UNPLUGGED ACTIVITIES• Unplugged activities are activities to learn how to thinkcomputationally without using a computer• There is much evidence that appropriate use of unplugged
pedagogical techniques can be very effective and motivational for thelearner(Waite, J. (2017) Pedagogy in teaching Computer
Science in school: A Literature Review)

The guidebook analyses three types of activities.

First, "coloring activities" to develop computational thinking. Then "mathematics andSTEM activities" to promote respectively mathematical and STEM thinking.
The guidebook was edited by• Kritsachai Somsaman, SEAMEO STEM-ED, Thailand• Masami Isoda, CRICED, University of Tsukuba, Japan• Roberto Araya. CIAE, University of Chile, Chile

The project aim is to provide primary teachersmaterials for contributing to Develop
Computational Thinking on Artificial Intelligenceand Big Data Era for Digital Society
In this intervention we will comment chapter 1“coloring activities”.
“Coloring activities" encourage the developmentof computational thinking through naturallanguage, which is foundational for using
generative AI and reasoning for programming

Task B is an open task which provides the opportunity to reflect on the wholeprevious activities. It is a first approach to the construction of prompts.

How to provide effective “Prompts”

Paint stars (real stars are…)

Develop the story of magic

Various representations

setting the steps of the sequence

More dogs, Only one dog
Setting condition and contextual meanings

Closing commentaries for Coloring Activities Guide• Coloring activities are amused for children• Reflection can be added to illuminate coloring activities

As teachers imagine the objective of the task,
they can lead their students to achieve the goal.
• These coloring activities were produced to develop Computational Thinking on
Artificial Intelligence and Big Data Era for Digital Society• The Guidebook provide insight for teaching

Well Done!
