Statistics has been a content domain in the mathematics curriculum for decades. However, statistics is a distinct discipline from mathematics and there are important differences in how one should teach the two disciplines. In this article, the authors consider how these differences can inform an adaptation to the 5 Practices for Orchestrating…

The aim of the study was investigation of the effect of twice application of the Group Investigation method at different intervals on improvement of the students' academic achievement and science process skills in teaching the science lesson. Method of the study was a quasi-experimental design. The study used Solomon Four-group Experimental Design…

Density has been reported as one of the most difficult concepts for secondary school students (e.g. Smith et al. 1997). Discussion about the difficulties of learning this concept has been largely focused on the complexity of the concept itself or student misconceptions. Few, if any, have investigated how the concept of density was constituted in…

"If someone were traveling to our area for the first time during this time of year, what would you tell them to bring to wear? Why?" This question was used to engage students in a guided-inquiry unit about how climate differs from weather. In this lesson, students explored local and national data sets to give "travelers" advice…

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…

The messages students receive through popular media such as movies, television, the internet, and music videos have a powerful influence and can shape their thinking. A national survey of media use by 8- to 18-year-olds found the average adolescent spends over seven and a half hours daily with entertainment media (KFF 2010). Rather than viewing…

There is, no doubt, untapped potential in using technological tools to enhance the understanding of science concepts. This study examines the potential by observing 7th and 8th grade middle school students' (n=23) use of portable data collection devices in a nine-week elective class, "Exploring Technologies". Students' use of the data collection…

Many children struggle to learn to read, and these difficulties can persist well into adulthood. To address this problem, researchers have investigated the processes that underlie reading. An informative body of work has thus identified basic skills (e.g., decoding, vocabulary knowledge) as necessary for successful reading. Researchers also have…

This is a record of the proceedings of the 30th annual conference of the Mathematics Education Research Group of Australasia (MERGA). The theme of the conference is "Mathematics: Essential research, essential practice." The theme draws attention to the importance of developing and maintaining links between research and practice and…
