Multitarget tracking in distributed sensor networks
In this paper, we provide a survey of techniques for tracking multiple targets in distributed sensor networks and introduce some recent developments.

Designing Networked Handheld Devices To Enhance School Learning
We begin by discussing a simple but important factor: networked handhelds can allow a 1:1 student: device ratio for the first time, enabling ready-at-hand access to technology throughout the school day and throughout the learner’s personal life.

Can A Technology-Enhanced Curriculum Improve Student Learning Of Important Mathematics?
This project investigated the scale-up of an innovative integration of technology, curriculum, and teacher professional development aimed at improving mathematics instruction in grades 7 and 8.

Microstructure foundations of high carrier mobility in polymers
We combine complementary microstructure measurements including polarized absorption spectroscopies (infrared, visible, and X-ray), scanning probe techniques, and X-ray diffraction (XRD) to investigate the microstructure details of polymer semiconductors for organic thin film transistors (OTFTs).

Comparing theory and hypotheses to electric force microscope data: are we thinking about injection, trapping, and transport correctly in organic electronic materials?
In this talk we will show that ultrasensitive cantilevers can likewise measure the local charge diffusion constant via the effect of the associated electric field fluctuations on cantilever frequency and ringdown time.

Analysis of Morph-Based Speech Recognition and the Modeling of Out-of-Vocabulary Words Across Languages
We analyze subword-based language models (LMs) in large-vocabulary continuous speech recognition across four “morphologically rich” languages: Finnish, Estonian, Turkish, and Egyptian Colloquial Arabic.

Assessing Students. Performance Longitudinally: Item Difficulty Parameter Vs. Skill Learning Tracking
We are engaged in an effort to investigate if we can do a better job of predicting a large scale test (MCAS) by modeling individual skills in different grain-sized skill models than by using item difficulty parameters induced from traditional Item Response Theory models, on which computer adaptive testing relies.

Towards Live Informing and Automatic Analyzing of Student Learning: Reporting in the Assistment System
In this article we describe the types of reports that we have designed and implemented that provide real time reporting to teachers in their classrooms. Experiment analysis tools are available to facilitate researchers to carry out randomized controlled learning experiments so that they are able to compare different tutoring strategies.
