Adapting to large-scale changes in Advanced Placement Biology,Chemistry, and Physics: the impact of online teacher communities

Over the past decade, the field of teacher professional learning has coalesced around core characteristics of high quality professional development experiences (e.g. Borko, Jacobs, & Koellner, 2010. Contemporary approaches to teacher professional development. In P. L. Peterson, E. Baker, & B. McGaw (Eds.), International encyclopedia of education (Vol. 7, pp. 548–556). Oxford: Elsevier.; Darling-Hammond, Hyler, & Gardner, 2017. Effective teacher professional development. Palo Alto, CA: Learning Policy Institute). Many countries have found these advances of great interest because of a desire to build teacher capacity in science education and across the full curriculum. This paper continues this progress by examining the role and impact of an online professional development community within the top-down, large-scale curriculum and assessment revision of Advanced Placement (AP) Biology, Chemistry, and Physics. This paper is part of a five-year, longitudinal, U.S. National Science Foundation–funded project to study the relative effectiveness of various types of professional development in enabling teachers to adapt to the revised AP course goals and exams. Of the many forms of professional development our research has examined, preliminary analyses indicated that participation in the College Board's online AP Teacher Community (APTC) – where teachers can discuss teaching strategies, share resources, and connect with each other – had positive, direct, and statistically significant association with teacher self-reported shifts in practice and with gains in student AP scores (Fishman et al., 2014). This study explored how usage of the online APTC might be useful to teachers and examined a more robust estimate of these effects. Findings from the experience of AP teachers may be valuable in supporting other large-scale curriculum changes, such as the U.S. Next Generation Science Standards or Common Core Standards, as well as parallel curricular shifts in other countries.     

Need for Cognition as a Mediating Variable Between Aggressive Communication Traits and Tolerance for Disagreement

This study examined the need for cognition as a mediator between aggressive communication traits and tolerance for disagreement. Previous research suggests that argumentativeness is a positive predictor of tolerance for disagreement, while verbal aggressiveness is a negative predictor of tolerance for disagreement. Our findings indicate that need for cognition positively mediates the relationship between argumentativeness and tolerance for disagreement, as well as verbal aggressiveness and tolerance for disagreement.     

Explaining Local Variability in Child Care Quality: State Funding and Regulation in California

The uneven availability of child-care centers for different kinds of families has been detailed in recent years. Much less is known about the distribution of center quality across communities. Nor do we understand the role that local contexts or state policies may play in shaping quality levels. This paper describes several quality indicators, based on reports of 170 center directors situated in three California counties. We found that most centers in lower-income and working-class communities displayed at least moderate levels of quality along structural measures, such as class size, the ratio of children per staff member, and staff education levels. About one in six failed to meet recommended quality standards. Some quality indicators were lower for centers located in communities with lower supply of center enrollment slots per capita, possibly due to excess family demand for center-based care. Center quality was not consistently influenced by community conditions such as poverty levels, ethnic composition, or maternal employment rates. Quality was higher among centers receiving stronger flows of public subsidies. We discuss the success of state agencies in advancing quality among centers and remaining policy challenges.     

Americans ‘support’ the idea of tuition-free college: an exploration of sentiment and political identity signals otherwise

In January 2015, President Obama captured headlines in the US by announcing America’s College Promise (ACP), a policy that would reverse four decades of privatisation in higher education by making community colleges ‘tuition-free’. This research explores the conversation that unfolded across the Facebook pages of various media sources. Key phrases associated with sentiments and communication styles are uncovered using a Bag of Words (BoW) technique. Next, guided by political identity theory, the researchers employ logistic regression to explore variable effects (e.g. source, gender, race, age and political leaning) on communicating: (1) Against ACP, (2) in a Civil manner, and (3) Against/Civil/On-Topic. BoW models suggest those against the policy utilise anti-free-ride, privatisation rhetoric, whereas those using uncivil language attack commentators and groups who counter personally-held political beliefs – while also introducing non-sequiturs from other policies (e.g. healthcare and immigration). The combined communication styles unlocked tokens not found in larger sentiments, such as concerns over student loan debt. Logistic regression illustrates that, depending on sentiment or communication style explored, political identities and memberships associated with source and political alignment significantly affected likelihoods of communicating in the conversation. These findings are linked back to political identity theory.     

Single service points in libraries: A review

ABSTRACT

As libraries of all types and sizes continue to re-envision themselves to remain relevant in a rapidly changing information landscape, the single service point is visible evidence of this effort. In a complex environment, combining formerly disparate functional or service units is for many libraries both an innovative and effective way to manage resources and services. It is the intent of this overview to look beyond these issues to find similarities in theme and application that may be useful for those considering implementation of a one-stop model.

Identifying and developing crosscutting environmental education outcomes for adolescents in the twenty-first century (EE21)

Abstract

While multiple valid measures exist for assessing outcomes of environmental education (EE) programs, the field lacks a comprehensive and logistically feasible common instrument that can apply across diverse programs. We describe a participatory effort for identifying and developing crosscutting outcomes for Environmental Education in the twenty-first Century (EE21). Following extensive input and debate from a wide range of EE providers and researchers, we developed, tested and statistically validated crosscutting scales for measuring consensus-based outcomes for individual participants in youth EE programs using confirmatory factor analysis across six unique sites, including two single-day field trip locations, four multiday residential programs and one science museum in the United States. The results suggest that the scales are valid and reliable for measuring outcomes that many EE programs in the United States can aspire to influence in adolescent participants, ages 10–14.     

Wrestling

The purpose of this study was to determine whether there is a significant difference in the co‐efficient of friction (Fc) between old versus new wrestling shoes and mats and to investigate the effect of perspiration. Fc was measured by dragging a weighted shoe over a wrestling mat surface and measuring the vertical and horizontal forces produced. Three different shoe conditions were assessed over two mat types for both wet and dry conditions for a total of 12 conditions. To simulate the wet condition, saline solution was smeared over the surface of the mat. There was a significant effect of shoe, mat, and wet/dry conditions. In addition, significant interactions of shoe by mat, shoe by dry/wet, and mat by dry/wet were observed. Overall, Fc was 36% higher for the new wrestling mat compared to the old wrestling mat. Application of the saline solution reduced Fc by 14% compared to the dry condition. Comparison of the mean Fc for all three shoe types revealed the Fc for the older design shoe was 23% to 28% lower than the brand new shoe and the worn newer design, respectively. A high Fc, such as in the new mat/new shoe combination, has the potential to increase the risk of knee and ankle injuries by fixing the foot more securely to the ground.     

Library as the Technology Hub for the Health Sciences

Abstract

Academic health sciences libraries have an important role in facilitating the use of technology in health sciences curricula. Serving as a technology hub, the library supports, advocates, and provides access to new technologies. The library introduces many faculty and students to new technology tools, techniques, and equipment for new multimedia creation. As the technology hub grows and expands, library personnel can provide expertise, which demonstrates the library's value in leading the exploration of new technology, including Do-It-Yourself multimedia tools, virtual reality, virtual anatomy, and 3D printing.
