Predictors of English Medium Instruction academic success in Vietnamese Higher Education

Abstract Recent research has investigated predictors of English Medium Instruction (EMI) academic success in Higher Education in various contexts; however, mixed findings have been reported, and empirical research in emerging contexts like Vietnam is relatively scarce. In addition, little is known about the associations between tertiary EMI outcome, gender, and high school performance. To fill these research gaps, the present study was conducted to explore the roles of gender, high school grades, English language proficiency and vocabulary knowledge (both receptive and productive knowledge) in Vietnamese tertiary EMI academic achievement. To this end, 78 Vietnamese undergraduates majoring in business studies participated in the study. The participants took the Vocabulary Levels Test (Schmitt et al. 2001) and Productive Vocabulary Levels Test (Laufer and Nation 1999) to measure their receptive and productive vocabulary knowledge. Their English language proficiency test scores, EMI course grades, and high school grade point average (GPA) were also collected for data analysis. Simple linear regression analyses revealed that high school GPA, English language proficiency together with both receptive and productive vocabulary knowledge significantly predicted EMI academic outcome while gender did not. The results are discussed with implications for EMI in Higher Education.

Values in Indonesian History Textbook

The Indonesian history textbook, the handbook for teachers and students learning history in high school, is compiled by the Ministry of Education and Culture team as teaching material for students. The contents of the published history textbooks have been revised several times to improve the material's content. However, things could still be improved in the material's content or terms of data presentation. Mistakes in history textbooks will have a negative impact on students and their ways of thinking about national history and others. This scientific work aims to objectively analyze and criticize the content of history textbooks for High School Grade X and analyze historical values in the context of history textbook material as history lessons for students. The method used in this scientific work uses qualitative research methods. The data collection technique used a literature review collected in the form of Grade X Indonesian history textbooks and other relevant literature studies. The data analysis technique uses descriptive qualitative by first doing data reduction and concluding. The results of this study show that criticism of Grade X Indonesian history textbooks, which were published in revisions in 2016, still needs to improve, especially in the material and presentation of incorrect historical data. The presentation of historical data in the form of photos of Sriwijaya heritage inscriptions that are irrelevant to the explanation is very dangerous for students' understanding. The presentation of historical values in history textbooks is not visible, so the material presented appears to be only chronological. It is necessary to add subtitles related to historical values in the textbook to achieve the purpose of studying history.

The Effectiveness of Online Group Guidance in Reducing Social Media Addiction of High School Students

This study aims to determine the effectiveness of online group guidance services in reducing social media dependence of high school students.

The relationships between peer victimization, hostile attribution bias, and revenge: A latent profile analysis

We explored possible patterns of peer victimization among middle school and high school students using latent profile analysis, and evaluated latent class differences in demographic characteristics and their associations with hostile attribution bias and revenge. We collected self-report questionnaire data from 14,271 Chinese middle school (grades 6–8) and high school (grades 9–11) students across 43 schools located in five provinces and autonomous regions. The results indicated that there were three latent classes of peer victimization with similar profile characteristics for middle school and high school students: the non/low-victimized class, the moderately victimized class, and the highly victimized class. The frequency of peer victimization was higher for students in the 8th and 10th grades than for those in the 11th grade. Boarding school students and left-behind students were more vulnerable to peer victimization. The more serious the peer victimization suffered by adolescents, the higher was their hostile attribution bias and desire for revenge.

Vezanost za školu i adaptivno ponašanje adolescenata

The paper examines the role of school experiences in accounting for behavioural and subjective aspects of high- -school student adjustment. The study data were collected on a stratified random sample of students (N = 978) of both genders and attending all 4 grades of high schools in the Dubrovnik-Neretva County. Age and gender differences in the level and structure of relationships among the selected measures of school experiences, leisure-time variables, and adaptation outcomes were examined. Higher levels of students’ attachment and commitment to fulfilling school obligations were detected among younger students and females, while the exposure to alcohol and substance use was expectedly found to be more common among higher- -grade students. Multigroup structural equation analyses confirmed significant direct relationships of latent measures of school experiences with general satisfaction with life, and indirect relationships of the same school experiences variables with the regularity of substance use among students. Somewhat different magnitudes of structural parameters were observed between the samples defined by gender, whereas age differences in the obtained pattern of structural relationships were not supported by the empirical data.

Analyzing dynamic joint trajectories between strain and delinquency in multicultural adolescents: Application of joint trajectory modeling

This study analyzed the latent class in which the relationship between multicultural adolescents' strain and delinquency varies over time and identified the relationship between these two latent classes in order to develop intervention methods to alleviate their strain and delinquency. We utilized seven years data from MAPS of NYPI, spanning from 6th grade in elementary school to 3rd grade in high school (2013-2019). The dynamic relationships between the latent classes of strain and delinquency were analyzed using JTM, and the latent classes of these two components were analyzed using a LCGM based on a person-centered approach. Our findings revealed the existence of five distinct heterogeneous groups for strain and four for delinquency among multicultural adolescents, indicating diverse patterns of strain and delinquency behaviors. The vulnerable groups requiring welfare intervention are particularly noteworthy, constituting 17.8% of the popualtion. These groups are characterized by the following categories: S2 (“Early Low & Increasing” and S3: “Early Moderate & Increasing” in strain) and D2 (“Early Low & High Increasing” in delinquency). Given the imbalance and diversity of these latent classes, this study provides practical implications and measures for the intervention of strains and delinquency among multicultural adolescents.

Pathogenesis and Intervention Study of Idiopathic Scoliosis in Elementary and Middle School Students

Scoliosis, also known as lateral curvature of the spine or spinal lateral deviation, is a three-dimensional spinal deformity characterized by the bending of one or multiple segments of the spine to the side accompanied by vertebral rotation. It appears in the shape of an "S" or "C" and can cause pain during standing, walking, or lifting heavy objects, leading to a reduction in physical activity. Scoliosis is the most common spinal disorder among children and adolescents. Adolescent Idiopathic Scoliosis (AIS) refers to scoliosis that occurs during the teenage years and its etiology remains unclear. AIS is a spinal condition characterized by a three-dimensional deformity in the coronal, sagittal, and axial planes, with a Cobb angle of 10 degrees or more. The global prevalence of AIS ranges from 0.47% to 5.2% (Erwin et al., 2020; Konieczny et al., 2013). According to a study by Qiu Guixing et al., the prevalence of scoliosis in China is estimated to be approximately 0.6% to 2.0%, with 90% of cases being AIS. Jia Juanjuan et al., conducted a scoliosis screening of 8,026 students in Jiaxing City in 2019, with initial screening identifying 218 positive cases. Among them, 132 cases were confirmed through X-ray examination, estimating a scoliosis prevalence rate of 5.46% among primary and secondary school students in Jiaxing City. Chen Xiaosheng, Ru Shouhang et al., conducted a scoliosis survey among students from the fourth grade of primary school to the second grade of high school in various districts of Shenzhen City from January to December 2020, with the results showing a scoliosis prevalence rate of 5.01% among primary and secondary school students in Shenzhen City. The prevalence rate was higher in females than males and increased with age. If scoliosis in adolescents is not promptly and effectively treated during their growth process, the spinal deformity can rapidly progress and lead to various complications. For example, scoliosis can cause changes in the shape of the ribs, resulting in unequal thoracic cavity volume and breathing difficulties. Prolonged restricted breathing can lead to complications such as chest tightness and shortness of breath. Additionally, scoliosis can affect the functioning of abdominal organs, leading to pulmonary dysfunction and hypoxia, and in severe cases, it can cause cardiorespiratory failure. Furthermore, scoliosis not only affects the physical health of patients but also their mental well-being. The physical appearance changes caused by scoliosis deformity can potentially lead to psychological disorders.

Philippine Policies in Native Language Learning and Literacy among High School Students

The official languages recognized in the Philippines are Filipino and English, taught in educational institutions nationwide. However, the English language is more often used as a medium in teaching the curriculum, which poses a challenge for learners to develop their literacy skills, which include the ability to read, write, and speak in the Filipino language in formal learning, especially in high school (grades 7–12). Thus, this study was conducted to assess the level of practice of the Filipino-only policy and the level of literacy in the Filipino language among high school students. This quantitative study utilized descriptive, comparative, and correlational research approaches. The data were gathered from 324 high school students at a Catholic university in Western Visayas, who were chosen using a stratified random sampling. Using the mean and the standard deviation, the result showed that the levels of students' practice of the Filipino-only policy in academic-related activities and literacy in the Filipino language are high. Further, by utilizing analysis of variance for comparative analysis, the results showed no significant differences in the level of practice of Filipino-only practice and the level of literacy in the Filipino language when grouped according to grade level. Finally, using the Pearson Product-Moment Correlation, the result showed a correlation between the practice of the Filipino-only policy and literacy in the Filipino language. Based on the findings of the study, supplementary instructional materials on proposal research writing using the Filipino medium were then proposed for possible implementation.
