WhizThinkers

This document discusses computational thinking and provides examples of how it can be applied. It defines computational thinking as using logical reasoning and problem-solving skills to solve problems. It gives examples of computational thinking in everyday life, sciences, archaeology, journalism, and more. The document also discusses teaching computational thinking to others using block-based programming languages like Snap, Scratch, and Pictoblox. Key concepts covered include sequences, loops, conditionals, events, parallelism, operators, and data.

Computational Thinking Mujitha Bai K B Founder, WhizThinkers https://whizthinkers.com/ Before 21st century- you had to understand how computer programs work In 21st century, you need to know how to make computers work the way you want
Is Computational Thinking just for - computer scientists - engineers - those who want to program or code on computers? What is Computational Thinking?
Computational Thinking holds the power of showing us the “how” of our everyday life
Computational Thinking in Sciences & for the Society Computational Thinking in Everyday Life Computational Thinking in Archaeology, Journalism, Humanities Jeannette Wing (Microsoft Research) (previously NSF, US) rather than saying that computer science is just for computer scientists, she has championed the idea that computer science is for everyone Computational Thinking can be a way of expressing oneself. Up until now, expressing our emotions had been limited to poetry, stories, painting, music What we often fail to notice is that computing is the base of all of this in one way or other The very core logic behind poetry, painting, and music is the same as coding
Computational Thinking Topics - What, Why & How - Computational Thinking versus Coding/Programming - Block-based Programming using Snap/Scratch - Pathways to take it forward
Computational Thinking – WHAT, HOW, WHY Block-based Language – HANDS-ON
Computational Thinking An Unplugged Activity – Robot in Action We can learn about computational thinking, or computer science concepts, without actually having a computer Robots: A) Can figure out problems on their own B) Follow instructions people give them in English C) Can do only simple things Robots can only do what they've been told to do, but we don't just tell them using words. In order to do something, a robot needs to have a list of steps that it can read. Today, we are going to learn what it takes to make that happen. Robot in Action
Real-world scenarios • Add numbers from 1 to 200 • Getting ready for school • Tying shoes • Getting parents to do what you want Is Computational Thinking just for - computer scientists - engineers - those who want to program
Computational Thinking – Real-world scenarios For which of these activities you can give a list of ordered instructions: A) Directions for getting ready for school in the morning B) Directions for making a sandwich C) Directions for studying for an exam Instructions you will give to your Computer A block-based language Snap! is a broadly inviting programming language for kids and adults that’s also a platform for serious study of computer science.
Computational Thinking - 101
WHY Computational Thinking • Must need for everyone in 21st century (just like read, write, arithmetic) • Own Creations – everyone aspires to make them come to life Coding / Programming = Understanding the programming language + Applying creativity + Problem-solving skills + Developing important computational thinking skills (useful for problem solving across many disciplinary areas) Computer Programming is just one subset of Computational thinking
HOW - Our Approach (Unplugged Activities) • Interactive Puzzles • WHY Interactive Programming Puzzles? • HOW to do an Interactive Programming Puzzle? Puzzle 1: Starter Code Video Puzzle 2: Starter Code Video Puzzle 3: Starter Code Video Puzzle 4: Starter Code Video
Computational Thinking – Quick Review • DEVELOP (Computational Thinking) - Using Computational Thinking Framework • Learn basic programming skills by creating interactive storybooks, animations, and games with Snap / Scratch, which is a block-based visual programming language for anyone new to coding • As young people design interactive media with Snap / Scratch, they engage with a set of computational concepts that are common in many programming languages • There are seven concepts, which are highly useful in a wide range of Snap / Scratch projects, and which transfer to other programming (and non-programming) contexts
Computational Thinking – Quick Review……. • Sequence: identifying a series of steps for a task • Loops: running the same sequence multiple times • Parallelism: making things happen at the same time • Events: one thing causing another thing to happen • Conditionals: making decisions based on conditions • Operators: support for mathematical and logical expressions • Data: storing, retrieving, and updating values

Computational Thinking – Basic Concepts We frequently exhibit aspects of computational thinking in our everyday lives! 1. Sequences & Loops • How do we give instructions to a robot or chat with a bot? • Give someone directions to a nearby store • Write out some dance moves 2. Variables, Events & Nested Loops • How can you learn about abstraction by creating a movie scene? • Make an interactive map using lists • You'll learn (and do it yourself - DIY) in this module 3. Conditional Loops, IF Statements • Want to make a game that ends when you "catch" an object? • Maybe you get points based on how close you came? • You'll do that in this class!

Editor's Notes

  1. I'm excited to work with you on computational thinking, and we will do this using block-based programming
  2. https://www.youtube.com/watch?v=mUXo-S7gzds First 50 seconds https://www.coursera.org/learn/block-programming-k12-educators-conditional-loops-if-statement/lecture/1v3Q3/welcome-to-the-the-computational-thinking-block-programming-in-k-12-education How many of you here know how to program or code? Even if you know how to program, you will still learn a lot Commonly used 1) explain a concept 2) ask people write a program that uses that concept E.g. Conditional IF (If month = January, NumDays = 31) How many here know what is Computational Thinking?
  3. Whether it's giving a simple set of instructions, or angry bird here can reach the green pig, or maybe it's calculating for a game,  how we're going to determine whether the red or blue team has scored a goal?  We'll learn how to do block-based programming so that you can control the computer. That is, not as a consumer of these games, but as creators or authors or designers of these mind-blowing games
