Purpose: This study aimed to examine the effects of an eye health education program on the level of knowledge and eye health practice of middle school students. Methods: This quasi-experimental study was conducted using a pretest-posttest nonequivalent control group non-synchronized design. The study participants were from one middle school first graders in a province of Korea. The experimental group was composed of three classes (76 students), and the control group was composed of three other classes (77 students). Pretests were conducted in June for the experimental group and in August for the control group. The experimental group received an eye health education program developed for this study consisting of four sessions in total, given once a week for 45 minutes per session. The control group was instructed by the school's health teacher in the eye health education included in the existing health education curriculum. Posttests were conducted three weeks after the training in the control group and immediately after the fourth eye health education session in the experimental group. Results: After being instructed in the eye health education program, the eye health-related knowledge (t=9.45, p<.001) and eye health practice (t=2.18, p=.031) of the experimental group participating in the education program were higher than those of the control group. Conclusion: The eye health education program was effective in improving middle school student's level of eye health-related knowledge and eye health practice. School health teachers could implement this program as a part of the standard eye health education for middle school students. The long-term effects of practicing eye health behavior needs to be confirmed in a future study.

The need for artificial intelligence education has emerged, and countries around the world are announcing artificial intelligence strategies. Artificial intelligence education is reflected in the main points of the 2022 revised curriculum general published in Korea. Along with this interest, programs related to artificial intelligence education are being developed, but it is difficult to find artificial intelligence programs for lower grades of elementary school. This study aims to develop a data collection education program for the lower grades of elementary school through a series of analysis-design-development-application-evaluation processes and apply it to first-grade elementary school students to verify its effectiveness. Through the developed program, it is expected that students will be able to understand and feel interested in artificial intelligence, and develop an attitude of collecting data in their daily lives through the process of searching for various types of data in their daily lives.

This study investigated the perceptions of high school students for 8 performance assessment methods in a chemistry teacher's class by using an explanatory sequential design. To this end, a survey was conducted with 439 students from 10 high schools, and after that, 28 students from 5 schools were interviewed to interpret the survey results. The findings were as follows: First, students were experiencing a biased assessment method rather than various performance methods. Second, intuitive confirmation, relevance to a career path, and internal growth were mentioned in the performance assessment method that felt fun, and readiness and unclear evaluation criteria were mentioned in the performance assessment method that felt difficult. Third, the students recognized that it was not an appropriate performance method if the assessment result was affected by individual abilities less relevant to the chemistry subject or the assessment criteria were unclear.

Purpose: This study was conducted to develop and test the effects of a nursing information literacy competency education program for undergraduate nursing students. Methods: A non-equivalent control group pretest-posttest design was used. The subjects consisted of 42 sophomore undergraduate nursing students who had completed a fundamental nursing course (experimental group: n=21, control group n=21). The nursing information literacy competency education program consisted of 8 steps in 8 sessions, taught over 4 weeks, which was 20 hours in total. Data were collected between January 23 and March 14, 2019 and were analyzed using Chi-square test, Fisher's exact test, t-test, paired t-test, and repeated measure ANOVA with SPSS/WIN 23.0. Results: Significant differences were shown between the experimental and control groups regarding nursing information literacy competency (F=91.74, p<.001), problem-solving ability (F=52.43, p<.001), self-directed learning ability (F=36.61, p<.001), and evidence-based practice competency (F=59.66, p<.001). Conclusion: The nursing information literacy competency education program was effective in improving the nursing information literacy competency, problem-solving ability, self-directed learning ability, and evidence-based practice competency of nursing students. Hence, we recommend the nursing information literacy education program will be included as an independent course in the nursing curriculum for undergraduate nursing students to promote a needed proficiency in nursing information literacy competency.

This paper studies VPBL(Various PBL) models, applies them to classes, and analyzes results so that students of various majors can design and implement problems according to the characteristics of their majors in order to improve problem solving in education. VPBL performs the process of designing and implementing problems that reflect the characteristics of the major by applying constraints to the professor's programming language. The professor performs mini_class in the process of solving the designed problem and then shares it throughout. VPBL model apply results, The traditional teaching method was 3.51 points and the application of the VPBL model was 4.52 points, and "interaction, understanding of learning contents, and acquiring knowledge related to curriculum" were improved. In addition, VPBL has the advantage of expanding the learning range in the solving process as it is based on various problem solving, which has the effect of expanding the learning range compared to existing class models. Research on the expanded application of various SW liberal education in the future is required.
