Nanotechnology Experiences for Teachers and Students, Student Experiences and Outcomes

Abstract

The Nanotechnology Experiences for Students and Teachers (NEST) program aimed to increase nanotechnology content knowledge, scientific research knowledge, and understanding of nanotechnology among high school students while fostering career readiness in nanotechnology-related fields. The program, offered for four consecutive summers with a two-week session each summer, included the following experiences: research experience and knowledge of careers in nanotechnology, hands-on laboratory experiences in inquiry-based science and the engineering design process and discover innovative technologies all while generating awareness and interest in emerging workforce opportunities. In total, 123 students [F=50, M=73; White=29; African American/Black=41, Hispanic=13, Asian=30, Other=10) participated in the program. The program was focused on recruiting students from low-income and underrepresented populations. This paper details the two-week intervention as it progressed over the course of four years. A formative and summative mixed-methods program evaluation was conducted to better understand and promote practices that increased students' motivations and capacities to pursue careers in fields of science, technology, engineering, or mathematics (STEM). Each year, both the implementation and evaluation teams reviewed findings and discussed relevant changes to the program the following year. While each year of NEST included an introduction to nanotechnology, visits to existing laboratories, and hands-on activities, we detail where there were successes and failures, changes made to the program each year, and the associated student-level outcomes. For example, early findings found outcome issues related to race/ethnicity and content knowledge gains below expectations.
