Content descriptor implement algorithms as visual programs involving control structures, variables and input

Elaborations

• • Elaboration writing and editing programs to solve problems using branching, iteration and variables in a visual programming environment, for example writing a program to draw a rotated shape a given number of times using Turtle Graphics
• • Elaboration writing programs that take input from the user or environment and storing that input in a variable for later use, for example asking the user how many shapes to draw in a circle and using that to calculate the number of iterations and angle to rotate each time
• • Elaboration writing programs that make decisions involving multiple alternatives, for example an interactive quiz that checks if the answer is correct, gives feedback and updates the score, or gives a final grade based on the score
• • Elaboration writing programs that repeat multiple steps based on the user's input, for example repeatedly drawing a shape a given number of times, shifting the position between each iteration
• • Elaboration stating the expected behaviour of a program, running the program to check it is correct and fixing any errors, for example 'when I press the left arrow key, the cat should move left, finding the cat moves right, and fixing it by changing the 10 to -10 to alter the direction'
• • Elaboration programming digital systems to perform automated tasks, such as closing gates, for example simulating the work of First Nations Australian rangers attempting to lure and capture feral animals
