In this article, we introduce an example about 'computers and mathematics education' and discuss its educational meaning. First, we survey two microworlds of Logo and DGS, which are two different representation systems for geometric phenomena. And we propose needs of connecting two microworlds with common perspective. And we suggest a mediation model that connects two representations in a microworld. Using this mediation model(Circle model), we construct a circle, a ellipse, and a cardioid with two different representations. It is important that the mediation model makes it possible that we translate descriptions from one representation into the other, and guess perimeters of planar curves. We also discuss roles and mathematical implications of this mediation model by error case in calculating perimeters of ellipses.

Purpose: This study was to investigate the nationwide operational status of the professional medical support staffs (PMSS) who practice the expanded roles in the hospital setting. Methods: The data were obtained through survey from 36 hospitals with over 500 beds from 25th May to 12th July 2016. Data from 1,666 PMSS were analyzed. Results: Since the job titles varied, we classified them into 5 groups according to their roles; advanced practice nurse, clinical nurse expert, PA (physician assistant), coordinator, and others. There were differences in the operation status of PMSSs depending on the region, nurse staffing grade and number of hospital beds. Qualification criteria varied from hospital to hospital, and almost half of the hospitals didn't have any qualification standards for them. There were differences in age, educational level, clinical careers, rewards, and job satisfaction in 5 groups. Especially PA group had low salary, poorer working conditions, more difficulties in performing their work, and lower job satisfaction than other groups. Most PMSS (99.5%) were using a delegated prescription authority, however only 68.3% had job description and 19.9% had documented delegated role. Conclusion: Adequate training curriculum, documented delegated roles, and the protocols for legal protection and efficient medical services are needed.

Purpose: This study set out to use a one-group pretest-posttest experimental design to develop a highly motivating CPR program for help care workers who lack CPR education, and to evaluate its effects on their knowledge about program application, attitude, and self-efficacy. Methods: For this purpose, 140 questionnaires were administered to subjects who underwent training at an educational institution for care workers in S city and G province. The program was developed from April, 25 to May, 15 in 2016, and the evaluation period was from May to July, 15. The collected data were analyzed through SPSS version 23, and a paired t-test was conducted. Results: The program spanned 240 minutes, including 80 minutes on theoretical education and 160 minutes on practical education. Knowledge of CPR in the post-test proved to be higher than that in the pre-test, from 6.4 to 9.2 (t=-15.72, p<.001),; the score on attitude increased from 38.4 to 41.7 (t=-5.89, p<.001),; and self-efficacy increased from 41.0 to 66.7 (t=-21.83, p<.001). Conclusion: The basic CPR education program emphasizing motivation was effective for the care worker trainees and could be used for other curriculum by expanding the scope of the subject.

The purpose of this study was to examine the effect of linguistic activity on young children's Creativity by applying an linguistic activity, one of the major realm of Project Spectrum, to experimental group. The following research task was established for this study. What effect does the linguistic activity through Project Spectrum on children's Creativity? The participants of this study were 80 of 5-year-old young children in two groups. They were divided and assigned into two groups, an experimental group(26 boys and 14 girls) and a control group(22 boys and 18 girls). While the experimental group was engaged in the Project Spectrums linguistic activities for 15 weeks, the control group was engaged in kindergarten curriculum linguistic activities. It was revealed that Creativity through Project Spectrum of experimental group had much influence on children's linguistic ability than control group in every field (speaking, listening, reading, and writing) by developing and applying detailed criteria for Creativity for this study.

Purpose: As health care needs for Lesbian, Gay, Bisexual and Transgender (LGBT) are becoming increasingly important, it has become imperative for the nurses to be attentive towards their health problems and provide nursing care with an open-minded attitude. Due to limited opportunity to provide direct nursing care to LGBT patients, it is hypothesized that simulation would provide good opportunity for students to experience LGBT nursing care in a safe environment. This study was conducted to develop and apply simulation of LGBT nursing care to ultimately provide unbiased nursing care for LGBT population and prepare basic data for LGBT nursing education. Methods: This study was a single-group pre-post experimental design study for 57 senior nursing students based on the comparison of existing LGBT knowledge, general attitude towards LGBT, and nursing attitude towards LGBT before and after simulation. The scenario content included discussion of coming out issue, providing sexual health information, and supportive nursing care for LGBT population. Data were analyzed with descriptive statistics and Wilcoxon signed rank. Results: Simulation education-led to a significant increase in LGBT knowledge and nursing attitude. However, there was no change in the general attitude towards LGBT. Conclusion: The results of this study suggest that LGBT education using simulation may be effective for nursing students and nurses from the point of concern for LGBT population. It is hypothesized that future LGBT educational programs might need more detailed information from both care recipients and nurses. Finally, LGBT education needs to be included in the nursing education curriculum.

The purpose of this study is to provide implications for improvement of mathematics textbook based on discursive approach to textbook analysis that complementarily combines a communicational approach to cognition and social semiotics. For this purpose, we reconstructed an analytic framework for discursive approach to written discourses of Korean textbook and CMP, and applied it to our analysis. Results show that several characteristics in meanings were developed by the use of words and visual mediators. First, in the case of ideational meaning, there were qualitative and quantitative differences between vocabularies used and between information addressed by visual mediators. Second, in the case of structural meaning, an offer and application of procedure was emphasized in a Korean textbook, whereas expectation and selection experiences of diverse possibilities for problem solving was underlined in CMP. In the case interpersonal meaning of student-author, imperative instructions were paid attentions in a Korean textbook. In contrast, students' interdependence and active participation were stressed in CMP. Therefore, this study addressed ideas about how to analyze mathematics textbooks based on integrated meanings developed by the use of words and visual mediators. In addition, it distributes implications for improvements of Korean mathematics textbooks through the analytic framework of both mathematical meanings and interpersonal meanings of student-author.

This study aims to investigate students' statistical thinking through statistical processes in different instructional settings: Teacher-centered instruction vs. student-centered learning. We first developed instructional materials that allowed students to experience all the processes of statistics, including data collection, data analysis, data representation, and interpretation of the results. Using the instructional materials for four classes, we collected and analyzed the data from 57 seventh graders' discourse and artifacts from two different instructional settings using the analytic framework generated on the basis of literature review. The results showed that students felt difficulty particularly in the process of data collection and graph representations. In addition, even though data description has been heavily emphasized for data analysis in statistics education, it is surprisingly discovered that students had a hard time to understand the relationship between data and representations. Also, there were relationships between students' statistical thinking and instructional settings. Even though both groups of students showed difficulty in data collection and graph representations of the data, there were significant differences between the groups in terms of their performance. Whereas students from student-centered learning class outperformed in making decisions considering verification and justification, students from teacher-centered lecture class did better in problems requiring accuracy than the counterpart. The results from the study provide meaningful implications on developing curriculum and instructional methods for statistics education.
