Abstract
In this study, we developed online learning materials with the aim of improving the scientific literacy of consumers, and verified the effect in Randomized Controlled Trials using crowdsourcing. Ten useful conditions were found to distinguish science from pseudo-science based on knowledge of scientific philosophy and science sociology. Three of these, Repeatability, Predictability and Public Openness, were selected as learning concepts. The result of the study showed a significant understanding for "concept explanation + developed material" for every condition, compared with "concept explanation alone". The maximum effect size of 0.54 was obtained for Public Openness, which suggests certain effectiveness in online learning of this concept.
