The COVID-19 epidemic has caused higher education institutions in Vietnam to immediately transfer from traditional classrooms to e-learning environments. This interacts with high expectations and habits of learning and training can adversely affect the mental health of students. The purpose of this study is to validate the DASS-21 scale for use in the mental health screening in Vietnamese students when they suffer an immediate psychological reaction in the e-learning environment. Strict statistical analyzes (including Cronbach's alpha, Exploratory Factor Analysis, Confirmatory Factor Analysis, Average Variance Extracted, Average Shared Variance) have led to a well-fitting model of DASS-18 with a three-factor structure to measure the mental health of Vietnamese students in an e-learning environment. Results DASS-18 reported the rates of depression, anxiety, and stress in levels of moderate severity or above in Vietnamese students at 50%, 19.7%, and 37.3%, respectively. However, a rate of anxiety up to 43.1% by using DASS-21 indicating that many students may be misdiagnosed for the level of anxiety. Finally, linear regression analyses are used to examine the influence of socio-demographic factors on the immediate psychological responses of students to an e-learning environment in the context of the COVID-19 epidemic.
Higher education institutions are increasingly recognizing the importance of learning culture as a core factor for students' sustainable learning and development. While the development of blended learning environments in higher education institutions has been steadily increasing in recent years, but how to establish a blended learning culture in the classroom? The above problem can be solved when this study achieves its purpose to explore the factors of blended learning culture in the classroom. The focus of this study was to explore a structural equation model (SEM) of blended learning culture. A case study at the Hanoi University of Science and Technology (HUST), Vietnam was conducted and collected with a sample size large enough (339 students). The results of factor analysis have explored the core factors of the blended learning culture. The SEM analysis has achieved a first-order model of blended learning culture. And lastly, the SEM-values analysis for the existence of blended learning culture in the classroom has confirmed that they positively impact the acceptance of blended classrooms by students. Thus, a SEM of blended learning culture has provided a functional framework for educators to systematically cover all that create the success and sustainability of blended classroom culture in the classroom.
The STEM education emphasizes on Science, Technology, Engineering and Mathematics with a major focus on engineering design process that engineers require in solving challenges or problems. Kolb's model provides micro-learning activities such as experiencing, sharing and processing, generalizing and applying. Therefore, both Kolb's model and engineering design process are indispensable in K-12 STEM education. The K-12 STEM curriculum provides and guides students to complete a series of experiential tasks in engineering design process. Kolb's model explains how Science, Technology, Engineering and Mathematics are connected and integrated in each task of engineering design, while the engineering design process is an effective pedagogical approach for students to learn how to solve real problems. The purpose of this study was to explore the positive role of Kolb's model and engineering design process in K-12 STEM education from the students' perspective. The results of experimental research with 32 middle school students showed that a series of experiential tasks in engineering design process are effective activities to cultivate knowledge construction, intrinsic motivation and satisfaction of students, and stimulate students' interest in STEM fields. Contribution/Originality: The paper is the first logical analysis of the combination of Kolb's experiential learning model and engineering design process in K12-STEM education system. The findings can act as a blueprint for educators to design interdisciplinary K12-STEM curriculum. 1. INTRODUCTION The STEM education emphasizes on Science, Technology, Engineering and Mathematics with a major focus on engineering design process which engineers require in solving challenges or problems. According to National Academy of Engineering (NAE) and National Research Council (NRC) (2014), STEM education can effectively support students' awareness of the role of Science, Technology, Engineering and Mathematics in modern society. The research results of Asghar, Ellington, Rice, Johnson, and Prime (2012) show that secondary teachers feel that engineering-based hands-on activities would be particularly useful to students who wish to master math and science concepts. Margot and Kettler (2019) imply that teaching through engineering design process is an effective approach to integrate the subjects using a project-based approach as a STEM pedagogy. There are various forms of engineering design processes, but they require a cyclical process to solve a real-world problem (Margot & Kettler, 2019). However, secondary teachers notes that they have difficulty teaching science concepts as well when utilizing
While ethics instruction is now widespread, studies are still looking for different ways to integrate ethics in engineering programs. In this article, we propose a novel approach by teaching engineering ethics through a psychology course. Starting with the relevant literature studies, we have argued that the phenomeno-logical experience of ethics is a source to explain psychological truths, while en-gineering ethics can be better taught from psychological / behavioral perspectives. A pedagogical approach of experiential learning has been applied to integrate engineering ethics into the psychology course. The empirical study with 400 stu-dents in psychology courses show that teaching engineering ethics through a psychology course has a significant effect on improving the knowledge of engi-neering ethics for students. The relationship between the two pre- and post-test scores was a strong positive linear relationship. A regression equation with a slope of a straight line of 0.57 and a constant of 1.52 has been provided to predict the improvement of post-test scores through pre-test scores. This study proposes the formation of a "psychology and ethics" module in technical schools.
The neoclassical economic supporters have suggested that foreign direct investment and raw material (e.g., coal, electricity, gas, and oil) are critical economic growth inputs. Few previous studies have analyzed the relationship between foreign direct investment and energy consumption on economic growth. However, existing studies usually have applied the frequentist inference. The limitation of the frequentist inference is that, if the coefficient of the independent variable is not yet significant, then conclusions might be unreliable. By applying the Bayesian approach, the main aim of this study is to revisit the impact of foreign direct investment, electricity consumption, and urbanization on economic growth in six ASEAN countries from 1980 to 2016. The obtained outcome shows that the impact of electricity consumption is evident and positive on economic growth in both frequentist and Bayesian inferences. However, the influence of foreign direct investment is not identified by frequentist inference, while Bayesian inference provides evidence that foreign direct investment is a moderately positive impact on economic growth. The empirical result from Bayesian inference contributes to the literature on foreign direct investment modeling and could be of significant importance for a more efficient foreign direct investment attracting and achieve sustainability in the long-term.
Existing studies on the ethical perception of engineering students is based on observations among students who have been exposed to ethical courses in engineering schools. Whether the students have never been exposed to engi-neering ethical curriculum, can they perceive the specific ethical standards (such as the NSPE Code of Ethics) that apply to engineers? It is also not clear about the factors affecting the ethical perception of those students? This study aims to provide clarity in this area by examining the ethical per-ception of students who have never been exposed to engineering ethical cur-riculum. The results of quantitative analysis from survey data with 654 Vi-etnamese engineering students showed that the students have a positive per-ception of specific ethical standards that apply to engineers. Finally, the Pearson correlation analysis, exploratory factor analysis, and linear regression analysis are used to examine the effect of students 'characteristics (such as gender, student year, GPA, voluntary blood donation of students, students' opinion on technology) on the ethical perception of engineering students.
