– Decomposition – Abstraction – Pattern Recognition – Algorithms

Expressing an approach that a computer (human, machine or both)
can use to achieve a solution.
CT begins with an idea, a problem, a goal. A goal such as creating a video for my grandson’s 5th birthday connecting to a passion for basketball. Then connecting the dots to reach the goal using core computer science principles:

    1. Collect Data, Analyze the Data, Represent Data so Computer Understands
    2. Reduce Problem to Smaller Parts, Simplify Related Concepts to Essentials
    3. Design Algorithms – Write steps to solve a problem.
    4. Automate with Control Systems, Simulate Real World, Partner – Parallel Work

Critical Thinking + Computer Power = Computational Thinking
->>Making Decisions or Innovating Solutions

QUICK THINKING – Do you see CT components?

MORE THINKING – Was the student wrong to “break” the teacher’s rule?

All knowledge is answers to questions.  The more questions, the more knowledge. It is OK to question rules and directives. But, always follow them. Survival requires order. Success requires questions. CT builds a process to learn how to question, as a computer must be given coded rules to do anything.

Along with my math certification I earned my Computer Information Systems certification in 1985 from the University of Houston Clear Lake and my professor DrFrank@drsmatthews.net is still there. At that time programming was taught in computer math. The computer literacy MS standards in 1985 included programming. In 1989 I taught my first Computer Science course in Fort Bend ISD on an AppleIIE using Logo. I served on the first CS TEKS writing team directed by Karen Kahan and on the second draft which went to 15 courses.

I am now focusing on K5 CS Education, as I have experienced programming helps students learn math and use tools for computational thinking. This has been made easy with Blockley programming, as typing code and learning syntax is no longer needed. That ease of implementation and access to computing devices is the biggest change since Seymour Papert first used the term computational thinking in 1996. Jeannette Wing gave a speech in 2009 that brought this skill to the forefront. It is just in the last few years that this is reaching the mindset of administrators. I am in awe of what code.org has done to bring computer science to every child in one year.

Every 21st century student should have the opportunity to learn CS as the basics nurture creativity and problem-solving skills, and prepare students for any future career. Software and computers are everywhere, but less than one in ten schools teaches CS. 60% of STEM jobs are predicted to be in computer science.

See Computational Thinking for Education by Google and Google Education. And from the UK see the Barefoot Computing Summary. More about infusing in MS and HS Curriculum.
