Observation Learning System

This is an innovative observation learning system which facilitates

the development of young students' collaborative learning through the integration

of the Internet of Things technology (IoT) and online private network.

The system is integrated with single board micro-controller hardware

and web application software.

The design has an image of an octopus because it has many tentacles which can represent the variety of sensors which acquire data from the surrounding environment. The name OBSY is created by the combination of “Observe” and “Octopus” which represents the key features of the OBSY system.

OBSY’s hardware offers

a real world remote observation


The system provides a secure connectivity via a simple WiFi router. Tablet devices with WiFi built-in can easily access OBSY by using a web application within the range of the WiFi area.


Students can monitor and acquire real-time data conditions such as temperature, light level, humidity and much more.

In order to prepare children for 21st century learning (problem solving, critical thinking, content creation and collaboration), the system has adopted the concept of inquiry based learning (IBL) and the 5E learning cycle model. This can encourage young students to learn and build new ideas based on their own understanding by providing real world questions, problems or scenarios.

Background & Context

With the ultimate goal to bridge the gap of digital divide and to address the unbalanced standards of education quality, the Thai government has distributed 800,000 tablet computers to grade one students nationwide in 2012. Our prior empirical research study showed that student’s learning experience and performance can be enhanced by the use of tablet computer. Therefore, we have decided to take up the challenge to design and develop an innovative educational learning tool which makes use of the existing low-cost tablet computers in rural underprivileged areas, where Internet connectivity is lacking.

What do we need to design?

- Design and build an educational learning device which focuses on science education. Study of how it can enhance students’ engagements and learning outcomes.

- Learning activity with OBSY has adopted the concept of science experiments which can enable students to learn and build new ideas based on their own understanding. This can allow students to observe and learn together, through social learning, how to understand real-world information through OBSY application.

- Build a low-cost, self-contained wireless network of sensor devices which work with existing schools’ tablet computers.
