Hence, optimizing production by exploiting the reusability of interactive multimedia elements is mandatory. Reusability can be triggered by a combination of resuable multimedia components and the appropriate use of metadata to control the components as well as their combination. In this article, we discuss the reusability aspects of interactive multimedia content in web-based learning systems. In contrast to existing approaches, we extend a component-based architecture to build interactive multimedia visualization units with the use of metadata for reusability and customizability. In the three-tier model, the lowest layer of the paradigm corresponds to the programmer (code reusability). The user interface of an educational visualization is located at the top layer where the interaction with the end-user (student) takes place. The educator is located between the top and the bottom layers. This medium layer allows adapting interactive multimedia content according to the needs of the user, applying a predefined set of metadata. The teacher can both adjust the level of explanation and the level of interactivity of an animation, and influence the presentation and the results of the algorithms being illustrated (program reusability). After a theoretical overview, we explain our architecture by giving an example of an application.</description> <keywords>Design</keywords> <keywords>Theory</keywords> </general> <lifecycle> <status>Final</status> <contribute> <role>Author</role> <entity> BEGIN:vCard FN:Abdulmotaleb El Saddik N:El Saddik;Abdulmotaleb EMAIL;INTERNET:- END:vCard </entity> <date datetype="datetime"> 2001-08-21 </date> </contribute> <contribute> <role>Author</role> <entity> BEGIN:vCard FN:Stephan Fischer N:Fischer;Stephan EMAIL;INTERNET:- END:vCard </entity> <date datetype="datetime"> 2001-08-21 </date> </contribute> <contribute> <role>Author</role> <entity> BEGIN:vCard FN:Ralf Steinmetz N:Steinmetz;Ralf EMAIL;INTERNET:- END:vCard </entity> <date datetype="datetime"> 2001-08-21 </date> </contribute> </lifecycle> <metametadata> <contribute> <role>Contributor</role> <entity> BEGIN:vCard FN:Hussein Suleman N:Suleman;Hussein EMAIL;INTERNET:hussein@vt.edu ORG:; END:vCard </entity> <date datetype="datetime"> 2001-08-21 </date> </contribute> <language>en-US</language> </metametadata> <technical> <format>text/html</format> <location>http://www.cstc.org/cgi-bin/show_abstract.pl?type=official&number=158</location> </technical> <educational> <intendedenduserrole>Learner</intendedenduserrole> <intendedenduserrole>Teacher</intendedenduserrole> <learningcontext>Higher Education</learningcontext> <learningcontext>Secondary Education</learningcontext> </educational> <classification> <purpose>Educational Objective</purpose> <taxonpath> <source>ACM Computer Science Curriculum</source> <taxon> <entry>Software Methodology and Engineering</entry> </taxon> </taxonpath> <description>The type of class that this resource is best suited for</description> </classification> <classification> <purpose>Discipline</purpose> <taxonpath> <source>ACM Computing Classification System</source> <taxon> <entry>Information Systems</entry> </taxon> <taxon> <entry>Information Interfaces and Presentation</entry> </taxon> </taxonpath> <description>The subject classification that best describes the resource</description> </classification> <classification> <purpose>Discipline</purpose> <taxonpath> <source>ACM Computing Classification System</source> <taxon> <entry>Computing Milieux</entry> </taxon> <taxon> <entry>Computers and Education</entry> </taxon> </taxonpath> <description>The subject classification that best describes the resource</description> </classification> </oai_ims> </metadata> </record> <record> <header> <identifier>oai:CSTC:103</identifier> <datestamp>2001-09-06</datestamp> </header> <metadata> <oai_ims xmlns="http://oai.dlib.vt.edu/metadata/oai_ims" xsi:schemaLocation="http://oai.dlib.vt.edu/metadata/oai_ims http://oai.dlib.vt.edu/OAI/oai_ims.xsd"> <general> <title>Turing Machine Applet</title> <catalogentry> <catalogue>CSTC</catalogue> <entry>103</entry> </catalogentry> <description> The following Java applet animates a Turing Machine that can add or multiply numbers.

The 3.1 version of JFLAP is written in Java using JDK 1.2 and JDK 1.1.5 and contains several new features and bug fixes. Using JFLAP, one should be able to design and simulate several variations of finite automata (FA), pushdown automata (PDA), one-tape Turing machines (TM) and two-tape Turing machines (TTM). The user draws the transition diagram of the desired automaton and, once the picture is complete, the user enters an input string and then "runs" the automaton, being able to view all the generated configurations. In addition, JFLAP can handle grammars(GRM) and regular expressions(REX).</description> <keywords>finite automata</keywords> <keywords>pushdown automata</keywords> <keywords></keywords> <keywords>formal langauges</keywords> <keywords>automata theory</keywords> </general> <lifecycle> <status>Final</status> <contribute> <role>Author</role> <entity> BEGIN:vCard FN:Susan Rodger N:Rodger;Susan EMAIL;INTERNET:rodger@cs.duke.edu END:vCard </entity> <date datetype="datetime"> 1999-09-22 </date> </contribute> </lifecycle> <metametadata> <contribute> <role>Contributor</role> <entity> BEGIN:vCard FN:Susan Rodger N:Rodger;Susan EMAIL;INTERNET:rodger@cs.duke.edu ORG:Duke University;Computer Science END:vCard </entity> <date datetype="datetime"> 1999-09-22 </date> </contribute> <language>en-US</language> </metametadata> <technical> <format>text/html</format> <location>http://www.cstc.org/cgi-bin/show_abstract.pl?type=official&number=72</location> <requirements> <type>Platform</type> <name>Java Virtual Machine</name> </requirements> <requirements> <type>Operating System</type> </requirements> <requirements> <type>Programming Language</type> <name>Java</name> </requirements> </technical> <educational> <intendedenduserrole>Learner</intendedenduserrole> <intendedenduserrole>Teacher</intendedenduserrole> <learningcontext>Higher Education</learningcontext> <learningcontext>Secondary Education</learningcontext> </educational> <classification> <purpose>Educational Objective</purpose> <taxonpath> <source>ACM Computer Science Curriculum</source> <taxon> <entry>Programming Languages</entry> </taxon> </taxonpath> <description>The type of class that this resource is best suited for</description> </classification> <classification> <purpose>Discipline</purpose> <taxonpath> <source>ACM Computing Classification System</source> <taxon> <entry>Theory of Computation</entry> </taxon> <taxon> <entry>General</entry> </taxon> </taxonpath> <description>The subject classification that best describes the resource</description> </classification> <classification> <purpose>Discipline</purpose> <taxonpath> <source>ACM Computing Classification System</source> <taxon> <entry>Software</entry> </taxon> <taxon> <entry>Programming Languages</entry> </taxon> </taxonpath> <description>The subject classification that best describes the resource</description> </classification> </oai_ims> </metadata> </record> <record> <header> <identifier>oai:CSTC:105</identifier> <datestamp>2001-09-06</datestamp> </header> <metadata> <oai_ims xmlns="http://oai.dlib.vt.edu/metadata/oai_ims" xsi:schemaLocation="http://oai.dlib.vt.edu/metadata/oai_ims http://oai.dlib.vt.edu/OAI/oai_ims.xsd"> <general> <title>Pentium III and Pentium Pro Microprocessor</title> <catalogentry> <catalogue>CSTC</catalogue> <entry>105</entry> </catalogentry> <description> The following Java applet animates the hardware signal timing used in various bus operations by Pentium III and Pentium Pro microprocessors.

It simulates the one dimensional discrete cosine transform and the one dimensional discrete Fourier transform. Both transforms are a basis for modern signal processing algorithms like the JPEG image compression standard. When confronted with the mathematical formulas, most students show difficulties in understanding the notion of "time domain" and "frequency domain", or of "superposition of different frequencies". The applet simulates the transformation of a 1 dimensional signal. The amplitudes of the different frequency components can be modified, and the effect on the signal will get clearer. The user interface of the applet has been built to stimulate the user to play around with the tool. The applet is highly interactive and very flexible. One can choose between a number of given input signals or the user can build a signal by himself. Of course, a solution for every input is provided.</description> <keywords>Applet</keywords> <keywords>Simulation</keywords> <keywords>1-D DCT</keywords> <keywords>1-D DFT</keywords>

DCT</title> <catalogentry> <catalogue>CSTC</catalogue> <entry>100</entry> </catalogentry> <language>English</language> <description> This applet visualizes the 2 dimensional DCT as it is used in the JPEG compression standard. Also, most of the Internet compressions standards for video (Motion JPEG, H.261, H.263) are based on the Discrete Cosine Transform (DCT) which splits an image up into blocks of 8x8 pixels. Our applet tries to clear out the problems with the 2 dimensional DCT by invoking the "play instinct" of students: The user can chose discrete 8x8 (2-D) input values in the range 0 to 255 for the grey value of the pixels. In the frequency domain, rulers allow to adjust the amplitudes of the different frequencies. A backward transform plots the resulting grey values from the chosen ampitudes over the initial input values. The task is to find the "correct" amplitudes in the frequency domain to recover the initial signal. Of course, we have included a solution to the problem...</description> <keywords>simulation</keywords> <keywords>signal processing</keywords> <keywords>2-dimensional DCT</keywords> </general> <lifecycle> <status>Final</status> <contribute> <role>Author</role> <entity> BEGIN:vCard FN:Holger Wons N:Wons;Holger EMAIL;INTERNET:holger.wons@gmx.de END:vCard </entity> <date datetype="datetime"> 2001-10-29 </date> </contribute> <contribute> <role>Author</role> <entity> BEGIN:vCard FN:Claudia Schremmer N:Schremmer;Claudia EMAIL;INTERNET:schremmer@informatik.uni-mannheim.de END:vCard </entity> <date datetype="datetime"> 2001-10-29 </date> </contribute> </lifecycle> <metametadata> <contribute> <role>Contributor</role> <entity> BEGIN:vCard FN:Claudia Schremmer N:Schremmer;Claudia EMAIL;INTERNET:schremmer@informatik.uni-mannheim.de ORG:University of Mannheim;Praktische Informatik IV END:vCard </entity> <date datetype="datetime"> 2001-10-29 </date> </contribute> <language>en-US</language> </metametadata> <technical> <format>text/html</format> <location>http://www.cstc.org/cgi-bin/show_abstract.pl?type=official&number=100</location> <requirements> <type>Platform</type> <name>HTML Browser, Java Virtual Machine</name> </requirements> <requirements> <type>Operating System</type> <name>All</name> </requirements> <requirements> <type>Programming Language</type> <name>HTML, Java</name> </requirements> </technical> <educational> <intendedenduserrole>Learner</intendedenduserrole> <intendedenduserrole>Teacher</intendedenduserrole> <learningcontext>Higher Education</learningcontext> <learningcontext>Secondary Education</learningcontext> </educational> <classification> <purpose>Educational Objective</purpose> <taxonpath> <source>ACM Computer Science Curriculum</source> <taxon> <entry>Algorithms and Data Structures</entry> </taxon> </taxonpath> <description>The type of class that this resource is best suited for</description> </classification> <classification> <purpose>Discipline</purpose> <taxonpath> <source>ACM Computing Classification System</source> <taxon> <entry>Data</entry> </taxon> <taxon> <entry>Coding and Information Theory</entry> </taxon> </taxonpath> <description>The subject classification that best describes the resource</description> </classification> <classification> <purpose>Discipline</purpose> <taxonpath> <source>ACM Computing Classification System</source> <taxon> <entry>Theory of Computation</entry> </taxon> <taxon> <entry>Miscellaneous</entry> </taxon> </taxonpath> <description>The subject classification that best describes the resource</description> </classification> <classification> <purpose>Discipline</purpose> <taxonpath> <source>ACM Computing Classification System</source> <taxon> <entry>Mathematics of Computing</entry> </taxon> <taxon> <entry>Miscellaneous</entry> </taxon> </taxonpath> <description>The subject classification that best describes the resource</description> </classification> </oai_ims> </metadata> </record> <record> <header> <identifier>oai:CSTC:108</identifier> <datestamp>2001-09-06</datestamp> </header> <metadata> <oai_ims xmlns="http://oai.dlib.vt.edu/metadata/oai_ims" xsi:schemaLocation="http://oai.dlib.vt.edu/metadata/oai_ims http://oai.dlib.vt.edu/OAI/oai_ims.xsd"> <general> <title>Altair Emulator</title> <catalogentry> <catalogue>CSTC</catalogue> <entry>108</entry> </catalogentry> <language>English</language> <description> This is a very well done emulator of the Altair 8800b</description> <keywords>Altair emulator 8800</keywords> </general> <lifecycle> <status>Final</status> <contribute> <role>Author</role> <entity> BEGIN:vCard FN:Claus Giloi N:Giloi;Claus EMAIL;INTERNET:clausgi@microsoft.com END:vCard </entity> <date datetype="datetime"> 2001-09-06 </date> </contribute> </lifecycle> <metametadata> <contribute> <role>Contributor</role> <entity> BEGIN:vCard FN:Mike Belanger N:Belanger;Mike EMAIL;INTERNET:mbelange@vt.edu ORG:;

Designed and built at Cambridge University, England, the EDSAC performed its first calculation on 6 May 1949. The Edsac simulator is a faithful software evocation of the EDSAC computer as it existed in 1949-51. The user interface has all the controls and displays of the original machine, and the system includes a library of original programs, subroutines, and debugging software. The simulator is intended for use in teaching the history of computing; as a tutorial introduction to the classic "von Neumann" computer; or as an historical experience for current computer

The focus of the system is on ease-of-use. XTANGO utilizes the path-transition animation paradigm which helps move animation design to an abstract, high level. Programmers need not be graphics experts to develop their own animations. XTANGO is implemented on top of UNIX and the X11 Window System.

Each version uses the same abstract model to represent the state of an undirected graph and the same kernel operations to manipulate the state of that undirected graph. The implementation strategy changes for each version. The first five versions utilize the "classic" strategies (adjacency list, adjacency matrix, and edge list) in a variety of ways.

By modifying this specification and observing the resulting behavior, teaching and learning in a constructive manner is enabled. The framework is open to plug-in tools to show various aspects of HiSAP's behavior.

There are many variations to this problem, including inclusion of faculty constraints, room constraints, and multiple sections. The problem is known to be NP-Complete, thus many researchers have worked on approximation solutions to the problem. Researchers have generally focused on one solution method, one unique version of the problem definition, and one set of data based on local needs. This localization of the problem has resulted in many studies but no general consensus of the best method available. In this study, we explore several methods from the literature on a single definition of the problem, and on a common set of data. Our goals are two-fold. First, we provide a problem statement, data, and a random data generator to facilitate easy benchmarking of methods and techniques. Second, we explore the best method for those who may be non-experts and need to schedule courses. Background and Related Work While a great deal of research has been done on scheduling methods, our study concentrates on two of the most promising efforts: iterative improvement and linear programming. Iterative improvement methods for scheduling including faculty constraints have been studied in particular by Glover [3], and Chahal and DeWerra [1]. Hertz's use of Tabu search considers many different constraints [4]; we have adopted many of these constraints in our benchmark formulation of the problem. Our modification to the problem and our new data provides a different testbed for this algorithm and allows it to be compared against other methods. Linear programming allows one to formulate an equation for the optimal solution to the problem; practical solutions involving this method are infrequent [2], and do not consider many of the constraints we consider. Approach and Uniqueness We address the problem of comparing results from the literature in two ways. First, we define one statement of the course scheduling problem, involving faculty, students, and multiple sections, and adapt several of the approaches from the literature to this problem. Thus, any comparison of the approaches will start from the same problem definition. Second, we provide a random data generator that generates student course requests in such a way that an optimal solution must exist. Finally, we have studied five methods for course scheduling in our study: A greedy algorithm that simply schedules courses to the first available time (results from this simple method give some idea as to the usefulness of more complex methods), iterative improvement algorithms following a hill-climbing philosophy and following a "random improvement" philosophy in which a solution with a poorer evaluation may be used to continue the search for an improved solution, linear programming, and an algorithm that creates a bipartite matching problem for scheduling each student based on the times available for each course requested. Our formulation of the course scheduling problem used is as follows: We are given information about the courses (number of sections, faculty members teaching the course, times at which the course can be taught), lists of desired student courses, and the number of timeslots in which to schedule the courses. Courses are grouped into departments and for each department we have information on how many courses from that department may be scheduled concurrently (representing room availability constraints). The goal of the problem is to build a timetable and schedule for students' courses minimizing student conflicts while satisfying constraints on faculty and room availability. This study provides a repeatable and expandable comparison of scheduling methods. The algorithms were tested on random data and on data from a DIMACS benchmark for graph coloring that involves course scheduling. The generator and benchmark data are publically available, thus other methods can be tested on the same or very similar data. Results and Contributions We have developed a data generator that generates student course requests given the description of a timetable (the number of courses in the table, and the number of sections of each course), the section bound for each course, and the number of schedules desired. The generator builds a random timetable, and then generates student course requests using a backtracking technique that ensures the student can get each course requested. Information on which section the student would attend and the time of each course is stripped from the data so the data appears real to the algorithms. We conducted a study of the methods described above on thirteen sets of randomly generated data. Each method was run five times and we used the median to compare how close each method comes to scheduling courses optimally. (The Linear Programming method could not be tested because our formulation resulted in so many variables that our machines ran out of memory.) We have drawn the following conclusions from our empirical study. First, the greedy algorithm is not competitive with other approximation methods, meaning the time spent developing and using these methods is worthwhile. Second, iterative improvement is currently the best practical method for course scheduling when the courses have only a single section each. Third, when courses have multiple sections each, bipartite matching is very competitive with the iterative improvement algorithms while running much faster. References [1] N. Chahal and D. deWerra.

Sequencing can help to generate hypermedia documents which, at their best match the learner's needs. To perform (semi-) automatic course sequencing, a knowledge library as well as modular resources can be used. Both must be described by metadata.</p> <p>First, metadata standards (IEEE Learning Objects Metadata, Instructional Mangement Systems Global Learning Consortium, Dublin Core) are analyzed with regard to course sequencing. As an application example, Multibook, an adaptive hypermedia system used to teach multimedia technology, is described. Multibook uses metadata to create course sequences semi-automatically. In this article we explain how a knowledge library can be used to create exercises automatically. We give an example of how courses can be sequenced in general by analyzing the creation of exercises. An evaluation of our system shows the advantages and drawbacks of the automatic sequencing approach.</p></description> <keywords>Documentation</keywords> <keywords>Management</keywords> </general> <lifecycle> <status>Final</status> <contribute> <role>Author</role> <entity> BEGIN:vCard FN:Stephan Fischer N:Fischer;Stephan EMAIL;INTERNET:- END:vCard </entity> <date datetype="datetime"> 2001-08-21 </date> </contribute> </lifecycle> <metametadata> <contribute> <role>Contributor</role> <entity> BEGIN:vCard FN:Hussein Suleman N:Suleman;Hussein EMAIL;INTERNET:hussein@vt.edu ORG:; END:vCard </entity> <date datetype="datetime"> 2001-08-21 </date> </contribute> <language>en-US</language> </metametadata> <technical> <format>text/html</format> <location>http://www.cstc.org/cgi-bin/show_abstract.pl?type=official&number=159</location> </technical> <educational> <intendedenduserrole>Learner</intendedenduserrole> <intendedenduserrole>Teacher</intendedenduserrole> <learningcontext>Higher Education</learningcontext> <learningcontext>Secondary Education</learningcontext> </educational> <classification> <purpose>Educational Objective</purpose> <taxonpath> <source>ACM Computer Science Curriculum</source> <taxon> <entry>Database and Information Retrieval</entry> </taxon> </taxonpath> <description>The type of class that this resource is best suited for</description> </classification> <classification> <purpose>Discipline</purpose> <taxonpath> <source>ACM Computing Classification System</source> <taxon> <entry>Information Systems</entry> </taxon> <taxon> <entry>Information Interfaces and Presentation</entry> </taxon> </taxonpath> <description>The subject classification that best describes the resource</description> </classification> <classification> <purpose>Discipline</purpose> <taxonpath> <source>ACM Computing Classification System</source> <taxon> <entry>Computing Milieux</entry> </taxon> <taxon> <entry>Computers and Education</entry> </taxon> </taxonpath> <description>The subject classification that best describes the resource</description> </classification> </oai_ims> </metadata> </record> <record> <header> <identifier>oai:CSTC:160</identifier> <datestamp>2001-08-21</datestamp> </header> <metadata> <oai_ims xmlns="http://oai.dlib.vt.edu/metadata/oai_ims" xsi:schemaLocation="http://oai.dlib.vt.edu/metadata/oai_ims http://oai.dlib.vt.edu/OAI/oai_ims.xsd"> <general> <title>Using a theoretical multimedia taxonomy framework</title> <catalogentry> <catalogue>CSTC</catalogue> <entry>160</entry> </catalogentry> <language>English</language> <description> <P>Multimedia (MM) is a polysemous term, a term with many definitions, and in this case, many roots. In this paper, multimedia is defined as the seamless integration of two or more media. Each ancestor brings another requirement, muddying the field and making it difficult to work through. A multimedia taxonomy based on a previous media taxonomy is proposed to help organize the discipline. The taxonomy helps to classify the space called multimedia and to draw attention to difficult issues. The paper outlines the forms contributing to multimedia--text, sound, graphics, and motion--and aligns them with probable formats--elaboration, representation, and abstraction-- and sets them within a context--audience, discipline, interactivity, quality, usefulness, and aesthetics. The contexts are more clearly defined in two areas: interactivity and the information basis for a discipline. Examples are presented describing the use of the taxonomy in the design and evaluation of student projects in a computer science-based multimedia course.<p></description> <keywords>computer uses in education</keywords> <keywords>evaluation</keywords> <keywords>multimedia</keywords> <keywords>design</keywords> <keywords>theory</keywords> </general> <lifecycle> <status>Final</status> <contribute> <role>Author</role> <entity> BEGIN:vCard FN:Rachelle S.
