Financial Literacy is one of the subject areas taught in Family and Consumer Sciences (FCS) courses which is not graduation requirement for high school students across Pennsylvania. The problem of practice I addressed is that Greensburg Salem High School (GSHS) students are graduating without the financial literacy knowledge and skills to become successfully independent adults. Three inquiry questions that guided my dissertation in practice are: (1) "How is student financial literacy knowledge impacted by a simulation activity compared to the Next Gen Personal Finance (NGPF) curriculum and teaching practices?"; (2) "What are the teacher's perceptions of implementing the simulation activity compared to the standard curriculum/practices?"; and (3) "Was the teacher able to implement the Budget Project simulation activity with high levels of fidelity?" Two GSHS Financial Literacy classes participated in the inquiry project: one group of students completing a new Budget Project simulation activity and the other group completing the standard NGPF Budgeting Unit. Measures included a student pre/post survey to assess their financial literacy knowledge, an individual interview with the intervention classroom teacher, and observations of intervention implementation via a fidelity checklist. The descriptive statistics from the survey and fidelity data, combined with the codes from the teacher interview, revealed positive results in both the intervention teacher and the students. Students had higher financial literacy knowledge retention and understanding after completing the Budget Project, and the teacher reported ease of use and productive experiences with students. Future implications include modifying the GSHS Financial Literacy curriculum to include more simulation activities, including the Budget Project, and enhancing professional development for educators teaching financial literacy.
