The research paper presents the results of an experimental research of the development of critical thinking in third-year students majoring in 013 "Primary Education" in studying a special course "From Reflection to Self-Assessment: Critical Thinking Skills" (based on Lauren Starkey methodology). The research was conducted during the first half of 2019-2020 academic year. The sample representativeness was ensured by the method of random selection, the strategy of randomization according to the criteria of age, gender, level of academic performance was described. Given the confidence interval p=95% and the confidence interval of the error Δ=±0.05, the sample size was 94 people, including of the experimental group and 49 students of the control group. The peculiarities of the development of such critical thinking skills as reflective thinking, self-analysis, awareness of one's own achievements and shortcomings, choice of problem-solving strategy, use of cognitive models of learning are revealed. It was found that the development of critical thinking was achieved through a comprehensive combination of self-assessment and reflection, performing exercises to develop the ability to clearly articulate the problem, find, analyse and interpret relevant information, draw the right conclusions and explanations.

A service robot can identify its own position relative to landmarks, the locations of which are known in advance. The main contribution of this research is that it gives various ways of making the self-localizing error smaller by referring to special landmarks which are developed as high gain reflection material and coded array associations. In this paper, the authors propose a set of indices to evaluate the accuracy of self-localizing methods using the selective reflection landmark and infrared projector, and the indices are derived from the sensitivity enhancement using 3D distortion calibration of camera. And then, the accurarcy of self-localizing a mobile robot with landmarks based on the indices is evaluated, and a rational way to minimize to reduce the computational cost of selecting the best self-localizing method. The simulation results show a high accuracy and a good performance.

This article examined the effects of self-reflecting journal writing in speaking class on academic performance of science and engineering students. To assess the effect, 27 science and engineering students from the "Speech and Life" class were asked to keep a self-reflecting journal. Pre and post-intervention surveys were conducted, followed by the analysis of learning effect and satisfaction. In addition to the pre and post-intervention surveys, an additional survey on speaking ability was conducted at the same time and the change of the students' ability was assessed. Results showed that after writing self-reflection journals, participants' learning effect and satisfaction has increased, and their speaking performance was also improved.

Purpose: The purposes of study was to evaluate the effect of debriefing using reflection questions and writing on the critical thinking disposition, self-efficacy, and clinical judgement ability in simulation of post-operative care of abdominal surgery. Methods: The research method was a nonequivalent control group no-synchronized design. The study period was from August 22 to 30, 2016. The subjects were comprised of 34 people in the experimental group and 36 in the control group. In a simulation session for post-operative care of abdominal surgery, the treatment of the experimental group was to debrief for 30 minutes using Lasater's reflection questions and writing. For the control group, a typical debriefing was conducted in the same environment. Results: Critical thinking disposition, self-efficacy, and clinical judgement were significantly higher in the experimental group than the control group. Conclusion: To enhance the critical thinking disposition, self-efficacy, and clinical judgement of nursing students in simulation, it is recommended to debrief using reflection questions and writing.

평면파 반사 계수는 수중에서의 음파에너지에 관한 해저 바닥의 모든 정보를 담고 있고 음향 해석 모델의 입력 값으로도 사용할 수 있는 음향학적 물리량이다. 본 연구에서는 실험실 수조 환경에서 입자 매질 ( 세 종류의 유리구슬, 모래 )의 평면파 반사 계수, 음속 및 감쇠계수를 측정했다. 반사 실험은 수조의 한계를 고려해 $28{\sim}53^{\circ}$의 입사각과 중심 주파수 100kHz의 협대역 신호를 이용해 수행했다. 자기 교정법 (Self-calibration method)을 이용해 측정된 자료로부터 반사 계수를 계산했고 측정된 반사 계수의 경향 및 실험의 불확실성을 서술했다. 입자 매질의 음속 및 감쇠계수는 거리 수신 신호간의 회귀분석을 통해 계산했다. Biot 이론을 이용해 측정된 음속과 감쇠계수로부터 다공율과 침투율을 추정하고 실제 지질학적 측정값과의 유사성을 확인했다. 최종적으로 추정된 다공율, 침투율을 이용해 이론적 인 반사 계수를 계산하고 반사 실험의 측정값과 비교했다. 본 실험 결과는 Biot 이론으로 일관성 있게 입자 매질의 음향학적 물성을 설명할 수 있음을 입증한다.

The purposes of this study were to identify and analyze students' attitudes and satisfaction to the portfolio process and assessment for the Introduction to Clinical Medicine course at Ewha Womans University School of Medicine in Seoul, Korea. The subjects consisted of 64 medical school students. Questionnaires consisting of 20 5-point Likert-type items were developed, including three question domains: 1) orientation, 2) portfolios in general, 3) individualized feedback. The mean and median were found and frequency analysis was performed to identify the common characteristics of the participants. A major finding was that 54.7% of the respondents felt that the self-reflection involved in building the portfolio was a valuable learning experience. Plus, the majority of respondents perceived that the individualized feedback had a positive tone and its contents were specific, practical, and constructive. The students perceived that building and writing portfolios heightened their understanding of exit learning outcomes and enhanced their reflective thinking and self-directed learning skills. Meanwhile, some students perceived that there was too much paperwork in the portfolio process and that the process was time consuming. Furthermore, 32.8% of the respondents said that they had difficulty establishing their learning strategies by themselves and self-directing their learning during the portfolio process. In conclusion, it is expected that building a portfolio can help students not only to enhance their ability to accumulate and use their personal learning resources but also to develop the professional qualities required by doctors, such as self-directed learning, self-reflection, lifelong learning, team work, organizational skills, time management and prioritization, and professional thinking and behavior.

Purpose: The purpose of this study was to identify clusters of nursing competency, and investigate the influence of reflective thinking, team learning climate, and learning organization building according to nursing competency clusters. Methods: Participants were 244 clinical nurses who worked in 4 general hospitals in Gwangju Metropolitan City. Data were collected by self-report questionnaires during June and July, 2011. Nursing competency, levels of reflection hierarchy, team learning climate, and learning organization building were measured. Data were analyzed using frequencies, means, t-test, one-way ANOVA, Pearson correlation coefficients, and K-means cluster analysis with SPSS/WIN 20.0 version. Results: Nursing competency correlated positively with intensive reflection, reflection, team learning climate, and learning organization building (p<.001). There were three clusters of nursing competency in a clinical ladder, which were derived from cluster analysis, grouped as high, middle, and low competency. Intensive reflection, reflection, team learning climate, and learning organization building showed significant differences according to grouping of nursing competency. Conclusion: The results indicate that developing intensive reflection, reflection, team learning climate, and learning organization building would be useful strategies for enhancement of nursing competency.
