The purpose of this study was to determine what knowledge of energy systems the students currently enrolled in Introductory Power Mechanics courses in the public high schools of Indiana possess, where they acquired such knowledge, and what the instructors' emphases in the course were.Two questionnaires were used in this study. The first, a thirty-item questionnaire, was utilized to determine what the students know about energy systems and where they learned what they know. The second one was a nineteen-item questionnaire to determine the instructors' course emphases.The null hypotheses were tested using a one way analysis of variance and a Scheffe Test. The .050 level of significance was used as the critical probability level for rejecting the hypotheses. |
