Classroom experiments as a replication device

A string of failed experimental replications in many disciplines have shed light on the low levels of replicability of published research. There is an increasing call for more replications to be conducted to bring credibility back to academic research. Despite this, there are few incentives for researchers to conduct replicating studies. They are costly in terms of time and money, and are difficult to publish due to the competitive nature of publication, where journals seek a high degree of novelty and contribution. This paper proposes a low-cost method of replication: conducting replication experiments in a classroom context. As a case in point, we present results from a simple replication of Weber's (2003) “`Learning' with no feedback in a competitive guessing game”.
