The purpose of this article is to present and discuss two recommended sequences of learning the areas of polygons, starting from the area of a rectangle. Exploring the algebraic derivations of the two sequences reveals that both are valid teaching progressions for introducing the area formula for various polygons. Further, it is suggested that…

How are teachers who identify as "digital literacy trailblazers' exploring and experimenting with digital tools in their English classrooms? Based on a study of English teaching with digital tools, this paper draws on the case of one secondary school teacher and her year 9 class as they read Diary of a Young Girl (Anne Frank) and engage with…

An algorithm is presented for factorising a quadratic expression to facilitate instruction and learning. It appeals to elementary geometry which may provide better insights to some students or teachers. There have been many methods for factorising a quadratic expression described in school text books. However, students often seem to struggle with…

In this paper, the authors describe the initial stage of developing a framework designed to support out-of-field, less experiences or isolated mathematics and science teachers to make decisions about the use of resources in their teaching. The process highlighted the complexity and extent of the knowledge on which expert teachers draw in making…

Space-filling curves are related to fractals, in that they have self-similar patterns. Such space-filling curves were originally developed as conceptual mathematical "monsters", counter-examples to Weierstrassian and Reimannian treatments of calculus and continuity. These were curves that were everywhere-connected but…

This article discusses using students' analysis of media coverage of the March 2011 Japanese earthquake, tsunami and nuclear events to develop their knowledge and understanding of geological concepts and related socio-scientific issues. It draws on news reported at that time, identifies themes in those reports, and suggests how this event can be…

Space to Grow is an Australian Research Council Grant that engages high school students in real science and supports their teachers in implementing inquiry-based approaches using astronomy as the focus. Currently, Grade 9-12 students and their science teachers from three educational jurisdictions in one Australian state are acquiring, and making…

Practical work is often considered to be a highlight of science classes for students. However, there are few opportunities for students to engage in an investigation which is situated in a real world problem and students are required to contribute their own ideas to the design and conduct of an experiment. This paper reports on a Scientists in…

This is the first of two papers that draw on a study of the national BHP Billiton Science Awards, a peak competition funded by BHP Billiton and administered by CSIRO. BHP Billiton, CSIRO and ASTA together oversee the strategic direction of the Awards. This paper reports an analysis focussed on the outcomes for students of participation in open…

"Guitar Hero" is a video game where one or more players use a specially made game-style guitar to play along to popular and well-known songs. Players need to match the correct notes and timings of the sings. An on-screen guide shows players which notes to play, when. There are levels of difficulty in the game, as well as the choices to…

More than any previous generation, today's students need to develop a global perspective and be knowledgeable about other nations in order to play a better role on the global stage. This paper first reviews some earlier and current studies on students' knowledge of the world, mainly conducted in the United States, and then it describes the global…

This article highlights the authors' research, beginning with the development of a language to define and discuss coping, then the development of two coping programs for adolescent-aged youth, and concluding with evaluations of these programs for youth who are low in resources. (Contains 2 tables.)

Describes the integration of content from science, mathematics, and technology learning areas as well-grounded in the philosophy of middle schooling. Points out the absence of recent research on how students learn science and mathematics concepts in integrated settings. Analyses 9th grade students' learning experiences in a technology project of…

This book emphasizes the process of learning in immersion programs, particularly those related to reading. It explores language learning processes and experiences among French late immersion grade 9 students and Australian teachers completing a university-based Chinese immersion graduate diploma. Using students from each group as key informants,…

Describes a study of Australian independent schools that assessed the use of laptop computers in science classrooms in grades eight and nine. Highlights include students' perceptions of teachers' interpersonal behavior; associations between teacher-student interpersonal behavior and students' attitudes to science and their enquiry skill…
