What is Logo? Logo is a unique piece of software. In the purest sense, Logo is a programming language; it is a full-featured computer language derived from LISP, the language of artificial intelligence. More important, however, Logo is a language for learning. It is the right toll to teach the process of learning and thinking. Logo provides an environment where students assume the role of teacher. As a teacher, they must: • •

Understand the knowledge to be taught Plan an approach to impart this knowledge • Break the knowledge into small, understandable chunks • Know how to clearly communicate the knowledge • Established this new knowledge as a foundation for future learning • Be aware of and build on knowledge that the learner has • Br receptive to exploring new ideas as they appear • Respond to the learner’s (computer’s) misunderstandings and errors Students do this in logo by: •

Experimenting with logo commands to understand them and be confident in their use • Planning their task and organise it into various components • Writing a set of instruction to perform each small task • Constructing a program to perform all the tasks in the right order • Evaluating their program to assess whether the tasks is performed correctly. • Debugging their program by locating and correctly errors or restricting their approach Logo is not limited to any particular topic or area. However, it is most useful for exploring mathematics, as Logo’s turtle graphics provides a natural mathematical environment. Since turtle moves in distances and turn in degrees, studying geometry by constructing and investigating polygons and figures makes Logo a powerful learning tools. Logo by nature: Friendly

Logo is easily grasped; we can relate to the turtle and use it as an object to think with.

Extensible

Logo can be taught new commands and other commands can be built thereon.

Forgiving

Logo offers immediate feedback through helpful and informative messages.

3

Flexible

Logo is useful with preschoolers as it is with students of higher mathematics.

Powerful

Logo is a programming language, providing all the tools needed to create programs of any degree of sophistication.

So although Logo is a programming language, it is better thought of as a language for learning; a language that encourages students to explore, to learn, and to think.

A quick lesson in Logo Logo’s best known feature is a turtle, a triangular cursor used to create graphics. Even young children quickly learn to move and turn the turtle using easily-remembered, intuitive commands. For example, typing forward 50 moves the turtle forward 50 pixels (Screen dots). Typing right 90 turns turtle right (clockwise) 90 degrees.

By combining these commands, it is easy to draw a square

4. Exercises (a)

Programming language of a circle of square 4

Output

(b)

The design below was created using two procedures that are more complex. They use procedure inputs to represent the line lengths and 5

turning angles, recursion to call the same procedure again, and a condition statement to procedure stop. You would enter the name of the main procedure design to run the program.

Conclusion This Logo software is now used from kindergarten to the university level. A lot of design could be used to draw design as shown above. Logo fits easily into mathematic classes, but can also be used to explore other areas.
