Lecture-Free Calculus For Science And Engineering, Benjamin Wiles
Lecture-Free Calculus For Science And Engineering, Benjamin Wiles
IMPACT Symposium
Plane Analytic Geometry and Calculus I (MA 16100) is a historically difficult, required course for engineering and science majors. The traditional configuration consists of 250 students meeting in a large lecture 3 times per week and twice per week in smaller recitations of size 40. Additionally, those who repeat the course often continue to encounter difficulty. A scalable re-design has been implemented to attempt to address the needs of students that are not being met in the traditional configuration by diverting resources from lecture to problem sessions and from traditional Q&A recitations to student-driven presentation/collaboration-based recitations. The students work in …

Qualitative, Tiered, Iclicker Recitation Introductions, David Blasing, Andrew Hirsch, Rebecca Lindell
IMPACT Symposium
Interactively engaging students can significantly help them understand key concepts [Hake 1998]. Additionally, students are most likely to recall the first five minutes of a presentation [Burns 1985]. Capitalizing on both of these, we altered the beginning of PHYS 272 (ELECTRIC AND MAGNETIC INTERACTIONS) recitation to include a series of qualitative, “tiered,” iClicker questions that interactively engage students and socratically teach fundamental principals in electricity and magnetism.
The series begin with a question that most students comfortably and correctly answer. Successive questions increase in difficultly and the series stops with most students struggling to identify the correct answer. Along the …

Study Of User Search Activities With Two Discovery Tools At An Academic Library, Xi Niu, Tao Zhang, Hsin-Liang Chen
Libraries Faculty and Staff Scholarship and Research
The goal of this study was to investigate and compare user search activities of two discovery tools at an academic library. The implementation of a new discovery tool (Primo by Ex Libris) to replace an existing system (VuFind) provided a unique opportunity to collect transaction logs of both systems and examine user search behavior in an empirical test. Results from a transaction log analysis and a user study of this study have contributed to the understanding of users’ search behavior and their preferences and perceptions of the two systems. We find both commonalities and differences between VuFind and Primo for …
Peering Into The Discourse Of Industrial Design Training Through A Sustainability Lens, Norman M. Su, Haodan Tan, Eli Blevis
Peering Into The Discourse Of Industrial Design Training Through A Sustainability Lens, Norman M. Su, Haodan Tan, Eli Blevis
Design Thinking Research Symposium
Now well established in HCI, the lens of sustainability may be applied to educational practices in industrial design and interaction design. By sustainability, we mean to include notions of mitigation of the environmental effects of climate change. In this paper, we present an analysis of student projects in a junior and senior industrial design class dataset. Drawing from discourse analysis, we examine how the industrial design classroom serves as a space to socially construct the philosophies and goals inherent in “good” design. We then examine how the lens of sustainability is implicated into the industrial design “way” as espoused by …

Mispronunciation Detection For Language Learning And Speech Recognition Adaptation, Zhenhao Ge
Open Access Dissertations
The areas of "mispronunciation detection" (or "accent detection" more specifically) within the speech recognition community are receiving increased attention now. Two application areas, namely language learning and speech recognition adaptation, are largely driving this research interest and are the focal points of this work.
There are a number of Computer Aided Language Learning (CALL) systems with Computer Aided Pronunciation Training (CAPT) techniques that have been developed. In this thesis, a new HMM-based text-dependent mispronunciation system is introduced using text Adaptive Frequency Cepstral Coefficients (AFCCs). It is shown that this system outperforms the conventional HMM method based on Mel Frequency Cepstral …
Developing A Framework For Determining The Contribution Of Transportation Project To Sustainable Development, Karim Ahmed Abdel Warith
Developing A Framework For Determining The Contribution Of Transportation Project To Sustainable Development, Karim Ahmed Abdel Warith
Open Access Dissertations
In the past few years, stakeholders in the transportation industry have been concerned with sustainability. However, transportation decision makers have had difficulty incorporating sustainability into transportation infrastructure decisions. This is mainly attributed to the vagueness of the term. Incorporating sustainability into transportation decision making has been a desire put forth by engineers for that past 10 years. However, with no apparent method of defining sustainability, designers and decision makers have not been able to fulfill this desire.
This investigation attempts to define sustainability in a comprehensive and quantitative manner. The research proposes a new methodology that relies on the objective …
Agriculture In A Water Scarce World, Allison Roberts, Amjad Assi, Bassel Daher, Men Li
Agriculture In A Water Scarce World, Allison Roberts, Amjad Assi, Bassel Daher, Men Li
Student Papers in Public Policy
According to the McKinsey report (2009), the world is facing a water scarcity challenge where agriculture is its predominant consumer. It accounts for approximately 3100 billion m3, or 71 percent of global water withdrawals today, and is expected to increase to 4500 billion m3 by 2030. This increase is due to a number of factors: growing population and the ever growing necessity to cater for its food needs, economic growth, the variability of precipitation trends and increase in global temperatures. In addition to the increase in water scarcity, the agricultural sector faces an enormous challenge of producing …

Ocean Sustainability, Logan Levan, Joshua Millea, Woo Choi, Mark Powell, David Flint
Student Papers in Public Policy
Oceans cover over 70% of the Earth’s surface area. They provide more than 90% of the world’s oxygen production, account for 200 billion pounds of food each year, regulate the global climate, and are the primary mode of global shipping traffic (“www.marinebio.org”). With such social, economic, and environmental value, there is a clear need to enact sustainable policies and practices concerning marine zones.

Overview: The Role Of Information Policy In Resolving Global Challenges, Sharon A. Weiner
Purdue Policy Research Institute (PPRI) Policy Briefs
Governments in many countries recognize the importance of knowledge-based societies whose citizens are adaptable and have the means to engage in continuous learning. Information societies can address global challenges far more readily than those that do not adopt its characteristics of ICTs (information and communication technologies) and connectivity; usable content; infrastructure and deliverability; and human intellectual capability.

Role Of Natural Gas In America's Energy Future: Focus On Transportation, Dharik Mallapragada, Rakesh Agrawal
Purdue Policy Research Institute (PPRI) Policy Briefs
The energy landscape of the United States for the past century has been dominated by the use of fossil fuels namely coal, petroleum, and natural gas (NG). While coal usage was dominant during the early 1900’s, petroleum has been dominant ever since the second half of the 20th century owing to increasing use of liquid fuels, gasoline and diesel, for transportation. In contrast, NG consumption in the U.S., currently at ~25% of total primary energy use, has only been steadily increasing since the early 1990’s (BP, 2012). However, the last decade has seen rapid growth in U.S. NG consumption …
Energy Independence In The Usa, Janice Ringler
Energy Independence In The Usa, Janice Ringler
Student Papers in Public Policy
During President Barack Obama’s first term and throughout the recent presidential campaign, there was much discussion about becoming energy-independent as a nation. Indeed, one of the most pressing issues facing the country today is our energy future. This is especially a concern in areas where mainstream energy sources (coal, gas, oil) do not exist, and thus must be imported. Many believe that this is a problem that communities and states are better suited to tackle than the federal government due to the flexibility and knowledge of state policy initiatives. In this brief I will propose a variety of measures that …

Astronomy / Galactic Structure - Rensselaer Polytechnic Institute, Kathryn M. Dunn
Data Curation Profiles Directory
The researcher participates in large-scale astronomical survey projects, which are collaborative efforts of many institutions and individuals. Management of the raw and processed/calibrated data is handled by those projects, but data for specific research questions is handled by the researcher. The researcher would like to have a better way to share the data behind the figures in their published papers with other researchers. The effort involved in retrieving and documenting the data so it’s usable by others is a barrier to sharing the data. It would be easier to share data from publications if it could be deposited to a …

Many national and statewide programs throughout the K-12 science education environment teach students about science in a hands-on format, including programs such as Global Learning and Observations to Benefit the Environment (GLOBE), Project Learning Tree (PLT), Project Wild, Project Wet, and Hoosier River Watch. Partnering with one or more of these well-known programs can provide many benefits to both the scientists involved in disseminating research and the K-12 educators. Scientists potentially benefit by broader dissemination of their research by providing content enrichment for educators. Educators benefit by gaining understanding in content, becoming more confident in teaching the concept, and increasing …

A Justification For Semantic Training In Data Curation Frameworks Development, Xiaogang Ma, Benjamin D. Branch, Kristin Wegner
Libraries Faculty and Staff Presentations
In the complex data curation activities involving proper data access, data use optimization and data rescue, opportunities exist where underlying skills in semantics may play a crucial role in data curation professionals ranging from data scientists, to informaticists, to librarians. Here, We provide a conceptualization of semantics use in the education data curation framework (EDCF) (Fig. 1) [1] under development by Purdue University and endorsed by the GLOBE program [2] for further development and application. Our work shows that a comprehensive data science training includes both spatial and non-spatial data, where both categories are promoted by standard efforts of organizations …

Identifying Ditch Geometry And Top Of The Bank Location Using Airborne Lidar Point Cloud, Naime Celik
Open Access Theses
The geometry of agricultural drainage ditches is very important in crop production as it impacts drainage of cropland and affects vegetation and soil erosion along the banks of the ditches. Thus, implementation of water conservation and management practices in engineered and natural ditches necessitates determination of ditch geometry along the reach of the ditch. This study explores the use of airborne commercial Light Detection and Ranging (LiDAR) technology to identify the top of the ditch banks. The method was developed to obtain the normalized cross sectional shape of the ditch using one-dimensional spline fits to ground classified points from the …

Lower Tropospheric Temperature Variability Over The Usa: A Gis Approach, Souleymane Fall, Dev Niyogi, Gilbert L. Rochon
GIS Day
We use the high resolution North American Regional Analysis (NARR) dataset to build for the United States a Temperature Change Index (TCI) based on four contributing variables derived from the layer-averaged temperature and lapse rate of the 1000mb - 700mb layer (near-surface to 3000 meters) for the 1979-2008 period. The analysis uses Geographic Information Systems (GIS) methods to identify distinct regional patterns based on aggregate temperature trends and variability scores. The resulting index allows us to identify and compare regions that experience high (low) temperature trends and variability that are referred to as hot spots (cold spots). The upper Midwest …
