Alan Johnson, Education Secretary, recently announced plans to scrap maths coursework, which looks good for Home Educators as coursework was difficult to manage without outside help. On the downside, he also said that all coursework in other subjects will be supervised, which will effectively put the mockers on HEors doing any GCSEs other than maths. International Baccalaureates may look like the better option.
As to the muddle - we thought coursework was originally introduced at least in part so that pupils could improve upon their research skills and learn to draw upon any source of good information, much as they would in the real world. Preventing learners from using these resources completely puts pay to that.
