      <description> This tool uses JavaScript to implement a number system conversion tool that can be used to teach the concepts of different number systems as part of an introductory math or computer science course. Users can convert numbers from decimal to another base, and from other bases to decimal, and the conversion process is explained.
There is also a quiz feature which allows students to test their ability to convert numbers on their own.</description>

      <title>Reusability and adaptability of interactive resources in web-based educational</title>

      <description> The production of interactive multimedia content is in most cases an expensive task in terms of time and cost. 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>

      <description> In the described laboratory assignment, the mechanism of the sparse matrix
is an array (row index) of linked lists storing only the nonzero values
within a row, together with the column index of the saved element. The
educational goals of the described lab are to (1) gain appreciation of,
and experience with, a layered approach to the implementation of a
relatively complex structure; (2) stress the distinction and separation
between the public interface (as seen by the client, or user of a class)
and the implementation; and (3) stress the importance of designing a
clear, complete, and intuitive public interface to a class.</description>

      <description> These Java applets are used for studying distributed algorithms. They presume familiarity with distributed algorithms. The applets are not simple animations where you passively watch the algorithm. Instead, they are interactive, visual, study aids for studying distributed algorithms.</description>

      <description> This lab introduces students to the use of classes in C++.
By the end of the lab, students will know how to declare a class,
how to define member functions, and how to test member functions.
This lab involves a C++ console program. It was developed to run
on a PC using Microsoft Visual C++ 5.0, but any C++ compiler
will work. The lab can be completed in one class session, about
75 minutes.</description>

      <description> JFLAP is a package of graphical tools which can be used as an aid in learning the basic concepts of Formal Languages and Automata Theory. 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>

      <description> This applet belongs to the context of Multimedia or Signal Procesing. 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>

      <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>

      <description> The EDSAC was the world's first stored-program computer to operate a regular computing service. 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 practitioners.</description>

      <description> The above Java Applet simulates a simple computer consisting of 32 8 bit memory words. The computer operates by fetching a word in memory pointed to by the Program Counter (PC) into the Instruction Register (IR)and then executing this instruction. The Program Counter is then incremented by one and the process is repeated until a Halt instruction is fetched at which time the computer stops and the binary number in the Accumulator (ACC)can be read.</description>

      <description> This is a quite complicated applet/servlet combination to interactively animate almost any Java application or algorithm. The basic idea is to animate user's code interactively. First You write the code, send it to the server and wait a while. Then You can watch Your own code in action. The system is able to animate almost any algorithm written in Java, exact details of the restictions can be found in the user's manual. Major features: user's own code (with or without errors :), interactive, line-by-line</description>

      <description> XTANGO is a general purpose algorithm animation system, developed by John Stasko of Georgia Tech, that supports programmers developing color, real-time, 2 &amp; 1/2 dimensional, smooth animations of their own algorithms and programs. 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. It can be run on either color or black-and-white monitors.</description>

      <title>A New and More Efficient Implementation of an Undirected Graph Component</title>

      <description> This research project entails designing, specifying, coding, testing, debugging, and documenting different implementations of an undirected graph component for the RESOLVE/C++ Component Catalog. 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. The final version employs a novel data structure
that allows each operation to execute in constant time, which dominates the other strategies.</description>

      <description> The self-certifying read-only file system enables secure distribution
of public, read-only content. It is similar to anonymous FTP or the
Web, except that it serves integrity-protected content. That is, an
adversary cannot trick a user into accepting unauthentic content. The
read-only file system pushes the cost of cryptography entirely onto
clients, allowing servers to scale to many clients. To publish
content, an administrator creates off-line a signed database of a
local file system. Untrusted replicas then serve the content to
clients. We demonstrate how to use the read-only file system to
implement certificate authorities and securely distribute software.</description>

      <description> A general purpose client/server architecture has been developed to effect the modernization of legacy code. This technique utilizes platform independent graphical user interfaces and interactive visualizations. The client/server configuration exploits a content-taggable data stream which allows seamless integration with the legacy application. This allows the client to orchestrate the collection of data in a more graphically interactive manner than was present in the original legacy interface. Application of this architecture to a NASA Global Scientific Model was demonstrated. The enhanced model incorporating this architecture will support data interpretation for NASAs TIMED satellite mission, including distributed investigations managed via a remote server.</description>

      <description> Computer networks and distribute systems are characterized by highly dynamic, concurrent, and complex processes. Thus, training in this area requires great effort from both teachers and learners.
Teachers are disatisfied with available methods for presentation, explanation, and exercises, and they
are looking for better methods to support learners.
We have developed and architecture called Highly interactive simulation of algorithms and Protocols (HiSAP), consisting of a framework to build simulations and generate applets from formally specified algorithms or protocols. 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.
We present the results of some experiments with HiSAP at three different lectures for graduate students of distributed systems and computer networks.</description>

Poster Title: Empirical Study of Course Scheduling Methods
Category: Undergraduate
Extended Abstract:
Problem and Motivation
Course scheduling involves building a timetable for courses such that
the students who want to take courses can successfully take every
course they would like. 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.

      <description> &lt;p&gt;In the last few years the (semi-) automatic sequencing of course material has become an important research issue, particularly the standardization of metadata for educational resources. 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.&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;</description>

      <description> &lt;P&gt;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.&lt;p&gt;</description>

      <description> &lt;P&gt;This article describe the use of dedicated ontology for teaching in the context of the &lt;I&gt;L&lt;/I&gt;&lt;SUP&gt;3&lt;/SUP&gt; project, a national joint project for deploying further vocational education in Germany. The requirements for the open &lt;I&gt;L&lt;/I&gt;&lt;SUP&gt;3&lt;/SUP&gt; learning infrastructure are presented in order to motivate our approach to metamodeling learning resources and services by using dedicated ontolgies of pedagogics and didactics. The basic concepts and parts of the pedagogical ontology are outlined, and the practical implications for several of today's problems such as authoring and design, retrieval and adaptive of training resources are illustrated. An overview of the &lt;I&gt;L&lt;/I&gt;&lt;SUP&gt;3&lt;/SUP&gt; runtime architecture shows how the didactical ontology is used to deliver adaptive learning.&lt;/P&gt;</description>

      <description> &lt;P&gt;We used our Original Interactive Remote Instruction (IRI) system to teach scores of university classes over the past years at sites up to 300 km apart. While this system is a prototype, its use in real classes allows us to deal with crucial issues in distributed education instruction systems. We describe our motivation and vision for a reimplementation of IRI that supports synchronous and asynchronous distance education. This new version, called IRI-h (h for hetergeneous), is coded in Java and executes on several different platforms. IRI-h extends IRI both to multiple platforms and heterogeneous network experiences with the developing prototype, including preliminary performance evaluation, and also unresolved issues still to be addressed.&lt;/P&gt;</description>

      <description> &lt;P&gt;Many educational resources and objects have been developed as Java applets or applications, which can accessed by simply downloading them from various repositories. It is often necessary to share these resources in real time, for instance when an instructor teaches remote students how to use a certain resource explains the theory behind it. We have developed some tools for this purpose that emulate a virtual classroom, and are primarily designed for synchronous sharing of resources. They enable participants to share Java objects in real time and also allow the instructor to dynamically manage the telebearing session.&lt;/P&gt;</description>
