Project-Based Learning (PBL) is a teaching method used in many Computer Science courses. To implement it, it is necessary to choose good problems that will drive students’ learning. These problems have to instigate students interest, encourage collaboration and help them to develop their knowledge of course-related topics. This paper presents a case study that sought to verify how the Lean Startup Idea Invalidation process applied with a Validation Board a business strategy assessment tool may assist in the choice of significant problems. Initial results indicate that this method helps students discard bad ideas, improve on the most interesting ones and choose products that are actually used by real users.

Collaborative work involving teams and individuals distributed across the globe is an inevitable trend. Because of that, the expertise is getting increasingly distributed and we have seen a growing need for technologies to support remote collaboration. Despite this need, the differences of technologies used to support remote collaboration are unknown, especially considering different kinds of physical tasks, such as analytical tasks and construction tasks. In order to better understand their impact on collaborative behaviors, perceptions, and performance, we conducted a lab setting study to evaluate two different arrangements of technology: a handheld model and a hands-free model. These models were compared for both, analytical and construction tasks. Our results suggest us that hands-free setting is more suitable for analytical tasks, while the handheld setting is more suitable for construction tasks. These differences among technological setups for remote collaboration on physical tasks motivate additional studies, especially long-term studies in natural settings, which could investigate aspects of collaboration that may not have been explored on our lab setting study.

Resumo: Design Science é o paradigma para método de pesquisa que suporta a criação de artefatos inovadores para resolver problemas complexos da vida real. Antes de definir como este metodo deve ser utilizado especi camente na area de Sistemas de Informação (S.I.), e importante ressaltar suas características genericas e como ele se diferencia do design rotineiro ou pro ssional.
