I have been swamped with work for the past week or so. That's why you haven't seen too much updating on this blog. Besides, it's not as if they found the Higgs already, so the news on the physics front have been relatively quiet.
Still, I was going to read this paper and post a comment on it. But I've been sitting on it for the past week and haven't gotten past by the introduction paragraph. so I thought I might as well post it on here and let you people have a go at it.
Abstract: During a one-semester-long research project with high school students,
we deployed and gauged efficiency of two different reform teaching
methods: reading, presenting, and questioning (RPQ) and experimenting
and discussion (ED). In this paper we report on changes in students’
attitudes and beliefs about physics and learning physics. We used the
Colorado Learning Attitudes about Science Survey (CLASS v3) to assess
the relative effectiveness of the two methods. The data show that both
methods improved student attitudes and beliefs but to different extents.
The RPQ group (91 students) achieved an overall improvement of +5.8% in attitudes and beliefs, while the ED group (85 students) attained an improvement of +25.6%.
These results suggest that both methods may have a substantial
potential for improving students’ attitudes and beliefs about physics
and physics learning, with the ED method being more promising than the
Would be interesting to see the nature of the differences in the CLASS survey.
