In Australia, it has been observed that there have been significant declines in the proportion of students studying senior sciences over the last two decades (Commonwealth of Australia 2017 & 2018; Steidtmann et.al, 2023). It has been suggested that one of the causes for this decline could be a link between students' literacy achievement and…

"Blended" and "flipped" pedagogies are becoming more common features of classrooms as the technological revolution continues. While the appropriate use of technology in the learning environment can serve to motivate some students, significant problems surrounding student motivation and engagement remain. As such, the…

This article presents an instructional strategy called Premise-Reasoning-Outcome (PRO) designed to support students in the construction of scientific explanations. Informed by the philosophy of science and linguistic studies of science, the PRO strategy involves identifying three components of a scientific explanation: (i) premise--an accepted…

Engaging middle school students in science continues to be a challenge in Australian schools. One initiative that has been tried in the senior years but is a more recent development in the middle years is the context-based approach. In this ethnographic study, we researched the teaching and learning transactions that occurred in one ninth grade…

An instructional program using four simulation applets was used to facilitate understanding of gas and liquid pressure concepts among twenty-two students in a Year 9 class from an independent secondary school in Singapore. A comparison group consisting of twenty-two students was taught using traditional didactic, chalk-and-talk instruction.…

In this article, we report on a teacher-researcher collaboration that emerged from a large study on literacy strategies for diverse classrooms. Using the example of one Year 9 class of ten English as an Additional Language (EAL) students, we trialled language-focussed materials on the topic of Ecosystems as an alternative or adjunct to the…

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…

This study involved the evaluation of the efficacy of a planned instructional program to facilitate understanding of the macroscopic, submicroscopic and symbolic representational systems when describing and explaining chemical reactions by sixty-five Grade 9 students in a Singapore secondary school. A two-tier multiple-choice diagnostic instrument…

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…

Many students arrive at high school with enthusiasm for learning Science but by Year 9 some students have become disengaged with Science as a subject. In an attempt to find out the reasons for this, thirty-five Year 9 students from five South Australian secondary schools participated in focus group discussions. This research unearthed a number of…
