Jen H's List: teaching ICT - programming

• to is followed by the name of the procedure. Subsequent lines form the  procedure definition. The word end signals that you're finished.

  • procedures
• Logo word is a string of characters. A Logo list is an ordered collection of  words and or lists. Numbers are words, but they're special because you can do  things like arithmetic with them.

  • words, lists

• To name arg1 arg2 ....

  • procedure... end with END
• Make "name x

  • assign to variable

• Repeat n [ instruction list]

• FOR [i start stop  step] [Instruction List]

  • FOR NEXT loop
• do.while, If, Ifelse Look these up in the help file for the  program.

• The Logo Programming Language, a dialect of Lisp,  was designed as a tool for learning. Its features - modularity, extensibility,  interactivity, and flexibility -follow from this goal.

  • Logo
• "Logo is the name for a philosophy of education and a continually  evolving family of programming languages that aid in its realization."  

  • constuctivism
• Constructivism views knowledge as being created by learners in their own minds  through interaction with other people and the world around them.

• Logo programming activities are in mathematics, language, music, robotics,  telecommunications, and science. It is used to develop simulations, and to  create multimedia presentations. Logo is designed to have a "low threshold and  no ceiling": It is accessible to novices, including young children, and also  supports complex explorations and sophisticated projects by experienced users.  

  The most popular Logo environments have involved the Turtle, originally a robotic creature that sat on the  floor and could be directed to move around by typing commands at the computer.  Soon the Turtle migrated to the computer graphics screen where it is used to  draw shapes, designs, and pictures.  

  Some turtle species can change shape to be birds, cars, planes, or whatever  the designer chooses to make them. In Logo environments with many such turtles,  or "sprites" as they are sometimes called, elaborate animations and games are  created.

• Another innovation of the mid-eighties was LEGO Logo. Mitchel  Resnick and Steve Ocko, working at the MIT Media Lab, developed a system  which interfaced Logo with motors, lights and sensors that were incorporated  into machines built out of LEGO bricks and other elements. Robotics systems with  Logo were not new, but the popular and well-supported LEGO TC Logo was a  commercial success which reached thousands of teachers and their students.

• MicroWorlds includes many extra-Logo features - drawing tools, a shape  editor, a melody maker, the ability to import graphics and sounds - that work  along with Logo to support the creation of multimedia projects, games, and  simulations.  

  MicroWorlds Logo includes a number of changes, the most significant being  multi-tasking, or parallel processing. Several processes can be launched  independently. This is invaluable when creating animations with more than one  actor - the car can drive off a cliff while the dog wags its tail while the fat  lady sings. This sort of thing is possible in a non-parallel Logo environment  but it is far easier and more natural in MicroWorlds. Multi-tasking has recently  been implemented in PCLogo for Windows, as well.

• This blog specializes in the new motion model of Flash CS4, and is brought to  you by team tween of Flash at Adobe. The blog will includes tips, techniques,  and info on tweening in Flash using the Timeline and Motion Editor (as well as  some stuff about motion runtime with code). From time to time, we might also  talk about ActionScript 3.0.
