Abstract

The importance of science students being able to reason across many orders of magnitude of size and time is referred to as scale literacy and has been highlighted as an important skill which enables students at all levels to communicate across disciplines and think more clearly about the implications of many scientific principles. We are developing an online instrument designed to assess students’ senses of scale and thereby identify the developmental stages of scale literacy among different student groups. We report here the initial results of this instrument and highlight a number of ways it will be refined to increase its sensitivity and precision.
