Publicly available, learner-generated questions were used to develop a methodology for advancing the exploratory stages of science education research. Data from four complementary online sources were collected, analyzed, and compared to the extant research literature on the science education topic of isotopes, a challenging concept for many chemistry learners. Data from People Also Ask features on a popular search engine, questions in response to two videos (n = 770), and questions posted to two question and answer websites (n = 600 and n = 29 213) were analyzed. Multiple findings not present in the literature were detected across all data sources in this study. Findings suggest that these online sources can serve to inform research in science education by providing a rich, ecologically valid, and accessible source of data. Implications include the use of existing online data prior to initiating research, writing assessments, and developing curriculum for science topics as a means to achieve more robust and generalizable findings and instructional resources.

PAA黑洞,Khan和Quora:通过现有数据源映射对同位素的理解

由学习者生成的公开可用的问题被用来开发一种方法,以推进科学教育研究的探索阶段。收集,分析了来自四个互补的在线资源的数据,并将其与有关同位素科学教育主题的现有研究文献进行了比较,这对许多化学学习者而言是一个具有挑战性的概念。来自“ People Also Ask”功能的数据,流行的搜索引擎上的功能,针对两个视频的问题(n = 770)以及发布到两个问答网站的问题(n = 600和n= 29213)进行了分析。在这项研究的所有数据源中都检测到了文献中未发现的多个发现。研究结果表明,这些在线资源可通过提供丰富,生态有效且可访问的数据源来为科学教育研究提供信息。含义包括在启动研究,编写评估以及为科学主题开发课程之前使用现有的在线数据,以获取更强大且可概括的发现和教学资源。
