CS UNPLUGGED

EXPLAIN A COMPUTATIONAL CONCEPT

A very useful way to do this is by combining tools such as Hello Ruby in Scratch and CS Unplugged's computer-free activities.

For example, using the Hello Ruby project in Scratch, we can work on the concept of sequence, which is one of the most basic concepts of computational thinking. In this project, Ruby has to follow a series of steps to achieve a goal, such as moving through different places, interacting with objects or completing tasks. Through interaction with the game, children understand that in order for Ruby to accomplish its mission, it needs to follow instructions in the correct order. This helps them visualize how a sequence works in programming, without the need for them to write code yet.

To reinforce that same concept, I would use a CS Unplugged activity, such as the human robot, in which students give step-by-step instructions to a partner to perform a simple task, such as reaching into the garbage can or picking up an object. If the instructions are not in the correct order or a step is missing, the “robot” will not be able to complete the mission, just as would happen to Ruby in the Scratch game.

This combination of the digital (with Hello Ruby in Scratch) and the physical (with CS Unplugged) allows students to understand that programming is not just about technology, but about logical and orderly thinking. In addition, both activities encourage active participation, teamwork and discovery learning, which are fundamental at the primary school stage.
