    I just looked at SCYDynamics: what a great tool, I find it very intuitive to work with!! I’m looking forward to using it in the classroom.

    Is there a way for students to start the tool from the windows programs menu, instead of through the website?

    • Lars says:

      Yes, there is a way: Go to your computer’s Control Panel and choose Java. On the General tab, choose “View…” in the section “Temporary Internet Files”. There, SCYDynamics should show up, and you can select to “Install Shortcuts” (right-click or the arrow symbol in the top bar). This will create an icon to start SCYDynamics on your desktop, and you can move / copy it wherever you like.

      All the best!

    At first glance I am impressed by the tool. It is a great alternative in the Netherlands for Coach. My school is using Macbooks and Coach and many other Dutch educational tools require windows, so I am very pleased to have found this and I will be using it for sure in VWO 4, 5 and 6. One question: is it possible to include a “if …then… else” statement in any way in the model?

  3. Lars says:

    Hi Ade,

    currently there is no “if…then…else” statement available. However, we are aware that this feature would be useful in (Dutch) schools, and we may implement it soon. Also, we are thinking about changing to a Javascript-based version, that would be accessible even more easy in schools. We will post news about either direction in our blog!

    Hee, Simsketch werkt niet meer. Java geeft een melding dat hij hem niet kan openen.
    Hebben jullie nog een werkende versie?
