This research is a qualitative research aimed to disclose math problem-solving ability based on Polya steps on SPLDV’s material in term of student personalities melancholy (ME). Instruments used for this research are : 1) personality test is used to categorize the students based on their personality, 2) math problem-solving test is used to show students' ability in solving mathematical problems based on Polya steps, and 3) guided interview is contained guidelines aim to clarify answers and trace the process of students’ thought in depth. Data are collected by test and interview and analyzed by using Miles and Huberman’s data analysis. The research processes are: (a) formulated the indicators based on math problem-solving on Polya steps (b) formulated a valid and reliable instrument (personality test, math problem-solving task and guided interview) (c) collected the subject by providing personality type, (d) collected data to show the description of math problem-solving is done by the students, (e) did time triangulation to get valid data, (f) performed data analysis problem-solving based on personality types, (g) conducted a discussion of the results of analysis, (h) drew conclusions of the research. The results showed the subject of melancholy did the Polya steps in problem-solving, which are (1) understand the problem (2) plan a settlement (3) settle a plan (4) check back.
This research is qualitative research with the aim of (1) to find out the description of mathematical communication skills of male and female students in solving mathematical problem-solving questions, (2) to find out different information about mathematical communication descriptions in solving problem-solving problems in terms of gender. The subjects of this study were two class VII students of SMP Negeri 2 Labakkang, namely one male and one female student who had the highest problem-solving test scores. The procedure of data collection is done by observation, tests of problem-solving and interviews. The research instrument was used in the form of observation sheets, tests of problem solving, interview guidelines. Data analysis techniques are carried out by testing credibility, transferability, dependability, and conformability. The results showed that the mathematical communication skills of male gender subjects were lower than those of female gender subjects. The location of differences in mathematical communication skills between male and female gender is that the indicators write answers according to the purpose of the problem and make conclusions in writing using their own language.
Penelitian ini adalah penelitian deskriptif kualitatif yaitu mendeskripsikan tingkat pemikiran siswa berdasarkan teori Van Hiele pada materi dimensi tiga ditinjau dari gaya kognitif Field Dependent (FD). Tingkat berpikir yang dimaksud adalah tingkat berpikir menurut teori Van Hiele yang terdiri dari lima tahapan, yaitu tahap 0 (visualisasi), tahap 1 (analisis), tahap 2 (deduksi informal), tahap 3 (deduksi), dan tahap 4 (rigor). Subjek penelitian ini adalah siswa kelas XII MIPA1 SMAN 1 Pangkajene yang terdiri 2 orang siswa yang mewakili kelompok Field Dependent (FD). Instrumen dalam penelitian ini adalah GEFT (Group Embedded Figure Test)untuk mengukur gaya kognitif siswa Field Dependent (FD), tes Geometri untuk mengetahui tingkat berpikir siswa ditinjau dari gaya kognitifnyadan wawancara berbasis tesyang bertujuan menelusuri danmengklarifikasi jawaban siswa secara mendalam. Data dikumpulkan melalui tes dan wawancara dan dianalisis dengan menggunakan model analisis data Miles dan Huberman. Hasil penelitian menunjukkan bahwa: subjek pertama dengan gaya kognitif Dependent Dependent (FD) berada pada tingkat analisis sedangkan subjek keduadengan gaya kognitif Dependent Dependent (FD) berada pada tingkat visualisasi. Kata Kunci : Tingkat berpikir teori van Hiele, gaya kognitif Field Dependent (FD)
Penelitian ini merupakan penelitian kualitatif yang bertujuan untuk menggambarkan kemampuan pemecahan masalah matematika berdasarkan langkah polya pada materi SPLDV ditinjau dari kepribadian siswa tipe phlegmatis (PE). Instrumen dalam penelitian ini adalah tes kepribadian, tes pemecahan masalah matematika serta pedoman wawancara. Tes kepribadian digunakan untuk mengelompokkan siswa berdasarkan kepribadiannya, tes pemecahan masalah akan digunakan untuk menunjukkan kemampuan siswa dalam memecahkan masalah matematis berdasarkan langkah polya, dan pedoman wawancara berisi sejumlah panduan yang bertujuan mengklarifikasi jawaban dan menelusuri proses berpikir siswa secara mendalam. Data dikumpulkan melalui tes dan wawancara dan dianalisis dengan menggunakan model analisis data Miles dan Huberman. Proses penelitian mengikuti tahap-tahap: (a)merumuskan indikator pemecahan masalah matematika berdasarkan langkah polya, (b)merumuskan instrumen pendukung (tes penggolongan tipe kepribadian, tugas pemecahan masalah matematika dan pedoman wawancara) yang valid dan reliabel, (c)melakukan pengambilan subjek penelitian dengan memberikan penggolongan tipe kepribadian, (d)melakukan pengambilan data untuk mengungkap deskripsi pemecahan masalah matematika yang dilakukan oleh siswa, (e)melakukan triangulasi waktu untuk mendapatkan data yang valid, (f)melakukan analisis data pemecahan masalah berdasarkan tipe kepribadian, (g)melakukan pembahasan hasil analisis, (h)melakukan penarikan kesimpulan hasil penelitian. Hasil penelitian menunjukkan bahwa subjek phlegmatis melakukan pemecahan masalah mengikuti langkah-langkah Polya yakni: (1)memahami masalah, (2)merencanakan penyelesaian, (3)melakukan rencana penyelesaian, (4)memeriksa kembali.
