Method: One-hundred and four typically developing children, 48 HSs and 58 monolingual, were selected based on two age groups (Preschool vs. 3rd Grade). Two comprehension and three production experimental tasks were designed for the three different grammatical structures where Spanish expresses gender (determiners, adjectives, and clitic pronouns). Linear mixed-models were used to examine main effects between groups and grammatical structures.
Results: Results from this study showed that HSs scored significantly lower than monolingual speakers in all tasks and structures; however, 3rd-Grade HSs had higher accuracy than PK-HSs. Error patterns were similar between monolinguals and HSs. Moreover, the commonly reported overgeneralization of the masculine form seems to decrease as HSs get older.
Conclusion: These results suggest that HSs’ do not face a case of Incomplete Acquisition or Restructured Grammatical gender system, but instead follow a protracted language development in which grammatical skills continue to develop after preschool years and follow the same developmental patterns as monolingual children
Method: Fifty-six participants in 2nd-5th grade were randomly assigned to one of two groups: 1) Spanish-support intervention, or 2) Spanish-support control. Outcome measures included performance on comprehension questions related to intervention texts, questions on the final narrative and expository text without strategy instruction, and difference scores on alternate forms of the Gates-MacGinitie (GMRT-4, MacGinitie, MacGinitie, Maria, & Dreyer, 2002) reading comprehension subtest administered pre- post-intervention. Multi-level hierarchical linear models were used to account for nesting of question within child within classroom. Regression models were used to examine the power of motor predictors in predicting Spanish and English language performance.
Results: Results from study 1 indicated that the intervention was most effective for narrative (vs. expository) texts and easy (vs. more difficult) texts. Dual language learners (DLLs) with lower initial English reading comprehension abilities benefitted more from the intervention than those with stronger reading skills. Results from Study 2 indicated that oral fine motor abilities predicted Spanish (but not English) oral language abilities in the expected direction (i.e. faster performance associated with higher language scores). The speed of /pata/ productions predicted reading comprehension during the intervention, but not in the expected direction (i.e. slower speeds associated with higher accuracy). Manual fine motor performance on tapping tasks was not related to language or reading.
Conclusions: The EMBRACE intervention has promise for use with at-risk DLLs. Future research should take care to match text difficulty with child skills so as to maximize benefit from the intervention. Oral fine motor abilities were related to language abilities in DLLs, but only for the native language. Slower oral fine motor performance predicted higher accuracy on intervention questions, suggesting that EMBRACE may be particularly effective for children with weak fine motor skills.
Method: Ninety, 4- and 5-year-old Navajo preschoolers with LI and with TD language were selected. Children completed the PEARL, which measured both language comprehension and production using pretest and posttest scores, and a modifiability scale. In addition, children completed the Clinical Evaluation of Language Fundamental, Preschool, Second Edition (CELF – Preschool 2) and language samples. A Navajo Speech Language Pathologist confirmed the diagnosis of the participants. Research assistants pretested, briefly taught the principles of narrative structure (story grammar, language complexity and episode) and evaluated response to learning using an index of modifiability.
Results: Results of discriminant analysis indicated that PEARL pretest differentiated both ability groups with 89% accuracy. In addition, posttest scores discriminated with 89% accuracy and modifiability scores with 100% accuracy. Further, the subtest story grammar was the best predictor at pretest and posttest, although modifiability scores were better predictors of both ability groups.
Conclusion: Findings indicate that the PEARL is a promising assessment for accurately differentiating Navajo preschool children with LI from Navajo preschool children with TD language. The PEARL’s recommended pretest cut score over-identified Navajo children with TD language; therefore, a new recommended cut score was determined.
This paper will cover topics regarding remote work. More specifically, remote work for the field of logistics. It will also dive into remote work platforms themselves e.g., Slack, Zoom, etc. Microsoft Teams, the specific software we used while I was at my internship, will be analyzed as well. I will, specifically, be analyzing the fundamental issues that occurred during my internship, developing a feasible solution with a laid-out process for each one. After the proper execution of these processes, I will discuss my results. I found that time is the most critical component of an optimal transition to remote work. Finally, I will conclude with reflections on my findings, insights from current working supply chain professionals, and prompt further research that could be done.
This project examines methods of evaluating the quality of digital UI/UX design including the McKinsey Design Index, heuristics, and design principles.
The contemporary world is motivated by data-driven decision-making. Small 501(c)3 nonprofit organizations are often limited in their reach due to their size, lack of funding, and a lack of data analysis expertise. In an effort to increase accessibility to data analysis for such organizations, a Founders Lab team designed a product to help them understand and utilize geographic information systems (GIS) software. This product – You Got GIS – strikes the balance between highly technical documentation and general overviews, benefiting 501(c)3 nonprofits in their pursuit of data-driven decision-making. Through the product’s use of case studies and methodologies, You Got GIS serves as a thought experiment platform to start answering questions regarding GIS. The product aims to continuously build partnerships in an effort to improve curriculum and user engagement.
As part of the Founders’ lab program, this thesis explores a social venture idea whose concept is to connect the philanthropic community with individuals and organizations in need of funding a project relating to (Sustainable Development Goals) SDG indicators through a peer-to-peer donation-based crowdfunding platform. Through this platform, the philanthropic community will have the possibility to easily access a wide range of projects to support as well as underserved individuals and communities seeking help, track their impact, donate in a complete transparent donation process, and automate donations through bank card round-ups. This social venture idea has been named PhilanthroGo.
Have new fraud and earnings manipulation detecting tools improved confidence in capital markets? To answer this question, I will provide a survey of tools currently used to detect fraud and earnings manipulation, discuss the effects of fraud and earnings manipulation, and look at changes in historical records of consumer confidence and investment returns as a test to our question.
