Abstract

Low learning outcomes in IPAS (Natural and Social Sciences) among elementary school students are often caused by limited student engagement and learning methods that do not accommodate diverse learning styles. This study aims to determine the effect of the VAK (Visual, Auditory, Kinesthetic) learning model on the learning outcomes of fourth-grade students in IPAS subjects at SD Negeri 067246 Medan Tuntungan. The research employed a quantitative approach with a one-group pretest-posttest design, involving 30 purposively selected students from class IVB. Instruments used were learning outcome tests and student response questionnaires. The test assessed students’ knowledge before and after the implementation of the VAK model, while the questionnaire gathered students' responses toward the applied learning model. Data were analyzed using a paired sample t-test with SPSS version 22. Results showed an increase in the average score from 56.27 (pretest) to 85.33 (posttest). The t-test yielded a significant value of 0.000 < 0.05, indicating a statistically significant improvement in learning outcomes after the use of the VAK model. Furthermore, 60% of students responded positively to the learning process. These results suggest that the VAK model supports student engagement and accommodates various learning styles in IPAS learning.

Abstract

Acid fast bacteria (AFB) are cell walls containing complex lipids so that in Ziehl-Neelsen staining they can bind dyes because they are not washed off by 3% HCl Alcohol (Alcoholic Acid). One of the host factors in pulmonary tuberculosis is smoking habits and exposure. Smoking habits will damage the defense mechanism of the lungs, which causes the lungs to be more easily infected with tuberculosis germs. The purpose of this study was to determine the results of analysis of acid-fast bacteria in the sputum of active smokers. The research method used was descriptive cross-sectional by examining acid-fast bacteria in the sputum of active smokers suspected of having pulmonary tuberculosis by microscopic examination of sputum (direct smear smear) using the Ziehl-Neelsen staining method. smear examination with Ziehl-Neelsen staining in patients with tuberculosis at Putri Hijau Hospital in 2022, totaling 20 samples, found 4 positive results and 16 samples with negative results.
