    In the realm of computer programming, the experience of writing a program is used to reinforce concepts and evaluate ability. This research uses three case studies to evaluate the introduction of testing through Kolb\u27s Experiential Learning Model (ELM). We then analyze the impact of those testing experiences to determine methods for improving future courses. The first testing experience that students encounter are unit test reports in their early courses. This course demonstrates that automating and improving feedback can provide more ELM iterations. The JUnit Generation (JUG) tool also provided a positive experience for the instructor by reducing the overall workload. Later, undergraduate and graduate students have the opportunity to work together in a multi-role Human-Computer Interaction (HCI) course. The interactions use usability analysis techniques with graduate students as usability experts and undergraduate students as design engineers. Students get experience testing the user experience of their product prototypes using methods varying from heuristic analysis to user testing. From this course, we learned the importance of the instructors role in the ELM. As more roles were added to the HCI course, a desire arose to provide more complete, quality assured software. This inspired the addition of unit testing experiences to the course. However, we learned that significant preparations must be made to apply the ELM when students are resistant. The research presented through these courses was driven by the recognition of a need for testing in a Computer Science curriculum. Our understanding of the ELM suggests the need for student experience when being introduced to testing concepts. We learned that experiential learning, when appropriately implemented, can provide benefits to the Computer Science classroom. When examined together, these course-based research projects provided insight into building strong testing practices into a curriculum

    Robotic systems under development in the Santa Clara University Robotic Systems Laboratory (RSL) generate large amounts of data that must be interpreted in real-time. Many dimensions of this data must be visualized at once, such as temperature, location, and certainty of the measurement. Current data visualization softwares (such as Mathematica and Simulink) are ill-suited to visualize this much data, due to lack of customization. To solve this, we propose a system that allows users to view real-time streaming data in a virtual reality environment. This allows the user to easily interpret large, detailed datasets through an intuitive interface

    The ROLE project (Responsive Open Learning Environments, EU 7th Framework Programme, grant agreement no.: 231396, 2009-2013) was focused on the next generation of Personal Learning Environments (PLEs). A ROLE PLE is a bundle of interoperating widgets - often realised as cloud services - used for teaching and learning. In this paper, we first describe the creation of new ROLE widgets and widget bundles at Galileo University, Guatemala, within a cloud-based infrastructure. We introduce an initial architecture for cloud interoperability services including the means for collecting interaction data as needed for learning analytics. Furthermore, we describe the newly implemented widgets, namely a social networking tool, a mind-mapping tool and an online document editor, as well as the modification of existing widgets. The newly created and modified widgets have been combined in two different bundles that have been evaluated in two web-based courses at Galileo University, with participants from three different Latin-American countries. We measured emotional aspects, motivation, usability and attitudes towards the environment. The results demonstrated the readiness of cloud-based education solutions, and how ROLE can bring together such an environment from a PLE perspective

    Abstract. Usability is described as follows “The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use”. Usability plays a crucial role in the success of interactive products and services. With good usability can be achieved an important competitive advantage in an ever-growing market if it is involved in software products development life cycle. User experience (UX) is based on people’s expectations and the following emotions and it involves extensively everything that happens outside the screen. UX design aims to emphasize features that are bringing pleasure in addition to practicality. Usability evaluation is easy and very cost-effective way to analyze user interface and find possible usability problems. In general, the empirical methods like heuristic evaluation and usability testing are the most used and principal means to evaluate user interfaces. This thesis focuses on exploring the usability of Kodinportti Mobile application. The motivation for the study is to improve its user interface (UI) more user-friendly using usability research methods that include heuristic evaluation, usability testing, and user experience research. The practical work in the study is responsible by the University of Oulu usability testing course student group and the group also reports the results of research. The goal of the study is to redesign the app’s UI. Kodinportti Mobile is designed to meet the needs of the residents of the housing association and serves as a supplement to the electronic bulletin board for the residents. Mobile application UI design applies the same basic guidelines as any other UI design process and in mobile application UI design, it is often recommended to keep it simple as possible and cut out as much as possible. The results of usability research revealed several flaws in the apps usability and user experience. In the final phase of the thesis, the concept plan of new UI was designed based on the research results. There was also a perception during the process that it would be recommendable that designers are involved in all stages of the process. That would improve the process and minimize the possibility of misunderstandings during the process, which will certainly have a positive impact on the result
