Di Indonesia muatan kurikulum yang berorientasi pada pengembangan berbagai keterampilan berpikir, khususnya keterampilan berpikir tingkat tinggi mulai diperhatikan dengan diterapkannya Kurikulum 2013. Dengan demikian keterampilan berpikir tingkat tinggi atau higher order thinking skills (HOTS) menjadi tujuan utama dalam proses pembelajaran, termasuk pembelajaran kimia.
Kegiatan siswa yang dominan dalam pembelajaran adalah mendengar, mencatat materi, serta mengerjakan latihan soal yang dijelaskan dan dituliskan oleh guru di papan tulis, siswa kurang dilibatkan dalam menemukan konsep sehingga pembelajaran menjadi monoton dan siswa kurang termotivasi untuk belajar. Aktivitas yang relevan dalam pembelajaran seperti mengemukakan pendapat, bertanya pada guru, dan saling berbagi informasi dengan teman jarang muncul.

Nery rahuni kirimi. 2022. Improving CHEMISTRY Activities and Learning Outcomes Using the Discovery Learning Model for Students at SMKN 2 Baubau.

This research is a Classroom Action Research conducted at SMKN 2 BAUBAU which aims to increase the activeness and learning outcomes of CHEMISTRY students by applying the Discovery Learning model. The subjects of this study were students of class X BKP in the academic year 2022/2023 with a total of 20 students. Data were collected through observation sheets and learning outcomes tests.

Based on the analysis of the results of this study, it can be concluded that the activities and learning outcomes of CHEMISTRY students of class X BKP SMKN 2 BAUBAU can be improved through the Discovery Learning model by: Providing stimulation at the beginning of learning, Exploring students' initial knowledge about the problem given, Providing related questions with everyday life so that their attention can be more focused. collect and process data, discuss and present the results of experiments/observations, draw conclusions as well as answer problems.

From the data collected then analyzed quantitatively and qualitatively. The results of the research that were achieved after being analyzed were: (1) in Cycle I, the average score of students' CHEMISTRY learning outcomes was 61.5 with learning completeness of 55% but still had to proceed to cycle II to see this treatment further. (2) in Cycle II, the average score of students' CHEMISTRY learning outcomes was 73.5 with 75% learning completeness. Because it has not reached the success indicator, it is continued to cycle III. (3) in the third cycle, the average score of learning outcomes was 84.00 with 90% learning completeness. This research ends in cycle III, because the indicators of success have achieved the objectives of this classroom action research.

Research has been carried out on the application of problem-based learning models to improve students' conceptual understanding of material change and separation of mixtures at SMK Negeri 2 Baubau. This research was conducted in the odd semester of the 2022/2023 academic year. This research is a quantitative research with a quasi-experimental or quasi-experimental approach. Data collection techniques include observation, tests and documentation. Data analysis techniques include descriptive analysis techniques and inferential analysis. The results of the analysis showed that the students' understanding of the concept of acid-base material taught with a problem-based learning model obtained an average value of 80.50. This shows that students' understanding of concepts taught by problem-based learning models is higher than direct learning. There is an increase in students' understanding of concepts through problem-based learning. This can be seen from the results of the analysis of the paired sample t test between the results of the pretest and posttest with a sig value. (2-tailed).
