Ideas for Internal Assessment

This is by no means a definitive list of all the topics that students could choose to explore in their internal assessment. Students should choose something that they clearly understand and is easy to replicate. There are a few types of studies that should be avoided as the work does not meet the IB definition of a "simple experiment." They are in the "Danger Zone."The following topics are possible, but you have to be...

Can the students modify and replicate Perham & Vizard 2010??

Can the students replicate George Miller's Chunking experiment??

John Crane 21 August 2015 - 19:36

Dear Sonica - yes, any study that meets the requirements of manipulating one IV and measuring its effect on a DV is allowed. I am not really sure what this study is. The one I found was done on young children. Remember that the IB does not allow us to use young children in our samples.

In addition, yes, they can replicate Perham & Vizard, but they need to simplify it - for example, to no music and music that they like.

As for Miller's chunking experiment, what are the two conditions?

Thank yo john!!!
for miller- Condition 1- words are randomly shown. Condition 2- The same list of words are now grouped together and then shown. Hypothesis- Categorised words are easier to recall than uncategorised words. Is this correct?

Also, if you could guide me on how Rausher et al. study (Mozardt) can be conducted for HL??

John Crane 24 August 2015 - 17:01

If that is the study that they have found, that is fine. There are two clear conditions. As for Rauscher, you can carry it out with Mozart music and without. No need to do any major adjustments to the original.

There is a need to use one study/reference in the introduction for IA/SL, the one bein replicated. If more than one studies will be used ( lets say other 2 ) in oder to describe the issue under consideration in a more integratred way is there any penalty for that?

Hi, Mr. Crane! May I ask if my students can use two different treatment groups in both the independent samples design and repeated measures design? Thanks and God bless!

John Crane 27 August 2015 - 15:45

Dear Nassos

There is no penalty, but students do better to describe the theory upon which the study is based, rather than giving another study.

Nassos Tsiamis 31 August 2015 - 09:47

Thank you John, the answer provides a sound framework to deal with

John Crane 27 August 2015 - 15:45

Ellizabeth, I have answered that question in a different thread.
