The document discusses predicting student performance in final examinations. It examines using linear regression and multilayer perceptron algorithms on attributes of student postings in discussion forums and attendance scores. The case study involved 50 students, and the multilayer perceptron model produced slightly more accurate results based on correlation coefficients and error rates. Specifically, the multilayer perceptron model had a higher correlation coefficient of 0.84 compared to 0.82 for linear regression, and lower mean absolute and root mean squared errors.
3. INTRODUCTION
Research involve educational data is highly increased. The
main objective of Educational data Mining includes
performance prediction, student modelling, domain
modelling, analysis and visualization of student data etc.
Research on students’ performance prediction have been
studied from various attributes in students’ environment like:
students’ behavior,
demographics,
students’ information,
psychological and
socio-economic.
4. INTRODUCTION
Each attributes consist of several elements :-
The students’ demographics include place of residence, hobbies, family
size, employment and others.
The students’ information similar to admission or enrolment data,
includes names, age, gender, etc.
Psychological attributes concern with abilities, attitides, behavior .
Socio-economic describe about the socio-economic background of the
student and family .
5. Different Studies
To predict student recruitment
Number of posts in discussion are significantly impact
students’ performance.
Another one that predicted students’ tardiness to see who the
slow learners.
The factor of ATND(Attendance in the class) was the most
influencing attribute, which affected the performance of
students.
6. Case Study
The main objective of the study was to find the best
classification of algorithm between linear regression and
multilayer perceptron.
The dataset collected from 50 undergraduate students
majoring in Information System Management.
It was processed in WEKA, an open machine learning software
used for analyzing and predicting students’ performance.
7. ATTRIBUTES USED IN PREDICTING
STUDENTS’ FINAL EXAMINATION
ATTRIBUTES DESCRIPTION
POSTING Total students posting in discussion forum
ATTENDANCE Attendance score
9. Linear Regression
This method allows us to summarize and study relationships
between two continuous variables:
One variable, denoted x, is regarded as the predictor, explanatory, or
independent variable.
Other variable, denoted y, is regarded as the response, outcome, or
dependent variable.
In this experiment:-
Dependent variable is final grade effect on one or more
independent variables (posting and attendance).
10. Multilayer Perceptron
Multi Layer perceptron (MLP) is a feedforward neural network
with one or more layers between input and output layer.
Feedforward means that data flows in one direction from
input to output layer (forward).
Each node will have a weight, which then, multiply the input
node that generate the output prediction.

Linear Regression 0.82 12.63 16.14
Multilayer Perceptron 0.84 11.85 15.83
Correlation coefficient describes the degree of connectedness between
the actual value and the value predicted.
Mean absolute error (MAE) is defined as quantity used to measure
how close predictions or forecasts are to the eventual outcomes.
Root mean square error (RMSE) is defined as frequently used measure
of the differences between values predicted by a model or an estimator
and the values actual observed.
12. RESULTS
The result showed that multilayer perceptron give good
prediction results than linear regression.
This study will contribute to the students to improve their
learning experiences through online discussion forums.
Lecturers can improve the ability to manage their class
through an online discussion forum as this forum can give a
great influence to the success of student learning.
