3D-Printed Lab Equipment for Vibrations and Controls

Facilitators: Dr. Ayse Tekese and Dr. Tris Utschig, Kennesaw State University

This workshop will provide an opportunity for participants to use (1) low-cost, portable, 3D-Printed Laboratory Equipment (3D-PLE) and (2) virtual simulations developed in MATLAB Simscape. These tools are designed to demonstrate fundamental concepts taught in undergraduate-level mechanical vibrations and control theory courses and their associated laboratories. The tools support all types of learners by incorporating multiple modes of learning. The tools presented in the workshop are unique in that they can be used across many contexts, from dedicated laboratories to quick in-class demonstrations to at-home use for homework or projects. Each tool (in both the 3D-PLE and simulation formats) is paired with a POGIL-like (Process-Oriented Guided Inquiry Learning) learning activity designed to facilitate student learning by activating prior knowledge, priming students with key information and theoretical models needed for the learning the concept, engaging with the tool itself, and responding to critical thinking questions. Some applications for incorporating these tools in dynamics, vibrations, and control theory courses include but are not limited to, system identification using methods such as logarithmic decrement, validation of theoretical models, parametric analysis for different system components such as vibrations caused by rotating unbalanced mass, designing a vibration isolator to dampen the vibrations acting on a primary mass, and calculation of the modes of multi-degree of freedom systems. Participants will use three different devices and learn to run their paired virtual simulations during the workshop. They will also have the opportunity to complete parts of the learning activities that students experience when learning with these tools.

An Impactful Use of Multiple-Choice Questions for Assessment

Facilitator: Dr. Autar Kaw, University of South Florida

Multiple-Choice Questions (MCQs) are a standard assessment tool in engineering education, each type having distinct advantages and drawbacks. This discussion delves into these aspects, aiming to improve the overall effectiveness of MCQs. The workshop objectives are to equip participants with the ability to 1) conduct and score an in-class MCQ examination, 2) construct MCQ examinations strategically, and 3) use statistics to improve the MCQ examination. Whether conducted in a physical classroom using paper or LMS, MCQ exams require specific resources. A demonstration will showcase the essentials for in-class paper-based MCQ exams, then explore a free, open-source solution for scoring – requiring no programming skills – as an alternative to paid programs like Scantron and Zipgrade. The workshop will then discuss a blueprint for writing MCQs to reduce threats to the validity of an MCQ exam, ensure questions will be asked at distinct levels of learning, and create a balanced examination. Best practices will be emphasized while identifying flaws through examples. Participants will engage in a think-pair-share activity to craft MCQ items tailored to their courses. Analyzing student responses becomes crucial in improving an MCQ examination. A user-friendly, open-source solution will be presented, offering graphical and text outputs of key statistical variables such as difficulty index, discrimination index, distractor analysis, and item characteristic curves. Guiding decisions on keeping, revising, or removing them from the test will be discussed. This comprehensive approach aims to empower participants with the skills and knowledge needed to enhance the reliability and validity of MCQ examinations.

Integrating Entrepreneurially Minded Learning into Your Course

Facilitator: Dr. Simon Ghanat, The Citadel

Entrepreneurial Mindset (EM) is characterized by the Kern Entrepreneurial Engineering Network’s (KEEN) 3Cs: Curiosity, Connections, and Creating Value. The Entrepreneurial Mindset is a set of attitudes, dispositions, habits, and behaviors that are used in critical thinking, problem-solving, innovation, and value creation. The training workshop can be applied to any course. By the end of the workshop, attendees should be able to:

  • Identify the need for EML
  • Explain the 3Cs of EML
  • Describe the backward design process
  • Apply backward course design

Implementing Hands-on Labs for Remote Learners Taking Introductory Engineering Courses

Facilitators: Dr. Matthew J.Traum and Alex D. Lacerna, The University of Florida

This workshop’s objective is to simulate for attendees the student experience using a GatorKits Lab™ educational lab kit. The workshop demonstrates how instructors can deliver pragmatic laboratory experiences to remote learners taking online undergraduate engineering courses. It illuminates the institutional and pedagogical advantages of this approach. Attendees who complete the workshop will be prepared to implement remotely accessible introductory engineering laboratories in courses at their home institutions.
