Technical workshops for inservice teachers may help fill this gap. This study investigated the effects of a one-day applied hydraulics workshop on teachers’ (n = 22) self-efficacy and intent to teach hydraulics. Prior to the workshop, a majority of teachers had a negative perception of their understanding of hydraulic concepts and their ability to teach hydraulics. Upon completion of the workshop, a majority of respondents had positive perceptions of their understanding of hydraulics concepts and their ability to teach hydraulics. Teachers’ participation in the workshop resulted in a statistically significant (p < .001) and large (Cohen’s d = 1.65) overall increase in self -perceived understanding and ability to teach hydraulics. In addition, the percentage of teachers indicating they planned to teach hydraulics in one or more courses increased from 36.4% prior to the workshop to 87.3% after the workshop.
