The question of how to implement these effective strategies without sacrificing a significant volume of content coverage has led to the development of a “flipped” model of instruction. This flipped model requires students to take responsibility for learning some basic concepts prior to attending class so the instructor can use newly freed class time to incorporate active learning activities. This study investigated the impact of implementing a partially flipped class format on student exam performance and confidence across four semesters of a large-enrollment physical geology course. Basic geology content was presented as pre-class homework assignments using short instructional videos (Geoscience Videos) that were created following empirically-derived methods of effective multimedia design. The videos facilitated an increase in the proportion of content that could be communicated outside of class and allowed for an augmentation of in-class activities on more complex geology concepts. We compared student performance and confidence across semesters and found; (a) students were able to learn the basic content as effectively as they had when it was presented in class; (b) students improved their performance on some content during summative exams; and, (c) student confidence significantly varied on some topics as a result of the course alterations. As a result, we posit that the flipped model can provide valuable opportunities to increase student learning as long as students are supported via out-of-class homework and feedback on their level of understanding regarding topics they are learning prior to attending course meetings.}, number={3}, journal={Journal of Geoscience Education}, publisher={Informa UK Limited}, author={Jones, Jason P. and McConnell, David A. and Wiggen, Jennifer L. and Bedward, John}, year={2019}, month={Apr}, pages={195–210} } @article{steer_iverson_egger_kastens_manduca_mcconnell_2019, title={The InTeGrate Materials Development Rubric: A Framework and Process for Developing Curricular Materials that Meet Ambitious Goals}, ISBN={["978-3-030-03272-2"]}, ISSN={["2509-9795"]}, DOI={10.1007/978-3-030-03273-9_2}, abstractNote={We designed and tested a curriculum development and auditing methodology for the Interdisciplinary Teaching about Earth for a Sustainable Future (InTeGrate) project.

The ability to think on geologic timescales is regarded as an important skill in the study of geology, yet little work has specifically addressed how student understanding of this concept evolves during the undergraduate experience and beyond. We describe an exploratory, preexperimental study conducted at a large research university investigating student knowledge of various Earth history and geologic time concepts among geology majors. A 21-question pre/posttest was constructed to assess concepts related to landscape identification, landscape formation rates, Earth history, the geologic timescale, and relative and absolute dating. Pre/posttesting was conducted across four semesters within a variety of courses including historical geology, structural geology, geomorphology, and a geology field camp course. Data were also collected from a group of nonmajors in an introductory physical geology course to obtain a novice score and from a group of faculty expert geoscientists at the Geological Society of America annual meeting to obtain an expert score on the instrument. Additionally, interviews were conducted with 11 senior geology majors to gain a deeper understanding of their conceptions related to a sample of the concepts assessed. Results show that students make the largest gains after taking physical and historical geology courses, but no significant changes were seen in upper-level geology courses. Many geology students lacked familiarity with the geologic timescale and had difficulty estimating formation rates of landscapes formed on intermediate timespans.}, number={3}, journal={Journal of Geoscience Education}, publisher={Informa UK Limited}, author={Czajka, Charles Doug and McConnell, David}, year={2018}, month={Jun}, pages={231–245} } @article{chapman_mcconnell_2018, title={Characterizing the Pedagogical Beliefs of Future Geoscience Faculty Members: a Mixed Methods Study}, volume={43}, ISSN={0742-5627 1573-1758}, url={http://dx.doi.org/10.1007/S10755-017-9416-9}, DOI={10.1007/S10755-017-9416-9}, number={3}, journal={Innovative Higher Education}, publisher={Springer Nature}, author={Chapman, LeeAnna Young and McConnell, David A.}, year={2018}, month={Jun}, pages={185–200} } @article{teasdale_viskupic_bartley_mcconnell_manduca_bruckner_farthing_iverson_2017, title={A multidimensional assessment of reformed teaching practice in geoscience classrooms}, volume={13}, ISSN={["1553-040X"]}, DOI={10.1130/ges01479.1}, abstractNote={This study analyzed quantitative and qualitative data from classroom observations combined with instructor survey results to characterize the application of reformed teaching practices in undergraduate geoscience classes in the United States.

Classrooms observed included introductory and upper-level undergraduate courses that ranged in size from 6 to 275 students. Total RTOP scores do not correlate with class size, class level, institution type, instructor gender, instructor rank, or years of teaching experience. Classroom instruction was separated into three categories based on total RTOP scores: Teacher Centered (≤30), Transitional (31–49), or Student Centered (≥50). Statistical analyses of RTOP subscales and individual item scores are used to identify the instructional practices that are characteristic of each category. Instructor survey responses and qualitative classroom observations provide additional details about instructional practices common within each instructional category. Results of these analyses provide a coherent picture of instructional strategies used in geoscience classrooms. Instruction in the most Student Centered classrooms differs from that in Transitional and Teacher Centered classrooms in at least one of three ways. Student Centered classes are more likely to include (1) students engaged in class activities with one another; (2) activities in which instructors assess student learning and adjust lessons accordingly; and (3) opportunities for students to answer and pose questions that determine the focus of a lesson.}, number={2}, journal={GEOSPHERE}, author={Teasdale, Rachel and Viskupic, Karen and Bartley, Julie K. and McConnell, David and Manduca, Cathryn and Bruckner, Monica and Farthing, Dori and Iverson, Ellen}, year={2017}, month={Apr}, pages={608–627} } @article{manduca_iverson_luxenberg_macdonald_mcconnell_mogk_tewksbury_2017, title={Improving undergraduate STEM education: The efficacy of discipline-based professional development}, volume={3}, ISSN={["2375-2548"]}, DOI={10.1126/sciadv.1600193}, abstractNote={Effective teaching practices are more common in courses taught by faculty who spend time learning about teaching.}, number={2}, journal={SCIENCE ADVANCES}, author={Manduca, Cathryn A. and Iverson, Ellen R. and Luxenberg, Michael and Macdonald, R.

A kinematic model is described that assumes fold hinges were fixed, the fault propagated through the forelimb, thickness changes occurred in the forelimb, and forelimb inclination increased progressively as slip increased on the underlying fault. The model is used to examine deformation in basement-involved folds in the Bighorn Mountains and Bighorn basin. Some of the assumptions for the kinematic model were relaxed when analyzing natural folds, to account for modifications in fold geometry resulting from the distribution of secondary structures.Kinematic modeling techniques can be adapted by varying model parameters to simulate appropriate relative magnitudes of fault displacement and fault length for a specific stratigraphic section. Thus the models attempt to take account of mechanical characteristics that may show regional variations and control structural configurations. This content is PDF only.

Two structural lithic units are identified, a competent lower unit and an overlying incompetent unit. The upper unit is made up of moderate ductility rocks that were thinned ahead of the Hurt Creek fault. Offset formations in the upper unit have small relative stretch (ϵr) values and are interpreted to have represented an impediment to fault growth. In contrast, fault propagation was rapid relative to fault slip in the competent rocks of the lower structural lithic unit which have a correspondingly higher relative stretch. The Black Canyon fault is oriented at a low-angle to bedding in the lower structural lithic unit and is layer-parallel near the base of the upper unit. The Red Spring fault is a thin-skinned thrust fault and is interpreted to be linked to the Black Canyon fault to generate a triangle-zone geometry. Similar structures can be identified elsewhere in the Rocky Mountain foreland and this configuration may represent a previously unrecognized indicator of low-angle basement faults.
