Abstract

Problem solving is a mental and intellectual process in finding a problem in solving it based on accurate data and information, so that appropriate and accurate conclusions can be drawn. The HOTS question is an educational evaluation that tests higher-order thinking skills. The purpose of this study was to determine the response and whether the application of the problem solving learning model could improve students' ability to answer HOTS questions on Elemental Chemistry. The subjects of the study were students of class XII MIPA 4 SMA Negeri 7 Denpasar in the academic year 2021/2022. The object of the research study was to understand the HOTS question-oriented elemental chemistry material and student responses to problem solving learning models. This type of research is classroom action research. In this study, two cycles were used through four stages of the activity process which included (1) planning, (2) action, (3) observation, and (4) evaluation and reflection. Collecting data with the technique of assessing student test results as numerical data while data collection using observation techniques for qualitative data. The results showed that (1) the application of the problem solving learning model could improve students' ability to answer HOTS questions on elemental chemistry (2) there was a positive response to students in applying the problem solving learning model to improve students' ability to answer HOTS questions on elemental chemistry.

Abstract

The purpose of this research is to improve students' learning outcomes in Chemistry by applying the Project Based Learning learning model with the STEM approach to students' Carbon Compounds material. The implementation of this class action research was carried out in class XII MIPA 2 SMA Negeri 7 Denpasar in semester 1. The subjects of this research were class XII MIPA 2 SMA Negeri 7 Denpasar in the academic year 2022/2023, a total of 44. The object of research is the application of the Project Based Learning learning model with the STEM approach, and learning outcomes. In this study two cycles were used through four stages of the activity process which included: planning, action, observation, and evaluation & reflection. The results showed that in the initial reflection the average student learning outcomes was 70.93. In cycle I, 19 students completed and 25 students incomplete, with an average student learning outcome of 72.95 and a percentage of student activity of 42.04% which is quite active. In cycle II as many as 44 people have completed, with an average student learning outcome of 81.36 and a percentage of student activity of 60.51% which is classified as active. Thus the application of the Project Based Learning learning model with the STEM (Science, Technology, Engineering, and Mathematics) approach to carbon compounds material can improve chemistry learning outcomes for class XII MIPA 2 students at SMA Negeri 7 Denpasar in the academic year 2022/2023.
