      • Thinking computational thinking is only about coding
      • Confusing memorization with problem solving
      • Assuming it removes creativity
      2. Which of the following is the correct way to describe computational thinking?
      easy
      A. A technique to memorize computer commands.
      B. A way to write long paragraphs quickly.
      C. A process to avoid solving problems.
      D. A method to solve problems by breaking them down into steps.

      Solution

      1. Step 1: Identify the definition of computational thinking

        Computational thinking means solving problems by breaking them into smaller steps.

      2. Step 2: Match options to this definition

        A method to solve problems by breaking them down into steps. matches perfectly; others describe unrelated ideas.

      3. Final Answer:

        A method to solve problems by breaking them down into steps. -> Option D

      4. Quick Check:

        Definition matches A method to solve problems by breaking them down into steps. [OK]
      Hint: Look for problem-solving by steps description [OK]
      Common Mistakes:
      • Choosing options about memorization or writing
      • Confusing computational thinking with typing skills
      3. Consider this flowchart for solving a problem using computational thinking:



      What is the correct order of steps in computational thinking?
      medium
      A. Understand problem -> Break into steps -> Solve each step -> Combine results -> Done
      B. Solve each step -> Understand problem -> Combine results -> Break into steps -> Done
      C. Combine results -> Break into steps -> Understand problem -> Solve each step -> Done
      D. Done -> Understand problem -> Break into steps -> Solve each step -> Combine results

      Solution

      1. Step 1: Analyze the flowchart steps

        The flowchart shows a logical order: first understand the problem, then break it down, solve parts, combine results, and finish.

      2. Step 2: Match options to this order

        Only Understand problem -> Break into steps -> Solve each step -> Combine results -> Done matches the flowchart's correct sequence.

      3. Final Answer:

        Understand problem -> Break into steps -> Solve each step -> Combine results -> Done -> Option A

      4. Quick Check:

        Correct step order = A [OK]
      Hint: Follow logical problem-solving order in flowcharts [OK]

      A. It may cause confusion and mistakes because the problem isn't clearly understood.
      B. It saves time and is the best way to solve problems.
      C. It shows excellent computational thinking skills.
      D. It means the problem is too easy to solve.

        Jumping directly can cause confusion and errors because the problem isn't fully understood.

      3. Final Answer:

        It may cause confusion and mistakes because the problem isn't clearly understood. -> Option A

      4. Quick Check:

        Skipping steps causes confusion = B [OK]
      Hint: Always break problems down before solving [OK]
      Common Mistakes:
      • Thinking skipping steps saves time
      • Assuming skipping steps shows skill
      • Believing all problems are easy
      5. You want to plan a trip with friends using computational thinking. Which of these steps best shows applying computational thinking to this real-life problem?
      hard
      A. Ignore the trip details and just focus on the destination.
      B. Decide to go without any plan and figure things out on the way.
      C. List all tasks like booking tickets, packing bags, and planning routes separately, then complete each.
      D. Ask one friend to do everything without sharing tasks.

      Solution

      1. Step 1: Identify how computational thinking applies to planning

        Computational thinking means breaking a big task into smaller tasks and solving each step clearly.

      2. Step 2: Evaluate options for applying this idea

        List all tasks like booking tickets, packing bags, and planning routes separately, then complete each. breaks the trip into tasks and plans each, matching computational thinking. Others ignore planning or teamwork.

      3. Final Answer:

        List all tasks like booking tickets, packing bags, and planning routes separately, then complete each. -> Option C
