Abstract— Educational Data Mining (EDM) is an emerging
trend, concerned with developing methods for exploring the
large data related to educational system. The data is used to
obtain the Implicit and Explicit knowledge distribution.
Educational Data mining methods are generally used to
determine the performance of students, assessment of students
and study students’ behavior etc. In recent years, Educational
data mining has proven to be more successful at many of the
educational statistics problems due to enormous computing
power and data mining algorithms [1]. This research explores
the applications of data mining techniques applied in
educational field.
The work explores SSTS, a new teaching learning process
framework in higher education. The framework contains
students database consists of various relational attributes. By
applying data mining techniques to the database and mined the
effective students’ knowledge distribution clusters using social
network analysis. The analysis found that good student faculty
relation network clusters and average percentile of effective
knowledge distribution by students’ in higher education.

I INTRODUCTION
Educational Data mining (EDM)
EDM develops methods and applies techniques from
statistics, machine learning, and data mining to analyze data
collected during teaching and learning. EDM tests learning
theories and informs educational practice. Learning analytics
applies techniques from information science, sociology,
psychology, statistics, machine learning, and data mining to
analyze data collected during education administration and
services, teaching, and learning. Learning analytics creates
applications that directly influence educational practice
[2][7]. Educational data mining researchers (e.g., Baker

and Yacef 2009) view the following as the goals for their
research: Predicting students’ future learning behavior ,
Discovering or improving domain models that characterize
the content to be learned and optimal instructional sequences,
Studying the effects of different kinds of pedagogical support
that can be provided by learning software, Advancing
scientific knowledge about learning and learners through
building computational models that incorporate models of the
student, the domain, and the software’s pedagogy [8]
[6][9][10] . To obtain the above goals, the various techniques
such as prediction, clustering, Relationship mining etc are
used.
II SSTS FRAMEWORK
The teaching learning process is a process of cognitive
thinking. The performance of students is based on their
attitude and relation with their teaching faculty members. Of
course it also includes the teaching methods or aids to
improve the students’ performance. Fig. 1 illustrates a
framework which helps the students’ to progress their
attitude and in academic performance. It relates Staff –
student (SS), student – Tutor (ST) and Tutor – Staff (TS) in
higher education.

III SOCIAL NETWORK ANALYSIS
Social network analysis [11] [5] [4] is the mapping and
measuring of relationships and flows between people,
groups, organizations, computers, URLs, and other
connected information/knowledge entities. The nodes in the
network are the people and groups while the links show
relationships or flows between the nodes. SNA provides both
a visual and a mathematical analysis of human relationships.
a. Experiment
The students’ database have prepared based on general
attributes such as name, age, year and cognitive attributes
base on attitude, behavior and knowledge distribution. It also
includes the SSTS framework attributes SSR, STR and TSR.
The framework is designed in a two way relation.
The students from the dataset are randomly mined by
k-means clustering using TANAGRA irrespective of their
year of studies. A group of 9 students from the dataset were
grouped into a cluster and each group is allocates to a tutor of
the department. Now a day, the faculty members use a good
teaching pedagogy to make the students to understand their
subjects. Learning process involves the knowledge sharing,
intelligence and utilization of resources and relationships.
Fig. 2. Social Network
Fig. 2. shows the social network formed by the whole
students’ dataset with the related attributes.
The work explored that the tutor plays an important role in
the improvement of students’ performance. The clusters
analysis showed the good interaction with the tutor –
students’ group and tutor – staff. The tutor – subject staff and
student – student interaction in the group leaded to take
special care both personal and in academics related. This
explored good academic results and identified it one of the
better framework for teaching learning process in higher
education.
This experiment is done by using social network analysis
software UCINET version 6. The grouped tutor clusters are
given as input and changed to UCINET matrix dataset. It is
then given as input to the DL compiler to link with the
interface. The output is found, and converted into cluster.
Fig. 3. described the cluster of tutor1.
Fig. 3. Tutor1 cluster
The blue dot determines the student as an attribute. The
arrow determines the interaction between the each student.
The cluster is strengthened by the tutor involvement.
Fig. 4. shows the cluster of tutor2.

Fig. 7. show the adequate multilevel clusters formed by the
tutor1. This revealed that there is a healthy interaction with
that group of max 3.

The proposed work extended the clustering in means of
students’ behavior, attitude of and interactions.
IV CONCLUSION
The research work explored a new SSTS framework in
teaching learning process. The students’ databases contain
information about the related attributes. The matrix data are
mined by using K means clustering from the large dataset
using TANAGRA. The clusters are grouped under tutor and
groups into matrix clusters. The experiment is carried out by
using Social Network Analysis (SNA) tool. The clusters are
analyzed and found fair interactions with the group and staff.
It resulted in improvement of students’ performance in
academics of higher education.

  • 1. ISSN: 2278 - 1323 International Journal of Advanced Research in Computer Engineering and Technology (IJARCET) Volume 2, Issue 6, June 2013 www.ijarcet.org 2034 Abstract— Educational Data Mining (EDM) is an emerging trend, concerned with developing methods for exploring the large data related to educational system. The data is used to obtain the Implicit and Explicit knowledge distribution. Educational Data mining methods are generally used to determine the performance of students, assessment of students and study students’ behavior etc. In recent years, Educational data mining has proven to be more successful at many of the educational statistics problems due to enormous computing power and data mining algorithms [1]. This research explores the applications of data mining techniques applied in educational field. The work explores SSTS, a new teaching learning process framework in higher education. The framework contains students database consists of various relational attributes. By applying data mining techniques to the database and mined the effective students’ knowledge distribution clusters using social network analysis. The analysis found that good student faculty relation network clusters and average percentile of effective knowledge distribution by students’ in higher education. INDEX TERMS— EDUCATIONAL DATA MINING, INTERACTION, RELATIONSHIP. SSTS FRAMEWORK, TUTOR. I INTRODUCTION Educational Data mining (EDM) EDM develops methods and applies techniques from statistics, machine learning, and data mining to analyze data collected during teaching and learning. EDM tests learning theories and informs educational practice. Learning analytics applies techniques from information science, sociology, psychology, statistics, machine learning, and data mining to analyze data collected during education administration and services, teaching, and learning. Learning analytics creates applications that directly influence educational practice [2][7]. Educational data mining researchers (e.g., Baker 2011; Baker Manuscript received June, 2013. M.Sindhuja Computer Science and Engineering, Sri Shanmugha College of Engineering and TechnologySelam, Tamil Nadu. Dr.S.Rajalakshmi, Computer Science and Engineering, Jay Shriram group of Institutions , Tirupur, Tamil Nadu. S.T.Tharani, Computer Science and Engineering, Jay Shriram group of Institutions, Tirupur, Tamil Nadu. and Yacef 2009) view the following as the goals for their research: Predicting students’ future learning behavior , Discovering or improving domain models that characterize the content to be learned and optimal instructional sequences, Studying the effects of different kinds of pedagogical support that can be provided by learning software, Advancing scientific knowledge about learning and learners through building computational models that incorporate models of the student, the domain, and the software’s pedagogy [8] [6][9][10] . To obtain the above goals, the various techniques such as prediction, clustering, Relationship mining etc are used. II SSTS FRAMEWORK The teaching learning process is a process of cognitive thinking. The performance of students is based on their attitude and relation with their teaching faculty members. Of course it also includes the teaching methods or aids to improve the students’ performance. Fig. 1 illustrates a framework which helps the students’ to progress their attitude and in academic performance. It relates Staff – student (SS), student – Tutor (ST) and Tutor – Staff (TS) in higher education. Fig. 1.

ISSN: 2278 - 1323 International Journal of Advanced Research in Computer Engineering and Technology (IJARCET) Volume 2, Issue 6, June 2013 2035 www.ijarcet.org III SOCIAL NETWORK ANALYSIS Social network analysis [11] [5] [4] is the mapping and measuring of relationships and flows between people, groups, organizations, computers, URLs, and other connected information/knowledge entities. The nodes in the network are the people and groups while the links show relationships or flows between the nodes. SNA provides both a visual and a mathematical analysis of human relationships. a. Experiment The students’ database have prepared based on general attributes such as name, age, year and cognitive attributes base on attitude, behavior and knowledge distribution. It also includes the SSTS framework attributes SSR, STR and TSR. The framework is designed in a two way relation. The students from the dataset are randomly mined by k-means clustering using TANAGRA irrespective of their year of studies. A group of 9 students from the dataset were grouped into a cluster and each group is allocates to a tutor of the department. Now a day, the faculty members use a good teaching pedagogy to make the students to understand their subjects. Learning process involves the knowledge sharing, intelligence and utilization of resources and relationships. Fig. 2. Social Network Fig. 2. shows the social network formed by the whole students’ dataset with the related attributes. The work explored that the tutor plays an important role in the improvement of students’ performance. The clusters analysis showed the good interaction with the tutor – students’ group and tutor – staff. The tutor – subject staff and student – student interaction in the group leaded to take special care both personal and in academics related. This explored good academic results and identified it one of the better framework for teaching learning process in higher education. This experiment is done by using social network analysis software UCINET version 6. The grouped tutor clusters are given as input and changed to UCINET matrix dataset. It is then given as input to the DL compiler to link with the interface. The output is found, and converted into cluster. Fig. 3. described the cluster of tutor1. Fig. 3. Tutor1 cluster The blue dot determines the student as an attribute. The arrow determines the interaction between the each student. The cluster is strengthened by the tutor involvement. Fig. 4. shows the cluster of tutor2. Fig. 4. Tutor2 cluster Fig. 5. and Fig. 6. following dendogram describes the cluster of tutor1 and tutor2 relation. Fig. 5. Dendogram of tutor1

Dendogram of tutor2 Fig. 7. show the adequate multilevel clusters formed by the tutor1. This revealed that there is a healthy interaction with that group of max 3. Fig. 7. Multilevel Clusters The proposed work extended the clustering in means of students’ behavior, attitude of and interactions. IV CONCLUSION The research work explored a new SSTS framework in teaching learning process. The students’ databases contain information about the related attributes. The matrix data are mined by using K means clustering from the large dataset using TANAGRA. The clusters are grouped under tutor and groups into matrix clusters. The experiment is carried out by using Social Network Analysis (SNA) tool. The clusters are analyzed and found fair interactions with the group and staff. It resulted in improvement of students’ performance in academics of higher education.
