ABSTRACT
Fluid Mechanics courses comprise both theoretical and laboratory modules. In developing nations, computer-assisted techniques are not commonly applied in Fluid Mechanics instruction. Forced by the COVID-19 pandemic, South American universities are, however, using them for online teaching. This contribution presents an 8-semester (2016–2019) educational intervention over an undergraduate Fluid Mechanics course. It mainly blends physical (hands-on) and virtual experiments (computer fluid dynamics-based simulations) for the laboratory module, which are complemented by flipped classroom-based prompts for the theoretical module. The intervention follows design-based research as a research method and is guided via conjecture mapping and fidelity of implementation standards. Our results suggest that the intervention improves fluid mechanics laboratory instruction, although improvements depend upon the participation of other educational actors such as teaching assistants and laboratory technicians to some extent. Laboratory report grades (the assessment instrument) follow the Gompertz probability distribution. Following UNESCO standards, a portion of the intervention output is shared as open educational resources. This contribution encourages upscaling the educational intervention through the formation of cooperative clusters to build common-pool Fluid Mechanics resources. Learning scientists have underlined the need to better understand laboratory instruction processes. They have been addressed in very few instances in developing countries. We believe that this study has the potential to provide valuable insights on the matter. © 2022 Wiley Periodicals LLC.
ABSTRACT
Teamwork is an important skill valued by corporate employers across the globe. As such, it is crucial for students to learn teamwork for the purpose of securing a job and performing well in corporate environments. In addition to certain technical skills, essential 21st-century skills include communication, collaboration, critical thinking, and creativity. A well-known learning theory that helps students learn these skills is cooperative learning. Cooperative learning posits that when students collaborate within teams to solve complex problems, their creativity and critical thinking skills are improved as a result. Implementing cooperative learning in the past several months has been challenging due to the COVID-19 pandemic. The sudden shift from face-to-face to online instruction, has left a void for newer pedagogical approaches to teach teamwork. In this full paper, we investigate the impact of cooperative learning during the Spring 2020 semester by studying team retrospectives written by students enrolled in a system analysis and design course. The pedagogical foundation for the system analysis and design course was cooperative learning. The course required students to work in teams to develop a software prototype. The project was divided into four milestones and each team was required to submit a team retrospective detailing overall planning, task allocation, group processes, and strategies for improvement. The first two milestones were completed during face-to-face instruction, while teams met online for the last two milestones due to the shift to online instruction. To investigate team effectiveness, a rubric based on the Goals, Roles, Processes and Interpersonal relations (GRPI) model of team effectiveness was created and team retrospectives were scored using that rubric. We used a mixed-method approach to explore the following research questions: 1) What was the impact on team effectiveness when instruction changed from face-to-face to online due to the COVID-19 pandemic? 2)What strategies were adopted by teams to navigate the sudden change in instruction? To address the first research question, we performed inferential statistics to compare the impact of team effectiveness between face-to-face and online instruction. To address the second research question, we conducted a thematic analysis to understand the qualitative differences of team effectiveness for face-to-face and online instruction. Our results demonstrate a significant increase in teamwork effectiveness for online instruction. In addition, our thematic analysis shows particular strategies adopted by teams that led to improved team effectiveness in the online instruction environment. © American Society for Engineering Education, 2021
