  • Many students have dualistic beliefs about mathematics and its learning- for example, there is always just one right answer in mathematics and their role in the classroom is receiving and absorbing knowledge from teacher and textbook. This article investigated some epistemic implications and limitations of common mathematics teaching practices, which often present mathematical facts(or procedures) and treat students' errors in a certain and absolute way. Langer and Piper's (1987) experiment and Oliveira et al.'s (2012) study suggested that presenting knowledge in conditional language which allows uncertainty can foster students' productive epistemological beliefs. Changing the focus and patterns of classroom communication about students' errors could help students to overcome their dualistic beliefs. This discussion will contribute to analyze the implicit epistemic messages conveyed by mathematics instructions and to investigate teaching strategies for stimulating students' epistemic development in mathematics.

  • The purpose of this study is to explore the teaching and learning method using artificial intelligence (AI) in the mathematics classroom. To this end, to predict the direction of mathematics education using AI in the mathematics classroom, this study investigates the fields where AI is applied to education, and discuss issues to consider when introducing AI through scenario development using AI in middle school statistics. This study is meaningful in that it specifically considered how artificial intelligence can be grafted into the mathematics classroom through the development of scenarios that integrate and apply artificial intelligence that has been developed and used segmentally in the current middle school statistics. Afterwards, based on the contents of this study, implications for using AI in the math classroom were derived.

  • Objective : Stroke is the most common disabling neurological disease of adult life. And some part of the clinical symptoms and signs are correlated to the post stroke complication. This study was to analyze the therapeutic effect of the East-West collaborative treatment, especially on the motor power and the clinical symptoms and signs improvement of ischemic stroke patients. Method : For 2 weeks as possible, we observed the patients with acute ischemic stroke receiving East-West collaborative treatment. We assessed the patients using Motricity Index (MI) and the changes of clinical symptoms and signs three times at seven-day intervals. At the end of the study, we compared the results. Result : Motricity Index of patients changed from 71.55 to 76.03 (upper limb) and 73.05 to 79.42 (lower limb), respectively. Some items of clinical symptoms and signs showed the statistically significant result. Especially, the urination and defecation symptoms improved obviously. Conclusion : The East-West collaborative treatment has an effect on motor power and clinical symptoms and signs improvement of acute ischemic stroke patients.

  • Ministry of Education, Science And Technology, from 2009 to 2014, try to establish the setting of Department System in the Middle Schools and High Schools. They selected 45 Schools in 2009 and 61 Schools in 2010 for the Advanced Department System. I studied 2 High schools in 2009 and 3 High schools in 2010 of them, which located in GyeongGi-Do. I studied the Location of Department Classrooms, Teachers' Labs, Homebases and Resting Spaces of them. The conclusions are follows. 1) Most of them take Horizontal Zoning System in the Department Classrooms. 2) The Number of Teachers' Labs were increased in most of floors. On the other hand, most of Labs' Area were decreased. Every department Classroom Zone has one Teachers' Lab. 3) Every schools took much more spaces of Homebases and Resting Spaces than before. And various Resting Spaces using Corridors and Outdoors are prepared for students, those who moves every changing class time by the Department System.

  • The purpose of this study is to investigate the learning achievement of students who has taken the play-based and activity-oriented programs in the class. These new science class programs and instrument to measure student learning achievement were developed for the "Constellation Favorite" lesson of 4th grade students and Those are verified by science education experts, teachers in serve. The subjects of this study consist of 121 students in four classes who were selected on the basis of midterm examination result before teaching treatment. They were divided into two categories with two classes per each category, one class for experimental group and the other class for control group. The experimental groups were given five classes including five play-based class programs. The control groups were given five conventional instruction-type classes. The students were given questionnaires to test their interest ratings. The results show about 17% increase of their learning achievement with (p<0.005) by independent sample T-test method and 40% increase of interest rating in play-based class sample compared to normal class sample. In conclusion, the play-based science class program is found to enhance the students' learning achievement and to interest the students more effectively.

  • The purpose of this study was to evaluate the effect of interceptive primary canine extraction in palatally and buccally displaced maxillary permanent canines, and to analyze the clinical and radiographic factors affecting the treatment outcome. 97 maxillary permanent canines from 86 patients whose maxillary permanent canine were in the mesio-occlusal directions and overlapped with the roots of the adjacent teeth were analyzed. In 64 of 97 (66.0%) maxillary permanent canines, the displaced crown was completely deviated from the adjacent lateral incisor root only by extraction of the primary canine. Not only the characteristics of maxillary permanent canines such as bucco-palatal displacement direction, horizontal and vertical position of the crown tip, and presence of apical closure, but also periapical rarefaction on the primary canine and peg-shaped adjacent lateral incisor significantly affected the treatment outcome.

  • Purpose: This study investigated the characteristics and treatment outcomes of patients who visited the emergency department due to intoxication and analyzed the impact of the coronavirus disease 2019 (COVID-19) pandemic on their visits. Methods: A retrospective study was conducted using data from the National Emergency Department Information System (NEDIS) on patients who visited the emergency department due to intoxication between January 2014 and December 2020. In total, 277,791 patients were included in the study, and their demographic and clinical data were analyzed. A model was created from 2014 to 2019 and applied to 2020 (i.e., during the COVID-19 pandemic) to conduct a time series analysis distinguishing between unexpected accidents and suicide/self-harm among patients who visited the emergency department. Results: The most common reason for visiting the emergency department was unintentional accidents (48.5%), followed by self-harm/suicide attempts (43.8%). Unexpected accident patients and self-harm/suicide patients showed statistically significant differences in terms of sex, age group, hospitalization rate, and mortality rate. The time series analysis showed a decrease in patients with unexpected accidents during the COVID-19 pandemic, but no change in patients with suicide/self-harm. Conclusion: Depending on the intentionality of the intoxication, significant differences were found in the age group, the substance of intoxication, and the mortality rate. Therefore, future analyses of patients with intoxication should be stratified according to intentionality. In addition, the time series analysis of intentional self-harm/suicide did not show a decrease in 2010 in the number of patients, whereas a decrease was found for unintentional accidents.
