Windows,Bridges and Mirrors: Building Culturally Responsive Early Childhood Classrooms through the Integration of Literacy and the Arts

This article investigates how instructors can utilize the integration of early literacy skills and the arts to cultivate the appreciation and celebration of cultures in early childhood classrooms. The theoretical framework is developed through three personal accounts establishing a rationale for the importance of a viable home to school connection for young children. Finally, the suggested activities support the transference of theory into classroom practice.     

Design and implementation of an intelligent virtual environment for improving speaking and listening skills

In this paper, we present an intelligent architecture, called intelligent virtual environment for language learning, with embedded pedagogical agents for improving listening and speaking skills of non-native English language learners. The proposed architecture integrates virtual environments into the Intelligent Computer-Assisted Language Learning. This architecture supports visual, auditory, and haptic channels of interaction. It allows pedagogical ideas about language skills to be implemented and validated with a minimum design time. Moreover, we design a computational model to evaluate learner's proficiency level, and an automatic adaptation mechanism which adjusts to the learner's learning curve. We have implemented two scenarios based on the proposed architecture to teach learners how to communicate in public places such as airports and TV stores. Inputs to this system include learner's speech and hand motion, and outputs include graphical scenes, force feedback, and speech by a few embodied agents. Throughout interactions, agents discover the proficiency level of the learner and customize the level of communication complexity accordingly. The system is tested on 10 subjects. Experimental results show 14% increase in the number of proper replies, 3% decrease in grammatical errors, 16% decrease in pronunciation duration, and 11% increase in learners' proficiency level within three trials.     

Strategies of resistance to anti-Islamic representations among Australian Muslim women: an intersectional approach

ABSTRACT

Contemporary anti-Islamic discourses in Australia construct Islam as an uncivilised belief system and its Muslim followers as homogenous unassimilable Others. Within these discourses, the diversity among Muslim women has been overshadowed, and they are constructed as a monolithic ‘veiled’ woman. Drawing on 20 conversational interviews with veiled and unveiled Australian Muslim women from various cultural backgrounds, this paper explores the diverse ways in which Muslim women resist and challenge anti-Islamic discourses on Islam, Muslims and Muslim women. Guided by intersectional theories on identity and resistance, our analysis show that the women drew on discursive and performative strategies to contest anti-Islamic representations that homogenise and vilify Muslims and construct Muslim women as veiled and oppressed. The findings also show that the ways in which women contested hegemonic anti-Islamic representations were diverse and informed by intersecting power and social locations, including race, ethnicity, gender and sexuality. Implications for research on resistance and identity negotiations of minority groups are discussed.     

How Do Norwegian Reception Schools Cater to the Academic and Integrational Needs of Newly Arrived Minority Language Pupils: Cases From Two Municipalities

This article explores the perceptions and experiences of the professionals about integrational and academic programs for newly arrived minority language pupils in elementary reception classes in two Norwegian municipalities: Oslo and Trondheim. The data were collected through interviews, field conversations, and available relevant documents. The head teachers, subject coordinators, and reception teachers were interviewed. Framed by activity theory, the article offers a combinative analysis of all aspects of the reception classes. The findings reveal the complex layers of challenges built into the process of integrational and academic programs for newly arrived migrant pupils in the reception classes.

Written for teachers, who generally lack a sufficient knowledge of how people learn, Pritchard's book aims at enhancing the effectiveness and efficiency of education through raising teachers' understanding of learning theory. However, it does not do so very effectively: even if you are a keen teacher, you will probably find only parts of much interest or use. Mohammad Ali Salmani Nodoushan     

Extraction of DNA suitable for PCR applications from mature leaves of Mangifera indica L.

Good quality deoxyribonucleic acid (DNA) is the pre-requisite for its downstream applications. The presence of high concentrations of polysaccharides, polyphenols, proteins, and other secondary me- tabolites in mango leaves poses problem in getting good quality DNA fit for polymerase chain reaction (PCR) applications. The problem is exacerbated when DNA is extracted from mature mango leaves. A reliable and modified protocol based on the cetyl- trimethylammonium bromide (CTAB) method for DNA extraction from mature mango leaves is described here. High concentrations of inert salt were used to remove polysaccharides; Polyvinylpyrrolidone (PVP) and β-mercaptoethanol were employed to manage phenolic compounds. Extended chloroform-isoamyl alcohol treatment followed by RNase treatment yielded 950?1050 μg of good quality DNA, free of protein and RNA. The problems of DNA degradation,contamination, and low yield due to irreversible binding of phenolic compounds and coprecipitation of polysaccharides with DNA were avoided by this method. The DNA isolated by the modified method showed good PCR amplification using simple se- quence repeat (SSR) primers. This modified protocol can also be used to extract DNA from other woody plants having similar problems.     

Teaching and Learning Regimes: Implicit theories and recurrent practices in the enhancement of teaching and learning through educational development programmes

This paper uses the concept of teaching and learning regimes (TLRs) to help explore a set of questions about why some academic staff in universities thrive on and benefit from accredited programmes designed to improve HE learning and teaching practices ("educational development programmes") whilst others experience periods of resistance or some drop out altogether. "TLR" is a shorthand term for a constellation of rules, assumptions, practices and relationships related to teaching and learning issues in higher education. These include aspects of the following salient to teaching and learning, each of which we elaborate and illustrate in the paper: identities in interaction, power relations, codes of signification, tacit assumptions, rules of appropriateness, recurrent practices, discursive repertoires, implicit theories of learning and of teaching. The argument presented here is that academic staff on educational development programmes ("participants") bring to programmes sets of assumptions and practices rooted in TLRs. Educational development programmes themselves instantiate TLRs which may be more, or less, compatible with those of individual participants. Where there are incongruities between the two they need not be fatal if participants are able to, or are encouraged to, surface and reflect on previously tacit assumptions embedded in their TLRs. Similarly, there may not be a problem if participants are able to exercise discretion over the application of aspects of different regimes; applying them in different contexts as appropriate. Evidence from participants' writing, participant observation, secondary sources and data from eight interviews inform the paper and form the basis for illustrative vignettes.     

Involvement of endothelial progenitor cells in the formation of plexiform lesions in broiler chickens: possible role of local immune/inflammatory response

Plexiform lesions (PLs), which are often accompanied by perivascular infiltrates of mononuclear cells, represent the hallmark lesions of pulmonary arteries in humans suffering from severe pulmonary arterial hypertension (PAH). Endothelial progenitor cells (EPCs) have been recently implicated in the formation of PLs in human patients. PLs rarely develop in rodent animal models of PAH but can develop spontaneously in broiler chickens. The aim of the present study was to confirm the presence of EPCs in the PLs in broilers. The immune mechanisms involved in EPC dysfunction were also evaluated. Lungs were collected from commercial broilers at 1 to 4 weeks of age. The right/total ventricle ratios indicated normal pulmonary arterial pressures for all sampled birds. Immunohistochemistry was performed to determine the expressions of EPC markers (CD133 and VEGFR-2) and proangiogenic molecule hepatocyte growth factor (HGF) in the lung samples. An EPC/lymphocyte co-culture system was used to investigate the functional changes of EPCs under the challenge of immune cells. PLs with different cellular composition were detected in the lungs of broilers regardless of age, and they were commonly surrounded by moderate to dense perivascular mononuclear cell infiltrates. Immunohistochemical analyses revealed the presence of CD133⁺ and VEGFR-2⁺ cells in PLs. These structures also exhibited a strong expression of HGF. Lymphocyte co-culture enhanced EPC apoptosis and completely blocked HGF-stimulated EPC survival and in vitro tube formation. Taken together, this work provides evidence for the involvement of EPCs in the development of PLs in broilers. It is suggested that the local immune cell infiltrate might serve as a contributor to EPC dysfunction by inducing EPC death and limiting their response to angiogenic stimuli. Broiler chickens may be valuable for investigating reversibility of plexogenic arteriopathy using genemodified inflammation-resistant EPCs.     

An international collaborative investigation of beginning seventh grade students' understandings of scientific inquiry: Establishing a baseline

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65–83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country.
