The major objectives of this Engaging Girls in Ubiquitous Intelligence and Computing (GUIC) project are to: 1) enhance secondary female students’ academic self-concepts in computing and engineering fields through a constructivist learning environment; 2) enhance secondary female students’ knowledge, skills, and interests in these fields; 3) increase the number of secondary female students’ participating in STEM competitions; and 4) investigate the factors that influence female students’ career choices in STEM and ICT fields. The major activities in each year include: 1) five-week GUIC Summer Camp to engage secondary female students in learning Arduino/C++ Programming and developing engineering projects, 2) one-week Spring Mentor Training Workshop to train teacher and UNLV student mentors, and 3) two-day Fall STEM Competition Workshop to promote STEM teachers to organize teams to participate in STEM competitions. From 2021 to 2023, we have engaged total 122 secondary female students from 53 CCSD middle & high schools (including 21 Title 1 schools) in GUIC Summer Camp. These students took three-week courses in Arduino & IoT and robotics designs then developed engineering projects in two weeks in a tiered team co-mentored by STEM teachers and UNLV engineering students. Through the Mentor Training Workshop, we have trained total 46 mentors (including 21 teacher mentors). The STEM Competition Workshop engaged total 22 STEM teachers. Total 27 STEM competition teams were supported.
