Abstract:

Critical thinking is foundational for environmental geologists confronting complex, multidisciplinary challenges such as climate change, sustainability, resource management, engineering geology, and environmental remediation. Yet, fostering this skill in online graduate programs requires innovative pedagogical strategies to overcome constraints like limited direct fieldwork, technology variability, asynchronous learning environments, and student isolation. To address these comprehensively, we employed the MOSAIC framework (Modular, Outcome-based, Stackable, Adaptive, Integrated Curriculum), transforming our online graduate environmental geology program into a dynamic digital learning ecology.

Our MOSAIC approach treats the curriculum as an interconnected ecosystem rather than isolated courses, enabling learners to engage critically, creatively, and collaboratively in authentic, context-driven problems mirroring professional practice. Core design elements include modular course structures allowing personalized yet integrated learning paths, authentic tasks utilizing diverse datasets, and interactive virtual experiences simulating professional geoscience contexts like environmental and engineering geology assessments and hazard mitigation planning.

Central to our MOSAIC-based ecology is the intentional integration of environmental professionals actively working in consulting roles, serving as mentors, guest speakers, and facilitators of networking. This professional network significantly enhances peer-to-peer mentoring, collaboration, and networking opportunities. Direct interactions with seasoned professionals provide learners valuable insights into industry practices and create robust synergies for capstone projects. These experiences frequently evolve into professionally relevant endeavors, benefiting from the enriched professional network and enabling students to seamlessly bridge academic theory with industry practice.

Learners develop robust critical thinking skills by systematically analyzing complex environmental scenarios, proposing viable remediation strategies, and deeply reflecting on their decision-making through structured discussions, reflective journaling, and collaborative virtual team projects. Ongoing feedback loops and iterative assignments help learners progressively refine analytical approaches and reasoning skills.

Reflective outcomes highlight how cultivating digital ecologies through MOSAIC significantly enhances critical inquiry, learner autonomy, and engagement, enriching the online learning environment. Students master theoretical and practical content while acquiring transferable skills in interdisciplinary problem-solving, information synthesis, effective communication, and evidence-based decision-making. Structured community interactions, mentoring components, and consistent formative assessments reinforce cognitive presence, establishing a vibrant scholarly network, a culture of continual reflection, and preparing graduates for professional success.

This exploration underscores how thoughtfully designed online educational ecosystems effectively cultivate advanced critical thinking, seamlessly bridging theoretical concepts with professional practice in environmental and engineering geology.
