Along with concerns about deteriorating social and economic status of teachers around the world, Master Teacher System(MTS) has been considered as one of the alternatives to transform teaching profession into a more attractive job. In this study, the conditions and problems associated with the MTS in China is analyzed to draw implications for South Korea, which recently legalized the MTS. Research framework including four research questions is developed based on the controversies surrounding MTS of South Korea. The main findings show that the MTS in China was introduced to improve teachers' social and economic status along with the quality of prospective teachers. A very small number of master teachers are selected through rigorous standards including longer service period. They are given additional monetary and non-monetary compensations in return for their teaching-learning leadership and responsibilities. As highly respected educators, they enjoy the lifelong benefits, although they are annually evaluated. It is evident that the MTS has contributed to improving the attractiveness of teaching profession in China. Nevertheless, there are many problems associated with selection standards and methods of master teachers, their roles, compensation, evaluation and terms of service. Recent criticism due to changing circumstances surrounding education in China makes the MTS more questionable. Based on the findings, major implications for future directions of MTS of South Korea are drawn and suggested.

In the era of global aging and the retirement of baby boomers, the response is very intensive and dynamic. As baby boomers actually retire, the terms for middle-aged people have been diversified into middle-aged, midle-elderly, and the new middle, which are also evident in the training process. In line with the timing, the government and academia are also making efforts to advance the development of training courses for middle-aged, along with organizing terms for middle-aged. From this point of view, this study aims to analyze the performance of the three-year training courses (2018-2020) for the new middle at Korea Polytechnics and suggest the direction of development of the new middle training course. As a result of the study, the three-year performance of the Shin middle-aged training course gradually increased, but the completion rate and employment rate gradually decreased, indicating that countermeasures were needed. In addition, campus performance in the metropolitan area was higher than that in the non-capital area, so a plan for this deviation was needed. In addition, the need for the integrated operation of the existing 'middle-aged' and 'the new middle' courses operated by Korea Polytechnics was suggested, and measures to specialize in the new middle-aged were proposed.

Some Korean terminologies related to the structures of vascular tissues in plant morphology, written differently depending upon textbooks and dictionaries, were analysed to propose properly expressed Korean terminologies. A total of 14 university textbooks such as general biology, plant biology, and plant morphology were selected and investigated. The terminologies on the xylem structures, i.e., apotracheal parenchyma, paratracheal parenchyma, tylose, and tangential (longitudinal) section; and on the pit structures i.e., simple pit, bordered pit, aspirated bordered pit, and pit aperture; and on the stelar structures, i.e., haplostele, actinostele, plectostele, and solenostele were examined. The definition and etymology of the terminologies were traced in 4 textbooks of plant anatomy and 2 dictionaries of biology and botany written in English. And then reasonably expressed Korean terminologies, mostly written in Chinese characters, were suggested. The terminologies were compared with those that appeared in the Iwanami dictionary of biology published in Japan. It was expected that the results would contribute to promote mutual understanding between teachers and students in learning plant biology.

The purposes of National Assessment of Educational Achievement(NAEA) are to assess Korean students' achievement of the educational goals as well as to diagnose the trends of educational achievement in order to monitor the quality of education at the national level. We analysed average scores in science achievement and trend of achievement level at the National Assessment of Educational Achievement(NAEA) from the year 2003 to 2006 for 6th, 9th and 10th graders. The results are as follows: For grades 6, 9, and 10, the average scores of NAEA did not tend to increase or decrease. About the trend analysis of gender, females outperformed males for grade 6, but males outperformed females for grade 10. For grade 6, the ratio of females in Advanced level was more than that of the males in the same level. For grades 9 and 10, the ratio of male was higher than the females. For grades 6, 9 and 10, the ratio of males in Below-Basic level was more than that of females in the same level. The results of the educational achievement of urbanization shows that students in rural area scored the lowest. And the ratio of Below-basic level students was highest in rural area. It is needed that educational surroundings be improved to lessen the score difference both between genders and regions. An additional study is needed to used the results of NAEA for the improvement of curriculum and educational policy.

The Research works published in the field of Korean science education in relation to the theories of 'J. Piaget', 'D. P. Bruner' or 'J. S. Ausubel' have been analyzed and their general pattern of study were determined. Specifically, based on science education related articles published in several Korean journals, the pattern of research about the three scholars' theory is identified with the classification of the specific kind of journal, year of publication, key word, field of study, field of research, and grade of school. The journals subjected to the present study include 'Journal of the Korean Physical Society', 'Journal of the Korean Chemical Society', 'Journal of the Korean Biology Society', 'Journal of the Korean Earth Science Society', 'Journal of the Korean Association for Research in Science Education', and 'Journal of the Korean Society of Elementary Science Education'. It is determined from the present study as follows: First, the total number of related articles published in said journals is 97, and 'Journal of the Korean Association for Research in Science Education' ranks first in numbers. In terms of time period, it is found that most of the researches has been carried out during the mid 90s, and is still popular today. In addition, our key word search revealed that the 'cognitive development' by Piaget is most widely studied in the articles and biology is the area that has been most frequently studied. As to the field of research, teaching study was the one that has been most widely studied. Further, many articles have focused their studies on middle school. In conclusion, it is found that the Korean research works so far made for the theory of 'J. Piaget', 'D. P. Bruner' or 'J. S. Ausubel' are rather limited to a certain area and field, etc.

Research-based professional development is essential for in-service and pre-service science teachers across the nation. The purpose of this study was to examine in-service science teachers' and pre-service teachers' perception of the training program for professional development using advanced science laboratory equipment and experiments. Science teachers (N= 43) in science high schools and pre-service science teachers (N=189) were selected as research subjects. As a result of this study, in-service teachers and pre-service teachers recognized that they lacked understanding and experience in advanced science laboratory equipment, although they perceived the importance of its use. They wanted to attend training programs during vacation if they would have the opportunity. Both groups felt that they needed to improve their ability to operate the advanced science lab equipment, preferring to practice these instruments in the training programs. In-service teachers preferred the development of teaching and learning programs for use of the advanced science laboratory equipment. However, pre-service teachers preferred using the advanced science laboratory equipment. The study gives implications for teachers' professional development.

In this study, we aimed to examine the level of implementation of the second comprehensive plan for promoting academic libraries (2019-2023) by analyzing key statistics of academic libraries and gathering perceptions from library staff. We analyzed the changes in major statistical indicators of libraries over the past five years. Additionally, we surveyed library staff to understand their overall perceptions of the plan and their attitudes towards the 17 sub-tasks outlined in it. The analysis of 369 survey responses revealed several key findings. Firstly, most respondents comprehended the plan well and frequently utilized it for developing their libraries' development and implementation plans. Secondly, the IPA results indicated that regardless of the type of university, there should be a continuous focus on facility improvement, teaching-learning support, and expanding access to academic resources. Efforts to develop library policies and strengthen human and financial resources were identified as crucial. Thirdly, four-year universities particularly emphasized the importance of expanding access to international academic resources compared to junior colleges. Conversely, junior colleges perceived foundational skill-building programs and inclusive services as more significant than four-year universities. The application of the IPA diagonal model revealed that the performance levels of all sub-tasks were lower than their perceived importance levels, suggesting the need for strategies to enhance effectiveness in future comprehensive plan formulation.

Despite the growing attention on artificial intelligence-based automated scoring technology as a support method for the introduction of descriptive items in school environments and large-scale assessments, there is a noticeable lack of foundational research in mathematics compared to other subjects. This study developed an automated scoring model for two descriptive items in first-year middle school mathematics using the Random Forest algorithm, evaluated its performance, and explored ways to enhance this performance. The accuracy of the final models for the two items was found to be between 0.95 to 1.00 and 0.73 to 0.89, respectively, which is relatively high compared to automated scoring models in other subjects. We discovered that the strategic selection of the number of evaluation categories, taking into account the amount of data, is crucial for the effective development and performance of automated scoring models. Additionally, text preprocessing by mathematics education experts proved effective in improving both the performance and interpretability of the automated scoring model. Selecting a vectorization method that matches the characteristics of the items and data was identified as one way to enhance model performance. Furthermore, we confirmed that oversampling is a useful method to supplement performance in situations where practical limitations hinder balanced data collection. To enhance educational utility, further research is needed on how to utilize feature importance derived from the Random Forest-based automated scoring model to generate useful information for teaching and learning, such as feedback. This study is significant as foundational research in the field of mathematics descriptive automatic scoring, and there is a need for various subsequent studies through close collaboration between AI experts and math education experts.
