A Project-Based Approach to Statistics and Data Science

Abstract

In an increasingly data-driven world, facility with statistics is more important than ever for our students. At institutions without a statistician, it often falls to the mathematics faculty to teach statistics courses. This paper presents a model that a mathematician asked to teach statistics can follow. This model entails connecting with faculty from numerous departments on campus to develop a list of topics, building a repository of real-world datasets from these faculty, and creating projects where students interface with these datasets to write lab reports aimed at consumers of statistics in other disciplines. The end result is students who are well prepared for interdisciplinary research, who are accustomed to coping with the idiosyncrasies of real data, and who have sharpened their technical writing and speaking skills.

Prenatal Neighborhood Ethnocultural Context and the Mental Health of Mothers and Children in Low-Income Mexican American Families

Socioeconomically disadvantaged neighborhoods increase the risk for poor mental health among residents, yet protective factors may operate alongside risk. This study evaluated the influence of the prenatal neighborhood ethnocultural context on child behavior problems and maternal depressive symptoms. Prenatal maternal role expectations, prenatal culture-specific stress, and postpartum depression (PPD) symptoms were evaluated as mediators. Participants included 322 low-income, Mexican American mother-child dyads. Women (M_age = 27.8) reported on proposed mediators, maternal depressive symptoms, and child behavior problems at 4.5 years. Neighborhood Latinx concentration was obtained from census data. Higher Latinx concentration predicted fewer maternal depressive symptoms and child behavior problems, mediated through role expectations and PPD symptoms. Results suggest prenatal neighborhood context to impact later maternal and child mental health.

Long-term effects of child punishment on Mexican women: a structural model

OBJECTIVE: The aim of this study was to investigate long-term effects of parental use of physical and verbal punishment on Mexican women. To study both direct and indirect effects of these phenomena, a structural model was developed and tested. METHOD: One hundred and fifty Mexican women were interviewed with regard to their history of child abuse, their level of depression, alcohol use, antisocial behavior, and punishment of their own children. Factors representing such constructs were specified within a structural equation model and their inter-relations were estimated. Women's history of abuse was considered as an exogenous latent variable directly affecting three other factors: mothers' antisocial behavior, their alcohol consumption, and their levels of depression or anxiety. These factors, in turn, were specified as influencing mothers' harsh discipline of their own children. RESULTS: Data supported this model, indicating that a history of abuse has long-term effects on women's behavior and psychological functioning, which in turn cause women's punitive behavior against their children. CONCLUSIONS: These results are discussed in terms of the theoretical framework of intergenerational transmission of violence. The direct consequences (depression, anxiety, alcohol consumption, and antisocial behavior) of child punishment act as risk factors for the next generation of child abuse.     

How newly qualified primary teachers develop: A case study in rural Eritrea

This paper reports on the professional development of a small group of newly qualified teachers (NQTs) who began their careers in four rural schools in Eritrea. These teachers were monitored over a period of four years from 2001 to 2004. Their development as primary practitioners was recorded by videoing and observing their classes and by interviews and informal discussions held over the period. The ways in which they developed and the factors involved in this development are analysed and discussed.It is hoped that this research offers an insight into the challenges faced by newly qualified teachers in small rural communities, often very much dependant on their own resources and those of the local community. This indicates ways in which the current programme and on-going in-service provision may be targeted in future. An important point is made that in spite of the unusual circumstances of education in Eritrea this research provides insights that are relevant to other sociocultural contexts.     

The experiences of lesbian,gay and bisexual students and staff at a Further Education college in South East England

Research exploring the educational experiences of lesbian, gay and bisexual (LGB) students and staff members has traditionally been characterised by homophobia, hostility, victimisation and marginalisation. Recent research has evidenced a shift in the experiences of LGB young people, to somewhat more accepting and positive narratives, including within post‐compulsory schooling. Yet, there is limited research exploring the lived experiences of LGB staff members in the Further Education context. Utilising inclusive masculinity as a sociological paradigm, this research explores the qualitative data from the narratives of 26 LGB staff and students at one Further Education college in the south of England. The results find a distinct lack of homophobia within this college, a nuanced understanding of homosexually themed language, and an organisational culture of inclusivity and widespread symbolic visibility of the LGB community. Overall, our research aligns with broader social patterns that the experiences for LGB persons is improving.
