ClassPal:An interactive doubt clearance application for classroom

Project Guide:Keyur Sorathia
Duration:Aug 2012-Nov 2012
Type: Team Project(2 Members)
Contribution:User Research, Focus Groups, Survey Design, Ideation and Analysis, Wireframes and High Fidelity Prototypes


In this project, we developed an Interactive doubt posting/clearance portal to enhance the learning experience for a lecture based classroom. In many ways, the portal mirrors students’ lives outside of school, where they communicate with friends via their cell phones or computers that interconnect with a slew of gadgets, participate in online social networks, enjoy gaming devices that respond instantaneously to their physical movements. The observations and primary user research/analysis were done within the premises of our institute, IIT Guwahati. The project got selected for publication in Journal Design For All March Edition 2013

Project Journey

1 Research Phase

The strategy followed for research was divided into two phases. First to get a wide range of general opinion on the context, we carried out surveys for a large group of people. Second phase was done to get the in depth knowledge of the matter and included activities like observations, user interviews and expert interviews

a.Observation and Survey

We conducted observation sessions in two types of classrooms to see the activities of students and teachers. Techniques like Shadowing, and Fly on the wall were used to observe and record behavior of students without interfering in their activities. A survey was also done ,firstly to identify the personality trait of a student and secondly a few opinion questions to know about their problems with the existing methods of teaching and interaction in class.

b.User Interview and Focus Group

Having done the analysis of the scores in the personality questionnaire, we picked a sample size of 8 people who reflected the extreme and moderate personality types for getting to know the different perspectives and experience of lecture based classroom learning with the main focus on doubt clearance in a room.As a part of carrying the research, we interviewed a few of the very experienced professors at IITG to know their side of the context with interactivity in a classroom..

2. Analysis and Ideation

There are four main components, individual devices for students, the central control for instructor, the main operating system or the host and the web. The system shows interactions that would occur in a classroom equipped with the proposed concept .Each individual device is a part of the larger host system with a governing Operating System. On the larger display is the feedback from this operating system. Communications can occur between any of the devices within the confines of the host(classroom) and the display is a flexible media to be set by the instructor. Information to and fro the web can be transferred too.

3 .Prototyping

Possible Features for our Proposed system

A new system for an interactive classroom experience with the assumption that each individual will have a handled device (Aakash Tablet) . The student can use it for a rich experience of learning by accessing various features like :

→Doubt clearance among peers during a live classroom or lecture
→Doubt clearance by professors (admin of the system)during a lecture or in the end of a lecture
→Promotion of doubt on the basis of no of students having the same doubt(liking a doubt)
→Answers provided for a doubt by the portal from the content provided by professor in form of E-books,lectures etc.
→Question bank/quizzes
→Student feedback of the professors
→Lecture notes,E-books
→Discussions forums


During the project we learned to apply different Interaction design methods and techniques. We learned about field studies, how to carry out observation, how to conduct user research and make sure it is useful in the end solution. The analysis of data gathered by research was an interesting stage where many insights started to develop and we were able to picturize a solution in our head.Our next step will be to test the solution proposed till a satisfactory result is gathered about the system loopholes and usability of the interface.
