Greenfoot with Stride Workshop for Teachers - London
13 Oct 2017

Fig-3

Greenfoot with Stride – Programming after blocks (Key Stage 3)

At King’s College London, Strand, on 2 Nov, 17:00-20:00

Limited seats - RSVP

In this workshop, we will discuss how to teach concepts of traditional object-oriented programming with Greenfoot and Stride. We will introduce the tools of the environment itself, discuss the Stride language (which is quick and easy to learn), and present pedagogical considerations: How do you best teach with Greenfoot? How do you create motivation? What are good teaching examples? Teachers will go through hands-on exercises of using Greenfoot and Stride, and work with a number of programming examples that can immediately be used in a classroom.

Target Teachers: Teachers of computing courses, especially key stage 3. Some knowledge of programming (in any language) is assumed.

Stride is a language that is ideal as the next step after block programming (such as Scratch), and leads into full textual programming.

Greenfoot scenarios on your phone!
07 Sep 2017

Greenfoot-phone-600x376

Greenfoot scenarios are now automatically converted to HTML 5 when uploaded to the greenfoot.org site - this has a number of benefits, including that you can now run Greenfoot scenarios on a smartphone!

Scenarios upload to the Greenfoot.org site are now automatically converted to run as HTML 5. This has several advantages:

  • faster load times
  • the Java plugin is no longer required to play scenarios online
  • scenarios will now run on many smartphones and tablets
  • the UserInfo (high score) functionality works again with minimal fuss

Production of a HTML 5 scenario occurs through an automated translation of the original Java scenario into Javascript. This process has some limitations, which have been previously discussed; most importantly, Swing and AWT classes cannot be used which means that scenarios using the “java.awt.Color” and “java.awt.Font” classes will not translate successfully. Greenfoot 3.1.0 introduced replacements for these in the form of “greenfoot.Color” and “greenfoot.Font”, so we recommend upgrading to Greenfoot 3.1.0 if you are still using an older version.

In the near future, we also plan to allow running HTML 5 scenarios in a “full screen” mode (which should be particularly useful for running on phones and tablets), and to allow embedding scenarios in other web pages (much as you can embed videos from Youtube, for example).

Scenarios for which translation to HTML 5 was not successful can still be played by following the link to the legacy (applet) version, which requires the Java plugin. If you have created scenarios which didn’t translate successfully to HTML 5, viewing the scenario page while logged in should show you the log generated during the translation process which may give a hint as to what caused the failure (quite often, it will be due to use of an unsupported part of the Java API).

There may be some minor teething problems, so if you notice problems with the HTML 5 version of a scenario, feel free to discuss them in the discussion forum.

Greenfoot Live - A summer break

Happy Birthday Greenfoot!
31 May 2017

11

Greenfoot is 11 today - getting into teenage years.

It sounds like a very long time ago: Greenfoot 1.0 was released exactly 11 years ago today, on 31 May 2006.

The project has come a long way since then. Many people have worked on it, and many more teachers have helped with creating material, using it in classrooms and providing feedback. Greenfoot continues to be developed, adapted and improved - so here is to the next 11 years!

Greenfoot LIVE #3 coming up
30 May 2017

Greenfoot-live-240

Join us for the next live session, where we will talk about exporting to JavaScript.

We don’t generally have a fixed script for the LIVE sessions, but one of the topics we will talk about this week is the replacement of applets on the Greenfoot website with JavaScript versions, and the related opportunity of running Greenfoot scenarios on mobile devices.

Greenfoot Live

Programming Education Chat With The Greenfoot Team

Greenfoot Live started on 8 May and will be every two weeks. The second one will be on 22 May.

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. The event is aimed mostly at teachers who use Greenfoot in their classes, but also at general Greenfoot users.

We will discuss educational aspects, as well as general programming topics, related to Greenfoot.

You will have a chance to listen to us talk, as well as ask questions.

Greenfoot 3 is here
25 Oct 2015

Splash

Greenfoot 3 has been released – the biggest change in Greenfoot since its original release.

This version of Greenfoot adds the Stride language and its frame-based editor to Greenfoot.

Java editing, as we know it, is not gone: Java and its old editor are still present, and we expect that many people will still use Greenfoot with Java. Greenfoot 3 was carefully designed so that existing teaching material is still usable and existing instructions and tutorials continue to work.

There is, however, now the added ability to write classes in Stride. Stride is a Java-like language, and its attraction lies not so much in language features, but in its unique frame editor: Half way between blocks and text, it makes the entry into programming much easier than it ever was before with an essentially text based system. It also eases the transition for learners coming from block-based systems, such as Scratch, Snap or Alice.

The transition from blocks to text is a very pressing problem for many teachers at the moment, and it is frequently discussed at computing education conferences. Several research groups are working on addressing this issue.

Where most other systems, however, support the transition by providing a dual system – code can be shown as blocks or as text, with transitions between them – Stride goes a different way: Instead of having two views to compare, Stride provides a single system that offers the main benefits of both blocks and text in a single interface.

In doing this, Stride is uniquely placed to offer a new way to teach young learners who want to move on to full text-based languages.

To get a first impression of frame-based editing, you can read this short description.

And better still, download Greenfoot 3 and try it out yourself!

Happy programming,

Your Greenfoot Team

Start experimenting with Greenfoot 3
10 Oct 2015

Gf3

Greenfoot 3 is nearing final release. Get the Greenfoot 3 preview now, see what is new, and help us with testing.

Greenfoot 3 preview 2 is out now, and you can download it and try it out.

Greenfoot 3, with its addition of the Stride language and frame based editor for early introduction of programming, adds fundamentally new ways how you could introduce programming to beginners.

Try it now to see what your instruction could look like soon.

To get you started with Stride, we have a new worksheet - Meet The Greeps - and a few Stride version of some of our favourite scenarios here:

We would also welcome testing of existing, Java-based scenarios to make sure Greenfoot 3 continues to work well with all existing code and teaching material. So run your own scenarios with Greenfoot 3, and tell us how is goes.

You can post any feedback in this discussion thread.

Let us know what you think!

Greenfoot book - 2nd edition
06 Mar 2015

Cover-large

The second edition of the Greenfoot book is out now.

For this edition, the book has been significantly extended and improved. Several new chapters were added, more scenarios are introduced, and every chapter received a “Drill and Practice” section to reinforce the concepts learned.

These changes - together with many other improvements - make this an exciting new edition.

See more details here.

Greenfoot 2.4.1 Release
22 Jan 2015

Greenfoot-icon-256-shadow

Greenfoot 2.4.1 has been released. You can download it for all platforms.

This is primary a maintenance release with bugfixes, but it also includes a new Greenfoot.ask() method that allows you to request string input from the user.

Out now: Greenfoot 2.4
31 Jul 2014

Version-2-4

Get it while it’s fresh.

We have just released a new version of Greenfoot, version 2.4.

This version provides a number of bug fixes, and some functionality improvements.

The improvements include some new helper classes (which you can import into your scenario via the Edit/Import Class… menu). These classes make it easy to, for example, get live weather information, or access Google maps as the background image of your scenario. We will publish some more detail about how to use these shortly.

Text output has also been simplified, with a new showText method in the World class.

You can get Greenfoot 2.4 here.
