Scholarly reading
The readings below are classified into aspects of a teacher's subject knowledge underpinning successful teaching of acidity. Some are quite challenging to read and understand. However, no one said it was easy to be a good teacher! There is no test to check your own knowledge! You have to make up your own mind if you are ready to try some other reading.
