PDF (Tiếng Việt)
This study provides survey results on the evaluation of stakeholders about the Biological Teacher Education program (2014-2018). Stakeholders including students, alums, lecturers, staff, and employers (n = 162). The questionnaire was designed corresponding to each type of stakeholders based on 11 quality assessment standards of undergraduate training programs issued by the Ministry of Education and Training. The semi-structured interview form was deployed to collect analytical and evaluation opinions about the curriculum. This results showed that stakeholders assessed the appropriateness/response/satisfaction with the Biological Teacher Education program at a good level (3.41 ≤ M < 4.21) in terms of goals and outcome standards, the curriculum program, approaches in teaching and learning, assessment activities of students' learning results, the quality of lecturers and staff, facilities and student support services. Stakeholders proposed reforming the program regarding to develop students’ quality and competencies in line with the education trend in high school.

In this paper, vector equilibrium problems in the sense of weak and strong types are investigated via an ordering cone with nonempty algebraic interior. Firstly, analytic structure in linear spaces along with their properties is discussed. Then, these properties together with a KKM Fan lemma are used to study the existence of solutions to the underlying problems. Finally, sufficient conditions for the Zolezzi wellposedness for the reference problems are provided.

PDF (Tiếng Việt)
This paper investigates bilevel optimization problems and their well-posedness. First, many kinds of approximate solutions to such problems are defined, and then based on these approximate solutions, various kinds of well-posedness for the underlying problems are introduced. By using conditions related to the continuity properties of multivariable functions, sufficient conditions for the relationship between the mentioned well-posedness properties are formulated. Many examples are given to illustrate the obtained results.
Advantages and disadvantages of students' online learning in some high schools
Abstract

PDF (Tiếng Việt)
Online learning (OL) is studied activities performed using the OL system. This study aims to provide advantages and disadvantages of OL and suggest solutions for enhancing the OL effectiveness in high schools. The present study was accomplished using the crossing-survey module and interviews in combination with quantity and quality examination. The survey results of 2.410 students at three high schools show that the majority of students meet the requirements of OL: learning task acceptance (3,68±0,91), lesson attention (4,11±0,85), lesson discussion and building (3,28±0,91), learning task completion (3,52±0,95). However, there are still some limitations, such as weak internet connection speed, technical skills, the learning ability of students, and the interactive teaching skills of teachers. Thus, in order to improve the OL effectiveness, students need to identify the learning purpose, build a positive attitude like being being ready to accept learning tasks, actively participating in speeches, paying attention to listening, and complete the learning task.
Test design for reading comprehension of persuasive texts in accordance with the General Education Program 2018
Abstract

PDF (Tiếng Việt)
The General Education Program in Literature in 2018 identifies linguistic and literary competence as a characteristic of human resources. These competences can be expressed in reading, writing, speaking, listening skills. Reading skills for learners include literary texts, informational texts and persuasive texts. The program is also required to evaluate, which is assessed as reading comprehension skills of genre-specific text. To meet the requirements of new changes in testing and assessing reading comprehension skills under the General Education Program, this paper proposes a process to design many reading comprehension tests for students in grade 9. The result showed that a number of the test check-in comprehension skills, including objectives, matrix, content, rubric according to criteria.
Building an interactive learning environment in teaching reading comprehension fiction text for grade 10 through Edmodo education network
Abstract

PDF (Tiếng Việt)
Nowadays, the use of online-based applications in teaching is quite common globally and in Vietnam. Edmodo education network is studied and used in teaching and developing reading, writing, listening and speaking skills as a second language. This study presents the construction and interactive learning environment in teaching reading comprehension skills literary texts for students on the Edmodo learning social networking platform. Edmodo's features are exploited to organize student interaction, including Post, Assignment, Groups and Folders. Forty-five students in grade 10 at Nguyen Trai High School, Giong Trom District, Ben Tre Province, participated in an interactive Edmodo classroom to learn reading comprehension. The results obtained from the classroom interface showed that allowing students to interact, exchange and share on Edmodo has created a positive sharing learning environment and contributed to forging students' reading comprehension skills.
Using text model analysis on powtoon software to guide 6th-grade students to write the narrative text that meets text style requirements
Abstract

PDF (Tiếng Việt)
The General Education Program in Vietnamese Linguistics and Literature (2018) defines the purpose of teaching writing is “training thinking and teaching how to write”. Regarding writing teaching methods, analyzing model texts is oriented as one of the effective methods for teaching writing. To guide students to analyze texts using this method, teachers can use many different techniques and tools. In this study, the Powtoon tool combined with the measurement of the gradual release of responsibility model in order was used to help students identify the characteristics of a text style, and from there, step by step write the correct text style requirements. The study was conducted from September 2021 to January 2022, with the participation of 40 students in class 6A6, Phu Thu Secondary School, Can Tho city. The results obtained during the experimental process show that the ability to recognize text type characteristics and write narrative texts has been improved.

PDF (Tiếng Việt)
In this paper, the non-convex vector optimization problem was considered and discussed the properties of its weakly efficient solution set. Firstly, some concepts about generalized convexities of vector valued mappings were provided and studied their relationships. Next, based on the Hiriart-Urruty oriented distance function, a new nonlinear scalar function for the underlying problem was presented and investigated its pseudo semicontinuous property. Finally, these concepts and properties of the Hiriart-Urruty oriented distance function were used to formulate sufficient conditions for the existence and the connectedness of the weakly efficient solution set of the reference problem.

During the period that the entire country is concentrating on preventing the Covid-19 outbreak under the motto "pause attending to school, but not stop learning", students at all levels have been taught new knowledge by teachers through the online environment with the online form. Although the situation of the Covid-19 epidemic has been controlled, there are still many potential complications and at the same time, meeting the policy of the governing ministry to strenthen the combination of two forms: face-to-face and online in teaching. Using computers and smartphones as means of teaching and learning is the best solution at the moment. Especially, smartphones have the advantage of being integrated with additional sensors such as accelerometers, gyroscopes, pressure sensors, magnetometers, image sensors, microphones, etc. Applying the above advantages of smartphones, this essay presents the results of research to bring this device into support for students practicing Physics through the Phyphox application. This research focus on smartphone application solutions to support students in doing experiments in Grade 10 Physics.
