This study aims to examine the effects of flipped learning on L2 students' overall academic achievements through meta-analysis. Forty studies (e.g., journal articles, M.A/Ph.D. theses and conference papers) on 'flipped classroom', 'flipped learning' and 'academic achievement' were included in this meta-analysis study. The data was analyzed by using Comprehensive Meta-Analysis Software. The random effects model was used in analyzing the overall effect size and the heterogeneity of the studies included in this meta-analysis. The results revealed that flipped learning has statistically significant effect on L2 learners' academic achievements (g=1.303) compared to traditional learning approaches. This result does not differ according to publication type, educational level and four basic language skills and sub-skills, but it differs according to sample size of the selected studies.

This paper provides an account of the topological and its description of contemporary culture and use as a research methodology, a topological lens, generally, and in education research specifically. Some commentary is proffered on the relationships between the topological and the topographical, between relations and locations. A critical account is then provided on each of the papers in the special issue on the topological in education research and the specific contributions of each. The editors of the special issue make the important point that the topological is a spatio-temporal phenomenon, not just a spatial one. The topological does not exist in time and space, but rather constructs both and they change in a conjoint manner. As such, a topological lens rejects a construction of space as static and of time (and the temporal) as simply linear and chronological. The topological has been facilitated and articulated by and through practices of commensuration, datafication and digitalisation, flows and scapes, global connectivities and new relations, mobilities of various kinds and multiple networks. The paper argues that much greater emphasis has been given to the spatial in topological research; that is, there has been some neglect of the temporal in the spatio-temporal character of topologies.

The study discussed in this paper is a systematic literature review related to the role of dual language programme (DLP) in mathematics education which has been published within the last 5 years. This study was conducted to identify the distribution of DLP studies in terms of year of publication, the study context covered in previous studies, the context of study areas used, focus and trends of past studies, research methods used in previous studies and the role of language in school mathematics education. This review study followed the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) to analyze articles from Scopus and Web of Science. The findings of the study indicate that research trends in the implementation of the DLP on mathematics education for secondary school students showed an increase from 2017 to 2019. Most DLP-related articles are widely developed in the United States and Germany. The findings indicate that previous studies are more interested in studying the implementation of DLP in rural areas. Past studies have also preferred to use the design of either a qualitative study or a quantitative study to be implemented. Questionnaires, tests and interviews are among the research instruments that are often used for a study.

Background: The Double OT (DOT) assessment is occupation-based and dynamic, designed with a clientcentered format requiring skill demonstration. It was developed to support youth transitioning into the workplace. This research intended to analyze initial validity and users' experience. Method: This study includes qualitative and quantitative analyses of data collected from surveys from 169 client participants (APs) and 30 recipient participants (ARRs) from eight sites in the USA and Europe. AP were 14 to 25 years of age and engaged in residential, educational, and vocational settings. The ARRs comprised partners who had received DOT assessment summaries about APs with whom they worked. Results: The APs showed high engagement and learning; average ratings for each item fell between 4.24-4.54 on a 5-point Likert scale. The ARRs agreed on the validity and usability of the DOT; average ratings for each item fell between 3.75 and 4.53 on a 5-point Likert scale. Qualitative themes indicated that the DOT is: "fun and engaging," "vocationally informative and applicable," and that there is an absence of commonly used assessments informing vocational transitions. Conclusion: The results support initial validity of the DOT. Users find it to be highly engaging, with good usability, and indicate that it facilitates participant learning. [ABSTRACT FROM AUTHOR]

Background: As single-cell sequencing technology has been gradually introduced, it is essential to characterize global collaboration networks and map development trends over the past 20 years.Objective: The aim of this paper was to illustrate collaboration in the field of single-cell sequencing methods and explore key topics and future directions.Methods: Bibliometric analyses were conducted with CiteSpace and VOSviewer software on publications prior to November 2019 from the Web of Science Core Collection about single-cell sequencing methods.Results: Ultimately, we identified 2489 records, which were published in 495 journals by 14,202 authors from 1970 institutes in 61 countries. There was a noticeable increase in publications in 2014. The United States and high-income countries in Europe contributed to most of the records included. Harvard University, Stanford University, Karolinska Institutes, Peking University, and the University of Washington were the biggest nodes in every cluster of the collaboration network, and SA Teichmann, JC Marioni, A Regev, and FC Tang were the top-producing authors. Keywords co-occurrence analysis suggested applications in immunology as a developing research trend.Conclusions: We concluded that the global collaboration network was unformed and that high-income countries contributed more to the rapidly growth of publications of single-cell sequencing technology. Furthermore, the application in immunology might be the next research hotspot and developmental direction. [ABSTRACT FROM AUTHOR]
