Program Overview

Device Engineering Labs (DEL) are physical labs that are set up in rural schools with an objective of providing hands-on learning of STEM concepts using devices that the students see and use in their everyday life and inculating design thinking to make things on their own. These labs systematically expose students to ‘learning by doing’ and thinking critically about daily and industry-based application of concepts. The training is imparted through a 3-year curriculum designed by IIT Madras and caters to students from classes 8 to 12. Trainers appointed by "Teach To Learn", IIT Madras and graduate students from IIT Madras provide the training in the respective schools. The teachers in the schools will also be trained for sustained running of the labs.

In a dedicated space with a minimum of 500 sqft, devices, tools and equipment necessary for teaching, hands-on training and learning are stored and set up. For example: Posters, workstations, a projector, screen, and speaker which enable easy interactions during demonstrations and large group teaching.

DEL Objectives

Hands-on-Learning Manufacturing By 3D Printing

Beneficiaries & Benefits

The primary beneficiaries of this program are Class 8th, 9th and 10th students


  • Hands-On-Learning of Scientific Concepts
  • Development of Scientific Thinking Skills
  • Enable Design Thinking
  • Culture of Fabrication & Manufacturing from School Level


Methodology for setting up and running the lab is discussed in the following schematic.


Step 1: School Identification and Lab Setup

Schools that can provide 1 classroom exclusively are chosen after discussing with the Education Board and School Head Masters. A Classroom size empty room is prepared to set up devices, tools and equipment necessary for running the lab.


Step 2: Initiation/Awareness Workshop

During the initial months after set up – one time workshop for all students in high school will be offered to raise awareness about the aim and objectives of the lab-How they can benefit and what is expected of the students and school.



Year I Training

During the first academic year after the setup of the lab, all class 8 students will learn science in fun way through “Tell me Why” question interactions. Some simple device demonstrations also will take place.There will be separate sessions for additive manufacturing where students will be introduced to 3D Printers and start making basic 3 dimensional shapes. Basic electronic concepts will be also introduced to the students.

Year II Training

At the end of year 1, an assessment will be conducted to filter interested students who have an aptitude and willingness to be part of the lab. Such students will learn device-based science in small groups. During the second term the devices will be working based on two or more concepts. There will be more advanced topics of 3D Printing where students will start designing using Computer Aided Designing (CAD) Software and making of assembly of two or more parts. In this year they will familiarize with basic coding and electronic prototyping boards like Arduino and some sensors and actuators.

Year III Training

Interested class 10 students will work on advanced equipment which they will improvise based on their hands-on and concept learning.In the class 10, the students will be introduced to making working models integrating electronic sensors, motors, microcontroller board, multiple parts made using 3D Printer.


Step 4: Teacher Training

Interested teachers from the school will get trained to run the lab so that it can sustain.

Device Engineering Training - Components

3-Layer Mentoring


Devices that we consider for our labs are every-day used and/or that we see around us; can be easily Dismantled & Assembled Back; Principle involved are covered in class VIII, IX, or X.

Year I:

Devices that primarily use 1 main principle/concept for its major functioning.
(e.g. cycle bell, soap dispenser, wind up toy, compass, stop watch, speedometer, spring balance, electric iron, hair dryer, binocular, Microphone)


Year II:

Devices that use more than one concept or principle for their functioning.
(e.g. stethoscope, weighing machine, BP Meter, induction cooker, fan, printer, microscope, mixer)


Year III:

Devices/equipment that are directly related to agriculture and other works in a village.
(e.g. motor in tractors, automation of agricultural equipment, weeder, nutrient applicator, water sprinkler, water pump, car screw jack, 3D printer etc)


3D Printing

3-Layer Mentoring

Year I:

This involves training about basic electronic parts like LED, motors, simple sensors and printing few objects like basic shapes, gears etc


Year II:

This involves printing objects or toys with assembly of 2 or more parts


Year III:

This involves training in Arduino Programming fundamentals and interfacing with basic sensors and actuators and involves printing of more complex models or toys
