Pengaruh Effleurage Massage dan Teknik Relaksasi Nafas dalam terhadap Nyeri Punggung Bawah Ibu Hamil Trimester III

Lower back pain is a common complaint among pregnant women in the third trimester. It is estimated that approximately 70% of pregnant women experience some form of back pain during pregnancy, childbirth, or postpartum. Non-pharmacological therapies such as deep breathing relaxation techniques and effleurage massage therapy can effectively reduce pain levels in these women. This study employs a quantitative approach using a quasi-experimental research method and employs purposive sampling with a sample size of 37 participants. Data analysis includes both univariate and bivariate analyses. Most respondents (64.9%) were aged between 20 and 35 years old. Additionally, the majority (64.9%) were experiencing their first pregnancy. All respondents (100%) were confirmed to have no comorbidities. Furthermore, 73% of the participants had tertiary education (Diploma, Bachelor's, Master's, or Doctorate degrees), and 62.2% continued working during pregnancy. The results of the Wilcoxon test indicated a significant effect (p = 0.000 < 0.05), confirming that effleurage massage and deep breathing relaxation techniques effectively reduce lower back pain in pregnant women. This reduction is attributed to the stimulation of tactile fibers in the skin by effleurage massage, which inhibits pain signals. In conclusion, the findings suggest that implementing effleurage massage and deep breathing relaxation techniques is beneficial for alleviating lower back pain in pregnant women. Public health advice advocates for the application of these techniques to manage such pain effectively.

Enhancing programming learning performance through a Jigsaw collaborative learning method in a metaverse virtual space

BackgroundComputational thinking (CT) is crucial to fostering critical thinking and problem-solving skills. Many elementary schools have been cultivating students’ CT through block-based programming languages such as Scratch using traditional teacher-centered teaching methods. However, the approach excessively relies on teacher lectures, so the teacher’s teaching load is hefty, and most students cannot receive timely assistance from teachers, thus reducing students’ programming learning performance, interest, and confidence. Therefore, this study designs a Jigsaw collaborative learning method implemented in a metaverse virtual space (JCLM-MVS) for peer-to-peer Scratch programming learning to promote learners’ programming learning performance, CT, and learning attitudes. This study used a quasi-experimental research method, with 48 fifth-grade students from two classes in Taiwan’s elementary school as the research participants. One class of 24 students was randomly assigned to the experimental group using JCLM-MVS to conduct Scratch programming learning, whereas the other class of 24 students was assigned to the control group using the traditional teacher-centered teaching method.Main findingsThe study found that the experimental group of learners showed significantly better Scratch programming learning performance and attitude than the control group, and there was no statistically significant difference in CT between both groups, but both learning approaches effectively promoted CT. Additionally, the interview results showed that most interviewees stated that using JCLM-MVS for Scratch programming learning could receive timely assistance from peers, make collaborative learning more efficient and learning more enjoyable, and more intend to use JCLM-MVS for Scratch programming learning than using traditional teacher-centered teaching method due to the effective collaborative interaction mechanisms and realistic learning space provided in the metaverse virtual space.Conclusions/potential implicationsThis study presents a novel and engaging learning approach by integrating a metaverse virtual space with the Jigsaw collaborative learning method, referred to as JCLM-MVS, which enhances the effectiveness of the Jigsaw collaborative learning method in promoting Scratch programming learning performance, CT, and attitudes.
