Do students learn to model OR/MS problems better by using computer-based interactive tutorials and, if so, does increased interactivity in the tutorials lead to better learning? In order to determine the effect of different levels of interactivity on student learning, we used screen capture technology to design interactive support materials for modeling and solving the transportation problem in a spreadsheet. A controlled experiment was carried out and the results indicate a general support for the effectiveness of interactive tutorials in enhancing students' learning of modeling concepts. However, the study also found that excessive interactivity increased the cognitive load for the students and hindered their learning by making it difficult for them to consolidate concepts, integrate previous knowledge, and create meaningful mental models of the process.

Every year the University of South Australia is supporting and sponsoring projects which are innovative in the way teaching and learning is conducted. In this paper we would like to discuss one of our projects, called interactive Electronic tutorials (IET). tutorials play a vital role in engineering education, where the theory from lectures is put into practice through problem solving and going through examples. The original idea in 1999 was to create IET for students that would make them take an active part in their education and practice and allow them to learn independently. Consequently the IET were modified and reconstructed according to feedback received from students. The final modification was done in 2004, when the Internet version of EIT was introduced, enabling students to conduct tutorials without time restrictions and without a location restriction unlike before. We would like to share our experiences with web based teaching and learning, where the classical components of lectures, tutorials and practicals are still partially present but combined with the Internet components. We have specifically concentrated on the developments and improvements of IET based on our students' feedback and our observations during a six years period.

The presentation describes the set of ready to use simulation software that can be utilized for both the lesson illustrations and the virtual lab assignments. The interactive simulations allow learners to explore a topic by comparing and contrasting different scenarios. Users may get a deeper exposure to the subject matter either by modifying parts of existing simulation or by building a new simulation from scratch. Another advantage for the users is the ability of simulation illustration to be paused and restarted for reflection and note taking. Each chapter of the course is followed by originally developed computerized test. The computerized tests are three levels hierarchical applications that allow the random access to the question data bank.

As the students of the 21(st) century begin to enter into higher education, faculty's pedagogical styles and delivery methods must evolve to address the ever changing needs and skills of the student and society. One such method is through the use of web-based course management delivery systems and interactive software. Web-based interactive course management tools are relatively new educational phenomena. In the therapeutic and rehabilitative exercise curriculums this powerful new instrument could be utilized to enhance cognitive comprehension of basic theories, definitions and applications as well as function as a virtual assistant for the learning and mastery of various psychomotor skills utilized in manual therapy as well as a host of other skills necessary to succeed within the profession. Utilization of such tools allows for necessary foundational cognitive building outside the traditional classroom creating a more inclusive environment inside the classroom for deeper and richer problem-based learning exercise. In the rehabilitation settings it is not only important that the student understand the material but that they develop the necessary critical thinking skills for appropriate application of theoretical knowledge. It has been shown that problem-based learning is an effective way to improve an individual's critical thinking skills. In our model careful planning and implementation was needed to develop an interactive web-based instrument that would serve all students in the class regardless of their learning style or rate of comprehension.

The purpose of this paper is to provide a multifacetted approach to interactive analysis and modeling of time series, signals, and dynamical data sets. The models use statistical regression analysis and are built in an incremental way from a set of simple functional units. The analysis is supported by data visualization and on-line adaptive tutorials accessed on the World Wide Web. This work extends our results obtained for the Landsat-5 and Landsat-7 calibration data. The another objective is to educate the user about available mathematical models and also to allow the user to build those models interactively through applets prepared by the authors on a Web server. These models may be constructed for the user's own data set. The approach is illustrated using the calibration data sets for the Landsat sensors, we also discuss agent communication framework of regression models and calibration data. However, the same integrated approach can be used for other data domains. This type of approach is consistent with other recent activities regarding semantic web.

This study examined the effectiveness of a series of Web-based, multimedia tutorials on methods of human body composition analysis. tutorials were developed around four body composition topics: hydrodensitometry (underwater weighing), dual-energy X-ray absorptiometry, bioelectrical impedance analysis, and total body electrical conductivity. Thirty-two students enrolled in the course were randomly assigned to learn the material through either the Web-based tutorials only ("Computer"), a traditional lecture format ("Lecture"), or lectures supplemented with Web-based tutorials ("Both"). All students were administered a validated pretest before randomization and an identical posttest at the completion of the course. The reliability of the test was 0.84. The mean score changes from pretest to posttest were not significantly different among the groups (65.4 +/- 17.31, 78.82 +/- 21.50, and 76 +/- 21.22 for the Computer, Both, and Lecture groups, respectively). Additionally, a Likert-type assessment found equally positive attitudes toward all three formats. The results indicate that Web-based tutorials are as effective as the traditional lecture format for teaching these topics.

B-Course is a free web-based online data analysis tool, which allows the users to analyze their data for multivariate probabilistic dependencies. These dependencies are represented as Bayesian network models. In addition to this, B-Course also offers facilities for inferring certain type of causal dependencies from the data. The software uses a novel "tutorial stylerdquo; user-friendly interface which intertwines the steps in the data analysis with support material that gives an informal introduction to the Bayesian approach adopted. Although the analysis methods, modeling assumptions and restrictions are totally transparent to the user, this transparency is not achieved at the expense of analysis power: with the restrictions stated in the support material, B-Course is a powerful analysis tool exploiting several theoretically elaborate results developed recently in the fields of Bayesian and causal modeling. B-Course can be used with most web-browsers (even Lynx), and the facilities include features such as automatic missing data handling and discretization, a flexible graphical interface for probabilistic inference on the constructed Bayesian network models (for Java enabled browsers), automatic prettyHyphen;printed layout for the networks, exportation of the models, and analysis of the importance of the derived dependencies. In this paper we discuss both the theoretical design principles underlying the B-Course tool, and the pragmatic methods adopted in the implementation of the software.
