Paperclickers: Affordable solution for classroom response systems

Abstract

We propose paperclickers, a low-cost classroom response system requiring a single mobile device for the teacher and cards with printed codes for the students, which results in a low-cost, easy-to-deploy solution that aims at broadening the adoption of active learning techniques in developing countries. We implemented paperclickers as a smartphone application, whose development history, with pitfalls and lessons learned, we describe in this paper. We also describe the results of the first round of usability tests we performed on the first prototype, indicating the feasibility of paperclickers, the opportunities for design improvement, and how they affected the current version of the software. A beta release of paperclickers is available for the public.

Towards the effective delivery of an affordable Classroom Response System

“…• Tests were based on two predeĄned scripts: performing the class roll-call (task 1) and performing a question poll (task 2). The testers were asked to follow scripts, indicating each activity they had to execute using paperclickers and in which sequence Ů further details can be found in Bindá [2015] and Oliveira et al [2017].…”
