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.     

Analyzing time‐critical team motor skill performance: A case study

The ability to improve team motor skill performance is predicated on the corresponding ability to accurately identify areas for improvement. Unfortunately, in many time‐critical, rapid‐paced environments, accurately identifying areas for improvement is often problematic. The technique described in this case study seeks to overcome these difficulties in a systematic manner by employing a video‐recorded, mapping‐and‐measurement‐based approach that can discern details normally missed by human observation.

Continuing the tradition… advancing the boundaries

This study investigated the influence that social and emotional support have on attributional confidence in the brother‐brother relationship. Two‐hundred thirteen males reported on the relationship with their brother. Social support dimensions of relational support, interpersonal depth, relational conflict and emotional support were examined as a function of attributional confidence. Results indicated positive relationships between social support dimensions of relational support and interpersonal depth with attributional confidence. Relational conflict was negatively related to attributional confidence. No significant relationship between emotional support and attributional confidence was observed.

‘We're Going to Make You Popular': Popular Collections in the Modern Academic Law Library

One way to promote the relevancy of an academic law library is to create a special collection that generates interest in the patron base; a popular collection is a viable way of reinventing a law library's image in the hearts and minds of the law school community. Popular collections have been championed by general academic librarians because they promote reading and literacy, the use of the library as a place, and such collections represent the shift toward a user focused library model. Using data collected from interviews and analysis of collection development policies this article presents models of popular collections currently in use at academic law libraries, as well as considerations for the creation of such collections.     

Teaching thinking: the case for principles

Abstract

This paper reviews the situation with regard to the teaching of thinking skills as part of the taught curriculum. The case is made for direct teaching of cognitive skills both to meet the particular learning difficulties of children with special educational needs and also to enhance the learning and thinking of all children. The dangers of ‘recipe’ approaches to teaching this aspect of the curriculum are discussed and a ‘principles’ approach is advocated. Some principles are then described which may be used to underpin the designing of problem‐solving activities, through which thinking skills can be taught across the curriculum.
