Domestic violence, separation and divorce are becoming increasingly common and leaving psychological traumas that are not easily healed for family members, especially for children in Vietnamese incomplete family. In this article, we identify the factors affecting the psychological trauma of children in the incomplete families by using Achenbach T. M’s Children Behavior Checklist (CBCL). We design 2 experiments and 3 steps to filter the main factor affected the psychological trauma of children living in incomplete families. In results, we found out that up to 46.42% of children had psychological traumas when living in incomplete family with an extremely high level of 8.16% and an average of 57.14%. The results showed not only by living in incomplete family but also other factors such as the pressure from public opinion and community affected the children psychological trauma. It is necessary to minimize the effect of psychological trauma of children in Vietnamese families.

Recently, researchers have paid more attention to the aspects of classroom learning environments because of their effects on students’ cognitive and effective outcomes. However, current literature reveals the lack of research that explores the factors of classroom environments in Vietnamese context. The present study, therefore, aims to validate the psychometric properties of the 25-items version of the My Class Inventory (MCI), translated into Vietnamese for 487 secondary school students. Factorial analysis showed an acceptable fit for the four-factors structure of the MCI – cohesiveness, competitiveness, satisfaction, and friction – to be appropriate for secondary school students. Internal consistency reliabilities of the general scales and four subscales were satisfactory. Results support the suitability of the MCI to assess students’ classroom environment within Vietnam’s educational context. The study recommended, among other things, that future studies should be conducted to explore the validity of the MCI on other samples of Vietnamese secondary students.

In recent years, there is a growing number of Vietnamese students applying to study abroad at a younger age. Instead of waiting until adulthood, many Vietnamese parents decide to send their offspring to study abroad early from high school. This study was conducted to analyze the factors affecting the intention of Vietnamese parents to send their children to study abroad. The dataset includes 350 responses, in which parents of middle and high school students having the intention and willingness to send their children to study abroad are respondents. The research results show that perceived value, perceived risk, and three variables of the theory of planned behavior (TPB) model affect the intention to send their children to study abroad with the ability of explanation 53.4%. In detail, Attitude (influenced by Success, Modern self, and Traditional self) has the most significant influence (30.9%) on the dependent variable. On that basis, some suggestions are proposed for international educational organizations and study-abroad counseling centers to help them give the right orientation to Vietnamese parents about studying-abroad. Besides, proposing some recommendations for domestic educational institutions, international educational institutions, and educational management agencies in Vietnam, in order to improve the quality of education and training, creating an ideal learning environment that meets international standards for students, and simultaneously attracting international students to Vietnam.

Science, technology, engineering, and mathematics (STEM) education has been successfully implemented in many countries around the world, including Vietnam. Admittedly, it appears that Vietnamese teachers are encountering several obstacles and challenges as they adopt STEM education in their classrooms. The purpose of this study was to use the Delphi method to figure out the obstacles and challenges that teachers in six northern mountainous provinces of Vietnam encounter when teaching STEM education. As per research findings, teachers confront 11 obstacles and challenges when integrating STEM education in their classrooms, including: Teacher competency, time consumption in lesson planning and guiding students to produce STEM products, teachers' beliefs regarding STEM education, inflexible programs, insufficient facilities, examination pressures, lack of timely rewards and encouragement for effective teachers, teachers’ self-funding teaching STEM, students’ competence, students’ cultural, economic and social background, and disagreements from student’s parents. These findings assist administrators and teachers in developing future strategies for successfully implementing STEM education in Vietnam.
