A convergence study of oral health beliefs and subjective oral health awareness-knowledge factors of some university students was conducted on 216 students agreed from April 1 to June 14, 2019. Satistical analysis was performed with the mean and standard deviation, t-test, one-way ANOVA, and Pearson's correlation test. The oral health beliefs were 3.87 and oral health knowledge, oral health importance measured by 5-point, oral health interest and oral health status are 11.9, 1.50, 2.36, 2.67 respectively. The need for constant oral health education so that changes in oral health beliefs of university students and subjective oral health awareness-perception ability can be improved. Oral health education programs should be developed to suit the characteristics of university students.

The traditional teaching-learning in mathematics, which pursue only one correct answer, should be reexamined to cope with an age of uncertainty. In this research, Perry's epistemological development scheme was noticed as a theoretical approach to diagnose problems of dualistic mathematics lessons and to search solutions of the problems. And Design-Based Research method was adopted, We developed the epistemological development scheme through considering Perry's theory and related studies, scaffoldings and teaching-learning to enhance students' epistemological positions in mathematics. Based on these discussions we designed teaching experiment about operations with negative numbers, and analyzed its didactic implications.

This study set out to examine the knowledge about and preventive actions against musculoskeletal diseases among dental hygiene students according to the Health Belief Model, suggest a need for programs to promote health and prevent those diseases, and investigate their relations, A survey was taken among 83 sophomores and 114 juniors at the dental hygiene major of a college in Gyeonggi Province. Analyzed by using SAS 8.0 version. The findings are as follows: 1. The sophomores and juniors scored $22.50{\pm}2.37$ and $22.29{\pm}3.01$ points, respectively, on susceptibility of the Health Belief Model with significant differences between the two groups(P < 0.01). Significant differences were also found between the sophomores that scored $18.82{\pm}2.60$ points and the juniors that scored $18.64{\pm}2.77$ points on benefit(P < 0.05). 2. The juniors experienced a higher level of pain than the sophomores with statistical significance observed on the neck, shoulder, lower back, knee, foot, and ankle(P < 0.05). 3. Of the Health Belief Model, severity had significant positive correlations with 'Placing frequently used tools near the dental technician' and 'Trying to avoid repeating the same task and diversify tasks'(P < 0.01). And benefit was positively correlated with 'Trying to reduce the frequency of bending and stretching out during treatment, 'Trying not to lean much with the neck, back, arm, and wrist' and 'Trying to maintain the torso in the neutral position'(P < 0.01). The results suggest that there should be some instructions to help dental hygiene students practice the preventive actions against musculoskeletal diseases and further prevention programs against those diseases.

The purpose of this study was to investigate students' views on the scientific model and to compare their views by grade, gender, and achievement. Relationships between students' views on the scientific model and epistemological beliefs were also investigated. Participants were 137 8th- and 112 11th-graders in Seoul. The results indicated that the students' views on the scientific model, on the whole, were adequate except the items concerning the 'models as exact replicas'. Male students or high-achieving students had more adequate views on the scientific model than female students or low-achieving students. However, there was no significant difference between 8th- and 11th-graders. In correlation analysis, students with inappropriate views on the scientific model were found to have traditional epistemological beliefs.

This study aims to explore central and peripheral beliefs of mathematics teachers in the context of teaching and learning. For this purpose, this study analyzed teacher noticing of 8 mathematics teachers who are in-service in terms of mathematical beliefs using video-clips of math lessons. When the teachers in the video-clips seemed to have a teaching and learning problem, teachers who adopt noticing critized the classroom situation by reflecting his or her own mathematical beliefs and suggested alternatives. In addition, through noticing analysis, teachers' mathematical beliefs reflected in specific topics such as student participation in teaching and learning were compared to reveal their individual central and peripheral beliefs. Through these research results, this study proposed a model that extracts the central and peripheral beliefs of math teachers from the constraints of the teaching and learning context using noticing analysis. Additionally, it was possible to observe the teacher decision-making and expertise of mathematics teachers.

This study examined Korean pre-service science teachers' belief on science teaching and learning and its evolution over years in their teacher preparation programs. Juniors and seniors from two major universities, enrolled in college of education located in major cities in Korea, participated in this study. They completed BARSTL(Belief About Refrmed Science Teaching and Learning) which consisted of 32 Likert scale items. In order to investigate the evolution of their belief on science teaching and learning, the juniors responded to BARSTL again after 1 year. Results indicated that the pre-service science teachers had to some extent positive beliefs on science teaching and learning, but their beliefs were not much developed over a year.

In physics education, the research on students' conceptions has developed in the discussion on the nature and the difficulty of conceptual change. Recently, mental models have been a theoretical background in concrete arguments on "how students' conceptions are constructed or created." Mental models that integrate information in the presented problem and individual knowledge in their long-term memory have important information about not only expressed ideas but also in the thinking process behind the expressed ideas. The purpose of this study is to investigate the forming process and the characteristics of high school student's mental models about circular motion, and how they were changed by instruction. We used the think-aloud method based on the instrument for identifying student's mental models about circular motion, pretest of physics concept, mind map and interview for investigating student's characteristics. The results of the study showed that instructions based on the mental model theory facilitated scientific expressed model, but several factors that affected forming mental models like epistemological belief didn't change scientifically after 3 lessons.

Teachers' teaching behavior is directly influenced by teachers' belief, and students' belief system is directly influenced by teachers' teaching behavior. There has been a question whether curriculum of teacher training university could help preservice teachers form positive belief system. The purpose of this study was to address this issue empirically. First, a questionnaire about mathematical belief was given to freshmen preservice teachers. They generally showed positive belief about mathematics to the degree that is not satisfactory and responded most positively in the sub-area of teaching mathematics from three sub-areas of mathematics itself, studying mathematics, and teaching mathematics. After studying a mathematical philosophy course, the freshmen preservice teachers were given the same questionnaire that they responded before studying the course. Belief about mathematics itself was changed very positively, and increase in the sub-area of mathematics itself was the largest. These results show that the mathematical philosophy course helped preservice teachers form positive belief system in mathematics.
