"It was the funnest week in the whole history of funnest weeks": our case study, the second phase in a three-phase research project, evaluates the successes and limitations of creative teaching and learning during the "The Creative and Effective Curriculum" module for PGCE primary student teachers which includes a one-week placement in school. Student teachers', children's and teachers' perspectives pointed to a range of factors necessary for effective and creative teaching and learning. These included learning which is "fun," achievement through intrinsic motivation, willingness to take risks and learn from mistakes, children's ownership of learning and the teacher's role as facilitator. Our findings enabled us to formulate "phunometre scales" which we suggest can be used to assess both the organisation of learning areas and also planned activities in terms of their capacity for learning which is both challenging and fun.
