Participants were asked to complete the “Mathematics Attitude Scale” (MAS) and took part in the mathematics classes of 6 weeks using either a social learning environment involving cartoons or teacher-centered activities …show more content…
Secondly, within the experimental group, 5 participants were selected by the researchers using a purposeful sampling method. They were considered most suitable for the propose of the research and could represent the opinions of the experimental group. Purposeful sampling method is where the researchers choose whom to be included in the sample based on their own judgement. There can be a high possibility of experimenter bias threatening the internal validity of the study. The judgement of the researchers can be very subjective and arbitrary. They may be biased towards their expected result and affect the accuracy of their analysis.
