The social construction of a Teacher Support Team: an experience of university lecturers’ professional development in STEM

Abstract

This paper focuses on understanding and exploring how a group of university engineering and science tutor educators learn and assimilate new conceptions about their role in the face of the forces of globalisation that are transforming the system of higher education. This research paper adopts the notion of the Teacher Support Team (TST) as developed by Daniels and grounded in Vygotsky’s sociocultural account of the social formation of mind. These structures of meaning provide insight into the role played by the context, the interactions, the needs and the demands of actual activities, agreements and learning processes that this group of STEM lecturers undertook as they sought to transform their usual teaching methods that were focused on individual and isolated work in order to create more innovative practices and impact on their students’ performance. The analysis of this experience, which was based on the epistemological principles of the sociocultural approach, focused on the educational model that emerges from needs that are perceived and shared through the group’s interactions, as well as the transitions that such a team undergoes in its actions and decisions.     

Measuring Student Perceptions of Blackboard Using the Technology Acceptance Model

Web Enhanced Instruction (WEI) is not intended to replace the traditional classroom setting, but rather to supplement the traditional lecture with course content that can be accessed from campus or the Internet. WEI has the potential to extend the boundaries of traditional classrooms by providing new opportunities for communication and interaction between students and the instructor. While the potential benefits of augmenting the traditional class with WEI have been recognized and discussed, what has remained largely unknown are student reactions to WEI as an addition to the traditional lecture. The Technology Acceptance Model (TAM) has been widely used in the Information Systems research to gather user reactions to information systems. The TAM examines users' perceptions of Usage, Usefulness, and Ease of Use. This research applied the TAM to the academic setting to measure student reactions to Blackboard, the WEI tool used in this study. Using several multivariate methods, results suggest that students (n = 692) found that the Blackboard elements which are associated with Course Content (Course Documents, Lectures, Student Tools, Announcements, and Quizzes) are used more often and are seen as more useful than those items that provide Course Support and communication (Discussion Board, External Web Sites, Faculty Information, and E‐Mail).

线性SISO TS模糊系统万能逼近的一种新的充分条件

借助于最优逼近理论, 证明了线性SISO TS模糊系统可以逼近任意一个多项式, 然后以Weierstrass逼近定理为桥梁, 证明了该模糊系统可以以任意精度逼近一个任意的连续函数, 从而得到了该模糊系统万能逼近性的一个新的充分条件. 并在证明过程中, 得到了要达到所要求的逼近精度所需的输入模糊集的下确界. 然后从理论上将所得的结果与现有文献中的结果进行了比较, 证明了该结果所需的输入模糊集的数目要少得多, 从而可以简化模糊系统的设计. 最后举例证明了该结论的有效性.     

How and why the CAUT became involved in collective bargaining

Despite a persistent belief to the contrary, most Canadian universities prior to the 1960s did not operate collegially. They were run autocratically. Collective bargaining arose as a means of ensuring true collegiality through negotiations between equals, legally entrenching due process and academic freedom, and providing a clearer and stronger mechanism for dealing with salaries and benefits. This was a revolution from below in the governance of universities. Although the sixties are widely regarded as the age of student revolt, in Canada it was the faculty, not the students, who secured a dramatic change in the power structure of the university through collective bargaining.     

Teaching Plan‐Do‐Study‐Act (PDSA) in a Supply Chain Context: A Paper Football In‐Class Activity

We develop a single‐class period learning game for the Plan‐Do‐Study‐Act (PDSA) improvement cycle. The experiential activity walks teams through the PDSA problem‐solving process as they create paper American footballs and improve their performance using each step of the cycle. The game is one of the first to focus on PDSA. Key benefits include increased student attention, engagement, and learning. Empirical tests show that participant pre‐ and post‐test scores regarding their understanding of each phase of PDSA improved 21.2% after completing the game. Additionally, the treatment group performed 16.6% higher than the control group. In participant perception questions, 85% of participants felt the game was more effective than lecture or reading, 93% felt the game was fun, 95% felt the game improved their understanding of PDSA, and 98% felt the game was engaging.
