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.

Highlights

Overexposure to solar ultraviolet (UV) radiation is a risk for public health [1]
Radiation and protection by implementing Internet of Things (IoT) devices. It was enacted in formal primary education to answer the following research questions: RQ1: To what extent does a STEM environment implementing IoT devices affect 6th-grade students’ knowledge regarding UV radiation and protection?
There were no significant differences concerning the initial scores achieved by the experimental group (Mean = 14.67; SD = 2.12) compared with the scores achieved by the control group

Summary

Introduction

Overexposure to solar ultraviolet (UV) radiation is a risk for public health [1]. Excessive and prolonged exposure to UV radiation can lead to adverse effects, including some eye diseases, diseases associated with vitamin D insufficiency [2], premature aging, sunburn, and skin cancers [3]. Children are considered a high-risk population group [6] and are more vulnerable to the sun’s harmful effects compared to adults, as their skin is thinner and more sensitive, and even a short time outdoors in the midday sun can result in serious burns [6,7]. Perhaps the most aggressive type of cancer, are increasing, and so are other skin cancer types at increasingly younger ages [6,8,9]
