Over the past three years we have been exploring not only how computational thinking impacts the first-year student experience but also persistence to graduation and enculturation to engineering. Students matriculate to engineering degrees with different academic preparation in mathematics and computing. We began our work by designing a computational thinking diagnostic that can be administered to students as they enter the engineering program in order to determine student's ability to use the principles and practices that are learned by studying computing. We can report that 3584 students were participants during the development of the Engineering Computational Thinking Diagnostic (ECTD) and the last 469 were involved in exploratory and confirmatory analysis. 

Computational thinking is an important skill in the formation of engineers. Many schools of engineering include a programming course during the first-year. In 2019, NSF funded the “Collaborative Research: Research in Improving Computational Thinking in the Formation of Engineers, a Multi-Institutional Initiative.” The project’s goal is to improve the way computational thinking is taught at the college engineering level via the understanding of the multiple factors that affect computational thinking development. The project’s research questions are: · Research Question 1: How does the integration of computing into the foundational engineering courses affect the formation of engineers? · Research Question 2: In what ways do social identities (e.g. gender, ethnicity, first generation college attending, socioeconomic status), choices (e.g. major, transfer status), and other factors impact the engineering student experience with computational thinking? · Research Question 3: In what ways do computational thinking skills develop over time in engineering students? In order to respond to these questions, the research team developed a Computational Thinking Hybrid Framework, an Engineering Computational Thinking Diagnostic (ECTD) and a Position of Stress Questionnaire. Amid COVID-19, the advances of the project include approximately 2000 participants responding to the diagnostic during the Fall of 2019 and the Fall of 2020. With this participation, two cycles of validation have taken place for the ECTD and results are presented in this poster session. The factors validated in this diagnostic are (1) Abstraction, (2) Algorithmic Thinking and Programming, (3) Data Representation, Organization, and Analysis, (4) Decomposition, and (5) Impact of Computing. The positions of stress have been collected for the Fall of 2020 and preliminary results are also presented in this session.
