A Transformative Approach to Incorporating Adaptive Courseware: Strategic Implementation, Backward Design and Research-based Teaching Practices

In July 2016, Colorado State University (CSU) joined seven other land-grant institutions in the Accelerating Adoption of Adaptive Courseware grant sponsored by the Personalized Learning Consortium (PLC) of the Association of Public and Land-grant Universities (APLU). A primary objective of the grant was to scale the adoption of adaptive courseware in general education courses at each of the grant institutions. CSU targeted high-enrollment, general education courses and took a three-pronged, transformative approach to the integration of adaptive courseware. Specifically, CSU divided the courseware integration into three components: 1) strategic implementation of courseware, 2) backward course design, and 3) incorporation of research-based teaching practices. By May 2020, it is projected that over 40,000 students will have taken courses that were developed in this manner. Faculty participating in the grant completed the Teaching Practices Inventory (TPI) developed by the Wieman Institute. The inventory measures the extent to which instructors use research-based teaching practices (ETP). Faculty use of research-based teaching practices in strategic alignment with active learning and adaptive courseware provided the greatest measure of success. In general, instructors with ETP scores above 24 had higher course success rates than those with lower ETP scores. However, these differences were statistically significant for instructors of STEM courses with ETP scores of 30 and higher. Data indicates that simply adding adaptive courseware is not enough to impact student success. It is the combination of: 1) strategic implementation of courseware, 2) backward course design, and 3) the incorporation of research-based teaching practices that has the most potential to impact student success

Swim Instructor Beliefs About Toddler and Pre-School Swimming and Water Safety Education

To study the teacher component of the parent-teacher-learner triad in preschool aquatics and explore compatibility of instructor messages with current drowning prevention beliefs, 133 preschool aquatics instructors were surveyed. Instructors with basic swim teacher accreditation and those with a preschool/infant instructor extension (“Extension”) were compared. More Extension instructors selected “safety” as an important outcome (χ2 = 7.907, df = 3, p = 0.048). Both instructor groups considered parental education important but Extension instructors held this view more strongly. Disturbingly, more Extension instructors disagreed that increased toddler confidence following lessons necessitates greater supervision around water (χ2 = 4.141, df = 1, p = 0.042). To avoid such messages, instructor education should place even greater emphasis on close and constant adult supervision and counter the misconception that early age lessons protect children from drowning

Avian Hosts for West Nile Virus in St. Tammany Parish, Louisiana, 2002

West Nile virus (WNV) infections in free-ranging birds were studied in Slidell, St. Tammany Parish, Louisiana, after a human encephalitis outbreak peaked there in July 2002. Seroprevalence in resident, free-ranging wild birds in one suburban site was 25% and 24% in August and October, respectively, indicating that most transmission had ceased by early August. Mortality rates, seroprevalence rates, host competence, and crude population estimates were used in mathematical models to predict actual infection rates, population impacts, and importance as amplifying hosts for several common passerine birds. Northern cardinal (Cardinalis cardinalis) and house sparrow (Passer domesticus) were the principal amplifying hosts, but blue jay (Cyanocitta cristata) and northern mockingbird (Mimus polyglottos) also contributed. The blue jay population was reduced by an estimated 47%. A variety of passerine bird species combined to play an important role as amplifying hosts in the WNV transmission cycle

Nutrient enrichment induces dormancy and decreases diversity of active bacteria in salt marsh sediments

The definitive version was published in Nature Communications 7 (2016): 12881, doi:10.1038/ncomms12881.Microorganisms control key biogeochemical pathways, thus changes in microbial diversity, community structure and activity can affect ecosystem response to environmental drivers. Understanding factors that control the proportion of active microbes in the environment and how they vary when perturbed is critical to anticipating ecosystem response to global change. Increasing supplies of anthropogenic nitrogen to ecosystems globally makes it imperative that we understand how nutrient supply alters active microbial communities. Here we show that nitrogen additions to salt marshes cause a shift in the active microbial community despite no change in the total community. The active community shift causes the proportion of dormant microbial taxa to double, from 45 to 90%, and induces diversity loss in the active portion of the community. Our results suggest that perturbations to salt marshes can drastically alter active microbial communities, however these communities may remain resilient by protecting total diversity through increased dormancy

Myeloperoxidase-mediated Protein Lysine Oxidation Generates 2- aminoadipic acid and Lysine nitrile in vivo

Recent studies reveal 2-aminoadipic acid (2-AAA) is both elevated in subjects at risk for diabetes and mechanistically linked to glucose homeostasis. Prior studies also suggest enrichment of protein-bound 2-AAA as an oxidative post-translational modification of lysyl residues in tissues associated with degenerative diseases of aging. While in vitro studies suggest redox active transition metals or myeloperoxidase (MPO) generated hypochlorous acid (HOCl) may produce protein-bound 2-AAA, the mechanism(s) responsible for generation of 2- AAA during inflammatory diseases are unknown. In initial studies we observed that traditional acid- or basecatalyzed protein hydrolysis methods previously employed to measure tissue 2-AAA can artificially generate protein-bound 2-AAA from an alternative potential lysine oxidative product, lysine nitrile (LysCN). Using a validated protease-based digestion method coupled with stable isotope dilution LC/MS/MS, we now report protein bound 2-AAA and LysCN are both formed by hypochlorous acid (HOCl) and the MPO/H2O2/Cl− system of leukocytes. At low molar ratio of oxidant to target protein Nε-lysine moiety, 2-AAA is formed via an initial Nε- monochloramine intermediate, which ultimately produces the more stable 2-AAA end-product via sequential generation of transient imine and semialdehyde intermediates. At higher oxidant to target protein Nε-lysine amine ratios, protein-bound LysCN is formed via initial generation of a lysine Nε-dichloramine intermediate. In studies employing MPO knockout mice and an acute inflammation model, we show that both free and proteinbound 2-AAA, and in lower yield, protein-bound LysCN, are formed by MPO in vivo during inflammation. Finally, both 2-AAA and to lesser extent LysCN are shown to be enriched in human aortic atherosclerotic plaque, a tissue known to harbor multiple MPO-catalyzed protein oxidation products. Collectively, these results show that MPO-mediated oxidation of protein lysyl residues serves as a mechanism for producing 2-AAA and LysCN in vivo. These studies further support involvement of MPO-catalyzed oxidative processes in both the development of atherosclerosis and diabetes risk
