Best Practices for Field Days: Validating an Informal Science Education Field Day Observation Tool

Abstract

A study was conducted at the Metro Children’sWater Festival (CWF) in St Paul, Minnesota in the fall of 2008 where 44 schools and more than 1,200 fifth grade students participated in the one day event. The purpose of the study was to assess the validity of an observation tool for informal science education around Field Day programs. Content validity (Modified Delphi) and coder reliability of the observation tool was established the previous years (NSF, #0635559). Items from the observation tool were mapped to students’ evaluation questions to determine the degree to which observed characteristics of the field day are aligned with student perception. It is conceivable that they don’t align. Students’ assessment of their experience is based on factors that have little to do with what educators care about. Significant correlations support the validity; lack there of, on the other hand, does not indicate that the tool isn’t valid.
