„Different teaching styles and practices can be especially beneficial for some students but less so for others. It is, therefore, difficult to pinpoint teaching practices that are 'superior' to others. For instance, there is evidence that cognitive activation strategies may be more beneficial for socio-economically advantaged students and teacher-centred instruction for disadvantaged, at-risk students.“
