Many teachers work on social networks out of school. They participate via this social networking in maths forums where they exchange views on various maths issues with their students and other maths teachers (ή colleagues). The purpose of this research paper is the assessment of the afore-mentioned social networks taking into account the opinions held by maths teachers aggregated using a method similar to the SWOT technique, i.e. by completing electronic questionnaires distributed via email. The participants' answers were then grouped based on criteria defined by the researcher. The relative weight of each criterion was determined at a later point in the survey. Teachers should decide if some criteria were more important than others and give a higher arithmetic value to them. The conclusions drawn is that the above-mentioned procedure is really useful since it can pose analytical questions-after having researched new suggestions and initiatives-that will shed light to aspects of the external and internal environment.
