Smartphone microscope based on the STEM approach as a practicum tool to improve students' scientific attitudes on Animalia

Abstract

This study aims to determine the scientific attitude and its relationship to the student learning outcomes of Animalia using a smartphone microscope based on the STEM approach as a practicum tool. This research is a quantitative approach using a quasi-experimental (Pretest-Posttest Non-Equivalent Control Group Design) and descriptive method. The scientific attitude was measured by the observation sheet and multiple-choice tests (pretest-posttest) to measure the learning outcomes. The study population was all Year 10 students at SMAN 1 Woyla, Aceh, Indonesia. The samples, class X MIA1, and X MIA2, were chosen using the purposive sampling technique. Data of scientific attitudes were analyzed using quantitative descriptive through the percentage formula, and correlation and regression tests were conducted to analyze the relation between scientific attitudes and learning outcomes. The results showed that the scientific attitudes of the two classes were in the very high category (experimental class: 94.8%, control class: 95.1%). The results of the correlation test of scientific attitudes towards learning outcomes revealed rcount (0.346)> rtable (0.254), indicating a positive effect. The regression test results showed the R2 of 0.120, indicating that scientific attitudes explained the variance of learning outcomes by 12.0%.
