● 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.
