This study aims to know the effect of biology teaching materials based on local wisdom integrated character education through problem-based learning models on students' high order thinking skills. This study uses a quantitative approach and belongs to the type of quasi-experimental research. The research design is the one group’s pre-test-post-test design. The research sample consisted of 111 students from five schools in West Aceh. The data collection used a validation sheet of the lesson plan and high-level thinking test questions. Research data was analysed by statistical average values, normality, homogeneity, and paired sample t test. The research results indicated that the using of biology teaching materials based on local wisdom integrated with character education through problem based learning models has a very significant effect on students' high-level thinking (P=0.00). The instruction that used local wisdom, character education and PBL model have a positive role in the motivating of students, cooperation, discipline, fond of reading, student achievement, and problems solving in accordance with the expected learning outcomes.

Soal tes merupakan alat yang diperuntukkan untuk mengukur dan atau mengetahui keberhasilan proses pembelajaran. Soal yang baik akan menghasilkan hasil pengukuran yang tepat dan sebaliknya soal yang tidak baik akan menghasilkan hasil pengukuran yang kurang tepat dari tujuan yang telah ditentukan. Tujuan penelitian adalah untuk mengetahui tingkat kesukaran soal tes berpikir tingkat tinggi berbasis kearifan lokal pada materi keanekaragaman hayati. Penelitian ini menggunakan pendekatan kuantitatif dan sedangkan jenis penelitian adalah deskriptif. Populasi dalam penelitian ini adalah seluruh siswa kelas X dari 5 sekolah menengah atas di kabupaten Aceh Barat yang berjumlah 284 siswa. Sampel yang digunakan dalam penelitian sebanyak 111 yang berasal dari kelas X sains. Sampel ditentukan dengan menggunakan teknik pengambilan sampel random sampling. Instrumen yang digunakan adalah lembar tes pilihan ganda sebanyak 20 soal. Teknik analisis data yang digunakan adalah uji tingkat kesukaran soal. Setelah dilakukan analisis data, kemudian data di intepretasikan dalam bentuk kata-kata, yaitu sukar (P < 0,3), Sedang (0,3 ≤ p ≤ 0,7), dan mudah (P > 0,7). Hasil analisis data menunjukkan bahwa soal yang berkriteri sukar 5 soal, berkriteria sedang 10 soal, dan berkriteria mudah 5 soal dengan perbandingan persentase 25:50:25. Hasil penelitian juga menunjukkan bahwa level taksonomi bloom tidak berpengaruh terhadap kategori soal tersebut mudah, sukar, dan sedang

The success of the learning process affects the skills possessed by the teacher such as pedagogic skills, content skills, and knowledge skills.This study aims to determine the PCK owned by teachers and its effects on student learning outcomes. This study uses a qualitative approach with type of descriptive research. The population in this study consisted of 12 teachers and 228 grade X students from 5 high schools in West Aceh. The research sample consisted of 5 teachers and 111 students of class X science. The research instrument used in this study was the PCK observation sheet of the teacher learning process and student learning outcomes tests. Data from observations and results of student learning tests were analyzed using the average value test formula. The results of this study indicate that (1) PCK of teachers is in the bad category totaling two, good enough totaling one, good totaling one, and very good totaling one, and (2) However, when comparing the results of PCK teacher observations with student learning outcomes it is known that the higher the PCK knowledge of the teacher, the higher the student learning outcomes.
