SAMAHAH, NAILIS
Penelitian ini bertujuan untuk mengetahui respon siswa terhadap lembar kegiatan siswa yang dikembangkan dan mengetahui keterampilan berpikir kritis siswa setelah pembelajaran menggunakan lembar kegiatan siswa yang dikembangkan. Keterampilan berpikir kritis perlu dilatihkan secara aktif dan berkelanjutan. Pengembangan lembar kegiatan siswa sebagaimana bahan ajar lainnya diperlukan untuk menyesuaikan dengan karakteristik siswa dan sasaran yang dituju pada akhir pembelajaran. Pengembangan LKS yang bertujuan untuk melatihkan keterampilan berpikir kritis memerlukan pendekatan yang sesuai. Salah satu pendekatan yang sesuai dalam memecahkan masalah daya pikir kritis adalah melalui pendekatan kontekstual. Penelitian ini menggunakan desain penelitian R&D, namun terbatas pada tahap uji coba terbatas.

Berdasarkan hasil uji konsepsi 1 diperoleh persentase tahu konsep (TK), tidak tahu konsep (TTK), dan miskonsepsi (MK) berturut-turut sebesar 39%, 9%, dan 53%.Uji konsepsi 2 dilakukan setelah pembelajaran remedial untuk mengetahui konsepsi akhir siswa. Pada uji konsepsi 2 persentase tahu konsep (TK), tidak tahu konsep (TTK), miskonsepsi (MK) berturut-turut sebesar 69%, 8%, dan 23%. Berdasarkan hasil analisis uji konsepsi 1 dan 2 diketahui persentase pergeseran miskonsepsi siswa menjadi tahu konsep sebesar 71%.

POLA PERGESERAN KONSEPSI SISWA BERBASIS MODEL MENTAL ATRIBUT PEMAHAMAN WACANA DENGAN STRATEGI MEMBACA RECIPROCAL TEACHING PADA KONSEP IKATAN KIMIA (THE PATTERNS OF STUDENT’S CONCEPTION BASED ON COMPREHENSION TEXT MENTAL MODEL WITH RECIPROCAL TEACHING READING STRATEGIES ON THE CONCEPT OF CHEMICAL BONDING)
DILLAH, ROCHMAH
Tujuan dari penelitian ini adalah mengetahui pola pergeseran konsepsi siswa berbasis model mental atribut pemahaman wacana pada konsep ikatan kimia setelah proses remediasi menggunakan strategi membaca reciprocal teaching. Rancangan penelitian yang digunakan adalah one group pretest-posttest design. Status miskonsepsi ditetapkan menggunakan soal konsep yang disertai certainty of response index (CRI). Penetapan tingkat pemahaman wacana rendah menggunakan tes model mental atribut pemahaman wacana. Analisis data menggunakan Wilcoxon’s signed rank test. Hasil penelitian menunjukkan konsepsi siswa sebelum remediasi adalah tahu konsep sebesar 45,10%, tidak tahu konsep sebesar 7,06%, dan miskonsepsi sebesar 47,84%. Setelah remediasi, konsepsi dari tujuh belas siswa mengalami pergeseran menjadi tahu konsep sebesar 71,77%, tidak tahu konsep sebesar 1,96%, dan miskonsepsi sebesar 26,27%. Berdasarkan hasil Wilcoxon’s signed rank test, pembelajaran remedial menggunakan strategi membaca reciprocal teaching dapat merubah konsepsi siswa berpemahaman wacana rendah (menaikkan jumlah siswa tahu konsep dan menurunkan jumlah siswa yang berada pada pemahaman tidak tahu konsep dan miskonsepsi) secara signifikan pada konsep ikatan kimia.
Kata Kunci: remediasi, pola pergeseran konsepsi, pemahaman wacana.
The main of this research is to know the patterns of student’s conception based on comprehension text mental model on the concept of chemical bonding after remediation with reciprocal teaching reading strategies. Research design was used one group pretest-posttest design. Student’s conception status defined use concept’s question is accompanied certainty of response index (CRI). Student’s low comprehension text was determinated by using an mental model of comprehension text’s test. Data analysis used in this research was Wilcoxon’s signed rank test. The results showed that student’s conception before remediation are know concept by 45,10%, not know the concept by 7,06%, and misconception by 47,84%. After remediation, student’s conception shifted into know concept by 71,77%, not know the concept by 1,96%, and misconception by 26,27%. Based on the results of the Wilcoxon’s signed rank test, remediation with reciprocal teaching reading strategies can shift student’s conception who have low comprehension text (increasing student’s know concept and decreasing student’s not know concept and misconception) significantly on the concept of chemical bonding.

MAULANA PUTERA HIDAYAT, CINDY
Abstrak
Penelitian ini bertujuan untuk meremediasi siswa yang memiliki beban miskonsepsi tinggi pada ikatan kimia dan memiliki tingkat persepsi rendah menggunakan pembelajaran remedial strategi analogi. Sasaran penelitian adalah 17 siswa yang memiliki beban miskonsepsi tinggi dan persepsi rendah pada kelas X MIA 1 hingga X MIA 6 di SMAN 17 Surabaya. Beban miskonsepsi tinggi adalah jumlah miskonsepsi dibagi jumlah soal di atas rata-rata miskonsepsi siswa di semua kelas X MIA yang terdiri atas enam kelas. Tingkat persepsi rendah merupakan siswa yang memiliki level 3 dan 4 berdasarkan data uji persepsi. Rancangan penelitian adalah one group pretest-posttest design. Pembelajaran remedial dengan strategi analogi telah berhasil menurunkan beban miskonsepsi secara signifikan sebesar 75%. Menurut hasil uji wilcoxon, strategi analogi dapat menurunkan beban miskonsepsi secara signifikan. Berdasarkan hasil penelitian dapat disimpulkan bahwa strategi analogi efektif dalam mereduksi miskonsepsi siswa.
Kata Kunci: pembelajaran remedial, miskonsepsi, persepsi, konsep ikatan kimia, strategi analogi.
