In an effort to change unsafe tractor operating behaviors among Appalachian youth resulting from practices and habits learned through a socialization process (termed an "apprenticeship of observation"), this study implemented a four-part intervention in high school agricultural education classes that included implementation of a cost-effective rollover protective structure (CROPS) curriculum. The curriculum included farm safety information, specific NIOSH plans for CROPS construction, and procedures for CROPS installation on unprotected tractors. In this exploratory study, pre- and post-assessments were conducted using theory of planned behavior (TPB) constructs to measure changes in four factors that influence changes in learner behavior: learner attitude, perceived social norms, behavioral control, and perceived behavioral intention. Students' perceived knowledge and skills gained through the intervention were also measured because they are integral components in assessing the effectiveness of a curriculum intervention. Participants (N = 83) were high school students from seven schools in three states in the Appalachian region. Findings revealed statistically significant differences in student attitudes toward the use of life-saving CROPS and in perceived knowledge and skills gained through the curriculum implementation. The CROPS curriculum can be an effective intervention effort for addressing the social and behavioral effects of farm youths' apprenticeships of observation by creating more positive attitudes and learning outcomes among youth at risk for tractor rollover fatalities. Recommendations are provided for expanding the applications of the curriculum intervention and the TPB constructs.
