Set Up

Teaching wireless networking fundamentals is often difficult because many students appear to find the subject technical, and dry when presented in traditional lecture format. To overcome this problem, we provide an opportunity for experiential learning where students can learn wireless networking fundamentals by hands-on practical activities using low-cost Wi-Fi (wireless fidelity) devices such as wireless cards and access points. Students can easily set up and configure networks using wireless cards and access points more effectively. By measuring network performance such as throughput and end-to-end delays, students are able to gain a deeper understanding of wireless networking. The effectiveness of Wi-Fi-based practical activities has been evaluated by students and the teaching team. This chapter reports on the overall effectiveness of teaching and learning of wireless network using radially available low-cost Wi-Fi cards and access points.

The Impact

Abstract Despite the huge efforts to deploy wireless communications technologies in smart manufacturing scenarios, some manufacturing sectors are still slow to massive adoption. This slowness of widespread adoption of wireless technologies in cyber-physical systems (CPSs) is partly due to not fully understanding the detailed impact of wireless deployment on the physical processes especially in the cases that require low latency and high reliability communications. In this article, we introduce an approach to integrate wireless network traffic data and physical processes data to evaluate the impact of wireless communications on the performance of a manufacturing factory work cell. The proposed approach is introduced through the discussion of an engineering use case. A testbed that emulates a robotic manufacturing factory work cell is constructed using two collaborative-grade robot arms, machine emulators, and wireless communication devices. All network traffic data are collected and physical process data, including the robots and machines states and various supervisory control commands, is also collected and synchronized with the network data. The data are then integrated where redundant data are removed and correlated activities are connected in a graph database. A data model is proposed, developed, and elaborated; the database is then populated with events from the testbed, and the resulting graph is presented. Query commands are then presented as a means to examine and analyze network performance and relationships within the components of the network. Moreover, we detail the way by which this approach is used to study the impact of wireless communications on the physical processes and illustrate the impact of various wireless network parameters on the performance of the emulated manufacturing work cell. This approach can be deployed as a building block for various descriptive and predictive wireless analysis tools for CPS.

Education Outreach

Canadian universities are devoting more and more resources to develop K-12 engineering education outreach programs. The School of Engineering at the University of British Columbia’s Okanagan campus offers a variety of outreach and community programs for students of all ages. This paper provides details on the DiscoverE Engineering Summer Program which has been delivered since 2016. The objective of the program is to introduce students general design processes through hands-on civil, electrical, and mechanical engineering projects. The overall goal is to foster a passion in engineering and at the same time attract students who have already had an interest in engineering and are eager to learn more about the discipline. The program is taught by faculty members and exposes students to a variety of hands-on projects in civil, electrical and mechanical engineering. This paper will provide curriculum details for each topic and reflect on the student learning experience based on observations. Future qualitative plans on the measure of the impact of this program qualitatively will be explored.

The Impact

This study explored the technology learning model of the elderly in a senior learning center under the impact of the COVID-19 pandemic. Many senior learning centers were closed during the pandemic, and many of them adopted the mode of online education. However, problems such as decreased motivation and a lack of peer interaction still exist. To solve these problems, this study used the easy-to-implement calligraphy AR approach and E-book approach to conduct a quasi-experiment on the elderly of a calligraphy course offered by a senior learning center. The results show a higher learning motivation among the elderly who use calligraphy AR. The learning effectiveness and technology acceptance of the elderly in the E-book learning group were higher than those in the calligraphy AR group. The elderly mentioned that the E-book learning approach is more user-friendly. In general, in the face of the COVID-19 pandemic affecting the suspension of classes in senior centers, education through the development of technology has stimulated the growth of education in advanced learning centers. Through this kind of scientific and technological learning method, it will bring a whole new experience to the elderly. It can improve the stress relief methods, mental health, and quality of life of the elderly during the COVID-19 emergency shutdown, and provide a novel calligraphy technique learning experience for the elderly. Therefore, we believe that the calligraphy AR learning approach and the calligraphy E-book learning approach are practical and may promote quality of life and mental health of the elderly during the emergency closures due to COVID-19, providing elderly attendees with a novel calligraphy technology learning experience.

The Relationship

Exposing students to hands-on experiments has been a common approach to illustrating complex physical phenomena that have been otherwise modelled solely mathematically. Compressible, isentropic flow in a duct is an example of such a phenomenon, and it is often demonstrated via a de Laval nozzle experiment. We have improved an existing converging/diverging nozzle experiment so that students can modify the location of the normal shock that develops in the diverging portion to better understand the relationship between the shock and the pressure. We have also improved the data acquisition system for this experiment and explained how visualisation of the standing shock is now possible. The results of the updated system demonstrate that the accuracy of the isentropic flow characteristics has not been lost. Through pre- and post-laboratory quizzes, we show the impact on student learning as well.

The Impact

Twitter has gained attention in recent years as a tool to use in higher education to enhance students’ learning, engagement, and reflective writing. This study explored public health students’ perceptions on the usefulness of Twitter as a learning tool, engagement with their peers, staff, and the broader public health community. Participants were Master of Public Health students from a public university based in Sydney, Australia. A mixed methods approach was used combining content analysis of tweets, an online survey and two focus groups. Students were asked to engage with Twitter by reflecting on each week’s teaching content and by liking and replying to their peers’ tweets. Participation and engagement in this task were high initially and declined toward the end of semester. Most student tweets aligned with topics taught during the semester. Survey and focus group data indicated most students had positive views on using Twitter and reported finding engagement with Twitter beneficial in obtaining current information on health promotion news and trends, increasing their professional networks and allowing them to connect with their peers and teaching staff. Results indicate Twitter is a promising interactive approach to enhance public health students’ engagement and overall learning experience, as well as being useful for professional networking. Larger scale empirical studies are needed to investigate the impact of the use of social media platforms such as Twitter to various learning outcomes longitudinally and beyond this course.

Live cases, where students work directly with an outside organization to solve real-world problems, can be an immersive learning experience for marketing students. Current scholarship on live case usage in marketing is limited to small samples from a handful of live case devotees. This article draws from a large, international sample of 169 marketing educators to investigate the perceived educational impacts of live cases on student skill development. Specifically, the paper explores student teamwork, conflict handling, time management, presentation, communication, and critical thinking skills. Additionally, the article explores how student skill development is affected by the amount of course time dedicated to the live case as well as faculty experience with live cases.
