This study investigates the effects of the operation of science activity program on scientific literacy focusing on science cultural literacy and core competencies for pre-service teachers. 255 pre-service teachers of K University participated, and the effects of the program were examined through a paired-sample t-test with one group pretest-posttest design for science cultural literacy. Only the post-test was conducted on core competency growth perception, and differences in growth perceptions by competency were compared using ANOVA. As a result of the study, the average of pre-service teachers was higher than the pre-test for science culture literacy, and this difference was statistically significant (p<.05). In the core competency growth perception, 70.6% of pre-service teachers reported growth in scientific communication ability, and as a result of the post-hoc test using LSD, it shows statistically significant growth compared to other competencies (p<.05). Through this, it was possible to confirm the educational value of the science activity program as a way to develop pre-service teachers' scientific literacy.

The study aimed to elucidate how to design a learning environment on the premise of micro-learning (ML) and investigate its impact on website designing skills and achievement motivation among secondary school students. Adopting the experimental approach, data were collected through an achievement test, a product evaluation form, and a test to gauge motivation for achievement. The sample was divided into two experimental groups. Results revealed statistically significant differences at 0.05≥α between the mean scores of the two groups that experienced ML, irrespective of the two modes of presenting the video in the pre-test and post-test, as for the test of websites design skills, product evaluation form, and achievement motivation test. Besides, there have been statistically significant differences at 0.05≥α between the mean scores of the first experimental group that had exposure to ML using the split-video presentation style and the scores of the second experimental group that underwent ML using continuous video presentation style in the post cognitive test of website design and management skills in favor of the group that had segmented-video-presentation ML. Another salient finding is the nonexistence of significant differences at 0.05≥α between the mean scores of the first experimental group that underwent segmented-video-presentation ML and the grades of the second experimental group that received ML with continuous video presentation style in the post-application of the product scorecard of websites designing skills and the motivation test. In light of these salient findings, the study recommended using ML in teaching computer courses at different educational stages in Saudi Arabia, training computer and information technology teachers to harness ML in their teaching and using ML in designing courses at all levels of education.

Purpose: The purpose of this study was to evaluate the effects of a newly developed Introduction to Clinical Nursing (ICN) program on critical thinking skills, communication competence, self-efficacy, and clinical performance self-confidence in nursing students in their third year. Methods: One group pre-test and post-test design was used with three data collection time points (pre-test, post-test1 and post-test2). Participants were 74 third year nursing students approaching their first clinical practicum. The new program included (a) simulated clinical encounters regarding situations of assessing hospitalized patents and caring for patients with oxygenation needs, (b) objective structured clinical examination of skills, (c) lectures, and (e) field trips. Data were analyzed using paired t-tests. Results: After the ICN course, critical thinking skills(significant only between pretest and post-test2), communication competence, and clinical performance self-confidence improved significantly (p<.05). There was no improvement in the self-efficacy total score but there was significant improvement in the subscale, self-regulatory efficacy. Conclusions: The study results indicate that the ICN course may be effective in increasing critical thinking skills, communication competence, and clinical performance self-confidence in nursing students. However, the effect size was very small and modifications of this program should be considered to develop more cost-effective educational programs.

Purpose: This study was conducted to determine the effects of Mulligan's mobilization with movement (MWM) on changes in the talofibular interval in the sagittal plane in subjects with chronic ankle instability (CAI). Methods: Sixteen subjects with chronic ankle instability participated in this study. The talofibular intervals were measured from US images, and the weight-bearing lunge test was used to assess dorsiflexion of the ankle joint. Each dependent variable were measured on the both affected side and sound side in three trials in pre- and post-MWM. Dependent variables were examined with a two-way mixed-design analysis of variance (ANOVA). The two factors were side (sound side versus affected side) and intervention (pre- versus post-intervention). For post hoc analysis, paired t-tests were performed to compare the dependent variables. A p<0.05 was considered to indicate significance. Results: Dorsiflexion and talofibular interval differed significantly pre- and post-intervention (p<0.05). Post-hoc analysis revealed that the talofibular interval post-MWM was significantly less than that pre-MWM on the both the affected and sound side (p<0.05). The ankle dorsiflexion in the post-MWM group was significantly greater than that in the pre-MWM group on the affected side and the sound side (p<0.05). Conclusion: The Mulligan's MWM decreased the talofibular interval in subjects with CAI. These findings suggest that the MWM technique can change the position of the talus relative to the fibular in the weight bearing position.

This study aims to investigate the impacts on adolescents of the application of the education program for ethical consumption related to clothing in terms of their clothing-related ethical consumption consciousness, and in terms of their general ethical consumption knowledge and behaviors. Additionally, the effects of clothing-related ethical consumption consciousness and general ethical consumption knowledge on general ethical consumption behavior were examined. The program for education in ethical consumption related to clothing for adolescents was developed and applied, two surveys for the pre-post test design were conducted with high school female and male students, and a total of 158 responses were analyzed. The results of this study were as follows. 1) The results of the factor analysis and the reliability test on ethical consumption consciousness for high school students clearly showed factorial structures including Pro-environmentalism, Animal welfare, Social responsibility, and Recycling. 2) Analysis of the differences in the means of ethical consumption consciousness, knowledge, and behaviors of respondents between pre-test and post-test revealed that posttest means of all research variables after application of the education program were higher than pre-test means. 3) The ethical consumption knowledge had important medicating roles in the relationship between ethical consumption consciousness with regard to clothing and general ethical consumption behaviors. Overall, the study provides empirical evidence to support the notion that there is a need for applying an ethical consumption education program to lead adolescents to consume ethically.

Background: Breathing is the essential step of Pilates exercise and can be used to activate core muscles. Although the effects of breathing exercise on pain, breathing muscles, and cervical posture have been extensively studied, little is known about the impact of Pilates breathing on spinal posture and alignment. Purpose: To determine the effect of 3D-Pilates breathing exercise on spinal curvature and alignment of healthy adults during corrected to normal alignment. Design: One group pre-post test design Methods: Eighteen participants were given a 3D-pilates breathing exercise twice a week (20 minutes per session) for three weeks and warmed up for 10 minutes before each exercise session. To examine spinal curvature and alignment of each subject, this study used radiation free rasterstereography (Formetric III, Germany). Paired t-test and Wilcoxon signed rank test were performed to determine the difference between pre and post exercise. Results: There were statistically significant differences in height (p<.001), kyphosis angle (p<.05), trunk imbalance (p<.05), kyphotic apex (p<.01), cervical fleche (p<.05), pelvic tilt (p<.01), and lateral deviation (p<.05) between before and after 3D Pilates breathing exercise. However, there was no significant difference in lordosis angle. Conclusions: The study results indicated that three week 3D-pilates breathing exercise program could be presented as an effective rehabilitation method for improving spinal curvature and alignment.

This study was developed to evaluate the effectiveness of a multicultural education program for college students. To this end, the program was designed to offer them a series of twenty lectures for three months, 60 hours in total, and a quasi-experimental design was employed to evaluate the difference between pre-test and post-test scores of participants of both experimental group(N=45, Mdiff=.378) and control group(N=47, Mdiff=.036) on their attitudes on cultural diversity. Also, pre-test and follow-up test scores were compared to confirm whether the effect was sustained. The results showed that while the pre-post difference was statistically significant for experimental group participants(t=4.264, p=.000), the difference was not significant for control group students. Furthermore, the effectiveness of the program was sustained among students in the experimental group at a 3-month follow-up test(t=2.466, p=.016). In conclusion, the multicultural education program, in fact, proved to be effective in changing the attitudes of college students in understanding and accepting different cultures in Korean society.
