Abstract:
This is a conceptual paper on low achievers and vocabulary learning strategies. The paper focuses onwhat vocabulary is, its importance, types of vocabulary learning strategies, low achievers and theirvocabulary learning, the importance of explicit teaching of vocabulary learning strategies to lowachievers and also studies done on them. Low achievers need to be made aware of the existence of thesestrategies and employ them in their learning. This is because they have less motivation to learn Englishas they are weak in this subject. Learners should also be taught on these strategies explicitly so that theyare able to be autonomous in their learning. The knowledge on the strategies that they get will be helpfullater in the work place as they will encounter various types of vocabulary that are related to their job.The paper ends with the conclusion and recommendations on ways to help low achievers to enhance theirvocabulary knowledge. Keywords: language learning strategies, vocabulary learning strategies, low achievers, explicit vocabulary teaching

Abstract:
Most junior high school students get some difficulties in recount text writing. The purpose of this research is to explain the kind of corrective feedback that is more effective for high achievers’, for low achievers, and for mixed groups of high and low achievers in enhancing their ability in recount text writing and explain the interaction between corrective feedback, students’ prior achievement, and ability in recount text writing. The samples are eighth-graders of SMP Agus Salim. The experiment group receives direct corrective feedback while the control group receives indirect corrective feedback. And from both groups, the researcher divides again into two groups of high and low achievers. Finally, direct feedback is more effective for mixed groups of high and low achievers. The sum of means score of the experimental group is 63.75. While the total means score of the control group is 63.50. The mean score of the high achievers that received direct corrective feedback is 62.00, while the low achievers were 65.5. And from the control group, the high achiever group mean is 66.00 while the low achiever group means is 61.00. So direct corrective feedback is better used for low achievers.

Abstract:
Play therapy in a school setting was studied to determine its therapeutic effectiveness on students' reading achievement, self-concept, and locus of control. The sample consisted of 24 students in two first grade classes who had been retained because of low achievement in reading. Instruments used in the study were the Gates MacGinite Reading Test, the Piers-Harris Children's Self-Concept Scale, and the Intellectual Achievement Responsibility Questionnaire. Analysis of covariance, used to test the significance of the difference between the adjusted post-test means of the experimental and control groups, showed that participants in play therapy scored significantly higher in self-concept than did those who were not exposed to treatment. No statistically significant differences were found between the two groups in reading achievement or locus of control. Since research has shown that low achievers in reading tend to have low self-concepts, it seems reasonable to assume that improved self-concept would be related to improved reading scores. The nature of such a possible relationship needs further study. Recommendations were made for integrating affective components into academic remediation programs, and suggestions for further research were made.

Abstract:
The aim of this study was to find out what attitudes students of English at Upper Secondary School have to the classroom teaching, in relation to the grade they are expecting in the current course. Furthermore, the question was whether the high achievers, also referred to as “top grade” students, felt more motivated than the low achievers, also referred to as “lower grade” students. In order to answer the research questions, the phenomenon motivation first had to be examined by studying findings by different scholars. The study was carried out with a questionnaire as the instrument. It was filled in by 86 students at a freeform Upper Secondary school in the middle of Sweden. The questionnaire asked questions about the difficulty of the course, the students’ motivation for the tasks given and also what impact the teacher had on the students’ progress. 19 high achievers were identified in the study, and 8 low achievers. The results showed that the high achievers show more positive results on attitudes and motivation in all areas. They expect higher grades and they express an interest in more areas than the low achievers do. On the other hand, no difference was found between the groups when it comes to the way they rate their interest in learning English. Similarly, students in both groups understand the need for English in their future life and careers. The results suggest that both groups are driven by instrumental motivation. The results of the present study correspond to those found in earlier studies by different scholars.

Abstract:
This is a report of an investigation of children’s beliefs about the nature of mathematics, the nature of learning and helping factors for learning mathematics. The study aimed to investigate whether beliefs held by eight learners of eight to nine years of age could be articulated and portrayed. It aimed also to develop procedures to facilitate this process, to portray children’s beliefs from their responses to the research procedures, to provide insights into possible complexities and subtleties of young learners’ beliefs, to reflect upon the significance for the mathematics classroom of the insights gained, and to reflect upon the value of the procedures developed for the study. The research took the form of individual case studies of four girls and four boys of eight to nine years of age from two schools in suburban Melbourne. Four children were teacher-perceived low achievers in mathematics and four were teacher-perceived high achievers in mathematics. The children were each interviewed on ten occasions over a five-month period using thirty semi-structured, creative interviewing procedures that were developed or adapted for the study that included drawing, writing, discussing scenarios presented through photographs, video snippets and other children’s drawings, ordering of descriptors, and responding to questionnaires presented verbally. The interview data consisted of transcripts and artefacts. Some class administered tasks, lesson observations and interviews with the mathematics teachers provided background information. Analysis of interview responses was undertaken through a criss-cross examination in which themes were drawn from each child’s data. Responses were not judged for correctness or for a match to any predetermined categories and the researcher sought to take a stance of neutrality to the phenomena under study. The research suggests that teachers and others involved in the education of young learners of mathematics should know that: it is possible to gain insights into children’s beliefs about maths (the term used most commonly by the children), learning, and helping factors for learning maths; to gain insights into young children’s beliefs, it is important to have dialogue with the children to avoid making assumptions about their interpretations or meanings; the creative interviewing procedures developed for the present research are helpful as they can stimulate reflection and prompt conversation; young children’s beliefs can be complex, subtle, broad and deep; young children’s beliefs are individually constructed and differ from child to child; children may not see mathematics concepts in the same ways as their teachers and other adults; beliefs are sufficiently diverse and significant to affect the way children see the mathematics learning situation; although the beliefs of children of eight to nine years of age may, on the surface, appear simplistic and naïve, they are not necessarily so. Young learners are able to reflect on their own and others’ experiences and often construct complex beliefs. There is a lot happening in the minds of these children. The research suggests also that it is important that educators do not to make assumptions about: what children see as maths (or mathematics); what children see as learning; and what children see as helping factors for learning maths. A key factor facilitating children’s reflection and expression was the range of visual, verbal, and text-based creative interviewing strategies developed for the present study. The individual procedures provided suitable prompts to allow young children to articulate or represent their beliefs. The semi-structured procedures, through which ideas were explored on multiple occasions, followed by theme-based, criss-cross analysis of interview transcripts and artefacts, resulted in rich and trustworthy portrayals of beliefs, increasing the validity of the findings. The research provides the education community with insights into young children’s beliefs that are unlikely to emerge within the day to day activity of the classroom and, through the availability of the research procedures, facilitates further gaining of insights into beliefs either by classroom teachers or other researchers.

Abstract:
AbstractAustralia’s education system reflects its history of federalism. State and territory governments are responsible for administering education within their jurisdiction and across the sector comprising government (public), Catholic systemic and other independent schooling systems. They collaborate on education policy with the federal government. Over the past two decades the federal government has taken a greater role in funding across the education sector, and as a result of this involvement and the priorities of federal governments of the day, Australia now has one of the highest rates of non-government schooling in the OECD. Funding equity across the sectors has become a prominent issue. Concerns have been compounded by evidence of declining student performance since Australia’s initial participation in PISA in 2000, and the increasing gap between our high achievers and low achievers. This chapter explores Australia’s PISA 2018 results and what they reveal about the impact of socioeconomic level on student achievement. It also considers the role of school funding and the need to direct support to those schools that are attempting to educate the greater proportion of an increasingly diverse student population including students facing multiple layers of disadvantage.

Abstract:
Families, schools and stakeholders long for developing good readers (Ponitz & Rimm-Kaufman, 2011) and would do all it takes to save young children from becoming illiterate or low achievers (Anthony & Farncis, 2005; Share & Stanovich, 1995; Snowling, 1998). Since the landmark study of Moats (1994), a flow of research has targeted teacher education advocating for teachers being competent in PA (Carlisle, Kelcey, Rowan, & Phelps, 2011; Kennedy, 2013; Washburn et al., 2017). EFL teachers’ proficiency seems to contribute to the reading difficulties that early graders encounter. This paper investigates the knowledge, beliefs, practices and awareness in phonological awareness (PA) of twohundred and ten ramdonly selected EFL in-service teachers and then examines the impact of teachers’ experiences, qualifications, and gender on shaping teachers’ instruction. The researchers used a four-section survey to collect teachers’ demographic information, perceived and actual knowledge of phonological awareness and classroom practices related to PA, phonics, and syllabication. The results reported teachers as moderate level in the beliefs, practice and awareness of PA. In terms of teachers’ knowledge in PA, however, results showed teachers lacking the basics in teaching reading. This study adds to the body of literature and sheds light on the status quo of EFL in-service teachers’ competency and brings to the attention of every stakeholder the critical role EFL teachers play in helping EFL children become readers. Although the results point towards teachers as possible cause behind children’s low-literacy level, this study raises important questions for further investigations, and implications for EFL teacher education and preparation are highlighted.

Abstract:
We present Any-Precision Deep Neural Networks (Any- Precision DNNs), which are trained with a new method that empowers learned DNNs to be flexible in any numerical precision during inference. The same model in runtime can be flexibly and directly set to different bit-width, by trun- cating the least significant bits, to support dynamic speed and accuracy trade-off. When all layers are set to low- bits, we show that the model achieved accuracy compara- ble to dedicated models trained at the same precision. This nice property facilitates flexible deployment of deep learn- ing models in real-world applications, where in practice trade-offs between model accuracy and runtime efficiency are often sought. Previous literature presents solutions to train models at each individual fixed efficiency/accuracy trade-off point. But how to produce a model flexible in runtime precision is largely unexplored. When the demand of efficiency/accuracy trade-off varies from time to time or even dynamically changes in runtime, it is infeasible to re-train models accordingly, and the storage budget may forbid keeping multiple models. Our proposed framework achieves this flexibility without performance degradation. More importantly, we demonstrate that this achievement is agnostic to model architectures. We experimentally validated our method with different deep network backbones (AlexNet-small, Resnet-20, Resnet-50) on different datasets (SVHN, Cifar-10, ImageNet) and observed consistent results.

Abstract:
Soils containing inorganic compounds are frequently encountered by transportation agencies during construction within the right-of-way, and they pose a threat to human health and the environment. As a result, construction activities may experience project delays and increased costs associated with management of inorganic compounds containing soils required to meet environmental regulations. Recalcitrance of metal-contaminated soils toward conventional treatment technologies is exacerbated in clay or organic content-rich fine-grained soils with low permeability and high sorption capacity because of increased treatment complexity, cost, and duration. The objective of this study was to develop an accelerated in situ electrochemical treatment approach to extract inorganic compounds from fine-grained soils, with the treatment time comparable to excavation and off-site disposal. Three reactor experiments were conducted on samples collected from two borehole locations from a field site in Illinois that contained arsenic (As)(~7.4 mg/kg) and manganese (Mn)(~700 mg/kg). A combination of hydrogen peroxide (H2O2) and/or citrate buffer solution was used to treat the soils. A low-intensity electrical field was applied to soil samples using a bench-scale reactor that resembles field-scale in situ electrochemical systems. For the treatment using 10% H2O2 and citrate buffer solution, average removal of 23% and 8% were achieved for Mn and As, respectively. With 4% H2O2 and citrate buffer, 39% and 24% removal were achieved for Mn and As; while using only citrate buffer as the electrolyte, 49% and 9% removal were achieved for Mn and As, respectively. All chemical regimes adopted in this study reduced the inorganic compound concentrations to below the maximum allowable concentration for Illinois as specified by the Illinois Environmental Protection Agency. The results from this work indicate that electrochemical systems that leverage low concentrations of hydrogen peroxide and citrate buffer can be effective for remediating soils containing manganese and arsenic.

Abstract:
This report evaluates scope 3 emissions along the copper and iron ore value chains and the opportunities that Latin America and the Caribbean (LAC) has to become a low carbon metals and solutions hub. The report presents four carbon emission scenarios that represent different sets of decisions for policy-makers and investors. Two scenarios fall short of aligning with Paris targets: (1) the business as usual (BaU) scenario with no further abatement action; and (2) a BaU scenario with the current level of emission reduction potential from players in the value chain (BaU Possible). The other two scenarios deliver the required carbon reductions to be compliant with the Paris Agreement by 2060, but through different strategies: (3) the BaU Paris scenario. where alignment with Paris targets is achieved by keeping BaU volumes and reducing carbon intensity per tonne of metal; and (4) the Decoupled scenario, where carbon intensity reductions are relaxed and compensated by a reduction in primary supply to align the value chain emissions to a Paris trajectory. All scenarios require LACs leaders to consider investments in low-carbon technology in different degrees. The report argues that, given its competitive position in the cost curve for copper and iron ore and an abundance of enabling factors for low carbon strategies, the region could become a key source of low carbon metals and solutions as long as it is proactive in adopting all the necessary measures from public sector and industry perspectives. Finally, the report concludes that myriad opportunities exist for LAC, including new business models, technologies and products, and that these could yield a greater economic and social contribution to the region than the BaU trajectories.

Abstract:
To deliver infrastructure that sustain our communities, economy, and environment, we must innovate, modernize, and even revolutionize our approach to infrastructure development. Change takes courage, but as one starts down the path of innovation, what was once novel becomes more familiar, more established. The U.S. Army Corps of Engineers (USACE) is walking this path with our partners through the Engineering With Nature (EWN) Initiative, integrating human engineering with natural systems. The International Guidelines on Natural and Nature-Based Features for Flood Risk Management are the next step toward revolutionary infrastructure development—a set of real-world guidelines to help familiarize us with what was once novel. USACE and collaborators around the world have been building, learning, and documenting the best practices for constructing Natural and Nature-Based Features (NNBF) for decades. The consolidation of these lessons into a single guidance document gives decision-makers and practitioners a much-needed resource to pursue, consider, and apply NNBF for flood risk management while expanding value through infrastructure. Relationships and partnerships are vital ingredients for innovation and progress. The NNBF Guidelines was achieved because of the strong relationships in the nature-based engineering community. The magnitude and diversity of contributors to the NNBF Guidelines have resulted in a robust resource that provides value beyond a single agency, sector, or nation. Similarly, the work of incorporating NNBF into projects will require us to strengthen our relationships across organizations, mandates, and missions to achieve resilient communities. I hope you are inspired by the collaborative achievement of the NNBF Guidelines and will draw from this resource to develop innovative solutions to current and future flood risk management challenges. There is a lot we can achieve together along the path of revolutionary infrastructure development.

Abstract:
The current COVID-19 epidemic is both a health and societal issue; therefore, groups historically excluded and marginalised in terms of healthcare will suffer if COVID-19 vaccines, tests, and treatments are to be delivered equitably. This rapid review is exploring the social and cultural challenges related to the roll-out, distribution, and access of COVID-19 vaccines, tests, and treatments. It highlights how these challenges impact certain marginalised groups. Case studies are taken from sub-Saharan Africa (the Democratic Republic of Congo, South Africa), with some focus on South East Asia (Indonesia, India) as they have different at-risk groups. Lessons on this issue can be learned from previous pandemics and vaccine roll-out in low- and mid-income countries (LMICs). Key points to highlight include successful COVID-19 vaccine roll-out will only be achieved by ensuring effective community engagement, building local vaccine acceptability and confidence, and overcoming cultural, socio-economic, and political barriers that lead to mistrust and hinder uptake of vaccines. However, the literature notes that a lot of lessons learned about roll-out involve communication - including that the government should under-promise what it can do and then over-deliver. Any campaign must aim to create trust, and involve local communities in planning processes.

Abstract:
This Insight Note contributes to the growing body of knowledge on teaching practices that foster student learning and achievement by analysing in-depth qualitative data from classroom observations and teacher interviews. Much of the research on teachers and teaching in development literature focuses on observable and quantified factors, including qualifications and training. But simply being qualified (with a university degree in education or subject areas), or trained in certain ways (e.g., coaching versus in-service) explains very little of the variation in learning outcomes (Kane and Staiger, 2008; Wößmann, 2003; Das and Bau, 2020). Teaching is a complex set of practices that draw on teachers’ beliefs about learning, their prior experiences, their content and pedagogical knowledge and repertoire, and their commitment and personality. Recent research in the educational development literature has turned to examining teaching practices, including content knowledge, pedagogical practices, and teacher-student interactions, primarily through quantitative data from knowledge tests and classroom observations of practices (see Bruns, De Gregorio and Taut, 2016; Filmer, Molina and Wane, 2020; Glewwe et al, in progress). Other studies, such as TIMSS, the OECD and a few World Bank studies have used classroom videos to further explain high inference factors of teachers’ (Gallimore and Hiebert, 2000; Tomáš and Seidel, 2013). In this Note, we ask the question: What are the teaching practices that support and foster high levels of learning? Vietnam is a useful case to examine because student learning outcomes based on international tests are high, and most students pass the basic learning levels (Dang, Glewwe, Lee and Vu, 2020). But considerable variation exists between learning outcomes, particularly at the secondary level, where high achieving students will continue to upper-secondary and lower achieving students will drop out at Grade 9 (Dang and Glewwe, 2018). So what differentiates teaching for those who achieve these high learning outcomes and those who don’t? Some characteristics of teachers, such as qualifications and professional commitment, do not vary greatly because most Vietnamese teachers meet the national standards in terms of qualifications (have a college degree) and have a high level of professionalism (Glewwe et al., in progress). Other factors that influence teaching, such as using lesson plans and teaching the national curriculum, are also highly regulated. Therefore, to explain how teaching might affect student learning outcomes, it is important to examine more closely teachers’ practices in the classroom.
