John Crane provides an invaluable resource for all IB Psychology teachers. The site provides up to date studies and relevant material in the current news. It has become my go-to source for IB specific materials.

The InThinking IB Psychology website was extremely helpful during my first two years teaching IB Psychology. I have been able to easily gain access and insight into the IB curriculum.

An excellent resource which really supports my teaching. I particular have used the Paper 3 stimulus material - they have been a great resource especially the model answers.

    The Chi Squared Calculator
    Dear Amanda There is actually some debate about whether this is necessary. Usually it is applied if the frequencies are below 5. However, the IB is not asking students to make this correction. In fact, in all my time working with IB, I...

    Thinking and decision making
    Dear Jen Yes, this model can be used. And the "reliability of cognitive processes" content of "biases in decision making" may also focus on this - focusing on the heuristics. I have kept this very simple for my students and they have enjoyed...

    Hi John- you just mentioned a minimum requirement of 10 participants per condition. However, some of the classes that my students used ended up having less than 20 kids in the class. Is it really a requirement or just a recommendation? I always...

    Thinking and decision making
    Hi John, In the new Oxford text, this section is brutal. Systems 1 & 2 are in the "biases in thinking and decision making" section of this text. Can the information you presented above, regarding Dual Processing Systems 1&2, be used for...

    LP 4: Schema theory
