Improving Student Engagement in Nursing Education through Game-Based Learning

Educators have identified that engaging nursing students in their education increase retention rates in nursing education programs. As a pedagogical tool, using game-based learning activities allowed educators to create student-centered active learning opportunities to increase the engagement of the nursing student. The problem was that the effect of adding game-based learning to traditional lectures on student engagement behaviors in undergraduate nursing classes was unknown. The purpose of this mixed-methods study was to examine how adding game-based learning to traditional lectures affected student engagement behaviors in undergraduate nursing classes. The theoretical framework was based on the theory of Constructivism, which is the concept that students are lifelong learners who prefer to take an active role in their education. The research questions for this study explored the relationship and effect of adding game-based learning activities to traditional teaching methods and an improved student engagement level in nursing students. A Pearson Correlation Coefficient test was performed to monitor the correlation between the addition of game-based learning and improved student engagement for the quantitative section of this study. For the qualitative portion, in-person interviews were conducted with the participants, and a codebook was created to identify themes for final analysis. A convenience sample was used to recruit participants in a Bachelor of Nursing undergraduate entry level nursing course, resulting in 47 out of 72 students agreeing to participate. Quantitative findings from the study revealed that there was a minimal correlation between adding game-based learning activities to traditional teaching methods and improved engagement in nursing students. The qualitative analysis discovered that students preferred game-based activities. The participants found that the combination of both game-based activities and traditional teaching methods increased their enjoyment of the course and improved their engagement. The quantitative analysis did not find a strong relationship between adding game-based learning activities and increased student engagement. The findings suggested that student engagement in nursing education improved when game-based learning was combined with traditional teaching methods. This finding can potentially improve nursing education by providing educators with another pedagogical method to create a more active learning environment for nursing students to improve their engagement.

Factors Affecting NCLEX-RN Success in an Associate Degree Nursing Program

An acute nursing shortage currently exists in the United States. It is important for nursing programs to prepare nursing students who are able to pass the NCLEX-RN. The purpose of this study was to determine whether a link exists between nursing student performance in program requirements and ultimate success or failure on the NCLEX-RN. A random sample of the nursing students at one community college who graduated in the calendar years of 2017 and 2018 were the population for this study. This comparative study examined data in existence to determine if there were academic factors relating to failure on NCLEX-RN. Chi-square was used to determine a relationship and phi-coefficient was used to determine the strength of that relationship between dependent and independent variables. A weak to moderate association was found between failure on NCLEX-RN and the independent variables: low score on the science portion of the TEAS test, need to repeat the first medical-surgical nursing course, and less than 850 on HESI exit. Future research should focus on the connection between mathematics scores and success in the nursing program and NCLEX-RN.

Embracing Common Core Standards for Mathematical in Secondary Mathematical Practice

Teachers' support in implementing the standards for mathematical practice has been an area of study since the implementation of the Common Core state standards initiative. The research problem had a gap in the literature regarding what teachers perceive as the supports needed to implement the Common Core standards for mathematical practice in the classroom. The Common Core initiative's standardized educational reform goal is to better prepare students for career and college readiness in the United States. Fidelity in implementation is essential to the success of the reform. The purpose of this qualitative research was to explore what teachers perceive as the supports needed to implement the Common Core standards for mathematical practice in the classroom. Twelve middle school mathematics teachers participated in semistructured interviews to provide data on their use of the standards and their perception of support needs. The conceptual framework of this study was the interconnected model of professional growth. The results of the study indicated a reported gap in practice regarding the use of the standards from the teachers’ account. They further identified the need for formal training to understand better and use the standards. The support teachers seek is to have training that can allow them to learn more about the purpose of the standards and training that can be adapted to their needs based on their current practices and experiences. The research findings can help with the fidelity of implementation, and possibly influence social change by assisting teachers in using best practices to prepare students for college and career readiness in mathematics.

Campus Climate Experiences Associated with Ethnicity in a College of Health Sciences

The demand for various healthcare professionals is expected to increase along with the diversification of patient populations. Job security is promising in the future of healthcare. Still, less than 50% of college students persist through the STEM education necessary for professional degree programs, with higher attrition rates seen with minority students. The problem is the disproportionate ethnic representation in academic programs that precipitates the consequentially low distribution of minorities in clinical practice and higher education. Inadequate representation poses fewer opportunities for an initial sense of similarity for minority students, often needed for motivation during student-to-faculty interactions. The research study measured differences between ethnic minority and non-minority student perceptions of their academic climate through a quasi-experimental quantitative design. The dependent variables included a sense of belonging, academic and interpersonal validation. Likert scale data was collected to analyze total summed scores between participant groups. Question items from the Diverse Learning Environment Survey were extracted and used as the instrument. The participant group consisted of students from a Division II institution enrolled in an anatomy and physiology course. Data analysis consisted of independent t-tests and Mann Whitney-U testing. Statistically significant differences were found in the sense of belongingness between groups, with ethnic minority students scoring significantly lower. This study's findings help inform educators and clinicians about the needs of minority populations in efforts to retain students and diversify the same force that is assumed to be all-inclusive in clinical practice.

Ocean Acidification Has Multiple Modes of Action on Bivalve Larvae

Ocean acidification (OA) is altering the chemistry of the world’s oceans at rates unparalleled in the past roughly 1 million years. Understanding the impacts of this rapid change in baseline carbonate chemistry on marine organisms needs a precise, mechanistic understanding of physiological responses to carbonate chemistry. Recent experimental work has shown shell development and growth in some bivalve larvae, have direct sensitivities to calcium carbonate saturation state that is not modulated through organismal acid-base chemistry. To understand different modes of action of OA on bivalve larvae, we experimentally tested how pH, P[subscript]CO2, and saturation state independently affect shell growth and development, respiration rate, and initiation of feeding in Mytilus californianus embryos and larvae. We found, as documented in other bivalve larvae, that shell development and growth were affected by aragonite saturation state, and not by pH or P[subscript]CO2. Respiration rate was elevated under very low pH (~7.4) with no change between pH of ~ 8.3 to ~7.8. Initiation of feeding appeared to be most sensitive to P[subscript]CO2, and possibly minor response to pH under elevated P[subscript]CO2. Although different components of physiology responded to different carbonate system variables, the inability to normally develop a shell due to lower saturation state precludes pH or P[subscript]CO2 effects later in the life history. However, saturation state effects during early shell development will carry-over to later stages, where pH or P[subscript]CO2 effects can compound OA effects on bivalve larvae. Our findings suggest OA may be a multi-stressor unto itself. Shell development and growth of the native mussel, M. californianus, was indistinguishable from the Mediterranean mussel, Mytilus galloprovincialis, collected from the southern U.S. Pacific coast, an area not subjected to seasonal upwelling. The concordance in responses suggests a fundamental OA bottleneck during development of the first shell material affected only by saturation state

Validating AU Microscopii d with Transit Timing Variations

AU Mic is a young (22 Myr), nearby exoplanetary system that exhibits excess transit timing variations (TTVs) that cannot be accounted for by the two known transiting planets nor stellar activity. We present the statistical “validation” of the tentative planet AU Mic d (even though there are examples of “confirmed” planets with ambiguous orbital periods). We add 18 new transits and nine midpoint times in an updated TTV analysis to prior work. We perform the joint modeling of transit light curves using EXOFASTv2 and extract the transit midpoint times. Next, we construct an O − C diagram and use Exo-Striker to model the TTVs. We generate TTV log-likelihood periodograms to explore possible solutions for d’s period, then follow those up with detailed TTV and radial velocity Markov Chain Monte Carlo modeling and stability tests. We find several candidate periods for AU Mic d, all of which are near resonances with AU Mic b and c of varying order. Based on our model comparisons, the most-favored orbital period of AU Mic d is 12.73596 ± 0.00793 days ( T _C _,d = 2458340.55781 ± 0.11641 BJD), which puts the three planets near 4:6:9 mean-motion resonance. The mass for d is 1.053 ± 0.511 M _⊕ , making this planet Earth-like in mass. If confirmed, AU Mic d would be the first known Earth-mass planet orbiting a young star and would provide a valuable opportunity in probing a young terrestrial planet’s atmosphere. Additional TTV observations of the AU Mic system are needed to further constrain the planetary masses, search for possible transits of AU Mic d, and detect possible additional planets beyond AU Mic c

The Magellan-TESS Survey I: Survey Description and Mid-Survey Results

One of the most significant revelations from Kepler is that roughly one-third of Sun-like stars host planets which orbit their stars within 100 days and are between the size of Earth and Neptune. How do these super-Earth and sub-Neptune planets form, what are they made of, and do they represent a continuous population or naturally divide into separate groups? Measuring their masses and thus bulk densities can help address these questions of their origin and composition. To that end, we began the Magellan-TESS Survey (MTS), which uses Magellan II/PFS to obtain radial velocity (RV) masses of 30 transiting exoplanets discovered by TESS and develops an analysis framework that connects observed planet distributions to underlying populations. In the past, RV measurements of small planets have been challenging to obtain due to the faintness and low RV semi-amplitudes of most Kepler systems, and challenging to interpret due to the potential biases in the existing ensemble of small planet masses from non-algorithmic decisions for target selection and observation plans. The MTS attempts to minimize these biases by focusing on bright TESS targets and employing a quantitative selection function and multi-year observing strategy. In this paper, we (1) describe the motivation and survey strategy behind the MTS, (2) present our first catalog of planet mass and density constraints for 25 TESS Objects of Interest (TOIs; 20 in our population analysis sample, five that are members of the same systems), and (3) employ a hierarchical Bayesian model to produce preliminary constraints on the mass-radius (M-R) relation. We find qualitative agreement with prior mass-radius relations but some quantitative differences (abridged). The the results of this work can inform more detailed studies of individual systems and offer a framework that can be applied to future RV surveys with the goal of population inferences.Comment: 101 pages (39 of main text and references, the rest an appendix of figures and tables).

A planet within the debris disk around the pre-main-sequence star AU Microscopii

AU Microscopii (AU Mic) is the second closest pre main sequence star, at a distance of 9.79 parsecs and with an age of 22 million years. AU Mic possesses a relatively rare and spatially resolved3 edge-on debris disk extending from about 35 to 210 astronomical units from the star, and with clumps exhibiting non-Keplerian motion. Detection of newly formed planets around such a star is challenged by the presence of spots, plage, flares and other manifestations of magnetic activity on the star. Here we report observations of a planet transiting AU Mic. The transiting planet, AU Mic b, has an orbital period of 8.46 days, an orbital distance of 0.07 astronomical units, a radius of 0.4 Jupiter radii, and a mass of less than 0.18 Jupiter masses at 3 sigma confidence. Our observations of a planet co-existing with a debris disk offer the opportunity to test the predictions of current models of planet formation and evolution.Comment: Nature, published June 24th [author spelling name fix

The First Post-Kepler Brightness Dips of KIC 8462852

We present a photometric detection of the first brightness dips of the unique variable star KIC 8462852 since the end of the Kepler space mission in 2013 May. Our regular photometric surveillance started in October 2015, and a sequence of dipping began in 2017 May continuing on through the end of 2017, when the star was no longer visible from Earth. We distinguish four main 1-2.5% dips, named "Elsie," "Celeste," "Skara Brae," and "Angkor", which persist on timescales from several days to weeks. Our main results so far are: (i) there are no apparent changes of the stellar spectrum or polarization during the dips; (ii) the multiband photometry of the dips shows differential reddening favoring non-grey extinction. Therefore, our data are inconsistent with dip models that invoke optically thick material, but rather they are in-line with predictions for an occulter consisting primarily of ordinary dust, where much of the material must be optically thin with a size scale <<1um, and may also be consistent with models invoking variations intrinsic to the stellar photosphere. Notably, our data do not place constraints on the color of the longer-term "secular" dimming, which may be caused by independent processes, or probe different regimes of a single process

Genomics, Exometabolomics, and Metabolic Probing Reveal Conserved Proteolytic Metabolism of Thermoflexus hugenholtzii and Three Candidate Species From China and Japan

Thermoflexus hugenholtzii JAD2 , the only cultured representative of the Chloroflexota order Thermoflexales, is abundant in Great Boiling Spring (GBS), NV, United States, and close relatives inhabit geothermal systems globally. However, no defined medium exists for T. hugenholtzii JAD2 and no single carbon source is known to support its growth, leaving key knowledge gaps in its metabolism and nutritional needs. Here, we report comparative genomic analysis of the draft genome of T. hugenholtzii JAD2 and eight closely related metagenome-assembled genomes (MAGs) from geothermal sites in China, Japan, and the United States, representing “Candidatus Thermoflexus japonica,” “Candidatus Thermoflexus tengchongensis,” and “Candidatus Thermoflexus sinensis.” Genomics was integrated with targeted exometabolomics and C metabolic probing of T. hugenholtzii. The Thermoflexus genomes each code for complete central carbon metabolic pathways and an unusually high abundance and diversity of peptidases, particularly Metallo- and Serine peptidase families, along with ABC transporters for peptides and some amino acids. The T. hugenholtzii JAD2 exometabolome provided evidence of extracellular proteolytic activity based on the accumulation of free amino acids. However, several neutral and polar amino acids appear not to be utilized, based on their accumulation in the medium and the lack of annotated transporters. Adenine and adenosine were scavenged, and thymine and nicotinic acid were released, suggesting interdependency with other organisms in situ. Metabolic probing of T. hugenholtzii JAD2 using C-labeled compounds provided evidence of oxidation of glucose, pyruvate, cysteine, and citrate, and functioning glycolytic, tricarboxylic acid (TCA), and oxidative pentose-phosphate pathways (PPPs). However, differential use of position-specific C-labeled compounds showed that glycolysis and the TCA cycle were uncoupled. Thus, despite the high abundance of Thermoflexus in sediments of some geothermal systems, they appear to be highly focused on chemoorganotrophy, particularly protein degradation, and may interact extensively with other microorganisms in situ.
