The study is aimed at exploring impacts of self-assessment on students’ self-regulated learning and satisfaction at a university setting. Twenty-one students taking a foreign language pedagogy course participated in the study. Weekly self-assessment was assigned for 8 weeks to see if it improved students’ self-regulated learning. Student questionnaire was collected twice on the 7th and the 15th week; in addition, in-depth interviews were conducted to gather students’ perceptions of self-assessment in terms of its benefits and drawbacks. Findings based on quantitative and qualitative analysis are as follows. Firstly, significant positive impacts of self-assessment were found in all three domains of self-regulated learning: cognitive, motivational, and behavioral. Secondly, students found self-assessment overall satisfactory and useful in their studies. In-depth interviews further revealed that self-assessment helped to regulate their study behaviors effectively, which, in turn, led to a better understanding of the subject matter and greater participation in class activities. At the same time, however, some students expressed some burden as a drawback of self-assessment. Pedagogical implications and research suggestions for future study were discussed.

Over the years, in the field of safety assessment of geological disposal system, system-level models have been widely employed, primarily due to considerations of computational efficiency and convenience. However, system-level models have their limitations when it comes to phenomenologically simulating the complex processes occurring within disposal systems, particularly when attempting to account for the coupled processes in the near-field. Therefore, this study investigates a machine learning-based methodology for incorporating phenomenological insights into system-level safety assessment models without compromising computational efficiency. The machine learning application targeted the calculation of waste degradation rates and the estimation of radionuclide flux around the deposition holes. To develop machine learning models for both degradation rates and radionuclide flux, key influencing factors or input parameters need to be identified. Subsequently, process models capable of computing degradation rates and radionuclide flux will be established. To facilitate the generation of machine learning data encompassing a wide range of input parameter combinations, Latin-hypercube sampling will be applied. Based on the predefined scenarios and input parameters, the machine learning models will generate time-series data for the degradation rates and radionuclide flux. The time-series data can subsequently be applied to the system-level safety assessment model as a time table format. The methodology presented in this study is expected to contribute to the enhancement of system-level safety assessment models when applied.

This work provided a review of three techniques—(1) spectrochemical, (2) electrochemical, and (3) spectroelectrochemical– for molten salt medias. A spectroelectrochemical system was designed by utilizing this information. Here, we designed a spectroelectrochemical cell (SEC) and calibrated temperature controllers, and performed initial tests to explore the system’s capability limit. There were several issues and a redesign of the cell was accomplished. The modification of the design allowed us to assemble, align the system with the light sources, and successfully transferred the setup inside a controlled environment. A preliminary run was executed to obtain transmission and absorption background of NaCl-CaCl2 salt at 600°C. It shows that the quartz cuvette has high transmittance effects across all wavelengths and there were lower transmittance effects at the lower wavelength in the molten salt media. Despite a successful initial run, the quartz vessel was mated to the inner cavity of the SEC body. Moreover, there was shearing in the patch cord which resulted in damage to the fiber optic cable, deterioration of the SEC, corrosion in the connection of the cell body, and fiber optic damage. The next generation of the SEC should attach a high temperature fiber optic patch cords without introducing internal mechanical stress to the patch cord body. In addition, MACOR should be used as the cell body materials to prevent corrosion of the surface and avoid the mating issue and a use of an adapter from a manufacturer that combines the free beam to a fiber optic cable should be incorporated in the future design.

감성지능(EQ)은 현대 심리학에서 매우 중요한 주제이다. 전문 분야와 학교에서 이루어진 기존 연구들은 모든 사람을 대상으로 하면서 학교생활에서 학생들의 전반적인 성공을 다루고 있다. 최근 직장과 대학 캠퍼스의 감성지능에 관한 여러 연구들은 감성지능이 한국 교육 연구에 있어 그만큼 중요한 관심사가 되고 있음을 입증한다. 본 연구는 한국에서의 교육 연구와 감성지능에 대한 새로운 통찰을 마련하기 위해 한국 대학교에서 100여명 대학생을 상대로 설문조사 및 데이터분석을 통해 연구하였다. 연구결과로 첫째, 남학생의 감성지능이 여학생보다 더 높았고, 둘째, 다른 초등 및 중학생을 대상으로 한 테스트와 비교해 볼 때, 101명의 대학생 1학년의 감성지능이 초등학생과 매우 유사한 수준으로 나타났다. 그러나 정서조절능력에서는 대학생 1학년이 더 높게 나타난 반면, 정서표현 측면에서는 더 낮은 수준을 보여주었다. 본 연구의 결론은 학생들을 격려, 지지하면서 그들의 긍정적이고 의미있는 경험을 할 수 있도록 하고 정서적 학습을 향상시키는 교육적 실천의 필요성을 보여 줌으로써 한국의 교육 현장에 중요한 영향을 끼친다.

본 연구는 국내 대학의 중국어-한국어 탄뎀수업에서 학습자주도 평가 방법으로 동료평가 를 도입하여 이에 대한 학업성취도와 학습자의 정의적 태도에 미치는 영향을 분석하고, 동료 평가와 교사평가와의 일치도를 알아보고자 한다. 연구 대상은 부산 지역 대학의 2학년 중국 어-한국어 탄뎀수업 수강자 224명으로 학생들은 동료평가와 교사평가를 실시한 실험반과 교 사평가를 실시한 통제반으로 나누어 한 학기 동안의 탄뎀 학습과 3차례의 평가 활동을 하였 다. 그 결과 첫째, 실험반, 통제반 모두 학업성취도에서 긍정적인 효과가 보였다. 둘째, 학습 태도 변화에서는 실험반에서 유의미한 효과가 있는 것으로 나타났으며, 마지막으로 동료평가 와 교사평가 사이의 일치도는 비교적 높게 나타났다. 이는 동료평가방법이 신뢰할 수 있는 평가방법이자 탄뎀수업에서 충분히 활용가능성 있음을 보여주고 있으며, 학습 효과도 긍정적 임을 증명한다.

The purpose of this study is to explore changes in university students’ self-directed learning attitude through the implementation of self-assessment in a classroom setting. The current study adopted Guglielmino’s (1977) characteristics to investigate changes in students’ self-directed learning attitude over time: self-directedness, responsibility, creativity, and problem-solving. A class of 24 students enrolled in Current English Practice was observed for 15 weeks, where four self-assessment sessions were administered. After mid-term exam, a questionnaire was conducted to find out whether self-assessment helped students with their self-directed learning attitude. Additionally, in-depth interviews were conducted with four students of a group regarding possible changes in self-directed learning attitude through self-assessment in the course of time. The findings are as follows. First, the results of the survey indicated that students felt positive changes in those four characteristics of self-directed learning attitude by the implementation of self-assessment in the classroom. Second, the analysis of in-depth interviews supported the findings of the questionnaire that self-assessment provided students with opportunities to strengthen their self-directed learning attitude. However, there is a research limitation that the impact of self-assessment cannot be singled out because of the flipped learning method in class.
