The main aim of this study is to integrate cooperative learning strategies, mastery learning and interactive multimedia to improve students’ performance in Mathematics, specifically in the topic of matrices. It involved a quasi-experimental design with gain scores and time-on-task as dependent variables. The independent variables were three instructional strategies (CCL, CML and CCML) with acad...

In this paper we introduce the Crayon Co-Create (CCreate) drawing tool as a mixed-initiative design approach for fostering the creativity of young learners. CCreate follows the principles of mixed-initiative iterative design utilizing variants of novelty search for generating abstract drawings that act as a visual disruptor during the creation process. The authoring tool finds a multitude of us...

The techniques described here can be used for beam line design in quite general circumstances. We are introducing them for a final focus system design in linear col_ . liders because this is where we have applied them, and to provide a specific context for our discussion. Other optical systems may require modifications or extensions to the methods we introduce here. We have kept the formalism a...

Web authoring and publishing has become a daily task for almost every enterprise or organization. One big question is how the Web authoring and publishing can be organized or coordinated in such a way that contents provided by qualified staffs, information architecture designed by information specialists and professional design made by specialists can be integrated together perfectly to build a...

Electronic books are not yet heavily used because they still do not offer sufficient benefits. The Slicing Book approach is a new approach to electronic books offering personalized electronic textbooks for learners. Books are split into slices and the logical relationship between those slices is made explicite, e.g. what slice builds on knowledge provided by what other slices. This knowledge ca...

This article presents the functional architecture and the interaction model of GENITOR, a generator of Intelligent Tutoring Systems (ITSsj. The major design issues that arise during the functional design and development of an ITS-generator concern the provision of mechanisms capable of supporting the description of the teaching subject domain and the specification of pedagogical features of the...

The characterization of and construction of a new optical sensor based on the immobilization of Pyrocatechol Violet on a triacetylcellulose membrane was described to for the determination of bismuth (III) in real samples. The interaction between sensing membrane and bismuth (III) was caused at pH 3.80 in acetate buffer solution and the color changed from yellow to blue along with the appearance...

DESIGN OF ROUTERS FOR OPTICAL BURST SWITCHED NETWORKS by Jeyashankher Ramamirtham ADVISOR: Professor J. Turner August, 2004 Saint Louis, Missouri Optical Burst Switching (OBS) is an experimental network technology that enables the construction of very high capacity routers using optical data paths and electronic control. In this dissertation, we study the design of network components that are n...

Considering the benefits of Quantum and Optics, if the logic gates in the quantum field and electronic structure are implemented using optical elements, then it will be benefited from advantages of Quantum and design, and these processing circuits can be used in optical computing and quantum computing, genetic processes, and other useful nanotechnology applications. In this study, we have intro...
