Abstract

Mata pelajaran matematika sampai sekarang ini masih menjadi momok bagi banyak siswa. Berdasarkan hasil observasi dan wawancara di sekolah dasar, ternyata masih saja hasil belajar matematika rendah hal ini kemungkinan terjadi dikarenakan banyak faktor salah satunya materi yang sulit ataupun dalam proses pembelajaran matematika karena konsep matematika adalah konsep yang mempunyai tingkat abstraksi yang cukup tinggi. Konsep matematika adalah konsep dari dinamika kehidupan yang disimbolkan dengan bahasa matematis dan diselesaikan menggunakan logika matematika yang terkadang begitu abstrak, dengan demikian peneliti tertarik untuk mengembangkan desain pembelajaran pembelajaran berbasis domain kognitif dengan pendekatan kontekstual agar konsep matematika dapat disampaikan lebih real. Berdasarkan hasil wawancara dan observasi dengan para pendidik di SD Negeri 7 Kelapa banyak pendidik yang kesulitan dalam menyampaikan konsep matematika. Untuk itu peneliti menawarkan solusi untuk merancang desain pembelajaran berbasis domain kognitif dengan pendekatan kontekstual. Penelitian ini merupakan penelitian pengembangan dengan menggunakan pendekatan ADDIE yaitu Analisys, Design, Depelopment, Implementation dan Evaluation. Subjek penelitian yaitu Guru dan siswa Kelas 4 Sekolah Dasar. Teknik Pengumpulan data menggunakan observasi, wawancara dan Angket. Penelitian ini menghasilkan desain pembelajaran berbasis domain kognitif yang sangat layak dengan persentase dari persentase respon guru sebesar 80,41% dan respon siswa sebesar 80, 59%.

Abstract

Tujuan dari penelitian ini adalah untuk: (1) menghitung kompetensi guru Matematika tingkat SMP tahun 2015 di Bangka Tengah, (2) menghitung rata-rata nilai UN Matematika SMP tahun 2017, (3) menentukan korelasi antara hasil UKG guru Matematika terhadap hasil belajar Matematika siswa SMP pada UN tahun 2017. Metode yang digunakan  adalah deskriprif kuantitatif. Subjek penelitian adalah guru dan siswa tingkat SMP. Waktu penelitian dilakukan di tahun 2019 selama 2 bulan yang berlokasi di Dinas Pendidikan Bangka dan beberapa SMP di Bangka Tengah.  Teknik pengumpulan data yang digunakan yaitu wawancara, dan studi pustaka. Adapun hasil yang diperoleh yaitu rata-rata UKG guru ada pada kategori cukup yaitu pedagogik ada pada kategori tinggi dengan skor rata-rata  66,29 dan profesional ada pada kategori cukup dengan  rata-rata 64,04. Untuk hasil ujian nasional  kabupaten Bangka Tengah siswa SMP pada tahun 2017 diperoleh rata-rata  64,19. Hasil penelitian menunjukkan diperoleh  nilai korelasi adalah 0,306. Nilai ini dapat diinterpretasikan bahwa hubungan kedua variabel penelitian lemah, selanjutnya diperoleh R Square atau koefisien determinasi (KD) sebesar  9,4 %  yang dapat ditafsirkan bahwa hasil UKG di Kabupaten Bangka Tengah  memiliki pengaruh kontribusi sebesar 9,4 % terhadap nilai UN siswa dan 90,6% lainnya dipengaruhi oleh faktor-faktor lain, diantaranya minat, bakat kecerdasan intelektual, kecemasan, kesiapan mental dalam diri siswa. AbstractIn this study, we want to see (1) the results of the mathematics teacher competency test in Central Bangka on the results of students' national exams in junior high school on mathematics subjects; (2) calculating the average value of the 2017 SMP Mathematics National Examination; (3) determining the correlation between the results of the UKG Mathematics teacher and the mathematics learning outcomes of junior high school students at the 2017 National Exam. The method used is quantitative descriptive. Research subjects were teachers and junior high school students. When the research was conducted in 2019 for 2 months located in the Bangka Education Office and several junior high schools in Central Bangka. Data collection techniques used were interviews, and literature study. As for the results obtained, the average UKG of teachers is in the sufficient category, namely pedagogics in the high category with an average score of 66.29, and professionals in the moderate category with an average of 64.04. For the results of the Central Bangka district national examination, junior high school students in 2017 obtained an average of 64.19. The results showed the correlation value obtained was 0.306. This value can be interpreted that the relationship between the two research variables is weak, then obtained R Square or a coefficient of determination (KD) of 9.4% which can be interpreted that the UKG results in Central Bangka Regency have a 9.4% contribution effect on students' UN scores and 90 Another 6% is influenced by other factors, including interest, intellectual intelligence, anxiety, mental readiness in students

Abstract

This community service is in the form of a workshop on preparing proposals, implementing, and writing reports on the results of Classroom Action Research (CAR) for SPM and MTs mathematics teachers in Tempilang District, West Bangka Regency. The background of this activity is the mandate of RI Law Number 20 of 2003 concerning National Education System which states that teachers must be professional and increase their capacity. One of them is through PTK. When going up to rank, teachers must make a CAR. Then PTK can improve the quality of learning in the classroom. However, not all teachers were able to compile proposals, implement, write CAR reports properly. So that this activity is held with the aim that teachers can improve the quality of learning in the classroom and can improve their professionalism through CAR. The workshop method with three activities, namely the initial activities include: an explanation of the theory of CAR and the importance of CAR. Practical activities include; find the background and title of the CAR, present it, and discuss the results of the presentation. Assistance activities include: assisting during the implementation of CAR, discussing problems that occur in the field, guiding the writing of CAR results. The workshop was held for two days and mentoring for two months. The results obtained are increasing teacher capacity in preparing proposals, implementing, and writing CAR reports. This can be seen from all the teachers writing down the background of the problem and the title of the CAR, half of the participants did the CAR, and only two participants collected the CAR report. Pengabdian kepada masyarakat ini berupa workshop penyusunan proposal, pelaksanaan, dan penulisan laporan hasil Penelitian Tindakan Kelas (PTK) bagi guru matematika SPM dan MTs di Kecamatan Tempilang Kabupaten Bangka Barat. Adapun latar belakang kegiatan ini adalah amanah Undang-undang RI Nomor 20 tahun 2003 tentang Sisdiknas yang menyatakan bahwa guru harus profesional dan meningkatkan kapasitas dirinya. Salah satunya melalui PTK. Ketika akan naik pangkat pun guru wajib membuat PTK. Kemudian PTK dapat meningkatkan kualitas pembelajaran di kelas. Namun guru belum semuanya mampu untuk menyusun proposal, pelaksaaan, penulisan laporan PTK dengan baik. Sehingga diadakan kegiatan ini dengan tujuan agar guru dapat meningkatkan kualitas pembelajaran di kelas serta dapat meningkatkan profesionalistasnya melalui PTK. Adapun metode workshop dengan tiga kegiatan yaitu kegiatan awal meliputi: penjelasan mengenai teori PTK dan pentingnya PTK. Kegiatan praktik meliputi; mencari latar belakang dan judul PTK, mempresentasikannya, dan mendiskusikan hasil presentasi. Kegiatan pendampingan meliputi: mendampingi selama pelaksanaan PTK, mendiskusikan masalah yang terjadi dilapangan, membimbing penulisan hasil PTK. Workshop diadakan selama dua hari dan pendampingan selama dua bulan. Hasil yang diperoleh yaitu peningkatan kapasitas guru dalam menyusun proposal, melaksanakan, dan menuliskan laporan PTK. Hal tersebut dapat terlihat dari semua guru menuliskan latar belakang masalah dan judul PTK, setengah dari peserta melakukan PTK, dan hanya dua orang peserta yang mengumpulkan laporan hasil PTK.
