Mitch Resnick: TED “Learn to Code, Code to Learn”

Mitch Resnick is the Founder of the Lifelong Kindergarten program at the MIT Media Lab, and one of the creators of Scratch.

Scratch is an inherent programming language that makes it easy for children of all ages to create their own interactive stories, animations, games, music, and art, and share their creations on the web (Intro to Scratch from ScratchEd).

SCRATCH was developed by MIT for very young children to be able to program, but has been ear-marked as an elementary school products that is too simplistic for middle and high school students… but not any more!

The inherent SCRATCH programming interface is actually the key to 21st century education on the highest level of Bloom’s Taxonomy. SCRATCH’s drag-and-drop blocks resemble MIT App Inventor interfaces for creating apps on Android Phones.

You are not type-type-typing code, you are creating visual structures for complex computer science functions that you can transfer the understanding into other programming languages.

Basic Ideas of Scratch:

ScratchEd was created for Educators to be able to learn how to use Scratch.



Getting started with Scratch:

NOTE as of May 2013:  You currently CANNOT use Scratch 2.0 for LEGO WeDo. Please download Scratch 1.4.

Quote from Mitch Resnick 05/10/2013:

“Thanks for your message.

We definitely plan to support LEGO WeDo with Scratch 2.0, but it probably won’t be available for a few months. We plan to support WeDo as part of a more general “extensions” mechanism, which will allow people to download packages of “custom blocks” for specific external devices (like WeDo) or web services.
When the new features are available, we’ll announce them on the Scratch and ScratchEd websites.


Robots are mechanical mobile devices with software programming and sensors, and SCRATCH and LEGO WeDos provide both!

A discussion you can have with your students is what makes a robot:

  • Sensors
  • Movement
  • Energy
  • Intelligence

Directly plug in the LEGO WeDo USB to the computer with pre-loaded free SCRATCH, and the drag-and-drop robotics components will automatically appear in SCRATCH. If you have a motor raising and lowering, you need to put an interface on the screen to explain what is happening, and if the interface is interactive, we are hitting the core-level of robotics understanding that originally was going over student’s heads with LEGO Mindstorm NXTs because the software-hardware-interaction was not immediate. The robotic LEGO WeDo components that work in SCRATCH are a Distance Sensor, The Tilt Sensor, and a Rotating Motor.

My Blog Post about Scratch-ing the LEGO WeDo

The combination of elementary SCRATCH and elementary LEGO WeDo can tap the interest of all students from the elementary all the way to the high school level.
