Programming & Scratch Programming Learning to program is ultimately about learning to think logically and to approach problems methodically The building blocks out of which a programmer constructs solutions, meanwhile, are relatively simply Problem-Solving and Project-Design Skills logical reasoning breaking complex problems into simpler parts debugging problems developing ideas from initial conception to completed project sustained focus and perseverence Fundamental Ideas about Computers and Programming computer programs tell the computer precisely what to do, step-by-step writing computer programs doesn’t require special expertise, just clear and careful thinking Programming Common in programming, for instance, are "loops" (whereby a program does something multiple times) and "conditions" (whereby a program only does something under certain circumstances Also common are "variables" (so that a program, like a mathematician, can remember certain values) Statements In programming, a statement is simply a directive that tells the computer to something Think of it as a command or an instruction In Scratch, any block whose label reads like a command is a statement Statements One such block instructs a sprite to say something: Statements Another such block instructs a sprite to go to some location: Sequence To create a program in Scratch, you need to think systematically about the order of steps Boolean Expression In programming, a Boolean expression is an expression that is either true or false In Scratch, any block shaped like an elongated diamond is a Boolean expression One such block is: ... program in Scratch, you need to think systematically about the order of steps Boolean Expression In programming, a Boolean expression is an expression that is either true or false In Scratch, any... certain values) Statements In programming, a statement is simply a directive that tells the computer to something Think of it as a command or an instruction In Scratch, any block whose label...
