Which of the following statements is describing the skill of, 'thinking abstractly'?

• Breaking a problem down

• Identifying the preconditions of a system, the inputs, outputs and reusable components

• Removing unnecessary details and including only the relevant details

• Identifying decision points for branching or iteration

• Means solving problems at the same time.

Which of the following statements is describing the skill of, 'thinking ahead'?

• Breaking a problem down

• Identifying the preconditions of a system, the inputs, outputs and reusable components

• Removing unnecessary details and including only the relevant details

• Identifying decision points for branching or iteration

• Means solving problems at the same time.

Which of the following statements is describing the skill of, 'thinking procedurally'?

• Breaking a problem down, allowing them the smaller problems to be solved.

• Identifying the preconditions of a system, the inputs, outputs and reusable components

• Removing unnecessary details and including only the relevant details

• Identifying decision points for branching or iteration

• Means solving problems at the same time.

Which of the following statements is describing the skill of, 'thinking logically'?

• Breaking a problem down, allowing them the smaller problems to be solved.

• Identifying the preconditions of a system, the inputs, outputs and reusable components

• Removing unnecessary details and including only the relevant details

• Identifying decision points for branching or iteration

• Means solving problems at the same time.

Which of the following statements is describing the skill of, 'thinking concurrently'?

• Breaking a problem down, allowing them the smaller problems to be solved.

• Identifying the preconditions of a system, the inputs, outputs and reusable components

• Removing unnecessary details and including only the relevant details

• Identifying decision points for branching or iteration

• Means solving problems at the same time.

What is meant by the term 'abstraction'?

• A simplified programming language used in program design

• Getting to a solution through the clear definition of the steps needed

• Including the necessary details and leaving out the unnecessary details

• Breaking a problem down into smaller sub-problems

When designing systems, it is important to consider what aspects are important to solve the problem and what are not. What is this known as?

• Abstraction

• Reality

• Programming

• Implementation

• Names of roads and motorways

• Wooded areas illustrated with trees

• Place names of towns and cities

• Students full names

• Student photos

• Students exam grade

• Student Payment details
