My child just built a radio and we hear music

Informal education can be a vital part of a person’s learning experience, thus it is important to continue studying its effectiveness and consider improvements. To that end, we studied participants who built their own AM radio at three School of Earth and Space Exploration open house events at Arizona State University. For this qualitative research study, we audio recorded and transcribed interviews of 41 adults after they completed the activity. Median duration of interviews was 3 minutes.

This is consistent with previous studies since over 50% of participants are typically parents. We further grouped each category based on their Science, Technology, Engineering & Math (STEM) background: No STEM Background (NSB), Some STEM Background (SSB) and Expert Electronics Background (EEB). STEM backgrounds of parents were evenly distributed, with each group (i.e., NSB, SSB & EEB...
