Hand, Brian; Yang, Olivia Eun-mi; Bruxvoort, Crystal – International Journal of Science and Mathematics Education, 2007
This study researched the use of writing-to-learn strategies within a high-school (Year 11) chemistry classroom. The writing task itself asked the students to write a business letter to a younger audience of middle-school (Year 7) students. A mixed-method design was used for the study, incorporating pre/post- testing with semi-structured…
