1. Advancing the Complex Product Design Using Virtual Reality Techniques (Funded by National Science Foundation)
The research goal is to advance the ability of complex product design especially freeform shape modeling with Virtual Reality techniques. In pursuit of this goal, the research objective is to investigate a virtual sculpting modeling and simulation technique for freeform geometry design. Freeform models have wide applications in the aerospace, automobile, mold/die making, biomedical products etc. The research approach is to apply virtual sculpting method by interactively carving a workpiece using a virtual tool. Boolean operations between the model and the tool are executed to change the geometry and materials of the design model simultaneously. Haptic interface is incorporated to reflect the interaction between the tool and the model during sculpting process. The virtual sculpting process is then integrated into the large scale PowerWall virtual environment.
2. Building a Learner-centered Cyberlearning Environment in Computer-Aided Design Education (Funded by National Science Foundation)
The major goals of this project are to enhance the students’ learning of computer-aided design (CAD) and promote their life-long learning skills and cultivate positive engineering attitudes by building a learner-centered cyberlearning environment.
3. Widening Implementation of Evidence-Based Pedagogies in STEM Education (Funded by US Department of Education)
The overarching goal of this project is to increase the number of minority students, particularly minority women, in STEM fields by transforming the culture of STEM education in Prairie View A&M University (PVAMU). The project has the following specific objectives: (1) Transforming the perception of STEM faculty on the adoption of evidence-based pedagogies; (2) Activating participating STEM faculty’s self-reflection and meta-cognition in evidence-base pedagogies by fully engaging them in educational design and research; (3) Improving students’ learning in the first two year of college; (4) Increasing the number of minority students, particularly minority women, in STEM fields.
