Curriculum Reform in The Common Core Era: Evaluating Elementary Math Textbooks Across Six U.S. States

Can a school or district improve student achievement simply by switching to a higher-quality textbook or curriculum? We conducted the first multi-textbook, multi-state effort to estimate textbook efficacy following widespread adoption of the Common Core State Standards (CCSS) and associated changes in the textbook market. Pooling textbook adoption and student test score data across six geographically and demographically diverse U.S. states, we found little evidence of differences in average achievement gains for schools using different math textbooks. We found some evidence of greater variation in achievement gains among schools using pre-CCSS editions, which may have been more varied in their content than post-CCSS editions because they were written for a broader set of standards. We also found greater variation among schools that had more exposure to a given text. However, these differences were small. Despite considerable interest and attention to textbooks as a low-cost, “silver bullet” intervention for improving student outcomes, we conclude that the adoption of a new textbook or set of curriculum materials, on its own, is unlikely to achieve this goal.     

Is an exemption from US groundwater regulations a loophole or a noose?

In the United States, the Safe Drinking Water Act (SDWA) regulates most groundwater used for drinking water. The Act covers most urban areas but because it does not cover small water systems, it implicitly exempts nearly half of those living in rural America. In large measure, monitoring required by the SDWA has illustrated the prevalence of naturally occurring arsenic in groundwater in concentrated areas throughout the country. Even though many in Congress seem aware of this threat and have, indeed, supported more stringent arsenic standards, Congress, on the whole, has failed to update the SDWA to cover those water systems left unprotected by the Act. Conventional political science theory suggests that effective congressional oversight depends on Congress creating both active (e.g., hearings and commissioned studies) and passive oversight mechanisms (i.e., citizen suits and opportunities for constituent feedback). In this case, Congress had, in fact, created sufficient tools to detect a serious problem but, having identified it, nevertheless failed to respond. Why? In exploring Congress’s inaction, we find something unexpected: the structure of the SDWA has created perverse incentives not only for unregulated water systems but also for regulated systems to push to keep exempted water systems unregulated. The outcome is that those outside of the SDWA’s protections remain outside and continue to drink contaminated water by the glass full. So, while Congress created a loophole, it may have inadvertently tied a noose.     

Fleeting fame under the Trademark Dilution Revision Act of 2006

Legal context: When Congress enacted the Federal Trademark Dilution Act in1996, it intended to create a uniform federal cause of actionfor trade mark dilution. Unfortunately, the statutory languageselected by Congress created certain ambiguities, includinghow famous a trade mark had to be to merit dilution protectionunder the statute. Confusion developed as to whether a markmerely needed renown in a limited geographic area or industry—aconcept that became known as ‘niche fame’—orwhether it needed national renown to qualify as a ‘famousmark’. Key points: In 2006, Congress enacted the Trademark Dilution Revision Actand therein provided a concrete definition for a famous markthat ostensibly removed the ability to qualify for dilutionrelief where the mark was famous only within a particular niche.It was uncertain how courts that had previously favoured theniche fame theory would apply Congress's new definition. However,a district court in the Ninth Circuit, one of the strongestproponents of niche fame, recently held that niche fame is nolonger a viable theory under the Lanham Act or California statelaw as a result of the 2006 amendment. Practical significance: This decision portends that courts will fall in line with Congress'samendment and will deny dilution relief under federal law toparties whose marks are famous only in a particular geographicarea or industry. Additionally, the decision provides some guidanceand predictability as to how states may interpret the viabilityof niche fame under their respective dilution statutes in lightof Congress's 2006 amendment.     

Prospective Person Memory: The Role of Self-Efficacy,Personal Interaction,and Multiple Images in Recognition of Wanted Persons

Prospective person memory refers to recognition of individuals one has been asked to be on the lookout for, such as wanted criminals or missing persons. Past field experiments have tended to find very low rates of identification. The present experiments examine whether multiple pictures, personal interaction, and increased self-efficacy would improve prospective person memory. Participants viewed a mock wanted person alert and were told that if they saw the person depicted in the alert they could win a cash prize. The alert either showed a single picture of the target person or multiple pictures. The target individual then showed up at the dining hall participants routinely had lunch. Some participants had peronal interaction with the target and some participants were led to believe that the likelihood of encounter was quite high. Despite these manipulations, only a small number of participants reported seeing the target individual.     

The listen to me project: Creating lasting changes in voice and participation for children in care through a youth-led project

In this article, we present the results from a youth-led project on the voices and participation of children in state care in Ontario, Canada. The purpose of this project was for youth to share their voice about what they wish child protection workers and agencies could do to improve their experiences within the child protection system. Many youth in care in Canada and internationally report that their voices are not heard and that they are not involved in decisions involving their care. Seven themes were extracted from this voices of youth project asking child welfare workers and agencies to listen to [them] and believe [them], keep [them] informed and be honest, involve [them] in decisions, support [them], keep [them] connected,; ignite [their] passions, and don't give up on [them]. Suggestions from the youth involved in this project are offered on ways to create true and meaningful change in child welfare.     

A Test of Sex Estimation in Subadults Using the Elevation of the Auricular Surface from Four Samples of Known Age and Sex

Biological sex is foundational to the work of forensic anthropologists and bioarcheologists. The lack of reliable biological sex estimation methods for subadults has, thus, greatly limited forensic and bioarcheological analyses. Auricular surface elevation showed promise as a subadult sex estimation method in previous studies. This study examined two auricular surface elevation evaluation methods on four subadult samples of known age, sex, and ancestry. Samples were scored as “male,” “female,” or “indeterminate” and results were examined with chi‐square analysis. No consistent sex estimation pattern, accuracy, or predictive value was produced between samples. Only one test was significant using Fisher's exact test analysis (FET = 7.501, p < 0.022): the composite approach on the Hamann‐Todd sample. While age, sample size, or developmental factors may play a role in these results, clearly sample variation does as well. This study found auricular surface elevation was not a useful subadult sex estimation method.     

Metric Assessment of the Pubic Bone Using Known and Novel Data Points for Sex Estimation,

Biological sex estimation of skeletal remains is essential in forensic and archaeological analyses. Anthropologists most often use the pelvis, which is the most sexually dimorphic element both morphologically and metrically. While nonmetric pubic bone features have been studied extensively, few metric studies have examined this individual bone for dimorphism. For this study, three observers examined three previously identified and ten novel measurements of the pubic body on a modern sample of isolated pubic bones from the Maricopa County Forensic Science Center (FSC), in Phoenix, Arizona (n = 400). A relationship between pubic body measurements and biological sex was demonstrated, with significant correlations. Discriminant function analyses found that five measurements, four of which were novel, discriminated between males (89%) and females (86%). Observer experience level did not significantly impact the results. These five measurements were reliable and show promise for inclusion in metric methods for assessment of sex.
