Process gain and process loss: comparing interpersonal processes and performance of culturally diverse and non-diverse teams across time

Members of 82 student groups involved in a Team Learning instructional format were surveyed with the Group Style Instrument (GSI) to examine the possible dimensions of team oriented behaviors and individualistically oriented behaviors. Exploratory factor models and confirmatory factor models were compared to find the best factor structure fit. The GSI was found to have dimensions that were team and individualistically oriented. From a second sample data was collected across four months on the group process and group performance of culturally non-diverse and culturally diverse groups. Data were evaluated in two significant ways. First, the team orientation and individual orientation dimensions were used to define interpersonal processing. Second, the team process dimensions were used to define interpersonal processing. Second, the team process dimensions were examined further to evaluate their relation to group performance. Early on the diverse teams showed less team orientation and more individual orientation than non-diverse teams, but through frequent feedback on task and interpersonal processing, the diverse teams caught up by the third time period. By the end, diverse teams maintained high team orientation but also allowed a reasonable extent of individual orientation. The diverse teams were beginning to utilize diversity to their advantage. Team and Individualistic orientations showed significant relations to team performance across time. Suggestions are given for future research.     

Evaluation of Interactive Media in Science Education

An evaluation of an interactive media-based science education project is reported. One of the unique features of the evaluation is the application of a general program evaluation which stresses the assessment of contextual/environmental factors. The rationale is that without adequate facilitation and support from the context, large scale projects would have limited impact on education reform. The model was applied to a major, National Science Foundation funded, science teacher education project at Vanderbilt University. The findings revealed that a number of factors must come together for project success. They are: an environment conducive to innovation and development; strong administrative interest and commitment to further the cause of the project; faculty interest and commitment to be actively involved in the project and to integrate project ideas into their own practices. In addition, strong technical support is vital for research and developments efforts in technology-based science education projects.     

Self assembled monolayers

In recent years, a number of systems have been shown to spontaneously assemble on appropriate solid surfaces to form films with thicknesses of molecular dimensions. The special techniques needed to prepare, characterise and study such monolayers are described. The potential applications of these systems as catalysts, sensors, electrooptic and other materials are summarized.     

Uncertainty in the real world

In this part of the article we have identified fuzzy uncertainty as being distinct from probabilistic uncertainty. We have understood the notion of a fuzzy set, and seen important operations that can be performed on such sets. Lastly, a geometrical interpretation of the fuzzy set and its attendant operations were discussed. In Part 2, we will develop a framework for reasoning based on fuzzy sets, and review a simple application.     

Advancing Culturally Relevant Pedagogy in a Secondary Methods Course

Given changes in the U.S. school-age population, it is crucial that colleges of education prepare teacher candidates to work effectively with students from diverse backgrounds. Because diversity constitutes such a small portion of the curriculum in many teacher education programs, it is crucial that teacher educators find creative ways to incorporate diversity into the courses they teach. In this article a teacher educator at a predominantly White institution in the American Southeast describes how she introduces culturally relevant pedagogy and connects it to the content, activities, and assessments included in the remainder of a course.     

Livelihoods and informal trade at the Bangladesh border

Abstract

Cross‐border informal trade is one of the most important issues between India and Bangladesh. It takes place between people who live a short distance apart, but who find themselves separated by an international boundary. The people of international border areas believe that cross‐border informal trade is a process to maintain a sustainable livelihood because it provides a livelihood to the unemployed. This research has analysed the nature and impact of informal border trade between India and Bangladesh. It has highlighted the sources of security and insecurity through the process of informal border trade. It also analyses the different socio‐economic conditions of informal border trade in border trade prone areas. This research argues that although informal border trade is considered illegal, it is necessary for the maintenance of the livelihood for the poor in the bordering areas. The state failures in fulfilling the needs of the poor force them to involve themselves in informal border trade.     

An analytical solution to applied mathematics-related Love’s equation using the Boubaker polynomials expansion scheme

In this paper, we present a method for the numerical solution of Love's equation in a particular physical system. The resolution protocol is based on the Boubaker Polynomials Expansion Scheme (BPES), followed by array analyses. The obtained results are compared with some recently published ones. The accuracy and the asymptotic behaviors of the solutions are discussed.
