Abstract:
The process of student evaluation is based on a
procedure where we assume that the student belongs just to one
set in a completely specified way, for example the set of
excellent students, or the set of regular students. In this paper
we use fuzzy sets concepts just to propose a different procedure
which can be useful to manage the student’s performance in a
variation of a computerized adaptive testing administration
process. This can be made by assuming that, for a given student,
a membership function is assigned. In this system, fuzzy
controller is used for student’s ability evaluation based on CAT
(Computer Adaptive Testing ) system. There are three types of
questions forms: basic, intermediate and advanced. A student
can choose one of these types of question and answer these
questions. Inputs of membership functions (time and marks) are
given by the student’s answer sheet and using the time interval.
Inputs of membership functions (time and marks) are given by
the student’s answer sheet and using the time interval. There are
three types of student’s ability (poor, regular and brilliant) as
an output. Center of Gravity (COG) defuzzification method is
used in this system. This system is implemented by using C#
programming language.
