GEL1503 SUMMARY STUDY NOTES GEL1503 - Environmental Geology The planet Earth, which we study in Geology today, came into existence in some manner together with other planets and stars and has developed into its current composition and structure. However, the limitations of science have thus far only allowed us to form hypotheses (conjectures) about the originating processes of the universe. • After reading chapter 1 in UE-6, which is about the origin of our system of planets, you shou...

The case-based learning (CBL) approach is an andragogical (adult teaching/ learning) approach that examines contextualised questions which are based upon clinical or non-clinical ‘real-life’ problems. In CBL, a structured concept is presented in a standardised case format where each student exposed to the case has a clear understanding of the issues to be solved (Lunney 2008). CBL uses a guided inquiry method and provides more structure during small-group sessions. Hayward and Cai...
