This is another form of student-directed randomized scripture reading. Students stand to read a verse and then call the name of someone else to stand and read the following verse. The kids are "popping" up to read.
This is also a good technique when you're doing Everybody Writes (each student writes a a brief response to something and then reports).
This is probably not a technique I'd use with adults, who can get very persnickety if called on out of the blue, UNLESS I had already established a good repoire with the class, had taught several lessons, and I knew that everyone in class could read.
