Teaching To Develop Perspective, Skills, Confidence, And Identity As Problem-Solving Engineers, Russell Kirk Pirlo Sep 2023

Teaching To Develop Perspective, Skills, Confidence, And Identity As Problem-Solving Engineers, Russell Kirk Pirlo

Research and Reflection on Learning and Teaching in Higher Education

The “core” of an engineering degree program typically comprises the concepts, equations, and technical skills needed, as well as their practical application to common problems of the profession. This core is then divided into the “content” that must be covered in each course. It is widely recognized, however, that successful individuals do not thrive as professionals on content alone. Thus, there is significant and increasing emphasis across higher education to “educate the whole person.” These efforts aim to develop “deep” qualities like grit, critical thinking, perseverance, learning from failure, valuing diversity, teamwork, leadership, curiosity, recognizing opportunity, creating value, and acting …

Systems Thinking Applied To Higher Education Curricula Development, Reza Rahdar, Mark London, Yuetong Lin, Hong Jiang

Publications

Systems Thinking (ST) is a general and yet nebulous term that describes an approach to understanding and working with complexity in the real world. ST seeks to evaluate different behaviors of individual system elements when they operate in isolation as opposed to when they are integrated as part of a larger system and placed within a particular operating environment. The education environment consists of multiple systems with different digital content, learning goals/outcomes that serve different stakeholders including teachers, learners, and administrators. The inherent complexity and interaction among these various educational system elements and functions make this environment a worthy candidate …

Re(Engineering) Student Success: Constructing Knowledge On Students’ Experiences In Engineering Education Programs To Encourage Holistic Student Success, Shaylin Williams

Theses and Dissertations

If a group of engineering deans were asked whether students at their institutions were successful and why, what information might they immediately or subconsciously use to measure or gauge the engineering students’ success? If only academic performance outcomes like GPA, individual course grades, or graduation rate race to their minds, then their rationale aligns with the majority of researchers. My research seeks to shift the mindset that frames engineering student success mainly within the boundaries of academic performance measures. By measuring students’ perceived autonomy, competence, social integration and relatedness within their programs, and aspirations after graduation, one can more accurately …

Using Self-Efficacy Theory To Design Arduino Instruction For Novices: A Replication Study, Donald M. Johnson, Michael Pate, Christopher M. Estepp, George Wardlow May 2023

Using Self-Efficacy Theory To Design Arduino Instruction For Novices: A Replication Study, Donald M. Johnson, Michael Pate, Christopher M. Estepp, George Wardlow

Journal of Research in Technical Careers

A replication study was conducted to determine the effectiveness of an instructional treatment based on self-efficacy theory when used with novice Arduino microcontroller users. Students (n = 32) in an introductory university agricultural systems technology course participated in a lesson on Arduino microcontrollers, circuit breadboarding, and Arduino programming which included four hands-on practice tasks, designed to provide students with positive mastery, vicarious and social persuasion experiences. Next, students completed a laboratory activity and were provided additional opportunities for mastery, vicarious, and social persuasion experiences. The one-group pretest-posttest design indicated the instructional treatment had significant (p < .001) and large effects in increasing students’ interest in Arduino, breadboarding self-efficacy, programming self-efficacy, and Arduino knowledge. These findings were consistent with the original study and provided additional evidence for self-efficacy theory as an effective model for developing instruction for novice Arduino users. Students’ written comments provided additional insight concerning the instructional treatment.
