Aviation gas has an energy density of 33.5 MJ/L whereas liquid hydrogen only has an energy density of 9.3 MJ/L. If ideas are the fuel that drives teachers then too many are running on liquid hydrogen. Teacher practice is based around a number of key ideas and too many smart, dedicated, caring teachers are being given the wrong ones.
A popular one is ‘it’s all about relationships.’ The implications are students will learn best when the teacher knows their background allowing a positive relationship to be formed and thus the teacher will be able to optimise their teaching and behaviour management of said student. Trouble arises because, although there is a kernel of truth in this, it is flawed as a starting point.
To begin, most teachers have between 20-30 students in their class that can only be successfully managed as a group, not as individuals. If the teacher is in a high school, that number increases to between 100-120 students, often seen all in one day. In these circumstances, the best chance of a positive relationship between a teacher and their students depends on the teacher establishing firm control of student behaviour dynamics so that effective teaching and learning can take place. The best teachers are assertively in charge, approachable yes, but able to command student attention and co-operation to foster learning. They are not setting out to befriend students as a strategy.
Knowing more about the background of students – and yes, some have very difficult backgrounds – can cause a teacher to lower expectations. This might involve going easier on them over behaviour issues or work completion, both of which are unhelpful for the student concerned. For example, a student who is weak at maths, needs more practice at maths, not less. A maths teacher knowing a student is weak at maths but doesn’t do homework because his parents fight every night is not helping them by letting them off work.
The principal of the high school I attended as a student insisted that his teachers be firm, fair and friendly – in that order. Being firm, fair and friendly is not the same as being friendly, fair and firm, which is can be the case with more student-centered approaches. The later approach can place the teacher in the position of soliciting the friendship and good-will of students.
