Researchers might be wondering whether the use of social media by students raises any ethical issues? It is my opinion that with the astronomical increase in the use of social networking websites or platforms by students, ethical issues are progressively important. The astronomical increase in the use of social networking platforms by minors raises ethical questions in school ecologies. This study investigated the ethical issues in social media usage among secondary school students in a developing context. A semi-structured questionnaire that elicited information on the school children's home background, social media operated, and mode of connection to the social media was used to collect data. The questionnaire gave the students the opportunity to write their responses to the interview questions freely. Mixed methods such as constant comparative techniques and descriptive statistical methods were used to analyze data from the one hundred and thirty school children that participated in this research. The results indicated that Facebook is the most operated social networking website by the selected schoolchildren. Most of the schoolchildren operating the popular social networking accounts signed up before the age of thirteen with the help of their biological sisters and brothers. Themes such as cyber pornography, sexting, cyber stalking, cyber bullying, cyber hacking, and abusive language emanated from the individual qualitative interviews. The concluding part of this article answers questions on the impact of new communication technologies on psycho-social adjustment of school children in developing countries.
