Presentation Transcript

  1. Programming Languages: Scratch Intro to Scratch

  2. Lower level versus high level • Clearly, lower level languages can be tedious • Higher level languages quickly developed to make programming faster

  3. Which language? • There are numerous languages to choose from • Examples include: • C/C++ • Java • Python • Ruby • Ada • ML • Prolog • Matlab • …

  4. Different considerations • Different languages are good for different tasks! • Examples: • C/C++ is extremely fast, but also takes longer to learn or code in • Matlab is much slower, but is optimized for being easy and (relatively) fast on matrix operations • Java will run on any machine (without the full packages being installed), but is slow in comparison to C/C++

  5. Scratch • We’ll start with a programming language that is relatively easy to learn and use immediately • (It’s also free - you can download it at home) • Advantage: while the syntax is similar to other programming languages (while, if, etc.), it is also a bit easier to use

  6. Getting started • So - find scratch on the computer in front of you. • Open it.

  7. Quick overview

  8. Getting started • For the rest of today, we’ll work through the “getting started with scratch” guide • Experiment and have fun! • Next week, we’ll explore scratch syntax a bit more in depth, and talk about programming in scratch
