The introduction of programming education with object-oriented languages slowly migrates down the curriculum and is now often introduced at the high school level. This migration requires teaching tools that are adequate for the intended target audience. In this paper, we present a new tool, named <i>greenfoot</i>, for teaching object-oriented programming aimed at students at or below college level, with special emphasis of supporting school age learners. Greenfoot was designed by analysing and… 
Greenfoot demonstration
TLDR
This demonstration will show what Greenfoot is and how it can be used, and a demonstration of the Greenfoot environment and framework for introductory programming education.
A Study of Visualization in Introductory Programming
TLDR
A project to enhance student motivation and interest towards programming in the introductory programming course by applying visualization tool to lecture demonstrations and to the course assignments is described.
Game programming in introductory courses with direct state manipulation
TLDR
New functionality in the greenfoot environment is described, especially the addition of user interaction programming via direct state manipulation, which provides very low overhead graphical I/O handling at a level that makes it feasible to guide students to simple graphical game programming within a few weeks, while concentrating on fundamental object-oriented concepts in the structure of the program.
Visual Analogy for Understanding Polymorphism Types
TLDR
The design of a new visualisation tool that aims to assist in teaching the concept of polymorphism to students, along with correcting the misconceptions students have when dealing with this concept are presented.
On the Importance of Visualizing in Programming Education
TLDR
All three presented contributions to the research field of visualization should contribute to an understanding of abstract programming concepts starting with problem or application instead of syntax.
Supporting the development of interactive applications in introductory programming courses
TLDR
ELVIA provides a Java class framework that helps novice students of programming to automatically generate the graphical user interface of interactive applications, focusing in the classes and objects that compose the applications.
A study to build a new Visual Programming system: Fixed or contextual menu?
TLDR
A comparative study between two different user interface implementations for iVProg: context menu against fixed menu, showing that the construction of algebraic and logical expressions required a higher number of interactions in both interface versions.
Virtual sandbox: adding groupware abilities to Scratch
This paper highlights shortcomings of programming environments designed for novices to be used as a collaborative tool in game design. It also addresses these issues in the context of the bad image
Greenfoot: a highly graphical ide for learning object-oriented programming

Here, there and everywhere - on the recurring use of turtle graphics in CS1
TLDR
This paper has successfully used turtles to give students an intuitive understanding of central object-oriented concepts and principles such as object, class, message passing, behaviour, object identification, subclasses and inheritance; an intuitiveUnderstanding of recursion; and to show students the use of abstraction in practice.
