Abstract
Prolonged exposure to ultraviolet (UV) radiation is linked to skin cancer. Children are
more vulnerable to UV harmful effects compared to adults. Children’s active involvement in using
Internet of Things (IoT) devices to collect and analyze real-time UV radiation data is suggested to
increase their awareness of UV protection. This quasi-experimental pre-test post-test control group
study implemented light sensors in a STEM inquiry-based learning environment focusing on UV
radiation and protection in primary education. This exploratory, small-scale study investigated
the effect of a STEM environment implementing IoT devices on 6th graders’ knowledge, attitudes,
and behaviors about UV radiation and protection. Participants were 31 primary school students.
Experimental group participants (n = 15) attended four eighty-minute inquiry-based lessons on UV
radiation and protection and used sensors to measure and analyze UV radiation in their school.
Data sources included questionnaires on UV knowledge, attitudes, and behaviors administered
pre- and post-intervention. Statistically significant learning gains were found only for the experimental group (t14 = −3.64, p = 0.003). A statistically significant positive behavioral change was
reported for experimental group participants six weeks post-intervention. The study adds empirical
evidence suggesting the value of real-time data-driven approaches implementing IoT devices to
positively influence students’ knowledge and behaviors related to socio-scientific problems affecting
their health.
