System Projector: An Automatic Program Rewriting Tool For Non-Ground Answer Set Programs, Yuliya Lierler Aug 2019

System Projector: An Automatic Program Rewriting Tool For Non-Ground Answer Set Programs, Yuliya Lierler

Yuliya Lierler

Answer set programming is a popular constraint programming paradigm that has seen wide use across various industry applications. However, logic programs under answer set semantics often require careful design and nontrivial expertise from a programmer to obtain satisfactory solving times. In order to reduce this burden on a software engineer we propose an automated rewriting technique for non-ground logic programs that we implement in a system PROJECTOR. We conduct rigorous experimental analysis, which shows that applying system PROJECTOR to a logic program can improve its performance, even after significant human-performed optimizations. This talk will present PROJECTOR and considered experimental analysis …

Simulations In Prisons, Kim Read Jun 2015

Simulations In Prisons, Kim Read

Kim Read

As society has moved online, prison education has significantly lagged behind, hampering efforts to prepare released prisoners for work, education, and life outside a prison cell. Prisons have lacked the technology and educational programming to ready inmates for reintroduction into a digital society. This paper explores the benefits and challenges of eLearning in prisons and the role simulations could play in reducing recidivism and preparing released inmates for a technology-driven world.

A Computer Science Linked-Courses Learning Community, Amber Settle, John Lalor, Theresa Steinbach Jun 2015

A Computer Science Linked-Courses Learning Community, Amber Settle, John Lalor, Theresa Steinbach

Amber Settle

Previous work has shown that factors such as student engagement and involvement can impact progress for computer science majors. One promising approach for improving student engagement is learning communities, which have a long history in academia but are relatively uncommon in computing. In this article we describe a linked-courses learning community for women and men of color majoring in development-focused computing degrees. We provide logistical information about the first offering of the learning community and assess the effectiveness of the community via a student survey. Our results show that students in the learning community are more likely to report that …

Reconsidering The Impact Of Cs1 On Novice Attitudes, Amber Settle, John Lalor, Theresa Steinbach Feb 2015

Reconsidering The Impact Of Cs1 On Novice Attitudes, Amber Settle, John Lalor, Theresa Steinbach

Amber Settle

Student success in an introductory programing course is crucial, both because it influences retention and because student attitudes and habits in a first course can have a lasting impact on student success in computer science as a field. In this paper we present results about student attitudes and habits before and after a CS1 class. Statistically significant attitude differences were found in three areas: students were less likely to report they were good at programming, more likely to agree they are challenged by programming problems they can't understand immediately, and are less likely to report that computer science allows them …

The Critical Role Of Cubesat Spacecraft In A Multi-Tier Mission For Mars Exploration, Jeremy Straub Nov 2014

The Critical Role Of Cubesat Spacecraft In A Multi-Tier Mission For Mars Exploration, Jeremy Straub

Jeremy Straub

A multi-tier architecture is under development (with similar craft heterogeneity to Fink's work on ‘tier scalable’ missions) which will facilitate autonomous local control of multiple heterogeneous craft. This mission architecture has been developed with a Mars mission in mind and has included CubeSats in a variety of critical mission roles.

Two concepts will be presented: the addition of CubeSats to a larger-scale multi-tier mission, where the CubeSats serve a supporting role and a mission driven by CubeSat orbital capabilities. In the first, CubeSats are utilized to augment the area of spatial coverage that can be obtained and the temporal coverage …

Three Views On Motivation And Programming, Amber Settle, Arto Vihavainen, Juha Sorva Jun 2014

Three Views On Motivation And Programming, Amber Settle, Arto Vihavainen, Juha Sorva

Amber Settle

Teaching programming is one of the most widely studied areas in computing education. Part of the reason for this may be the difficulty students experience when learning programming which makes it a challenging endeavor for instructors. There is a relationship between student motivation and success in learning to program [1], and motivation is also important in the bigger picture for computing educators, having inspired two ITiCSE working groups [2]. What is perhaps surprising is that motivation does not play an equal role in the various subfields of programming education. 

In this panel we discuss three areas of programming education, emphasizing …

Web-Based Student Peer Review: A Research Summary, Edward F. Gehringer Mar 2014

Web-Based Student Peer Review: A Research Summary, Edward F. Gehringer

Edward F Gehringer

Interest in Web-based peer-review systems dates back nearly 20 years. Systems were built to let students give feedback to other students, mainly to help them improve their writing. But students are not necessarily effective peer reviewers. Left to their own devices, they will submit cursory reviews, which are not very helpful to their peers. Techniques have been developed to improve the quality of reviews. Calibration is one such technique. Students are asked to assess samples of writing that have previously been assessed by experts. Students must submit an evaluation “close enough” to the experts’ before they are allowed to review …

Beyond Computer Science: Computational Thinking Across Disciplines, Amber Settle, Debra S. Goldberg, Valerie Barr Jun 2013

Beyond Computer Science: Computational Thinking Across Disciplines, Amber Settle, Debra S. Goldberg, Valerie Barr

Amber Settle

In her influential CACM article, Jeannette Wing argues that computational thinking is an emerging basic skill that should become an integral part of every child’s education [14]. The potential impact of any approach for incorporating computational thinking into the curriculum is limited by the low enrollment in computing classes and the homogeneous population choosing these classes. While there are continuing efforts to draw students into computing courses, a complementary approach is to bring computational thinking into courses already taken by a diverse set of students. Because computing is transforming society and impacting many areas of study, providing students with meaningful …

Turning The Tables: Learning From Students About Teaching Cs1, Amber Settle Oct 2012

Turning The Tables: Learning From Students About Teaching Cs1, Amber Settle

Amber Settle

Programming has a central role in the computing curriculum, and introductory programming classes have been extensively studied in the computer science education literature. However, most of the studies focus on the effectiveness of various pedagogical approaches on student learning and engagement, and relative little attention is paid to faculty development. The gap in the literature puts CS1 faculty interested in effectively implementing innovative pedagogical approaches in a difficult situation. This article argues that taking a behaviorist approach to the CS1 classroom can provide much-needed feedback. Students provide instructors with one of the best sources of information about effective programming instruction, …

Interactive Learning Online: Challenges And Opportunities, Mihaela Sabin, Amber Settle, Becky Rutherfoord

Amber Settle

Since the early 1990s online education and online learning systems have held the promise of increasing instructional productivity and reducing costs without sacrificing educational quality. There is no evidence to date that such promise has materialized. The impetus of the newest developments with free online courses to hundreds of thousands of students might drastically transform how we teach more and better with less. The innovation that prompted this panel is called Interactive Learning Online (ILO), and has the distinctive feature of highly interactive, machine-guided instruction that can be scaled to accommodate a large number of students who benefit from targeted …

Imagining Emergent Metadata, Realizing The Emergent Web, Jason A. Bengtson Mar 2012

Imagining Emergent Metadata, Realizing The Emergent Web, Jason A. Bengtson

Jason A Bengtson

Current metadata schemas are largely analog technology grafted onto the digital format. They have three inherent limitations that need to be transcended: they generate a static product which must be changed manually, they revolve around the needs of human, rather than mechanistic agents, and they are limited by the imagination and organizational capabilities of human agency. The author argues that to meet future challenges metadata will have to take a more flexible, adaptive form that centers on the needs of the machine in searching, interpretation and organization until the information it proxies enters into the human sphere. The author further …

The Art Of Redirection: Putting Mobile Devices Where You Want Them, Jason A. Bengtson

Jason A Bengtson

Mobile technology has exploded, with many libraries experiencing a surge in access to their resources through mobile devices. In response, many institutions have created or are creating mobile sites designed to accommodate themselves to the unique strictures of these devices. One hurdle faced by these organizations, however, is getting mobile users to those sites. One solution is mobile redirect scripts, which automatically redirect mobile users from a regular page to a mobile page. These scripts come in various forms and present unique challenges to libraries. How are these scripts created? What triggers can or should be used to activate them? …

Engaging Game Design Students Using Peer Evaluation, Amber Settle, Charles Wilcox, Chad Settle Oct 2011

Engaging Game Design Students Using Peer Evaluation, Amber Settle, Charles Wilcox, Chad Settle

Amber Settle

Many information technology educators have worked in recent years to develop courses to attract students to the field. As faculty achieve success with technical courses designed to be appeal to a broad audience, it can be hard to maintain the initial excitement particularly as multiple sections of the courses are taught on a continuing basis. In this article we describe a project that added peer evaluation to an assessment in a game design course with a large non-major audience. While controversial, peer evaluation has shown some promise in motivating students to work harder and in improving certain key skills. Consistent …

Computational Thinking In A Game Design Course, Amber Settle Oct 2011

Computational Thinking In A Game Design Course, Amber Settle

Amber Settle

As a part of an NSF-funded project to enhance computational thinking in undergraduate general education courses, activities and assessments were developed for a game design course taught at DePaul University. The focus of the course is on game analysis and design, but the course textbook uses an approach that is heavily grounded in computational thinking principles. We describe the course activities and assignments and discuss an initial assessment of those materials. Our results show that there is a gap in difficulty between several of the activities and indicate that the materials developed help students to better learn the computational thinking …

Computational Thinking (Ct): On Weaving It In, Paul Curzon, Joan Peckham, Harriet G. Taylor, Amber Settle, Eric Roberts

Amber Settle

Computing offers essential problem-solving tools needed for contemporary challenges. The role of computing in education, and appropriate pathways for modern students, are of concern [10]. Educators recognize the importance of improving information technology (IT) skills and fluency, and studies have developed guidelines [7][8], but the analytical concepts and tools of computing have benefits beyond IT fluency. CT [12] continues earlier discussions on the nature of computing, [3][9]. This has helped the computing community to strengthen definition of the problem solving skills that computing brings to society, through education, outreach, and research. Recently, CT has served as a basis for several …
