Still busy with marking. New topic: Should scientists be concerned with moral issues? Should be lots of scope for an interesting discussion, particularly as we consider the duties, obligations and responsibilities of the scientist to self and to society, and how the scientist might cope with conflicts between his/her professional conduct and his/her personal ethics especially in the more controversial fields of study.
It's interesting to note, however, that our students still place more emphasis on memorizing and reproducing their lecture notes as verbatim as possible rather than actually considering their material and discussing what they understand with respect to the question. Regardless of our push towards thinking skills, our students still rely on memory as the key indicator of their intelligence, and assume that we will reward them for it.
About half a year left to patch up the damage. It's a living.
