This study aims to apply the model Principal component Analysis to reduce multicollinearity on variable currency exchange rate in eight countries in Asia against US Dollar including the Yen (Japan), Won (South Korea), Dollar (Hongkong), Yuan (China), Bath (Thailand), Rupiah (Indonesia), Ringgit (Malaysia), Dollar (Singapore). It looks at yield levels of multicolinierity which is smaller in comparison with PCA applications using multiple regression. This study used multiple regression test and PCA application to investigate the differences in multicollinearity at yield. From this research, it can be concluded that the use of PCA analysis applications can reduce multicollinearity in variables in doing research.

The first step towards discussing a phenomenon or a concept in depth and with powerful scientific principles and methodology is to develop, adapt and utilize tools that accurately measure and discover the problem. For this purpose, the present study concentrated on paternalistic leadership, which is a new concept in the field of management, and reliability and validity studies on the scale (PLS) that was used to assess paternalistic leadership by Cheng et al. (2004) were conducted to add the scale to the national literature. The study was conducted on the data collected from 326 (EFA) + 255 (CFA) research assistants to determine the validity of the scale. In a determination of the reliability of the scale, item-total point correlations and Cronbach’s Alpha internal consistency coefficient were used. In order to determine how the scale works in different cultural and qualitative samples, the adaptation version was discussed by comparing with the previous factor analysis studies of the PLS. The analysis showed that adaptation version of the PLS, with the structure of its 3 sub-dimensional and 23-items, will able to be used in studies aiming to determine the characteristics of paternalistic leadership in the organizational structure and management processes of universities for the researchers working in the field of higher education.

Understanding the structure of energy literacy is of importance to provide an effective energy education. This article reports the difference in attributes of energy literacy by applying the energy literacy structural model proposed in our previous study through lower secondary school students in Thailand (N = 635) and Japan (N = 1070). Results indicated that Thai students scored higher than those of Japan except the basic energy knowledge and awareness of consequences. On the other hand, the amount of basic energy knowledge did not affect to increase the entire energy literacy of Japanese students. Moreover, mean values of Japan tended to decrease with the school year progression. The energy literacy model was able to support our previous outcome that the awareness of consequences plays a critical role to link between basic energy knowledge and energy-saving behavior. The social expectations or pressures may affect the structure of energy literacy of Thai students. This study suggested that the energy education required in Thailand is to enable students to derive solutions by their own critical thinking based on knowledge relevant to the energy and environmental issues. While, for Japan, it may be necessary to implement energy education as early as possible to enhance students’ awareness of consequences in an appropriate manner incorporating with family participation and visiting energy-related facility. These findings contribute the development of energy education for improving energy literacy in an effective manner.  

This paper sought to look at collaboration as an effective tool for mathematics classroom instruction. Four preservice teachers in a qualitative case study taught mathematics to three senior secondary school classes in two secondary schools in Northern Nigeria for a period of 15 weeks spread over three years. During this period 12 students volunteered to participate in four focus group discussions on the effectiveness of the pedagogy in their classrooms. Observations, research journals and focus groups were used to collect data for the study. A Narrative approach to data analysis was used to analyses the data collected. The findings of the study suggested that, the preservice teachers had initial challenges introducing the framework into their classrooms, they, however, gradually adopted the pedagogy into their classroom teaching. The study suggested that the preservice teachers used collaborative groupings and higher ordered questions to foster collaboration among their students. Some benefits of this strategy were also highlighted from the study. Prominent among them was the effective teacher-student and student-student relationship, help students see mathematics problems as common problems and reduced the domineering attitude of mathematics teachers who see themselves as possessing the monopoly of knowledge. Other findings observed in the study include the replacement of the teacher-centered approach to teaching with a student-centered approach. Therefore, it is suggested that, if collaboration is introduced into Nigerian mathematics classrooms, the traditional teacher-controlled mathematics classroom instruction that has bedeviled our classrooms will be reduced, and a new student-centered learning approach will be put in place.

The aim this qualitative study is to determine current situation of policy on teacher employment model in Turkey from the perspectives of contracted teachers. The sample of the study consisted of 24 forms and branch teachers who were determined with the method of convenience sampling. The inclusion criterion for the sample was being contracted teachers who were employed in the provinces of Erzurum and Sanliurfa in Turkey in the academic year of 2017-2018. The data of the study was collected by using a semi-structured interview form consisting of open-ended questions. The data was analyzed by using the qualitative research method of content analysis. The findings of the study were discussed under the themes of the objective of contracted teaching, its negative aspects, and the future of the practice and solution recommendations. According to the results of the study, the vast majority of the participants were aware of the objectives of the practice of contracted teaching. The participants thought that the practice provided continuity in instruction-teaching and teachers at the schools they were appointed to. The vast majority of the participants were of the opinion that the practice of contracted teaching led to status discrimination as tenured-contracted teachers, and this reduced their motivations and organizational commitment. They stated that this practice carried negative aspects in terms of postgraduate education and being prospective teachers.

The purpose of this research is to test the theoretical model developed for the mediator role of perceived organizational support in the relationship between organizational identity and organizational stress. The research is conducted with 320 teachers who work in preschools, primary schools, elementary schools, and high schools. The data were collected using organizational stress scale, perceived organizational support scale, organizational identity scale, and personal information form. The direct and indirect relationships between perceived organizational support, organizational stress, and level of organizational identity were analysed using the Structural Equation Model. The proposed structural model was verified by the analyses. It is observed that the relationships between all variables in the research have significant values and their goodness of fit indices were within the acceptable level. The results of the analyses showed that, organizational identity significantly predicts organizational stress and perceived organizational support. It was also found that the impact of organizational identity on organizational stress was fully mediated by perceived organizational support. According to these results, organizational support plays a mediating role in the relationship between organizational identity and organizational stress.

This article introduces the concept of the carrying capacity of data (CCD), defined as an integrated, evaluative judgment of the credibility of specific data-based inferences, informed by quantitative and qualitative analyses, leavened by experience. The sequential process of evaluating the CCD is represented schematically by a framework that can guide data analysis and statistical inference, as well as pedagogy. Aspects of each phase are illustrated with examples. A key initial activity in empirical work is data scrutiny, comprising consideration of data provenance and characteristics, as well as data limitations in light of the context and purpose of the study.  Relevant auxiliary information can contribute to evaluating the CCD, as can sensitivity analyses conducted at the modeling stage. It is argued that early courses in statistical methods, and the textbooks they rely on, typically give little emphasis to, or omit entirely, discussion of the importance of data scrutiny in scientific research. This inattention and lack of guided, practical experience leaves students unprepared for the real world of empirical studies. Instructors should both cultivate in their students a true respect for data and engage them in authentic empirical research involving real data, rather than the context-free data to which they are usually exposed.

This study uses structural equation modeling (SEM) analysis techniques, with the aim of testing the structural effect of family support, entrepreneurial training, on entrepreneurial intentions, with self-efficacy and student achievement motivation as mediators. A total of 203 students participated in this study, through a questionnaire distributed online. The SEM analysis was performed using the Amos 24 App. The results showed that the family environment and entrepreneurship training had a direct and indirect effect on entrepreneurial intentions through self-efficacy and student achievement motivation. The model proposed and tested in this study can be a constructive guide for related parties in an effort to promote students' entrepreneurial intentions.

Private universities in Indonesia need to urgently enhance the lecturers' organizational citizenship behavior (OCB), especially in overcoming a transition period of learning patterns after the COVID-19 pandemic from online to offline. Therefore, this research explores employability, personality, and talent management affect OCB and proves job involvement mediates employability, personality, and talent management influences OCB. It was conducted through a survey using a Likert scale questionnaire with 230 participants of lecturers from Indonesian private universities. Path analysis supplemented by descriptive and correlational analysis was used as a data analysis technique. The results showed that employability, personality, talent management, and job involvement significantly affect OCB. In addition, job involvement mediates employability, personality, talent management influences OCB. Therefore, a new empirical model regarding employability, personality, and talent management affect OCB with job involvement mediation was developed. Accordingly, researchers and practitioners can utilize for the model in their future activities.

This study aims to explore the relationship between proactive behaviors, teaching performance, and organizational support among vocational college teachers. Based on the theory of organizational support, we conducted a survey of 373 teachers from four vocational colleges in Shanxi Province, using scales for proactive behaviors, organizational support, and teaching performance. The results indicate that: (a) There is a significant correlation between teachers' proactive behaviors and teaching performance; (b) There is a significant correlation between teachers' proactive behaviors and organizational support; (c) Organizational support plays a significant mediating role in the relationship between teachers' proactive behaviors and teaching performance. This study enriches the application of organizational support in vocational colleges, providing empirical evidence for improving teachers' proactive behaviors in higher education institutions, which could be useful for central or local education policy decision-makers and implementing units. Additionally, this model could be further applied beyond vocational education to other contexts or policies, demonstrating both theoretical and practical significance.

This article is aimed at integrating the Technological Pedagogical Content Knowledge (TPACK) system with the Didactic Suitability Criteria (DSC) of the Didactic-Mathematical Knowledge and Competences (DMKC) system to improve the reflection of prospective mathematics teachers on online classes. Thirteen prospective teachers, divided into two subgroups, participated in a training cycle that addressed both models. Each participant used and created indicators of reflection of the assigned model to analyze an online class on functions, and subgroups exchanged reflections to examine the class from the other model’s perspective. It was noted that the DMKC model allows for a broad analysis of the class but has limitations in assessing technology and the teacher's technological knowledge, while TPACK’s emphasis is on technology and teacher knowledge but does not explicitly address mathematical interaction or affective aspects. It is concluded that combining the TPACK model and the DSC of the DMKC model can generate more complete tools to reflect on online math classes and consequently allow for a comprehensive evaluation that covers both the mathematical content and the technological and pedagogical skills of the teacher.
