This study investigated the usefulness of providing successful and unsuccessful example solutions in enhancing students' technological problem-solving efficiency. Prior research exploring worked example solutions indicated improved problem-solving efficiency when solutions were structured in a fashion that decreased the amount of extraneous cognitive load and increased the amount of germane cognitive load as specified by cognitive load theory. Fifty-one 7th and 8th grade students enrolled in technology education courses were selected from one school in the southwest region of Virginia. Participants completed three technological problem-solving tasks that included elevated load, cantilevered weight, and energy absorption using supply kits containing simple modeling materials. Problem-solving efficiency was determined by combining the amount of elapsed time across all three tasks. A 3 x 3 mixed factorial ANOVA was used to analyze the data. Data analysis revealed trends similar to worked example research in mathematics and science, but no significant difference among the three groups was found in this study. / Ph. D.

The purpose of this study was to compare the effect of a computer simulation activity versus a hands-on activity on students' product creativity, originality, and usefulness. Fifty-eight middle school technology education students from Northern Virginia participated in the study. Subjects were randomly assigned to either a computer simulation or hands-on treatment group. The computer simulation group used a Lego-type brick simulator to construct creative products on the computer; whereas, the hands-on treatment group used real LEGO® bricks to construct their creative products. The hands-on groups' products were collected by the researcher and copied into the computer simulation program. Both groups' products were printed using a color printer. The printed products were evaluated by expert judges using a creative product semantic differential scale. This study showed that there was no significant difference in product creativity scores among the computer simulation and the hands-on treatment group. The null hypothesis was accepted. Findings suggested that it was possible to use a computer simulation activity in place of a hands-on activity and still maintain product creativity, originality, and usefulness. / Ph. D.

The purpose of this study is to collect information documenting Utah technology education teachers' acceptance of an emphasis on engineering content in technology education. The Stages of Concern Questionnaire (SoCQ) was used to determine the level of acceptance of this change. It was found that a majority of technology and education teachers are more concerned about other unidentified tasks, activities or initiatives than they are about the addition of engineering content to their classes. They were also shown to be concerned with being able to organize, manage, and schedule the change effectively and were found to be least concerned about evaluating student outcomes including performance and competencies. Utah teachers were polarized with respect to collaborating and coordinating with others with regards to engineering.
