Scientists study connection between Great Plains precipitation and agricultural irrigation

News From NSF - Wed, 07/11/2018 - 06:00

Can crop irrigation affect the clouds that form high above farm fields? Indeed it can, say atmospheric scientists.

Agricultural irrigation to meet a growing demand for food is adding significant amounts of water to the land surface and altering regional land use and land cover. These changes affect lower atmosphere circulation, potentially influencing cloud development and precipitation.

To further understand how irrigation may be affecting precipitation, scientists from ...

Capstones and Large Projects in Computing Education

ACM TOCE and InRoads - Tue, 07/10/2018 - 20:00
Mark Sherriff, Sarah Heckman

Capstone and large projects in computing education are used as a vehicle for giving students as close to a “real-world” experience in software development as possible within the constraints of a computing degree program. This special issue presents four articles that focus on empirical research on capstone or other large-scale projects. These articles discuss areas such as project selection, working with external stakeholders, choosing the appropriate development methodology, incorporating creative activities to support student engagement, and learning.

A Multi-Institutional Perspective on H/FOSS Projects in the Computing Curriculum

Many computer science programs have capstone experiences or project courses that allow students to integrate knowledge from the full breadth of their major. Such capstone projects may be student-designed, instructor-designed, designed in conjunction with outside companies, or integrated with ongoing free and open source (FOSS) projects. The literature shows that the FOSS approach has attracted a great deal of interest, in particular when implemented with projects that have humanitarian goals (HFOSS). In this article, we describe five unique models from five distinct types of institutions for incorporating sustained FOSS or HFOSS (alternatively H/FOSS) project work into capstone experiences or courses. The goal is to provide instructors wishing to integrate open source experiences into their curriculum with additional perspectives and resources to help in adapting this approach to the specific needs and goals of their institution and students.

Involving External Stakeholders in Project Courses

ACM TOCE and InRoads - Tue, 07/10/2018 - 20:00
Jan-Philipp Steghöfer, Håkan Burden, Regina Hebig, Gul Calikli, Robert Feldt, Imed Hammouda, Jennifer Horkoff, Eric Knauss, Grischa Liebel

Problem: The involvement of external stakeholders in capstone projects and project courses is desirable due to its potential positive effects on the students. Capstone projects particularly profit from the inclusion of an industrial partner to make the project relevant and help students acquire professional skills. In addition, an increasing push towards education that is aligned with industry and incorporates industrial partners can be observed. However, the involvement of external stakeholders in teaching moments can create friction and could, in the worst case, lead to frustration of all involved parties. Contribution: We developed a model that allows analysing the involvement of external stakeholders in university courses both in a retrospective fashion, to gain insights from past course instances, and in a constructive fashion, to plan the involvement of external stakeholders.

A Scalable Methodology to Guide Student Teams Executing Computing Projects

ACM TOCE and InRoads - Tue, 07/10/2018 - 20:00
Jeffrey S. Saltz, Robert R. Heckman

This article reports on a sequential mixed-methods research study, which compared different approaches on how to guide students through a semester-long data science project. Four different methodologies, ranging from a traditional “just assign some intermediate milestones” to other more Agile methodologies, were first compared via a controlled experiment. The results of this initial experiment showed that the project methodology used made a significant difference in student outcomes. Surprisingly, the Agile Kanban approach was found to be much more effective than the Agile Scrum methodology. Based on these initial results, in the second semester, we focused on use of the Kanban methodology.

Software Theater—Teaching Demo-Oriented Prototyping

ACM TOCE and InRoads - Tue, 07/10/2018 - 20:00
Stephan Krusche, Dora Dzvonyar, Han Xu, Bernd Bruegge

Modern capstone courses use agile methods to deliver and demonstrate software early in the project. However, a simple demonstration of functional and static aspects does not provide real-world software usage context, although this is integral to understand software requirements. Software engineering involves capabilities such as creativity, imagination, and interaction, which are typically not emphasized in software engineering courses. A more engaging, dynamic way of presenting software prototypes is needed to demonstrate the context in which the software is used. We combine agile methods, scenario-based design, and theatrical aspects into software theater, an approach to present visionary scenarios using techniques borrowed from theater and film, including props and humor.
