Honey Solution

Background: Ventilator Associated Pneumonia (VAP) is one of the causes of infection in the hospital and the main cause of death due to nosocomial infection. The strategy to prevent VAP is by oral hygiene. Honey may be a good solution for oral hygiene.Objective: This study aims to compare the effect of the use of 20% honey solution and 0.2% chlorhexidine as oral hygiene on VAP prevention in patients on mechanical ventilation.Methods: This was a quasi-experimental study with posttest only control group design in an incentive care unit of a general hospital in Indonesia. Thirty respondents were selected using consecutive sampling, which 15 respondents assigned in a 20% honey group and 0.2% chlorhexidine group. Clinical Pulmonary Infection Score (CPIS) was used to measure Ventilator Associated Pneumonia. Data were analyzed using Independent t-test.Results: The mean of CPIS in the honey group was 3.33 and the chlorhexidine group was 3.53. Independent t-test showed p-value 0.618 (>0.05), which indicated that there was no significant difference of the effect of honey and chlorhexidine on VAP event.Conclusions: The 20% honey solution has the same effect with 0.2% chlorhexidine in preventing VAP events in patients on mechanical ventilation.

Level Of Significance

This research is designed to investigate the use of electronic dictionary in improving students� vocabulary mastery. This quantitative research applied quasi-experimental with nonequivalent control group design by involving 65 second-grader of SMAN 1 Garawangi. There were two instruments used in this research, namely test, consisted of pretest and posttest, and questionnaire. As result, the findings showed that the mean score of experimental class on pretest was 53, and the mean score of experimental class achieved 86 after the treatment. The improvement of students� vocabulary mastery can also be seen from the level of significance (two-tailed) in paired t-test that was less than the alpha (0.000<0.05). It indicated that the null hypothesis was rejected and Ha was accepted which means that there was significant difference of means between pre-test and post-test of experimental class. Besides, most students endorsed ten items of questionnaire involving affective, behavioral, and cognitive aspects which means that most students in experimental class agreed that electronic dictionary can help them in improving their vocabulary mastery. Finally, the researcher concludes that the use of electronic dictionary can improve students� vocabulary mastery.Keywords: electronic dictionary, vocabulary mastery, quasi-experimental, nonequivalent control group

The aim of this study is to determine the effect of the 5E Inquiry Learning Model as compared to the conventional method in enhancing third-grade students’ science achievement using “magnet” as the learning material. A quasi-experimental pretest-posttest control group design was employed with the participation of 40 students from two intact Third-grade classes in a primary school in Kuala Kangsar. The experimental group was taught using the 5E Inquiry Learning Model which consists of 5 stages, namely Engagement, Exploration, Explanation, Expansion, & Evaluation, while the control group was taught using the teacher-centered conventional method. The science achievement in the learning of “Magnet” was measured using a researcher-developed test consisting of 12 multiple-choice and 8 fill-in-the-blank items. The test has sufficient validity and KR-20 reliability. Analysis of the pretest data indicates that there was no statistically significant difference (t = 1.66, p > .05) in the pretest means between the experimental and control groups. Accordingly, an independent samples t-test was used to compare students’ achievement in the posttest. The analysis of the posttest data indicates that the posttest mean in science achievement (16.05) among the group of students who had followed through the 5E Inquiry Learning Model is statistically significantly higher (t = 4.75, p < .001) than the corresponding mean (13.15) among the group of students in the control group. Therefore, it can be concluded that the 5E Inquiry Learning Model enhances the learning of science in terms of achievement among the primary students.

Objective - The fundamental scientific literacy skills of primary learners remains crucial as the STEM and Industry 4.0 thrusts begin to configurate across levels. Espousing the view that a visual fun-laden learning medium fosters learners’ understanding on natural phenomena and its scientific literacy, this research aims to examine the effect of inquiry-based science comics as a learning medium in improving primary learners' scientific literacy skills. Methodology/Technique –This study employs the quasi-experimental method, specifically, the pre-test/post-test control group design. Three levels of learners’ scientific literacy which covers scientific concepts and phenomena (LTC-1), thinking (LTC-2), and scientific inquiry processes (LTC-3) were quantitatively measured by using problem-set tests. The inquiry sequences of observing, questioning, exploring, discussing and evaluating were integral features of the inquiry-based comics and provided the direction of the learning sessions. Improvements in the learners’ scientific literacy skills were qualitatively triangulated through series of class observations, learners’ experiments and related artefacts, and post-mortem group discussion. Finding - The results show that there was a significant difference in students’ scientific literacy using the inquiry-based comic. The increase in gained score occurred in the first (LTC-1) and second (LTC-2) level of scientific literacy. The skills of making diagrams, charting data and drawing conclusions also progressed in the experimental group. This finding indicates that inquiry-based science comics provide a support platform in developing the fundamental scientific literacy skills of primary graders. Novelty - The results of this study contribute to the limited literature on the use of instructional inquiry-based science comics in order to leverage scientific literacy skills of primary years.

The purpose of this study is to examine the effect of the application of the guided inquiry learning model assisted by concept maps on the scientific literacy of junior high school students in the city of Mataram. The research was conducted through a pretest-posttest design with a non-randomized control group. The sampling technique was purposive sampling. The sample of 90 students was divided into three classes, where the first-class applied guided inquiry learning assisted by concept maps, the second class applied inquiry learning without the help of concept maps, and the third class applied conventional learning. All classes were given a pretest and posttest scientific literacy. Data in the form of pretest and posttest scores were analyzed by Analysis of Variance (ANOVA) and continued with the Least Significance Difference (LSD) test at 5% alpha. The results showed that the mean score of students' scientific literacy in the class that applied the guided inquiry learning model assisted by concept maps was significantly higher than the mean score of the conventional class. The conclusion is that there is an effect of the implementation of the inquiry learning model assisted by the concept map method on students' scientific literacy
