In this paper we propose a new electronic whiteboard system for teaching fractions, a fundamental math topic that is often problematic for students. A field interview with an elementary school teacher and an examination of a math textbook that is common in Japanese public schools produced a set of usage scenarios that motivated our tool. The result, FractionSketch, allows teachers to sketch sha...

In this paper we introduce WISEngineering, a new curriculum delivery, assessment, and feedback system that uses engineering design to teach science, technology, engineering and math (STEM) concepts to middle school and high school students. WISEngineering is a free, opensource environment that supports STEM learning by guiding students through informed engineering design projects 1 . WISEnginee...

Our previous work demonstrated that abacus-based mental calculation (AMC), a traditional Chinese calculation method, could help children improve their math abilities (e.g. basic arithmetical ability) and executive function (e.g. working memory). This study further examined the effects of long-term AMC training on math ability in visual-spatial domain and the task switching component of executiv...

Although using diagrams is generally considered one of the most effective strategies for solving math word problems, research and educational practice reports indicate that students lack spontaneity in their use of diagrams. In an attempt to address this problem, the present study investigated the hypothesis that creating situations whereby students have to teach other students how to solve mat...

We report on a three-year project to make data-driven improvements in the mathematics placement process at the University of Northern Colorado. We began by analyzing fall 2007 placement recommendations for a sample of N=1466 first-year students to the university. These recommendations came from brief faculty-student interviews during summer orientation sessions in which math instructors suggest...

BACKGROUND The Eating and Cooking Healthy (TEACH) Kitchen was founded at the Medical College of Georgia in 2015 as a nutrition-based intervention to combat the high prevalence of obesity and obesity-related chronic diseases in the area of Augusta, Georgia. Despite the importance of diet in the management of chronic diseases, inadequate nutrition education among patients and healthcare providers...

Abstract: The digital signal processing revolution began around 1980 as the first dedicated digital signal processors began to appear. Since that time DSP has been incorporated into just about every aspect of modern electronics. Oscilloscopes are no exception. Digital storage oscilloscopes have almost totally replaced analog oscilloscopes. They use DSP in acquisition modes, averaging, interpola...
