Berdasarkan hasil wawancara terhadap guru biologi di kelas X MAN 2 Pontianak pada tahun ajaran 2014/2015, diketahui adanya permasalahan kesulitan belajar siswa pada materi invertebrata. Tujuan dari penelitian ini adalah untuk menganalisis kesulitan belajar siswa dalam memahami materi invertebrata.Metode yang digunakan adalah metode deskriptif.Subjek penelitian adalah siswa kelas XI IPA 1 berjumlah 3 3 siswa.Subjek penelitian ditentukan berdasarkan teknik purposive sampling.Kesulitan belajar dianalisis dengan teknik pengukuran, wawancara dan komunikasi tidak langsung.Instrumen yang digunakan adalah tes pilihan ganda, pedoman wawancara dan angket tertutup bentuk check list berskala Likert. Hasil analisis data tes menunjukkan persentase kesulitan belajar siswa sebesar 39,92%. Hasil wawancara menunjukkan jenis kesulitan belajar siswa antara lain kesulitan dalam memahami penamaan ilmiah (59,74%), kesulitan dalam memahami konsep (40,15%) dan kesulitan dalam memahami istilah (26,66%). Hasil angket menunjukkan faktor internal yang mempengaruhi kesulitan belajar siswa meliputi aspek minat (67,14%), motivasi (63,36%), kesehatan (70,08%) dan intelegensi (53,23%). Faktor eksternal yang mempengaruhi kesulitan belajar siswa meliputi aspek keluarga (72,07%) dan sekolah (67,24%), serta guru (54,74%). Namun, faktor-faktor penyebab kesulitan belajar siswa yang berpengaruh cukup adalah faktor internal dari aspek intelegensi dengan indikator pemahaman dan kemampuan siswa dalam menyelesaikan soal materi invertebrata, serta faktor eksternal dari aspek guru dengan indikator penggunaan metode dan media pembelajaran.Kata Kunci: Kesulitan belajar, materi invertebrata
The problem of implementing Islamic values in the learning process is one of the concerns in Islamic-based schools, in particular, Rahmatan Lil’alamin Islamic Senior High School in Pontianak. This study aimed to develop learning media based on the Quran verses in the human reproductive system using Macromedia flash software. This research and development used three phases of the 4D model developed by Thiagarajan, namely define, design, and development. The development results were validated by expert appraisal consisted of instructional review (appropriateness, effectiveness, feasibility) and technical review (media and language). Instruments used in this study were interview guide sheet (define phase), validation sheets, student response questionnaires, and post-test for product trial (development phase). Product trials were carried out by testing large groups consisted of 64 students majoring in social science at Rahmatan Lil’alamin Islamic Senior High School. The expert appraisal results showed that media reached “very valid” criteria with the validation scores 83.33 (instructional review), 80.42 (media), and 85.00 (language). Therefore, the flash media of Quranic-based human reproductive system material is potential to be used as media in teaching Islamic values integrated within the learning process.
Higher-Order Thinking Skills (HOTS) is one of the most important aspects to increase the quality of education. However, HOTS in SMA Muhammadiyah 1 Pontianak is considered still not appearing. This can be seen from the practice questions given by the teacher still using the verb C1-C3. Besides that based on the result of interviews with students, the learning pattern applied by biology teachers who still conventional method makes students bored and less motivated to study biology. The use of a joyful learning model is expected to help students to improve their HOTS and motivation in learning. This study aimed to determine the effect of a joyful learning model on students’ HOTS and their learning motivation. This quasi-experimental research involved 30 students of X MIA 1 and X MIA 2 as the sample. Data were collected through test and questionnaires which was analyzed using effect size. The results obtained from the test show that joyful learning model could improvements in the both students’ HOTS and learning motivation, indicated by the value of effect size HOTS obtained at 0,31 which is included in the medium category, and students’ motivation in learning with the effect size value at 1,15 which is categorized as very high. Thus, joyful learning could improve HOTS and learning motivation in senior high school.
Pemahaman konsep sangat penting dalam pembelajaran biologi. Akan tetapi, siswa seringkali memahami konsep yang salah sehingga menyebabkan terhambatnya proses penerimaan pengetahuan baru dalam diri siswa. Tujuan penelitian ini adalah untuk menganalisis miskonsepsi siswapada submateri sistem saraf. Metode yang digunakan adalah metode deskriptif. Subjek penelitian adalah seluruh siswa kelas XI IPA SMA Negeri 1 Selimbau tahun ajaran 2014/2015 yang berjumlah 29 orang. Subjek penelitian ditentukan berdasarkan teknik sampling jenuh. Miskonsepsi dianalisis dengan menggunakan teknik Certainty Of Response Index (CRI). Wawancara dilakukan untuk mendeskripsikan miskonsepsi siswa dan faktor penyebab miskonsepsi pada submateri sistem saraf. Hasil analisis data dengan CRImenunjukkan dari29 orang siswa,24,71%termasuk ke dalam kategori tahu konsep, 38,39% mengalami miskonsepsi, dan 36,9% tidak tahu konsep. Hasil wawancara menunjukkansiswa mengalami miskonsepsipada deskripsineuron, struktur dendrit dan akson, fungsi neuron sensorik dengan motorik, istilah lain dari neuron aferen, eferen, dan interneuron, penjalaran impuls pada gerak sadar, dan penjalaran impuls yang relatif cepat pada gerak sadar. Faktor penyebab miskonsepsi pada siswa adalah cakupan materi yang luas, rumit, banyak menggunakan istilah-istilah asing,pengetahuan dari pengalaman siswa, kemampuan dan metode pembelajaran yang diterapkan oleh guru, serta pemakaian buku teks yang kurang maksimal.Kata kunci: Certainty Of Response Index (CRI), Miskonsepsi, Submateri sistem saraf
