Few studies demonstrate the impact of teaching chemistry embedded in a context that has relevance to high school students. We build upon our prior work showing that pharmacology topics (i.e., drugs), which are inherently interesting to high school students, provide a useful context for teaching chemistry and biology. In those studies, teachers were provided professional development for the Pharmacology Education Partnership (PEP) in an onsite venue (either five-day or one-day workshop). Given financial difficulties to travel, teachers have asked for alternatives for professional development. Thus, we developed the same PEP training workshop using a distance learning (DL) (two-way live video) approach. In this way, 121 chemistry and biology teachers participated in the DL workshops to learn how to incorporate the PEP modules into their teaching. They field-tested the modules over the year in high school chemistry and biology classes. Teacher knowledge of chemistry and biology increased significantly after the workshop and was maintained for at least a year. Their students ( = 2309) demonstrated a significant increase in knowledge of chemistry and biology concepts, with higher scores as the number of modules used increased. The increase in both teacher and student knowledge in these subjects was similar to that found previously when teachers were provided with onsite professional development.
很少有研究能证明在与高中生相关的情境中教授化学的影响。我们基于之前的工作展开研究,结果表明药理学主题(即药物)对高中生来说本身就很有趣,能为化学和生物学教学提供有用的情境。在那些研究中,教师们在现场场地参加了药理学教育合作项目(PEP)的专业发展培训(为期五天或一天的工作坊)。鉴于出行存在经济困难,教师们要求提供专业发展的替代方案。因此,我们采用远程学习(DL)(双向实时视频)方法开发了相同的PEP培训工作坊。通过这种方式,121名化学和生物学教师参加了DL工作坊,学习如何将PEP模块融入他们的教学中。他们在一学年中在高中化学和生物课堂上对这些模块进行了实地测试。工作坊结束后,教师们的化学和生物学知识显著增加,并且至少保持了一年。他们的学生(n = 2309)在化学和生物学概念知识方面有显著提高,随着使用的模块数量增加,分数也更高。这些学科中教师和学生知识的增长与之前为教师提供现场专业发展时的情况相似。
