This essay summarizes the author's 10 years of experience at the Oklahoma Medical Research Foundation mentoring secondary school science teachers during 8-wk Summer Research Institutes. The summary is presented as a learning model, which we call the research dynamic. This model consists of three interlocked components: specified ignorance, peer interactions, and gateway experiments. Specified ignorance is based on the work of the sociologist Robert K. Merton. It is essentially the art of highlighting what is not known about a phenomenon but must become known for further progress. In practice, specified ignorance is framed as a hypothesis, a prediction, or a question. It is commonly the outcome of peer interactions, which are the second essential component of the research dynamic. Peer interactions are the inevitable outcome of having teachers work together in the same laboratory on related research topics. These topics are introduced as gateway experiments, the third component. The most important attribute of gateway experiments is their authenticity. These experiments, when first carried out, opened new scientific vistas. They are also technically, conceptually, and logically simple. We illustrate the research dynamic with a line of seminal experiments in biochemical genetics. We provide evidence that the research dynamic produced significantly positive effects on teachers' confidence in their professional preparedness.
本文总结了作者在俄克拉荷马医学研究基金会的十年经验,即在为期八周的暑期研究机构中指导中学科学教师。总结内容以一种学习模式呈现,我们称之为研究动态。该模式由三个相互关联的部分组成:特定无知、同伴互动和入门实验。特定无知基于社会学家罗伯特·K·默顿的研究。它本质上是一种突出关于某一现象未知但为取得进一步进展必须了解的内容的艺术。在实践中,特定无知被表述为一个假设、一个预测或一个问题。它通常是同伴互动的结果,而同伴互动是研究动态的第二个关键部分。同伴互动是教师们在同一实验室就相关研究课题开展合作的必然结果。这些课题作为入门实验被引入,这是第三个部分。入门实验最重要的特性是其真实性。这些实验在首次开展时开启了新的科学视野。它们在技术、概念和逻辑上也很简单。我们用一系列生物化学遗传学方面的开创性实验来说明研究动态。我们提供证据表明,研究动态对教师们在专业准备方面的信心产生了显著的积极影响。
