MIN

Computational thinking

• Computational thinking allows us to take a complex problem, understand what the problem is and develop possible solutions.

• We can then present these solutions in a way that a computer, a human, or both, can understand.

LESSON OBJECTIVES

TIME FOR TASK To develop your programming skills To understand how to provide a solution to a programming problem

MIN

Computational methods

• Problem recognition – describing the problem

• Problem decomposition – breaking down a complex problem or system into smaller, more manageable parts

• Abstraction – focusing on the important information only, ignoring irrelevant detail

LESSON OBJECTIVES

MIN

Abstraction

Removing any unnecessary details:

Example:

A builder who is planning to build 100 houses on a new estate may use a physical model of the new estate, or in the first instance, a plan on paper or on a computer screen. In either case the model will be greatly simplified. All the houses may be identical in size, colour and shape.

MIN

Problem decomposition

• Most problems needs to be broken down into sub-problems before they can be solved.

• Thin of any system starts off by presenting the user with a menu of choices. Each choice will result in different, self-contained modules.

• For example, using algorithms for sub-problems

MIN

Programming Task

• Each group has been given a programming task

• You need to use computational methods to try and solve the problem for analysis and design (make sure you include algorithms).

• After, you need to provide a solution to the problem

• Finally, you should show evidence of testing/evaluation

• Put everything in a PowerPoint, to teach the rest of the class how you solved it and how you used computational methods

• Support: use the support file on help for the activities/how to use programming techniques

• Extended: you should create a program that creates a GUI in Python
