In this paper, we examine the use of an ordinary differential equation in modelling the SARS outbreak in Singapore. The model provides an excellent example of using mathematics in a real life situation. The mathematical concepts involved are accessible to students with A level Mathematics backgrounds. Data for the SARS epidemic in Singapore are…

Hierarchical agglomerative cluster analysis (HACA) may yield different solutions under permutations of the input order of the data. This instability is caused by ties, either in the initial proximity matrix or arising during agglomeration. The authors recommend to repeat the analysis on a large number of random permutations of the rows and columns…

The following laboratory exercise was designed to aid student understanding of the differences between subjective and objective measurements. Students assess the color and texture of different varieties of potato chip (crisps) by means of an intensity rating scale and a rank test and objectively with a colorimeter and texture analyzer. For data…

This article uses a case study of 2001 town and city data that we analyzed for "Boston Magazine". We use this case study to demonstrate the challenges of creating a valid ranking structure. The data consist of three composite indices for 147 individual townships in the Boston metropolitan area representing measures of public safety; the…

In attempting to provide empirical qualitative data analysis, the researcher has to work within many constraints. There are ethical issues that need to be considered and evaluated in the managing of data, especially one that is naturally occurring. One of the more popular methods of "capturing" this data is through audio recording and to be able…

In this article, the author emphasizes decision making rather than mere remembering as a tool for teaching social studies. Decision making should be emphasized at two levels: at the level of deciding what a group of descriptive data means, how these data may be summarized or generalized, what principles they suggest; and also at the level of…

This article investigates children's evaluation/selection of ideas in writing-related tasks. The critical dimension being considered was to what extent the communicative goal that defines argumentation establishes basic criteria with which children decide whether to include counterargument in a text. Data analysis focused on participants'…

This paper discusses the importance of evaluating state assessment data in order to improve learning. The Glens Falls City School District in upstate New York began in-depth analyses of state assessment data and Terra Nova scores over the last three years. Teachers and administrators work together in a new way to highlight strengths and weaknesses…

This manual describes the methods, procedures, techniques, and activities that were used to produce the Academic Library Survey of 2004 (ALS:2004). This manual is designed to provide guidance and documentation for users of the ALS data. Included in the manual are the following: (1) an overview of the study and its predecessor studies; (2) an…

This document provides an overview of key finance data terms and is designed to accompany the "Financial Accounting for Local and State School Systems: 2003 Edition" by identifying common reporting requirements and defining frequently used indicators and calculations using data elements from accounting and other data systems. It also…

Conducting scientifically rigorous evaluations of character education interventions is complex. This evaluation guide is presented as a resource primarily for project directors who are federal grantees embarking on an evaluation of a character education intervention, although it contains useful information that can benefit other education…

This publication features a series of reports on how selected colleges and universities foster and assess student learning in twelve liberal education outcome areas, including writing, quantitative literacy, critical thinking, ethics, intercultural knowledge, and information literacy. Moving from goals to experiences, assessments, and improvements…

A qualitative study of group therapy for aphasia was undertaken in order to discover interaction patterns and discourse management strategies that help define "social" or "conversation" group therapy for aphasia. Specifically, an analysis of the discourse of clients and therapists was conducted to identify patterns across therapists and settings.…

Current research and theory suggest that the healthy path of autonomy development involves gradual negotiation of adolescents' independence "within" a context of continued family connection. This theory-generating study examined the role that adolescents' participation in youth programs plays in these adolescent-parent negotiations. Qualitative…
