A search on the Internet for resources for teaching statistics yields multiple sites with data sets, projects, worksheets, applets, and software. Often these are made available without information on how they might benefit learning. This paper addresses potential benefits from resources that target trend and variability relationships in bivariate data. The paper is in five parts. The first is the introduction. In the second, trend and variability are defined. In the third, the author quotes research on the characteristics of data that influence students' discernment of trend and variability, and identifies data sets that have particular characteristics and that can be freely downloaded from the web. The fourth part of the paper is a short review of free text-based resources. The final part is a review of spreadsheet programs and Java applets. The paper is relevant to teaching and learning in secondary schools. (Contains 5 tables and 5 figures.)

School principals have difficulty embracing the competing demands of school restructuring. These demands include being accountable for the outcomes of other decision-making groups within, or external to, the school community; having strong views while making decisions collaboratively; and using group processes without wasting the time, commitment, motivation and goodwill of those involved. The three sets of tensions were named the accountability, autonomy, and efficiency dilemmas, respectively. This paper outlines the development of an instrument to determine the saliency of particular domains of decision making in which these dilemmas are experienced by school principals. The instrument was trialled in Australia and New Zealand using Rasch analysis to check the fit of items. The instrument is currently being applied in The Netherlands, Australia and Taiwan, with other countries to follow. (Contains 7 figures and 3 tables.)

Presents a student mathematics project aimed at developing students' skills with computer spreadsheets and using the Internet to give students an appreciation of the many ways that mathematics can describe common everyday items--in this case the bicycle--and make them aware of their own role in learning.

Editorial. Introduces a series of articles about mathematics, including the use of calculators with computer-algebra systems.

This paper presents an examination of ICT resources created by pre-service science teachers. After a great deal of modelling, use and discussion regarding ICT materials, twenty-seven pre-service science teachers created ICT resources for use in lower secondary science classrooms. These resources were submitted in a number of formats and were designed with a variety of beliefs about instruction and interaction. The study highlights two important points. The process was focused around the need to create higher order thinking tasks based on a taxonomy of learning. Pre-service teachers have a tendency to make minimal use of multimedia audio and video material in their resources. [ABSTRACT FROM AUTHOR]
