THE INFLUENCE OF EARLY LITERACY CHARACTERISTICS AND SES ON THE LITERACY ACHIEVEMENT OF STUDENTS WHO SPEAK NON-DOMINANT LANGUAGES IN INDONESIA

Across the world, children from non-dominant language speaking families are not performing as well as their peers who speak a dominant language when they enter school. The current study examines the case of Indonesia, investigating the influence of language background status, early literacy characteristics, and socioeconomic status on literacy achievement in Indonesia. Drawing from the PIRLS 2011 dataset (N = 2,725), findings reveal that there is a significant association between each variable and literacy achievement, and that socioeconomic status explains literacy achievement most strongly among 4th grade students in Indonesia. Implications are discussed.DOI:doi.org/10.24071/ijiet.2019.03021

Realizing the Sustainability of Portfolio Assessment in Second-Language Writing

Portfolio assessment, as an alternative writing assessment approach, has received growing attention in the past few decades. Although the benefits of portfolio assessment are well validated, there is a dearth of empirical research on how portfolio assessment can be sustained over time and the support teachers need to sustain portfolio assessment practice in their teaching contexts. To fill this significant void, the present study examines the influences that contribute to the sustainability of portfolio assessment in second-language writing. Drawing on data from interviews with the principal, English department chair and four English teachers from one elementary school in Hong Kong, as well as classroom observation and teachers’ team meeting observation, the study revealed that administrators’ role in dispersing decision-making authority to teachers, exploiting learning opportunities and providing a stimulating environment for teachers, and the sharing of common vision and goals, as well as collective flows of learning among team members, are the cornerstone of transformation and sustainability for the practice of portfolio assessment. The paper concludes with practical implications on how the innovative attempts in portfolio assessment can be sustained over time

Principal agency 50 years after the Lau decision: Building and sustaining bilingual education programs for Asian languages

This study examined how three champion principals of Asian language dual language bilingual education (DLBE) programs—Cantonese, Korean, and Mandarin—in California have navigated the oscillating language-in-education policies after the Lau decision. We explored principals\u27 various roles through a lens of agency in a social justice leadership framework, specifically considering the opportunities and challenges for agentive leadership from three different phases: foregrounding and engaging, planning and implementing, and evaluating and sustaining. Findings demonstrate that the success of DLBE programs goes beyond the overarching language policies that supposedly enable bilingual education; rather it hinges on the bottom-up commitment, collaboration and resilience of principals, teachers, and parent communities. The blanket policies at the state level often overlooked Asian languages and the unique needs of Asian teachers and communities in DLBE schools, limiting principal agency. Within these confines, principals consistently engaged in advocacy work, such as in teacher recruitment, hiring and work distribution, and curriculum design and assessment, contributing to the growth and sustainability of their programs. By elevating these champions and their experiences and perspectives, this study reflects upon the politicized path to bilingual education 50 years after the Lau case and contributes valuable insights to inform future implementational research, practice, and policy, ensuring the continued flourishing of Asian language bilingual education for the growing constituency of Asian-identifying students

Promoting emergent literacy in preschool through extended discourse: Covert translanguaging in a Mandarin immersion environment

Rich oral language practices, including the opportunity and ability to participate in cognitively and linguistically challenging extended discourse, are foundational to early literacy development. To meet children’s needs in their first exposure to the languages of schooling, educators may engage students in extended discourse multilingually. The current study focuses on student-centered translanguaging conversations to examine strategies that preschool teachers employ to support young children’s emerging bilingual and biliteracy development in a Mandarin immersion preschool serving primarily nonheritage learners of Mandarin in the United States. Findings indicate that, despite the school’s Mandarin-only policy, teachers engaged in covert translanguaging practices to extend and deepen discourse. Specifically, teachers used 13 discourse strategies across two critical areas of schooling: translanguaging for (1) socializing students not just into the Mandarin language but into the norms of schooling; and (2) focusing not just on Mandarin language but also on content area learning. The study concludes with implications for schools and teachers

FluShuffle and FluResort: new algorithms to identify reassorted strains of the influenza virus by mass spectrometry

Background: Influenza is one of the oldest and deadliest infectious diseases known to man. Reassorted strains of the virus pose the greatest risk to both human and animal health and have been associated with all pandemics of the past century, with the possible exception of the 1918 pandemic, resulting in tens of millions of deaths. We have developed and tested new computer algorithms, FluShuffle and FluResort, which enable reassorted viruses to be identified by the most rapid and direct means possible. These algorithms enable reassorted influenza, and other, viruses to be rapidly identified to allow prevention strategies and treatments to be more efficiently implemented.Results: The FluShuffle and FluResort algorithms were tested with both experimental and simulated mass spectra of whole virus digests. FluShuffle considers different combinations of viral protein identities that match the mass spectral data using a Gibbs sampling algorithm employing a mixed protein Markov chain Monte Carlo (MCMC) method. FluResort utilizes those identities to calculate the weighted distance of each across two or more different phylogenetic trees constructed through viral protein sequence alignments. Each weighted mean distance value is normalized by conversion to a Z-score to establish a reassorted strain.Conclusions: The new FluShuffle and FluResort algorithms can correctly identify the origins of influenza viral proteins and the number of reassortment events required to produce the strains from the high resolution mass spectral data of whole virus proteolytic digestions. This has been demonstrated in the case of constructed vaccine strains as well as common human seasonal strains of the virus. The algorithms significantly improve the capability of the proteotyping approach to identify reassorted viruses that pose the greatest pandemic risk. © 2012 Lun et al.; licensee BioMed Central Ltd.Link_to_subscribed_fulltex
