For seven weeks during the months of June and July, nearly 1300 middle and high school students attended San Antonio PREP (SA-PREP) 2013, a rigorous summer mathematics-based learning program offered at nine college and university locations across San Antonio. To ensure that the program is preparing students for careers in Science, Technology, Engineering, and Mathematics (STEM) locally, SA-PREP works with industry leaders and faculty researchers to provide student interactions with local businesses and research labs, emphasizing the importance of a STEM-based in education. For example, PREP collaborated with Maxim Integrated, a water fab (semiconductor fabrication plant), to introduce first-year PREP students to the semi-conductor field, the future of this industry and the employment opportunities that will become available to today’s youth. Students learned from Maxim engineers how everyday items they use as smartphones, tablets, computers, and medical devices are created through an experiment directly linked to the Logic course they had been studying. Year II students were exposed to the world of automotive manufacturing when they attended a field trip to Toyota Motor Manufacturing, Texas. The plant visit included representatives from Toyota officials and an interactive session where students learned the fundamentals of the Toyota method of continuous improvement “Kaizen” and respect for people through factory simulation building Lego trucks. Year IV students had the option this year of a nanotechnology track, offered in collaboration with the UTSA Department of Physics and Astronomy. Students taking the nanotechnology track interfaced with faculty members and were exposed to Helenita, the world’s most powerful electron microscope at UTSA’s Advanced Microscopy Laboratory. As a commitment to students and to assist in furthering their education, PREP’s institutional partners offered college scholarships totaling over $1.5 million to Year III and Year IV graduates with averages of 90 percent or better.
