TeKnowledgy Greenhouse: An Engineering and Education Learning Community. Awarded by National Science Foundation. Grant is a 1-year planning grant (October 2003-2004) for the Colleges of Education and Engineering at NC State University to develop a TeKnowledgy Greenhouse to foster a learning community that can draw upon the strengths of both fields and generate innovative solutions for the engineering education of K-12 and undergraduate students. As a greenhouse, we will operate as an incubator of intellectual endeavors that can produce knowledge for utilizing the power of technology to provide education for students in K-12, undergraduate engineering, and preservice teacher education. A one-year planning grant will allow us to establish a community culture for faculty and undergraduate students at a research-intensive university to work together on educational issues of teaching, research, and societal needs. In addition, the planning grant will allow for a type of “existence proof” of what is possible as we design, prototype, and test initial products for engineering education. PI: Stohl, Co-PIs: Bill Deluca, Steve Walsh, & Tom Miller. ($100,000).

University of Virginia Continuing Education 1997-2000
        Developed a 3-credit graduate course on the "Teaching and Learning of Algebra," including a comprehensive course packet. Most algebraic concepts are developed through pattern-based situations and utilize real world applications, concrete materials, and technology tools. I conducted training sessions for other adjunct faculty teaching the course.

Center for Technology and Teacher Education    1997-present
        Currently part of a team developing materials to help preservice and inservice teachers learn how to effectively integrate technology into middle and secondary mathematics classes.  The materials utilize Microsoft Excel, The Geometer's Sketchpad, MicroWorlds (Logo), the WWW, java applets, and graphing calculators.  Materials have been disseminated for use in mathematics content and methods courses at other colleges and universities. Sample materials and our guidelines for development can be viewed online.

Virginia Department of Education  1997-1998
        Collaborated with several mathematics educators to design an institute for enriching K-5 teachers' knowledge about patterns, functions and algebra.  Piloted the 3-day institute twice during 1997.  Materials distributed through the Virginia Department of Education, 1999.

School-University Research Network    1996
        Designed three activity packets for teachers to improve the teaching and learning of algebraic concepts in upper elementary, middle school, and Algebra I. The activities were designed to correlate with the 1995 Virginia Standards of Learning.  Materials distributed to teachers in 14 school divisions in Virginia.

 Probability Explorer    1998-present
        Designed and developed a microworld for elementary and middle school students to explore probability and rational number concepts with such devices as coins, dice, spinners, and marbles as well as real world events such as the weather, sports and the lottery. (microworld developed in Visual Basic.)

Dominoes and Dice    1997-98
        Designed and developed a microworld to help elementary and middle school students learn probability concepts.  The environment is designed to be open-ended and enhance students' understanding with concepts such as sorting, classifying, randomness, fair, empirical and theoretical probability, combinations, permutations, and graphing.   An instructional unit to accompany the software was written by H. S. Drier and P. White. (microworld developed in Oracle Media Objects)
