Concern about a lack of Curriculum for Excellence guidance aimed at science teachers has led to a new document, largely produced by teachers themselves.
Science: Interpreting Excellence was put together by the Association for Science Education Scotland. It was completed by an editorial team of three, and a writing team of 19, a year after the initial concept.
Vice-chairman Stuart Farmer said it was an excellent example of teachers sharing their expertise, in a relatively short timescale, to produce a 106-page document that would "fill the vacuum left by our national support agencies".
An introduction stresses that the guidance is not prescriptive, but should be seen instead as "stimulus material".
"We wanted to avoid reducing science education to a sequence of activities defined only by the CfE experiences and outcomes," it states.
Oil giant BP contributed funding towards the guidance.
The document costs pound;10 for members and pound;17 for non-members.
