Differences in enamel surface hardness between soaking carbonated drinks and application of duck eggshell paste remineralization material

ABSTRACTIntroduction: The surface hardness of enamel is affected by demineralization and remineralization of enamel. Demineralization can cause the enamel surface hardness to decrease. Carbonated drinks are acidic drinks which can lower the pH of the oral cavity and cause damage to the enamel. Lost tooth minerals can be restored with remineralizing materials, one of which contains calcium. Natural materials that can help remineralization are calcium carbonate (CaCO3) which can be found in several animal shells such as marine materials, pearl snails and eggshells. Duck eggshell is one of the household wastes which is high in calcium which consists of 94% calcium carbonate. The purpose of this study is to analyze differences in enamel surface hardness between soaking carbonated drinks and application of duck eggshell paste remineralization material. Methods: This type of research is a true experimental laboratory with a pretest-posttest research design with control group design. The study sample was 8 post-extraction premolars that matched the inclusion criteria. The samples were divided into two groups which were previously soaked in carbonated drinks for 15 minutes. Group I: duck eggshell paste and group II: pasta without duck eggshell which was applied for 3 minutes 2 times a day for 14 days. Hardness measurement using Vickers hardness tester. Results: based on data analysis using paired t-test. Enamel surface hardness after immersion in carbonated drinks (mean=327.50 SD=23.33). The enamel surface hardness increased after application of duck eggshell paste (mean=467.50, SD=14.15) p=0.001. The control group also increased after the application of pasta without duck eggshell (mean=429.40 SD=29.01) p=0.002. Conclusion: There is a difference in the hardness of the enamel surface after being soaked in carbonated drinks and after the application of duck egg shell paste.

Implementation of discovery learning model to improve student learning outcomes

This study aims to determine whether the discovery learning approach for teaching mathematics has an effect on students' learning outcomes. This study is quantitative descriptive research with a pre-experiment, one-group pretest-posttest research design. The research subjects consisted of 31 students from class IXA at junior high school 36 Semarang. The students took a pretest before the implementation of the discovery learning model, and then a posttest was given after the implementation to measure the enhancement of students' learning outcomes. Pretest and Posttest findings revealed an increase in the average scores, which were 47.41 and 80.90, respectively, and the N-Gain test results showed a score of 0.61 in the moderate category. The study's findings shed light on the usefulness of the discovery learning approach in increasing the learning outcomes of class IXA students at junior high school 36 Semarang, particularly in the field of geometry transformation. From the results of the pretest, it was found that 31 students were in the low category. After learning with the discovery learning model, a posttest was carried out with the results of 7 students who were in the low category, 17 students in the medium category, and 7 students in the high category. There were significant changes in the participants' pretest and posttest scores, validating the efficacy of discovery learning strategies. Students who received instruction using the discovery learning model, in particular, had considerably higher posttest results as compared to their pretest scores. This demonstrates a significant increase in their comprehension and application of geometry transformation ideas following participation in the discovery learning technique. Through the discovery learning approach, teachers play a critical role in promoting student-centered learning.

COOPERATIVE LEARNING VS. DIRECT INSTRUCTION IN YOUTH SPORT: EFFECTS ON CHILDREN’S MOTOR LEARNING

Cooperative Learning promotes peer teaching that fosters active learner engagement and better retention and usefulness of knowledge. Research has shown that Cooperative Learning has a positive impact on motor learning in PE students. The aim of this study was to investigate whether Cooperative Learning is a more appropriate teaching approach for use in youth competitive athletics to improve children’s motor learning, compared to the Direct Instruction used so far. Using cluster random assignment, twelve Slovenian track and field groups (140 young athletes) were divided into an experimental group that completed three Cooperative Learning units (30 training sessions) and a control group. The children’s performances in four track and field skills were recorded and rated by three qualified assessors. A pretest-posttest research design was used. Nested analyses of covariance were conducted to examine whether the model (Cooperative Learning vs. Direct Instruction) affected posttest scores, adjusting for the average age of children and their track and field proficiency at baseline. Significant differences in favour of Cooperative Learning were found for three variables: track and field skills, low skipping, and crouch start. We found that Cooperative Learning is very effective in improving motor learning in youth competitive athletics and even more effective than Direct Instruction. The cooperative nature of the studied pedagogical model promotes peer teaching, giving feedback and taking responsibility, which has a more positive effect on the young athletes’ sports skills than the traditional teaching method.
