Principal Ownership of an Instructional Initiative: Advancing a Conceptual Framework for the Study of Leadership
ABSTRACT
Principal Ownership of an Instructional Initiative: Advancing a Conceptual Framework for the Study of Leadership
Abigail Gray
There is a need for unified theory as to how and why principals\u27 engagement with instructional initiatives does or does not develop, and how that engagement manifests, both in specific leadership behaviors and in changes in teacher practice. Such theory could inform policy decision-making by shedding light on the mechanisms that may facilitate principals\u27 engagement with reform initiatives, and by clarifying what that engagement might ultimately produce. This study seeks to advance a new theoretical perspective on principal behavior in the context of instructional reform by examining the implementation of a literacy intervention through the lens of principal ownership. Using structural equation modeling and targeted qualitative inquiry, the study tests a hypothesized conceptual framework for principal ownership which posits that three antecedents (control, knowledge, and self-investment) contribute to principals\u27 engagement in ownership behavior relative to an instructional initiative. The framework further posits that this ownership behavior--specifically, change promotion relative to the initiative--leads to changes in teacher collaboration around the reform, and ultimately influences classroom practice. This framework builds upon extant theory regarding school leadership, the processes around school change, and psychological ownership. While further research is needed to confirm these findings, the results of this exploratory study suggest that the hypothesized relationships are plausible. Significant pathways are found between the antecedents and the ownership behavior, and between the behavior and teacher collaboration. Mediational analysis of the pathways between principals\u27 ownership behavior and the reform\u27s reported influence on classroom instruction reveals that both the direct pathway and the indirect pathway (mediated by teacher collaboration) are significant. The findings of case-study research focused on three schools largely support the SEM study\u27s conclusions and the hypothesized relationships. Viewed together, the quantitative and qualitative findings highlight lingering questions and directions for future research
The i3 Validation of SunBay Digital Mathematics
Decades of research have emphasized the need for engaging, accessible ways to help students learn fundamental mathematical concepts. Research also shows that teacher beliefs about teaching and learning have an outsized influence on the quality and effectiveness of curricular interventions. This article reports results of an independent evaluation of the i3 implementation of SunBay Digital Mathematics, a middle-school math intervention, and examines the programâs impacts on both student progress and teachersâ beliefs about math instruction. Prior studies have demonstrated the efficacy of SunBay Math for students of varied levels of prior achievement. This independent evaluation included a randomized controlled trial in 60 Florida middle schools during the 2015-16 school year and a mixed-methods implementation study. No impact on student achievement was observed overall; however, the evaluation did reveal positive impacts on teachersâ classroom practices and beliefs about the use of technology in math instruction. Inadequate implementation of instructional units and lack of impact on teachers for targeted beliefs about math instruction likely contributed to lack of overall program effects
Mineralogical Variation in Shells of the Blackfoot Abalone, Haliotis iris (Mollusca: Gastropoda: Haliotidae), in Southern New Zealand
The New Zealand blackfoot abalone, Haliotis iris Gmelin, is among
the few gastropods that precipitate both calcite and aragonite in their shells. The
location, composition, and thickness of these mineral layers may affect color,
luster, and strength of the shell, which is locally important in jewelry manufacture.
Skeletal mineralogy and shell structure of H. iris from three southern
New Zealand locations were determined using X-ray diffractometry, scanning
electron micrography, and mineral staining. In H. iris an outer calcitic layer is
separated from an inner aragonitic surface by both calcified and noncalcified
organic layers running longitudinally through the shell. Skeletal mineralogy
within individual shells varies from 29 to 98% aragonite, with older shell having
significantly higher aragonite content than young sections. Variation within
populations ranges from 40 to 98% aragonite, and among three populations
from 34 to 98% aragonite. Shell thickness, too, varies within individual shells
from 0.2 to 4.2 mm, with a significant positive relationship with age. Within population
variation in shell thickness ranges from 2.1 to 5.4 mm, with no
significant difference in shell thickness variation among populations. The high
degree of variability within and among individual shells suggests that it is
essential to test replicate samples from individual mollusk shells, especially when
they have complex bimineral structure
Reading Recovery: An Evaluation of the Four-Year i3 Scale-Up
CPRE released its evaluation of one of the most ambitious and well-documented expansions of a U.S. instructional curriculum. The rigorous independent evaluation of the Investing in Innovation (i3) scale-up of Reading Recovery, a literacy intervention for struggling first graders, was a collaboration between CPRE and the Center for Research on Education and Social Policy (CRESP) at the University of Delaware.
The CPRE/CRESP evaluation revealed that students who participated in Reading Recovery significantly outperformed students in the control group on measures of overall reading, reading comprehension, and decoding. These effects were similarly large for English language learners and students attending rural schools, which were the student subgroups of priority interest for the i3 scale-up grant program.
The study included an in-depth analysis of program implementation. Key findings focus on the contextual factors of the school and teachers that support the programâs success and the components of instructional strength in Reading Recovery
Discipline in Context: Suspension, Climate, and PBIS in the School District of Philadelphia
The report details a two-year exploratory, mixed-methods research study on the disciplinary practices and climate of schools serving Kâ8 students in the School District of Philadelphia (SDP). Findings reveal that SDP schools are making efforts to reduce suspensions and improve climate, but critical barriers to these efforts include resource limitations and philosophical misalignments between teachers and school leaders. The study identified three profiles among SDP schools serving Kâ8 students based on information about disciplinary practices and climate, and found that these profiles are predictive of suspension and academic outcomes. Students attending schools with collaborative climates and less punitive approaches to discipline have lower risk of being suspended and better academic outcomes. The report offers a series of recommendations for strengthening the implementation of climate initiatives, including Positive Behavioral Interventions and Supports (PBIS), in challenging urban settings

Evaluation of the i3 Scale-up of Reading Recovery | Year One Report, 2011-12
Reading Recovery (RR) is a short-term early intervention designed to help the lowest-achieving readers in first grade reach average levels of classroom performance in literacy. Students identified to receive Reading Recovery meet individually with a specially trained Reading Recovery (RR) teacher every school day for 30-minute lessons over a period of 12 to 20 weeks. The purpose of these lessons is to support rapid acceleration of each child's literacy learning. In 2010, The Ohio State University received a Scaling Up What Works grant from the U.S. Department of Education's Investing in Innovation (i3) Fund to expand the use of Reading Recovery across the country. The award was intended to fund the scale-up of Reading Recovery by training 3,675 new RR Teachers in U.S. schools, thereby expanding capacity to allow service to an additional 88,200 students.The Consortium for Policy Research in Education (CPRE) was contracted to conduct an independent evaluation of the i3 scale up of Reading Recovery over the course of five years. The evaluation includes parallel rigorous experimental and quasi-experimental designs for estimating program impacts, coupled with a large-scale mixed-methods study of program implementation under the i3 scale-up. This report presents findings through the second year of the evaluation. The primary goals of this evaluation were: a) to assess the success of the scale-up in meeting the i3 grant's expansion goals; b) to document the implementation of scale-up and fidelity to program standards; and, c) to provide experimental evidence of the impacts of Reading Recovery on student learning under this scale-up effort

This document is the second in a series of three reports based on our external evaluation of the Reading Recovery i3 Scale-Up. This report presents results from the impact and implementation studies conducted over the 2012-2013 school yearâthe third year of the scale-up effort and the second full year of the evaluation.
In order to estimate the impacts of the program, a sample of first graders who had been selected to receive Reading Recovery were randomly assigned to a treatment group that received Reading Recovery immediately, or to a control group that did not receive Reading Recovery until the treatment group had exited the intervention. The reading achievement of students in this sample was assessed using a standardized assessment of reading achievementâthe Iowa Tests of Basic Skills (ITBS). The data for the implementation study include extensive interviews and surveys with Reading Recovery teachers, teacher leaders, site coordinators, University Training Center directors, members of the i3 project leadership team at The Ohio State University, and principals and first-grade teachers in schools involved in the scale-up. Case studies were also conducted in nine i3 scale-up schools to observe how Reading Recovery operates in different contexts
Comparing Adult Cannabis Treatment-Seekers Enrolled in a Clinical Trial with National Samples of Cannabis Users in the United States
BackgroundâCannabis use rates are increasing among adults in the United States (US) while the perception of harm is declining. This may result in an increased prevalence of cannabis use disorder and the need for more clinical trials to evaluate efficacious treatment strategies. Clinical trials are the gold standard for evaluating treatment, yet study samples are rarely representative of the target population. This finding has not yet been established for cannabis treatment trials. This study compared demographic and cannabis use characteristics of a cannabis cessation clinical trial sample (run through National Drug Abuse Treatment Clinical Trials Network) with three nationally representative datasets from the US; 1) National Survey on Drug Use and Health, 2) National Epidemiologic Survey on Alcohol and Related Conditions-III, and 3) Treatment Episodes Data Set â Admissions.
MethodsâComparisons were made between the clinical trial sample and appropriate cannabis using sub-samples from the national datasets, and propensity scores were calculated to determine the degree of similarity between samples.
ResultsâResults showed that the clinical trial sample was significantly different from all three national datasets, with the clinical trial sample having greater representation among older adults, African Americans, Hispanic/Latinos, adults with more education, non-tobacco users, and daily and almost daily cannabis users.
ConclusionsâThese results are consistent with previous studies of other substance use disorder populations and extend sample representation issues to a cannabis use disorder population. This illustrates the need to ensure representative samples within cannabis treatment clinical trials to improve the generalizability of promising findings
Updated observing scenarios and multi-messenger implications for the International Gravitational-wave Network's O4 and O5
Advanced LIGO and Virgo's third observing run brought another binary neutron
star merger (BNS) and the first neutron-star black-hole (NSBH) mergers. While
no confirmed kilonovae (KNe) was identified in conjunction with any of these
events, continued improvements of analyses surrounding GW170817 allow us to
project constraints on the Hubble Constant (), the Galactic enrichment
from -process nucleosynthesis, and ultra-dense matter possible from
forthcoming events. Here, we describe the expected constraints based on the
latest expected event rates from the international gravitational-wave network
(IGWN) and analyses of GW170817. We show the expected detection rate of
gravitational waves and their counterparts, as well as how sensitive potential
constraints are to the observed numbers of counterparts. We intend this
analysis as support for the community when creating scientifically-driven
electromagnetic follow-up proposals. During the next observing run O4, we
predict an annual detection rate of electromagnetic counterparts from BNS of

Facility (Rubin Observatory)
