The researchers in this study undertook development of a webquest evaluation rubric and investigated its reliability. The rubric was created using the strengths of the currently available webquest rubrics with improvements based on the comments provided in the literature and feedback received from educators. After the rubric was created, 23 participants were given a week to evaluate three preselected webquests using the latest version of the rubric. A month later, the evaluators were asked to reevaluate the same webquests. The statistical analyses conducted on this rubric demonstrated high levels of reliability.
