Course description 4

• Problems with learning statistics– Convoluted mathematical thinking

• Much of the theory produced by mathematicians using their own format of expression

• The need for mathematical “proof”

– Specialised terminology– Linking abstract mathematical concepts with concrete

and practical research problems

• To learn statistics– Repeated exposure to the same contents

• Understand the theories and be familiar with the jargons• Do many exercises• Discuss problems with tutors

Page 12: Mater Research Support Centre Statistics Course 2006 Introductory Talk

Course description 5• Multi-dimensional teaching : all components important

– Web page contents– Email correspondence with tutors– FAQ– Lecture discussion sessions

• Just attending the lectures is insufficient– Without previous reading, the lectures will be confusing– No idea what is already learnt, and what is new– No idea what questions to ask– Even if lecture can be followed, little is retained because it is too abstract

• Recommended– Do as much self study as possible, using the resource materials– Contact tutors if help needed– Consult the FAQ– Go to the lectures prepared, ask questions– After the lecture, go over the materials again– Contact tutors again if needed
