虽然学生可以通过参加以课程为基础的本科研究经验（CURES）来学习化学内容和探究实践，但有充分的证据表明，先前的经验塑造了感知。我们进行了一项案例研究，调查学生的第一次经验与治愈在上师化学工程实验室课程，利用访谈（n= 6），现场笔记，和书面反映（N= 31）。我们使用话语分析来描述学生的能动性，因为他们导航他们的不确定性，并使真实的研究意义。我们发现，学生们过去的经历塑造了他们对CURE的期望，有些人希望传统的学习支持与CURE不一致。为学生提供有限但重要的代理，使他们能够认识到可用的真实支持，包括寻求帮助本身就是一种代理形式;理解失败是研究的特有现象，而不是他们自己的缺点;并将自己定位为能够作为研究人员的社区来驾驭不确定性。我们的研究结果表明，教师应模型的不确定性和失败的研究和定位学生作为有价值的合作者和支持克服丰富的经验与食谱式的实验。
While students can learn both chemistry content and inquiry practices by participating in course-based undergraduate research experiences (CUREs), it is well documented that prior experiences shape perception. We conducted a case study to investigate students’ first experiences with a CURE in an upper-division chemical engineering laboratory course, drawing upon interviews (n= 6), field notes, and written reflections (N= 31). We used discourse analysis to characterize students’ agency as they navigated their uncertainty and made sense of the authentic research. We found that students’ past experiences shaped their expectations about the CURE, with some wishing for traditional learning supports misaligned to CUREs. Offering students constrained yet consequential agency allowed them to recognize the authentic supports that were available, including help-seeking as itself a form of agency; understand failure as endemic to research rather than their own shortcoming; and position themselves as capable of navigating the uncertainty as a community of researchers. Our results suggest that instructors should model uncertainty and failure as endemic to research and position students as valued collaborators and support for overcoming abundant prior experiences with cookbook-style experiments.
