This Work-in-Progress research paper focuses on the game-based learning environment of GeoExplorer, a digital learning tool that simulates Cone Penetration Testing (CPT) – a field test that civil engineers conduct to understand soil properties. This paper aims to investigate the gendered patterns of student interaction with GeoExplorer, if any, and the associated gendered patterns of content comprehension and self-efficacy related to one's ability to pursue CPT in the field, if any. As such, we ask: (1) How, if at all, does gender affect a student's belief in their ability to apply skills gained through engagement with GeoExplorer in real world environments? and (2) How, if at all, do prior gaming experience and gender impact the GeoExplorer play experience? Four open-ended semi-structured interviews regarding students' experience with gameplay, gender identity, and learning were analyzed. Preliminary analyses used narrative and grounded theory approaches. Our early findings indicate a lack of student insight on the role of their gender identity on their gameplay experience and the presence of a gendered impact of gameplay on student learning and self-efficacy in carrying out CPT in the field. 

Retaining structures in waterfront areas are sensitive to seismically triggered liquefaction, leading to large deformations of the backfill and the retaining structure. The response of such systems depends heavily on the soil parameters, one of the most important being its relative density. This paper summarizes the key aspects of three centrifuge experiments performed at the Center for Earthquake Engineering Simulation (CEES) at Rensselaer Polytechnic Institute in 2020 as part of the experimental campaign for the Liquefaction Experiments and Analysis Project (LEAP-2020). The three models reflected the same prototype problem of a rigid floating sheet-pile quay wall supporting a 3-m-deep liquefiable soil deposit, of loose, medium dense and dense soil relative densities. The three models observed the same building technique and were subjected to the same target dynamic input motion. 

The LEAP (Liquefaction Experiment and Analysis Project) is a continuing international collaboration to create a reliable databank of high-quality experimental results for the validation of numerical tools. This paper investigates the response of a floating rigid sheet-pile quay wall under conditions of seismically induced liquefaction, embedded in dense sand and supporting a saturated liquefiable soil deposit. The experimental challenges related to repeatability in physical modeling in such a soil-structure-interaction regime are also discussed. To this end, three experiments performed at Rensselaer Polytechnic Institute (RPI) as part of the experimental campaign for the LEAP-2020 are discussed herein. Models RPI_REP-2020 and RPI10-2020 investigate the repeatability potential in centrifuge modeling in the presence of soil-structure-interaction. Model RPI_P-2020 is the pilot test of the LEAP-2020 experimental campaign at RPI and investigates the effect of the wall’s initial orientation on the system’s dynamic response and soil liquefaction, as a possible “defect” in the model construction procedure. The three models were built in a consistent way, employed comparable instrumentation layout while simulating the same prototype and comparable soil conditions. The three models were subjected to the same acceleration target input motion, which was repeated across all three models with high consistency.
