Challenging Old Teaching Methods
At the end of 2012, 60% of students at a university in England failed their statistics course. During the previous five years, all the teachers had taught the statistics course in exactly the same way, and each year between 80% to 85% of students passed the course. Some new teachers, who started teaching in 2012, concluded that the lack of new teaching methods was the main cause of the problem in 2012. Teachers with more experience did not agree and challenged the new teachers' conclusion.
