Mechani-Kits Senior Design Project, Jake Utley, Sophie Carson, Vincent Seguin

Mechanical Engineering

Studies suggest that when designed and executed well, hands-on activities can enhance student understanding of key mechanics concepts. Current products are expensive and typically not designed to meet a variety of learning objectives. Through the Mechanics of Inclusion and Inclusivity in Mechanics grant, the Cal Poly Physics and Engineering Departments are seeking to incorporate new hands-on activities into their courses. Our team has designed three inexpensive ”MechaniKits” to be used in physics, statics and dynamics courses [1]. This Final Design Review outlines our findings, objectives, and final designs for this project. It also explains our manufacturing and design verification plans. …

Work-In-Progress: Implementing Sophomore Cornerstone Courses In Electrical And Computer Engineering, Branimir Pejcinovic, Melinda Holtzman, Phillip Wong

Electrical and Computer Engineering Faculty Publications and Presentations

Many engineering programs have significant project-based courses in the freshman and senior years. The project component in our freshman year-long sequence evolves from minimally structured projects, like designing and building Rube-Goldberg contraptions, to more complex microcontroller-based projects where formal tools for teamwork and project management are introduced. However, we do not yet enforce strict adherence to procedures and processes in the freshman year. This is unlike the senior capstone, where the expectation is that students will not only be familiar with these methods but will use them effectively throughout their projects. This presents an obvious problem: what happens in the …

Evolution Of Computational Thinking Contextualized In A Teacher-Student Collaborative Learning Environment., John Arthur Underwood

LSU Doctoral Dissertations

The discussion of Computational Thinking as a pedagogical concept is now essential as it has found itself integrated into the core science disciplines with its inclusion in all of the Next Generation Science Standards (NGSS, 2018). The need for a practical and functional definition for teacher practitioners is a driving point for many recent research endeavors. Across the United States school systems are currently seeking new methods for expanding their students’ ability to analytically think and to employee real-world problem-solving strategies (Hopson, Simms, and Knezek, 2001). The need for STEM trained individuals crosses both the vocational certified and college degreed …

Understanding Early Childhood Engineering Interest Development As A Family-Level Systems Phenomenon: Findings From The Head Start On Engineering Project, Scott Pattison, Gina Svarovsky, Smirla Ramos-MontañEz, Ivel Gontan, Shannon Weiss, VeróNika NúÑEz, Pam Corrie, Cynthia Smith, Marcie Benne

Journal of Pre-College Engineering Education Research (J-PEER)

There is growing recognition that interest is critical for engaging and supporting learners from diverse communities in engineering and other science, technology, engineering, and mathematics (STEM) topics. Although interest research has historically focused on older children, studies demonstrate that preschool-age and younger children also develop persistent, individualized interests in different objects, activities, and topics and that these early interests have important implications for ongoing learning and development. Unfortunately, there is relatively little research on engineering learning in early childhood and almost no work specific to the concept of interest. To begin to address this need, we conducted in-depth case study …

Design Of A Shallow-Aero Ebb And Flow Hydroponics System And Associated Educational Module For Tri Cycle Farms, Julie Halveland

Biological and Agricultural Engineering Undergraduate Honors Theses

Tri Cycle Farms, whose main mission is to reduce food insecurity in their community, is a non- profit urban farm in Fayetteville, Arkansas. The “Tri” in their name refers to the three parts of their foundation: giving a third of their yield to volunteers, giving a third to local food pantries, and selling a third to sustain the farm and demonstrate the economy of local food production. They want to expand on the third part and have a vision of building a hydroponic greenhouse with the intention that it will create more crops to sell and give, as well as …

Accelerating Reinforcement Learning With Prioritized Experience Replay For Maze Game, Chaoshun Hu, Mehesh Kuklani, Paul Panek

SMU Data Science Review

In this paper we implemented two ways of improving the performance of reinforcement learning algorithms. We proposed a new equation to prioritize transition samples to improve model accuracy, and by deploying a generalized solver of randomly-generated two-dimensional mazes on a distributed computing platform, our dual-network model is available to others for further research and development. Reinforcement Learning is concerned with identifying the optimal sequence of actions for an agent to take in order to reach an objective to achieve the highest score in the future. Complex situations can lead to computational challenges in terms of both finding the best answer …

Seventh-Grade Students' Use Of Heat Transfer Conceptions During An Engineering Design-Based Stem Integration Curriculum, Emilie A. Siverling, Tamara J. Moore

Integrated Engineering Department Publications

As the integration of STEM becomes increasingly important in pre-college education, it is important to study models of STEM integration. One model, engineering design-based STEM integration, has shown promising results in terms of student science content learning. This study’s purpose was to explore one student team’s use of heat transfer conceptions as they participated in an engineering design-based STEM integration curriculum. A case study research design, along with procedures from qualitative content analysis, were used to identify scientific and alternative conceptions that the seventh-grade students communicated during the unit. The main result is that the students spoke and wrote about …

Concrete Beam Design: Pouring The Foundation To Engineering In T&E Classrooms, Andrew J. Hughes, Chris Merrill

Educational Leadership & Technology Faculty Publications

Ask a middle or high school student if they could design a concrete beam that weighs only 20 pounds and is 36” long but must hold 600 pounds without failing. What is the student likely to say? What if the student was told that, with some optimized decision making based on relatively straightforward mathematics, their beam could hold 2400 pounds or more? The focus of this article is not on concrete beam design, it is rather an introduction to engineering principles in beam design using a lab activity. The concepts and skills learned in this article will lead students into …

Analyzing Concrete Beam Design: Verifying Predictions In T&Ee Classrooms, Andrew J. Hughes, Chris Merrill

Educational Leadership & Technology Faculty Publications

Design is often accepted as a fundamental aspect of engineering (Dym, et al., 2005). The design process is frequently portrayed as a set of steps. However, the design process is more complex than just a set of steps in a relatively fixed process. The complex nature of design, design thinking, questioning, and decision-making is exactly what technology and engineering classrooms are well suited to address. When addressing the question—“Why is technology and engineering education (T&EE) so important?”—the authors believe T&EE’s importance relates to our discipline’s ability to solve complex problems by balancing theory and practice in engaging hands-on learning scenarios …
