● Motivation● Introduction● Objectives ● Raspberry Pi for Secondary Education● Evaluation of Raspberry Pi for Secondary
Education● Conclusions and Future Scope
Motivation
● Use of Information and communication Technology in learning.
● Infrastructure, accessibility, linguistics aspects of pedagogy.
● Expensive devices – smart interactive white boards, projectors, computers are not feasible.
● Open hardware devices that are relatively cheaper than these devices can be brought to use in local public schools.
Motivation
● Open Hardware means hardware with less licensing issues.● Texas Instruments released miniature computing open hardware devices such as
Panda Board, Beagle Board, Beagle Bone for DSP applications like speech,music and video processing.
● Other open hardware devices include Cubie Board, Rascal, Open Pandora.● These devices are highly expensive of the order of hundred
dollars with capabilities of past generation computers.
Introduction
● Evolution of low cost hardware – Raspberry Pi.
● Capabilities of the order of emerging smart phones.● Flourishing of Raspberry Pi – close to 2 million devices
sold.●

Introduction
Raspberry pi around the world
Raspberry pi for students
World around with Raspberry Pi
● Raspberry Pi used in several applications such as Robotics, Meteorology, Home automation, Gaming devices.
● The major aim of Raspberry Pi in the countries like U.K, France, U.S.A was to impart animated programming skills using applications such as scratch and pypy.
● But it is not the only way to look at Raspberry Pi.
Objectives
● Design a cost effective model for secondary schools
● Observe the consequences of the model through statistical data
● Contribution to the community with the obtained results
Raspberry Pi for secondary education
● Video talks in classroom● Slide show based content● Document viewing and editing● Support for vernacular languages● Virtual Network Computing● Educational tools● Document printing
Raspberry Pi for secondary education
● Video playing – omxplayer and Raspbmc
$omxplayer -o hdmi /place/of/file.mp4
Raspberry Pi for secondary education
Vernacular language support – intelligent Bus
$sudo apt-get install ibus ibus-m17n im-config
install the necessary fonts. ttf-telugu-fonts
Run i-bus preferences in the GUI environment, and add telugu as your desired input method.
Run in a terminal:
$ im-config -n ibus
Logout and re-login.
The ibus input method can be activated and deactivated in all applications with the keys configured (default: Ctrl + Space).

Raspberry Pi for secondary education
● Applications selected from kde-edu, skole linux, tux.
● Optimised SD card for secondary schools to replicate.
● Network of several other devices with Raspberry Pi.
● Similar functioning to that of a desktop computer.
Evaluation of Raspberry Pi for secondary education
● Video talks, slide shows presented in the local language i.e., telugu in view of the students in the schools.
● Collaborative laboratory activity.● Sample spaces of different sizes and different
classes were considered for the current work.
