Abstract:
Harshit heard of the social networking sites and started exploring them on the internet. To his
surprise he came across various educational as well as social networking sites that give
innovative and improved ways of learning. He gradually got prone to the facilities these
platforms offer which broadened his perspectives. He realized that this advancement in social
networking platform is providing him with much better options to engage with his
contemporaries, enhance his skills and access a wide variety of academic tools and resources
which most definitely add up to his convenience.
Harshit learn about LEARNOUT, a free social learning network of university and school students.
It offers a platform for its users where they can engage in activities like sharing study related
materials, counseling or simply connecting through a vast network of existing users from around
the world. Within a small time span of two years, more than 80,00,000 students registered for
the website and they use the website on daily basis. The distribution of the students in different
age groups was graphically presented and he got inspired as he thought himself that maximum

Figure 1: Histogram showing the number of students using learn-out in different age groups
The website offers user generated contents in 7 different languages including Italian, English,
Spanish, Polish, Russian, Serbian and Portuguese. The website is directly operated from its
respective regional head offices thereby providing a direct approach to the users. Learn-out also
has its free application available for all android devices. The website also has a dedicated 24/7
support team to assist the students in their matters. He surveyed a number of people and
recorded his finding on the percentage of users using this site in different languages:
Table 1: The percentage of users in different languages of LEAROUT is given in the table below:
Language Italian English Spanish Polish Russian Serbian Portuguese
Percentage
of users
11 57 6 4 10 9 3
He also discovered a site name TWOWAY which provides its students with a different approach
towards studies. It offers an interactive way of studying where students get to create and
animate flashcards. The website currently has about 1 million study content authored by the
students. The website also conducts different quizzical campaigns for the students and tracks
the progress of its users. The issues on which the campaigns were conducted are presented in
the form of pie chart.
Harshit also got a platform to spread awareness of the issues which he has to record in his
project work given by his teacher. He could collect the data globally and interpret it from
different perspectives.
Figure 2: The pie chart shows the campaigns conducted on TWOWAY in different subjects.
Mathematics was troubling him and he needed a special assistance in various concepts. He
received many resource materials to gain more knowledge and achieved higher level of learning.
The site name TROUBLE BUBBLE was the answer to his queries. TROUBLE BUBBLE offers a very
interactive way to the students looking for answers to the distressing questions. They can ask
questions directly from academic experts through their vast network. The following data shows
the number of question asked by students between 2:00 pm to 9:00 pm.
Table 2: The table below shows the average number of questions asked at different hours of the
day on TROUBLE BUBBLE.
Time 2 to 3 pm 3 to 4 pm 4 to 5 pm 5 to 6 pm 6 to 7 pm 7 to 8 pm 8 to 9 pm
Number of
questions
180 270 360 440 520 300 190
Harshit was pleased to know that he has the facility to get immediate answers to his queries
though his site.
