The effectiveness of different methods of instruction has been discussed since the early years of formal education systems. Lecture has been deemed the most common method of presenting information to students (Kindsvatter, Wilen, & Ishler, 1992; Waldron & Moore, 1991) and the demonstration method has been symbolized as the most effective tool developed for teaching (Seevers, Graham, Gamon, & Conklin, 1997). Engaging students is paramount to allowing instructors to expand student knowledge levels. The purpose of this study was to determine if the Arkansas Secondary Biodiesel Education Program (ASBEP) over alternative fuels had an effect towards student interest. A significant difference was found between student interest in method of presentation, t(7) = 8.29, p < 0.05. Furthermore, a strong positive correlation (r = 0.73) was found between posttest scores and student tinkering self-efficacy. Tinkering self-efficacy was also found to be positively and significantly correlated with method of instruction. Through understanding perceptions held by student being taught through different methods, instructors can capitalize and further knowledge acquisition by students.
