How can we learn to use properly business software, digital environments, games or intelligent tutoring systems (ITS)? Mainly, we assume that the new user will learn by doing. But what about the efficiency of such a method? Our approach proposes an answer by introducing on-line coaching. In learning process, learners may need guidance to help them in their academic achievement. In this paper, we introduce a process-based assistance method to provide this help. Our method proposes to build a model using process mining upon the observations collected during previous users' experiences with the considered application. It represents the steps chaining and their impacts on the states of the overall process and is used to recommend the most suitable step to guide the current user or learner. We implemented our coaching approach in the La Rochelle University Institute of Technology jury decision system to show its relevance. [For the complete proceedings, see ED590269.]

One of the rapidly developing tools for online learning is learning through a mobile environment. Therefore, developing and improving mobile learning environments is an active topic now. One of the ways to adapt the learning environment to the user's needs is to use his context. Context of the user consists of the current context in online learning environment and physical context. This paper concentrates on the physical context and ways to improve the user's experience in a learning environment. For this an ontology-based system is presented, and Learning Context ontology is extended for User Context ontology. Also, a use-case is provided to show situations which will be covered by such an approach. [For the complete proceedings, see ED579190.]

The proceedings of a conference are presented, at which representatives from various Washington County (Maryland) women's organizations discussed education, employment, career choice, and domestic violence in relation to the status of women. The monograph first presents four position papers dealing with these conference themes: Diane E. Weaver notes the preponderance of women in low-paying jobs and the need for non-traditional career counseling; Marie E. Nowakowski discusses the failure of education to enhance the status of women in a society which is not receptive to their participation in powerful positions; Robin L. Spaid reviews the problems faced by displaced homemakers and the low priority assigned by society to women's programs; and Vicki A. Sadehvandi discusses the plight of battered women. Next, the text of Constance Ross Beims' keynote address is presented in which she discusses the historical struggle of women to gain recognition and legal rights; the low socioeconomic status of women in Maryland despite an equal rights amendment to the state's constitution; special issues related to employment, health, and education; and the limited response of government to battered, displaced, and homeless women. Finally, the monograph reviews the issues raised in small group discussions which examined each of the conference themes. The conference program, evaluation results, and a list of participants are appended. (JP)

A student's perspective of graduate level training in evaluation is presented. The primary focus is on the training of evaluators. A secondary focus is on the training of users of evaluation. The position presented in this paper is that (1) evaluation is a higher order skill comprised of many individual skills and skill sets or processes, (2) the role of coursework is in providing conceptual schemata for organizing these skill sets and for developing individual skills and processes, and (3) the role of field-based evaluation training is primarily for testing and expanding conceptual schemata to effectively integrate the many skills and processes involved in doing evaluation.

An efficient Eulerian numerical method is considered for simulating multiphase flows governed by general equation of state (EOS). The method allows interfaces between phases to diffuse in a transitional region over a small number of computational cells. The seven-equation model of Saurel and Abgrall [Saurel, R. and Abgrall, R., A multiphase Godunov method for compressible multifluid and multiphase flows, J. Comput. Phys. 150 (1999), 425 - 467] is employed to describe the compressible multiphase flows. For one dimensional flow the model which is strictly hyperbolic consists of seven equations. These equations are the volume fraction evolution equation and the conservation equations (mass, momentum and energy) for each phase. The solution of the hyperbolic equations is obtained using HLL Riemann solver. In the present work various equations of state (EOSs) have been discussed. Error analysis, number of time steps and CPU time comparisons between EOSs have been presented. Well known test cases are examined to simulate compressible as well as incompressible multiphase flows.

Computing compressible two-phase flows that consider different materials and physical properties is conducted. A finite volume numerical method based on Godunov approach is developed and implemented to solve an Euler type mathematical model. This model consists of five partial differential equations in one space dimension and it is known as the reduced model. A fixed Eulerian mesh is considered and the hyperbolic problem is tackled using a robust and efficient HLL and HLLC Riemann solvers. The performance of the two solvers is verified against a comprehensive suite of numerical case studies in one and two dimensional space. Computing the evolution of interfaces between two immiscible fluids is considered as a major challenge for the present model and the numerical technique. The achieved numerical results display a good agreement with all reference data. [ABSTRACT FROM AUTHOR]
