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.

An Investigation Into Perceptions, Expectations, And Development Of Professional Skills In Engineering Students, Morgan Kathryn Green

Theses and Dissertations

Upon graduation from an undergraduate institution, engineering graduates are expected to have a baselevel skill in technical skills related to their discipline. Teaching technical skills comes naturally to engineering programs as the conceptual understanding of the material form the foundation of engineering ability. However, engineering graduates also are expected to have a baselevel of professional skills, which are more subjective in nature and do not have a standardized approach for teaching or assessing them at the undergraduate level. An investigation into current perceptions of professional skills by relevant parties is an initial step in providing more structure to professional skills …

Where Did They Come From? Why Did They Go? How Engineering Students’ Perceptions Cultivate Experiences And Influence Behaviors, Sara Campbell Vick

Theses and Dissertations

Engineering undergraduate students have opinions and perceptions of engineering disciplines and engineering undergraduate students do not always matriculate and graduate in precisely the same discipline. Understanding how these two characteristics of engineering undergraduate students interact to inform behaviors is important for engineering educators and administrators to increase and improve recruitment and retention among their students.

This dissertation approached each characteristic of engineering students, first separately and then together. A nationwide survey of undergraduate engineering students found significant differences in how students perceive various engineering disciplines along several paired-term anchored scales. These differences were equally significant when scores were considered in …

A Questionnaire Survey Of Student Engagement Among First-Generation College Students In Engineering, Abigail Lehto

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

First-generation college (FGC) students are defined as students whose parents do not have a bachelor's or graduate degree. FGC students tend to face more overall challenges in the college environment than their continuing-generation counterparts. Often, FGC students have lower grade-point-averages (GPAs) and are less likely to graduate than their peers. In majors like engineering, the struggles that first-generation college students face can be further magnified. This quantitative study examines the activities FGC students in engineering engage in based on the National Survey of Student Engagement (NSSE). Questions from the NSSE cover different educational activities and are categorized into ten educational …

There were 25 participants in the study who were either district personnel or secondary teachers. All school districts in the study incorporated …

Promoting Skills In Children And Teens With Autism Spectrum Disorder Through Play And Steam, Meaghan Mcleod Mozingo, Krzysztof J. Rechowicz

Modeling, Simulation and Visualization Student Capstone Conference

Individuals with autism spectrum disorder (ASD) have a low employment rate. This is caused by a lack of support from employment resources and the negative stigma associated with common characteristics associated with ASD. With limited career-building activities and events, it is difficult for individuals with ASD to identify their skills, strengths, and career opportunities. Parental support is crucial when seeking employment opportunities for their children. Through the use of play, children with ASD engaged and explored their skills with science, technology, engineering, arts, and math-centered activities. This paper highlights the events and shows the proposed redesign for an additional workshop.

Simulating Function Generators And Oscilloscopes In A Virtual Laboratory Environment, Yiyang Li, Yuzhong Shen, Charles I. Sukenik

Modeling, Simulation and Visualization Student Capstone Conference

This paper discusses the development of a virtual laboratory for simulating electronic instruments commonly used in science and engineering courses, such as function generators and digital storage oscilloscopes. Mathematical equations are used to represent continuous signals and ensure signal integrity, while C# delegates are adopted to enable communication between simulated devices. The approach allows for loose coupling between software components and high cohesion of individual components, and can be applied to other virtual laboratory developments. The virtual laboratory provides a means for students to gain hands-on experience with electronic instruments and improve their understanding of theoretical concepts.
