Logical and computational Thinking

Logical and computational Thinking

1. Computational thinking is the process to solve problems employing different techniques in a way that you can use the computer to solve the problem

   • Different techniques to use:
     • Abstractions the process of eliminating what is not necessary for find the solution
     • Breaking Down: It refers to brake the problem into a smaller pieces, and then the smaller problems are solved maybe the bigger one can be solved too
     • Simulation is another way to solve problems, with this technique we can simulate the result for a problem, before we try to do it
     • Algorithm development consists on a number of steps that we can replicate to automate process

2. Problem

   • A problem is a situation that deserves actions togo from undesired to an appropriate state in the future
   • The problems are applicable to different areas such as math,physics, sociology, psychology,
   • Techniques to solve problems
     • Trial and error
     • Abstraction
     • Divide and conquer
     • Development of algorithms
     • Brainstorming
   • Problems Solving have 4 main stages
     • Collecting information: It is necessary to investigate as much as possible to understand the problem.
     • Solution creation:Use the most possible answers to have more chances to solve the problem.For this strategy you can use trial and error until the situation is solved.
     • Solution Implementation: It starts whit the decision making.
     • Evaluation stage: Once the solution have been applied, you must be if the goals have been reached

3. Polya´s methodology

   • Understand the problem: Know what are you trying, search information, describe the problem with your own words
   • Define or design a plan: Examine the problem and see what technique can be used, try with chart,diagrams,equation, trial and error and find a sub-goal
   • Carry out the plan: Implement the strategy that you deciden in the step 2.
   • Look back: Check the results, look if your answer ir reasonable, determine if there are any other way to find another answer
