Abstract

HIGH SCHOOL CHEMISTRY TEACHERS' UNDERSTANDING OF HIGHER-ORDER THINKING SKILLS AND ITS IMPLEMENTATIONAbstractTeachers play an essential role in attempts to develop students' higher-order thinking skills through the implementation of classroom assessments. This study explores chemistry teachers' understanding of higher-order thinking skills (HOTS) assessments, how they implement the assessments, and what obstacles they face. This study employed a qualitative approach that involved 12 high-school chemistry teachers in South Jakarta. Data collection was conducted in August and September 2019 through semi-structured interviews. The findings of this study show that the chemistry teachers have a different understanding of higher-order thinking assessments.  The majority of teachers associate HOTS with the three highest levels of the cognitive dimension of Revision of  Bloom's taxonomy, critical thinking,  and problem-solving. The levels of implementation of HOTS assessments among teachers vary. Among obstacles faced by the teachers are the lack of teachers' knowledge and experience in applying HOTS assessments, variability in students' cognitive abilities, the scarcity of learning facilities, and the lack of guidance and training about HOTS assessments in chemistry. AbstrakGuru memegang peranan penting dalam upaya mengembangkan kemampuan siswa dalam berpikir tingkat tinggi melalui penerapan penilaian kelas.Penelitian ini menggali pemahaman guru kimia tentang penilaian kemampuan berpikir tinggi tinggi (HOTS), penerapannya, dan hambatan-hambatan yang dihadapi. Penelitian ini menggunakan pendekatan kualitatif yang melibatkan 12 orang guru kimia SMA di Jakarta Selatan. Pengumpulan data dilakukan pada bulan Agustus dan September 2019 melalui wawancara semi-terstruktur. Temuan dalam penelitian ini menunjukkan bahwa para guru kimia memiliki pemahaman yang beragam tentang penilaian HOTS. Mayoritas guru mengaitkan penilaian HOTS dengan tiga jenjang tertinggi  dimensi kognitif pada taksonomi Bloom yang telah direvisi, berpikir kritis, dan penyelesaian masalah. Tingkat penerapan penilaian HOTS di kalangan guru bervariasi. Hambatan yang dihadapi para guru Kimia SMA dalam melaksanakan penilaian HOTS, antara lain  keterbatasan pengetahuan dan pengalaman  guru dalam menerapkan penilaian HOTS,  kemampuan kognitif siswa yang bervariasi, keterbatasan fasilitas pembelajaran, dan kurangnya panduan dan pelatihan tentang penilaian HOTS untuk mata pelajaran kimia.

Abstract

ANALISIS PENALARAN MAHASISWA PENDIDIKAN BIOLOGI PADA MATA KULIAH TAKSONOMI TUMBUHAN DENGAN MODEL RASCHAbstractThe reasoning is the stage of thinking that tries to connect facts or evidence to reach conclusions. The reasoning includes thinking and reasoning skills that support the formation and modification of concepts. The complexity of learning stages and reasoning gives results in inequality or low levels of reasoning owned by students. This study aimed to analyze the reasoning of students in the Plant Taxonomy course. This research used a descriptive quantitative design. This research used a test instrument administered on 36 students of Biology Education of UIN Raden Fatah Palembang with data collected using questions with indicators based on Toulmin's assessment (2003). The data analysis was conducted by analyzing the level of individual ability (person measure) to determine students' reasoning ability. The data analysis showed that one student had a logit person score of +3.05, namely student number 02, with a high reasoning category. There were twenty-four students, with a medium reasoning category. Two students have the lowest logit person score, namely students 08 and 14, with a logit person score of -0.49. The results indicated that generally, students had difficulty finding plant taxonomy concepts; therefore, thinking needed to be taught more in-depth, so students could manage the information received and conduct a good reasoning analysis in problem-solving.AbstrakPenalaran merupakan tahap berpikir yang mencoba menghubungkan fakta atau evidensi untuk mencapai kesimpulan. Penalaran mencakup keterampilan berpikir dan bernalar yang mendukung pembentukan dan modifikasi konsep. Kompleksnya tahapan belajar hingga pada tahap penalaran, mengakibatkan adanya ketidakmerataan atau rendahnya tingkat penalaran yang dimiliki oleh mahasiswa. Penelitian ini bertujuan untuk menganalisis penalaran mahasiswa pada Mata kuliah Taksonomi Tumbuhan. Jenis penelitian adalah deskriptif kuantitatif.  Penelitian menggunakan instrumen tes yang dilaksanakan pada 36 mahasiswa Pendidikan Biologi UIN Raden Fatah Palembang. Data dikumpulkan menggunakan soal dengan indikator berdasarkan asesmen Toulmin (2003). Analisis data dengan menganalisis tingkat abilitas individu (person measure) untuk melihat kemampuan penalaran mahasiswa. Hasil analisis menunjukkan bahwa terdapat satu mahasiswa yang memiliki nilai logit person +3,05 yaitu mahasiswa nomor 02, dengan kategori penalaran tinggi. Terdapat dua puluh empat mahasiswa, dengan kategori penalaran sedang. Terdapat dua mahasiswa yang memiliki nilai logit person paling rendah, yaitu mahasiswa 08 dan 14 dengan nilai logit person -0,49. Hasil penelitian menunjukkan bahwa, secara umum mahasiswa banyak mengalami kesulitan dalam menemukan konsep taksonomi tumbuhan sehingga perlu lebih dalam mengajarkan cara berpikir mahasiswa, sehingga mahasiswa dapat mengelola informasi yang diterima dan melakukan analisis penalaran yang baik dalam memecahkan masalah.

Abstract

EXPLORATION OF FISHERMAN CHILDREN'S DAILY LIFE ACTIVITIES AT LOBUK VILLAGE TO SUPPORT CONTEXTUAL SCIENCE LEARNINGAbstractThe daily activities of fishermen's children can be used as a material context in applying contextual science learning, as emphasized by K13. In fact, learning science in coastal schools is not yet contextual to the daily activities of fishermen's children. This study aims to provide a description of the daily activities of fishermen's children in Lobuk Village, and a description of the relationship between these activities and science learning materials for SMP/MTs. This type of research is a descriptive qualitative case study method. The primary data sources were fishermen children aged SMP/MTs and their parents. Data collection techniques in the form of interviews, observation, and documentation. The results showed that fishermen's children's morning activities were helping with homework, preparing for school, then leaving for school. The daytime activity is helping the mother/aunt work in the drying process of the fish (a gherri jhuko'). The afternoon activity is looking for shells (arang-karang) during low tide, some of the shells are sold to earn pocket money or for parents, and some are used as salad. Nighttime activities are reciting/tarawih, tadarus, watching TV, then sleeping. The daily activities of fishermen children in their routine of helping to work a gherri jhuko’ and arang-karang in Lobuk Village are related to science learning materials for SMP/MTs, namely the classification of shells in Mollusca type invertebrates; the application of solid substance pressure to the knife for nyetak, mowang bunto ', and a gherri jhuko'. AbstrakAktivitas sehari-hari anak nelayan bisa digunakan sebagai konteks materi dalam menerapkan pembelajaran IPA kontekstual, sebagaimana penekanan K13. Faktanya, pembelajaran IPA di sekolah pesisir belum kontekstual terhadap aktivitas sehari-hari anak nelayan. Penelitian ini bertujuan untuk memberikan deskripsi aktivitas sehari-hari anak nelayan di Desa Lobuk, dan deskripsi keterkaitan aktivitas tersebut dengan materi pembelajaran IPA SMP/MTs. Jenis penelitian ini adalah deskriptif kualitatif dengan metode studi kasus. Sumber data primer dari anak-anak nelayan usia SMP/MTs beserta orang tua. Teknik pengumpulan data berupa wawancara, observasi, dan dokumentasi. Hasil penelitian menunjukkan aktivitas pagi hari anak nelayan adalah membantu pekerjaan rumah, menyiapkan diri ke sekolah, lalu berangkat sekolah. Aktivitas siang hari adalah membantu ibu/bibinya bekerja dalam proses pengeringan ikan (a gherri jhuko’). Aktivitas sore hari adalah mencari kerang (arang-karang) saat air laut surut, sebagian kerang dijual untuk menghasilkan uang jajan atau untuk orang tua, dan sebagian lagi dirujak. Aktivitas malam hari adalah mengaji/tarawih, tadarus, nonton TV, lalu tidur. Aktivitas sehari-hari anak nelayan dalam rutinitas membantu bekerja a gherri jhuko’ dan arang-karang di Desa Lobuk berkaitan dengan materi pembelajaran IPA SMP/MTs, yaitu pengklasifikasian kerang dalam avertebrata jenis Mollusca; penerapan tekanan zat padat pada pisau untuk nyetak, mowang bunto’, dan a gherri jhuko’.
