This study investigated the influence of a four-week career unit course on the career content knowledge acquired by adult students and their attitude toward career counseling using a flipped classroom model of instruction. In this mixed-method study, a sample population of adult students enrolled in the career course through an Adult Education Site and received the four-week career unit. A sequential explanatory mixed method design was used. Students completed the two following pre-tests: 1) on learning outcomes from the career course unit and 2) on items from the attitudes toward career counseling scale (ATCCS). Students viewed pre-recorded lectures and completed corresponding activities outside of class to prepare for the virtual synchronous class meetings due to the COVID-19 pandemic. The topics of instruction included the career planning unit, which comprised practical exercises focusing on labor market data, career assessments, and resume development. At the end of the course, all students completed a post-survey. The data obtained from both the pre-test and post test was statistically analyzed using a one-way MANOVA with repeated measures. Upon completion of the analyses and the interpretation of the results, recommendations for future research were given.
