Exposure to radio frequency electromagnetic fields has raised scientific and public concerns. It is necessary to acknowledge the adverse effects on the health among children using digital devices. Innovation in computers and mobile 5G phones, online games and use of social media applications are in a great boom. Study of various reviews give the current exposure effects due to these radiations. Here in this paper, we have included studies published in peer-reviewed journals between 2010 and 2023 which are based on empirical evidence and reviews. We have identified 57 published papers on health effects of digital devices on physiological and psychological aspects of children. Some of the major health related physiological problems are reported in the reviews are musculoskeletal problems, sleep disturbances, headache issues and eyestrain. Whereas Psychological problems highlighted in the reviews are poor concentration, memory loss, stress, depression etc. At present, there is insufficient data to draw firm conclusions about health effects due to the exposure of digital devices which are occurring in the everyday environment. Currently, there is little epidemiological evidence indicating that the use of digital devices causes adverse health effects.

The trainee teachers of B.Ed. course were divided in to two groups randomly as experimental and control group. Both the group was tested with self-prepared criterion reference test as pre-tests containing 20 multiple-choice questions and standardized problem solving ability test of Garg R. After the pretest, the control group was taught through traditional method of teaching and the experimental group was taught through concept mapping technique along with regular teaching. After completion of the unit, the students on both groups were given the same criterion reference test and problem solving ability test as posttest. Test scores were analyzed for any statistically significant difference in the scores on the test. The results from the present study indicate that concept mapping has a positive impact on B.Ed. trainee teachers' achievement in Educational Psychology subject and improved problem solving ability score.
