The purpose of this study was to develop and validate a survey of opportunities to participate (OtP) in science that will allow educators and researchers to closely approximate the types of learning opportunities students have in science classrooms. Additionally, we examined whether and how opportunity gaps in science learning may exist across…

We use nearly 430 million standardized test scores, including test scores from more than 6,500 rural school districts, to describe educational opportunity in rural America. Although we find modest differences in outcomes between rural and nonrural students overall, these disparities are larger for specific socioeconomic, racial-ethnic, and…

The Stanford Educational Data Archive (SEDA) is the first data set to allow comparisons of district academic achievement and growth from Grades 3 to 8 across the United States, shining a light on the distribution of educational opportunities. This study describes a convergent validity analysis of the SEDA growth estimates in mathematics and…

The problem addressed in this study was students who have not been able to demonstrate proficiency in performing mathematical computation, algebraic and geometrical reasoning, number sense proficiency and mathematical processing while in grades 3 through 8 are not prepared to successfully complete the high school high stakes Algebra 1 ECA…

Assessing Opportunities to Learn (OTL) implies the measurement of different aspects of the curricular implementation in the classrooms, such as the contents that the teacher selects for the course and the time of exposure and the frequency of the tasks proposed. Based on recent studies that demonstrate the influence of this curricular dimension on…

In response to the call for research on integrating best general practices in teaching with those that promote equity and access, we present a two-part study focused on instructional strategies that may remove learning barriers for English Language Learners. We theoretical developed and empirically explored supplemental components for traditional…

States' efforts to incorporate technology and engineering into K-12 science instruction appear to be bearing fruit: More than five years after states began adopting K-12 science standards that feature technology and engineering, eighth graders have notched higher scores on a national assessment of those subjects. This Policy Brief presents…

I use standardized test scores from roughly 45 million students to describe the temporal structure of educational opportunity in over 11,000 school districts--almost every district in the US. For each school district, I construct two measures: the average academic performance of students in grade 3 and the within-cohort growth in test scores from…

This study provides initial evidence supporting intended score interpretations for the purpose of assessing opportunity to learn (OTL) via an online teacher log. MyiLOGS yields 5 scores related to instructional time, content, and quality. Based on data from 46 middle school classes, the evidence indicated that (a) MyiLOGS has high usability, (b)…

The No Child Left Behind Act of 2001 has put many schools under a lot of pressure to meet its high demands. In this quantitative study, the effects that the NCLB act has had on students' opportunity to learn (OTL) and Subject Level Success (SS) from 2004 to 2012 in 9th, 10th, and 11th grade math coursework (Algebra 1, Geometry, Algebra 2, and…

The educational resources of schools play an important role in order to diminish the effect of socioeconomic features on academic achievement, and create equal opportunities for students. In this sense, it is highly crucial to investigate the relationship between the educational resources of schools and the academic achievement of students. This…

There is a gap in academic achievement, as evidenced on standardized tests, between European American, Latino American, and African American students in the United States. In 2011, the United States average scale scores for 8th grade students on the NAEP mathematics assessment for European American, Latino American, and African American students…

This dissertation consists of four chapters. Chapter 1 provides an introduction to the self-determination literature documenting the importance of promoting the self-determination of transition and secondary age students with disabilities, as well as a summary of research examining the self-determination of students with disabilities across…

This study investigates inter-school variations in several dimensions of opportunity to learn as well as examines the extent to which these measures significantly affect students' performance on grade 7 literacy and numeracy exams. After situating the study within the global discourse emphasizing the importance of providing access to quality…
