Although its cause is not yet perfectly established, the pathology, often a sequel of acute otitis media (AOM, is mainly characterized by persistent fluid in the middle ear cavity. Twenty-two children with a diagnosis of SOM were treated daily for 90 days with an oral formulation containing the oral probiotic Streptococcus salivarius K12 (Bactoblis®. After treatment, the children were evaluated for AOM episodes and subjected to tone audiometry, tympanometry, endonasal endoscopy, otoscopy, and tonsillar examination. Subject compliance and probiotic tolerability and side effects have also been evaluated. Our results indicate a good safety profile, a substantial reduction of AOM episodes, and a positive outcome from the treatment for all of the clinical outcomes tested. We conclude that strain K12 may have a role in reducing the occurrence and/or severity of SOM in children. From our perspective, this study constitutes a starting point toward the organization of a more extensive placebo-controlled study aimed at critically appraising our preliminary observations.

    It has been the tradition of the libraries to support literacy. Now in the realm of Executive Order, Making Open and Machine Readable the New Default for Government Information, May 9, 2013, the library has the responsibility to support geospatial data, big data, earth science data or cyber infrastructure data that may support STEM for educational pipeline stimulation. (Such information can be found at http://www.whitehouse.gov/the-press-office/2013/05/09/executive-order-making-open-and-machine-readable-new-default-government-.) Provided is an Educational Data Curation Framework (EDCF) that has been initiated in Purdue research, geospatial data service engagement and outreach endeavors for future consideration and application to augment such data science and climate literacy needs of future global citizens. In addition, this endorsement of this framework by the GLOBE program may facilitate further EDCF implementations, discussion points and prototypes for libraries. In addition, the ECDF will support teacher-led, placed-based and large scale climate or earth science learning systems where such knowledge transfer of climate or earth science data is effectively transferred from higher education research of cyberinfrastructure use such as, NOAA or NASA, to K-12 teachers and school systems. The purpose of this effort is to establish best practices for sustainable K-12 data science delivery system or GLOBE-provided system (http://vis.globe.gov/GLOBE/) where libraries manage the data curation and data appropriateness as data reference experts for such digital data. Here, the Purdue University Libraries' GIS department works to support soils, LIDAR and water science data experiences to support teacher training for an EDCF development effort. Lastly, it should be noted that the interdisciplinary collaboration and demonstration of library supported outreach partners and national organizations such the GLOBE program may best foster EDCF development.

    Streptococcus salivarius K12 (BLIS K12) is a probiotic strain strongly antagonistic to the growth of Streptococcus pyogenes, the most important bacterial cause of pharyngeal infections in humans. Shown to colonize the oral cavity and to be safe for human use, BLIS K12 has previously been reported to reduce pharyngo-tonsillitis episodes in children or adults known to have experienced recurrent streptococcal infection. The present study was focussed upon evaluating the role of BLIS K12 in the control of streptococcal disease and acute otitis media in children attending the first year of kindergarten. By randomization, 222 enrolled children attending the first year of kindergarten were divided into a treated group (N = 111) receiving for 6 months a daily treatment with BLIS K12 (Bactoblis®) and a control group (N = 111) who were monitored as untreated controls. During the 6 months of treatment and 3 months of follow-up, the children were evaluated for treatment tolerance, and for episodes of streptococcal pharyngo-tonsillitis, scarlet fever and acute otitis media. During the 6-month trial (N = 111 per group) the incidence of streptococcal pharyngo-tonsillitis, scarlet fever and acute otitis media was approximately 16%, 9% and 44% respectively in the treated group and 48%, 4% and 80% in the control group. During the 3-months follow-up (N = 29 per group) the corresponding rates of infection were 15%, 0% and 12% in the treated group and 26%, 6% and 36% in the controls. No apparent side effects were detected in the treated group either during treatment or follow-up. All of the enrolled children completed the study. The daily administration of BLIS K12 to children attending their first year of kindergarten was associated with a significant reduction in episodes of streptococcal pharyngitis and acute otitis media. No protection against scarlet fever was detected.

    Ahmad, M; Srivastava, B S; Agarwala, S C

    1978-07-01

    The exposure of exponentially grown Escherichia coli K12 to 52 degrees C for 30 min in Tris/Mg2+ buffer resulted in a considerable loss of viability when plated on tryptone agar. When such heated bacteria were held at 37 degrees C for 2 h in tryptone broth before plating on tryptone agar, there was a significant increase in viability. Thus, heat damage was repaired in tryptone broth but not on tryptone agar. Recovery was greater in tryptone broth than in synthetic medium. In tryptone broth, recA or polA mutants also recovered but a lex mutant did not. As a result of heating, the sensitivity of bacteria to ultraviolet radiation (u.v.), to mitomycin C and to plating on high salt medium was enhanced. After incubation for 2 h in tryptone broth at 37 degrees C, the bacteria regained their resistance to u.v. and mitomycin C and tolerance to high salt medium. Recovery of viability required RNA and protein synthesis, whereas recovery of u.v. resistance did not require protein synthesis. Heating for 30 min inhibited the release of acid-soluble material from DNA in all strains of E. coli used.

  15. Effects of starvation on the transport of Escherichia coli K12 in saturated porous media are dependent on pH and ionic strength

    Xu, S.; Walczak, J. J.; Wang, L.; Bardy, S. L.; Li, J.

    2010-12-01

    In this research, we investigate the effects of starvation on the transport of E. coli K12 in saturated porous media. Particularly, we examine the relationship between such effects and the pH and ionic strength of the electrolyte solutions that were used to suspend bacterial cells. E. coli K12 (ATCC 10798) cells were cultured using either Luria-Bertani Miller (LB-Miller) broth (10 g trypton, 5 g yeast extract and 10 g NaCl in 1 L of deionized water) or LB-Luria broth (10 g tryptone, 5 g yeast extract and 0.5 g NaCl in 1 L of deionized water). Both broths had similar pH (~7.1) but differed in ionic strength (LB-Miller: ~170 mM, LB-Luria: ~ 8 mM). The bacterial cells were then harvested and suspended using one of the following electrolyte solutions: phosphate buffered saline (PBS) (pH ~7.2; ionic strength ~170 mM), 168 mM NaCl (pH ~5.7), 5% of PBS (pH ~ 7.2; ionic strength ~ 8 mM) and 8 mM NaCl (pH ~ 5.7). Column transport experiments were performed at 0, 21 and 48 hours following cell harvesting to evaluate the change in cell mobility over time under “starvation” conditions. Our results showed that 1) starvation increased the mobility of E. coli K12 cells; 2) the most significant change in mobility occurred when bacterial cells were suspended in an electrolyte solution that had different pH and ionic strength (i.e., LB-Miller culture suspended in 8 mM NaCl and LB-Luria culture suspended in 168 mM Nacl); and 3) the change in cell mobility primarily occurred within the first 21 hours. The size of the bacterial cells was measured and the surface properties (e.g., zeta potential, hydrophobicity, cell-bound protein, LPS sugar content, outer membrane protein profiles) of the bacterial cells were characterized. We found that the measured cell surface properties could not fully explain the observed changes in cell mobility caused by starvation.

    Full Text Available In this article academic librarians present and analyze a model for community building through social media. Findings demonstrate the importance of strategy and interactivity via social media for generating new connections with library users. Details of this research include successful guidelines for building community and developing engagement online with social media. By applying intentional social media practices, the researchers’ Twitter user community grew 100 percent in one year, with a corresponding 275 percent increase in user interactions. Using a community analysis approach, this research demonstrates that the principles of personality and interactivity can lead to community formation for targeted user groups. Discussion includes the strategies and research approaches that were employed to build, study, and understand user community, including user type analysis and action-object mapping. From this research a picture of the library as a member of an active academic community comes into focus.

  2. Expression of csp genes in E. coli K-12 in defined rich and defined minimal media during normal growth, and after cold-shock.

    Science.gov (United States)

    Czapski, Tiffaney R; Trun, Nancy

    2014-08-15

    Cold-shock proteins (Csps) are a family of small nucleic acid-binding proteins found in 72% of sequenced bacterial genomes. Where it has been examined, at least one csp gene is required for cell viability. In Escherichia coli K-12, there are nine homologous csp genes named A-I. Regulation studies performed on individual members of this family have suggested that cspA, cspB, cspG, and cspI are cold-induced, cspC and cspE are constitutively expressed, cspD is stationary phase induced, and the induction patterns for cspF and cspH have yet to be determined. Aside from microarray studies, transcript levels from all nine csp genes have never been assayed using the same technique or in the same cells. The purpose of this study was to use quantitative RT-PCR to establish csp expression patterns for all nine csp genes at 37°C in defined rich and defined minimal media, and after a shift to 15°C for either 1h or 4h. We found that transcript levels for each of the csp genes changed throughout the growth curve. Transcripts for cspA, -B, and -E were more abundant than those detected for the other csp genes in defined rich medium. cspE mRNA levels in defined minimal medium were drastically higher than mRNA for the other csp genes. Of the nine csp genes, only cspI showed a significant increase in mRNA accumulation after cold-shock in defined rich medium. When mRNA accumulation was compared across the nine csp genes, there were more cspE transcripts in the cell than cspA, -B, -G, or -I transcripts after 1h cold-shock in either defined rich or defined minimal media.

Unpublished observations indicate that it can also antagonize the growth of other bacteria involved in acute otitis media. Because of its ability to colonize the oral cavity and its safety profile, we have tested its efficacy in reducing the incidence of streptococcal pharyngitis and/or tonsillitis and episodes of acute otitis media.Methods: We enrolled 82 children, including 65 with and 17 without a recent diagnosis of recurrent oral streptococcal pathology. Of those with recurrent pathology, 45 were treated daily for 90 days with an oral slow-release tablet containing five billion colony-forming units of S. salivarius K12 (Bactoblis®, and the remaining 20 served as an untreated control group. The 17 children without a recent diagnosis of recurrent oral pathology were used as an additional control group. After 90 days of treatment, a 6-month follow-up period without treatment was included to evaluate a possible persistent protective role for the previously administered product.Results: The 41 children who completed the 90-day course of Bactoblis showed a reduction in their episodes of streptococcal pharyngeal infection (about 90% and/or acute otitis media (about 40%, calculated by comparing infection rates in the previous year. The 90-day treatment also reduced the reported incidence of pharyngeal and ear infections by about 65% in the 6-month follow-up period

  1. Creating Effective K-12 Outreach

    Science.gov (United States)

    Hopkins, J.

    2011-12-01

    Grant opportunities require investigators to provide 'broader impacts' for their scientific research. For most researchers this involves some kind of educational outreach for the K-12 community. I have been able to participate in many different types of grant funded science teacher professional development programs. The most valuable have been outreach where the research seamlessly integrated with my classroom curriculum and was sustainable with my future classes. To accomplish these types of programs, the investigators needed to research the K-12 community and identify several key aspects of the K-12 environment where their expertise would benefit me and my students. There are a lot of different K-12 learning environments, so researchers need to be sure to match up with the right grade level and administrative environment. You might want to consider non-main stream school settings, such as magnet programs, STEM academies, and distance learning. The goal is to try to make your outreach seem natural and productive. This presentation will illustrate how researchers can create an educational outreach project that will be a win-win situation for everyone involved.

Since Thursday 1 November, the P42 beam line of the SPS has once again been sending protons to the beryllium target to produce the K12 kaon beam line eagerly awaited by the NA62 collaboration. This was no trivial matter! The first step was to clear the decks by dismantling the entire H10 beam line and NA60 experiment, as well as most of the NA48 experiment - representing some 1000 tonnes of equipment in total! Next came the complete renovation of the infrastructure, which dated back to 1979.

  8. Optics education for K-12

    Science.gov (United States)

    Bilbro, James W.; Gaines Walker, Janice M.

    2000-06-01

    The SPIE Education Committee has developed an outreach program aimed at enhancing the dissemination of information about optics to children in kindergarten through the 12th grade (K-12). The main impetus behind the program was that more practicing optical scientists and engineers would be willing to give lectures and demonstrations aimed at inspiring the next generation about optics if material could be made easily available. Consequently, three instructional `outreach kits' were assembled to use in teaching optics to kids in exciting and fun ways. These kits were beta-tested over the last two years at six different U.S. regional sites. Each `outreach kit' contained: (1) a workbook on Optical Demonstrations on the Overhead Projector; (2) a Science and Math Experience Manual: Light, Color and Their Uses; (3) The Optics Discovery Classroom Kit; (4) a slide show; and (5) a video on careers in optics. The best tests were aimed at evaluating the practical ways of utilizing the kits, developing easy-to-follow instructions for guiding others in their use and providing suggestions on modifications, additions, and deletions to the kits. This paper discuses this outreach program and provides details relative to the kit's composition and future plans.

  14. Scholarly social media profiles and libraries: A review

    Directory of Open Access Journals (Sweden)

    Judit Ward

    2015-05-01

    Full Text Available This article aims to point out emerging roles and responsibilities for academic librarians with the potential of better integrating the library in the research process. In order to find out how to enhance the online reputation and discoverability of individual faculty members as well as their affiliated institutions, the authors worked side-by-side with researchers in the United States and Europe to explore, create, revise, and disambiguate scholarly profiles in various software applications. In an attempt to understand and organize scholarly social media, including new, alternative metrics, the authors reviewed and classified the major academic profile platforms, highlighting the overlapping elements, benefits, and drawbacks inherent in each. The consensus is that it would be time-consuming to keep one’s profile current and accurate on all of these platforms, given the plethora of underlying problems, also discussed in detail in the article. However, it came as a startling discovery that reluctance to engage with scholarly social media may cause a misrepresentation of a researcher’s academic achievements and may come with unforeseen consequences. The authors claim that current skills and competencies can secure an essential role for academic librarians in the research workflow by means of monitoring and navigating researcher profiles in scholarly social media in order to best represent the scholarship of their host institutions.

There are several things that can be done by the school in order to change the social stigma of the existence of the school. First, the library should be managed more professional. Second, the library should be developed with adequate facilities. Based on the role and duties of the library, the library needs to conduct educational programs or users so that the available library collection can be disseminated and used effectively and efficiently.

    2013-04-01

    The Soil Science Society of America created its K12 Committee in 2006 in part to compliment the Dig It! The Secrets of Soil exhibit that opened in July 2008 at the Smithsonian's Institution's Nation Museum of Natural History (of which SSS was a founding sponsor). The committee's work began quickly with a website designed to provide resources for K12 teachers. The first accomplishments included reviewing and posting links to web based information already available to teachers. These links were sorted by subject and grade level to make it easier for teachers to navigate the web and find what they needed quickly. Several presentations and lessons designed for K12 teachers were also posted at this time. Concurrent with this effort a subcommittee review and organized the national teaching standards to show where soils could fit into the overall K12 curriculum. As the website was being developed another subcommittee developed a soils book (Soil! Get the Inside Scoop, 2008) to further compliment the Dig It! exhibit. This was a new endeavor for SSSA having never worked with the non-academic audience in developing a book. Peer-reviews of this book included not only scientist but also students in order to make sure the book was attractive to them. Once the book was published and the website developed it became clear more outreach was needed. SSSA K12 Committee has attended both the National Science Teachers Association (since 2008) the USA Science and Engineering Festival (since 2010) with exhibits and workshops. It has cooperated and contributed to the American Geologic Institutes' Earth Science Week materials with brochures and lesson plans and with National Association of Conservation Districts by providing peer-review and distribution of materials. The most recent developments from the committee include a web redesign that is more student and teacher friendly, the development of a peer-review system to publish K12 Lesson Plans, and finally the publication of a new soils

    Robigou, V.

    2004-12-01

    The publication of countless reports documenting the dismal state of science education in the 1980s, and the Third International Mathematics and Science Study (TIMMS) report (1996) called for a wider involvement of the scientific community in K-12 education and outreach. Improving science education will not happen without the collaboration of educators and scientists working in a coordinated manner and it requires a long-term, continuous effort. To contribute effectively to K-12 education all scientists should refer to the National Science Education Standards, a set of policies that guide the development of curriculum and assessment. Ocean scientists can also specifically refer to the COSEE recommendations (www.cosee.org) that led to the creation of seven regional Centers for Ocean Sciences Education Excellence. Scientists can get involved in K-12 education in a multitude of ways. They should select projects that will accommodate time away from their research and teaching obligations, their talent, and their interest but also contribute to the education reform. A few examples of effective involvement are: 1) collaborating with colleagues in a school of education that can lead to better education of all students and future teachers, 2) acting as a resource for a national program or a local science fair, 3) serving on the advisory board of a program that develops educational material, 4) speaking out at professional meetings about the value of scientists' involvement in education, 5) speaking enthusiastically about the teaching profession. Improving science education in addition to research can seem a large, overwhelming task for scientists. As a result, focusing on projects that will fit the scientist's needs as well as benefit the science reform is of prime importance. It takes an enormous amount of work and financial and personnel resources to start a new program with measurable impact on students. So, finding the right opportunity is a priority, and stepping

    2013-03-01

    Engineers rely on physicists as well as other scientists and mathematicians to explain the world in which we live. Engineers take this knowledge of the world and use it to create the world that never was. The teaching of physics and other sciences as well as mathematics is critical to maintaining our national workforce. Science and mathematics education are inherently different, however, from engineering education. Engineering educators seek to enable students to develop the habits of mind critical for innovation. Through understanding of the engineering design process and how it differs from the scientific method, students can apply problem and project based learning to solve the challenges facing society today. In this talk, I will discuss the elements critical to a solid K-12 engineering education that integrates science and mathematics to solve challenges throughout the world.

    2014-01-01

    We have collected and analyzed the relevant data from public schools in greater Houston area of Texas. Based and analyzed. Since the data is only limited to a few school, we are still working on getting more data so that we can compare and contrast the results adequately and understand the core of the enrollment issue at the national level. However, based on the raw data and partial analysis, we propose a few recommendations towards the improvement of science education in Texas Schools, in general, and greater Houston area schools in particular. Our results indicate that the quality of science education can be improved significantly if we focus on the improvement of high school education or even intermediate schools when students are first time exposed to science in a little technical way. Simply organizing teacher training programs at K-12 level as school education plays a pivotal role in the decrease in physics enrollment at the higher level. Similar analysis can actually be generalized to other states to f...

  10. Supporting Geoscientists in Partnerships for K-12 Education at NSF

    Leinen, M.

    2001-12-01

    NSF Directorate for Geosciences (GEO) education activities have evolved over the last decade based on advice from a broad segment of the geosciences community. These activities gained momentum when a Geosciences Education Working Group (GEWG, 1996) recognized the shift from traditional priorities that emphasized only research, to those that support education in geosciences as well. The GEWG report embraced this increased emphasis on education as a component of NSF's role in assuring the long-term health of the geosciences and endorsed the principle that research and education should be well integrated. While many geosciences education activities are funded by the Education and Human Resources Directorate (EHR) of NSF, the GEWG report highlighted the need to have more active participation by research geoscientists in K-12 education activities, and the need to train them to be able to do so. While some roles in education are clearly best left to educational professionals (e.g. large-scale systemic reform projects, pedagogical development at the K-12 level, and many teacher enhancement projects), activities such as undergraduate research, technology advancement, curriculum content development and informal science are ones in which GEO should actively seek to collaborate with programs in EHR. The GEO education program has expanded over the last decade. Our first education activity, Awards to Facilitate Geoscience Education (AFGE), was very successful in attracting some of the leading researchers in geosciences. This program evolved to become the Geoscience Education Program. An important program funded by GEO that developed from community activity is the Digital Library for Earth System Education (DLESE). This program grew out of a joint EHR/GEO award and a series of community workshops. The program will establish an Internet portal for geoscience curricular materials and other teacher resources that will enable further collaboration between the research and education

  12. Social media in times of libraries 2.0: A study into the Brazilian Federal Education instituitions’ libraries bringing future perspectives for digital preservation

    Directory of Open Access Journals (Sweden)

    Laura Vilela Rodriges Rezende

    2016-09-01

    Full Text Available This study aims to discuss the main challenges regarding the social participation on the Web by the Brazilian Federal Education Institutions’(IFES Libraries and the changes related to the these institutions’ activities, especially interactions with their audience. The Research conducted a quantitative approach survey on the use of the main existing social media by these libraries. The survey sought to identify the level of involvement and participation of these libraries in social media. It is understood that this investigation is necessary as a foundation to the urgent need to raise awareness these Brazilian institutions as the valuable potential of interaction with their users through these media, despite the study demonstrated an incipient use. Based on the conducted survey, the study presents a reflection of the importance that it should devote to digital preservation, not only of their collections, but also the relevant records of the social media content. The results show that most brazilian public universities use Web 2.0 tools with social focus, and the greater adoption of Facebook (43% and Twitter (29%, but only 5% of them use these medias to disseminate the collections. Thus, it was concluded that the use of social media by these libraries still have a lot to develop and consequently the digital preservation actions need to consider the inclusion of content generated by these media that increasingly have become a valuable communication channel.

  13. Media discourse on Split reading rooms and libraries in Dalmatian periodicals (1862 - 1918

    Directory of Open Access Journals (Sweden)

    Ivanka Kuić

    2013-03-01

    Full Text Available The paper focuses on the media discourse on reading rooms and libraries as a historical phenomenon that describes the role and place of reading rooms and libraries in Dalmatia in the 60ties of the 19th century and World War I. The papers in Dalmatian newspapers from that period, as materialized forms of discourse, answer many important questions related to the history of Croatian librarianship: how were the reading rooms and libraries established and what crucial concept determined their role and place in a particular period in history. The paper presents the historical concept, conditions in which the discourse occurred, discourse types and functions, conceptual structure, and transformation processes towards new discourse practices. The discourse analysis has shown that the reading rooms and libraries are cultural artifacts strongly influenced by the social context. Two stages in the development of discourse have been identified: in the first stage the discourse takes a considerable role in metaphorical games and construction of mythical structures - ethnic identity, national unity and language community. On the conceptual level the role of reading rooms and libraries is recognized in the deconstruction of traditional relations - they are a territorially separate, exclusive place of symbolic production, creation of new social structures and cultural values. In that context, the activities of libraries are underrepresented compared to other activities of reading rooms. The second stage, which started in the 90ies of the 19th century, is marked by discourse multiplication, differentiation of library organization structure and function from other functions of culture, and the strong influence of new discourse. The media discourse presents the change of conceptual structures, in which the role and place of libraries is interpreted in the context of the role of knowledge and education in meeting society goals in the situation of social

    2017-03-01

    Full Text Available Objective: The main objective of the paper is to study the presence of Iranian Information Science & Library Science articles in social media websites and tools. Articles with the highest altmetric scores will be identified and the association between altmetric and citation indicators will be investigated. Methodology: This study is an applied research using altmetric data. A total of 563 articles in the area of Information Science & Library Science which specified Iran as their affiliated country and indexed by the Thomson Reuters until the end of 2014, were selected as the population of study. The altmetric bookmarklet, a service provided by Altmetric Institute was used for data collection. Statistical analysis and visualization was conducted using R statistical computing software. Results: Out of 563 Iranian IS & LS articles, 72 papers (12.8% were mentioned at least once in different social media. Twitter (80.55% stands out as the most promising altmetric source for Iranian IS & LS papers, followed by Mendeley (77.77% and CiteULike (22.22%. Studying the share of IS & LS papers with altmetric indicators across publication years show that papers published in 2014 have the highest proportion (30%. The results of running a Spearman correlation test revealed statistically significant but moderate relationships between Mendeley and CiteULike readership counts and number of citations in Web of Science. Conclusion: Altmetric indicators, indices based on activity in social media environments, have the potential to measure scientific impact of researchers beside other scientometric indicators.

  2. Streptococcus salivarius K12 Limits Group B Streptococcus Vaginal Colonization.

    Streptococcus agalactiae (group B streptococcus [GBS]) colonizes the rectovaginal tract in 20% to 30% of women and during pregnancy can be transmitted to the newborn, causing severe invasive disease. Current routine screening and antibiotic prophylaxis have fallen short of complete prevention of GBS transmission, and GBS remains a leading cause of neonatal infection. We have investigated the ability of Streptococcus salivarius, a predominant member of the native human oral microbiota, to control GBS colonization. Comparison of the antibacterial activities of multiple S. salivarius strains by use of a deferred-antagonism test showed that S. salivarius strain K12 exhibited the broadest spectrum of activity against GBS. K12 effectively inhibited all GBS strains tested, including disease-implicated isolates from newborns and colonizing isolates from the vaginal tract of pregnant women. Inhibition was dependent on the presence of megaplasmid pSsal-K12, which encodes the bacteriocins salivaricin A and salivaricin B; however, in coculture experiments, GBS growth was impeded by K12 independently of the megaplasmid. We also demonstrated that K12 adheres to and invades human vaginal epithelial cells at levels comparable to GBS. Inhibitory activity of K12 was examined in vivo using a mouse model of GBS vaginal colonization. Mice colonized with GBS were treated vaginally with K12. K12 administration significantly reduced GBS vaginal colonization in comparison to nontreated controls, and this effect was partially dependent on the K12 megaplasmid. Our results suggest that K12 may have potential as a preventative therapy to control GBS vaginal colonization and thereby prevent its transmission to the neonate during pregnancy.

    Geoffrey; Z.LIU; Yan; HUO

    2012-01-01

    Purpose:Given the unique characteristics of physical education(PE) teaching in K-12education,PE teachers’ information behaviors deserve special attention.This article reports a survey study of PE teachers’ information behaviors,covering information literacy skills and behaviors of information seeking and information use.Design/methodology/approach:A questionnaire survey was conducted of K-12 PE teachers in the Tianjin municipal region of China,with a response rate of 61.9%.Findings:PE teachers lack skills with information retrieval systems in general.The Internet continues to be their primary information source,and they rely more on personal collection and colleagues than the school library for teaching materials.They rarely develop a searching strategy,employ querying tactics,or use advanced search functions,and they tend to be content with finding a few relevant articles.Research limitations:The survey is limited to the Tianjin municipal region in scope.Though attempting to reach 210 participants from 40 schools,it yielded only 130 valid responses.A larger survey covering more regions and with greater responses may be useful.Practical implications:Insights from this study inform the educational and on-job training of K-12 PE teachers to improve their information literacy skills.Originality/value:Little research exists on PE teachers’ behaviors of information seeking.This study bridges the gap and enriches our understanding of K-12 teachers’ information behaviors.

    Traditionally, probiotics are linked to the good health of the intestine and most clinical studies focus on that field. Evidence of oral probiotic use for ear and oral cavity disease prevention with impact on human health is limited. This work reviews existing studies and literature on Streptococcus salivarius K12 as an oral probiotic and effects of S. salivarius K12 on human ear and oral cavity human health. The studies were accessed via database searches: MEDLINE, PubMed, and Elsevier. The search included/focused on/encompassed publications from 2003 to 2016 with keywords related to K12 Streptococcus salivarius, bacteriocin-like inhibitory substances (BLIS) K12, probiotic K12 salivarius, and K12 probiotic health effects. Only a small amount of studies was identified: the total of 68 studies was identified, 35 of which were relevant after screening, and 9 were included in the final analysis. Very little literature is available about the association/correlation between/connection/interrelation of S. salivarius K12 with/and human ear and oral cavity health. S. salivarius K12 may have a role in reducing the occurrence and/or severity of secretory otitis media (SOM) and also in prevention of streptococcal and viral pharyngotonsillitis in children. Research highlights that S. salivarius K12 has shown promising results in treatment of halitosis, but data are still deficient. Further studies need to be initiated to improve understanding of the association of oral probiotic S. salivarius K12 with human ear and oral cavity health.

    2011-01-01

    Librarians at the Mayo Clinic developed customized Web 2.0 courses for library staff, health science faculty, and nurse educators. As demand for this type of training spread across the institution, a single, self-paced class was developed for all employees. The content covered the typical Web 2.0 and social media tools (e.g., blogs, really simple syndication [RSS], wikis, social networking tools) emphasizing the organization's social media guidelines. The team consulted with the public affairs department to develop the class and coordinate marketing and advertising. The eight-module, blog-based course was introduced to all employees in 2010. Employees completing each module and passing a brief assessment receive credit on their employee transcript. Libraries staff provided support to participants throughout the duration of the course through chat widgets, e-mail, and blog comments. The results show that even though a high number of learners accessed the course, the completion percentage was low since there was no requirement to complete the course. Deploying a single, self-paced course for a large institution is an enormous undertaking, requiring the support of high level administration, managers, and employees.

  6. Undergraduate interest in K--12 teaching and the perceived 'climate' for the K--12 education profession in the natural sciences

    Science.gov (United States)

    Gerdeman, Robert Dean

    Previous research suggests that the natural science setting in universities does not offer a supportive environment for undergraduates interested in K--12 education careers, an important problem given the need for K--12 science teachers. A mixed-method approach was used to examine student perspectives toward K--12 education careers, and the influence of the college experience on perspectives, at a public research university. Quantitative data come from a cross-sectional survey sample (N = 444) of upper-division natural science majors in the university. The survey focused on student background characteristics, undergraduate experiences, perceptions of the college environment, career interests, and satisfaction. Pursuit of K--12 education as a top current career choice was rare among the respondents (3.6%). However, about one-fourth of them indicated some interest in this career and overall interest increased slightly during the college experience. Based on student perceptions, K--12 education was substantially less emphasized within the natural sciences than other career fields. Regression analyses revealed that the most important predictors (aside from initial career interests) of interest in and attitude toward K--12 teaching were self-concept and personality measures. Several college experience measures were also predictors, including perceptions about faculty and peers in the natural sciences. The effect of college experiences differed for students initially more inclined toward K--12 teaching, who reported a net decrease in interest, versus those more disinclined, who reported a net gain in interest. Satisfaction with the college experience was similar for the two groups. Qualitative data come from follow-up interviews conducted with eight survey respondents who recalled a top choice of K--12 teaching upon entering college but had decided to pursue another career. These students perceived other career fields to offer better professional opportunities for

    K-12 educators need effective and relevant astronomy professional development. NASA's Mission Science provides innovative and accessible opportunities for K-12 teachers. Science questions involve scale and distance, including Moon/Earth scale, solar system scale, and distance of objects in the universe. Teachers can gain an understanding of basic telescopes, the history of telescopes, ground and satellite based telescopes, and models of JWST Telescope. An in-depth explanation of JWST and Spitzer telescopes gave participants background knowledge for infrared astronomy observations. During teacher training, we taught the electromagnetic spectrum through interactive stations. The stations included an overview via lecture and power point, the use of ultraviolet beads to determine ultraviolet exposure, the study of lenticulars and diagramming of infrared data, looking at visible light through diffraction glasses and diagramming the data, protocols for using astronomy based research in the classroom, and infrared thermometers to compare environmental conditions around the observatory. An overview of LIDAR physics was followed up by a simulated LIDAR mapping of the topography of Mars.We will outline specific steps for K-12 infrared astronomy professional development, provide data demonstrating the impact of the above professional development on educator understanding and classroom use, and detail future plans for additional K-12 professional development.Funding was provided by Washington STEM, NASA, and the Washington Space Grant Consortium.

    Robeck, E.

    2016-12-01

    The same scientific visualizations, animations, and images that are powerful tools for geoscientists can serve an important role in K-12 geoscience education by encouraging students to communicate in ways that help them develop habits of thought that are similar to those used by scientists. Resources such as those created by NASA's Scientific Visualization Studio (SVS), which are intended to inform researchers and the public about NASA missions, can be used in classrooms to promote thoughtful, engaged learning. Instructional materials that make use of those visualizations have been developed and are being used in K-12 classrooms in ways that demonstrate the vitality of the geosciences. For example, the Center for Geoscience and Society at the American Geosciences Institute (AGI) helped to develop a publication that outlines an inquiry-based approach to introducing students to the interpretation of scientific visualizations, even when they have had little to no prior experience with such media. To facilitate these uses, the SVS team worked with Center staff and others to adapt the visualizations, primarily by removing most of the labels and annotations. Engaging with these visually compelling resources serves as an invitation for students to ask questions, interpret data, draw conclusions, and make use of other processes that are key components of scientific thought. This presentation will share specific resources for K-12 teaching (all of which are available online, from NASA, and/or from AGI), as well as the instructional principles that they incorporate.

    Can professional engineers, mathematicians, and scientists have a positive impact on K-12 math and science education? The experience of the Santa Fe Alliance for Science, and several other like-minded organizations, indicates that they can indeed. But success is by no means assured. Good scientists are not automatically good educators, but they can learn enough about pedagogy, classroom, and community to do well. For example, their experiences working on research topics of great societal interest (e.g. the energy supply or global warming) can be a great attraction to young people. This discussion will be oriented around three major points: lessons learned, prospects for the future, and how our effort fits into state-wide plans for re-inventing K-12 math and science education in New Mexico.

    2016-08-26

    A simulation-based technical feasibility study was completed to show the types of technologies required to achieve ZEB status with this building type. These technologies are prioritized across the building's subsystem such that design teams can readily integrate the ideas. Energy use intensity (EUI) targets were established for U.S. climate zones such that K-12 schools can be zero-ready or can procure solar panels or other renewable energy production sources to meet the zero energy building definition. Results showed that it is possible for K-12 schools to achieve zero energy when the EUI is between 20 and 26 kBtu/ft2/yr. Temperate climates required a smaller percentage of solar panel coverage than very hot or very cold climates. The paper provides a foundation for technically achieving zero energy schools with a vision of transforming the school construction market to mainstream zero energy buildings within typical construction budgets.

    The Science Teacher Education Program (STEP) offered a unique framework for creating professional development courses focused on Arctic research from 2006-2009. Under the STEP framework, science, technology, engineering, and math (STEM) training was delivered by teams of practicing Arctic researchers in partnership with master teachers with 20+ years experience teaching STEM content in K-12 classrooms. Courses based on the framework were offered to educators across Alaska. STEP offered in-person summer-intensive institutes and follow-on audio-conferenced field-test courses during the academic year, supplemented by online scientist mentorship for teachers. During STEP courses, teams of scientists offered in-depth STEM content instruction at the graduate level for teachers of all grade levels. STEP graduate-level training culminated in the translation of information and data learned from Arctic scientists into standard-aligned lessons designed for immediate use in K-12 classrooms. This presentation will focus on research that explored the question: To what degree was scientist involvement beneficial to teacher training and to what degree was STEP scientist involvement beneficial to scientist instructors? Data sources reveal consistently high levels of ongoing (4 year) scientist and teacher participation; high STEM content learning outcomes for teachers; high STEM content learning outcomes for students; high ratings of STEP courses by scientists and teachers; and a discussion of the reasons scientists indicate they benefited from STEP involvement. Analyses of open-ended comments by teachers and scientists support and clarify these findings. A grounded theory approach was used to analyze teacher and scientist qualitative feedback. Comments were coded and patterns analyzed in three databases. The vast majority of teacher open-ended comments indicate that STEP involvement improved K-12 STEM classroom instruction, and the vast majority of scientist open-ended comments

Journal of the Canadian Health Libraries Association, 37(1, 6-11. http://dx.doi.org/10.5596/c16-009 Abstract Objective – To analyze article sharing requests for health sciences literature on Twitter, received through the #icanhazpdf protocol. Design – Social media content analysis. Setting – Twitter. Subjects – 302 tweets requesting health sciences articles with the #icanhazpdf tag. Methods – The authors used a subscription service called RowFeeder to collect public tweets posted with the hashtag #icanhazpdf between February and April 2015. Rowfeeder recorded the Twitter user name, location, date and time, URL, and content of the tweet. The authors excluded all retweets and then each reviewed one of two sets. They recorded the geographic region and affiliation of the requestor, whether the tweet was a request or comment, type of material requested, how the item was identified, and if the subject of the request was health or non-health. Health requests were further classified using the Scopus subject category of the journal. A journal could be classified with more than one category. Any uncertainties during the coding process were resolved by both authors reviewing the tweet and reaching a consensus. Main results – After excluding all the retweets and comments, 1079 tweets were coded as heath or non-health related. A final set of 302 health related requests were further analyzed. Almost all the requests were for journal articles (99%, n=300. The highest-ranking subject was medicine (64.9%, n=196, and the lowest was dentistry (0.3%, n=1. The most common article identifier was a link to the publisher’s website (50%, n=152, followed by a link to the PubMed record (22%, n=67. Articles were also identified by citation information (11%, n=32, DOI (5%, n=14, a direct request to an individual (3%, n=9, another method

    Streptococcus salivarius K12 (BLIS K12(®)) is a probiotic strain producing the bacteriocins salivaricin A2 and salivaricin B, both of which strongly antagonize the growth of Streptococcus pyogenes, the most important bacterial cause of pharyngeal infections in humans. It successfully colonizes and exhibits persistence in the oral cavity and is endowed with an excellent safety profile. Previous observations of a small group of children indicated that the use of BLIS K12 could also reduce the occurrence of viral pharyngitis. The present study focused on a further evaluation of the role of BLIS K12 in the control of pediatric streptococcal disease and moreover whether its use could also help provide protection against various nonstreptococcal infections. In total, 48 children with a recent history of recurrent pharyngeal streptococcal disease were enrolled in the treated group. The control group comprised 76 children known to have had a very low recent occurrence of oral streptococcal disease. The treated children were given BLIS K12 daily for 90 days. The number of episodes of streptococcal pharyngotonsillitis, tracheitis, viral pharyngitis, rhinitis, flu, laryngitis, acute otitis media, enteritis, and stomatitis was recorded during probiotic treatment and for a follow-up period of 9 months, and this was compared with the episodes of the control group over the corresponding period. Compared with the pretreatment time period, 2013, a 90% reduction of streptococcal pharyngeal disease was observed in 2014; compared with untreated children, a statistically significant reduction of all of the other disease conditions assessed, other than stomatitis, was detected in the probiotic-treated children. In agreement with previous findings, in the present study, it was found that the daily use of BLIS K12 has been associated with a concurrent and persisting reduction in the occurrence of pharyngeal, recurrent, streptococcal disease. Moreover, the benefits to children may also

    K-12 educators need effective and relevant astronomy professional development. WISE Telescope (Wide-Field Infrared Survey Explorer) and Spitzer Space Telescope Education programs provided an immersive teacher professional development workshop at Arecibo Observatory in Puerto Rico during the summer of 2009. As many common misconceptions involve scale and distance, teachers worked with Moon/Earth scale, solar system scale, and distance of objects in the universe. Teachers built and used basic telescopes, learned about the history of telescopes, explored ground and satellite based telescopes, and explored and worked on models of WISE Telescope. An in-depth explanation of WISE and Spitzer telescopes gave participants background knowledge for infrared astronomy observations. We taught the electromagnetic spectrum through interactive stations. The stations included an overview via lecture and power point, the use of ultraviolet beads to determine ultraviolet exposure, the study of WISE lenticulars and diagramming of infrared data, listening to light by using speakers hooked up to photoreceptor cells, looking at visible light through diffraction glasses and diagramming the data, protocols for using astronomy based research in the classroom, and infrared thermometers to compare environmental conditions around the observatory. An overview of LIDAR physics was followed up by a simulated LIDAR mapping of the topography of Mars. We will outline specific steps for K-12 infrared astronomy professional development, provide data demonstrating the impact of the above professional development on educator understanding and classroom use, and detail future plans for additional K-12 professional development. Funding was provided by WISE Telescope, Spitzer Space Telescope, Starbucks, Arecibo Observatory, the American Institute of Aeronautics and Astronautics, and the Washington Space Grant Consortium.

    Educator Academy is a K-12 STEM curriculum developed by the STEM K-12 Outreach Committee of the American Institute of Aeronautics and Astronautics (AIAA). Consisting of three independent curriculum modules, K-12 students participate in inquiry-based engineering challenges to improve critical thinking skills and enhance problem solving skills. The Mars Rover Celebration Curriculum Module is designed for students in grades 3-8. Throughout this module, students learn about Mars and the solar system. Working with given design criteria, students work in teams to do basic research about Mars that will determine the operational objectives and structural features of their rover. Then, students participate in the design and construction of a model of a mock-up Mars Rover to carry out a specific science mission on the surface of Mars. At the end of this project, students have the opportunity to participate in a regional capstone event where students share their rover designs and what they have learned. The Electric Cargo Plan Curriculum Module is designed for students in grades 6-12. Throughout this module, students learn about aerodynamics and the four forces of flight. Working individually or in teams, students design and construct an electrically-powered model aircraft to fly a tethered flight of at least one lap without cargo, followed by a second tethered flight of one lap carrying as much cargo as possible. At the end of this project, students have the opportunity to participate in a regional capstone event where students share what they have learned and compete with their different cargo plane designs. The Space Weather Balloon Curriculum Module is designed for students in grades 9-12. Throughout this module, students learn and refine physics concepts as well as experimental research skills. Students participate in project-based learning that is experimental in nature. Students are engaged with the world around them as they collaborate to launch a high altitude

    Full Text Available Abstract Background Escherichia coli is the model organism for which our knowledge of its regulatory network is the most extensive. Over the last few years, our project has been collecting and curating the literature concerning E. coli transcription initiation and operons, providing in both the RegulonDB and EcoCyc databases the largest electronically encoded network available. A paper published recently by Ma et al. (2004 showed several differences in the versions of the network present in these two databases. Discrepancies have been corrected, annotations from this and other groups (Shen-Orr et al., 2002 have been added, making the RegulonDB and EcoCyc databases the largest comprehensive and constantly curated regulatory network of E. coli K-12. Results Several groups have been using these curated data as part of their bioinformatics and systems biology projects, in combination with external data obtained from other sources, thus enlarging the dataset initially obtained from either RegulonDB or EcoCyc of the E. coli K12 regulatory network. We kindly obtained from the groups of Uri Alon and Hong-Wu Ma the interactions they have added to enrich their public versions of the E. coli regulatory network. These were used to search for original references and curate them with the same standards we use regularly, adding in several cases the original references (instead of reviews or missing references, as well as adding the corresponding experimental evidence codes. We also corrected all discrepancies in the two databases available as explained below. Conclusion One hundred and fifty new interactions have been added to our databases as a result of this specific curation effort, in addition to those added as a result of our continuous curation work. RegulonDB gene names are now based on those of EcoCyc to avoid confusion due to gene names and synonyms, and the public releases of RegulonDB and EcoCyc are henceforth synchronized to avoid confusion due to

    1994-12-31

    Science education has experienced significant changes over the past two decades. Science is now vital to good citizenship, performance in the workplace, and everyday life.It is time to re-tool and re-design the entire K-12 science education system, employing the same principles and methods used in the practice of science itself. We can no longer ignore the special needs of science instruction. All students need a course that develops their scientific literacy and critical thinking skills every year. Each science program needs meaningful, useful content and skill standards to drive and continuously update the curriculum content and enabel usefull assessment. Science teachers must articulate their needs and develop opportunities for professional development and the strengthening of their profession. We need a national plan that gets the many different participants working coherently towards a common goal.

    Most scientists and engineers are accustomed to presenting their research to colleagues or lecturing college or graduate students. But if asked to speak in front of a classroom full of elementary school or junior high school students, many feel less comfortable. TERC, as part of its work with The Center for Ocean Sciences Education Excellence-New England (COSEE-NE) has designed a workshop to help ocean scientists and engineers develop skills for working with K-12 teachers and students. We call this program: Telling Your Story (TYS). TYS has been offered 4 times over 18 months for a total audience of approximately 50 ocean scientists. We will discuss the rationale for the program, the program outline, outcomes, and what we have learned. ne.net/edu_project_3/index.php

  19. Test Of Astronomy STandards TOAST Survey of K-12 Teachers

    2015-01-01

    Discipline-based education research in astronomy is focused on understanding the underlying mental mechanisms used by students when learning astronomy and teachers when teaching astronomy. Systematic surveys of K-12 teacher' knowledge in the domain of astronomy are conducted periodically in order to better focus and improve professional development. These surveys are most often done when doing contemporary needs assessments or when new assessment instruments are readily available. Designed by Stephanie J. Slater of the CAPER Center for Astronomy & Physics Education Research, the 29-item multiple-choice format Test Of Astronomy STandards - TOAST is a carefully constructed, criterion-referenced instrument constructed upon a solid list of clearly articulated and widely agreed upon learning objectives. The targeted learning concepts tightly align with the consensus learning goals stated by the American Astronomical Society - Chair's Conference on ASTRO 101, the American Association of the Advancement of Science's Project 2061 Benchmarks, and the National Research Council's 1996 National Science Education Standards. Without modification, the TOAST is also aligned with the significantly less ambitious 2013 Next Generation Science Standards created by Achieve, Inc., under the auspices of the National Research Council. This latest survey reveals that K-12 teachers still hold many of the same fundamental misconceptions uncovered by earlier surveys. This includes misconceptions about the size, scale, and structure of the cosmos as well as misconceptions about the nature of physical processes at work in astronomy. This suggests that professional development in astronomy is still needed and that modern curriculum materials are best served if they provide substantial support for implementation.

    2009-01-01

    The purpose of this study is to present a library of analytical solutions for the three-dimensional contam-inant transport in uniform flow field in porous media with the first-order decay, linear sorption, and zero-order pro-duction. The library is constructed using Green's function method (GFM) in combination with available solutions.The library covers a wide range of solutions for various conditions. The aquifer can be vertically finite, semi-infin-itive or infinitive, and laterally semi-infinitive or infinitive.The geometry of the sources can be of point, line, plane or volumetric body; and the source release can be continuous,instantaneous, or by following a given function over time.Dimensionless forms of the solutions are also proposed. A computer code FlowCAS is developed to calculate the solutions. Calculated results demonstrate the correctness of the presented solutions. The library is widely applicable to solve contaminant transport problems of one- or multiple- dimensions in uniform flow fields.

    Background Streptococcus salivarius K12 is an oral probiotic strain releasing two lantibiotics (salivaricin A2 and salivaricin B) that antagonize the growth of S. pyogenes, the most important bacterial cause of pharyngeal infections in humans also affected by episodes of acute otitis media. S. salivarius K12 successfully colonizes the oral cavity, and is endowed with an excellent safety profile. We tested its preventive role in reducing the incidence of both streptococcal and viral pharyngitis and/or tonsillitis in children. Materials and methods We enrolled 61 children with a diagnosis of recurrent oral streptococcal disorders. Thirty-one of them were enrolled to be treated daily for 90 days with a slow-release tablet for oral use, containing no less than 1 billion colony-forming units/tablet of S. salivarius K12 (Bactoblis®), and the remaining 30 served as the untreated control group. During treatment, they were all examined for streptococcal infection. Twenty children (ten per group) were also assessed in terms of viral infection. Secondary end points in both groups were the number of days under antibiotic and antipyretic therapy and the number of days off school (children) and off work (parents). Results The 30 children who completed the 90-day trial with Bactoblis® showed a significant reduction in their episodes of streptococcal pharyngeal infection (>90%), as calculated by comparing the infection rates of the previous year. No difference was observed in the control group. The treated group showed a significant decrease in the incidence (80%) of oral viral infections. Again, there was no difference in the control group. With regard to secondary end points, the number of days under antibiotic treatment of the treated and control groups were 30 and 900 respectively, days under antipyretic treatment 16 and 228, days of absence from school 16 and 228, and days of absence from work 16 and 228. The product was well tolerated by the subjects, with no side effects

It successfully colonizes and exhibits persistence in the oral cavity and is endowed with an excellent safety profile. Previous observations of a small group of children indicated that the use of BLIS K12 could also reduce the occurrence of viral pharyngitis. The present study focused on a further evaluation of the role of BLIS K12 in the control of pediatric streptococcal disease and moreover whether its use could also help provide protection against various nonstreptococcal infections. Methods: In total, 48 children with a recent history of recurrent pharyngeal streptococcal disease were enrolled in the treated group. The control group comprised 76 children known to have had a very low recent occurrence of oral streptococcal disease. The treated children were given BLIS K12 daily for 90 days. The number of episodes of streptococcal pharyngotonsillitis, tracheitis, viral pharyngitis, rhinitis, flu, laryngitis, acute otitis media, enteritis, and stomatitis was recorded during probiotic treatment and for a follow-up period of 9 months, and this was compared with the episodes of the control group over the corresponding period. Results: Compared with the pretreatment time period, 2013, a 90% reduction of streptococcal pharyngeal disease was observed in 2014; compared with untreated children, a statistically significant reduction of all of the other disease conditions assessed, other than stomatitis, was detected

    2012-12-01

    As part of the Long Term Ecological Research (LTER) program, the Harvard Forest in Petersham, Massachusetts seeks to train the next generation of researchers, by involving K-12 grade students and their teachers in hands-on, field-based, ecological research in their own schoolyard and community. Students learn to collect data on important long-term ecological issues and processes. Student data are then shared on the Harvard Forest website. To prepare teachers for project protocols, teachers are given direct access to Harvard ecologists with professional development workshops and on-line resources. With the Harvard Forest Schoolyard LTER program, students can participate in three different research projects focusing on phenology, invasive insects, and vernal pools. Teachers attend the Summer Institute for Teachers to learn project content and methods. They return in fall to participate in one of three levels of data workshops to learn how to input, manage, and analyze project data. In the spring, teachers again meet with the Harvard ecologists about project protocols, and to share, through a series of teacher presentations, the ways these project themes are being integrated into class curricula. These professional development opportunities result in long term collaborative partnerships with local schools and the Harvard Forest LTER. In addition to the LTER Schoolyard Ecology Program, the Harvard Forest has supported a successful Research Experience for Teachers (RET) program for the last six years. Throughout the summer, teachers work on research projects alongside Harvard Forest and affiliated scientists, post-docs, graduate students, and REU's (Research Experience for Undergraduates). The RET program provides teachers with the opportunity to build scientific knowledge, develop an understanding of research methods, and translate their new knowledge and experiences into cutting edge classroom lessons. The past two summers I have worked with Dr. Andrew Richardson

    Full Text Available Objective – This study explored links between school libraries and student learning outcomes that were defined in a multidimensional context, using data provided by the students themselves. The researchers examined learning outcomes that reached beyond the existing correlations of school library services and standardized test scores. Insight was provided into the interactions between students and school libraries that affect student learning. An overarching goal of the study was to establish ongoing dialogue to focus on evidence based practices that may lead to continuous improvement in school library services and to provide the basis for further research.Design – Web based survey.Subjects – Participants were 13,123 students in grades 3‐12 and 879 faculty at 39 schools across the state.Setting – Ohio Public school libraries.Methods – Thirty‐nine effective school libraries, staffed by credentialed school librarians, were chosen through a judgment sampling process, using criteria based on Ohio Guidelines for Effective School Library Media Programs. The guidelines are aligned to academic content standards, assessments, resources, and professional development. Two web based surveys were used to collect quantitative and qualitative data from students and faculty: 1. The Impacts on Learning Survey, composed of Likert scale responses to 48 statements and an open‐ended critical incident question for students. 2. The Perceptions of Learning Impacts Survey was a similar survey for faculty.

    A powder preparation of the oral probiotic Streptococcus salivarius K12 has been given to 19 young otitis media-prone children following a 3-day course of amoxicillin administered as a preliminary to ventilation tube placement. In two subjects, the use of strain K12 appeared to effect the expansion of an indigenous population of inhibitory S. salivarius. In other children, strain K12 colonisation extended beyond the oral cavity to also include the nasopharynx or adenoid tissue. The relatively low proportion (33%) of subjects that colonised was attributed to failure of the amoxicillin pre-treatment to sufficiently reduce the indigenous S. salivarius populations prior to dosing with strain K12 powder.

  11. "Flipping" educational technology professional development for K-12 educators

    Science.gov (United States)

    Spencer, Daniel

    As the demand for more effective professional development increases in K-12 schools, trainers must adjust their training methods to meet the needs of their teacher learners. Just as lecture-heavy, teacher-centered instruction only meet the learning needs of a small minority of students, "sit and get" professional development rarely results in the teachers gaining the skills and confidence necessary to use technology effectively in their instruction. To resolve the frustrations of teachers related to ineffective professional development, a "Flipped PD" training model was developed based on the learning needs of adult learners, the integration of technological, pedagogical, and content knowledge (TPACK), learning activities, and the Flipped Classroom concept. Under this model, training shifts from a passive, trainer-centered format, to an active, learner-centered format where teachers learn to use technology in their classrooms by first focusing on pedagogical issues, then choosing the options that work best for addressing those issues in their unique situation, and completing "learn-by-doing" projects. Those who participate in "Flipped PD" style trainings tend to have more confidence upon completion that they can use the tools they were trained on in their teaching, as well as believe that the PD was engaging and a good use of their time.

    The lack of diversity in physics is a known problem, and yet efforts to change our demographics have only had minor effects during the last decade. I will explain some of the hidden barriers that dissuade underrepresented minorities in becoming physicists using a framework borrowed from sociology, Maslow's hierarchy of needs. I will draw from current research at the undergraduate to faculty levels over a variety of STEM fields that are also addressing a lack of diversity. I will also provide analysis from the Joint Institute for Nuclear Astrophysics Center for the Evolution of Elements (JINA-CEE) outreach programs to understand the likelihood of current K-12 students in becoming physicists. Specifically, I will present results from the pre-surveys from our Art 2 Science Camps (ages 8-14) about their attitudes towards science as well as results from analysis of teacher recommendations for our high school summer program. I will conclude with a positive outlook describing the pipeline created by JINA-CEE to retain students from middle school through college. This work was supported in part by the National Science Foundation under Grant No. PHY-1430152 (JINA Center for the Evolution of the Elements).

    Chen, R. F.; Lustick, D. S.; Lohmeier, J.; Thompson, S. R.

    2015-12-01

    Cool science is an art contest where K12 students create placards (7" x 22") to educate the public about climate change. Students are prompted to create their artwork in response to questions such as: What is the evidence for climate change? How does climate change impact your local community? What can you do to reduce the impacts of climate change? In each of three years, 500-600 student entrees have been submitted from more than 12 school districts across Massachusetts. A panel of judges including scientists, artists, rapid transit representatives, and educators chooses elementary, middle, and high school winners. Winners (6), runners-up (6), and honorable mentions (12) and their families and teachers are invited to an annual Cool Science Award Ceremony to be recognized and view winning artwork. All winning artwork is posted on the Cool Science website. The winning artwork (2 per grade band) is converted into placards (11" x 28") and posters (2.5' x 12') that are placed on the inside (placards) and outside (posters) of buses. Posters are displayed for one month. So far, Cool Science was implemented in Lowell, MA where over 5000 public viewers see the posters daily on the sides of Lowell Rapid Transit Authority (LRTA) buses, making approximately 1,000,000 impressions per year. Cool Science acts to increase climate literacy in children as well as the public, and as such promotes intergenerational learning. Using art in conjunction with science learning about climate change appears to be effective at engaging not just traditionally high achieving science students, but also those interested in the creative arts. Hearing winners' stories about how they created their artwork and what this contest meant to them supports the idea that Cool Science attracts a wide diversity of students. Parents discuss climate change with their children. Multiple press releases announcing the winners further promotes the awareness of climate change throughout school districts and their

    Murphy, T.; Wegner, K.; Andersen, T. J.

    2016-12-01

    Twenty years ago, the Internet was still in its infancy, citizen science was a relatively unknown term, and the idea of a global citizen science database was unheard of. Then the Global Learning and Observations to Benefit the Environment (GLOBE) Program was proposed and this all changed. GLOBE was one of the first K-12 citizen science programs on a global scale. An initial large scale ramp-up of the program was followed by the establishment of a network of partners in countries and within the U.S. Now in the 21st century, the program has over 50 protocols in atmosphere, biosphere, hydrosphere and pedosphere, almost 140 million measurements in the database, a visualization system, collaborations with NASA satellite mission scientists (GPM, SMAP) and other scientists, as well as research projects by GLOBE students. As technology changed over the past two decades, it was integrated into the program's outreach efforts to existing and new members with the result that the program now has a strong social media presence. In 2016, a new app was launched which opened up GLOBE and data entry to citizen scientists of all ages. The app is aimed at fresh audiences, beyond the traditional GLOBE K-12 community. Groups targeted included: scouting organizations, museums, 4H, science learning centers, retirement communities, etc. to broaden participation in the program and increase the number of data available to students and scientists. Through the 20 years of GLOBE, lessons have been learned about changing the management of this type of large-scale program, the use of technology to enhance and improve the experience for members, and increasing community involvement in the program.

    that understanding how to properly cite sources was a major area of concern. Students were also confused about whom to ask for help during the research process. Instructional intervention was developed and applied. The survey was re-administered with the addition of items that were based on the interventions. Responses showed a marked improvement in understanding by at least 20%. Some responses improved by as much as 60%. Conclusion - The study validated the Action Research Training Model as the first dimension and conceptual framework that informs and guides instructional practices of school library media specialists and teachers in a K-12 school district. After using the model to examine student-teacher knowledge and understanding of ethical use of information (second dimension, there was recognition of the need to clarify the school’s position on the ethical use of information for teachers and students and provide intentional instruction and interventions for students beginning at an earlier grade level. After being made aware of the results, teachers were anxious to work with library media specialists to address issues and to look for opportunities within research units to collaborate.

  15. Extended Safety Data for the Oral Cavity Probiotic Streptococcus salivarius K12.

    Science.gov (United States)

    Burton, J P; Chilcott, C N; Wescombe, P A; Tagg, J R

    2010-10-01

    Previous studies of the bacteriocin-producing Streptococcus salivarius K12 monitored a variety of intrinsic strain characteristics of potential relevance to its application as an oral probiotic in humans. These included the content of antibiotic resistance and virulence determinants, the production of deleterious metabolic by-products and its genetic stability. In the present study, we examined additional safety factors including the responses of rats to either short- or long-term oral dosing with strain K12 preparations. In addition, the potential genotoxicity of strain K12 was tested using a bacterial reverse mutation assay. To determine the occurrence and concentrations in human saliva of S. salivarius having the same bacteriocin phenotype as strain K12, saliva samples from 780 children were evaluated. The level of dosing with strain K12 required to achieve oral cavity colonization levels similar to those occurring naturally for this type of bacteriocin-producing S. salivarius was established using 100 human subjects. Following the oral instillation of lyophilized S. salivarius K12 cells in these subjects, its persistence was not at levels higher than those found naturally for this type of bacterium. The various sets of data obtained in this study showed no evidence of genotoxicity and no acute or subacute toxicity effects associated with strain K12. Based on the previously published data, the long history of use by humans and the information presented here, it is concluded that S. salivarius K12 is safe for human consumption.

  20. Cataclysms and Catastrophes: A Case Study of Improving K-12 Science Education Through a University Partnership

    Science.gov (United States)

    Fennell, T.; Ellins, K. K.; Morris, M.; Christeson, G.

    2003-12-01

    The K-12 science teacher is always seeking ways of improving and updating their curriculum by integrating the latest research into their most effective classroom activities. However, the daily demands of delivering instruction to large numbers of students coupled with the rapid advances in some fields of science can often overwhelm this effort. The NSF-sponsored Cataclysms and Catastrophes curriculum, developed by scientists from the The University of Texas at Austin Institute for Geophysics (UTIG) and Bureau of Economic Geology (BEG), middle and high school teachers, and UT graduate students (NSF GK-12 fellows) working together through the GK-12 program, is a textbook example of how universities can facilitate this quest, benefiting education at both K-12 and university levels. In 1992, "The Great K-T Extinction Debate" was developed as an activity in the Planet Earth class at the Liberal Arts and Science Academy of Austin as an interdisciplinary approach to science. Taking advantage of the media attention generated by the impact scenario for the K-T extinction, the activity consists of students participating in a simulated senate hearing on the potential causes of the K-T extinction and their implications for society today. This activity not only exposes students to the wide range of science involved in understanding mass extinctions, but also to the social, political and economic implications when this science is brought into the public arena and the corresponding use of data in decision making and disaster preparedness. While "The Great K-T Extinction Debate" was always a popular and effective activity with students, it was in desperate need of updating to keep pace with the evolving scientific debate over the cause of the K-T extinction and the growing body of impact evidence discovered over the past decade. By adding two inquiry-based learning activities that use real geophysical data collected by scientists studying the buried Chicxulub feature as a

    This Technical Support Document (TSD) describes the process and methodology for the development of the Advanced Energy Design Guide for K-12 School Buildings: Achieving 50% Energy Savings Toward a Net Zero Energy Building (AEDG-K12) (ASHRAE et al. 2011a). The AEDG-K12 provides recommendations for achieving 50% whole-building energy savings in K-12 schools over levels achieved by following ANSI/ASHRAE/IESNA Standard 90.1-2004, Energy Standard for Buildings Except Low-Rise Residential Buildings (Standard 90.1-2004) (ASHRAE 2004b). The AEDG-K12 was developed in collaboration with the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), the American Institute of Architects (AIA), the Illuminating Engineering Society of North America (IES), the U.S. Green Building Council (USGBC), and the U.S. Department of Energy (DOE).

    To investigate the antimicrobial activity of the bacteriocin-producing strain Streptococcus salivarius K12 against several bacteria involved in halitosis. The inhibitory activity of S. salivarius K12 against Solobacterium moorei CCUG39336, four clinical S. moorei isolates, Atopobium parvulum ATCC33793 and Eubacterium sulci ATCC35585 was examined by a deferred antagonism test. Eubacterium saburreum ATCC33271 and Parvimonas micra ATCC33270, which have been tested in previous studies, served as positive controls, and the Gram-negative strain Bacteroides fragilis ZIB2800 served as a negative control. Additionally, the occurrence of resistance in S. moorei CCUG39336 to S. salivarius K12 was analysed by either direct plating or by passage of S. moorei CCUG39336 on chloroform-inactived S. salivarius K12-containing agar plates. S. salivarius K12 suppressed the growth of all Gram-positive bacteria tested, but the extent to which the bacteria were inhibited varied. E. sulci ATCC35585 was the most sensitive strain, while all five S. moorei isolates were inhibited to a lesser extent. Natural resistance seems to be very low in S. moorei CCUG39336, and there was only a slight decrease in sensitivity after exposure to S. salivarius K12 over 10 passages. Our studies demonstrate that S. salivarius K12 has antimicrobial activity against bacteria involved in halitosis. This strain might be an interesting and valuable candidate for the development of an antimicrobial therapy for halitosis. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Recurrent pharyngo-tonsillar infections caused by group A beta-hemolytic streptococci (GABHS) occur frequently in young children, and the treatment of these infections contributes substantially to the total current requirement for antibiotic prescribing. Our study goal was to assess through a retrospective observational analysis whether the administration of the oral probiotic, Streptococcus salivarius K12 (SsK12), could reduce the occurrence of GABHS pharyngo-tonsillar infections in children who had a recent history of recurrent episodes of these infections. Twelve primary care pediatricians identified, through their databases, a total of 130 children who had experienced recurrent GABHS pharyngo-tonsillar infections over a period of at least 6-12 months prior to their inclusion in the study. Of these children, 76 then undertook a 90-day program requiring once-a-day dosing with a commercially available (Bactoblis) lozenge containing SsK12. No probiotic supplement was given to the remaining 54 (control) children. Each subject was monitored for the occurrence of GABHS pharyngo-tonsillitis and also for acute otitis media, bronchitis, sinusitis, and bronchopneumonia for at least 12 months following their entry to the study. Even 9 months after the use of SsK12 had been stopped, the probability of new GABHS infections was significantly lower (P>0.001) when compared to the period before dosing commenced. When compared to the untreated children, those taking SsK12 appear to have had significantly fewer GABHS infections both during the 90-day period of prophylaxis and during the following 9 months (P<0.001). These observations are supportive of the use of probiotic SsK12 for the control of recurrent GABHS pharyngo-tonsillar infections in children, and as an associated benefit, the use of this probiotic could lead to reduced antibiotic consumption. Follow-up controlled prospective studies should now be initiated in order to further establish the efficacy of this newly

    To maximize the contributions of nanotechnology to this society, at least 60 countries have put efforts into this field. In Taiwan, a government-funded K-12 Nanotechnology Programme was established to train K-12 teachers with adequate nanotechnology literacy to foster the next generation of Taiwanese people with sufficient knowledge in nanotechnology. In the present study, the Nanotechnology Attitude Scale for K-12 teachers (NAS-T) was developed to assess K-12 teachers' attitudes toward nanotechnology. The NAS-T included 23 Likert-scale items that can be grouped into three components: importance of nanotechnology, affective tendencies in science teaching, and behavioural tendencies to teach nanotechnology. A sample of 233 K-12 teachers who have participated in the K-12 Nanotechnology Programme was included in the present study to investigate the psychometric properties of the NAS-T. The exploratory factor analysis of this teacher sample suggested that the NAS-T was a three-factor model that explained 64.11% of the total variances. This model was also confirmed by the confirmatory factor analysis to validate the factor structure of the NAS-T. The Cronbach's alpha values of three NAS-T subscales ranged from 0.89 to 0.95. Moderate to strong correlations among teachers' NAS-T domain scores, self-perception of own nanoscience knowledge, and their science-teaching efficacy demonstrated good convergent validity of the NAS-T. As a whole, psychometric properties of the NAS-T indicated that this instrument is an effective instrument for assessing K-12 teachers' attitudes toward nanotechnology. The NAS-T will serve as a valuable tool to evaluate teachers' attitude changes after participating in the K-12 Nanotechnology Programme.

    To determine whether dosing with bacteriocin-producing Streptococcus salivarius following an antimicrobial mouthwash effects a change in oral malodour parameters and in the composition of the oral microbiota of subjects with halitosis. Twenty-three subjects with halitosis undertook a 3-day regimen of chlorhexidine (CHX) mouth rinsing, followed at intervals by the use of lozenges containing either S. salivarius K12 or placebo. Assessment of the subjects' volatile sulphur compound (VSC) levels 1 week after treatment initiation showed that 85% of the K12-treated group and 30% of the placebo group had substantial (>100 ppb) reductions. The bacterial composition of the saliva was monitored by culture and PCR-denaturing gradient gel electrophoresis (PCR-DGGE). Changes in the PCR-DGGE profiles occurred in most subjects following K12 treatment. In vitro testing showed that S. salivarius K12 suppressed the growth of black-pigmented bacteria in saliva samples and also in various reference strains of bacteria implicated in halitosis. Administration of bacteriocin-producing S. salivarius after an oral antimicrobial mouthwash reduces oral VSC levels. The outcome of this preliminary study indicates that the replacement of bacteria implicated in halitosis by colonization with competitive bacteria such as S. salivarius K12 may provide an effective strategy to reduce the severity of halitosis.

    Full Text Available Microbes, as one of the primary producers of the biosphere, play an important role in ecosystems. Exploring the mechanism of adaptation and resistance of microbial population to various environmental factors has come into focus in the fields of modern microbial ecology and molecular ecology. However, facing the increasingly serious problem of acoustic pollution, very few efforts have been put forth into studying the relation of single cell organisms and sound field exposure. Herein, we studied the biological effects of sound exposure on the growth of E. coli K-12 with different acoustic parameters. The effects of sound exposure on the intracellular macromolecular synthesis and cellular morphology of E. coli K-12 were also analyzed and discussed. Experimental results indicated that E. coli K-12 exposed to sound waves owned a higher biomass and a faster specific growth rate compared to the control group. Also, the average length of E. coli K-12 cells increased more than 27.26%. The maximum biomass and maximum specific growth rate of the stimulation group by 8000 Hz, 80dB sound wave was about 1.7 times and 2.5 times that of the control group, respectively. Moreover, it was observed that E. coli K-12 can respond rapidly to sound stress at both the transcriptional and posttranscriptional levels by promoting the synthesis of intracellular RNA and total protein. Some potential mechanisms may be involved in the responses of bacterial cells to sound stress.

  3. K-12 Teacher Understanding of Energy Conservation: Conceptual Metaphor, Dissipation, and Degradation

    Science.gov (United States)

    Daane, Abigail R.

    In K-12 educational settings, conservation of energy is typically presented in two ways: the conservation of energy principle (energy is neither created nor destroyed) and the sociopolitical need to conserve energy (we guard against energy being used up). These two meanings of conservation typically remain disconnected from each other and can appear contradictory, even after instruction. In an effort to support teachers in building robust understandings of energy from their existing knowledge, I designed a study to investigate the productive ideas in K-12 teachers' conversations about energy. A micro-analysis of discourse, gestures, and artifacts of professional development courses revealed teachers' productive ideas about three aspects of energy: conceptual metaphor, dissipation and degradation. In learning about energy, K-12 teachers come to use conceptual metaphors in their own language and value attending to students' metaphorical language as a means of formative assessment. Teachers' conversations about dissipation suggest that apparent difficulties with energy conservation may have their roots in a strong association between forms of energy (thermal) and their perceptible indicators (warmth). Teachers address this challenge by employing an exaggeration strategy to locate the dissipated thermal energy, making the energy indicator perceptible. Finally, teachers' unprompted statements about sociopolitical aspects of energy are related to both statements from the NGSS and aspects of energy degradation. I conclude that energy conservation can be better taught and learned in K-12 Education by: 1) understanding and applying conceptual metaphors about energy in K-12 settings, 2) using prior experiences to better understand dissipative energy processes involving imperceptible thermal energy, thereby understanding how energy conservation applies in all situations, and 3) connecting productive ideas about sociopolitical aspects of energy to canonical physics.

    Can professional engineers, mathematicians, and scientists have a positive impact on K-12 math and science education? The experience of the Santa Fe Alliance for Science, and several other like-minded organizations, indicates that they can indeed. But success is by no means assured. Good scientists are not automatically good educators, but they can learn enough about pedagogy, classroom, and community to do well. This discussion will be oriented around three major points: lessons learned, prospects for the future, and how our effort fits into state-wide plans for re-inventing K-12 math and science education in New Mexico.

    2013-09-01

    In the present work, the frequency-dependent effects of extremely low-frequency electromagnetic field (ELF EMF) on Escherichia coli K-12 growth have been studied. The frequency-dependent effects of ELF EMF have shown that it can either stimulate or inhibit the growth of microbes. However, the mechanism by which the ELF EMF affects the bacterial cells is not clear yet. It was suggested that the aqua medium can serve as a target through which the biological effect of ELF EMF on microbes may be realized. To check this hypothesis, the frequency-dependent effects (2, 4, 6, 8, 10 Hz, B = 0.4 mT, 30 min) of ELF EMF on the bacterial growth were studied in both cases where the microbes were in the culture media during the exposure and where culture media was preliminarily exposed to the ELF EMF before the addition of bacteria. For investigating the cell proliferation, the radioactive [(3)H]-thymidine assay was carried out. It has been shown that EMF at 4 Hz exposure has pronounced stimulation while at 8 Hz it has inhibited cell proliferation.

NNIN's education and outreach programs are large and varied and includes outreach to the K-12 community in the form of professional development workshops and school programs. Two important components of nanoscale science education are understanding size and scale and the tools used in nanoscale science and engineering (NSE). As part of our K-12 endeavors, we educate K-12 students and teachers about the tools of nanoscience by providing experiences with the Hitachi TM 3000 tabletop Scanning Electron Microscope (SEM). There are three of these across the network that are used in education and outreach. This paper will discuss approaches we use to engage the K-12 community at NNIN's site at Georgia Institute of Technology to understand size and scale and the applications of a variety of microscopes to demonstrate the imaging capabilities of these to see both the micro and nano scales. We not only use the tabletop SEM but also include USB digital microscopes, a Keyence VHX- 600 Digital Microscope, and even a small lens used with smart phones. The goal of this outreach is to educate students as well as teachers about the capabilities of the various instruments and their importance at different size scales.

    2004-12-01

    The Science, Technology, Engineering, and Mathematics Teacher Preparation (STEMTP) program at the University of Colorado has been designed to recruit and train prospective K-12 science teachers while improving student learning through interactive teaching. The program has four key goals: (1) recruit undergraduate students into K-12 science education, (2) provide these prospective teachers with hands-on experience in an interactive teaching pedagogy, (3) create an intergrated program designed to support (educationally, socially, and financially) and engage these prospective science teachers up until they obtain liscensure and/or their masters degree in education, and (4) improve student learning in large introductory science classes. Currently there are 31 students involved in the program and a total of 72 students have been involved in the year and a half it has been in existence. I will discuss the design of the STEMTP program, the success in recruiting K-12 science teachers, and the affect on student learning in a large lecture class of implementing interactive learning pedagogies by involving these prospective K-12 science teachers. J. L. Rosenberg would like to acknowledge the NSF Astronomy and Astrophysics Fellowship for support for this work.

  12. Females and STEM: Determining the K-12 Experiences that Influenced Women to Pursue STEM Fields

    Science.gov (United States)

    Petersen, Anne Marie

    In the United States, careers in the fields of Science, Technology, Engineering, and Mathematics (STEM) are increasing yet there are not enough trained personnel to meet this demand. In addition, of those that seek to pursue STEM fields in the United States, only 26% are female. In order to increase the number of women seeking STEM based bachelor's degrees, K-12 education must provide a foundation that prepares students for entry into these fields. The purpose of this phenomenological study was to determine the perceived K-12 experiences that influenced females to pursue a STEM field. Twelve college juniors or seniors seeking a degree in Biology, Mathematics, or Physics were interviewed concerning their K-12 experiences. These interviews were analyzed and six themes emerged. Teacher passion and classroom characteristics such as incorporating challenging activities played a significant role in the females' decisions to enter STEM fields. Extra-curricular activities such as volunteer and mentor opportunities and the females' need to benefit others also influenced females in their career choice. Both the formal (within the school) and informal (outside of the traditional classroom) pipeline opportunities that these students encountered helped develop a sense of self-efficacy in science and mathematics; this self-efficacy enabled them to persist in pursuing these career fields. Several participants cited barriers that they encountered in K-12 education, but these barriers were primarily internal as they struggled with overcoming self-imposed obstacles in learning and being competitive in the mathematics and science classrooms. The experiences from these female students can be used by K-12 educators to prepare and encourage current female students to enter STEM occupations.

    The Initiating New Science Partnerships in Rural Education (INSPIRE) program at Mississippi State University (MSU), funded by the NSF Graduate STEM Fellows in K-12 Education (GK12) program, focuses on the advancement of Earth and Space science education in K-12 classrooms. INSPIRE is currently in its second year of partnering ten graduate students from the STEM fields of Geosciences, Engineering and Chemistry at MSU with five teachers from local, rural school districts. The five year project serves to increase inquiry and technology experiences in science and math while enhancing graduate student's communication skills as they create interactive lessons linking their STEM research focus to the state and national standards covered in the classrooms. Each graduate student is responsible for the development of two lessons each month of the school year that are then published on the INSPIRE project webpage, www.gk12.msstate.edu, where they are a free resource for any K-12 classroom teacher seeking innovative activities for their classrooms. Many of the participating teachers and graduate students share activities developed with non-participating teachers, expanding INSPIRE's outreach throughout the local community. Numerous challenges were met during the formation of the program as well as throughout the first year in which the project management team worked together to find solutions ensuring that INSPIRE maintained successful partnerships for all involved. Proposed solutions of the following key components were identified by INSPIRE through the development, implementation, and continuous evaluation (internal and external) of the first year of the program as areas that can pose challenges to the construction of strong relationships between STEM research and K-12 classrooms: initializing the partnerships with the K-12 classrooms and STEM graduate fields at the university; maintaining strong partnerships; providing appropriate training and support; developing sound

  1. Global TIE: Developing a Virtual Network of Robotic Observatories for K-12 Education

    Science.gov (United States)

    Mayo, L. A.; Clark, G.

    2001-11-01

    Astronomy in grades K-12 is traditionally taught (if at all) using textbooks and a few simple hands-on activities. In addition, most students, by High School graduation, will never have even looked through the eyepiece of a telescope. The possibility now exists to establish a network of research grade telescopes, no longer useful to the professional astronomical community, that can be made accessible to schools all across the country through existing IT technologies and applications. These telescopes could provide unparalleled research and educational opportunities for a broad spectrum of K-12 and college students and turns underutilized observatory facilities into valuable, state-of-the-art teaching centers. The NASA-sponsored Telescopes In Education (TIE, http://tie.jpl.nasa.gov) project has been wildly successful in engaging the K-12 education community in real-time, hands-on, interactive astronomy activities. Hundreds of schools in the US, Australia, Canada, England, and Japan have participated in the TIE program, remotely controlling the 24-inch telescope at the Mount Wilson Observatory from their classrooms. In recent years, several (approximately 20 to date) other telescopes have been, or are in the process of being, outfitted for remote use as TIE affiliates. Global TIE integrates these telescopes seamlessly into one virtual observatory and provides the services required to operate this facility, including a scheduling service, tools for data manipulation, an online proposal review environment, an online "Virtual TIE Student Ap J" for publication of results, and access to related educational materials provided by the TIE community.

    1981-01-01

    The tryptophanase structural gene, tnaA, of Escherichia coli K-12 was cloned and sequenced. The size, amino acid composition, and sequence of the protein predicted from the nucleotide sequence agree with protein structure data previously acquired by others for the tryptophanase of E. coli B. Physiological data indicated that the region controlling expression of tnaA was present in the cloned segment. Sequence data suggested that a second structural gene of unknown function was located distal ...

    The K-12 student population is becoming increasingly diverse in the United States. In particular, the number of English Language Learners (ELLs) rose from 4.7 million in 1980 to 11.2 million in 2009, more than doubling from 10% to 21% of the student population (U.S. Department of Education n.d.). At approximately 1.8 million, the state of…

  5. Structural genes for thiamine biosynthetic enzymes (thiCEFGH) in Escherichia coli K-12.

    OpenAIRE

    Vander Horn, P B; Backstrom, A D; Stewart, V; Begley, T. P.

    1993-01-01

    Escherichia coli K-12 synthesizes thiamine pyrophosphate (vitamin B1) de novo. Two precursors [4-methyl-5-(beta-hydroxyethyl)thiazole monophosphate and 4-amino-5-hydroxymethyl-2-methylpyrimidine pyrophosphate] are coupled to form thiamine monophosphate, which is then phosphorylated to make thiamine pyrophosphate. Previous studies have identified two classes of thi mutations, clustered at 90 min on the genetic map, which result in requirements for the thiazole or the hydroxymethylpryimidine. W...

  6. Partnerships---A Way of Making Astrophysics Research Accessible to the K--12 Community through the Internet and World Wide Web

    Hawkins, I.; Battle, R.; Miller-Bagwell, A.

    1996-05-01

    We describe a partnership approach in use at UC Berkeley's Center for EUV Astrophysics (CEA) that facilitates the adaptation of astrophysics data and information---in particular from NASA's EUVE satellite---for use in the K--12 classroom. Our model is founded on a broad collaboration of personnel from research institutions, centers of informal science teaching, schools of education, and K--12 schools. Several CEA-led projects follow this model of collaboration and have yielded multimedia, Internet-based, lesson plans for grades 6 through 12 that are created and distributed on the World Wide Web (http://www.cea.berkeley.edu/Education). Use of technology in the classroom can foster an environment that more closely reflects the processes scientists use in doing research (Linn, diSessa, Pea, & Songer 1994, J.Sci.Ed.Tech., ``Can Research on Science Learning and Instruction Inform Standards for Science Education?"). For instance, scientists rely on technological tools to model, analyze, and ultimately store data. Linn et al. suggest introducing technological tools to students from the earliest years to facilitate scientific modeling, scientific collaborations, and electronic communications in the classroom. Our investigation aims to construct and evaluate a methodology for effective participation of scientists in K--12 education, thus facilitating fruitful interactions with teachers and other educators and increasing effective use of technology in the classroom. We describe several team-based strategies emerging from these project collaborations. These strategies are particular to the use of the Internet and World Wide Web as relatively new media for authoring K--12 curriculum materials. This research has been funded by NASA contract NAS5-29298, NASA grant ED-90033.01-94A to SSL/UCB, and NASA grants NAG5-2875 and NAGW-4174 to CEA/UCB.

  7. Biochemical genetics of the cryptic gene system for cellobiose utilization in Escherichia coli K12.

    Science.gov (United States)

    Kricker, M; Hall, B G

    1987-03-01

    The cellobiose catabolic system of Escherichia coli K12 is being used to study the role of cryptic genes in microbial evolution. Wild-type E. coli K12 do not utilize the beta-glucoside sugars, arbutin, salicin and cellobiose. A Cel+ (cellobiose utilizing) mutant which grows on cellobiose, arbutin, and salicin was isolated previously from wild-type E. coli K12. Biochemical assays indicate that a cel structural gene (celT) specifies a single transport protein that is a beta-glucoside specific enzyme of the phosphoenolpyruvate-dependent phosphotransferase system. The transport protein phosphorylates beta-glucosides at the expense of phosphoenolpyruvate. A single phosphoglucosidase, specified by celH, hydrolyzes phosphorylated cellobiose, arbutin, and salicin. The genes of the cel system are expressed constitutively in the Cel+ mutant, whereas they are not expressed at a detectable level in the wild-type strain. The transport and hydrolase genes are simultaneously silenced or simultaneously expressed and thus constitute an operon. Cel+ strains which fail to utilize one or more beta-glucosides express the transport system at a lower level than do Cel+ strains which grow on all three beta-glucosides. Other strains inducibly express a gene which specifies transport of arbutin but not the other beta-glucosides. The arbutin transport gene, arbT, maps outside of the cel locus.

  8. Advanced Energy Retrofit Guide: Practical Ways to Improve Energy Performance, K-12 Schools (Book)

    Energy Technology Data Exchange (ETDEWEB)

    2013-12-01

    The U.S. Department of Energy developed the Advanced Energy Retrofit Guides (AERGs) to provide specific methodologies, information, and guidance to help energy managers and other stakeholders plan and execute energy efficiency improvements. Detailed technical discussion is fairly limited. Instead, we emphasize actionable information, practical methodologies, diverse case studies, and unbiased evaluations of the most promising retrofit energy efficiency measures for each building type. A series of AERGs is under development, addressing key segments of the commercial building stock. K-12 schools were selected as one of the highest priority building sectors, because schools affect the lives of most Americans. They also represent approximately 8% of the energy use and 10% of the floor area in commercial buildings nationwide. U.S. K-12 school districts spend more than $8 billion each year on energy - more than they spend on computers and textbooks combined. Most occupy older buildings that often have poor operational performance - more than 30% of schools were built before 1960. The average age of a school is about 42 years - which is nearly the expected serviceable lifespan of the building. K-12 schools offer unique opportunities for deep, cost-effective energy efficiency improvements, and this guide provides convenient and practical guidance for exploiting these opportunities in the context of public, private, and parochial schools.

  9. CESAME: Providing High Quality Professional Development in Science and Mathematics for K-12 Teachers

    2002-04-01

    It is appropriate that after almost half a century of Science and Mathematics education reform we take a look back and a peek forward to understand the present state of this wonderfully complex system. Each of the components of this system including teaching, professional development, assessment, content and the district K-12 curriculum all need to work together if we hope to provide quality science, mathematics and technology education for ALL students. How do the state and national standards drive the system? How do state policies on student testing and teacher licensure come into play? How do we improve the preparation, retention and job satisfaction of our K-12 teachers? What initiatives have made or are making a difference? What else needs to be done? What can the physics community do to support local efforts? This job is too big for any single organization or individual but we each can contribute to the effort. Our Center at Northeastern University, with support from the National Science Foundation, has a sharply defined focus: to get high quality, research-based instructional materials into the hands of K-12 classroom teachers and provide the support they need to use the materials effectively in their classrooms.

  10. Environmental and genetic factors affecting mutability to aminoglycoside antibiotics among Escherichia coli K12 strains

    Directory of Open Access Journals (Sweden)

    Monteiro A.C.M.

    2003-01-01

    Full Text Available Environmental and genetic factors affecting the in vitro spontaneous mutation frequencies to aminoglycoside resistance in Escherichia coli K12 were investigated. Spontaneous mutation frequencies to kanamycin resistance were at least 100 fold higher on modified Luria agar (L2 plates, when compared to results obtained in experiments carried out with Nutrient agar (NA plates. In contrast to rifampincin, the increased mutability to kanamycin resistance could not be attributed to a mutator phenotype expressed by DNA repair defective strains. Kanamycin mutant selection windows and mutant preventive concentrations on L2 plates were at least fourfold higher than on NA plates, further demonstrating the role of growth medium composition on the mutability to aminoglycosides. Mutability to kanamycin resistance was increased following addition of sorbitol, suggesting that osmolarity is involved on the spontaneous mutability of E. coli K12 strains to aminoglycosides. The spontaneous mutation rates to kanamycin resistance on both L2 and NA plates were strictly associated with the selective antibiotic concentrations. Moreover, mutants selected at different antibiotic concentrations expressed heterogeneous resistance levels to kanamycin and most of them expressing multiple resistance to all tested aminoglycoside antibiotics (gentamicin, neomycin, amykacin and tobramycin. These results will contribute to a better understanding of the complex nature of aminoglycoside resistance and the emergence of spontaneous resistant mutants among E. coli K12 strains.

    This paper describes a study carried out with K-12 students. This study is focused on understanding the motivation of these students on the use of robots in the Project Area curricular unit and to understand whether they want to continue their studies in technology areas. K-12 students participated in the RoboParty® event, where the main task is to assemble and program a robot. In other words, the students, in a simple and entertaining way and guided by qualified tutors, learned how to build a robot. At the end of the academic year, a questionnaire was applied to identify and evaluate the K-12 students' opinions regarding the experience. The students’ reaction to this experience as well to the direct contact with the university environment was quite positive.

    2012-01-01

    This paper highlights the diverse possibilities in the rich community of educators from the Conceptual Learning of Science (CoLoS) and Open Source Physics (OSP) movement to engage, enable and empower educators and students, to create interactive digital media through computer modeling. This concept revolves around a paradigmatic shift towards participatory learning through immersive computer modeling, as opposed to using technology for information transmission. We aim to engage high school educators to professionally develop themselves by creating and customizing simulations possible through Easy Java Simulation (Ejs) and its learning community. Ejs allows educators to be designers of learning environments through modifying source codes of the simulation. Educators can conduct lessons with students' using these interactive digital simulations and rapidly enhance the simulation through changing the source codes personally.

  10. Sense and Sensibility: The Case for the Nationwide Inclusion of Engineering in the K-12 Curriculum

    Science.gov (United States)

    Lindberg, Robert E.; Pinelli, Thomas E.; Batterson, James G.

    2008-01-01

    The competitive status of the United States is inextricably linked to innovation just as innovation is inseparable from science, technology, engineering, and mathematics. To stay competitive in innovation requires that the United States produce a 21st century workforce complete with requisite education, training, skills, and motivation. If we accept a priori that science, technology, engineering, and mathematics education are crucial to competitiveness and innovation and that, in terms of innovation, mathematics, science, and engineering are interdependent, why are mathematics and science uniformly ubiquitous in the K-12 curriculum while engineering is conspicuously absent? We are passionate in our belief that the uniform addition of engineering to the K-12 curriculum will help ensure that the nation has "the right" 21st Century workforce. Furthermore, we believe that a nationwide effort, led by a coalition of engineering academics, practitioners, and societies is required to turn this goal into reality. However, accomplishing this goal necessitates, as we are reminded by the title of Jane Austen's timeless novel, "Sense and Sensibility", a workable solution that seeks the "middle ground" between passion and reason. We begin our paper by making two essential points: Engineers are not scientists. Engineering exists separate from science, has its own specialized knowledge community apart from science, and it is largely responsible for many of the most significant advancements and improvements in the quality of our life. Our workable solution requires that K-12 education, nationwide, accommodate the inclusion of engineering as a stand alone curriculum and we offer three reasons to support our position: (1) workforce development, (2) stimulating interest in STEM (science, technology, engineering, and mathematics) courses and careers, and (3) creating a technologically literate society. We conclude with some thoughts on how this important goal can be accomplished.

    2014-01-01

    The University of New England's Center for Excellence in the Neurosciences has developed a successful and growing K-12 outreach program that incorporates undergraduate and graduate/professional students. The program has several goals, including raising awareness about fundamental issues in neuroscience, supplementing science education in area schools and enhancing undergraduate and graduate/professional students' academic knowledge and skill set. The outreach curriculum is centered on core neuroscience themes including: Brain Safety, Neuroanatomy, Drugs of Abuse and Addiction, Neurological and Psychiatric Disorders, and Cognition and Brain Function. For each theme, lesson plans were developed based upon interactive, small-group activities. Additionally, we've organized our themes in a "Grow-up, Grow-out" approach. Grow-up refers to returning to a common theme, increasing in complexity as we revisit students from early elementary through high school. Grow-out refers to integrating other scientific fields into our lessons, such as the chemistry of addiction, the physics of brain injury and neuronal imaging. One of the more successful components of our program is our innovative team-based model of curriculum design. By creating a team of undergraduate, graduate/professional students and faculty, we create a unique multi-level mentoring opportunity that appears to be successful in enhancing undergraduate students' skills and knowledge. Preliminary assessments suggest that undergraduates believe they are enhancing their content knowledge and professional skills through our program. Additionally, we're having a significant, short-term impact on K-12 interest in science. Overall, our program appears to be enhancing the academic experience of our undergraduates and exciting K-12 students about the brain and science in general.

    Scientists are very interested in the formation of contrails, both the type and the coverage. To be detected by a satellite-born instrument, the contrail must be of a certain size, which means that some contrails go undetected. The K-12 education community is assisting with the study of contrails by participating in a network of student observers. To provide a venue for student contrail observations, the GLOBE Contrails protocol was developed as part of the GLOBE Atmospheric Science protocols. The first year of observations has provided a rich resource for researcher.

    2004-01-01

    A reconnaissance study of the geology professional development program known as RockCamp was initiated to examine the sustained, or recurrent, participation of K-12 science teachers. Open-ended interviews, concept mapping, and creative writing assignments were used to explore the perceptions of six teachers possessing an exceptional record of participation. Efficacy, fun, right time of life, and support emerged as unanimous reasons for recurrent participation. Content, friendship, and methodology were very important. College credit was not critical. These teachers' perceptions suggest their sustained involvement in the RockCamp Program is stimulated by situated learning experiences stressing a compare, contrast, connect, and construct pedagogy within a supportive learning community.

    Over the past 50 years, identity has provided us with a dynamic tool to understand and examine how people are constituted as agents as well as subjects of culturally constructed, socially enacted worlds. Pertinent to this conceptualization, Skerrett and Sevian focus on science and mathematics faculty's identities and seek to understand how certain aspects of their identities mediate certain motivations to involvement in K-12 service. While I believe that the authors presented an affluent discussion of agency from the perspective of identity, I think that if we are to understand agency from a sociocultural perspective, we have to magnify a view of identity and agency in the figured world of practice/activity. My main goal is not only to reclaim the importance of the individual dimension and agency within a profoundly social view of the self, but also to highlight the figured contextual factors that would either enable or constrain STEM faculty's involvement in K-12 outreach. After first outlining the perspective of identity and agency that was adopted by Skerrett and Sevian, I extend the discussion of Skerrett and Sevian to move forward toward a figured world of partnership. I conclude by positing that the third generation of activity theory has a potential for contributing to our understanding of how the social institutional context and its structure is important to our understanding of individual agency.

    This study evaluated the efficacy of a supercritical carbon dioxide (SCCO(2)) system with a gas-liquid porous metal contactor for eliminating Escherichia coli K12 in apple cider. Pasteurized, preservative-free apple cider was inoculated with E. coli K12 and processed using the SCCO(2) system at CO(2) concentrations of 0-10% (wt.%, g CO(2)/100g product), outlet temperatures of 34, 38, and 42 degrees C, a system pressure of 7.6 MPa, and a flow rate of 1L/min. Increased CO(2) concentrations and temperatures significantly (Pcider. SEM observations showed morphological changes in the cell envelope after SCCO(2) processing. At a processing condition of 8% and 38 degrees C, the reduction of E. coli was 6.03 log and the sublethal injury of the survivors was 84%. The regrowth or survival of E. coli in SCCO(2) processed apple cider was not observed during storage for 28 days at 4, 8, and 20 degrees C. Thus this study showed the potential of SCCO(2) processing with a gas-liquid porous metal contactor for the nonthermal pasteurization of apple cider. Copyright 2009. Published by Elsevier B.V.

    The newly-released Next Generation Science Standards (NGSS) have been under development for a few years with broad community input and explicit involvement of many states likely to adopt these as their own science standards. Several key features of the NGSS make these a substantial advance from the existing National Science Education Standards (NRC 1996), including focus on three dimensions previously outlined in A Framework for K-12 Science Education (NRC 2011): Science and Engineering Practices; Cross-cutting Concepts; and Disciplinary Core Ideas. What are the implications of all this now for K-12 educators, in the immediate term and in the long-term? What do the NGSS imply for EPO professionals, especially those involved in science curriculum development and teacher professional development? What should higher education faculty know about the NGSS, especially as it relates to the preparation of incoming college students, as well as the education of future elementary and secondary science teachers in college (including in Astro 101-type courses)?

  3. A qualitative assessment of preservice elementary teachers' formative perceptions regarding engineering and K-12 engineering education

    Culver, Dennis Eugene

    Current teacher education programs provide limited instruction for preservice elementary teachers regarding the incorporation or teaching of engineering concepts and skills in their classrooms. Few studies have been conducted that focus specifically on preservice elementary teachers' formative perceptions and receptivity towards engineering education. That is, not enough is known about what preservice teachers know and think about engineering. The purpose of this qualitative research study was to investigate how forty-four preservice elementary teachers' from a large Midwestern university approached engineering design, the perceptions of engineering and K-12 engineering education that they possessed, and their level of receptiveness with regards to K-12 engineering education. Data were collected using a demographic survey, journal entries, observations, and focus group discussions. The written, verbal, and visual data collected in this study were analyzed using conventional qualitative content analysis, which consisted of inductively developing categories and codes after repeatedly examining the data. The results of the study indicate that the preservice elementary teachers did not utilize any deliberate design process when engaged in a design task. Engineering was perceived as being synonymous with construction and that engineering design consists of trial and error. Participants envisioned their students succeeding in engineering due to their students' prior knowledge, not necessarily the actions of themselves as the teacher. With regards to receptivity, participants expressed apprehension and optimism along with fear and pessimism. Tangential factors also impacted the receptivity of participants.

    Simple water quality test kits were used in a series of K-12 classrooms to demonstrate scientific processes and to motivate learning in K-12 students. While focused on student learning, this project also allowed collection of regional data on groundwater quality (primarily nitrate) in the study area. The project consisted of development and administration of a weeklong groundwater quality unit introduced to K-12 schools in northern Indiana and taught by a graduate student in an engineering discipline. The structure of the week started with an introduction to basic groundwater concepts modified for the specific grade level; for this project the students ranged from grades 4-12. In addition to groundwater basics, the purpose of the collection of the water quality data, as well as relevance to the research of the graduate student, were outlined. The students were then: (i) introduced to two simple water quality testing methods for nitrates, (ii) required to hypothesize as to which method will likely be "better" in application, and (iii) asked to practice using these two methods under laboratory conditions. Following practice, the students were asked to discuss their hypotheses relative to what was observed during the practice focusing on which testing method was more accurate and/or precise. The students were then encouraged to bring water samples from their home water system (many of which are on private wells) to analyze within groups. At the end of the week, the students shared their experience in this educational effort, as well as the resulting nitrate data from numerous groundwater wells (as collected by the students). Following these discussions the data were added to an online database housed on a wiki sponsored by the Notre Dame Extended Research Community (http://wellhead.michianastem.org/home). These data were plotted using the free service MapAList to visually demonstrate to the students the spatial distribution of the data and how their results have

    Selected K--12 public school science educators in 14 eastern North Carolina counties were surveyed to examine their perceptions of their undergraduate preparation programs with regard to instructing students with learning disabilities in the regular classroom. A quantitative study, this research examined science educator preparedness in instructing students with learning disabilities by evaluating educator perception in regard to mainstrearned and inclusive educational settings. Specifically, two null hypotheses were tested. Null hypothesis I stated a significant difference does not exist between selected North Carolina K--12 science educators' perceptions of their undergraduate teacher education preparation programs and their perceptions of their abilities to instruct students needing accommodations on behalf of their learning disabilities in mainstrearned or inclusive settings. Participants' responses to perception as well as value statements regarding opinions, adaptations, and undergraduate training with respect to mainstreaming and inclusion were evaluated through t-test analyses of 22 Likert-scale items. Null hypothesis 1 was not accepted because a statistically significant difference did exist between the educators' perceptions of their undergraduate training and their perceived abilities to instruct students with learning disabilities in mainstreamed or inclusive settings. Null hypothesis 2 stated a significant difference does not exist between selected North Carolina K--12 science educators' attained educational level; grade level currently taught, supervised or chaired; and years of experience in teaching science, supervising science education, and/or chairing science departments in selected North Carolina public schools and their opinions of their undergraduate teacher education program with regard to instructing students with learning disabilities in mainstreamed or inclusive educational settings. Null hypothesis 2 was evaluated through an analysis of

    2016-06-01

    Full Text Available The introduction of computer programming in K-12 has become mainstream in the last years, as countries around the world are making coding part of their curriculum. Nevertheless, there is a lack of empirical studies that investigate how learning to program at an early age affects other school subjects. In this regard, this paper compares three quasi-experimental research designs conducted in three different schools (n=129 students from 2nd and 6th grade, in order to assess the impact of introducing programming with Scratch at different stages and in several subjects. While both 6th grade experimental groups working with coding activities showed a statistically significant improvement in terms of academic performance, this was not the case in the 2nd grade classroom. Notable disparity was also found regarding the subject in which the programming activities were included, as in social studies the effect size was double that in mathematics.

  11. Achieving 50% Energy Savings in New Schools, Advanced Energy Design Guides: K-12 Schools (Brochure)

    Energy Technology Data Exchange (ETDEWEB)

    2014-09-01

    This fact sheet summarizes recommendations for designing elementary, middle, and high school buildings that will result in 50% less energy use than conventional new schools built to minimum code requirements. The recommendations are drawn from the Advanced Energy Design Guide for K-12 School Buildings, an ASHRAE publication that provides comprehensive recommendations for designing low-energy-use school buildings (see sidebar). Designed as a stand-alone document, this fact sheet provides key principles and a set of prescriptive design recommendations appropriate for smaller schools with insufficient budgets to fully implement best practices for integrated design and optimized performance. The recommendations have undergone a thorough analysis and review process through ASHRAE, and have been deemed the best combination of measures to achieve 50% savings in the greatest number of schools.

    1975-03-01

    A single-site mutant of Escherichia coli K-12 able to grow in minimal medium in the presence of D-serine at 30 C but not at 42 C was isolated. The mutant forms a D-serine deaminase that is much more sensitive to thermal denaturation in vitro at temperatures above but not below 47 C than that of the wild type. No detectable enzyme is formed by the mutant at 42 C, however, and very little is formed at 37 C. The mutant enzyme is probably more sensitive to intracellular inactivation at high temperatures than the wild-type enzyme. The mutation lies in the dsdA region. The mutant also contains a dsdO mutation, which does not permit hyperinduction of D-serine deaminase synthesis.

    For a 'user' there are several genres of citizen science activities one can enlist themselves in, from microtasked analytics to data collection. Often times design conversation for these efforts are focused around the goal of collecting high quality data for an urgent scientific question. However, there is much to be discussed around the opportunity to expand upon the interaction experience of the 'user'. This is particularly relevant in the integration of citizen science in the classroom. Here we explore the role of citizen science in formal K-12 science education through the lens of "Project Based Learning", examining design challenges in classroom adoption (including standards alignment) as well as interaction design focused around long term user/student motivation and engagement in the science exploration.

    A novel photochromic nanocomposite film containing polyoxotungstoeuropate K 12[EuP 5W 30O 110] entrapped in polyvinylpyrrolidone has been prepared through a spin-on coating technique. Thus-obtained amorphous nanocomposite film was characterized by IR spectra, UV-vis absorption spectra, XRD, SEM, TG-DTA, and ESR. Results show that polyoxotungstoeuropate interacts with polyvinylpyrrolidone strongly and disperses homogeneously in the matrix. The composite film exhibits good photochromic properties. When irradiated with UV light, the transparent film changes from colorless to blue. Then, bleaching occurs when the film is in contact with ambient air or O 2 in the dark. The photochromism of the composite film is due to charge transfer by reduction of polyoxotungstoeuropate and oxidation of polyvinylpyrrolidone.

    2012-02-01

    Research on teaching to the test in K-12 settings has documented the lack of generalized understanding of underlying principles in tested subjects. This is similar to the experience of physics students who can complete computational problems without conceptual understanding. The PER community is well aware of the importance of explicit representations of learning goals as well as the role of the formative assessment process, especially feedback and self assessment, in promoting or deterring students' engagement and willingness to take responsibility for their own learning. Key principles from socio-cultural learning theory and research on motivation are summarized and used to identify instructional and assessment practices that hold the most promise for engaging students in developing deep conceptual understanding.

    A plasmid pSDK-1 containing the Escherichia coli phosphofructokinase-1 (EC 2.7.1. 11) gene (pfkA) was constructed and transferred into Acidithiobacillus thiooxidans Tt-Z2 by conjugation. The transfer frequency of plasmid from E. coli to Tt-Z2 was 2.6 x 10(-6). More than 68% of Tt-Z2 cells carried the recombinant plasmids after being cultured for 50 generations without selective pressure, which showed that pSDK-1 was maintained consistently in Tt-Z2. The pfkA gene from E. coli could be expressed in this obligately autotrophic bacterium but the enzyme activity (14 U/g was lower than that in E. coli (K-12: 86 U/g; DF1010 carrying plasmid pSDK-1: 97 U/g). In th presence of glucose, the Tt-Z2 transconjugant consumed glucose leading to a better growth yield.

    with the exponential growth phase, 1.9% of the genes showed a consistent up- or downregulation by a factor greater than two, and that 10% of the E. coli genome is significantly differentially expressed. The functions of the genes induced in these conditions correspond to stress response as well as energy production...... that the biofilm lifestyle, although sharing similarities with the stationary growth phase, triggers the expression of specific sets of genes. Using gene disruption of 54 of the most biofilm-induced genes followed by a detailed phenotypic study, we validated the biological relevance of our analysis and showed......The formation of biofilm results in a major lifestyle switch that is thought to affect the expression of multiple genes and operons. We used DNA arrays to study the global effect of biofilm formation on gene expression in mature Escherichia coli K-12 biofilm. We show that, when biofilm is compared...

    BioEYES, a nonprofit outreach program using zebrafish to excite and educate K-12 students about science and how to think and act like scientists, has been integrated into hundreds of under-resourced schools since 2002. During the week-long experiments, students raise zebrafish embryos to learn principles of development and genetics. We have analyzed 19,463 participating students' pre- and post-tests within the program to examine their learning growth and attitude changes towards science. We found that at all grade levels, BioEYES effectively increased students' content knowledge and produced favorable shifts in students' attitudes about science. These outcomes were especially pronounced in younger students. Having served over 100,000 students, we find that our method for providing student-centered experiences and developing long-term partnerships with teachers is essential for the growth and sustainability of outreach and school collaborations.

    Science museums engage in a wide range of activities not apparent to exhibit hall visitors. Many of them can support research outreach to public and K-12 teachers and students. In addition to exhibits in science centers, and demonstrations on topics like electricity or cryogenics, science museums offer courses for children and adults, out-of-school programs for students, teacher professional development; some do K-12 curriculum development and some run science magnet schools. In recent years science museums have increased their capacity to communicate with the public about current research. The Museum of Science, for instance, created a Current Science and Technology Center in 2001 dedicated to science in the news and current research developments. Through this Center, the Museum partnered with Harvard University to provide a wide range of public engagement activities as part of Harvard's Nanoscale Science and Engineering Center focused on the Science of Nanoscale Systems and their Device Applications. In the past five years a number of new collaborations among science museums have developed, many in partnership with researchers and research centers. Perhaps the largest or these, the Nanoscale Informal Science Education Network (NISE Net) was launched in 2005 with funding from the National Science Foundation. The NISE Net links informal science education organizations together and to university research centers to raise the capacity of all the participant organizations to increase public awareness, understanding, and engagement with nanoscale science, engineering, and technology. Nearly 300 informal educational organizations in every state nationwide make use of NISE Net's educational materials, professional development, national and regional meetings, and online resources. NISE Net is an open source network with all of its materials freely available to everyone.

    2015-01-01

    An atypical Actinobacillus pleuropneumoniae serovar 12 strain, termed QAS106, was isolated from a clinical case of porcine pleuropneumonia in Japan. An immunodiffusion (ID) test identified the strain as serovar 12. However, the ID test also demonstrated that strain QAS106 shared antigenic determinants with both the serovar 3 and 15 reference strains. Strain QAS106 was positive in the capsular serovar 12-specific polymerase chain reaction (PCR) assay, while the PCR toxin gene profiling and omlA PCR typing assays indicated that strain QAS106 was similar to serovar 3. The nucleotide sequence of the 16S ribosomal DNA (rDNA) of strain QAS106 was identical with that of serovars 3 and 12, but it showed 99.7% identity with that of serovar 15. Nucleotide sequence analysis revealed that genes involved in biosynthesis of the capsular polysaccharide (CPS) of strain QAS106 were identical to those of serovar 12 at the amino acid level. On the other hand, strain QAS106 would express putative proteins involved in the biosynthesis of lipopolysaccharide (LPS) O-polysaccharide (O-PS), the amino acid sequences of which were identical or nearly identical to those of serovars 3 and 15. In conclusion, strain QAS106 should be recognized as K12:O3, even though typical serovar 12 strains are K12:O12. The emergence of an atypical A. pleuropneumoniae serovar 12 strain expressing a rare combination of CPS and O-PS antigens would hamper precise serodiagnosis by the use of either CPS- or LPS-based serodiagnostic methodology alone. © 2014 The Author(s).

    The C and D cell cycle periods of seven Escherichia coli K-12 strains and three E, coli B/r strains were determined by computer simulation of DNA histograms obtained by flow cytometry of batch cultures grown at several different generation times. To obtain longer generation times two of the K-12...... strains were cultivated at several different dilution rates in glucose-limited chemostats. The replication period (C period) was found to be similar in K-12 and B/r strains grown at similar generation times. At generation times below 60 min the C period was constant; above 60 min it increased linearly...... with increasing generation time. The period from termination of replication to cell division (D period) was more variable. It was much shorter in B/r than in K-12 strains. Like the C period it was relatively constant at generation times below 60 min and it increased with increasing generation times at longer...

  8. Are We Preparing the Next Generation? K-12 Teacher Knowledge and Engagement in Teaching Core STEM Practices

    OpenAIRE

    Nadelson, Louis; Seifert, Anne; Hendricks, J. Kade

    2015-01-01

    Background: Several of the recent reform efforts in K-12 STEM education (e.g. Next Generation Science Standards [NGSS and Common Core State Standards-Mathematics [CCSS-M]) have included significant emphasis on the practices of STEM. We argue that K-12 teachers' ability to effectively engage their students in these core STEM practices is fundamental to the success of potential and current engineering students and their subsequent careers as engineers. Practices such as identifying problems, mo...

    DNA sequence and expressional analyses of the gcd gene of Escherichia coli K-12 W3110 revealed that two promoters that were detected were regulated negatively by cyclic AMP and positively by oxygen. Sequence conservation of the gcd gene between E. coli K-12 W3110 and PPA42 suggests that glucose dehydrogenase is required for the E. coli cells, even though it ordinarily exists as an apoprotein.

    Science literacy is a major goal of science educational reform (NRC, 1996; AAAS, 1998; NCLB Act, 2001). Some believe that teaching science only requires pedagogical content knowledge (PCK). Others believe doing science requires knowledge of the methodologies of scientific inquiry (NRC, 1996). With these two mindsets, the challenge for science educators is to create models that bring the two together. The common ground between those who teach science and those who do science is science communication, an interactive process that galvanizes dialogue among scientists, teachers, and learners in a rich ambience of mutual respect and a common, inclusive language of discourse . The dialogue between science and non-science is reflected in the polarization that separates those who do science and those who teach science, especially as it plays out everyday in the science classroom. You may be thinking, why is this important? It is vital because, although not all science learners become scientists, all K-12 students are expected to acquire science literacy, especially with the implementation of the No Child Left Behind Act of 2001 (NCLB). Students are expected to acquire the ability to follow the discourse of science as well as connect the world of science to the context of their everyday life if they plan on moving to the next grade level, and in some states, to graduate from high school. This paper posits that science communication is highly effective in providing the missing link for K-12 students cognition in science and their attainment of science literacy. This paper will focus on the "Science For Our Schools" (SFOS) model implemented at California State Univetsity, Los Angeles (CSULA) as a project of the National Science Foundation s GK-12 program, (NSF 2001) which has been a huge success in bridging the gap between those who "know" science and those who "teach" science. The SFOS model makes clear the distinctions that identify science, science communication, science

  15. Raising Climate Literacy of K-12 Teachers with Datastreme Earth's Climate System

    The American Meteorological Society (AMS) DataStreme Project is a free professional development program for in-service K-12 teachers, in which they gain considerable subject matter content and confidence in Earth science instruction. DataStreme Atmosphere, Ocean, and Earth's Climate System (ECS) are offered each fall and spring semester by Local Implementation Teams (LITs) across the country in coordination with a team of AMS Education Program scientists and educators who develop instructional materials, provide logistical support to the LITs, and administer the project. The 3-member LITs mentor about 8 teachers and in some instances an emergency manager, per semester through a given DataStreme course. Teachers may receive 3 tuition-free graduate credits through State University of New York's The College at Brockport upon completion of each DataStreme course. DataStreme is in close alignment with A Framework for K-12 Science Education and the Next Generation Science Standards (NGSS). Investigating the scientific basis of the workings of Earth's atmosphere, ocean, and climate system follows the cross-cutting theme of the Framework and the NGSS and is the cornerstone of the DataStreme courses. In particular, DataStreme ECS explores the fundamental science of Earth's climate system and addresses the societal impacts relevant to today's teachers and students. The course utilizes resources from respected organizations, such as the IPCC and U.S. Global Change Research Program. Key to the NGSS is that students learn disciplinary core ideas in the context of science and engineering practices. In order for the students to learn in this way, the AMS believes that it is important to train the teachers in this context. DataStreme ECS emphasizes investigation of real-word and current NASA and NOAA data. Participants also are made aware of NASA's EdGCM, a research-grade Global Climate Model where they can explore various future climate scenarios in the same way that actual

    In the classroom, the interaction between students, teachers, and datasets is becoming more game like. Software such as GoogleEarth allow students to interact with data on a more personal level; allowing them the dynamically change variables, move arbitrarily, and personalize their experience with the datasets. As this becomes more immersive, traditional software control such as keyboard and mouse begin to hold the student back in terms of intuitive interfacing with the data. This is a problem that has best been tackled by modern gaming systems such as the Wii, XBox 360, and Playstation 3 Systems. By utilizing the solutions given by these gaming systems, it is possible to further a students immersion with a system. Through an NSF ITEST (Information and Technology Experiences for Students and Teachers) grant, researchers at the University of Maine have experimented with using the game controller that is used for interacting with the Nintendo Wii (often called a Wiimote) with existing geodynamic systems in an effort to eases interaction with these systems. Since these game controllers operate using Bluetooth, a common protocol in computing, Wiimotes can easily communicate with existing laptop computers that are issued to Maine students. This paper describes the technical requirements, setup, and usage of Wiimotes as an input device to complex geodynamical systems for use in the K-12 classroom.
