Developing an Instrument to Measure Engineering Design Self-Efficacy: A Pilot Study
Keywords: self-efficacy, engineering design
The following pilot study is an investigation of how to develop an instrument that measures students’ self-efficacy regarding engineering design. 36 items were developed and tested using three types of validity evidence. First, the content of the instrument was tested to ensure that the full domain (each subdimension) of the engineering design process was represented. Second, the instrument was tested for whether responses to the instrument could identify groups with various levels of engineering design experience. Finally, theoretical connections between motivation, expectancy for success, and anxiety were tested to determine their appropriateness in the measurement of self-efficacy. Results confirmed an accurate reading of engineering design self-efficacy for 82 volunteer respondents with diverse engineering expertise.
Self-efficacy is a motivational construct regarding an individual’s belief or judgment in their capability to organize and execute courses of action for a given domain-specific task.[1, 2] An individual’s self-efficacy plays a crucial role in their ability to conduct a particular task; however, self-efficacy toward engineering concepts is rarely analyzed. Information about engineering student levels of self- efficacy on engineering tasks can be useful for educators to plan and structure engineering courses.
The following paper describes an exploratory pilot study conducted to inform the development of an instrument designed to identify self-efficacy toward engineering design. Engineering design, or the process used to devise a system, component, or process to meet a desired need, was chosen as the focus because of its importance in the field of engineering.
Instrument development was guided by three questions:
1. How should the engineering design domain be represented? 2. Does the instrument predict differences in self-efficacy held by subjects with a range of engineering experience? 3. Does the instrument predict relationships among constructs adopted in this study?
These questions are explored through three forms of validity evidence : content, criterion-related, and construct. The paper begins by defining each validity type to establish the necessity for each validation step. Previous research in the realm of
