   Purpose As the field of Computer Science (CS) continues to diversify and expand, the need for undergraduates to explore career possibilities and develop personalized study paths has never been greater. This reality presents a challenge for CS departments. How do the students striving to become competent professionals in an ever-changing field of study? How do they do this efficiently and effectively? This study addresses such questions by introducing RadGrad, an online application combining features of social networks, degree planners and serious games. Design/methodology/approach RadGrad application is designed to promote participation in extracurricular activities, value real-world experience and provide guidance for students planning their degrees. What follows is an exploration of how the application was designed, along with an analysis of how students used it in its first year. Findings Findings suggest RadGrad helped students to participate in relevant community activities and take an active role in planning their degrees. Originality/value The paper describes the features of the application, introducing how the concept of Innovation, Competence and Experience (ICE) scores – rather than a GPAs – were used to motivate undergraduates to participate in extracurricular activities. Initial results suggest RadGrad and the concept ICE scores can be applied to any field where students are encouraged to gain real-world experience as part of their degree program. Lessons learned and future directions are discussed.

2. Teaching Fluid Mechanics and Heat Transfer in Hands-on and Virtual Settings with Low Cost Desktop Learning Modules

   Reynolds, Olivia; Curtis, Heidi; Gartner, Jacqueline; Dahlke, Katelyn; Adesope, Olusola; Dutta, Prashanta (January 2022, IJEE International Journal of Engineering Education)

   Although there is extensive literature documenting hands-on learning experiences in engineering classrooms, there is a lack of consensus regarding how student learning during these activities compares to learning during online video demonstrations. Further, little work has been done to directly compare student learning for similarly-designed hands-on learning experiences focused on different engineering subjects. As the use of hands-on activities in engineering continues to grow, understanding how to optimize student learning during these activities is critical. To address this, we collected conceptual assessment data from 763 students at 15 four-year institutions. Students completed activities with one of two highly visual low-cost desktop learning modules (LCDLMs), one focused on fluid mechanics and the other on heat transfer principles, using two different implementation formats: either hands-on or video demonstration. Conceptual assessment results showed that assessment scores significantly increased after all LCDLM activities and that gains were statistically similar for hands-on and video demonstrations, suggesting both implementation formats support an impactful student learning experience. However, a significant difference was observed in effectiveness based on the type of LCDLM used. Score increases of 31.2% and 24% were recorded on our post-activity assessment for hands-on and virtual implementations of the fluid mechanics LCDLM compared to pre-activity assessment scores, respectively, while significantly smaller 8.2% and 9.2% increases were observed for hands-on and virtual implementations of the heat transfer LCDLM. In this paper, we consider existing literature to ascertain the reasons for similar effectiveness of hands-on and video demonstrations and for the differing effectiveness of the fluid mechanics and heat transfer LCDLMs. We discuss the practical implications of our findings with respect to designing hands-on or video demonstration activities.

3. What Makes an Inquisitive Engineer? An Exploration of Question-Asking, Self-Efficacy, and Outcome Expectations among Engineering Students.

   Pink, S.; Rieken, B.; Bjorklund, T.; Sheppard, S. (January 2017, Proceedings of the American Society for Engineering Education Annual Conference, June 25-28. Columbus, OH.)

   In order be successful, engineers must ask their clients, coworkers, and bosses questions. Asking questions can improve work quality and make the asker appear smarter. However, people often hesitate to ask questions for fear of seeming incompetent or inferior. This study investigates: what characteristics and experiences are connected to engineering students’ perceptions of asking questions? We analyzed data from a survey of over a thousand engineering undergraduates across a nationally representative sample of 27 U.S. engineering schools. We focused on three dependent variables: question-asking self-efficacy (how confident students are in their ability to ask a lot of questions), social outcome expectations around asking questions (whether students believe if they ask a lot of questions, they will earn the respect of their colleagues), and career outcome expectations (whether they believe asking a lot of questions will hurt their chances for getting ahead at work). We were surprised to find that question-asking self-efficacy or outcome expectations did not significantly vary by gender, under-represented minority status, and school size. However, students with high question-asking self-efficacy and outcome expectations were more likely to have engaged in four extracurricular experiences: participating in an internship or co-op, conducting research with a faculty member, participating in a student group, and holding a leadership role in an organization or student group. The number of different types of these extracurricular activities a student engaged in correlated with question-asking self-efficacy and positive outcome expectations around asking questions. The results illustrate the relationship between extracurricular activities and students’ self-efficacy and behavior outcome expectations. The college experience is more than just formal academic classes. Students learn from experiences that occur after class or during the summer, and ideally these experiences complement class-derived skills and confidence in asking questions.

4. Teaching Fluid Mechanics and Heat Transfer in Hands-on and Virtual Settings with Low Cost Desktop Learning Modules

   Reynolds, O. M. (October 2022, International journal of engineering education)

   Although there is extensive literature documenting hands-on learning experiences in engineering classrooms, there is a lack of consensus regarding how student learning during these activities compares to learning during online video demonstrations. Further, little work has been done to directly compare student learning for similarly-designed hands-on learning experiences focused on different engineering subjects. As the use of hands-on activities in engineering continues to grow and expand to non-traditional virtual applications, understanding how to optimize student learning during these activities is critical. To address this, we collected conceptual assessment data from 763 students at 15 four-year institutions. The students completed activities with one of two highly visual low-cost desktop learning modules (LCDLMs), one focused on fluid mechanics and the other on heat transfer principles, using two different implementation formats: either hands-on or video demonstration. To examine the effect of implementation format and of the learning tool used, learning gains on conceptual assessments were compared for virtual and hands-on implementations of fluid mechanics and heat transfer LCDLMs. Results showed that learning gains were positive and similar for hands-on and video demonstrations for both modules assessed, suggesting both implementation formats support an impactful student learning experience. However, a significant difference was observed in effectiveness based on the type of LCDLM used. Score increases of 31.2% and 24% were recorded on our post-activity assessment for hands-on and virtual implementations of the fluid mechanics LCDLM compared to pre-activity assessment scores, respectively, while smaller 8.2% and 9.2% increases were observed for hands-on and virtual implementations of the heat transfer LCDLM.

5. Multidimensional Aspects of Vector Mechanics Education Using Augmented Reality

   https://doi.org/10.18260/1-2--47785  

   Giancaspro, James; Arboleda, Diana; Chin, Seulki; Yang, Liping; Secada, Walter (June 2024, ASEE Conferences)

   The objective of this paper is to provide a holistic summary of ongoing research related to the development, implementation, assessment, and continuous refinement of an augmented reality (AR) app known as Vectors in Space. This Unity-based app was created by the authors and provides a self-guided learning experience for students to learn about fundamental vector concepts routinely encountered in undergraduate physics and engineering mechanics courses. Vectors are a fundamental tool in mechanics courses as they allow for the precise and comprehensive description of physical phenomena such as forces, moments, and motion. In early engineering coursework, students often perceive vectors as an abstract mathematical concept that requires spatial visualization skills in three dimensions (3D). The app aims to allow students to build these tacit skills while simultaneously allowing them to learn fundamental vector concepts that will be necessary in subsequent coursework. Three self-paced, guided learning activities systematically address concepts that include: (a) Cartesian components of vectors, (b) unit vectors and directional angles, (c) addition, (d) subtraction, (e) cross product using the right-hand rule, (f) angle between vectors using the dot product, and (g) vector projections using the dot product. The authors first discuss the app's scaffolding approach with special attention given to the incorporation of Mayer's principles of multimedia learning as well as the use of animations. The authors' approach to develop the associated statics learning activities, practical aspects of implementation, and lessons learned are shared. The effectiveness of the activities is assessed by applying analysis of covariance (ANCOVA) to pre- and post-activity assessment scores for control and treatment groups. Though the sample sizes are relatively small (less than 50 students), the results demonstrate that AR had a positive impact on student learning of the dot product and its applications. Larger sample sizes and refinements to the test instruments will be necessary in the future to draw robust conclusions regarding the other vector topics and operations. Qualitative feedback from student focus groups conducted with undergraduate engineering students identified the app's strengths as well as potential areas of improvement.
