The purpose of this study is to determine the level of mathematical literacy on students with high ability in mathematics problems solving in VIII grade of Junior High School (SMP). The study was conducted at SMP Negeri 3 Purwodadi in 2018/2019 academic year. This research is a descriptive qualitative research. Data collection was done by tests, interviews, and documentation. The research subjects were chosen by three students, all of whom are students with high literacy mathematical abilities. The results showed that the mathematical literacy process of students at the stage of formulating mathematical problems was identifying the mathematical aspects of a problem context in real life and identifying known variables; determine mathematical models and simplify problems; and determine aspects of mathematical concepts, facts or procedures of a problem.Abstrak:Tujuan penelitian ini adalah mengetahui tingkat literasi matematika siswa kemampuan tinggi dalam memecahkan masalah matematika kelas VIII SMP. Penelitian dilakukan di SMP Negeri 3 Purwodadi pada tahun ajaran 2018--2019. Penelitian ini merupakan penelitian kualitatif deskriptif. Pengumpulan data dilakukan dengan tes, wawancara, dan dokumentasi. Subjek penelitian dipilih tiga siswa, yang ketiganya merupakan siswa dengan literasi matematika kemampuan tinggi. Hasil penelitian menunjukkan bahwa proses literasi matematika siswa pada tahap merumuskan masalah secara matematis yaitu mengidentifikasi aspek matematika dari suatu konteks masalah di kehidupan nyata dan mengidentifikasi variabel yang diketahui; menentukan model matematika dan menyederhanakan masalah; serta menentukan aspek konsep matematika, fakta, atau prosedur dari suatu masalah.

Physics learning will give optimal learning outcomes if the students can buildknowledge and find the answer of a problem through the learning process which has beendone. Separately, some studies show that students lack of creative thinking ability andscientific works. Therefore, it needs project based learning model which can sharpen thestudents creative thinking ability to learn Physics.This experimental study aimed to know theeffects of Project Based Learning model through the method of laboratory working on thecreative thinking ability on the material of harmonic vibration at grade XI MIA of SMAN 1Comal. The samples of this study were Class XI MIA 2 as the experimental class and Class XIMIA 3 as the control class. The techniques used to gather the data in this study weredocumentation, observation, and tests.Based on the analysis of the hypotheses using one-tailed t-test with right side, the results showed that the was 2,99 and the was 1,67. Itcould be seen that the was higher than the so that the Ha was acceptedisaccepted. Meanwhile, from the gain test, it was obtained that the of experimental class was0.710 with high category and the of control class was 0.611 with medium category.The learning using Project Based Learning model through the method of laboratory working on thematerial of Harmonic Vibration at Grade XI MIA of SMAN 1 Comal gives effects on thecreative thinking ability and can develop the students’ creative thinking ability. Keywords: Creative Thinking Ability, Practicum Methods, Project Based Learning.
