Cumulative Advantage And Student Performance In General Chemistry: An Empirical Study At A Midwest Tier 1 University (2016-2019), Nicole Barvian

Dissertations

General chemistry (GC) plays a crucial role in the academic and career outcomes of students interested in postsecondary science, engineering and medicine. As a whole, chemistry education research literature has reported student attrition rates averaging from 25% to 35% for nearly a century. Student attrition rates can be attributed to a number of factors, including high school preparation (e.g. Tai et al. 2006), opportunity to learn (Carroll, 1989) and accumulated time and practice in a domain (e.g. Ericsson et al. 1993). The factors, in turn, are affected by mechanisms of social stratification, in particular, the social mechanism of cumulative advantage …

Evaluating Middle School English Language Learners’ Science And Literacy Proficiency, Yasemin Ozkaya

Dissertations

The academic success and English proficiency of ELL students are receiving more attention as a result of the growing number of ELL students and the demand for accountability and assessment in education. It is widely accepted that ELL students struggle on state standardized tests because they lack the cognitive academic language abilities needed to succeed on extensive subject evaluations (Thakkar, 2013). According to Abedi and Dietel, ELLs' academic performance lags behind that of other segments of population, and the attainment gap reduces only slightly over time (2004).

Impact Of An Active Learning Intervention On Student Success In An Introductory-Level Biology Course, Cynthia Littlejohn

Dissertations

Large enrollment introductory-level courses with high rates of students receiving a D, F, or withdrawing have been identified within higher education as gateway courses. Students not successfully completing these courses are disproportionately represented by historically and continually marginalized populations, such as low-income, poorly represented ethnic groups, and first-generation students. A form of blended learning called the flipped class model is becoming increasingly prevalent in gateway courses. A flipped class design may reduce the cognitive load by allowing time for processing information before class while cooperative learning may result in a collective working memory effect where social interactions may serve to …
