Meeting the Needs of English Language Learners in Mississippi Through Professional Development

The problem addressed in this study is that Native American and Hispanic English language learners (ELLs) in a rural Mississippi school district are not performing at the same level as non-ELLs. The purpose of this qualitative case study was to investigate the perceived causes of ELL failure and low academic performance on district and state assessments and in general education classes. Guided by Vygotsky\u27s theory of development, which supports teachers and students remaining active in the learning process, research questions focused on what instructional practices general education teachers use to provide instruction for Spanish/Choctaw-speaking ELLs. General education teachers\u27 use of professional learning communities (PLCs), instructional and assessment practices, knowledge of ELLs\u27 instructional needs, and perceptions of professional development (PD) were examined. The purposeful sample for surveys included 33 Kindergarten through12 general education teachers who met the criteria of having the experience of providing instruction to ELLs. Teacher participants completed an online anonymous survey through SurveyMonkey. Six English Language Arts (ELA) teachers and 1 administrator participated in face-to-face interviews. The responses were open coded then analyzed using NVivo 11. Seven themes emerged from the data: differentiation is critical for ELL instruction, assessment should drive instruction, ELLs benefit from evidence based instructional strategies, PLCs support general education teachers, PD is inadequate to support ELLs and teacher needs, PD is needed on ELLs background, and administrators\u27 support PLCs for ELLs\u27 instruction. A 5-day PD project was designed and positive social change promoted by providing staff with evidence based ELL instructional support, resulting in improved ELL learning and achievement

Extrapolation suitability index for sustainable vegetable cultivation in Babati district, Tanzania.

Open Access JournalLand suitability assessment matches crop requirements with available resources to promote sustainable production. Scaling out of sustainable agricultural intensification practices to suitable biophysical and socio-economic conditions reduces the risk of failure and increases their adoption rate. This study applies a geospatial framework to identify potentially suitable sites for extrapolating two improved vegetable cultivars grown under integrated management practices (IMP’s) in Babati District of Tanzania. On-farm trial data on the yield and income of two cultivars were used as a reference. Extrapolation was based on the gridded biophysical and socio-economic layers that limit the production of the two improved vegetable cultivars’. The extrapolation suitability index (ESI) showed the areas where cultivation of the two improved vegetable cultivars under IMP’s can be scaled-out with a potentially low risk of failure. We generate maps of the most important limiting factor for each cultivar in every pixel to guide the spatial targeting of appropriate remedial measures. Application of these maps will promote evidence-based scaling out of improved vegetable technologies by the extension and development agencies

Safety, Humoral and Cell Mediated Immune Responses to Two Formulations of an Inactivated, Split-Virion Influenza A/H5N1 Vaccine in Children

BACKGROUND:Highly pathogenic influenza A/H5N1 has caused outbreaks in wild birds and poultry in Asia, Africa and Europe. It has also infected people, especially children, causing severe illness and death. Although the virus shows limited ability to transmit between humans, A/H5N1 represents a potential source of the next influenza pandemic. This study assesses the safety and immunogenicity of aluminium hydroxide adjuvanted (Al) and non adjuvanted influenza A/Vietnam/1194/2004 NIBRG-14 (H5N1) vaccine in children. METHODS AND FINDINGS:In a Phase II, open, randomised, multicentre trial 180 children aged 6 months to 17 years received two injections, 21 days apart, of vaccine containing either: 30 microg haemagglutinin (HA) with adjuvant (30 microg+Al) or 7.5 microg HA without adjuvant. An additional 60 children aged 6-35 months received two "half dose" injections (ie 15 microg+Al or 3.8 microg). Safety was followed for 21 days after vaccination. Antibody responses were assessed 21 days after each injection and cellular immune responses were explored. Vaccination appeared well tolerated in all age groups. The 30 microg+Al formulation was more immunogenic than 7.5 microg in all age groups: in these two groups 79% and 46% had haemagglutinination inhibition antibody titres > or =32 (1/dil). Among 6-35 month-olds, the full doses were more immunogenic than their half dose equivalents. Vaccination induced a predominantly Th2 response against H5 HA. CONCLUSIONS:This influenza A(H5N1) vaccine was well tolerated and immunogenic in children and infants, with Al adjuvant providing a clear immunogenic advantage. These results demonstrate that an H5N1 Al-adjuvanted vaccine, previously shown to be immunogenic and safe in adults, can also be used in children, the group most at risk for pandemic influenza
