Abstract

The purpose of this research was described critical thinking stage of students grade VIII in setting PBL and scaffolding to solve mathematics problems. Critical thinking stage consists of clarification, assesment, inference, and strategy/tactics. The subject were teo students in the level of capacity to think critical (uncritical, less critical, quite critical, and critical). So that this research subject was 8 students in VIII A One State Junior High School of Temanggung. The result showed a description (1) critical thinking stage of students in setting PBL, in clarification the higher level of capacity to think critical students, students can identification information from question fully, can identificatio problem became detailed, and can explored the relationship among the information; (2) a strategy of scaffolding were given by critical thinking stage and TKBK, in assesment, scaffolding had given was given hint/key classically; and (3) transformation characteristic of the critical thinking stage of students after given scaffolding, it because of habituation in setting PBL and scaffolding.

Abstract

Berpikir aljabar merupakan representasi dari aktivitas maupun kemampuan dalam mempelajari aljabar sekolah. Tujuan penelitian ini adalah untuk mengetahui kemampuan berpikir aljabar siswa SMP Kelas VIII. Metode penelitian yang digunakan adalah dengan pendekatan deskriptif kualitatif. Penelitian ini dilakukan dengan memberikan tes kemampuan berpikir aljabar pada siswa. Selanjutnya berdasarkan hasil tes, siswa dikelompokkan berdasarkan kemampuan berpikir aljabar mereka yang terdiri dari kelompok tingkat tinggi, kelompok tingkat sedang, dan kelompok tingkat rendah. Dari masing-masing kelompok tersebut dipilih dua subjek sebagai perwakilan untuk diwawancara lebih lanjut terkait kemampuan berpikir aljabar mereka. Hasil analisis dari penelitian ini menunjukkan bahwa kemampuan generasional, transformasional, dan level-meta global sudah terlihat pada sebagian siswa kelas VIII. Siswa yang termasuk dalam kelompok tingkat tinggi mempunyai kemampuan generasional, transformasional, dan level-meta global yang cenderung tinggi. Sedangkan siswa dalam kelompok rendah mempunyai kemampuan transformasional yang cenderung rendah, kemampuan generasional yang rendah sampai sedang, dan kemampuan level-meta global yang rendah sampai sedang. Algebraic thinking is a representation of activities and abilities to learn school algebraic. The aim of this research was to determine the ability of eighth grade junior high school students in algebraic thinking. The method used in this research was the qualitative descriptive approach. This research was conducted with giving a test of algebraic thinking skills to the students. Furthermore, based on test results, students are grouped according to their algebraic thinking skills which consists of a high­level group, moderate­level group and low­level group. From each group, two subjects were selected to be interviewed more related their algebraic thinking skills, as a representative for their each group. Analytical results from this research indicated that the ability in generational, transformational, and global meta­level activities is already visible in some eighth grade students. Students were included in the high­level group tend to have high skill in generational, transformational, and global meta­level activities. While students were included in the low­level group tend to have low skill in transformational ability, low to medium skill in generational ability, and low to medium skill in global meta­level ability.

Abstract

The accurate understanding of critical thinking and mathematical creativity in solving the current problem is still difficult to standardize. These two thinking skills are indispensable to anyone who is studying mathematics, especially for Undergraduate Mathematics students who are studying Linear Algebra. However, the difficulties in critical thinking discourage students to think creatively and mathematically. In linear algebraic subject matter, many problems require critical reasoning. It goes without saying that the difficulties in various reasoning aspects critically cause other difficulties in developing creative thinking aspects. Further, mathematical critical thinking skills in solving problems require a background in understanding the concepts related to the problem faced. In addition, the failure to understand and connect between concepts in solving linear algebra problems makes it worst and difficult to critically and creatively think.

Abstract

This research aimed to describe the ability to interpret the information in the student's algebraic critical thinking. The type of research is a mixture of quantitative and qualitative. Methods of data collection are tests and interviews. The results of the algebraic critical thinking test referring to Watson-Glaser were analyzed descriptively quantitatively, then 6 subjects were selected each of 2 subjects including the upper, middle, and lower groups for interviews. Triangulation was carried out using 2 different subjects for each level and comparison of test results and interview results. The results of this research indicate the average Algebraic Critical Thinking ability of 31 students was 50.14 and the standard deviation was 9.09, with the lowest average inference ability was 32.64, and the highest average argument was 62.63; the correlation coefficient of algebraic critical thinking skills with indicators of inference, recognition assumptions, deductions, interpretations, evaluations of arguments, each of which amounted to 0.3264, 0.5126, 0.5417, 0.4602, 0.6263; and that the upper group subjects were able to interpret information in the medium category, the middle group subjects were able to interpret information in the medium category, and the lower group subjects were able to interpret the information in the low category.
