The most exciting new feature for me is the addition of Stride. Recordings of these events will be accessible afterwards for viewing retrospectively.ĭon’t forget to mark this date in your diary with a big red pen and join us in a couple of weeks! Posted in Greenfoot, Java, Stride, Teaching | Tagged Greenfoot, Teaching | 3 Replies Talk about Greenfoot and Stride – LondonĪfter concentrating on Greenfoot for some time, we have now worked on and released a significant new version of BlueJ: BlueJ version 4.0. 18:00 in Germany, Scandinavia, Italy, France, …Īfter this first event on 8 May, we will host Greenfoot Live every two weeks.The first Greenfoot Live event will be held on You will have a chance to listen to us talk, as well as ask questions. We will discuss educational aspects, as well as general programming topics, related to Greenfoot. The event is aimed mostly at teachers who use Greenfoot in their classes, but also at general Greenfoot users. Greenfoot Live will be a regular chat event where members of the Greenfoot team will be live online and talk about Greenfoot, among ourselves and with you – the users of Greenfoot.

In order to provide more ways to support teachers who are using Greenfoot (or thinking about using Greenfoot), as well as anyone else interested in Greenfoot, we are starting a series of live chat sessions: Posted in Research, Stride | Tagged Paper, Stride | Leave a reply Greenfoot LIVE

I would like to thank all our reviewers who contributed many useful comments and suggestions, especially Jens Mönig and John Maloney, and the special editions editor Franklyn Turbak. The rest of the special issue is very much worth reading as well – you can find it here. It has been published in a special edition of the Journal of Visual Languages and Sentient Systems (focussed on blocks programming). Kölling, Brown & Altadmri: Frame-Based Editing I’m glad it is out now you can read it here: It also describes related work and background (which you might like to read in its own right if you are interested in the history of block-based systems or structure editing), and a few small user studies. In parallel, we have worked on a comprehensive paper, describing the design ideas and rationale behind many of the detailed aspects. Then, more recently, we also incorporated Stride into BlueJ, making the new frame-based editor available to a much larger audience. Java support has been provided in BlueJ since its inception, while Stride support was added in 2017.We (that is: Neil, Amjad and I) have worked on Stride and its frame-based editor for about four years now, and there is a lot of work in it.įirst, Stride was designed and released as part of Greenfoot, and we wrote a few smaller papers about specific aspects of use cases around Stride.

In March 2009, the BlueJ project became free and open source software, and licensed under GPL-2.0-or-later with the Classpath exception.īlueJ is currently being maintained by a team at King's College London, England, where Kölling works.īlueJ supports programming in Java and in Stride. BlueJ implements the Blue environment design for the Java programming language. Blue was an integrated system with its own programming language and environment, and was a relative of the Eiffel language. BlueJ is an IDE (Integrated Development Environment). The development of BlueJ was started in 1999 by Michael Kölling and John Rosenberg at Monash University, as a successor to the Blue system. Object-oriented concepts ( classes, objects, communication through method calls) are represented visually and in its interaction design in the interface. This interaction facility, combined with a clean, simple user interface, allows easy experimentation with objects under development. The main screen graphically shows the class structure of an application under development (in a UML-like diagram), and objects can be interactively created and tested. It runs with the help of Java Development Kit (JDK).īlueJ was developed to support the learning and teaching of object-oriented programming, and its design differs from other development environments as a result.
