Combinatorial screening of the effect of temperature on the microstructure and mobility of a highperformance polythiophene semiconductor
Using a gradient combinatorial approach, the authors report the effects of temperature on the microstructure and hole mobility of poly(2,5-bis(3-dodecylthiophen-2yl)thieno[3,2-b]thiophene) thin films for application in organic field-effect transistors.

Developing Fine-Grained Transfer Models In The ASSISTment System
In this article, we describe our attempt to create a fine-grained transfer model for 8th grade math based on the skills needed to take the Math MCAS exam and how we use this model in a web-based intelligent tutoring system called the ASSISTment system.

A Web Based Authoring Tool for Intelligent Tutors: Blending Assessment And Instructional Assistance
To help teachers make better use of their time, we are integrating assistance and assessment by utilizing a web-based system (“Assistment”) that will offer instruction to students while providing a more detailed evaluation of their abilities to the teacher than is possible under current approaches.
