Relevance of in vitro tests of adhesive and composite dental materials, a review in 3 parts. Part 1: Approval requirements and standardized testing of composite materials according to ISO specifications

The first part of this three-part review on the relevance of laboratory testing of composites and adhesives deals with approval requirements for composite materials. We compare the in vivo and in vitro literature data and discuss the relevance of in vitro analyses. The standardized ISO protocols are presented, with a focus on the evaluation of physical parameters. These tests all have a standardized protocol that describes the entire test set-up. The tests analyse flexural strength, depth of cure, susceptibility to ambient light, color stability, water sorption and solubility, and radiopacity. Some tests have a clinical correlation. A high flexural strength, for instance, decreases the risk of fractures of the marginal ridge in posterior restorations and incisal edge build-ups of restored anterior teeth. Other tests do not have a clinical correlation or the threshold values are too low, which results in an approval of materials that show inferior clinical properties (e.g., radiopacity). It is advantageous to know the test set-ups and the ideal threshold values to correctly interpret the material data. Overall, however, laboratory assessment alone cannot ensure the clinical success of a product.

English language learners and standardized testing in an urban senior high school

The primary purpose of this study was to examine the influences of literacy variables on high-stakes test performance including: (a) student achievement on the Metropolitan Achievement Test, Seventh Edition (MAT-7) as correlated to the high-stakes test such as the FCAT examination and (b) the English language proficiency attained by English Language Learners (ELL) students when participating in, or exiting from English Speakers of Other Languages (ESOL) program as determined by the Limited English Proficient (LEP) committee. ^ Two one-sample Chi-square tests were conducted to investigate the relationship between passing the MAT-7 Reading and Language examinations and the FCAT-SSS Reading Comprehension and FCAT-NRT examinations. In addition, 2x2 Analyses of Variance (ANOVAs) were conducted to address the relationship between the time ELL students spent in the ESOL program and the level of achievement on MAT-7 Reading and Language examinations and the FCAT-SSS Reading Comprehension and FCAT-NRT. ^ Findings of this study indicated that more ELL students exit the program based on the LEP committee decisions than by passing the MAT-7. The majority of ELL students failed the 10th grade FCAT, the passing of which is needed for graduation. A significant number of ELL students failed, even when passing the MAT-7 or being duly exited through the decision of the LEP committee. The data also indicated that ELL students who exited the ESOL program in six semesters or fewer had higher FCAT scores than those who exited the program in seven semesters or more. The MAT-7 and the decision of the LEP committee were shown to be ineffective as predictors of success on the FCAT. ^ Further research to determine the length of time a student in the ESOL program uses English to read, write, and speak should be conducted. Additionally, the development of a new assessment instrument to better predict student success should be considered. However, it should be noted that the results of this study are limited to the context in which it was conducted and does not warrant generalizations beyond that context. ^

Stereotype threat and the standardized testing experiences of African American children at an urban elementary school

Stereotype threat (Steele & Aronson, 1995) refers to the risk of confirming a negative stereotype about one’s group in a particular performance domain. The theory assumes that performance in the stereotyped domain is most negatively affected when individuals are more highly identified with the domain in question. As federal law has increased the importance of standardized testing at the elementary level, it can be reasonably hypothesized that the standardized test performance of African American children will be depressed when they are aware of negative societal stereotypes about the academic competence of African Americans. This sequential mixed-methods study investigated whether the standardized testing experiences of African American children in an urban elementary school are related to their level of stereotype awareness. The quantitative phase utilized data from 198 African American children at an urban elementary school. Both ex-post facto and experimental designs were employed. Experimental conditions were diagnostic and non-diagnostic testing experiences. The qualitative phase utilized data from a series of six focus group interviews conducted with a purposefully selected group of 4 African American children. The interview data were supplemented with data from 30 hours of classroom observations. Quantitative findings indicated that the stereotype threat condition evoked by diagnostic testing depresses the reading test performance of stereotype-aware African American children (F[1, 194] = 2.21, p < .01). This was particularly true of students who are most highly domain-identified with reading (F[1, 91] = 19.18, p < .01). Moreover, findings indicated that only stereotype-aware African American children who were highly domain-identified were more likely to experience anxiety in the diagnostic condition (F[1, 91] = 5.97, p < .025). Qualitative findings revealed 4 themes regarding how African American children perceive and experience the factors related to stereotype threat: (1) a narrow perception of education as strictly test preparation, (2) feelings of stress and anxiety related to the state test, (3) concern with what “others” think (racial salience), and (4) stereotypes. A new conceptual model for stereotype threat is presented, and future directions including implications for practice and policy are discussed.

No Child Left Behind, Stereotype Threat, and the Standardized Testing of African American Third-Graders

Stereotype threat theory proposes that the possibility of being judged in terms of a negative stereotype in a particular domain negatively affects one’s performance. The proposed mixed-methods research will investigate the influences of stereotype threat on African American third-graders in a post-No Child Left Behind environment.

“I’m Trying To Bring the Scores of My School Up, Man!" Standardized Testing, Stereotypes, and High-Performing African American Elementary School Students

This qualitative study investigated factors that produced or perpetuated standardized test-based stereotype threat effects for a group of African American children. Findings revealed 4 themes: a perception of education as strictly test preparation, test-based stress and anxiety, racial salience, and stereotypes. Implications for practice and policy are discussed.

A multiple case study of NAPLAN numeracy testing of Year 9 students in three Queensland secondary schools

This thesis reports on a multiple case study of the actions of three Queensland secondary schools in the context of Year 9 NAPLAN numeracy testing, focusing on their administrative practices, curriculum, pedagogy and assessment. It was established that schools have found it both challenging and costly to operate in an environment of educational reform generally, and NAPLAN testing in particular. The lack of a common understanding of numeracy and the substantial demands of implementing the Australian Curriculum have impacted on schools' ability to prepare students appropriately for NAPLAN numeracy tests. It was concluded that there is scope for schools to improve their approaches to NAPLAN numeracy testing in a way that maximises learning as well as test outcomes.

Attempting to improve standardized test results using Study Islands' web-based mastery program

State standardized testing has always been a tool to measure a school’s performance and to help evaluate school curriculum. However, with the school of choice legislation in 1992, the MEAP test became a measuring stick to grade schools by and a major tool in attracting school of choice students. Now, declining enrollment and a state budget struggling to stay out of the red have made school of choice students more important than ever before. MEAP scores have become the deciding factor in some cases. For the past five years, the Hancock Middle School staff has been working hard to improve their students’ MEAP scores in accordance with President Bush's “No Child Left Behind” legislation. In 2005, the school was awarded a grant that enabled staff to work for two years on writing and working towards school goals that were based on the improvement of MEAP scores in writing and math. As part of this effort, the school purchased an internet-based program geared at giving students practice on state content standards. This study examined the results of efforts by Hancock Middle School to help improve student scores in mathematics on the MEAP test through the use of an online program called “Study Island.” In the past, the program was used to remediate students, and as a review with an incentive at the end of the year for students completing a certain number of objectives. It had also been used as a review before upcoming MEAP testing in the fall. All of these methods may have helped a few students perform at an increased level on their standardized test, but the question remained of whether a sustained use of the program in a classroom setting would increase an understanding of concepts and performance on the MEAP for the masses. This study addressed this question. Student MEAP scores and Study Island data from experimental and comparison groups of students were compared to understand how a sustained use of Study Island in the classroom would impact student test scores on the MEAP. In addition, these data were analyzed to determine whether Study Island results provide a good indicator of students’ MEAP performance. The results of the study suggest that there were limited benefits related to sustained use of Study Island and gave some indications about the effectiveness of the mathematics curriculum at Hancock Middle School. These results and implications for instruction are discussed.

Stereotype Threat and the Standardized Test Performance of Black Children: When Does the Threat Become a Relevant Performance Inhibitor?

As Black students become more invested in the outcome of standardized tests, stereotypes become salient, subsequently depressing performance (Steele, 1997). As federal law has increased the importance of standardized testing at the elementary level, research is needed to determine when the stereotype threat becomes a relevant performance inhibitor.

Letting go of Neo-Liberalism (with some help from Michel Foucault)

Neo-liberalism has become one of the boom concepts of our time. From its original reference point as a descriptor of the economics of the “Chicago School” such as Milton Friedman, or authors such as Friedrich von Hayek, neo-liberalism has become an all-purpose descriptor and explanatory device for phenomena as diverse as Bollywood weddings, standardized testing in schools, violence in Australian cinema, and the digitization of content in public libraries. Moreover, it has become an entirely pejorative term: no-one refers to their own views as “neo-liberal”, but it rather refers to the erroneous views held by others, whether they acknowledge this or not. Neo-liberalism as it has come to be used, then, bears many of the hallmarks of a dominant ideology theory in the classical Marxist sense, even if it is often not explored in these terms. This presentation will take the opportunity provided by the English language publication of Michel Foucault’s 1978-79 lectures, under the title of The Birth of Biopolitics, to consider how he used the term neo-liberalism, and how this equates with its current uses in critical social and cultural theory. It will be argued that Foucault did not understand neo-liberalism as a dominant ideology in these lectures, but rather as marking a point of inflection in the historical evolution of liberal political philosophies of government. It will also be argued that his interpretation of neo-liberalism was more nuanced and more comparative than the more recent uses of Foucault in the literature on neo-liberalism. It will also look at how Foucault develops comparative historical models of liberal capitalism in The Birth of Biopolitics, arguing that this dimension of his work has been lost in more recent interpretations, which tend to retro-fit Foucault to contemporary critiques of either U.S. neo-conservatism or the “Third Way” of Tony Blair’s New Labour in the UK.

Alternatives to the World Bank’s strategies for education and development

Over the past several decades, policy has become increasingly global. In economics, for example, policy has followed the so-called Washington Consensus of privatization, liberalization, and deregulation. In education, global policy has included the proliferation of strategies including standardized testing, paraprofessional teachers, user fees, and privatization. There are many problems with these neoliberal policies. Foremost among them, is the havoc they wreak on the lives of so many children and adults. Poverty, inequality, and myriad associated problems have reached new heights in this neoliberal era. Moreover, these policies have been adopted uncritically and alternative policies have been ignored, which leads to our focus here.

Yutori Kyoiku and the uncertainty of recent neo-liberal reforms in Japanese higher education

This paper draws upon the current situation within Japanese Higher Education. In particular the paper focuses on educational reforms and how they relate to the notions of Yutori Kyoiku which constituted a major attempt by Japanese education to develop individual student capacity. A clear subtext of the recent neo-liberal reform agenda is a desire to incorporated free-market ideals into the Japanese educational system. This paper raises several important problems connected to the reforms such as the decrease in classroom hours, changes to the contents of textbooks and a growing discrepancy in academic skills between students in different localities. These education reforms have impacted on notions of Yutori Kyoiku through the continuation of nationally standardized testing and changes directed at controlling the practices of classroom teachers. While acknowledging the current Japanese cabinet’s (DP) education policy has been inherited from an earlier LDP government, the paper points to similarities between the current reforms and the iconic Meiji era reforms of the late 1800s.

Towards fairer assessment

Drawing on the largest Australian collection and analysis of empirical data on multiple facets of Aboriginal and Torres Strait Islander education in state schools to date, this article critically analyses the systemic push for standardized testing and improved scores, and argues for a greater balance of assessment types by providing alternative, inclusive, participatory approaches to student assessment. The evidence for this article derives from a major evaluation of the Stronger Smarter Learning Communities. The first large-scale picture of what is occurring in classroom assessment and pedagogy for Indigenous students is reported in this evaluation yet the focus in this article remains on the issue of fairness in student assessment. The argument presented calls for “a good balance between formative and summative assessment” (OECD, Synergies for Better Learning An International Perspective on Evaluation and Assessment, Pointers for Policy Development, 2013) at a time of unrelenting high-stakes, standardized testing in Australia with a dominance of secondary as opposed to primary uses of NAPLAN data by systems, schools and principals. A case for more “intelligent accountability in education” (O’Neill, Oxford Review of Education 39(1):4–16, 2013) together with a framework for analyzing efforts toward social justice in education (Cazden, International Journal of Educational Psychology 1(3):178–198, 2012) and fairer assessment make the case for more alternative assessment practices in recognition of the need for teachers’ pedagogic practice to cater for increased diversity.

Current Care Guidelines for Cardiopulmonary Resuscitation : Implementation, skills and attitudes

Background: The national resuscitation guidelines were published in Finland in 2002 and are based on international guidelines published in 2000. The main goal of the national guidelines, available on the Internet free of charge, is early defibrillation by nurses in an institutional setting. Aim: To study possible changes in cardiopulmonary resuscitation (CPR) practices, especially concerning early defibrillation, nurses and students attitudes of guideline implementation and nurses and students ability to implement the guideline recommendations in clinical practices after publication of the Current Care (CC) guidelines for CPR 2002. Material and methods: CPR practices in Finnish health centres; especially concerning rapid defibrillation programmes, as well as the implementation of CC guidelines for CPR was studied in a mail survey to chief physicians of every health centre in Finland (Study I). The CPR skills using an automated external defibrillator (AED) were compared in a study including Objective stuctured clinical examination (OSCE) of resuscitation skills of nurses and nursing students in Finnish and Swedish hospital and institution (Studies II, III). Attitudes towards CPR-D and CPR guidelines among medical and nursing students and secondary hospital nurses were studied in surveys (Studies IV, V). The nurses receiving different CPR training were compared in a randomized trial including OSCE of CPR skills of nurses in Finnish Hospital (Study VI). Results: Two years after the publication, 40.7% of Finnish health centres used national resuscitation guidelines. The proportion of health centres having at least one AED (66%) and principle of nurse-performed defibrillation without the presence of a physician (42%) had increased. The CPR-D training was estimated to be insufficient regarding basic life support and advanced life support in the majority of health centres (Study I). CPR-D skills of nurses and nursing students in two specific Swedish and Finnish hospitals and institutions (Study II and III) were generally inadequate. The nurses performed better than the students and the Swedish nurses surpassed the Finnish ones. Geriatric nurses receiving traditional CPR-D training performed better than those receiving an Internet-based course but both groups failed to defibrillate within 60 s. Thus, the performance was not satisfactory even two weeks after traditional training (Study VI). Unlike the medical students, the nursing students did not feel competent to perform procedures recommended in the cardiopulmonary resuscitation guidelines including the defibrillation. However, the majority of nursing students felt confident about their ability to perform basic life support. The perceived ability to defibrillate correlated significantly with a positive attitude towards nurse-performed defibrillation and negatively with fear of damaging the patient s heart by defibrillation (Study IV). After the educational intervention, the nurses found their level of CPR-D capability more sufficient than before and felt more confident about their ability to perform defibrillation themselves. A negative attitude toward defibrillation correlated with perceived negative organisational attitudes toward cardiopulmonary resuscitation guidelines. After CPR-D education in the hospital, the majority (64%) of nurses hesitated to perform defibrillation because of anxiety and 27 % hesitated because of fear of injuring the patient. Also a negative personal attitude towards guidelines increased markedly after education (Study V). Conclusions: Although a significant change had occurred in resuscitation practices in primary health care after publication of national cardiopulmonary resuscitation guidelines the participants CPR-D skills were not adequate according to the CPR guidelines. The current way of teaching is unlikely to result in participants being able to perform adequate and rapid CPR-D. More information and more frequent training are needed to diminish anxiety concerning defibrillation. Negative beliefs and attitudes toward defibrillation affect the nursing students and nurses attitudes toward cardiopulmonary resuscitation guidelines. CPR-D education increased the participants self-confidence concerning CPR-D skills but it did not reduce their anxiety. AEDs have replaced the manual defibrillators in most institutions, but in spite of the modern devices the anxiety still exists. Basic education does not provide nursing students with adequate CPR-D skills. Thus, frequent training in the workplace has vital importance. This multi-professional program supported by the administration might provide better CPR-D skills. Distance learning alone cannot substitute for traditional small-group learning, tutored hands-on training is needed to learn practical CPR-D skills. Standardized testing would probably help controlling the quality of learning. Training of group-working skills might improve CPR performance.

Movimentos discursivos nas vozes dos sujeitos da Prova Rio

A partir de 2009, a Prefeitura Municipal do Rio de Janeiro inicia a aplicação sistemática de provas bimestrais de Língua Portuguesa e Matemática formuladas Por órgãos especializados em avaliações padronizadas. Tais avaliações, com efeito, materializam camadas de um discurso educacional que vincula qualidade à mensuração de conhecimento em determinados componentes curriculares. Assumindo um modelo de reprodução das avaliações em Larga Escala, a prefeitura enfatiza os resultados mensuráveis nas avaliações sistemáticas, legitimando-os como verdadeiros paradigmas metonímicos da qualidade da educação carioca, enfatizados pela SME em seu discurso virtual disponível em sua página oficial na internet. A partir da constatação de que o discurso é uma prática social, ancorado nas contribuições de Teun A. Van Dijk, Norman Fairclough, Boaventura Sousa de santos entre outros, é traçado nesta pesquisa um percurso de investigação que dialoga com a Análise Crítica do Discurso na busca por elementos discursivos nos textos de professores e alunos acerca dessa cultura de testes padronizados que possam apontar a fluidez dos discursos de protestos que atravessam o cotidiano escolar.
