This study investigates the influence of social media on the values of female high school students in Saudi Arabia, as perceived by Islamic education teachers in the Asir region. Using a descriptive survey approach and a questionnaire distributed to a randomly selected sample of 226 teachers from a population of 555, the research highlights that social media significantly affects students’ ethical adherence, particularly in relation to Islamic conduct and dialogue. Teachers noted that social values were most impacted, with shifts in family relationships and exposure to inappropriate social practices. The findings further reveal that unregulated content fosters negative behaviors, while excessive use undermines academic performance, respect for teachers, and school interactions. In response, participants unanimously emphasized the need to raise awareness and integrate educational measures into the Islamic education curriculum to promote responsible and ethical engagement with social media.
