Improving Active Learning Through Advanced Teaching Practices On An Online Course, Jin Ouk O. Choi Jan 2022

Improving Active Learning Through Advanced Teaching Practices On An Online Course, Jin Ouk O. Choi

UNLV Best Teaching Practices Expo

Since the outbreak of the COVID, there has been a great need to advance learning experiences and opportunities for students when the courses are taught remotely. To address the need, the author incorporated the teaching strategies learned from the Culturally Relevant & Responsive Teaching (CRRT) fellows program supported by the NSF TRANSCEnD project. In Fall 2021, the author implemented multiple new teaching techniques and strategies in the CEM453-653 course, delivered entirely online. The specific teaching practices and technologies are: 1) Delivering lectures both live (synchronous) and recordings (asynchronous); 2) Using adaptive technology (Mentimeter & WebEx Poll) with real-time feedback; 3) …


Collective Risk Of Construction Development On Desert Tortoise Populations, Paulina Smith Apr 2021

Collective Risk Of Construction Development On Desert Tortoise Populations, Paulina Smith

Undergraduate Research Symposium Posters

Desert tortoises (Gopherus agassizii) are threatened, extremely territorial reptiles living on a rapidly-shrinking landscape. This literature review was conducted with the goal of determining whether the desert tortoises of the Mojave Desert are experiencing compounded effects from construction development which are not reflected in mortality/fecundity calculations in the current literature. Seventeen peer-reviewed sources were identified from the last 20 years which related to roads, railroads, wind-harvesting, solar energy, and man-made barriers/flood control centers in the Mojave. Current literature reveals that researchers do not have the time nor resources to pursue long-term studies on all of the possible effects on this …


The Effect Of Lanthanides On Corn Growth, Savanna Vacek Apr 2021

The Effect Of Lanthanides On Corn Growth, Savanna Vacek

Undergraduate Research Symposium Podium Presentations

Wastewater treatment plants (WWTPs) offer a reliable source of reclaimed water for irrigation. Metal-based chemicals (i.e. coagulants) are frequently employed in wastewater treatment, and residual metal ions remain in the treated wastewater, which could result in application of these metal ions to agricultural fields and crops. This study focuses on an emerging coagulant containing lanthanum. The behavior of lanthanum reclaimed water (LaRW) towards corn growth is barely known. Thus, if we are to recycle LaRW to support corn growth, the effects of LaRW on corn growth need to be studied. Corn kernels were grown in varying lanthanum concentrations (0-5000 mg …
