A Model of Formative Assessment in Science Education

This paper reports on the findings of a 2-year research project into the process of formative assessment in the science classrooms of 10 teachers. Formative assessment is defined as the process used by teachers and students to recognise and respond to student learning in order to enhance that learning, during the learning. The findings indicate that the teachers used two kinds of formative assessment, planned and interactive. Planned formative assessment involved the teachers eliciting and interpreting assessment information and then taking action. It tended to be carried out with the whole class. Interactive formative assessment involved the teachers in noticing, recognising and responding, and tended to be carried out with some individual students or small groups. This paper discusses these two types of formative assessment, how they are related, how they are integral to teaching and learning processes, and how they are dependent on teachers' pedagogical knowledge.
