The purpose of this research is to see how far the increase in mathematical creative thinking abilities of students who are given problem-based learning models with ordinary learning models. This study was conducted in class V SD Negeri 200201 Ujung Padang in Padangsidimpuan City in the second semester with a total sample of 50 students divided into experimental class and control class with a research design using Pretest-Postes Control Group Design. Based on the results of the study of the average normalized gain through mathematical creative thinking abilities of students with high, medium, and low ability obtained a score of 0.45 higher than ordinary learning with an average of 0.21. The results of the data analysis showed that the improvement of students' mathematical creative thinking skills using problem-based learning was better than students who were given ordinary learning. From the results of the study it can be concluded that problem-based learning is one alternative to improve students' creative thinking skills, find new ideas, think flexibly so that they are more flexible and detailed.

Populasi dalam penelitian ini adalah seluruh siswa kelas VII SMP Negeri 7 Padangsidimpuan yang terdiri dari enam kelas dengan jumlah 153 orang. Teknik pengambilan sampel dalam penelitian ini menggunakan random sampling. Jadi diambil dari populasi 20% dari 153 yaitu 30 orang. Menjerat data tentang pengaruh penguasaan konsep suhu terhadap hasil belajar IPA Terpadu siswa pada materi kalor di kelas VII SMP Negeri 7 Padangsidimpuan dengan menggunakan tes sebagai teknik pengumpulan data, kemudian data hasil penelitian diolah dengan analisis deskriptif yang memberikan gambaran dari variabel dan secara analisis statistik dengan menggunakan korelasi “r” Product Moment. Hasil penelitian tentang pengaruh penguasaan konsep suhu adalah 71,97 pada rata-rata kategori “Baik”, hasil penelitian tentang IPA Terpadu pada materi kalor adalah 74,07 pada rata-rata kategori “Baik”. Dari perhitungan diperoleh thitung = 4,20 jika dibandingkan dengan ttabel pada taraf signifikansi 5% dengan derajat bebas (dk)= N - 2 = 30 - 2 = 28, diperoleh ttabel = 1,70 sehingga thitung > ttabel atau 4,20 > 1,70. Jadi hipotesis dapat diterima, artinya ada perbedaan yang signifikan antara pengaruh penguasaan konsep suhu terhadap hasil belajar siswa IPA Terpadu pada materi kalor kelas VII SMPN 7 Padangsidimpuan.

The aim of this research was to describe whether there was any significant influence of vector mastery and physic achievement in force subject at the eleventh grade students of SMA Negeri1Sipirok. The method of this research was descriptive and coorrelational. By using random sampling technique, the writer took 39 students from 120 students. Test was used to collect the data. Based on descriptive analysis, average of vector mastery was 67.5, it was categorized “enough” and the average of force subject was 76.1, it was categorized “good”. Based statistic inferential analysis by using r produc moment and ttest formula to test hypothesis, it could be gotten rcount = 0.609 and rtable = 0.316 at error level 5%. It could be seen rcount was greater than rtable (0.609>0.316). This score was compared with ttest formula,it could be gotten tcount = 4.668 and ttable = 1.686 at error level 5%. It could be seen tcount was greater than ttable (4.668 >1.686). It means alternative hypothesis was accepted. In the other words, there was any significant influence of vector mastery and physic achievement in force subject at the eleventh grade students of SMA Negeri1 Sipirok.

Penelitian ini bertujuan untuk mengidentifikasi dan mendeskripsikan profil Pedagogical Content Knowledge (PCK) mahasiswa calon guru kimia dalam merancang pembelajaran kimia sekolah berbasis media digital pada mata kuliah kimia sekolah di Program Studi Pendidikan Kimia Fakultas PMIPA Institut Pendidikan Tapanuli Selatan. Metode dalam penelitian adalah metode campuran (mixed method) yang mengintegrasikan data kuantitatif dan kualitatif secara bersamaan. Subjek penelitian ini adalah enam mahasiswa semester VI yang mengikuti mata kuliah kimia sekolah. Data kuantitatif diperoleh melalui analisis modul ajar dan media digital berbasis lima komponen Magnusson et al.(1999), sedangkan data wawancara kualitatif diperoleh melalui wawancara mendalam. Hasil penelitian menunjukkan bahwa profil PCK mahasiswa berada pada kategori baik dengan rata-rata skor modul ajar 3,25 dan skor media digital 3,14 serta rata-rata skor komponen PCK adalah 3,20 pada skala 1-4. Komponen PCK terkuat adalah orientasi mengajar kimia dengan skor 3,42 (kategori sangat baik) sedangkan komponen lainnya masih berada pada kategori baik dengan tingkat kekuatan yang belum sepenuhnya merata antar mahasiswa. Temuan kualitatif menegaskan bahwa mahasiswa telah memiliki orientasi dan pemahaman kurikulum yang relatif kuat, namun masih beragam dalam mengidentifikasi miskonsepsi siswa, mengintegrasikan media digital secara fungsional, dan merancang asesmen formatif yang selaras dengan tujuan pembelajaran. Hasil ini menegaskan bahwa pengembangan PCK calon guru kimia masih memerlukan penguatan, khususnya pada aspek integrasi teknologi pedagogis dalam perancangan pembelajaran.

Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pemahaman konsep siswa SMP Negeri 2 Portibi pada materi Suhu dan Kalor melalui pemanfaatan Phet Interactive Simulation sebagai upaya memperkuat pemahaman mereka terhadap konsep suhu dan kalor. Latar belakang kegiatan ini adalah kurangnya sarana praktikum fisika di sekolah yang menyebabkan pembelajaran suhu dan kalor lebih bersifat teoritis. Melalui pendekatan interaktif, siswa diberikan penjelasan singkat mengenai teori suhu dan kalor, dilanjutkan dengan demonstrasi penggunaan Phet Simulation, dan akhirnya siswa melakukan praktik secara mandiri dengan secara virtual. Kegiatan dilaksanakan dengan pendekatan pendampingan dan pembelajaran aktif, meliputi penyusunan modul ajar dan Lembar Kerja Peserta Didik (LKPD) berbasis PhET pada topik "Form and Changes" (Suhu dan Kalor). Hasil kegiatan menunjukkan bahwa siswa lebih mudah memahami konsep suhu dan kalor dengan melakukan eksperimen virtual menggunakan PhET untuk mengamati perubahan suhu, perpindahan kalor, dan pengaruh kalor jenis, baik secara individu maupun berkelompok.. Antusiasme dan partisipasi siswa meningkat karena mereka dapat melakukan percobaan secara virtual seperti melihat fenomena secara nyata, bukan hanya membayangkannya melalui buku. Kegiatan ini terbukti efektif dalam meningkatkan keterampilan observasi dan pemahaman konsep fisika siswa terutama materi suhu dan kalor. Pengenalan Phet Simulation ini diharapkan menjadi alternatif media pembelajaran berbasis praktik yang dapat diterapkan lebih luas di sekolah lain.
