Hi all! I'm due to start my masters dissertation in September and considering researching mathematics textbooks in some way - not exactly sure of the direction yet. As a secondary maths teacher myself I've noticed a decline in the use of textbooks in the classroom - despite the huge amount of money we spend on new textbooks every time there's a change in specification etc so thought it'd be useful to look at the effectiveness of them and whether the money would be better spent elsewhere. At this preliminary stage I'd really appreciate people's responses to the following questions to help me clarify the focus of my assignment. Does your department primarily use a set of textbooks for the pupils to work from? What are the limitations of the text books that you use? What would your ideal textbook include? Many thanks in advance for taking the time to respond! All responses no matter how short greatly appreciated.
