科学家们严重依赖树木年轮记录来更好地了解过去千年的气候变化。树木年轮也可以用来给学生一个窗口，了解古气候研究，科学家使用的方法，以及科学发现的重要性。在这里，我们提出了五个在线实验室，介绍本科生树木年代学领域。学生了解基本的树木年轮概念，并指导使用许多相同的工具和战略，科学家，包括探索重要的现场网站，测量从这些网站的树木年轮数据，使用在线古气候数据库，并评估气候趋势和极端。这些实验室已经过课堂测试，并根据专业评估以及教师和学生的评论进行了修改。教师和学生的调查和学生实验室成绩表明，大多数学生能够达到实验室的学习目标。学生们报告说，他们觉得自己像科学家一样工作，在完成实验后，他们更好地理解了树木年轮科学方法和应用。这些材料是与来自各种机构的教师投入合作开发的，具有广泛的吸引力，并允许在各种课堂环境中使用。
Abstract Scientists rely heavily on tree-ring records to better understand climate variability of the past millennium. Tree rings can also be utilized to give students a window into paleoclimate research, the methods scientists use, and the importance of scientific findings. Here, we present five online labs that introduce undergraduate students to the field of dendrochronology. Students learn about foundational tree-ring concepts and are guided to use many of the same tools and strategies as scientists, including exploring important field sites, measuring tree-ring data from those sites, using online paleoclimate databanks, and evaluating climate trends and extremes. The labs have been classroom tested and were modified based on a professional assessment, and faculty and student reviews. Faculty and student surveys and student lab grades show that the majority of students were able to meet the learning goals of the labs. Students reported that they felt they were working as scientists would, and, after completing the labs, that they better understood tree-ring science methods and applications. These materials were developed collaboratively with faculty input from a variety of institutions to have broad appeal and allow for use in a variety of classroom settings.
