Scientific Mathematics takes place over 2 hours on Thursday afternoons. The format for this, specified in the module specification, is one hour lecture followed by one hour problems class.
I cannot imagine anyone watching me write on the board for a whole hour and still taking anything in. I cannot imagine students, having done this, sticking around for a second hour of doing problems.
I talked with a couple of maths lecturers about this and it was recommended to me that I talk for 5-10 minutes, maybe as many as 20 minutes, then give them 10 minutes of exercises to do, then repeat for the 2 hours. This seemed like a much better plan.
