Projection in education is one of the important bases for the implementation of the sustainable and crucial strategies to ensure the development of national education, including Vietnam. As a country in Southeast Asia with the distinctive characteristics of culture and history, Vietnam has the certain advantages and disadvantages in the development of education. In this study, the projection of Vietnamese students of each school level in the period of 2015 – 2035, was referred in comparison with the projection of the teacher resource in all school levels as one of the conditions for the basic educational development in Vietnam. The study was conducted using an integrated projection in education’s formula, combined with a census (birth rate - for students; the number of teachers from Department of Education and Training’s reports, the pedagogy students prepare for graduation - for teachers) from 32 provinces and cities of Vietnam and analyzed on the rate of population change over the years. The results showed that the shortage of the teacher resource (especially the preschool teachers) and the erratic increase in the number of the children born in the good years according to the Eastern concept were the anxious issues when developing Vietnamese education and integrating into the global development trend.

Vocational orientation is a concerned topic in the Vietnamese new general education program. However, the current high school vocational programs have not yet met the need for innovation in the student competence development orientation, thus leading to high school vocational orientation has not been effective. This study proposes a vocational school-based program approached from a new individual guidance. By using the pre-experiment and post-experiment questionnaire to evaluate the feasibility and effectiveness of the proposed program to the quality of vocational orientation, the results showed that students’ awareness of vocational school-based programs changed in a positive direction. The proposed program proves its effectiveness when applied in schools by combining the practical career experience and vocational counseling, or the combination of individual experience and social interaction in choosing a suitable career. This finding overcomes the disadvantages of the old vocational school-based program and can be applied to adapt the student competence development orientation in the Vietnamese general education program.

The article mentions the impact of the Coronavirus disease (COVID-19) pandemic on online learning in Vietnamese higher education in 2020. This is a qualitative case study, by using in-depth interviews to explore the changes in the perception, methods, and orientation of online learning of students and lecturers at a key pedagogical university when experiencing the three COVID-19 outbreaks in Vietnam. The findings show that the COVID-19 pandemic has a positive impact on the developmental orientation of online learning at the Vietnamese higher education level. Even though at the time of an outbreak, opposition and dissatisfaction with online learning occurred; but through the three outbreaks, together with the efforts of lecturers and students, online learning in Vietnam has recorded remarkable achievements. This is a prerequisite for the development of online education and the innovation of digital technology in education.

Teacher professional development (TPD) is an important component of enhancing student learning and school education quality. Vietnamese Ministry of Education and Training is reforming education, including curricula, teaching methods, and textbooks. Many requirements have to been done to effectively implement the reform, and TPD is considered a significant contribution. Using data from an in-depth interview with the principal, teacher questionnaires, and school policy-related documents, this qualitative case-study research in a selected high school for gifted students in Central Vietnam aimed to find out how TPD had been implemented in response to education reforms in Vietnamese high schools. TPD was widely perceived and respected by the principal and teachers in this case study, and these positive perspectives were transferred into practice with numerous effectively employed TPD strategies at this high school for students’ enhanced learning and achievements.

Realistic Mathematics Education (RME) has gained popularity worldwide to teach mathematics using real-world problems. This study investigates the effectiveness of elliptic topics taught to 10th graders in a Vietnamese high school and students' attitudes toward learning. The RME model was used to guide 45 students in an experimental class, while the conventional model was applied to instruct 42 students in the control class. Data collection methods included observation, pre-test, post-test, and a student opinion survey. The experimental results confirm the test results, and the experimental class's learning outcomes were significantly higher than that of the control class's students. Besides, student participation in learning activities and attitudes toward learning were significantly higher in the RME model class than in the control class. Students will construct their mathematical knowledge based on real-life situations. The organization of teaching according to RME is not only a new method of teaching but innovation in thinking about teaching mathematics.

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.

Although the social-emotional learning model (SEL) has been researched in Vietnam for many years, studies on teachers' SEL-based teaching competence have not been the focus. This study explored the possibility of applying the SEL model to the teaching of Vietnamese primary school teachers. Our case study of 50 teachers who participated in previous SEL projects highlights three factors that prevented successful SEL application in Vietnamese schools, including (a) confusion about the SEL-based teaching perspective, (b) traditional teaching methods, (c) limited training in social-emotional skills, and mental health policies for primary school teachers. The findings have broadened and deepened our understanding of the possibility of successful application of the SEL model in the classroom, which would depend on SEL-based professional supervision, consistency in SEL-based teaching methods and SEL practice guides/manuals, and promotion or adaptation of policies for SEL-based practice and application in schools.

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.

The actions, processes, objects, and schemas (APOS) theory is a constructivist learning theory created by Dubinsky based on Piaget's epistemology and used to teach math worldwide. Especially the application of APOS theory to the curriculum of a mathematics class helps students better understand the concepts being taught, which in turn contributes to the formation and development of mathematical competencies. With the aid of the APOS theory and the activity, classroom discussion, and exercise (ACE) learning cycle, this study sought to ascertain the effect of teaching derivatives in Vietnamese high schools. In this quasi-experimental study at a high school in Vietnam, there were 78 grade 11 students (40 in the experimental and 38 in the control classes). As opposed to the control class, which received traditional instruction, the experimental class's students were taught using the ACE learning cycle based on the APOS theory. The data was collected based on the pre-test, the post-test results and a survey of students' opinions. Also, the data that was gathered, both qualitatively and quantitatively, was examined using IBM SPSS Statistics (Version 26) predictive analytics software. The results showed that students in the experimental class who participated in learning activities based on the APOS theory improved their academic performance and attitudes. Additionally, it promoted the students' abilities to find solutions to problems about derivatives.
