在地球科学界有一个明确的愿望,让学生在实地工作的方式,最大限度地减少机构(成本,规模,责任)和环境障碍(家庭义务,经济负担),减少实地考察参与入门级。在这里,我们证明了非专业的学生想要获得实地考察的经验,然而,对时间和交通的关注限制了学生在课外时间进行实地考察的能力,即使提供。我们使用免费的NSF资助的Flyover Country移动的应用程序来创建自助实地考察,前往具有地质特征的地区公园和城市地区。这些旅行是在一个小的,非主要的重点,地质学导论课程,以前经历了上课时间以外的实地考察出席率低。然后,我们将学生使用该应用程序的体验与参加传统导游带领的旅行的同一课程的学生的体验进行了比较。实验室成绩和学生的调查结果提供的证据表明,学生在自我指导的实地考察观察到类似的地质和报告类似的情感结果作为那些学生谁参加了导游带领的旅行。虽然在入门级的结果表明,自我指导的方式是一个有前途的选择,结果可能会有所不同,为更多的技术上师课程。
There is a clear desire in the geoscience community to engage students in field work in ways that minimize institutional (cost, size, liability) and circumstantial barriers (family obligations, financial burdens) that decrease field trip participation at the introductory level. Here we demonstrate that non-major students want accessible field experiences; however, concerns over time and transportation limit students’ ability to engage in field trips outside of class time, even when offered. We used the free NSF-funded Flyover Country mobile app to create self-guided field trips to regional parks and urban areas with geological features of interest. These trips were implemented in a small, non-major focused, Introduction to Geology course which had previously experienced poor attendance for field trips outside of class time. We then compared experiences of students using the app to experiences of students in the same course who attended a traditional instructor-led trip. Lab grades and student survey responses provide evidence that students on the self-guided field trips observed similar geology and reported similar affective outcomes as those students who attended the instructor-led trip. While outcomes at the Introductory level suggest a self-guided modality is a promising option, results may vary for more technical upper division courses.
