This study examines the development of self-esteem in a sample of 138 Australian adolescents (90 males; 48 females) with cognitive abilities in the lowest 15% (L-CA) and a matched sample of 556 Australian adolescents (312 males; 244 females) with average to high levels of cognitive abilities (A/H-CA). These participants were measured annually…

In this study, we investigated students' thinking about the use of letters in algebra. Responses from over 1,400 Australian secondary school students to a set of three algebra items were analysed to determine the prevalence of the "letter as object" misconception. We estimate that 50% to 80% of Year 7 students bring this misconception to…

Emotional eating, defined as eating in response to affect, may increase during early adolescence, a time of heightened emotionality and increased prevalence of emotional disorders. We investigated change in emotional eating, while also testing the influence of social-emotional risk factors. Study participants (N = 379, mean age [M[subscript age]]…

National standardized assessment programs have increasingly included extended written performances, amplifying the need for reliable, valid, and efficient methods of assessment. This article examines a two-stage method using comparative judgments and calibrated exemplars as a complement and alternative to existing methods of assessing writing.…

Studies, such as Programme for International Student Assessment 2012, indicate that there are gender based differences in measures of mathematics anxiety, self-concept and self-efficacy among students. In this study we explore self-efficacy, self-concept and mathematics anxiety in a sample of Year 7 and 8 South Australian students to examine if…

In this research, we examined how 200 students in seventh grade (around 12 years old) solved simple addition problems. A cluster approach revealed that less than half of the cohort displayed proficiency with simple addition: 35% predominantly used min-counting and were accurate, and 16% frequently made min-counting errors. Students who frequently…

This study explored students' feelings during the Australian National Assessment Program -- Literacy and Numeracy. It features student voice depicted as self-drawn images accompanied by words as they journeyed through four phases of the NAPLAN process: preparation, participation, completion and results. The 34 students in Years 3, 5 and 7 attended…

Many introductions to algebra in high school begin with teaching students to generalise linear numerical patterns. This article argues that this approach needs to be changed so that students encounter variables in the context of modelling visual patterns so that the variables have a meaning. The article presents sample classroom activities,…

This article describes the development and validation of a newly designed instrument for measuring the spatial ability of middle school students (11-13 years old). The design of the Spatial Reasoning Instrument (SRI) is based on three constructs (mental rotation, spatial orientation, and spatial visualization) and is aligned to the type of spatial…

The International Computer and Information Literacy Study (ICILS) is the first international comparative study that examines students' acquisition of computer and information literacy (CIL). The study assessed student CIL achievement in 18 countries and three benchmarking participants through a computer-based assessment administered to students in…

The Australian Curriculum: Mathematics calls for the concurrent development of mathematical skills and mathematical reasoning. What are the big ideas of mathematical reasoning and is it possible to map their learning trajectories? Using rich assessment tasks designed for middle-years students of mathematics, this symposium reports on the…

Sociocultural theory of body dissatisfaction posits that internalization of the media ideal and appearance comparison are predictors of body dissatisfaction, a key risk factor for eating disorders. However, no data exist regarding the longitudinal relationships between these variables. The aim of this study was to explore longitudinal…

This study examined indicators of mental health, as well as strengths and difficulties, as reported by same-age boarding and non-boarding students spanning four time points over a 2-year period as they transitioned from primary to boarding school in Western Australia (i.e., at the end of Grade 7, beginning of Grade 8, end of Grade 8, and end of…

In explaining academic achievement, school climate and social belonging (connectedness, identification) emerge as important variables. However, both constructs are rarely explored in one model. In the current study, a social psychological framework based on the social identity perspective (Turner, Hogg, Oakes, Reicher, & Wetherell, 1987) is…

In this study we investigated how 200 students in seventh grade (mean age = 12.38 years) solved simple addition problems and if the way they performed simple addition was related to their achievement in mathematics. Four performance groups were identified: proficient, almost proficient, inaccurate min counting and accurate min counting. More than…
