To assess the effectiveness of two different ways of teaching reading, a group of 5-year-olds were recruited from a primary scho
ol. Their level of reading ability was assessed, and then they were taught using scheme one for 20 weeks. At the end of this period, their reading was reassessed, and a reading improvement score was calculated. They were then taught using scheme two for a further 20 weeks and another reading improvement score for this period was calculated. The reading improvement scores for each child were then compared. Read about each of the experiments below. For each experiment, identify (A) which experimental design was used; and (B) why the researcher might have used that design?
The researcher used Repeated measure design and this was used for the two experiment.
Repeated Measures design is an experimental design that involves the use of same participant in each condition of the independent variable. This means that For every condition of the experiment the same group of participants will be used.
Repeated Measures design is also known as within groups design.
Advantage- The use of same participants in each condition reduces participant variables i.e differences among individual are reduced since no new participant is used.
