Graphic display of classroom interaction
Wragg tried to make the Flanders system more suitable for analysing the foreign language classroom simply by doubling the number of categories, resulting in a twenty-category system: 'Categories 11 to 20 are the same as Flanders 1 to 10 but are used when interactions occur in the foreign language' (Wragg, 1974:100).
The flint system (moskowitz,1971)
The acronym 'FLint' stands for 'Foreign Language Interaction' analysis and was devised by Gertrude Moskowitz, as an aid to foreign language teachers for self-observation. It is a more complex system than FIAC, and Moskowitz recommends that teachers should master FIAC first (Moskowitz,1971:214)
