To sort these ideas into categories of pros and cons, you have to understand the connotation and side of the argument that the information supports. A positive effect of technology in classrooms would be in the pros, and negative effects would be in the cons section.
So, the first idea, “health effects of long-term radiation exposure,” represents negative effects of having daily use of electronics that emit radiation so it would be a con.
The second idea, “podcasts,” would be a pro. Podcasts are a great way to share ideas and educate the general public and could even be used in a teaching session in a classroom to assist with the lesson.
The third idea speaks directly of the “cons” that are present in technology in the classroom, so it is obviously a con. This study from 2003 would show the negative side of the argument.
The last idea, that tech in classrooms “improves academic performance,” is a positive effect. Therefore it would be considered a pro.
I hope this helps! :)
