Argumentation is a core practice of science and has recently been advocated as an essential goal of science education. Our research focuses on the discourse in urban high school science classrooms in which the teachers used the same global climate change curriculum. We analyzed transcripts from three teachers' classrooms examining both the…

Since their first use students, parents and others have assumed that grades are reliable measures of student achievement. "In short, most Americans have a basic trust…

Principles of networked learning, constructivism, and connectivism inform the design of a test case through which secondary students construct personal learning environments for the purpose of independent inquiry. Emerging web applications and open educational resources are integrated to support a "Networked Student Model" that promotes…

Constructivist pedagogies are generally not considered to support the teaching of mathematics for externally assessed examination-based courses. In large part, teachers have believed that such approaches are inefficient in covering a set syllabus. This article summarises the author's learning journey in Year 12 mathematics in 2004 where attempts…

Informed by an amalgam of notions drawn from constructivist, socio-cultural, metacognitive and self-regulation theory, the discourse created to describe assessment to enhance learning has gone through a number of iterations or discursive shifts. As a result, the current discourse is both ambitious and complex with the roles and responsibilities…
