Quantitative PCR (qPCR) TL measurement has been favored as a cost-effective method that can be easily implemented, especially in population studies with limited quantities of source material. However, several recent reports have revealed inconsistencies in telomere length measurements when applying different DNA extraction methods to the same source material. In this study we tested three DNA extraction methods on saliva samples from 48 participants of the National Growth and Health Study (NGHS) collected with DNA Genotek’s Oragene kit. The chosen extraction kits represent three distinct approaches to genomic DNA extraction from lysed cells and we employed two different operators to carry out all assays on the same samples. We measured DNA yield and quality and calculated the between-operator agreement of qPCR TL measurements (intraclass correlation, ICC). Our analyses showed that while both QIAamp and Agencourt DNAdvance had higher agreement between the 2 operators (ICC=0.937, CI [0.891, 0.965] and ICC=0.95, CI [0.911, 0.972] respectively), compared to PrepIT kit (ICC=0.809, CI [0.678, 0.889]), QIAamp extracted DNA samples were notably degraded. Using generalizability theory, we found that the participant-by-extraction-method interaction explained about 10% of total variation in TL, suggesting that TL differences across methods are somewhat participant-specific. Therefore, our results suggest that the among the three DNA extraction methods tested, Agencourt (magnetic bead purification) is the preferred kit, and we also strongly recommend against combining different extraction methods within a study population.","PeriodicalId":92378,"journal":{"name":"International journal of educational methodology","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84563723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The expressions of anger are subjective and sometimes hard to identify. Thus, anger should be measured more objectively, while the expressions need to be examined closely. The purpose of this study is to provide valid confirmation for development of an online instrument to measure the types of anger expression among adolescents. Data were collected from 935 adolescents from nine schools in northern Malaysia and the theoretical literature search. The data were analysed to provide evidence of construct validity in terms of item factor analysis, reliability estimates, and correlation between the types of anger expressions. Findings were used to develop an online Adolescent Anger Instrument. It measures five types of anger expressions, namely, physical, verbal, intrinsic, extrinsic, and passive. The results showed that the instrument is internally consistent with high evidence of construct validity. Exploratory factor analysis, with varimax rotation, suggested the existence of five distinct types of anger as conceptualised. Meanwhile, the correlation between types of anger expressions indicates the strength of the relationship between them. Discussions on the findings are provided, while suggestions for future research are also described.","PeriodicalId":92378,"journal":{"name":"International journal of educational methodology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42287230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study results are summarized as follows. First, EMI courses could enhance international students' content knowledge development effectively. Second, EMI courses could improve international students' English proficiency in terms of reading and vocabulary ability. Third, international students showed high satisfaction with EMI courses and are willing to take EMI courses continuously. However, the interview analysis showed that it was challenging for a few international students to improve their English speaking ability due to limited opportunities to speak English during graduate-level courses. These study results suggest several recommendations to provide practical EMI courses for teaching diverse international students, including English language learners in higher education.","PeriodicalId":92378,"journal":{"name":"International journal of educational methodology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43168525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A mixed research method was used to collect the end-of-semester survey (n=62) and individual interview data (n=4). Guided by the four pillars of flipped learning (FL), study results are followed. First, Korean pre-service teachers believed that flipped learning format provided a flexible learning environment where pre-service teachers (PSTs) learn course materials in their own space. This result indicated that their learning happened without the limits of time and space. Second, pre-service teachers showed that their self-directed learning could be enhanced while watching pre-recorded videos before attending the class. Most PSTs agreed that their self-directed learning could be enhanced after participating in the flipped learning courses. Third, pre-service teachers evaluated that the FL course instructor was a professional educator who conveyed the intentional content effectively. Fourth, pre-service teachers were generally satisfied with the FL courses and were willing to take the FL courses again in the future.","PeriodicalId":92378,"journal":{"name":"International journal of educational methodology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45567938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If disasters are not properly foreseen, they may result in many fatalities. This research aims to examine the growth and pattern of literature on natural disaster education in schools. This analytical strategy combines quantitative and statistical methods to discover trends, assess quality, and track development. A total of 216 documents were chosen from the 403 documents collected. Following 2015, there was a considerable increase in four-year publications. Authors from the United States contributed to 45 papers with 37% citations and ranked first, followed by authors from Japan (31 documents; 15% citations) and Indonesia (31 documents) with rankings citations below the top 10. Most publications were published in the International Journal of Disaster Risk Reduction (12 docs; Q1 Scimago Journal Rank 1.1 (SJR 1.1)). The Journal of Child Psychology and Psychiatry and Allied Disciplines had the most citations (100; Q1 SJR 3.6) and was ranked first in its discipline. The existing core literature on school education on natural disasters demonstrates that this topic is developing rapidly, but with insufficient international research collaboration. Research cooperation in this area must be strengthened to better the global response to natural disaster mitigation, which should begin in schools worldwide. There is a need to widen the scope of study in this field to include natural disaster preparedness education in the school curriculum, assessments, learning media, disaster response education, and instructional designs. Finally, disaster education in schools must be addressed as soon as possible to contribute to disaster preparedness.","PeriodicalId":92378,"journal":{"name":"International journal of educational methodology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42517575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The students' statements are analyzed in order to gain an understanding of their experiences of developing academic literacies in their university studies. They are regularly visiting the university study workshop for help with their exam assignments. The following questions have been formulated to fulfil the aim of the study: (a) what aspects of studies in higher education do the students express as important, favorable, or unfavorable, for their development of academic literacies? and (b) in what way do the students value the study workshops as an educational tool? The analysis reveals three themes: the importance of explicit support structures, the importance of teachers’ feedback, and the importance of using the students’ pedagogical capital. The results also show that the students highly value the study workshop when they reflect upon the one-to-one feedback, but the support seems to be insufficient both in supporting them to be more independent in their studies and in developing academic literacies from a critical and epistemological point of view.","PeriodicalId":92378,"journal":{"name":"International journal of educational methodology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44567258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
