Masters courses are usually taught courses, and the MPhil and PhD courses are usually higher degrees by research.

Forensic and criminology students can teach science (Biology/Chemistry) at secondary level.
Both Forensic and Criminology and single subject Criminology students can get onto primary teaching courses, or citizenship and RE courses. The other way to get into teaching is via an enhancement course in subjects that are difficult to fill, such as mathematics and modern languages. See University of Hull as an example of this: http://www2.hull.ac.uk/ifl/ces/courses/pgce/subject-knowledge-enhancement.aspx.
You also can also go study a PGCE in further or adult education. This is usually referred to as a PGCE in Post-Compulsory education.
