A classic method for learning programming with commands to control movement and drawing of an on-screen robot called a “turtle". The turtle hearkens back to early implementations in which children programmed a physical robot whose dome-like shape was reminiscent of a turtle.

A problem solving approach (also known as stepwise design) in which you break down a system to gain insight into the sub-systems that make it up.

|
A method of programming in which two programmers write code using a single computer. One programmer in the “driver” role uses the mouse and keyboard to actually write the code while a second acts as a “navigator", keeping track of the big picture, catching errors, and making suggestions. Programmers switch roles frequently and communicate throughout the process.

Detailed explanation-1: -Top down analysis is a problem solving mechanism whereby a given problem is successively broken down into smaller and smaller sub-problems or operations until a set of easily solvable (by computer) sub-problems is arrived at.
Detailed explanation-2: -A top-down approach (also known as stepwise design) is essentially the breaking down of a system to gain insight into the sub-systems that make it up.
Detailed explanation-3: -The top-down approach focuses more on the part where it breaks down the certain problem into much smaller parts. But on the contrary, the bottom-up approach first keeps its focus on solving the smaller problems and then integrating them into a whole and complete solution.
Detailed explanation-4: -Top-Down Design, is characterized by an extensive planning and research phase that leads into the development of a product. Bottom-Up Design, takes the opposite approach. While goals for a product are still outlined, the assembly of a product is done on a system by system basis.
