Coridan, Robert Henry – ProQuest LLC, 2009
This thesis outlines how meV-resolution inelastic x-ray scattering and causality-enforcing mathematics can be used to measure the dynamical density-density linear response function for liquid water with Angstrom spatial resolution and 50fs temporal resolution. The results are compared to high-resolution spectroscopic and scattering experiments and…

Hejazi, Mohamad Issa – ProQuest LLC, 2009
Closing the gap between theoretical reservoir operation and the real-world implementation remains a challenge in contemporary reservoir operations. Past research has focused on optimization algorithms and establishing optimal policies for reservoir operations. In this research, we attempt to understand operators' release decisions by investigating…

Charles, John; Mosley, Shelley; Van Winkle, Sandra – Library Journal, 2008
Gardening in the American Southwest (SW) is an extreme sport. Not only are gardeners challenged by geographic extremes from tropical deserts to subalpine locales, they must also deal with a wide range of climates. Winter in the mountains and higher regions means heavy snows, frozen soils, and temperatures that can dip below zero. In contrast,…

Kammler, David C.; Truong, Triet M.; VanNess, Garrett; McGowin, Audrey E. – Journal of Chemical Education, 2012
A collaborative environmental service-learning project was implemented between upper-level undergraduate science majors and graduate chemistry students at a large state school and first-year students at a small private liberal arts college. Students analyzed the water quality in a nature preserve by determining the quantities of 12 trace metals,…

Nam, Younkyeong – Cultural Studies of Science Education, 2012
This review explores Ben-Zvi Assaraf, Eshach, Orion, and Alamour's paper titled "Cultural Differences and Students' Spontaneous Models of the Water Cycle: A Case Study of Jewish and Bedouin Children in Israel" by examining how the authors use the concept of spontaneous mental models to explain cultural knowledge source of Bedouin…

Fung, Leo Sun-wai; Chan, Yu-nang – Asia-Pacific Forum on Science Learning and Teaching, 2009
The aim of this research is to study the effectiveness of using videoconferencing as a tool for collaborative learning on water pollution among students from two secondary schools located in different districts. The poor water quality of the nullahs in urban areas aroused the interest of students from two secondary schools in Tin Shui Wai and Wong…

Cotton, Lizzie – Early Years: An International Journal of Research and Development, 2013
This article describes how early years practitioners working in different settings, with different experiences and qualifications, can work and learn together. It is a small-scale case study of an eight-month project, with a grass-roots approach, involving early years settings within the reach area of an inner-London Children's Centre. The data…

Lee, Yeung Chung; Kwok, Ping Wai – Physics Education, 2010
Traditional methods used to teach the concept of density that employ solid objects of different masses and volumes can be supplemented by enquiry activities in which students vary the mass-to-volume ratio of the same object to test ideas about density and flotation. A simple substance, Blu-Tack, is an ideal material to use in this case. The…

Katsioloudis, Petros J. – Technology Teacher, 2010
The marine transport sector contributes significantly to air and water pollution, particularly in coastal areas. In the oceans, the threat to marine life comes in various forms, such as overexploitation and harvesting, dumping of waste, pollution, alien species, land reclamation, dredging, and global climate change. A congressional research report…

Sims, Margaret; Nagaddya, Teddy; Nakaggwa, Florence; Kivunja, Charles; Ngungutse, David; Ayot, Evelyn – International Research in Early Childhood Education, 2011
The voices of young people are beginning to be heard, but rarely are children living in poverty included in this research (Ridge, 2002). In this study, the authors used an interpretive approach that is informed by the phenomenological underpinning of the new sociology of childhood (Conroy & Harcourt, 2009; Schiller & Einarsdottir, 2009).…

Matyok, Tom – Qualitative Report, 2011
Investigating highly mobile labor populations presents researchers with unique challenges and opportunities. In this paper, I share my experiences and reflections in collecting international merchant seafarers' oral histories and propose to move the dialogue forward regarding the use of hybrid qualitative research practices. Seafarers are…

VanDorn, Daniel; Ravalli, Matthew T.; Small, Mary Margaret; Hillery, Barbara; Andreescu, Silvana – Journal of Chemical Education, 2011
There has been much interest in magnetite (Fe[subscript 3]O[subscript 4]) due to its utility in adsorbing high concentrations of arsenic in contaminated water. The magnetic properties of the material allow for simple dispersion and removal from an aqueous system. An inquiry-based laboratory has been developed that illustrates these unique…

Lee, Chwee Beng; Jonassen, David; Teo, Timothy – Interactive Learning Environments, 2011
This study examines the effects of the activity of building systems models for school-based problems on problem solving and on conceptual change in elementary science classes. During a unit on the water cycle in an Asian elementary school, students constructed systems models of the water cycle. We found that representing ill-structured problems as…

Hansen, Lexine Tallis – ProQuest LLC, 2010
International community development is a fertile area of research for environmental education scholars and practitioners. Although the community development field is well established, there is relatively little focus on education and learning in community development literature, especially in developing country settings. Particularly,…

DeKock, Roger L.; Schipper, Laura A.; Dykhouse, Stephanie C.; Heeringa, Lee P.; Brandsen, Benjamin M. – Journal of Chemical Education, 2009
We performed theoretical studies on the systems NH[subscript 3] times HF times mH[subscript 2]O, NH[subscript 3] times HCl times mH[subscript 2]O, with m = 0, 1, 2, and 6. The molecules with m = 0 form hydrogen-bonded adducts with little tendency to form an ion-pair structure. The molecule NH[subscript 3] times HCl times H[subscript 2]O cannot be…
