 Diagrams and charts 
Diagrams and charts serve two main purposes: to help the reader visualizer relati-Ohs- ---
given in a text; to supplement information given in a text. It is up to you to decide
which diagram or chart will best aid your understanding of the lecture. A number of
charts abound such as pie- chart, histogram, tree diagram, etc.
Elements of note taking and making
Experts are of the opinion that there are four elements that are vital to note taking
and making, these are originality: This involves using your own words and sentences,
in other words your own diction and language. This will help you master what you
have learnt better. Conciseness: Be brief and straight to the point, make sure that your
note contains only the salient points; it is not worth the effort if unnecessary
explanations and digressions a~e found in your note. Clarity: Let your note be very
clear to the reader, without this, the aim of note taking is defeated, and Completeness:
A note is said to be complete if it incorporates the various sections of a lecture
(Aborisade, 2005, Akioja-Vincent Lucky, 2007 & Asiegbu, 2011).
