In this short course, we will explore the 2025 report from the National Academies titled Transforming Undergraduate STEM Teaching. Central to the report are seven core principles that underlie effective teaching, along with recommendations for how to implement them. Our focus will be on applying these principles specifically to undergraduate STEM education in the geosciences. Through interactive discussion and practical exercises, participants will engage with the evidence behind the principles and explore how they can be translated into effective teaching strategies. By the end of the workshop, participants will be familiar with the core principles and the research supporting them, be able to describe specific teaching strategies aligned with each principle, and begin developing an action plan to implement these strategies in their geoscience courses or departmental policies and practices.

This course aims to raise awareness that sedimentary petrology and petrography have value in interpreting, assessing and predicting the resource and storage potential of porous and permeable sandstones. For decades, sandstone petrology concepts, analyses and data have been used to address questions regarding reservoir provenance, storage, and transmissibility, providing perspective other data (e.g. seismic, well log, core analysis) only indirectly provide, but recently the approach has become underutilized. Furthermore, there is a concerning deficit in the number of young geoscientists trained in and capable of characterizing sandstones at the scale of grains and pores. This course targets these issues.Basic sandstone petrology concepts of provenance, transport, deposition, compaction, and diagenesis will be presented in the context of how they control or influence lithology and reservoir properties. An emphasis on petrographic analysis of mineralogy, texture, paragenesis, and pore systems provides perspective on how rock framework and pore systems control rock properties and complement interpretation and calibration of core analyses, petrophysical logs and seismic data. Techniques to identify and quantify characteristics will be introduced and practiced. Examples combining techniques and data sets enforce benefits of integrated interpretation. Appropriate for advanced students with a working knowledge of sedimentary geology. Petrography skills not required.
