Abstract

Penelitiaan ini bertujuan untuk meningkatkan kemampuan penalaran matematis peserta didik menggunakan model pendekatan problem based learning. Subjek  penelitian ini adalah seluruh siswa kelas X AKL 1  SMK Negeri 7 Medan yang berjumlah 36 siswa. Penelitian dilaksanakan dalam tiga siklus, yaitu siklus pertama terdiri dari dua pertemuan, siklus kedua terdiri dari dua pertemuan, dan siklus ketiga terdiri dari dua pertemuan. Instrumen yang digunakan dalam penelitian ini adalah pedoman observasi, tes siklus, angket respon siswa, pedoman wawancara, dan dokumentasi. Hasil penelitian menunjukkan bahwa kemampuan berpikir matematis siswa kelas X AKL 1  SMK Negri 7 Medan meningkat dibandingkan pada Siklus I, Siklus II dan Siklus III. Hal ini ditunjukkan oleh 32 siswa atau 89% mengalami peningkatan kemampuan berpikir matematis berdasarkan total skor setiap dimensi kemampuan berpikir matematis. Rata-rata persentase hasil tes meningkat dari 45,95% pada Siklus I menjadi 73,41% pada Siklus II dan  89,52% pada  kategori tinggi pada Siklus III. Berdasarkan observasi, pelaksanaan pembelajaran dengan menggunakan model PBL sudah baik dan sesuai dengan karakteristik PBL. Hal ini tercermin dari peningkatan  rata-rata tingkat keterlaksanaan dari 71,43% pada Siklus I menjadi 85,71% pada Siklus II dan  100% pada Siklus III. Berdasarkan data wawancara dan angket, respon siswa terhadap pembelajaran matematika ditinjau dari kemampuan berpikir matematis tercatat mengalami peningkatan dari Siklus I, Siklus II, dan Siklus III. Model PBL menunjukkan respon positif pembelajaran matematika pada siswa sehingga berdampak pada peningkatan kemampuan penalaran matematis.

Abstract

The low results and activities in mathematics learning are the main basis for this research. The aim of this research is to see how well the Problem Based Learning (PBL) model can improve students' mathematics learning outcomes and activities. The research was carried out at SMK Negeri 7 Medan. This research uses Classroom Action Research (PTK). The respondents of this research were class X AKL 3 students at SMK Negeri 7 Medan, consisting of 35 people. Data collection techniques use observation and test techniques. Data collection instruments used observation sheets and essay tests. The research results showed that student activity in cycle I was 70% (good) and in cycle II it was 90% (very good). Then the students' classical learning results in cycle I were 57.14% (Medium) with an average of 76.36 and in cycle II it was 88.57% (Very high) with an average of 87.71. So the conclusion of this research is that through the application of the Problem Based Learning (PBL) learning model, it can improve students' mathematics learning outcomes and activities in statistics material in class X AKL 3 SMK Negeri 7 Medan.

Abstract

This research is based on the low interest in studying mathematics in class The type of research used is Classroom Action Research (PTK). The subjects in this classroom action research were 35 students of class X ULP 1 SMK Negeri 7 Medan consisting of 8 male students and 27 female students. The instruments used in this research were observation sheets of student and teacher learning activities, student interest questionnaires and test sheets. Based on the results of research that has been carried out in two cycles in this study, it is concluded that the application of the project based learning (PjBL) learning model with the help of interactive PowerPoint can increase students' interest in learning statistics. This can be seen from the increase in students' interest in learning from before the research was carried out (pre cycle) amounting to 48.2% (Poorly Good) to 73.38% (Good) after the first cycle and increasing again after the second cycle, amounting to 81.6% (Very good). Student statistics learning outcomes also increased from before the research was conducted (pre-cycle) by 50.8% (Poorly Good) to 73.73% (Good) after the first cycle and increased again after the second cycle of 81.30% (Very Good ).

Abstract

The primary objective of this study is to ascertain the degree to which the implementation of the Problem Based Learning methodology can enhance students' interest in statistics content and mathematics learning outcomes. This investigation is a two-round classroom action research project. The study sample comprised 34 pupils enrolled in class X MPLB 5 at SMK Negeri 7 Medan. The process of gathering data was conducted via observation, questionnaires, and assessments. During the data collection phase, both teacher actions pertaining to the management of learning activities and student engagement in problem-based learning activities are assessed. Questionnaires are employed to determine the degree of interest that students have in mathematics courses. Subsequently, learning outcomes assessments are implemented to determine the degree to which pupils have comprehended the material. Based on the examination of research outcomes, one may deduce that the implementation of the Problem Based Learning pedagogical approach has resulted in enhanced scholastic performance and heightened student engagement with mathematics, particularly with regard to the domain of statistics. The observed performance increase is evident in the report of progress, which indicates a rise from 65% in the pre-cycle to 70% in cycle I, and subsequently to 95% in cycle II. The survey responses indicate that the proportion of students who are enthusiastic about acquiring knowledge in the field of mathematics rises as they progress from the pre-cycle stage to cycles I and II. More precisely, the proportion of pupils classified as "good" rose from 61.53% in the pre-cycle phase to 73.72 % in cycle I, and subsequently climbed to 87.73 percent in cycle II. The results of student learning assessments also demonstrate an upward trend. The proportion of accurate responses was 65.73% in the pre-cycle phase, 71.17% in cycle I, and 85 % in cycle II. Therefore, it can be inferred that the Problem Based Learning instructional strategy possesses the capacity to enhance students' scholastic performance and cultivate a passion for the study of mathematics

Abstract

Yayasan Pendidikan Hafnan Simbolon terdiri dari tingkat satuan pendidikan dari TK sampai SMP yang berlokasi di Kecamatan Patumbak Kabupaten Deli Serdang. Jumlah guru di Yayasan Pendidikan Hafnan Simbolon berjumlah 15 orang.  Dalam konteks sumber belajar, guru bukanlah satu-satunya sumber belajar serta tidak hanya belajar teori-teori dari buku saja. Lingkungan sekolah dapat dimanfaatkan menjadi sumber belajar. Pemanfaatan lingkungan sekolah agar siswa diberikan kesempatan yang seluas-luasnya untuk aktif menggali informasi tentang segala sesuatu yang ada disekitarnya dan kemudian dihubungkan dengan pembelajaran yang ada disekolah. Kegiatan pengabdian ini bertujuan untuk mensosialisasikan pemanfaatan lingkungan sekolah sebagai sumber belajar, karena lingkungan merupakan sumber belajar yang kaya dan menarik untuk siswa dalam peroses belajar. Peserta kegiatan PKM adalah guru-guru di Yasayan Pendidikan Hafnan Simbolon. Kegiatan dimulai dengan mengurus perizinan dan persiapan. Pelaksanaan PKM dilakukan melalui metode presentasi, evaluasi dengan memberikan kuisoner, dan melakukan refleksi. Hasil yang diperoleh dari kegiatan sosialisasi dapat meningkatkan pengetahuan  sebesar 86,75% dengan kategori baik.

Abstract

Peningkatan kemampuan guru harus dilakukan dengan pelatihan dalam pengembangan media pembelajaran. Berdasarkan hasil wawancara dengan Kepala Sekolah dan beberapa orang guru SD IT Darrusalam diperoleh informasi bahwa jumlah guru di sekolah tersebut ada 9 orang dan jumlah ruangan kelas ada 6 ruangan. Kurikulum yang digunakan adalah K.13. Proses kegiatan belajar mengajar dilaksanakan pada pagi hari. Siswa /siswi SD IT Darrusalam  berjumlah 122 orang. Mayoritas penduduk masih taraf ekonomi rendah sampai menengah dimana masih banyak dari wali murid yang bekerja sebagai buruh dan wiraswasta. Di SD Swasta IT Darrusalam  guru – gurunya belum punya wawasan dan pengetahuan dalam mengembangkan dan menggunakan media pembelajaran yang berbasis IT. Hal ini dikarenakan kurangnya pengetahuan mereka tentang penggunaan aplikasi – aplikasi sebagai media pembelajaran. Metode yang digunakan masih metode ceramah serta fasilitas yang masih kurang memadai.
