SOCIALCALC A Spreadsheet Activity for Computer Supported Collaborative Learning
AGENDA INTRODUCTION COLLABORATIVE LEARNING OLPC & SOCIALCALC LEARNING WITH SOCIALCALC LEARNING ON THE MESH LEARNING ON THE CLOUD CONTEXT BASED LEARNING CONCLUSION
Learning taking new dimensions – Organizational Learning Collaborative Learning Learning from the Environment With technology entering classrooms, what is next is what interests us! INTRODUCTION The secret of life is not enjoyment but education through experience. -Swami Vivekananda TECHNOLOGY EDUCATION COMPUTER SUPPORTED COLLABORATIVE LEARNING
COLLABORATIVE LEARNING Collaborative learning can be described as a group learning activity, characterized by two or more than two people, involved in the learning process, conducive to each other’s grasping abilities. • Develops social skills • Sharing of ideas from • different backgrounds • Problem solving • approach helps to • cultivate the student’s • mind in a progressive • manner • Enabling users far off to • interact in a learning • environment • Allows for interaction • beyond boundaries • Establishment of a • learning community Platform which hosts questions and discussions from the learners facilitating their learning curve to grow in a manner which advances their knowledge and at the same time assists their inquisitive minds.
COLLABORATIVE LEARNING THROUGH SPREADSHEETS • Problem Based Learning through Spreadsheets • An ideal bridge between arithmetic and algebra and allow the student free movement between the two worlds • Students look for patterns, construct algebraic expressions, generalize concepts, justify conjectures, and establish the equivalence of two models as intrinsic and meaningful needs rather than as arbitrary requirements posed by the teacher LOTUS SuperCalc Multiplan VisiCalc Plan Perfect Excel Google Docs
OLPC & SOCIALCALC One Laptop Per Child (OLPC) is an organization dedicated to create educational opportunities for the world's poorest children by providing each child with a rugged, low-cost, low-power, connected laptop with content and software designed for collaborative, joyful, self-empowered learning
OLPC & SOCIALCALC SocialCalc is a spreadsheet activity developed for functioning in the Sugar environment, OLPC’s software paradigm.
OLPC & SOCIALCALC • Features • Tabulation • Organization • Graphing and Calculation • Localization in different languages • Multi-user editing over the mesh network • Ability to read and edit single sheet Excel (.xls), • Lotus (.wk4) and other popular spreadsheet files Architecture
LEARNING WITH SOCIALCALC COLLABORATING ON SOCIALCALC Collaboration over a Mesh Network Collaboration over a Cloud Network
A type of networking wherein each node in the network may act as an independent router, regardless of whether it is connected to another network or not. LEARNING ON THE MESH • Allows for continuous connections and reconfiguration around broken or blocked paths by “hopping” from node to node until the destination is reached.
LEARNING ON THE MESH ARCHITECTURE
LEARNING ON THE MESH USE CASE
LEARNING ON THE CLOUD • The application residing on the school server is common to all the XO laptops. Hence, this removes the need to install the application on the network laptops. • Private Cloud Computing • All the systems integrated to the cloud access the application on the browser, the server handles the specific operations such as saving, etc.
LEARNING ON THE CLOUD ARCHITECTURE
LEARNING ON THE CLOUD HOW WE ACHIEVED IT Integration with the server Scaling the programme to support collaborative working Integration with Chat Activity Context Based Learning
LEARNING ON THE CLOUD USE CASE
CONTEXT BASED LEARNING Context = “any information that can be used to characterize the situation of an entity”. • Plot the behavioural profile of the students • Tailor make the course material to suit the needs of the students • Allow for interaction between different peer groups, and study their problem patterns • Extract resources from the content repositories to solve instantaneous problems • Allot assignments automatically based on the student’s perception of the topic, his problems and understanding of the same • Understand group psychology and group dynamics to plot students’ growth better
CONTEXT BASED LEARNING ADVANTAGES ON OUR SYSTEM The server acts as the host for all the XOs Any amount of activity occurring on the cloud is almost instantly saved on the server in the database Presence of the educator is not required at all times in order to monitor the study process The teacher can assume the role of the moderator, who can supervise the growth curve of the students
CONCLUSION • Demonstrated the use of technology for existing principles such as • Computer based collaborative Learning • Using SocialCalc spreadsheet activity as an example • The scalability of the same into a much more intelligent system that can synthesize context based learning environments
