The purpose of this study was to examine the development of the Engineering Identity Development Scale (EIDS), an instrument designed to assess elementary school students' identity development in engineering. This study describes a three-phase approach to item construction, administration, and the gathering reliable and valid evidence for scores on the EIDS.

Background: Teacher self-efficacy has received attention because of its direct relationship with teachers’ classroom behaviors. Since engineering has been increasingly introduced in K-12 (precollege) education, development of an instrument to measure teachers’ self-efficacy in the context of teaching engineering has been needed. Purpose (Hypothesis): This study reports the development and validation of the Teaching Engineering Self-Efficacy Scale (TESS) for K-12 teachers. Design/Method: The items for the TESS were constructed through a comprehensive review of the literature regarding K-12

BACKGROUND If we are to effect change in teacher practices and decision making regarding instruction, college preparation, and career success in engineering, then knowledge of teachers’ beliefs and expectations about engineering needs to be understood. PURPOSE(HYPOTHESIS) The primary purpose was to develop a statistically reliable survey instrument to document teachers’ beliefs and expectations about pre-college engineering instruction, college preparation, and career success in engineering, called the Engineering Education Beliefs and Expectations Instrument (EEBEI), and to compare teachers’
