Examining the effect of multiple writing tasks on Year 10 biology students’ understandings of cell and molecular biology concepts

This paper reports on a study that examined the cumulative effects on students’ learning of science, and perceptions of the role of writing in learning, when the students engaged in multiple writing tasks with planning strategy support. The study was conducted with Year 10 biology students who completed two consecutive units on Cells and Molecular Biology. A mixed method study was implemented using a pre-/post-test design with a focus on student performance on higher order conceptual questions, and semi-structured interviews with treatment students after the completion of each unit of study. Results from the quantitative component indicated that multiple, non-conventional writing had a significant benefit in helping students learn Molecular Biology. The results for the Cell unit were not so conclusive suggesting the strategies are most useful for novel content. The interviews with students demonstrated that they understood and engaged successfully with both the conceptual and linguistic demands of the tasks. These findings, taken as a whole, confirm that multiple writing tasks can support effective student learning, provided various pedagogical conditions are met.
