Within this population, ELL students in Indiana number over 50,000, or 5.9% of all public K–12 students in the state. Dual- language bilingual education (DLBE) programs oft en neglect the strategy of translanguaging in the classroom, disadvantaging ELLs. Translanguaging is defi ned as drawing “on all the linguistic resources of the child to maximize understanding and achievement” and is demonstrated in the natural switching of languages in bilinguals (Lewis et al., 2012). Further, translanguaging attempts to correct past English- only ideals for the equity of ELL students. Th is case study aims to answer two questions: (1) What are the translanguaging views and practices of elementary school teachers in DLBE classrooms? (2) Are there diff erences in translanguaging views and practices between bilingual native Spanish speakers, bilingual native English speakers, and nonbilingual native English speakers? Data was collected from the course data of seven elementary school teachers who are part of DLBE programs in two schools in Indiana to better determine the correlation between DLBE teachers’ linguistic backgrounds and their views and practices of translanguaging in their classrooms. Results found a connection between teachers’ own bilingualism and an increased use of translanguaging practices in their classrooms, which can help off set decades of inequity between English language learning students and their monolingual peers.","PeriodicalId":30386,"journal":{"name":"Journal of Purdue Undergraduate Research","volume":"130 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90705233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite national strides toward equality, women are still vastly unrepresented in STEM-based fields—and not for lack of merit. Lisa Darragh (“Identity research in mathematics education.” Educational Studies in Mathematics, 2016, doi.org/10.1007/s10649-016-9696-5) defines identity as the performance and recognition of one’s self and the individual’s larger role in society and social contexts. In 1994 Laura Jones was disheartened to hear her daughter describe herself as “not good at math,” despite overwhelming evidence to the contrary. Laura started an afterschool club, Girls Excelling in Math and Science (GEMS), to bolster confidence in young women who were self-selecting out of STEM classes. Survey responses, focus group interviews, and individual interviews were conducted with the original members of the first GEMS club. I considered responses from an original member, Amanda, using thematic analysis to identify and categorize references to herself and to her role in society. Given this, we were able to study how Amanda’s identity changed before, during, and after her participation in GEMS. When reflecting on her time prior to her involvement in GEMS, Amanda was self-critical, choosing to note that “I struggled a lot with science when I was in high school—I remember that very clearly. I was not very good.” However, a shift was identified when she described herself in the present, where she notes that “I manage people . . . like the boss, basically.” Given our findings from Amanda’s data, GEMS seems to be a context where girls develop their identity.","PeriodicalId":30386,"journal":{"name":"Journal of Purdue Undergraduate Research","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82635421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experience Doesn't Matter, but the Direction Does 经验不重要，方向重要

As people gain intuition and understanding of physics through observing and interacting with their surroundings, one might expect that this disconnect would disappear. However, many students have extensive experiences where they behave correctly yet continue to construct incorrect explanations. In this study, 53 non-STEM undergraduate students enrolled in a physics course that had yet to cover the topic of relative motion were given a survey of common relative motion physics problems. The problems differed in the direction an object is thrown—either vertically or horizontally—and the frame of reference in which the reader is placed. The questions then involved subjects who were either stationary or moving, such as being on a skateboard or a bus. We found that the direction of the throw relative to the motion of the person (i.e., vertical or horizontal) and the reference frame in which the reader is placed affected the accuracy of student responses. This may be due to participants using different embodied experiences when imagining throwing a ball vertically to oneself than when throwing an object horizontally to another person, meaning that reenacting physical scenarios might provide a small benefit for more embodied tasks such as tossing a ball in a moving bus. Considering these results, future research should investigate students’ reasoning when completing relative motion problems that differ in direction and reference frame to fully understand the nature of the disconnect.","PeriodicalId":30386,"journal":{"name":"Journal of Purdue Undergraduate Research","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75291493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Manganese exposure may result in Parkinson-like symptoms. It has been hypothesized that altered iron concentrations in the brain could also lead to neurological symptoms similar to what appears in those with chronic exposer to manganese. Th erefore, the goal of this project is to explore the relationship between manganese and hepcidin as an indicator of altered iron homeostasis. Population demographics were collected from semi-trailer factory workers in a cross-sectional study via a questionnaire. Demographic information includes age, race, and weight. Toenail clippings and questionnaires were collected on the same day; blood and air concentrations were sampled on a diff erent day within a short time period. Statistical analyses include descriptive statistics and regression analyses. Multiple linear regressions were run that utilized hepcidin and transferrin as dependent variables, with air, toenail, and blood manganese and welder status as independent variables. Mean air concentrations for the metals were below recommended exposure limits. Manganese toenail concentrations were 5.23 μg/g (standard deviation [SD] = 2.53 μg/g) while iron toenail concentrations were 183.93 μg/g (SD = 124.06 μg/g). Results showed a statistically signifi cant association between natural log (ln)(hepcidin) and welding status (p = 0.042); no statistically signifi cant relationship was found between ln(hepcidin) with air manganese (p = 0.313) or toenail manganese (p = 0.672). Th ere was no association found between transferrin and air manganese, toenail manganese, or welder status. Continued research is needed to investigate these relationships further.","PeriodicalId":30386,"journal":{"name":"Journal of Purdue Undergraduate Research","volume":"94 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75640439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
