The heart of teaching and learning chemistry is the ability of the teacher to provide experiences that share a conceptually abstract mathematically-rich subject with novice learners. This includes not only chemistry concepts, but also knowledge about how to learn chemistry. Students' expectations for learning chemistry in the university classroom impact their success in doing so.Physics education research has explored the idea of student expectations with regard to learning physics, resulting in the development of MPEX (the Maryland Physics Expectation survey). We are adapting MPEX to develop a chemistry survey regarding student expectations for learning chemistry: CHEMX. In particular, CHEMX explores the role of laboratory in learning chemistry as shaped by Johnstone's work with the macroscopic, particulate, and symbolic representations of matter.Data collection from university chemistry faculty, undergraduates and graduate students in chemistry programs approved by the ACS Committee on Professional Training allows examination of differences in expectations across the disciplines of chemistry. Data collection from high school chemistry teachers examines the environment in which entering undergraduates develop their expectations. Collaborations with the POGIL Project (Process Oriented Guided Inquiry Learning, NSF Award 0231120) and the MORE Project (Model-Observe-Reflect-Explain, NSF Award 0208029) focus upon explicit efforts to shift student expectations and explore correlations with student achievement.

教与学化学的核心是教师提供经验的能力，这些经验与新手学习者分享概念上抽象的知识丰富的主题。这不仅包括化学概念，还包括如何学习化学的知识。学生对大学课堂化学学习的期望影响着他们的学习成绩，物理教育研究探讨了学生对物理学习的期望，并由此产生了MPEX（马里兰州物理期望调查）。我们正在调整MPEX，以开发一个关于学生对学习化学的期望的化学调查：CHEMX。特别是，CHEMX探讨了实验室在学习化学的作用，正如约翰斯通的工作与宏观，颗粒和物质的符号表示。数据收集从大学化学教师，本科生和研究生在化学专业培训ACS委员会批准的课程允许检查跨学科的化学期望的差异。从高中化学教师的数据收集检查进入本科生发展他们的期望的环境。 与POGIL项目（过程导向的引导探究学习，NSF奖0231120）和更多的项目（模型观察-反思-解释，NSF奖0208029）的合作专注于明确的努力，以改变学生的期望和探索与学生成绩的相关性。
