Educational data mining is the process of applying data mining tools and techniques to analyze data at educational
institutions. In this paper, educational data mining was used to predict enrollment of students in Science, Technology, Engineering and
Mathematics (STEM) courses in higher educational institutions. The study examined the extent to which individual, sociodemographic
and school-level contextual factors help in pre-identifying successful and unsuccessful students in enrollment in STEM
disciplines in Higher Education Institutions in Kenya. The Cross Industry Standard Process for Data Mining framework was applied to
a dataset drawn from the first, second and third year undergraduate female students enrolled in STEM disciplines in one University in
Kenya to model student enrollment. Feature selection was used to rank the predictor variables by their importance for further analysis.
Various predictive algorithms were evaluated in predicting enrollment of students in STEM courses. Empirical results showed the
following: (i) the most important factors separating successful from unsuccessful students are: High School final grade, teacher
inspiration, career flexibility, pre-university awareness and mathematics grade. (ii) among classification algorithms for prediction,
decision tree (CART) was the most successful classifier with an overall percentage of correct classification of 85.2%. This paper
showcases the importance of Prediction and Classification based data mining algorithms in the field of education and also presents
some promising future lines.

Educational Data Mining (EDM) is one of the crucial application areas of data mining which helps in predicting educational dropout and hence provides timely help to students. In Indian context, predicting educational dropouts is a major problem. By implementing EDM, we can predict the learning habits of the student. At present EDM has not been introduced at higher education level. Due to this we cannot recognize the genuine problems of students during their education. The objective of this analysis is to find the existing gaps in predicting educational dropout and find the missing attributes if any, which my further contribute for better prediction. After that we try to find the best attributes and DM techniques which are frequently used for dropout prediction. Based on the combination of missing attribute and best attribute of student data thus far, a new algorithm can be tested which may overcome the shortcomings of previous work done.

Higher learning institutions nowadays operate in a more complex and competitive due to a high demand from prospective
students and an emerging increase of universities both public and private. Management of Universities face challenges and concerns of
predicting students’ academic performance in to put mechanisms in place prior enough for their improvement. This research aims at
employing Decision tree and K-means data mining algorithms to model an approach to predict the performance of students in advance
so as to devise mechanisms of alleviating student dropout rates and improve on performance. In Kenya for example, there has been
witnessed an increase student enrolling in universities since the Government started free primary education. Therefore the Government
expects an increased workforce of professionals from these institutions without compromising quality so as to achieve its millennium
development and vision 2030. Backlog of students not finishing their studies in stipulated time due to poor performance is another
issue that can be addressed from the results of this research since predicting student performance in advance will enable University
management to devise ways of assisting weak students and even make more decisions on how to select students for particular courses.
Previous studies have been done Educational Data Mining mostly focusing on factors affecting students’ performance and also used
different algorithms in predicting students’ performance. In all these researches, accuracy of prediction is key and what researchers

Data Mining Techniques for School Failure and Dropout SystemKumar Goud
Abstract: Data mining techniques are applied to predict college failure and bum of the student. This is method uses real data on middle-school students for prediction of failure and drop out. It implements white-box classification strategies, like induction rules and decision trees or call trees. Call tree could be a call support tool that uses tree-like graph or a model of call and their possible consequences. A call tree is a flowchart-like structure in which internal node represents a "test" on an attribute. Attribute is the real information of students that is collected from college in middle or pedagogy, each branch represents the outcome of the test and each leaf node represents a class label. The paths from root to leaf represent classification rules and it consists of three kinds of nodes which incorporates call node, likelihood node and finish node. It is specifically used in call analysis. Using this technique to boost their correctness for predicting which students might fail or dropout (idler) by first, using all the accessible attributes next, choosing the most effective attributes. Attribute choice is done by using WEKA tool.

Clustering Students of Computer in Terms of Level of ProgrammingEditor IJCATR
Educational data mining (EDM) is one of the applications of data mining. In educational data mining, there are two key domains, i.e. student domain and faculty domain. Different type of research work has been done in both domains.
In existing system the faculty performance has calculated on the basis of two parameters i.e. Student feedback and the result of student in that subject. In existing system we define two approaches one is multiple classifier approach and the other is a single classifier approach and comparing them, for relative evaluation of faculty performance using data mining
Techniques. In multiple classifier approach K-nearest neighbor (KNN) is used in first step and Rule based classification is used in the second step of classification while in single classifier approach only KNN is used in both steps of classification.
But in proposed system, I will analyse the faculty performance using 4 parameters i.e., student complaint about faculty, Student review feedback for faculty, students feedback, and students result etc.
For this proposed system I will be going to use opinion mining technique for analyzing performance of faculty and calculating score of each faculty.

Application of Higher Education System for Predicting Student Using Data mini...AM Publications
The aim of research paper is to improve the current trends in the higher education systems to understand
from the outside which factors might create loyal students. The necessity of having loyal students motivates higher
education systems to know them well, one way to do this is by using valid management and processing of the students
database. Data mining methods represent a valid approach for the extraction of precious information from existing
students to manage relations with future students. This may indicate at an early stage which type of students will
potentially be enrolled and what areas to concentrate upon in higher education systems for support. For this purpose
the data mining framework is used for mining related to academic data from enrolled students. The rule generation
process is based on the classification method. The generated rules are studied and evaluated using different
evaluation methods and the main attributes that may affect the student’s loyalty have been highlighted. Software that
facilitates the use of the generated rules is built which allows the higher education systems to predict the student’s
loyalty (numbers of enrolled students) so that they can manage and prepare necessary resources for the new enrolled students.

1. INTRODUCTION
In today‘s scenario, educational institutions are becoming
more competitive because of the number of institutions
growing rapidly. To stay afloat, these institutions are
focusing more on improving various aspects and one
important factor among them is quality learning. Today,
learning has taken various dimensions such as online
learning, virtual learning, socializing etc. For providing
quality education and to face new challenges, the
institutions need to know about their potentials which are
explicitly seen and which are hidden. The truths behind
today‘s educational institutions are a substantial amount of
knowledge is hidden. To be competitive, the institutions
should identify their own potentials hidden and implement a
technique to bring it out.
Data mining, also called Knowledge Discovery in Databases
(KDD), is the field of discovering and extracting hidden and
potentially useful information from large amounts of data.
Data mining is applied in various fields like medical,
marketing, databases, machine learning, artificial
intelligence, customer relations etc., Recently Data mining
is widely used on educational dataset. Educational Data
Mining (EDM) has become a very useful research area [1].
Educational Data Mining refers to techniques, tools, and
research designed for automatically extracting meaning
from large repositories of data generated by or related to
people's learning activities in educational settings. Key uses
of EDM [2] include learning and predicting student
performance in order to recommend improvements to
current educational practice. EDM can be considered as one
of the learning sciences, as well as an area of data mining
[3]. Romero and Ventura [13], did a survey on educational
data mining between 1995 and 2005. They concluded that
educational data mining is a promising area of research and
it has specific requirements not presented in other domains.
Some of the benefits of data mining in an education sector
are identifying students‘ needs and preferences towards
course choices, and selection of specialisation , identifying
students‘ pattern trends, predicting students‘ knowledge,
grades, and final results, supporting automatic exploration
of data, ‗constructing students‘ profiles become easy, and
helping management to understand business [10].
Sir Francis Bacon (1597) commented, ―Knowledge is
power‖ and in today‘s context it may be rephrased as
―Knowledge sharing is power‖. The extracted information
from the data can be transferred as knowledge and can be
stored in decision making for the betterment of the
institution. Institutions of Higher Learning (IHL) are similar
to knowledge businesses, in that both are involved in
knowledge creation, dissemination, and learning[11].
However, people in business world concerned with the
profit they could gain by exploiting knowledge through the
implementation of KMS whereas IHL consider that KMS
could improve the quality of service deliveries and sustained

competitive advantages in the academic world [12].
Different models have been used by these researchers to
describe the factors found to influence student achievement,
course completion rates, and withdrawal, along with the
relationships between variable factors[14].
This paper makes a novel attempt to look into the higher
educational domain of data mining to analyze the students‘
performance. Section 2 gives the overview of data mining
techniques available to extract the hidden information and
attribute selection methods. Section 3 provides the general
account of the data under study and the pre-process stage of
the data. Section 4 analyzes the impact of various indicators
in the performance of students in higher education and
applying various data mining techniques. Conclusion and a
discussion on future work are in the final section.
1.1 Related Work
In [5] authors proved that data mining for small data sets has
a real potential to become a serious part of higher education
teachers‘ knowledge management systems. Also the study
result show that student data, available to higher education
teachers which falls into the category of a small data set
carries enough student-specific characteristics in the sense
of hidden knowledge which can be successfully associated
with student success rates. In [9] authors used various
different feature selection methods and have found out the
influence of features affecting the student performance. The
authors have used a selected number of attributes and have
not taken attributes like attendance, theory, laboratory etc.
The researchers in [6] conducted a study on a data set of size
50 MCA students for mining educational data to analyze
students‘ performance. Decision tree method was used for
classification and to predict the performance of the students.
Different measures that are not taken into consideration
were economic background, technology exposure etc. El-
Halees.A [13] has done a work on mining students data to
analyze learning behavior. The data size considered was
151. The details include personal and academic records of
students. Classification based on Decision tree is done
followed by clustering and outlier analysis. The knowledge
extracted describe the student behaviour. Han and Kamber
[4] depicted the data mining process and the methods to
analyze data from different perspective and the steps to mine
knowledge.

2. DATA MINING TECHNIQUES AND
ATTRIBUTE SELECTION METHODS
Data mining also termed as Knowledge Discovery in
Databases (KDD) refers to extracting or ―mining‖
knowledge from large amount of data [4]. Knowledge
Discovery process involve various steps in extracting
knowledge from data as shown in Fig. 1.
Fig. 1. Steps in the process of Knowledge Discovery
Data cleaning is the process, which is used to remove noise
and inconsistent data. Data Cleaning routines do fill in
missing values, smooth out noise and identify outliers and
correct inconsistencies in the data [4]. Transformation is a
technique which is used to make the data minable. To
discover useful patterns within the data, we apply data
mining methods. The hidden patterns, associations and
anomalies in a dataset that are discovered by some Data
mining techniques, can be used to improve the effectiveness,
efficiency and the speed of the processes [6]. Different
techniques and models are applied like neural networks,
Bayesian networks, rule based systems, regression and
correlation analysis to analyze educational data[3].
Evaluation is used to extract data with interest. Knowledge
Discovery is involved in a multitude of tasks such as
association, clustering, classification, prediction, etc.
Classification and prediction are functions which are used to
create models that are constructed by analyzing data and
then used for assessing other data. Clustering is a way of
identifying similar classes of objects. Association is mainly
used to relate frequent item set among large data sets. Data
mining for small data sets has a real potential to become a
serious part of higher education teachers‘ Knowledge
Management Systems [5]. This study is carried out using a
small dataset with a number of attributes to analyze the
performance of the students. Feature selection has been an
active and fruitful field of research area in pattern
recognition, machine learning, statistics and data mining
communities [15, 16]. Various attribute selection methods
do exists to identify the attributes that make great impact.
Some of the notable methods are chi-square, information
gain, correlation, gain ratio, and regression.
2.1 Chi-square
Chi-square test is a statistical method used to identify degree
of association between variables [7]. The formula for
calculating chi-square ( 2) is:
2 =
(𝑜 − 𝑒)
e
2
That is, chi-square is the sum of the squared difference
between observed (o) and the expected (e) data, divided by
the expected data in all possible categories.

2.2 Information Gain
Information Gain is used to determine the best attribute
among the attributes in a collection of samples S and if there
are ‗m‘ classes. The expected information needed to classify
a given sample is
𝑰 𝒔 𝟏 𝒔 𝟐, … . 𝒔 𝒎 = −
𝒔𝒊
𝒔
𝐥𝐨𝐠 𝟐
𝒔𝒊
𝒔
𝒎
𝒊=𝟏
An attribute ‗A‘ with values {a1,a2,...,av} can be used to
partition S into subsets where Sj contain those samples in S
that have value aj of A. The expected information based on
this partitioning by A is known as the entropy of A.
𝑬 𝑨 =
(𝒔 𝟏𝒋 + ⋯ + 𝒔 𝒎𝒋)
𝒔
𝒗
𝒋=𝟏
𝑰 𝒔 𝟏𝒋, … . 𝒔 𝒎𝒋
The information gain, Gain(A) of an attribute A, in the
sample set S, is given as
𝑮𝒂𝒊𝒏 𝑨 = 𝑰 𝒔 𝟏, 𝒔 𝟐, … . 𝒔 𝒎 − 𝑬(𝑨)
2.3 Gain Ratio
Gain Ratio is also a measure to determine the best attribute.
It can be calculated as
𝑮𝒂𝒊𝒏 𝑹𝒂𝒕𝒊𝒐 𝑨 =
𝑮𝒂𝒊𝒏 𝑨
𝑺𝒑𝒍𝒊𝒕 𝑰𝒏𝒇𝒐𝒓𝒎𝒂𝒕𝒊𝒐𝒏 (𝑨)
where ‗A‘ is an attribute and Split Information(A) be
calculated as
𝑺𝒑𝒍𝒊𝒕 𝑰𝒏𝒇𝒐𝒓𝒎𝒂𝒕𝒊𝒐𝒏 𝑨 = −
𝒔𝒊
𝒔
𝐥𝐨𝐠 𝟐
𝒔𝒊
𝒔
𝒏
𝒊=𝟏
2.4 Linear Regression
Linear Regression involves finding the best line to fit two
variables so that one variable can be used to predict other
and to find a mathematical relationship between them.
𝒀 = + 𝑿
where Y is a response variable and X is a predictor variable
and , are regression coefficients.
2.5 Correlation
Correlation is used to assess the degree of dependency
between any two attributes. The correlation between the
occurrence of A and B can be measured by computing
If value is less than 1, it is negatively correlated and if
greater than 1 it is positively correlated and if 1 then A and
B are independent.
3. METHODOLOGY
The dataset used for this study for performance analysis was
taken from PG Computer Application course offered by an
Arts and Science College between 2007 and 2012. The data
of 165 students were collected. Student personal and
academic details along with their attendance were collected
from the student information system. The collected
information was integrated into a distinct table. Student
dataset contains various attributes like Theory Scores,
Laboratory scores, Medium of study, UG course, Family
Income, Parental Education, First Generation Learner, Stay,
Extracurricular activities etc. Among the 16 different
attributes initially present, some of the relevant attributes
which accounts to 13 was selected from the table for data
mining process. The three irrelevant attributes are age,
gender and community as the attribute values show only less
variation. Feature selection can be useful in reducing the
dimensionality of the data to be processed by the classifier,
reducing execution time and improving predictive accuracy
[8]. Listed below are the 12 attributes that are selected to
act as predictors and the analysis will be carried using these
different attributes. ‗Result‘ is the attribute of the student
dataset which act as the response variable. The Table 1
further shows the categorical values which define the
possible set of values each attribute will take that can be
used to analyze the given data.

The experiment is carried out with the support of SPSS
statistical software. SPSS has all the capabilities for
correlation, regression, classification, data reduction and
clustering. Using the software, the data is cleaned by filling
the missing values. Also, the selected data is transformed
into categorical form if a numerical data exists. The
categorical form is more suitable for applying various
attribute selection techniques. For example, the family
income attribute can be categorized as ‗Average‘, ‗Good‘
and ‗Poor‘ instead of several numerical values. Thus the
experimental data is pre-processed so that it is more suitable
for feature selection with accuracy.
4. RESULTS AND DISCUSSION
Analysis is done to identify the dependency of predictor
variables with that of the response variable. Techniques like
correlation coefficient, chi-square test, information gain,
gain ratio and regression are used. Feature selection is the
process of removing features from the data set that are
irrelevant with respect to the task that is to be performed [9].
Table 2 shows the list of factors which influence the
performance of the student to a great extent in decreasing
order based on various attribute selection methods.

The above figures show the significance of predictor
attribute towards the response variable using various
feature selection techniques. Fig. 2 shows the values
calculated using chi square. Theory marks, Medium of
Study and Previous Course Studied were the top indicators
for performance prediction. Fig. 3 shows the result of using
correlation analysis. Theory marks, UG percentage and
Laboratory score were the top indicators. Fig. 4 shows the
analysis using Information gain. The result identify that
Theory marks, UG percentage and Family Income were the
major influence factors. From Fig.5 it is observed that
Theory marks, UG percentage and Family Income were the
major influence factors using Gain Ratio.
Fig - 6: Regression measure for various Attributes
Fig. 6 shows that Stay, Parent Education, First Generation
Learners were the key influencers using regression. The
influence factors are analyzed by categorizing the result
obtained in Table 2 into 3 groups High, Medium and Low.
‗High‘ is given if the attributes take 1 to 4 place and it is
categorized as ‗Medium‘ if it takes 5 to 8 place else it is
termed as ‗Low‘. Now, add weightage to High, Medium and
Low category..
Weightage =
From Table 3, we infer that the high impact attributes that
contribute for the performance of the students are TY,MS,
PC, UGP, S, ECA and FI (ie) Theory, Medium of Study,
Previous Course studied, UG Percentage, Stay, Extra
Curricular Activities and Family Income. So if we know the
values of the above mentioned high influencing attributes
we can predict student performance.

5. CONCLUSION
This paper deals with the performance analysis of student.
This study paper on performance analysis of student data
help the institution to decide on the factors to concentrate
for the better performance of the academic results of the
students. The 7 attributes are selected from the 16 initial
factors as more influencing for performance. Thus the
hidden knowledge (performance influencing factors) was
identified from a set of student data. The instructors can take
steps to analyze and improve the student performance if they
know the Medium of Study, UG Percentage, Theory marks
obtained, Stay, Extra Curricular Activities and Family
Income and whether the student was good in Previous
Course studied. The study was carried out using only a small
dataset and it can be extended to a large dataset and can use
factors which are not dealt here. Predicting student
performance by applying data mining techniques will be the
future work.
