4.1. Findings from textbook observation
The table below shows the percentages of occurrence of
various NPs found in the textbook. It is notable that Form 10
(N1 + (N2) + (…) + N) occupy the biggest proportion (42%),
followed by Form 2 (ADJ + N) (21%). In contrast, the other
forms are much less common in the textbook with much
lower percentages, ranging from 2% to 7%.
