Hershkovitz, Arnon; Baker, Ryan S. J. d.; Gobert, Janice; Wixon, Michael; Sao Pedro, Michael – Grantee Submission, 2013
In recent years, an increasing number of analyses in Learning Analytics and Educational Data Mining (EDM) have adopted a "Discovery with Models" approach, where an existing model is used as a key component in a new EDM/analytics analysis. This article presents a theoretical discussion on the emergence of discovery with models, its…

Sharp, David; Zhang, Mingqian; Xu, Zhenghe; Ryan, Jim; Wanke, Sieghard; Afacan, Artin – Chemical Engineering Education, 2008
A simple mixing of a hot- and cold-water stream at a T-junction was investigated. The main objective was to use mass and energy balance equations to predict mass low rates and the temperature of the mixed stream after the T-junction, and then compare these with the measured values. Furthermore, the thermocouple location after the T-junction and…

Masciocchi, Norberto; Galli, Simona; Sironi, Angelo; Dal Monte, Gabriella; Barea, Elisa; Salas, Juan Manuel; Navarro, Jorge A. R. – Journal of Chemical Education, 2008
The [Co(4-pyrimidinolate)[subscript 2](H[subscript 2]O)[subscript n]] species, which can be easily and selectively prepared by simple addition of aqueous solutions of the 4-pyrimidinolate organic ligand to Co(II) acetate (or nitrate) aqueous solutions (n = 4, 6) or by controlled heating of the hydrated phases (n = 0), proved to be versatile…

Rice, Charles V.; Giffin, Guinevere A. – Journal of Chemical Education, 2008
Semiconductor quantum dots are at the forefront of materials science chemistry with applications in biological imaging and photovoltaic technologies. We have developed a simple laboratory experiment to measure the quantum-dot size from fluorescence spectra. A major roadblock of quantum-dot based exercises is the particle synthesis and handling;…

Gordon, Jessica – Science Scope, 2008
Water is an essential resource for all living things. How we live on our watershed can impact water quantity and quality. It is important to recognize how humans alter watershed dynamics, but students often find it challenging to visualize watershed processes and understand how decisions that they make as individuals and together as a community…

Humpherys, Sean LaMarc – ProQuest LLC, 2010
Given the increasing problem of fraud, crime, and national security threats, assessing credibility is a recurring research topic in Information Systems and in other disciplines. Decision support systems can help. But the success of the system depends on reliable cues that can distinguish deceptive/truthful behavior and on a proven classification…

Nava, Emily Anne – ProQuest LLC, 2010
This dissertation investigates the relation between prosodic events at the phrasal level and component events at the rhythmic level. The overarching hypothesis is that the interaction among component rhythmic events gives rise to prosodic patterns at the phrasal level, while at the same time being constrained by the latter, and that in the case of…

Gear, Sabra B. – ProQuest LLC, 2010
The purpose of this study was to examine an activity-based intervention, dialogic reading with embedded explicit phonological awareness strategies, applied as a preventive approach by parents in their home settings located within a culturally and ethnically diverse urban region. This study investigated the effects of training parents to employ a…

Hsiao, E-Ling – ProQuest LLC, 2010
The aim of this study is to explore whether presentation format and prior knowledge affect the effectiveness of worked examples. The experiment was conducted through a specially designed online instrument. A 2X2X3 factorial before-and-after design was conducted. Three-way ANOVA was employed for data analysis. The result showed first, that prior…

Slover-Linett, Cheryl; Stoner, Michael – CURRENTS, 2010
Earlier this year, CASE formed a social media task force to explore what educational institutions are trying to achieve with social media presence and learn about social media engagements at member institutions. CASE, in partnership with mStoner and Slover Linett Strategies, in June launched a benchmarking survey on social media in advancement by…

Zable, Anthony C. – Physics Teacher, 2010
The concepts of Newtonian mechanics, fluids, and ideal gas law physics are often treated as separate and isolated topics in the typical introductory college-level physics course, especially in the laboratory setting. To bridge these subjects, a simple experiment was developed that utilizes computer-based data acquisition sensors and a digital gram…

Lavicza, Zsolt; Hohenwarter, Markus; Jones, Keith; Lu, Allison; Dawes, Mark – International Journal for Technology in Mathematics Education, 2010
In this paper, we will outline some results of an NCETM (National Centre for Excellence in the Teaching of Mathematics) funded project that aimed to establish a professional development network with an open-source mathematical software--GeoGebra--in England. During the past few years a large international user and developer community has formed…

Rueschemeyer, Shirley-Ann; Pfeiffer, Christian; Bekkering, Harold – Neuropsychologia, 2010
Words denoting manipulable objects activate sensorimotor brain areas, likely reflecting action experience with the denoted objects. In particular, these sensorimotor lexical representations have been found to reflect the way in which an object is used. In the current paper we present data from two experiments (one behavioral and one neuroimaging)…

Mosse, E. K.; Jarrold, C. – Journal of Intellectual Disability Research, 2010
Background: The Hebb effect is a form of repetition-driven long-term learning that is thought to provide an analogue for the processes involved in new word learning. Other evidence suggests that verbal short-term memory also constrains now vocabulary acquisition, but if the Hebb effect is independent of short-term memory, then it may be possible…

Koriat, Asher; Ackerman, Rakefet – Developmental Science, 2010
Research with adults indicates that confidence in the correctness of an answer decreases as a function of the amount of time it takes to reach that answer, suggesting that people use response latency as a mnemonic cue for subjective confidence. Experiment 1 extended investigation to 2nd, 3rd and 5th graders. When children chose the answer to…
