    Vietnam has an age-old history of education, and Vietnamese people have high respect for learning. However, early childhood education (ECE) in Vietnam has been the main concern only since 1945. This paper describes the process of establishment and development of ECE in Vietnam. Before and during the French colonial period in Vietnam, early childhood education was not considered a social task, and therefore, there was no formal educational system and curriculum for preschool children at this time. After 1945, with the great transformation of history, Vietnamese education has changed dramatically so that from 1945 to 1975 it was a period of political, social and educational separation. The historical events affect the education system and early childhood education in Vietnam. Consequently, the history of ECE in Vietnam is separated into two main phases, before and after 1975. Through the ups and downs of history, Vietnam has successfully built the ECE system. Over seven decades of development, ECE in Vietnam has made remarkable changes. The change comes not only from the expansion of the number of educational institutions, but also from the curriculum and pedagogy that are considered as the most important changes. Gradually escaping the influence of teacher-centered pedagogy, Vietnamese ECE is aiming to build a child-centered education, thereby helping learners to reach their full potential

    Rural Roads: Multi-Tier Monitoring of Infrastructure: Top Down and Bottom Up

    The focus of this paper is on the last set of these questions -- that of the capacity and the practice of decentralized infrastructure monitoring. The experience and practice of low, middle and high income countries alike is considered. The paper is organized as follows: the next section, Section 2, defines how infrastructure is defined for purposes here, and then proceeds to discuss where the monitoring of infrastructure fits into the broader activity of decentralized infrastructure management. Section 3 then lays out some of the “pre-conditions” for effective decentralized monitoring of infrastructure, leading to the conclusion that for many developing countries these pre-conditions are not satisfied and, thus, why in order to make useful statements about decentralized monitoring of infrastructure one turns to specific case studies for lessons learned from current practice. Accordingly, Section 4 focuses on a mix of illustrative country practices on governmental monitoring of infrastructure that serve to reinforce the conventional view that though there are core lessons common to all intergovernmental societies, there is no single “best” approach since each country faces different starting and end points to which they aspire. Section 5 reviews selected non-governmental and civil society role in what the paper labels as decentralized “bottom up” monitoring. Concluding comments are provided in Section 6

    Praise as Classroom Communicative Reinforcing Device: Perceptions of Vietnamese University Students

    One of the biggest challenges for teachers is to foster a positive learning environment in which students become motivated and engaged in classroom activities. Growing concerns have been shown about how evaluative praise functioned as a good reinforcer for students' achievement and desirable behaviour affects students' motivation to learn, depending on teachers' messages communicated with students. This study examined the impacts of different types of teacher praise upon university students' perceptions. Case study was employed to collect the data through observations and semi-structured interviews. The results highlighted that students perceived differently towards kinds of praise that they earned. They tended to respond to specific, verbal praise in a more positive way because of its explicit recognition and precise information about their contributions, hence it could make better their self-concept as well as help them keep motivated. Also, high-achievers sought for ability praise whereas low-achievers desired to draw effort praise from teachers. Educators would benefit these findings for the pedagogical purposes

    Population structure, genetic connectivity, and signatures of local adaptation of the giant black tiger shrimp (Penaeus monodon) throughout the indo-pacific region

    The giant black tiger shrimp (Penaeus monodon) is native to the Indo-Pacific and is the second most farmed penaeid shrimp species globally. Understanding genetic structure, connectivity, and local adaptation among Indo-Pacific black tiger shrimp populations is important for informing sustainable fisheries management and aquaculture breeding programs. Population genetic and outlier detection analyses were undertaken using 10,593 genome-wide single nucleotide polymorphisms (SNPs) from 16 geographically disparate Indo-Pacific P. monodon populations. Levels of genetic diversity were highest for Southeast Asian populations and were lowest for Western Indian Ocean (WIO) populations. Both neutral (n = 9,930) and outlier (n = 663) loci datasets revealed a pattern of strong genetic structure of P. monodon corresponding with broad geographical regions and clear genetic breaks among samples within regions. Neutral loci revealed seven genetic clusters and the separation of Fiji and WIO clusters from all other clusters, whereas outlier loci revealed six genetic clusters and high genetic differentiation among populations. The neutral loci dataset estimated five migration events that indicated migration to Southeast Asia from the WIO, with partial connectivity to populations in both oceans. We also identified 26 putatively adaptive SNPs that exhibited significant Pearson correlation (P < 0.05) between minor allele frequency and maximum or minimum sea surface temperature. Matched transcriptome contig annotations suggest putatively adaptive SNPs involvement in cellular and metabolic processes, pigmentation, immune response, and currently unknown functions. This study provides novel genome-level insights that have direct implications for P. monodon aquaculture and fishery management practices

    Fine-scale population structure and evidence for local adaptation in Australian giant black tiger shrimp (Penaeus monodon) using SNP analysis

    Background: Restrictions to gene flow, genetic drift, and divergent selection associated with different environments are significant drivers of genetic differentiation. The black tiger shrimp (Penaeus monodon), is widely distributed throughout the Indian and Pacific Oceans including along the western, northern and eastern coastline of Australia, where it is an important aquaculture and fishery species. Understanding the genetic structure and the influence of environmental factors leading to adaptive differences among populations of this species is important for farm genetic improvement programs and sustainable fisheries management. Results: Based on 278 individuals obtained from seven geographically disparate Australian locations, 10,624 high-quality SNP loci were used to characterize genetic diversity, population structure, genetic connectivity, and adaptive divergence. Significant population structure and differentiation were revealed among wild populations (average FST = 0.001–0.107; p <  0.05). Eighty-nine putatively outlier SNPs were identified to be potentially associated with environmental variables by using both population differentiation (BayeScan and PCAdapt) and environmental association (redundancy analysis and latent factor mixed model) analysis methods. Clear population structure with similar spatial patterns were observed in both neutral and outlier markers with three genetically distinct groups identified (north Queensland, Northern Territory, and Western Australia). Redundancy, partial redundancy, and multiple regression on distance matrices analyses revealed that both geographical distance and environmental factors interact to generate the structure observed across Australian P. monodon populations. Conclusion: This study provides new insights on genetic population structure of Australian P. monodon in the face of environmental changes, which can be used to advance sustainable fisheries management and aquaculture breeding programs
