Since science should be seen as a fully practical subject with the students on their feet doing things for themselves, and this encouraged and implemented throughout compulsory schooling (5 to 16) it follows that there is no place for the writing of copious revision notes during lessons at any level. Sitting in a science laboratory writing neat notes, which then have to be marked, Y7 to Y13, is anathema to good science teaching, I think. I was trained into this thinking in 1966 on the Nuffield schemes, and have soundly criticised any teacher who puts up neat diagrams as a presentation and then gets the students to copy them into their books or folders. Rough note-making during lessons is their own personal responsibility, again Y7 to Y13, during any activity or demonstration. In all of my teaching, the students had a rough exercise book for this, which I would very occasionally look at, or write in during the lesson with the student by my side. Beyond this, they were encouraged to build up a portfolio or folder of their work, to be used for their own revision purposes and the storing of marked assignments and test papers. Sometimes their own rough notes could be cut and pasted into the loose-leaf folder to illustrate what they were recording. I feel some dismay that this thread has appeared in this day and age with the availability of excellent published resources for revision, and the electronic means of communication and recording now available. This idea of rough note-making and then writing up neatly in my own time was developed by myself throughout my secondary schooling, 1953 to 1960, doing the write-up whether or not it was required by the teacher, and then I continued this throughout my university career. I still have all of my notes thus written (and many of the rough notes), keeping them for posterity!
