不限名额的书面评估被用来确定本科生物学，化学/生物化学，和环境研究学生的认识和海洋酸化的理解。结果显示，除了对海洋酸化原因的新误解外，人口之间存在显着差异。过去几十年来，探索海洋酸化的科学研究显著增加。然而，很少有科学教育研究调查本科理科学生理解这一主题的程度。在所有本科生中，人们可能会预测理科学生最能理解海洋酸化。这些学生对海洋酸化有什么概念和误解？他们的意识和知识如何在不同学科之间进行比较？本科生物学，化学/生物化学，环境研究的学生，和科学教师进行比较，他们的认识和理解进行了评估。结果显示，与教师相比，学生对海洋酸化的认识和理解较低。与生物或化学/生物化学学生相比，更多的环境研究学生表现出对海洋酸化的认识，并确定了二氧化碳的关键作用。还发现了新的误解。这些发现提出了一个问题，即理科本科生是否准备好应对海洋酸化等社会环境问题。
Open-ended written assessments were used to determine undergraduate biology, chemistry/biochemistry, and environmental studies students’ awareness and understanding of ocean acidification. The results revealed significant differences among populations, in addition to novel misconceptions about the cause of ocean acidification. Scientific research exploring ocean acidification has grown significantly in past decades. However, little science education research has investigated the extent to which undergraduate science students understand this topic. Of all undergraduate students, one might predict science students to be best able to understand ocean acidification. What conceptions and misconceptions of ocean acidification do these students hold? How does their awareness and knowledge compare across disciplines? Undergraduate biology, chemistry/biochemistry, and environmental studies students, and science faculty for comparison, were assessed on their awareness and understanding. Results revealed low awareness and understanding of ocean acidification among students compared with faculty. Compared with biology or chemistry/biochemistry students, more environmental studies students demonstrated awareness of ocean acidification and identified the key role of carbon dioxide. Novel misconceptions were also identified. These findings raise the question of whether undergraduate science students are prepared to navigate socioenvironmental issues such as ocean acidification.
