Product-based learning in software engineering education

Product-based learning in software engineering education

39th Annual Frontiers in Education Conference: Imagining and Engineering Future CSET Education, FIE 2009

作者： Ragan, Eric D. Frezza, Stephen Cannell, Jeremy Center for Human-Computer Interaction Department of Computer Science Virginia Tech United States Computer and Information Science Department Gannon University United States Computer and Information Science Department United Kingdom

Problem-based learning is a pedagogy that employs open-ended problems as a means of increasing student motivation and interaction in addition to achieving the intended educational goals. We present product-based learning as an extension of collaborative problem-based learning by focusing on the design and development of a product as a solution to a proposed problem. In this approach, the instructor becomes an active member of the project team, working with the students to achieve the product vision. Through this method, students take control of their own learning while working together towards group success. Such a course design allows students to become active learners in achieving learning objectives, while at the same time providing project management and team-working experience. We explain the concept of product-based learning and demonstrate the process through the design and development of an educational software application. This project shows that the product-based method can promote positive attitudes, social interaction, and intentional learning in students while motivating them to achieve the intended learning objectives. ©2009 IEEE.

2nd International Conferences on Advances in computer-human interactions, ACHI 2009

作者： Humphries, Will McCrickard, D. Scott Neale, Dennis Center for HCI Department of Computer Science Virginia Tech. Blacksburg VA United States Center for HCI Industrial and Systems Engineering Dept. Virginia Tech. Blacksburg VA United States

Designing CSCW systems that support the widely varying needs of targeted users is difficult. There is no silver bullet technology that enables users to effectively collaborate with one another in different contexts. We propose a method of collaborative systems evaluation that enables novice evaluators to make insightful observations about the systems they evaluate at a level comparable to experts in certain situations. These observations come in the form of a categorical breakdown analysis of a laboratory study. The quantity and type of breakdowns can then be connected to recommended CSCW tools and features developed and described in the related literature. We conducted a study to explore the results generated when the method was applied by both experts and novices in the field of CSCW. We observed that experts found the method to be usable, and that novices capitalized on the knowledge embodied in the breakdown categories to make categorizations similar to those of experts. © 2009 IEEE.

IEEE Symposium on 3D User Interfaces (3DUI)

作者： Tao Ni Ryan P. McMahan Doug A. Bowman Virginia Polytechnic Institute and State University Blacksburg VA US Department of Computer Science and Center for Human Computer Interaction Virginia Technology USA Dept. of Computer Science and Center for Human Computer Interaction Virginia Tech

Traditional menu designs are not well-suited for command selection on distant displays. We describe a *** interaction technique called the "roll-and-pinch menu" (rapMenu), and investigate the design space of remote menu selection using freehand gestural input. The rapMenu maps intuitive hand postures and gestures to a radial menu layout at two levels of granularity: the user rolls her hand to alter the wrist orientation, which makes a group of menu items selectable; then she touches her thumb to a particular finger (forming & pinch gesture) to select a specific item in that group. We present the visual design and behavior of the rapMenu, consider related design issues, examine design variations, and discuss the strengths and limitations of our approach.

11th IFIP TC 13 International Conference on human-computer interaction, INTERACT 2007

作者： Tungare, Manas Dept. of Computer Science Center for Human Computer Interaction Virginia Tech. Blacksburg VA United States

Information is being disseminated much faster than we can assimilate it, leading to information overload. In addition to desktop computers, users use a vast array of other devices to manage their information, which leads to information fragmentation. It has not yet been studied how users adapt their information management practices in response to the introduction of new devices into their personal information ecosystem. As part of my doctoral research, I plan to study this evolution, which is important for the design of next-generation devices and to establish future research directions in personal information management. © IFIP International Federation for Information Processing 2007.

Conference on computer Supported Collaborative Learning: Of Mice, Minds, and Society, CSCL 2007

作者： Kim, Kibum Tatar, Deborah Harrison, Steve Center for Human Computer Interaction Department of Computer Science Virginia Tech. United States

Peripheral participation is fundamental to collaborative learning. In the classroom, we see two situations in which peripheral participation is essential: formative assessment, during which a teacher attempts to assess the utility of an ongoing activity and intervenes if necessary;and peer-monitoring, during which a student attempts to learn what other students are doing. When augmenting the classroom with handheld, wireless computing devices, handling peripheral participation becomes more difficult. The proposed new handheld network service, Look, allows a late overhearer, who has not witnessed the creation of common ground, to monitor the interaction between group members already engaged in a collaborative situated learning without interrupting. Laboratory experiences with our prototypes indicate that Look balances lightweight implementation, ease of use, and utility in a way that could enhance classroom communication and learning.

A challenge in presenting augmenting information in outdoor augmented reality (AR) settings lies in the broad range of uncontrollable environmental conditions that may be present, specifically large-scale fluctuations in natural lighting and wide variations in likely backgrounds or objects in the scene. In this paper, we present a active AR testbed that samples the user's field of view, and collects outdoor illuminance values at the participant's position. The main contribution presented herein is a user-based study (conducted using the testbed) that examined the effects on user performance of four outdoor background textures, four text colors, three text drawing styles, and two text drawing style algorithms for a text identification task using an optical, see-through AR system. We report significant effects for all these variables, and discuss design guidelines and ideas for future work. © 2007 IEEE.

International Symposium on Collaborative technologies and Systems

Sufficient tools for students with learning disabilities and attention deficit disorder have not yet been established. We believe that the current tools these students can use call for a drastic change in traditional learning paradigms by either the instructor or the pupil. To fill this gap, we propose our tool, taking notes together (TNT), as a collaborative note taking tool that will help in equalizing the classroom for students with disabilities. This tool allows students to collaboratively tag classroom lecture/discussion in real time through synchronized transcription and audio recording. TNT provides a visualization that highlights the important classroom points and we argue facilitates better recall and a deeper understanding of the classroom material. Through our evaluation we were able to prove that all students can benefit from this tool. We also present a case study of one student with ADD and how they benefited. The tool makes the learning experience, particularly for students with special needs like LD and ADD, less stressful while still being active in the note-taking.

IEEE Symposium on 3D User Interfaces (3DUI)

作者： Ryan P. Mcmahan Doug A. Bowman Department of Computer Science Center for Human-Computer Interaction Virginia Tech Antenna Group USA

System control - the issuing of commands - is a critical, but largely unexplored task in 3D user interfaces (3DUIs) for immersive virtual environments (IVEs). The task sequence (the order of operations in a system control task) is an important aspect of the design of a system control interface (SCI), because it affects the way the user must think about accomplishing the task. Most command line interfaces are based on the action-object task sequence (e.g. "rm ***"). Most graphical user interfaces (GUIs) are based on the object-action task sequence (e.g. click on an icon then select "delete" from a pop-up menu). An SCI for an IVE should be transparent and induce minimal cognitive load, but it is not clear which task sequences support this goal. We designed an experiment using an interior design application context to determine the cognitive loads induced by various task sequences in IVEs. By subtracting the expected time for a user to complete the task from the total time, we have estimated the cognitive time, dependent only on task sequence. Our experiment showed that task sequence has a significant effect on the cognitive loads induced in IVEs. The object-action sequence and similar task sequences induce smaller cognitive loads than those induced by the action-object sequence. These results can be used to create guidelines for creating 3DUIs for IVEs
