Kodu – An independent project

Algorithm – an unambiguous procedure or precise step-by-step guide to solve a problem or achieve a particular objective. A set of instructions for achieving a goal or solving a problem.

Block –  a ‘chunk’ of programming or a particular graphic block or piece found in a graphical programming language such as Scratch or Kodu.

Command – a step or line of programming.

Debug – to detect and correct the errors in a computer program.

Decomposition - Breaking a problem down into smaller parts (a computational thinking concept)

Execute – to follow a series of instructions. The computer or robot follows the instructions in order to complete the program.

Input – data provided to a computer system, such as via a keyboard, mouse, microphone, camera or physical sensors. Information which is received by the computer from a keyboard, mouse or sensor e.g. pressing the left mouse button or space bar creates an input.

Logical reasoning – a systematic approach to solving problems or deducing information using a set of universally applicable and totally reliable rules.

Output – the information produced by a computer system for its user, typically on a screen, through speakers or on a printer, but possibly though the control of motors in physical systems. Also an action performed by the computer e.g. switching on a light, moving a turtle or sprite across the screen.

Program – A sequence of instructions written to perform a specified task on the computer

Selection – ‘when things happen’ - A programming construct in which the instructions that are executed are determined by whether a particular condition is met.

Sequence – to place programming instructions in order, with each executed one after the other.

Sprite – A graphical object that can be controlled by programming.

Variables – a way in which computer programs can store, retrieve or change simple data, such as a score, the time left, or the user’s name.
