A simple microscopy assay to teach the processes of phagocytosis and exocytosis

Phagocytosis and exocytosis are two cellular processes involving membrane dynamics. While it is easy to understand the purpose of these processes, it can be extremely difficult for students to comprehend the actual mechanisms. As membrane dynamics play a significant role in many cellular processes ranging from cell signaling to cell division to organelle renewal and maintenance, we felt that we needed to do a better job of teaching these types of processes. Thus, we developed a classroom-based protocol to simultaneously study phagocytosis and exocytosis in Tetrahymena pyriformis. In this paper, we present our results demonstrating that our undergraduate classroom experiment delivers results comparable with those acquired in a professional research laboratory. In addition, students performing the experiment do learn the mechanisms of phagocytosis and exocytosis. Finally, we demonstrate a mathematical exercise to help the students apply their data to the cell. Ultimately, this assay sets the stage for future inquiry-based experiments, in which the students develop their own experimental questions and delve deeper into the mechanisms of phagocytosis and exocytosis.

Television Teaching: Parody,The Simpsons,and Media Literacy Education

This paper examines televisual parody as a media literacy educator, and the potential of parody to channel the powers of comedy and entertainment in order to “teach” the techniques and rhetoric of televisual texts and genres. It focuses on the case of the hugely successful and popular animated parodic sitcom, The Simpsons, and its playful attack on advertising and promotional culture. Currently in its 16th season, The Simpsons broadcasts to approximately 60 million viewers in 70 countries weekly, offering a playful critique of television from within the television frame.

Engaging MSW Students in Faculty Research: Students’ Perspectives of Involvement in a Program Evaluation

Engaging social work students in research is challenging, in part, because of the way research is taught in the classroom and the need for learners to effectively develop connections between the “abstract world” of research concepts with the “real world” of professional experiences. This article describes the experiences of graduate social work students involved in a process and outcome evaluation of a community-based program. Analysis of student learning outcomes and the team-based model used to engage students in the evaluation are provided to put forth a paradigm of teaching social work research through direct, supervised, and collaborative engagement.     

Changes in Examination Performance in English Secondary Schools over the Course of a Decade: Searching for Patterns and Trends Over Time

The article explores changes in the examination performance of a random sample of 500 English secondary schools between 1992 and 2001. Using econometric methods, it concludes that: there is an overall deterministic trend in school performance but it is not stable, making prediction accuracy poor; the aggregate trend does not explain improvement over time at school level, where there is very considerable variation in improvement paths; there is a degree of persistence with respect to changes in performance at school level but it is short-lived; whilst there is evidence of a general upward trend across schools, there is a large amount of year-to-year variation and little evidence of sustained improvement at school level; and the model applied has little ability to forecast the direction of change for particular schools in the following year(s).
