  We present a question bank consisting of over 250 multiple-choice and
true-false questions covering a broad range of material typically taught in an
introductory undergraduate course in numerical analysis or scientific
computing. The questions are ideal for polling students during lectures by
means of a student response system that uses clicker remotes or smartphones
running a suitable app. We describe our experiences implementing these clicker
questions in a recent class and provide evidence of their effectiveness in
terms of testing students' prior knowledge, gauging understanding of new
material, increasing participation, and especially improving student
satisfaction. Our conclusions are supported by a mid-semester student survey as
well as anecdotal observations. The question bank has been released as an
open-access educational resource under a Creative Commons license (BY-NC-SA)
for free use by the mathematics community.
