Is Scratch OOP?

Whether or not Scratch is Object-oriented is disputable. It definitely uses objects, namely sprites; however, you currently cannot dynamically generate sprites. In Scratch 2.0, however, cloning will be supported. This will allow for dynamically generated sprites.

Arguments against Scratch being OOP are:

  • Scratch does not support custom objects
  • Scratch does not support dynamic generation of sprites

Arguments for Scratch being OOP are:

  • Scratch supports sprites, which are objects.
  • You can access properties of sprites from other sprites.
  • Scratch 2.0 will support cloning, so dynamic sprite generation will become possible.
  • Lists can be used to create pseudo-objects

Alice

Alice is an innovative 3D programming environment that makes it easy to create an animation for telling a story, playing an interactive game, or a video to share on the web. Alice is a freely available teaching tool designed to be a student’s first exposure to object-oriented programming. It allows students to learn fundamental programming concepts in the context of creating animated movies and simple video games. In Alice, 3-D objects (e.g., people, animals, and vehicles) populate a virtual world and students create a program to animate the objects.

In Alice’s interactive interface, students drag and drop graphic tiles to create a program, where the instructions correspond to standard statements in a production oriented programming language, such as Java, C++, and C#. Alice allows students to immediately see how their animation programs run, enabling them to easily understand the relationship between the programming statements and the behavior of objects in their animation. By manipulating the objects in their virtual world, students gain experience with all the programming constructs typically taught in an introductory programming course.
