3. Research methodology
For the purposes of data collection during this experiment, we used appropriate qualitative research method
(Creswell, 2013) with descriptive approach, mainly through participant observation and interviews (Seidman, 2012).
Participant observation was public and with moderate researcher involvement while the interviews were
unstructured as that was most suited for our target group.
Subjects for the experiment were chosen between 2nd and 3 rd grade of elementary school children because it was
determined that they did not have any formal education regarding computer science concepts since our last year’s
(2013.) encounter. Sampling was judgmental (Kumar, 2012), done by the teacher who selected the children that
were generally more interested in selected topic. Subjects were divided into four different groups, each one
consisting with 9 – 12 children. Figure 4. shows one group of the children during the experiment, along with the
teachers observing and collecting data.
