Three Essays in the Economics of Education: Dissertation Summary

This dissertation consists of three self-contained chapters investigating current issues in the economics of education. The first chapter investigates the effects of school closing policies on student achievement by examining over 200 school closings in Michigan. The second chapter examines the effects of a shortened school year policy on student achievement. Changing the length of the school year has dramatic potential effects for student achievement, but the magnitude of these effects will depend on the extent to which parents and teachers respond to the policy change. This study examines student achievement in public schools in Hawaii, which furloughed teachers on 17 Fridays during the 2009–2010 school year. The final chapter, coauthored with Seth Gershenson and Michael Hayes, looks at teacher grade reassignments in elementary schools. We use teacher-level micro data from Michigan to document the prevalence and distribution of grade-level reassignments across different types of schools and teachers

The "Autism epidemic" and Texas public schools : economic, educational, and ethical considerations for public school superintendents

textThe purported existence of an “autism epidemic" has been vociferously debated both in the popular media and in academic research. One oft-cited study suggests that newly identified diagnoses of autism have increased 30% over the preceding decade to the point of potentially afflicting as many as 1 in 68 students (Centers for Disease Control, 2014). This influx merits close evaluation given existing research which postulates the existence of relationships between rates of ASD identification and ethnic and socioeconomic factors (Bhasin & Schendel, 2007). This potential disparity, coupled with ongoing budgetary constraints, the inherent ambiguity of existing litigation, and changing demographic projections, presents a number of financial, legal, and ethical impediments for public school superintendents in their ongoing efforts to ensure the efficacy and equity of services for students with ASD. Accordingly, this study analyzed the existence of any potential correlations between rates of ASD identification (expressed as a percentage of enrolled students whose primary Texas Education Agency special education eligibility criteria is "AU" or autism) and other ethnic and socioeconomic subpopulations evaluated in Public Education Information Management System (PEIMS) data. Prospective correlations were examined at both the campus level for each respective elementary campus in the case study district and at the district level for each Texas public school district which participated in a due process hearing predicated by an “AU” eligibility (or lack thereof) for the 2006-2007 through 2013-2014 academic years. Research questions were analyzed using the Pearson Product Moment Correlation and Spearman's ρ Rank Order Correlation Coefficients. The magnitude of practical effect size was determined using the Cohen's d algorithm. This study returned the following selected results: 1. A statistically and practically significant positive relationship exists between percentage of campus "AU" enrollment and the percentage of campus enrollment for the White subpopulation. 2. Statistically and practically significant negative relationships exist between percentage of campus "AU" enrollment and the percentage of campus enrollment for the Hispanic and African-American subpopulations respectively. 3. Statistically and practically significant negative relationships exist between percentage of campus "AU" enrollment and the percentage of campus enrollment for the Economically Disadvantaged and At Risk subpopulations respectively.Educational Administratio

The Effect of Gender Inequality on Growth: A Cross-Country Empirical Study

Many papers investigating this topic have been subject to problems of multicollinearity. This paper seeks to avoid this problem by reformulating gender inequality as a ratio instead of simply examining female and male education as separate factors. The results indicate that, controlling for multicollinearity, high levels of gender inequality have a damping effect on growth. Furthermore, these results are robust to not only changes in included variables but changes in the specification of gender inequality

Create Pretty Documents with LaTeX!

LaTeX is a typesetting system for the educator who wants to create documents with beautifully typeset mathematics. It is free, available for all major platforms, and cross-platform compatible. In this workshop, we will introduce participants to LaTeX, and then demonstrate how to typeset a variety of documents (e.g., tests or presentations). We are happy to tailor the demonstration to answer any specific questions raised by participants. Please bring your laptop to get hands-on experience. This web page contains links to the handouts and the sample files: staff.imsa.edu/~fogel/late

Easy LaTeX for Math Teachers

LaTeX is a typesetting system for the educator who wants to create documents with beautifully typeset mathematics.
