2014 Worthington Distinguished Scholars
"Fostering Story-Time Mathematical Discussions with Young Children"
This award will enable the development and implementation of a toolkit to facilitate math discussions with young children through shared reading experiences during story time in Seattle Public Libraries. The investigators have developed a process to mathematize the literature for use with young children, based upon research conducted in kindergarten classrooms. This research has resulted in multiple conference and invited presentations and appeared in a nationwide practitioner journal for teachers. By expanding their study of integrating math discussions into shared reading experiences beyond the school setting, the investigators hope to more effectively reach a diverse population.
"Development of a low power consuming, flexible, large-area organic light emitting diode (OLED) with enhanced light extraction efficiency"
Switching to light-emitting diode (LED) lighting over the next two decades could save the U.S. about $250 billion, reduce electricity consumption by almost 50% and avoid 1.8 billion metric tons of carbon emission. Organic light emitting diodes (OLEDs) are an emerging technology with the potential to offer low cost, bright and lightweight display panels in a highly flexible, virtually shatter-proof form. Dr. Choi's research intends to develop a flexible, large area substrate with integrated micro lens structures and thick metal grids to enhance light out-coupling efficiency, improve emission uniformity, and reduce power consumption. In November, Dr. Choi will present this research at the ASME 2014 International Mechanical Engineering Congress & Exposition (IMECE 2014) in Montreal.
