Negative Impacts of Smartphones on Lower Secondary School Students in Hanoi in the Context of Digital Transformation

In the context of the ongoing rapid digital transformation, smart devices have become increasingly integrated into human life, and children are no exception. This situation has led to many concerning consequences, such as declining academic performance, reduced emotional regulation, deteriorating mental well-being, and physical health issues. This paper focuses on examining the current situation and the negative impacts of smartphone use among lower secondary school students in Hanoi. Using a mixed-methods approach that combines qualitative and quantitative research through questionnaires and interviews, the study clarifies levels of dependence, purposes of use, negative effects, and especially students’ self-control abilities. The findings indicate that although students possess a certain level of awareness regarding the harmful effects, most still struggle to regulate their usage time, resulting in decreased concentration and reduced real-life social interaction.
