Typology Of Teacher Leadership Programs, Jill Harrison Berg, Peter Horn, Jonathan A. Supovitz, Jason Margolis Jan 2019

Typology Of Teacher Leadership Programs, Jill Harrison Berg, Peter Horn, Jonathan A. Supovitz, Jason Margolis

CPRE Research Reports

Education leaders are perennially seeking new ways to build the capacity of teachers to enhance learning experiences for all students. Teacher leadership, which we define as teachers’ support of the improvement of teaching and learning beyond their own classroom, has long been a source of interest and experimentation (Wenner & Campbell, 2017; York-Barr & Duke, 2004). Teacher leadership recognizes teachers’ instructional expertise as an asset for educational improvement, capitalizes upon teachers’ relationships with their colleagues to support change, and may provide career advancement opportunities to improve job satisfaction and the professionalization of teaching. For these and other reasons, states, districts, funders and teachers themselves have become increasingly interested in the promise of teacher leadership.

In this study, we map the landscape of teacher leadership programs across the U.S. and identify commonalities and distinctions amongst the range of programs. Using a variety of search approaches to capture publicly-available information, we document 285 state, local, university, and foundation-sponsored programs that use a variety of techniques to support teachers as leaders. We then categorize the forms of support, attending to program models, objectives, sponsorship, and audience.

We identify three major forms of support provided by teacher leadership programs: (1) preparation of teachers with knowledge and skills that can help them to lead; (2) positioning of teachers in leadership roles to capitalize upon their expertise; and (3) recognition of teachers as leaders through awards and other forms of appreciation or acknowledgement. While some programs focus only on one of these approaches, most employed a combination of these forms of support. Based on this ...


Monasteries Of The Future, Miles G. Bukiet Aug 2018

Monasteries Of The Future, Miles G. Bukiet

Master of Applied Positive Psychology (MAPP) Capstone Projects

For millennia, monasteries have been at the forefront of training virtues such as compassion, transcendence, service, gratitude, forgiveness, and grit, as well as foundational psychological capacities such as self-regulation, sustained, voluntary attention, emotional intelligence, and meta-cognitive awareness. Monasteries of the Future are modern institutions, both secular and religious, designed to provide the requisite financial, social, intellectual, and instructional support necessary to train a new generation of contemplative adepts. Forming a network of centers which collaborate and compete, Monasteries of the Future will establish and uphold the highest standards in the contemplative field. By partnering with modern science, most notably positive ...


School Vouchers In The Trump Era: How Political Ideology And Religion Shape Public Opinion, Rand Quinn, Tina Cheuk Jan 2018

School Vouchers In The Trump Era: How Political Ideology And Religion Shape Public Opinion, Rand Quinn, Tina Cheuk

CPRE Policy Briefs

Expanding school vouchers is a central component of the Trump Administration’s education agenda.1 However, the extent to which the Administration can fully realize this policy goal may hinge, in part, on the level of public support or opposition for the voucher method of reform and on the particular components of any proposed voucher system. In this policy brief, we report on a randomized survey experiment we conducted to identify how two key dimensions of school voucher systems—source of funding and scope of coverage—affect public opinion across various sectors of the American public.


Let's Talk About Sex: Why The Topic Of Sexual Violence Prevention Should Be Prioritized In K-12 Sex Education, Abbie Starker Mar 2017

Let's Talk About Sex: Why The Topic Of Sexual Violence Prevention Should Be Prioritized In K-12 Sex Education, Abbie Starker

CUREJ - College Undergraduate Research Electronic Journal

While campus sexual assault has recently garnered a lot of attention in the United States, there has been less recognition of individuals who experience sexual and gender-based violence outside of the university/college system. Many people who experience sexual violence have never attended a post-secondary institution, or they experienced sexual violence before they were college-aged. Because of this reality, it is important that there are resources and education about sexual violence for people at a younger age. Through an analysis of public policy, interviews with experts in the field, and a survey that I administered, this thesis examines both formal ...

#Commoncore Project (2017) How Social Media Is Changing The Politics Of Education, Jonathan A. Supovitz, Christian Kolouch, Alan J. Daley, Miguel Del Fresno

The #commoncore Project—How Social Media is Changing the Politics of Education

Fueled by impassioned social media activists, the Common Core State Standards have been a persistent flashpoint in the debate over the direction of American education. In this innovative and interactive website we explore the Common Core debate on Twitter. Using a distinctive combination of social network analyses and psychological investigations we reveal both the underlying social structure of the conversation and the motivations of the participants. The central question guiding our investigation is: How are social mediaenabled social networks changing the discourse in American politics that produces and sustains social policy?

Randomized Controlled Trials, Robert Boruch, Rui Yang, Jordan Hyatt, Herb Turner Iii Oct 2016

Randomized Controlled Trials, Robert Boruch, Rui Yang, Jordan Hyatt, Herb Turner Iii

GSE Publications

This paper covers the topic of randomized controlled trials in social, educational, criminological, health, and other human service sectors. It is studded with illustrations from developed and developing countries. We address the basic ideas that underlie trials in different ways, and cover contemporary definitions and vernacular, some history, and idea of cumulating evidence from such trials including recent work on replication and meta-analyses. Standards for evidence and reporting are considered. We attend to statistical matters and also recognize important non-statistical matters that must be taken into account in designing and executing such trials. Cluster randomized, place randomized, and other designs ...


Ambient Positional Instability Among Ohio Math And Science Teachers: 2008 To 2014, John Baker, Robert Boruch Apr 2015

Ambient Positional Instability Among Ohio Math And Science Teachers: 2008 To 2014, John Baker, Robert Boruch

GSE Publications

This briefing is on teacher retention and Ambient Positional Instability (API) rates from 2008-09 to 2013-14 for math and science teachers in the state of Ohio. API is investigated in two ways; first, the cohort of math and science teachers teaching in the 2008-09 school year are followed over five years and, second, the population of math and science teachers are tracked from one year to the next over the same time period. Data analyses are presented with key findings identified. Instability rates tend to be stable year-to-year. Teachers in non-charter public schools in the five largest cities in Ohio ...


Taken Out Of Context: Defending Civic Education From The Situationist Critique, Sigal R. Ben-Porath, Gideon Dishon Jan 2015

Taken Out Of Context: Defending Civic Education From The Situationist Critique, Sigal R. Ben-Porath, Gideon Dishon

GSE Publications

Situationists have suggested that educational efforts to improve character and instill virtues should be abandoned, as individuals’ behavior is predicted by contexts and situations rather than by character traits. More recently it has been suggested that civic education and especially the effort to cultivate civic virtues are ineffective for similar reasons and should be replaced by the introduction of desirable social norms and institutions. After surveying the debate on this topic in the first part of the essay, we suggest that in fact virtues should not be judged as existing within one person and absent from another based on their ...


Evaluation Of The I3 Scale-Up Of Reading Recovery | Year Two Report, 2012-13, Henry May, Heather Goldsworthy, Michael Armijo, Abigail M. Gray, Philip M Sirinides, Toscha J. Blalock, Helen Anderson-Clark, Andrew J. Schiera, Horatio Blackman, Jessica Gillespie, Cecile Sam Dec 2014

Evaluation Of The I3 Scale-Up Of Reading Recovery | Year Two Report, 2012-13, Henry May, Heather Goldsworthy, Michael Armijo, Abigail M. Gray, Philip M Sirinides, Toscha J. Blalock, Helen Anderson-Clark, Andrew J. Schiera, Horatio Blackman, Jessica Gillespie, Cecile Sam

CPRE Research Reports

Reading Recovery 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 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 Investing in Innovation (i3) Fund to expand the use of Reading ...

Improving Educational Quality Through Enhancing Community Participation: Results From A Randomized Field Experiment In Indonesia, Menno Pradhan, Daniel Suryadarma, Amanda Beatty, Maisy Wong, Arya Gaduh, Armida Alisjahbana, Rima Prama Artha Apr 2014

Improving Educational Quality Through Enhancing Community Participation: Results From A Randomized Field Experiment In Indonesia, Menno Pradhan, Daniel Suryadarma, Amanda Beatty, Maisy Wong, Arya Gaduh, Armida Alisjahbana, Rima Prama Artha

Real Estate Papers

Education ministries worldwide have promoted community engagement through school committees. This paper presents results from a large field experiment testing alternative approaches to strengthen school committees in public schools in Indonesia. Two novel treatments focus on institutional reforms. First, some schools were randomly assigned to implement elections of school committee members. Another treatment facilitated joint planning meetings between the school committee and the village council (linkage). Two more common treatments, grants and training, provided resources to existing school committees. We find that institutional reforms, in particular linkage and elections combined with linkage, are most cost-effective at improving learning.


Holding The Hunger Games Hostage At The Gym: An Evaluation Of Temptation Bundling, Katherine L. Milkman, Julia A. Minson, Kevin. G. Volpp Feb 2014

Holding The Hunger Games Hostage At The Gym: An Evaluation Of Temptation Bundling, Katherine L. Milkman, Julia A. Minson, Kevin. G. Volpp

Operations, Information and Decisions Papers

We introduce and evaluate the effectiveness of temptation bundling—a method for simultaneously tackling two types of self-control problems by harnessing consumption complementarities. We describe a field experiment measuring the impact of bundling instantly gratifying but guilt-inducing “want” experiences (enjoying page-turner audiobooks) with valuable “should” behaviors providing delayed rewards (exercising). We explore whether such bundles increase should behaviors and whether people would pay to create these restrictive bundles. Participants were randomly assigned to a full treatment condition with gym-only access to tempting audio novels, an intermediate treatment involving encouragement to restrict audiobook enjoyment to the gym, or a control condition ...


Information And Quality When Motivation Is Intrinsic: Evidence From Surgeon Report Cards, Jonathan T. Kolstad Dec 2013

Information And Quality When Motivation Is Intrinsic: Evidence From Surgeon Report Cards, Jonathan T. Kolstad

Health Care Management Papers

If profit maximization is the objective of a firm, new information about quality should affect firm behavior only through its effects on market demand. I consider an alternate model in which suppliers are motivated by a desire to perform well in addition to profit. The introduction of quality "report cards" for cardiac surgery in Pennsylvania provides an empirical setting to isolate the relative role of extrinsic and intrinsic incentives in determining surgeon response. Information on performance that was new to surgeons and unrelated to patient demand led to an intrinsic response four times larger than surgeon response to profit incentives.

Risk Management And Climate Change, Howard Kunreuther, Geoffrey Heal, Myles Allen, Ottmar Edenhofer, Christopher B. Field, Gary Yohe May 2013

Risk Management And Climate Change, Howard Kunreuther, Geoffrey Heal, Myles Allen, Ottmar Edenhofer, Christopher B. Field, Gary Yohe

Operations, Information and Decisions Papers

The selection of climate policies should be an exercise in risk management reflecting the many relevant sources of uncertainty. Studies of climate change and its impacts rarely yield consensus on the distribution of exposure, vulnerability or possible outcomes. Hence policy analysis cannot effectively evaluate alternatives using standard approaches, such as expected utility theory and benefit-cost analysis. This Perspective highlights the value of robust decision-making tools designed for situations such as evaluating climate policies, where consensus on probability distributions is not available and stakeholders differ in their degree of risk tolerance. A broader risk-management approach enables a range of possible outcomes ...


Correcting The Past: Failures To Replicate Psi, Jeff Galak, Robyn. A. Leboeuf, Leif. D. Nelson, Joseph. P. Simmons Dec 2012

Correcting The Past: Failures To Replicate Psi, Jeff Galak, Robyn. A. Leboeuf, Leif. D. Nelson, Joseph. P. Simmons

Operations, Information and Decisions Papers

Across 7 experiments (N = 3,289), we replicate the procedure of Experiments 8 and 9 from Bem (2011), which had originally demonstrated retroactive facilitation of recall. We failed to replicate that finding. We further conduct a meta-analysis of all replication attempts of these experiments and find that the average effect size (d = 0.04) is no different from 0. We discuss some reasons for differences between the results in this article and those presented in Bem (2011).


Protective Measures, Personal Experience, And The Affective Psychology Of Time, Ellen Peters, Howard Kunreuther, Namika Sagara, Paul Slovic, Dan R. Schley Dec 2012

Protective Measures, Personal Experience, And The Affective Psychology Of Time, Ellen Peters, Howard Kunreuther, Namika Sagara, Paul Slovic, Dan R. Schley

Operations, Information and Decisions Papers

We examined the role of time and affect in intentions to purchase a risk-protective measure (Studies 1 and 2) and explored participant abilities to factor time into the likelihood judgments that presumably underlie such intentions (Study 3). Participants worried more about losing their possessions and were more likely to purchase a protective measure given a longer term lease than a short-term lease, but only if their belongings were described in affect-poor terms. If described instead as being particularly special and affect-rich, participants neglected time and were about equally likely to purchase a risk-protective measure for shorter and longer term leases ...


Causal Effects Of Single-Sex Schools On College Entrance Exams And College Attendance: Random Assignment In Seoul High Schools, Hyunjoon Park, Jere R. Behrman, Jaesung Choi Jan 2012

Causal Effects Of Single-Sex Schools On College Entrance Exams And College Attendance: Random Assignment In Seoul High Schools, Hyunjoon Park, Jere R. Behrman, Jaesung Choi

PSC Working Paper Series

Despite the voluminous literature on the potentials of single-sex schools, there is no consensus on the effects of single-sex schools because of student selection of school types. We exploit a unique feature of schooling in Seoul, the random assignment of students into single-sex versus coeducational high schools, to assess causal effects of single-sex schools on college entrance exam scores and college attendance. Our validation of the random assignment shows comparable socioeconomic backgrounds and prior academic achievement of students attending single-sex schools and coeducational schools, which increases the credibility of our causal estimates of single-sex school effects. Attending all-boys schools or ...


Usercentric Operational Decision Making In Distributed Information Retrieval, Kartik Hosanagar Dec 2011

Usercentric Operational Decision Making In Distributed Information Retrieval, Kartik Hosanagar

Operations, Information and Decisions Papers

Information specialists in enterprises regularly use distributed information retrieval (DIR) systems that query a large number of information retrieval (IR) systems, merge the retrieved results, and display them to users. There can be considerable heterogeneity in the quality of results returned by different IR servers. Further, because different servers handle collections of different sizes and have different processing and bandwidth capacities, there can be considerable heterogeneity in their response times. The broker in the DIR system has to decide which servers to query, how long to wait for responses, and which retrieved results to display based on the benefits and ...


From Policy To Practice: Implementation Of The Legislative Objectives Of Charter Schools, Katherine M Barghaus, Erling E. Boe Nov 2011

From Policy To Practice: Implementation Of The Legislative Objectives Of Charter Schools, Katherine M Barghaus, Erling E. Boe

GSE Publications

Key legislative objectives of charter schools are to provide more school and classroom options, increase teacher influence over decision making, and increase school autonomy from state and district policy. Using national data from the 2003–4 School and Staffing Survey, we found that charter schools attained these legislative objectives when compared with regular schools, although increases in teacher influence and school autonomy were modest. Although charter schools have been implemented much as intended by legislation, other research has shown that charter schools in general have not improved student achievement—a major objective of charter school legislation. Our results suggest that ...


Intuitive Biases In Choice Versus Estimation: Implications For The Wisdom Of Crowds, Joseph P. Simmons, Lief D. Nelson, Jeffrey Galak, Shane Fredrick Jun 2011

Intuitive Biases In Choice Versus Estimation: Implications For The Wisdom Of Crowds, Joseph P. Simmons, Lief D. Nelson, Jeffrey Galak, Shane Fredrick

Operations, Information and Decisions Papers

Although researchers have documented many instances of crowd wisdom, it is important to know whether some kinds of judgments may lead the crowd astray, whether crowds’ judgments improve with feedback over time, and whether crowds’ judgments can be improved by changing the way judgments are elicited. We investigated these questions in a sports gambling context (predictions against point spreads) believed to elicit crowd wisdom. In a season-long experiment, fans wagered over $20,000 on NFL football predictions. Contrary to the wisdom-of-crowds hypothesis, faulty intuitions led the crowd to predict “favorites” more than “underdogs” against point spreads that disadvantaged favorites, even ...


Federal Policy And The Rise In Disability Enrollment: Evidence For The Veterans Affairs’ Disability Compensation Program, Mark Duggan May 2010

Federal Policy And The Rise In Disability Enrollment: Evidence For The Veterans Affairs’ Disability Compensation Program, Mark Duggan

Health Care Management Papers

The U.S. Department of Veterans Affairs compensates 13 percent of the nation’s military veterans for service‐related disabilities through the Disability Compensation (DC) program. In 2001, a legislative change made it easier for Vietnam veterans to receive benefits for diabetes associated with military service. In this paper, we investigate this policy’s effect on DC enrollment and expenditures as well as the behavioral response of potential beneficiaries. Our findings demonstrate that the policy increased DC enrollment by 6 percentage points among Vietnam veterans and that an additional 1.7 percent experienced an increase in their DC benefits, which ...


Group Cooperation Under Uncertainty, Min Gong, Joanne Baron, Howard Kunreuther Dec 2009

Group Cooperation Under Uncertainty, Min Gong, Joanne Baron, Howard Kunreuther

Operations, Information and Decisions Papers

Previous research has shown an ‘interindividual-intergroup discontinuity effect’: intergroup interactions generally lead to less cooperative outcomes than interindividual interactions. We replicate the discontinuity effect in the deterministic prisoner’s dilemma, but find that groups are more cooperative than individuals in a stochastic version of the game. Three major factors that underlie the usual discontinuity effect are reduced in the stochastic environment: greed, fear, and persuasion power. Two group mechanisms are proposed to explain the reversed discontinuity effect: the motivation to avoid guilt and blame when making decisions that affect others’ welfare, and the social pressure to conform to certain norms ...


Purchasing, Pricing, And Quick Response In The Presence Of Strategic Consumers, Gerard. P. Cachon, Robert Swinney Mar 2009

Purchasing, Pricing, And Quick Response In The Presence Of Strategic Consumers, Gerard. P. Cachon, Robert Swinney

Operations, Information and Decisions Papers

We consider a retailer that sells a product with uncertain demand over a finite selling season. The retailer sets an initial stocking quantity and, at some predetermined point in the season, optimally marks down remaining inventory. We modify this classic setting by introducing three types of consumers: myopic consumers, who always purchase at the initial full price; bargain-hunting consumers, who purchase only if the discounted price is sufficiently low; and strategic consumers, who strategically choose when to make their purchase. A strategic consumer chooses between a purchase at the initial full price and a later purchase at an uncertain markdown ...


A Randomized, Controlled Trial Of Financial Incentives For Smoking Cessation., Kevin. G. Volpp, Andrea. B. Troxel, Mark. V. Pauly, Henry. A. Glick, Andrea Puig, David A. Asch, Robert Galvin, Jingsan Zhu, Fei Wan, Jill Deguzman, Elizabeth Corbett, Janet Weiner, Janet Audrain-Mcgovern Feb 2009

A Randomized, Controlled Trial Of Financial Incentives For Smoking Cessation., Kevin. G. Volpp, Andrea. B. Troxel, Mark. V. Pauly, Henry. A. Glick, Andrea Puig, David A. Asch, Robert Galvin, Jingsan Zhu, Fei Wan, Jill Deguzman, Elizabeth Corbett, Janet Weiner, Janet Audrain-Mcgovern

Health Care Management Papers

BACKGROUND: Smoking is the leading preventable cause of premature death in the United States. Previous studies of financial incentives for smoking cessation in work settings have not shown that such incentives have significant effects on cessation rates, but these studies have had limited power, and the incentives used may have been insufficient.

METHODS: We randomly assigned 878 employees of a multinational company based in the United States to receive information about smoking-cessation programs (442 employees) or to receive information about programs plus financial incentives (436 employees). The financial incentives were $100 for completion of a smoking-cessation program, $250 for cessation ...


Why Are The Disability Rolls Skyrocketing? The Contribution Of Population Characteristics, Economic Conditions, And Program Generosity, Mark Duggan, Scott. A. Imberman Jan 2009

Why Are The Disability Rolls Skyrocketing? The Contribution Of Population Characteristics, Economic Conditions, And Program Generosity, Mark Duggan, Scott. A. Imberman

Health Care Management Papers

This chapter, which addresses three categories of explanation—the characteristics of individuals insured by the Disability Insurance (DI) program, the state of the economy, and the generosity of program benefits—argues that the growth in DI rolls is likely to continue and perhaps accelerate going forward. The data indicate that the recessions of 1991 and 2001 can explain 24 percent of the growth in DI receipt among men and 12 percent of the growth among women. Changes in health during the past two decades have slowed rather than added to the growth of the DI rolls. DI awards for certain ...


Does Nonprofit Status Signal Quality?, Anup Malani, Guy David Jun 2008

Does Nonprofit Status Signal Quality?, Anup Malani, Guy David

Health Care Management Papers

A popular theory for why firms take nonprofit status is that it is a signal of quality. This paper offers a simple, empirical test of this theory. If nonprofit status signals quality, surely nonprofit firms would want to ensure that consumers are aware of this. A natural way for firms to do this is to indicate their nonprofit status in their advertising. Taking this cue, we conducted a survey of over 2,800 firms in the hospital, nursing home, or child care industries in order to determine whether nonprofit firms communicate their status to consumers on their Web sites or ...


On The Effects Of Consumer Search And Firm Entry In A Multiproduct Competitive Market, Gerard. P. Cachon, Christian Terwiesch, Yi Xu May 2008

On The Effects Of Consumer Search And Firm Entry In A Multiproduct Competitive Market, Gerard. P. Cachon, Christian Terwiesch, Yi Xu

Operations, Information and Decisions Papers

This paper studies a model in which consumers search among multiple competing firms for products that match their preferences at a reasonable price. We focus on how easier search, possibly due to the adoption of search-facilitating technologies such as the Internet, influences equilibrium prices, assortments, firm profits, and consumer welfare. Conventional wisdom suggests that easier search creates a competition-intensifying effect that puts pressure on firms to lower their prices and reduce assortments. However, in our model we demonstrate that search also exhibits a market-expansion effect that encourages firms to expand their assortment—easier search means that each firm is searched ...


Aching To Retire? The Rise In The Full Retirement Age And Its Impact On The Social Security Disability Rolls, Mark Duggan, Perry Singleton, Jae Song Aug 2007

Aching To Retire? The Rise In The Full Retirement Age And Its Impact On The Social Security Disability Rolls, Mark Duggan, Perry Singleton, Jae Song

Health Care Management Papers

The Social Security Amendments of 1983 reduced the generosity of Social Security retired worker benefits in the U.S. by increasing the program's full retirement age from 65 to 67 and increasing the penalty for claiming benefits at the early retirement age of 62. These changes were phased in gradually, so that individuals born in or before 1937 were unaffected and those born in 1960 or later were fully affected. No corresponding changes were made to the program's disabled worker benefits, and thus the relative generosity of Social Security Disability Insurance (SSDI) benefits increased. In this paper, we ...


Constraint-Based Ontology Induction From Online Customer Reviews, Thomas Lee May 2007

Constraint-Based Ontology Induction From Online Customer Reviews, Thomas Lee

Operations, Information and Decisions Papers

We present an unsupervised, domain-independent technique for inducing a product-specific ontology of product features based upon online customer reviews. We frame ontology induction as a logical assignment problem and solve it with a bounds consistency constrained logic program. Using shallow natural language processing techniques, reviews are parsed into phrase sequences where each phrase refers to a single concept. Traditional document clustering techniques are adapted to collect phrases into initial concepts. We generate a token graph for each initial concept cluster and find a maximal clique to define the corresponding logical set of concept sub-elements. The logic program assigns tokens to ...
