This paper presents research on the effects of a cognitive acceleration intervention in science lessons on low socioeconomic students in a government high school in regional Western Australia. "Thinking Science Australia" is a programme currently being implemented in Australian junior high school classes. The research was conducted for…

This paper presents a case study of a teaching intervention designed to enrich Year 2 students' theory of biology through the introduction of causal mechanisms of inheritance such as the gene and DNA. The researchers worked collaboratively with the classroom teacher to design the intervention based on the students' prior knowledge of living things…
