The research described in this case study features a cohort of five exchange students from post-secondary institutions in Norway and the United States who collaboratively engaged in a project-based learning experience infused with aspects of place-based education, lesson study, and the pedagogical technique “students as partners”. The students were tasked with crafting an interdisciplinary lesson combining mathematics and environmental science to address a localized problem in the Southeastern United States. This study reflects on how the students participated in project-based learning as well as the instructional practices that supported student engagement. Students identified an increase in understanding of interdisciplinary and multicultural Science, Technology, Engineering, and Mathematics (STEM) education, a broader understanding of instructional practices, and exposure to educational research. Data were collected throughout the study using a variety of techniques, including discussion posts, collaborative documents, and reflections to gauge student experience and project progress. The results provide evidence to support the use of project-based learning in postsecondary STEM classrooms and emphasize the benefits of engaging students in curriculum development.

It is uncommon for large service courses in geology to provide engaging outdoor activities that effectively mimic the experiences of working geologists, despite the fact that field experiences are a well-established pathway for recruiting students to the geosciences. We address this problem by creating extra credit activities that are integrated and implemented within a geocaching framework to provide students with these outdoor, extracurricular learning experiences. Three extra credit implementation strategies were devised for each of three geology service courses. Students from two small and one large geology course independently completed geology lessons at each geocaching site via a Google Forms platform. Across 757 activities completed during the Fall 2016 semester, more than two-thirds of evaluations reported that the student enjoyed the activity and learned something, and almost half of evaluations indicated the student wanted to learn more about the topic. Participation rates were highest in students who were high achievers, women, and freshmen and sophomores, but did not vary much with respect to ethnicity, major, or traditional/contemporary student status. Designing a successful implementation strategy at other institutions is likely dependent on course goals and class size.

Recruitment and retention are critical for geoscience and the need for innovative ways of building these bridges to the geosciences is growing. Field experiences are a common attractor for students to the field sciences such as geoscience, but many research- and field-based experiences are limited to those who are already majors. Innovative, experiential approaches to geoscience recruitment and retention could be a new way to attract more students to geoscience. International field and research experiences designed for undergraduates from any academic discipline aim to provide opportunities for students to explore their (geo)science interests and potential career paths. A single, exploratory case study approach with semi-structured interviews combined with quantitative pre- and post-survey results is used to highlight the experiences of four students and their plans for continuing in the geosciences. Students (including geoscience and non-geoscience majors) were found to have had inherent, pre-college, and college influences for participation in the field experience; all students indicated plans to continue in the geosciences. Two years after the experience, researchers followed-up with the students and found that three of the four were still involved in the geosciences. Many international geoscience field experiences are exclusively for majors, but experiential learning opportunities like these should also be considered for potential majors. These results are beneficial for departments interested in designing and adapting their recruitment and retention efforts to better train the next generation of geoscientists.
