This paper provides a reports on the application of a fuzzy set decision
making approach in evaluating the characteristics of teaching among
lecturers at a university. The approach outlined here is based on the fuzzy
sets theory with the objectives of normalising the data on teaching
characteristics evaluation into fuzzy numbers and to rank the degree of
contribution in five teaching characteristics from two faculties. The study
employed a questionnaire which consisted of five major characteristics of
teaching and learning sampled from one hundred and twenty three lecturers
from a public university in the east coast of the Peninsular Malaysia. The
five teaching characteristics were Planning and preparation of teaching,
Lecture room/lab teaching, Preparation of teaching resources, Course
evaluation system, and Relationship between student-lecturer. The
questionnaires were distributed to students by the general staff at the end of
every semester for three consecutive semesters. Two definitions of
contributions in teaching as linguistic labels were defined to represent the
five characteristics prior normalization to fuzzy numbers. In the process of
decision making, specified goals had to be attained and specified constraints
had to be fulfilled. Decision making by intersection of fuzzy goals and
constraints was used to analyze the data. The study found that various
degrees of membership were recorded for every teaching characteristics
ranging from 0.28 to 0.73. The application of fuzzy sets theory in the
decision making environment positively leads to useful numerical hierarchy
which provides an effective indicator to the decision makers.
