title: Exploring Fijian high school students’ conceptions of averages

authors: Sharma, Sashi

subjects: education

abstract: This paper focuses on part of a much larger study that explored form five (14 to 16 year-old) students’ ideas in statistics. A range of ideas was explored, including the students’ ideas about measures of centre and graphical representations. Students’ ideas about measures of centre were analysed and categories of responses identified. While students could compute mean and median, they were less competent with tasks that involved constructing meanings for averages. This could be due to an emphasis in the classroom on developing procedural knowledge or to linguistic and contextual problems. Some students used strategies based on prior school and everyday experiences. The paper concludes by suggesting some implications for mathematics education.

title: The effect of grammar teaching on writing development

authors: Andrews, Richard

subjects: education

abstract: This article reports on the results of two international systematic research reviews which focus on different aspects of teaching grammar to improve the quality and accuracy of 5-16-year-olds' writing in English. The results show that there is little evidence to indicate that the teaching of formal grammar is effective; and that teaching sentence-combining has a more positive effect. In both cases, however, despite over a hundred years of research and debate on the topic, there is insufficient quality of research to prove the case with either approach. More research is needed, as well as a review of policy and practice in England with regard to the teaching of sentence structure in writing.

title: An investigation by LA-ICP-MS of possum tooth enamel as a model for identifying childhood geographical locations of historical and archaeological human from New Zealand

authors: Cameron, Kristie Elizabeth

subjects: LA -IC P-MS

abstract: LA -IC P-MS (laser ablation-inductively coupled plasma-mass spectrometry) has been used to analyse enamel from the teeth of brushtail possum (Trichosurus vulpecula) in order to model a method for identifying the childhood geographical origin of human remains within New Zealand. The model application of the method is promising for establishing locations of historical and archaeological human remains, including preserved heads, upoko tuhi.
