Penerapan Model Pembelajaran Problem Solving untuk Meningkatkan Hasil Belajar Kimia Siswa Kelas XI SMA

Abstract

This study aimed to determine the increase in student learning outcomes in the domain of knowledge, skills, and attitudes by using problem-solving learning models. The method used is classroom action research through two learning cycles consisting of the stages of planning, implementing, observing, and reflecting. There was an increase in learning outcomes and the number of students who met the minimum completeness in the domain of knowledge seen from the average value of students in cycle 1 to cycle 2. The learning outcomes of students in the domain of skills from the observation were included in the sufficient criteria in cycle 1 and increased to be good criteria in cycle 2. Classical completeness based on the number of students in cycle 1 to cycle 2 has increased. The learning outcomes of students in the domain of attitudes through the results of observation data were included in the sufficient criteria in cycle 1 and increased to be good criteria in cycle 2. As well as an increase in completeness seen from the number of students in cycle I to cycle II. Based on these findings, this model can be used to improve the chemistry learning outcomes of students in class XI.

Model Discovery Learning Berbasis STEAM: Dampaknya Terhadap Hasil Belajar IPA dan Keterampilan Proses Sains Siswa

“…Guru lebih banyak menerapkan model konvensional dengan metode ceramah dan minim aktivitas siswa. Aktivitas siswa yang menggunakan keseluruhan indera dalam kegiatan belajar mengajar akan meningkatkan penguatan ingatan serta perubahan sikap sehingga hasil belajar lebih tahan lama (Lubis, 2021). Belajar bermakna tidak akan terwujud hanya dengan mendengarkan ceramah atau membaca pengalaman orang lain.…”

“…Penerapan model discovery learning yang berbasis STEAM membantu siswa untuk terbiasa menerapkan komponen STEAM dalam kehidupan sehari-hari dimulai dari proses pembelajaran (Adlina, 2022;Roshayanti & Purnamasari, 2021) (Adlina, 2022). Model discovery learning berbasis STEAM berpengaruh terhadap keterampilan proses sains dan hasil belajar siswa, karena model pembelajaran ini melibatkan proses pemecahan masalah dalam kegiatan pembelajaran sehingga siswa berperan aktif dan berdampak pada peningkatan kemampuan kognitif siswa (Lubis, 2021). Serta dalam prosesnya, pembelajaran dengan model discovery learning berbasis STEAM berdampak pada keterampilan proses sains siswa karena memerlukan sikap sains dalam prosesnya.…”

Application of STEM-based LKPD on Reaction Rate Material to Improve Students' Critical Thinking Ability

“…According to (Bararah, 2022), one of the most important things that a teacher must understand during the teaching process is teaching strategies. To achieve optimal learner competence, in designing learning programs and learning activities for learners, educators must pay attention to the attitudinal characteristics of learners (Lubis, 2021). Based on some research previous research, developing learning media learning media development is needed to be able to overcome problems in the learning process learning process (Silaban & Panggabean, 2022).…”
