are findings indicating that carefully designed one-example conditions may allow for profitable processes of example comparison as well. In line with this reasoning, we present an experiment - that builds up on a series of studies conducted by Quilici and Mayer (1996)
Cognitive tools for discovery learning
Cognitive tools, defined here as instruments that support or perform cognitive processes for learners in order to support learning, can bridge the difference between open learning environments, like discovery learning environments and traditional supportive instructional environments. This article discusses a definition of the concept of cognitive tool and its use in learning. Two examples of cognitive tools for discovery environments are presented, and it is made clear how these tools can serve
