A CRISPR workshop series for diverse learners in Hawai'i: design, implementation, and outcomes across 3 years

CRISPR genome editing has revolutionized modern biotechnology, yet access to experiential training remains limited, particularly in underrepresented and geographically isolated regions. This report describes the design, implementation, and evaluation of a CRISPR workshop series conducted over three consecutive years supported by the USDA Higher Education Challenge program and hosted at the University of Hawai'i at Mānoa. Conducted over three consecutive summers (2023-2025), the week-long, hands-on program engaged high school students, undergraduates, graduate students, educators, and community members through molecular-biology experiments, bioinformatics modules, and structured discussions on ethics and societal implications. Pre- and post-workshop assessments demonstrated significant learning gains, with mean quiz scores increasing from 58.7% to 80.2%, and all respondents (100%) reported increased confidence in genome-editing techniques. These results highlight the workshop's effectiveness in enhancing CRISPR literacy and supporting the development of scientific self-efficacy across diverse audiences. The initiative provides an adaptable workshop model and implementation guidance that other institutions can adopt to expand hands-on CRISPR training in diverse learning contexts.
