Quasi-Experimental Design. 10 participants are randomly selected and split into two groups. Pre-Test (O) will be administered to both groups (X1,X2). The experimental group (X2) will receive the treatment (X) and both groups will receive the Post- Test (O) to determine the experiment’s success. The symbolic design :OX1X2-XO.

History: Unforeseen events/ teacher or students absence. Maturation: I don’t think the students would lose interest in this experiment because they will know that they are in an experiment and that would keep them excited to keep interest. Selection Maturation Interaction: My participant will not have different maturation rates. They are from the same class. Instrumentation: Instrumentation would not be changed and I do not see any conflict.

Ecological Validity: Because my sample size will be small they cannot be generalized. However, if the treatment is successful, the study can be reproduced with a larger sample. Selection-Treatment Interaction: Participants may be placed in groups. For instance, the purpose of this study is to see if students can work better in a group completing an assignment on a Wiki page. Some students may be more willing to work and others may not. I would want to include those who do not like to work into a group with those who do and see if their attitude towards work changes. Reactive Arrangements/Participants Effects: With regards to the Novelty Effect, I believe that the group which will do an assignment of the Wiki page will feel excited and more willing to complete a Wiki assignment than a traditional way.

Survey Results & Analysis rxy = There seems to be a strong positive relationship between the students who like to complete their work using pen and paper and who work better when they complete their work using pen and paper.
