Integrating a Nanologic Knowledge Module Into an Undergraduate Logic Design Course

This work discusses a knowledge module in an undergraduate logic design course for electrical engineering (EE) and computer science (CS) students, that introduces them to nanocomputing concepts. This knowledge module has a twofold objective. First, the module interests students in the fundamental logical behavior and functionality of the nanodevices of the future, which will motivate them to enroll in other elective courses related to nanotechnology, offered in most EE and CS departments. Second, this module can be used to let students analyze, synthesize, and apply their existing knowledge of the Karnaugh-map-based Boolean logic reduction scheme into a revolutionary design context with majority logic. Where many efforts focus on developing new courses on nanofabrication and even nanocomputing, this work is designed to augment the existing standard EE and CS courses by inserting knowledge modules on nanologic structures so as to stimulate student interest without creating a significant diversion from the course framework.

Integrating Laboratory Activity Into a Junior High School Classroom

This paper presents a wind power system laboratory activity and an outline for evaluating student performance in this activity. The work described here was to design and implement the laboratory to assist teachers in achieving the teaching objective of this activity. The laboratory teaching activities introduce energy sources, wind energy technology, electricity storage, and wind power system testing. The wind power system testing activity includes eight topics: setting up the experimental module, operating instruments, wind velocity measurement, rotor diameter activity, wind speed activity, blade angle activity, blade number activity, and data summary. These laboratory activities were first introduced in a Taiwanese junior high school in 2007. This laboratory activity effectively introduced students to wind energy technology through activity participation. The objective of this activity is for the students to gain not only an understanding of the concept of wind power electricity generation, but a greater confidence in investigating, questioning, and experimenting with renewable energy ideas. The students are able to relate the experiments to electronic and computer engineering.

A Sustainable Model for Integrating Current Topics in Machine Learning Research Into the Undergraduate Curriculum

This paper presents an integrated research and teaching model that has resulted from an NSF-funded effort to introduce results of current Machine Learning research into the engineering and computer science curriculum at the University of Central Florida (UCF). While in-depth exposure to current topics in Machine Learning has traditionally occurred at the graduate level, the model developed affords an innovative and feasible approach to expanding the depth of coverage in research topics to undergraduate students. The model has been self-sustaining as evidenced by its continued operation during the years after the NSF grant's expiration, and is transferable to other institutions due to its use of modular and faculty-specific technical content. This model offers a tightly coupled teaching and research approach to introducing current topics in Machine Learning research to undergraduates, while also involving them in the research process itself. The approach has provided new mechanisms to increase faculty participation in undergraduate research, has exposed approximately 15 undergraduates annually to research at UCF, and has effectively prepared a number of these students for graduate study through active involvement in the research process and coauthoring of publications.
