Description
Despite the prevalence of teams in complex sociotechnical systems, current approaches to understanding workload tend to focus on the individual operator. However, research suggests that team workload has emergent properties and is not necessarily equivalent to the aggregate of individual workload. Assessment of communications provides a means of examining aspects of team workload in highly interdependent teams. This thesis set out to explore how communications are associated with team workload and performance under high task demand in all-human and human–autonomy teams in a command and control task. A social network analysis approach was used to analyze the communications of 30 different teams, each with three members operating in a command and control task environment of over a series of five missions. Teams were assigned to conditions differentiated by their composition with either a naïve participant, a trained confederate, or a synthetic agent in the pilot role. Social network analysis measures of centralization and intensity were used to assess differences in communications between team types and under different levels of demand, and relationships between communication measures, performance, and workload distributions were also examined. Results indicated that indegree centralization was greater in the all-human control teams than in the other team types, but degree centrality standard deviation and intensity were greatest in teams with a highly trained experimenter pilot. In all three team types, the intensity of communications and degree centrality standard deviation appeared to decrease during the high demand mission, but indegree and outdegree centralization did not. Higher communication intensity was associated with more efficient target processing and more successful target photos per mission, but a clear relationship between measures of performance and decentralization of communications was not found.

Description
Teamwork and project management (TPM) tools are important components of sustainability science curricula designed using problem- and project-base learning (PPBL). Tools are additional materials, beyond lectures, readings, and assignments, that structure and facilitate students' learning; they can enhance student teams' ability to complete projects and achieve learning outcomes and, if instructors can find appropriate existing tools, can reduce time needed for class design and preparation. This research uses a case study approach to evaluate the effectiveness of five TPM tools in two Arizona State University (ASU) sustainability classes: an introductory (100-level) and a capstone (400-level) class. Data was collected from student evaluations and instructor observations in both classes during Spring 2013 and qualitatively analyzed to identify patterns in tool use and effectiveness. Results suggest how instructors might improve tool effectiveness in other sustainability classes. Work plans and meeting agendas were the most effective TPM tools in the 100-level class, while work plans and codes of collaboration were most effective at the 400 level. Common factors in tool effectiveness include active use and integration of tools into class activities. Suggestions for improving tool effectiveness at both levels include introducing tools earlier in the course, incorporating tools into activities, and helping students link a tool's value to sustainability problem-solving competence. Polling students on prior use and incorporating tool use into project assignments may increase 100 level tool effectiveness; and at the 400 level, improvements may be achieved by introducing tools earlier and coaching students to select, find, and develop relevant tools.

Description
Experiential learning has gained the attention of higher education institutions, specifically business schools, as a way to bring the business world into the classroom. It has become a fundamental methodology for designing business schools' curricula that promotes 21st-century skills like problem-solving, creativity, and teamwork. This study evaluates an experiential learning-based undergraduate business program and its signature entrepreneurship course. The goal is to understand how the entrepreneurship course and its experiential learning component, design sprint, influence first-year students' entrepreneurial mindset, creative self-efficacy and teamwork self-efficacy. Additionally, this study aims to understand the perceptions of first-year undergraduate students of their experiential activities and how they make sense of these experiences.
This action research study draws from theories of learning and psychology, such as Experiential Learning Theory (ELT) by Kolb (1984, 2015); mindset theory by Dweck et al. (1995) and Dweck (2006); self-efficacy by Bandura (1977, 1997); and figured worlds by Holland et al. (1998). These theories support the research questions by emphasizing the collaborative nature of learning, how beliefs about learning, intelligence, and capabilities influence an individual's behavior, and how the environment shapes an individual's interpretation of the world.
This mixed-methods action research study combines quantitative data in the form of a pre and post-intervention survey. The qualitative data was gathered from interviews that focused on understanding the experiences of participating students and their perceptions of their learning after the intervention workshop. Additionally, qualitative data included a feedback survey after the workshop to learn students' perceptions of the intervention activities.
The results of this study suggest that experiential learning activities support students' growth of their creative skills and help them view entrepreneurship from a user-centered perspective. Additionally, results suggested that short-term experiential projects tend to inhibit students from growing in their teamwork skills as they focus all their attention to their project. Lastly, results suggest experiential learning programs can become a space for collaboration, skill development, and motivated students. However, it can also lead to students feeling frustrated and alienated due to the professional codes permeating experiential settings. The study concludes with several implications for practitioners.
