This paper is analyzing feedback collected from Greek high school teachers, in order to answer questions regarding the use of Information and Communication Technologies (ICT) as part of their teaching practices in Greek schools. Various hypothesis tests are presented, in order to focus on perceptions, look into possible problems and see how teachers of different profile and specializations apply ICT in their teaching. A special focus is placed on philogists, as the most populous but also less technology-related subject, content-wise. In particular, an online survey was prepared, aiming at collecting information regarding the use of ICT in Greek schools. This information is analyzed across various demographic and profession-related variables concerning teacher's age, gender, specialization, type of technology used, familiarization with ICT, motivations. A total of 309 respondents reacted to the questionnaire, over a period of about two months in 2019. The questionnaire consisted of 31 questions in total. The analysis that follows is both descriptive and statistical, while it intends to provide answers and correlations regarding the most striking questions and hypotheses.
