The triangulation technique was used for the validation of this study (Mcniff, at al, 2010). There were
different gathering data methods, and the analyses were done from both of us, sometimes together
and sometimes separately. Two other teachers and the vice-principal helped us validate our work
through the whole process. They were our „critical friends‟ and we established trusting relationships
which became the grounds for giving and receiving critique (Mcniff and Whitehead, 2010).
