In this paper we analyze the teaching and learning of parallel processing through performance analysis using a software tool called Prober. This tool is a functional and performance analyzer of parallel programs that we proposed and developed during an undergraduate research project. Our teaching and learning approach consists of a practical class where students receive explanations about some concepts of parallel processing and the use of the tool. They do some oriented and simple performance tests on parallel programs and analyze their results using Prober as a single aid tool. Finally, students answer a self-assessment questionnaire about their formation, their knowledge of parallel processing concepts and also about the usability of Prober. Our main goal is to show that students can learn concepts of parallel processing in a clearer, faster and more efficient way using our approach.

Review of digital educational resources, such as course modules, simulations, and data analysis tools, can differ from review of scholarly articles, in the heterogeneity and complexity of the resources themselves. The Partnership Review Model, as demonstrated in two cases, appears to promote cooperative interactions between distributed resource reviewers, enabling reviewers to effectively divide up the task of reviewing complex resources with little explicit coordination. The shared structural outline of the resource made visible in the review environment enables participants to monitor other reviewers' actions and to thus target their efforts accordingly. This reviewing approach may be effective in educational digital libraries that depend on community volunteers for most of their reviewing.
A main issue in collaborative learning is providing support and monitoring both the individual learners and the group activities. In this sense, there is a variety of functions that might be accomplished by a collabor...

We present a new learning method of microprocessor architecture based on design and verification using functional simulation. Our main goals are to improve and optimize the learning process, motivating students to study and learn theoretical and practical aspects of microprocessor architecture, using functional simulators to validate the microprocessor design and to construct knowledge; and develop research activities during an undergraduate course. Our method is based on learning, constructivism theory, problem based learning, group projects, design of academic microprocessors as motivation for theory study/learning and verification of designed microprocessors through functional simulators developed by students. To validate the proposed method we analyze two microprocessors and functional simulators: a digital signal processor using ASIP and RISC concepts, and a RISC ASIP home automation processor. They were developed in a computer architecture course (computer science, PUC-Minas, Brazil) as the application of this method. In the conclusion students and professor analyze the results, highlighting the main differences, advantages and disadvantages of the new method.

Background: There is strong support for educating physicians in medical informatics, and the benefits of such education have been clearly identified. Despite this, North American medical schools do not routinely provide education in medical informatics. Methods: We conducted a qualitative study to identify issues facing the introduction of medical informatics into an undergraduate medical curriculum. Nine key informants at the University of Toronto medical school were interviewed, and their responses were transcribed and analyzed to identify consistent themes. Results: The field of medical informatics was not clearly understood by participants. There was, however, strong support for medical informatics education, and the benefits of such education were consistently identified. In the curriculum we examined, medical informatics education was delivered informally and inconsistently through mainly optional activities. Issues facing the introduction of medical informatics education included: an unclear understanding of the discipline;faculty and administrative detractors and, the dense nature of the existing undergraduate medical curriculum. Conclusions: The identified issues may present serious obstacles to the introduction of medical informatics education into an undergraduate medicine curriculum, and we present some possible strategies for addressing these issues.

This paper presents a collaborative virtual environment for problem solving in civil engineering, which represents a building with problems related to its structural design (e.g., fissures). In this environment the students play the role of civil engineers. They need to detect the structural problems and evaluate their causes in order to be able to solve them. To accomplish this, the students can act upon the structural elements included in the environment (e.g., pillars) or make use of the working tools that are available (e.g., tape measure). This distributed environment allows for the exploration of the possibility of student collaboration in virtual reality. Furthermore, its design intends to provide a way to implement problem solving in collaborative environments in which genuine interdependence occurs i.e. team members must have different knowledge or abilities in order to create genuine collaboration.

There is an increasing need to link the large amount of genotypic data, gathered using microarrays for example, with various phenotypic data from patients. The classification problem in which gene expression data serve as predictors and a class label phenotype as the binary outcome variable has been examined extensively, but there has been less emphasis in dealing with other types of phenotypic data. In particular, patient survival times with censoring are often not used directly as a response variable due to the complications that arise from censoring. We show that the issues involving censored data can be circumvented by reformulating the problem as a standard Poisson regression problem. The procedure for solving the transformed problem is a combination of two approaches: partial least squares, a regression technique that is especially effective when there is severe collinearity due to a large number of predictors, and generalized linear regression, which extends standard linear regression to deal with various types of response variables. The linear combinations of the original variables identified by the method are highly correlated with the patient survival times and at the same time account for the variability in the covariates. The algorithm is fast, as it does not involve any matrix decompositions in the iterations. We apply our method to data sets from lung carcinoma and diffuse large B-cell lymphoma studies to verify its effectiveness.
