Truly random is not fair over a lesson
Independent random picks mean a student can be chosen three times while another is never chosen at all, and over a forty-minute lesson that is the likely outcome rather than an unlucky one. With thirty students and fifteen picks, the chance that some particular student is never selected is about six in ten. Drawing without replacement until everyone has had a turn fixes this completely, and it is what people expect "random" to mean in a classroom.
Cold calling changes what the room does
Where hands go up, the same students answer and everyone else can opt out of thinking. Where anyone might be asked, everyone has to prepare an answer, and the evidence for this is reasonably strong. What matters is how it is done: a warning that a question is coming, time to think before anyone is named, and the option to pass without penalty turn it from a threat into an expectation. Naming the student before asking the question means only that one person thinks.
Track participation rather than trusting memory
Teachers reliably misjudge who has spoken, and the misjudgement is not random: quieter students are remembered as having contributed less than they did and confident ones as having contributed more. A count kept during the lesson costs nothing and is more accurate than a recollection at the end of it.

Frequently Asked Questions
Why not just pick at random each time?
Because independent picks let one student be chosen repeatedly while another is never chosen. With thirty students and fifteen picks, the chance a particular student is never selected is about six in ten, so it happens most lessons.
Does cold calling help?
The evidence is reasonably good that it raises attention, because everyone has to prepare an answer rather than opting out. How it is done matters: warning, thinking time and the option to pass turn it from a threat into an expectation.
Should I name the student before or after the question?
After. Naming first tells everyone else they can stop thinking. Asking the question, pausing, then naming keeps the whole room engaged for the part that matters.
What about students with anxiety?
An option to pass without penalty, agreed in advance, addresses most of it while keeping the benefit for everyone else. Exempting a student entirely is sometimes right and removes them from the participation the technique exists to create.
Why track participation?
Because recollection is unreliable and biased in a predictable direction: quieter students are remembered as contributing less than they did and confident ones as more. A running count costs nothing and is simply more accurate.
