Exploration of Problem-Solving Skill With Inquiry-Based Authentic Learning For The Stem Program

摘要

The biggest challenge in the world of education today is ensuring that students have a good problem-solving skill, therefore serious efforts are needed to overcome these problems. This study aims to determine students' problem-solving skill through Inquiry-based Authentic Learning for the STEM program. Problem-solving skill is one of the most important components in developing the student's ability. This study has been carried out using embedded experimental design in grade X MIPA7 of SMA DU-2 Jombang which amount 32 students. Data are obtained by tests, observations, and interviews. Furthermore, the data are analyzed by paired t-Test, normalized gain, and d effect size. The results show that students' problem-solving skill were in the moderate category, which was 0.498 and the d-effect size value was strong, which was 3.293. Overall, 46% of the students were still in the novice category and 54% of the students have shifted to approach expert methods to solve problems. Most students have been able to identify the physical quantities of the problem, interpret problems in motion diagrams, use appropriate mathematical procedures, and express the conclusion.
