In this study, we illustrated an application of the confirmatory mixture IRT model for multidimensional tests. We aimed to examine the differences in student performance by domains with a confirmatory mixture IRT modeling approach. A three-dimensional and three-class model was analyzed by assuming content domains as dimensions and cognitive…

Both school and district administrators use the results of standardized, large-scale tests to inform decisions about the need for, or success of, educational programs and interventions. However, test results at the school level are subject to random fluctuations due to changes in cohort, test items, and other factors outside of the school's…

In recent years, the use of personal electronic devices has become widespread in Canadian society, and many Canadian schools are adopting "bring your own device" policies. This exploratory research investigates the technological practices of middle years students with mathematics learning disabilities who use personal electronic devices…

This paper aims to critique and develop neo-Vygotskian work in mathematics education from (i) within the Vygotskian and activity theoretic tradition, and where necessary from (ii) a Bourdieusian perspective. First, I critique Roth and Radford's (2011) version of Cultural-historical Activity Theory, suggesting that a classroom episode presented as…

This case study of a grade six classroom literacy curriculum in Ontario, Canada was designed to produce new knowledge of how curricula can promote multimodal literacy learning opportunities for students. With a focus on constraints and enablers, the study found few opportunities for multimodal literacy learning due to standardised assessments, an…

This study reports on the professional learning of two teachers of science who were learning to engage their grade four students in meaningful, hands-on learning. Teachers' learning took place in the context of a 10-month university-based action research program designed to help improve the practice of science, technology, engineering and…

This study investigated the prospective association between moral disengagement and bystander behaviors in bullying situations, including both defending and passive bystanding. A diverse sample of Canadian school children (N = 130; 68 boys and 62 girls; mean age = 11.36 years) participated in a three-wave longitudinal study over a 4-month period.…

Explicit pedagogy that focuses on visual design and composition principles can affect students' responses to and understanding, interpretation and analysis of images, as well as the creation of their own visual representations. This article considers the why, the what, and the how of teaching various visual elements of art and design to students…

Background: Although making explicit links between procedures and concepts during instruction in mathematics is important, it is still unclear the precise moments during instruction when such links are best made. Aims: The objective was to test the effectiveness of a 3-week classroom intervention on the fractions knowledge of grade 5/6 students.…

Using data from the international Teacher Education and Development Study: Learning to Teach Mathematics (TEDS-M), the measurement equivalence of teachers' beliefs across countries is investigated for the case of "mathematics-as-a fixed-ability". Measurement equivalence is a crucial topic in all international large-scale assessments and…
