Research Interests

Model-Development Sequences - Employing design research methodologies to the development, implementation, and assessment of engineering-based modeling activities, especially in first-year engineering education settings. Research focuses include student problem-solving and teaming skills development; faculty and teaching assistant development; and frameworks for developing activities, implementing them in a course, and assessing quality of student work.

Evaluation of Education Technology - Developing and/or evaluating computer-based learning modules and their implementation. Examples:
  • Quantitative cellular biology learning modules in an engineering one-credit hour supplement to a sophomore level cellular biology course.
  • M-Tutor in a first-year engineering problems solving and computer tools course.
  • FOODS-LIB and user's manual learning modules in a senior level food process engineering course.
Advanced Engineering Content in First-Year Education - Developing and assessing the impact of mechanisms (e.g. learning modules, modeling activities, courses, research experiences) for making advanced engineering content (e.g. nanotechnology) accessible to first-year students.
