(12) bakat numerik, kecerdasan spasial dan kecerdasan logis matematis berkontribusi secara simultan dan signifikan terhadap prestasi belajar matematika sebesar 42,8%.Kata Kunci : bakat numerik, kecerdasan spasial, kecerdasan logis matematis dan prestasi belajar matematika The main purpose of this research was to find out the contribution numerical talent, spatial intelligence and logical-mathematical intelligence toward mathematical achievement. The population of this research was fifth grade of elementary school in buleleng regency as many as 83554 students. Slavin formula was used to determine the sample of this research, which altogether 100 students. The sample for every region was determined by proporsive random sampling technique. Data was collected by numerical talent test, spatial intelligence test and logical-mathematical intelligence test, especially for mathematical achievement data was collected by using the students' first semester score in the odd semester. Data was analyzed by path analysis. The result indicate that: (1) the students' numerical talent was classified very good level with an average score of 22,860. (2) the students' spatial intelligence was classified good level with an 22,390 average score of 22,390. (3) the students' logical-mathematical intelligence was classified good level with an average score of 22,350. (4) the students' mathematical achievement was classified good level with an average score of 71,970. (5) the contribution numerical talent toward logical-mathematical intelligence is 25,3%. (6) the contribution spatial intelligence toward logical-mathematical intelligence is 27,4%. (7) the direct contribution numerical talent toward mathematical achievement is 27,5% and indirect contribution is 7,0%, so the total contribution numerical talent toward mathematical achievement is 36,7%. (8) the direct contribution spatial intelligence toward mathematical achievement is 29,1% and the indirect contribution is 7,6%, so the total contribution spatial intelligence toward mathematical achievement is 36,7%. (9) the contribution logical-mathematical intelligence toward mathematical achievement is 27,7%. (10) numerical talent and logical-mathematical intelligence contributing simultaneously and significantly toward mathematical achievement by 36,7%. (11) spatial intelligence and logical-mathematical intelligence contributing simultaneously and significantly toward mathematical achievement by 37,2%. (12) numerical talent, spatial intelligence and logical-mathematical intelligence contributing simultaneously and significantly toward mathematical achievement by 42,8%.

Pengaruh Penerapan Strategi Pembelajaran Pemecahan Masalah Berbasis Masalah Matematika Otentik Terhadap Kemampuan Memecahkan Masalah Matematika Ditinjau Dari Kemampuan Berbahasa Indonesia Siswa Kelas VIII SMP Harapan Nusantara Denpasar

Eka Suryantari, I Gusti Agung (2013), “Pengaruh Penerapan Strategi Pembelajaran Pemecahan Masalah Berbasis Masalah Matematika Otentik Terhadap Kemampuan Pemecahan Masalah Matematika Ditinjau Dari Kemampuan Berbahasa Indonesia Siswa Kelas VIII SMP Harapan Nusantara Denpasar”. Penelitian ini bertujuan untuk mengetahui 1) pengaruh penerapan strategi pembelajaran pemecahan masalah berbasis masalah matematika otentik terhadap kemampuan pemecahan masalah matematika pada siswa dengan kemampuan berbahasa Indonesia tinggi, 2) pengaruh penerapan strategi pembelajaran pemecahan masalah berbasis masalah matematika otentik terhadap kemampuan pemecahan masalah matematika pada siswa dengan kemampuan berbahasa Indonesia rendah, 3) adanya interaksi antara strategi pembelajaran pemecahan masalah berbasis masalah matematika otentik dan tingkat kemampuan berbahasa Indonesia siswa. Penelitian ini adalah penelitian eksperimen semu dengan menggunakan desain faktorial 2x2 dan melibatkan sampel sebanyak 80 orang siswa. Data tentang kemampuan memecahkan masalah diperoleh dengan menggunakan test dalam bentuk esay yang terdiri dari 5 buah soal. Data dalam penelitian ini dianalisis menggunakan uji statistik ANAVA dua jalur dan uji Tukey sebagai uji lanjutan. Hasil penelitian menunjukkan bahwa 1) ada pengaruh positif penerapan strategi pemecahan masalah berbasis masalah matematika otentik terhadap kemampuan memecahkan masalah matematika pada siswa dengan kemampuan berbahasa Indonesia tinggi, 2) ada pengaruh negatif penerapan strategi pemecahan masalah berbasis masalah matematika otentik terhadap kemampuan memecahkan masalah matematika pada siswa dengan kemampuan berbahasa Indonesia rendah, 3) ada interaksi antara pengaruh penerapan strategi pemecahan masalah berbasis masalah matematika otentik dan tingkat kemampuan berbahasa Indonesia siswa. Data tentang kemampuan memecahkan masalah diperoleh dengan menggunakan instrumen test dalam bentuk test esay dengan jumlah soal test sebanyak 5 buah. Data dalam penelitian ini dianalisis dengan statistik uji ANAVA dua jalur dan uji Tukey sebagai uji lanjutan. Hasil penelitian menunjukkan bahwa 1) ada pengaruh positif penerapan strategi pemecahan masalah berbasis masalah matematika otentik terhadap kemampuan memecahkan masalah matematika pada siswa dengan kemampuan berbahasa Indonesia tinggi, 2) ada pengaruh negatif penerapan strategi pemecahan masalah berbasis masalah matematika otentik terhadap kemampuan memecahkan masalah matematika pada siswa dengan kemampuan berbahasa Indonesia rendah, 3) ada interaksi antara pengaruh penerapan strategi pemecahan masalah berbasis masalah matematika otentik dan tingkat kemampuan berbahasa Indonesia siswa.

Pengembangan Perangkat Pembelajaran Matematika Untuk Model Pembelajaran Penalaran Dan Pemecahan Masalah (Mp3m) Berorientasi Masalah Terbuka Sebagai Upaya Meningkatkan Aktivitas Dan Prestasi Belajar Siswa Kelas VII

This study aimed at developing mathematics instructional materials based on reasoning and problem solving model with open ended problem oriented which valid, practical, and effective for the seventh grade student. In this study student's handbooks, teacher's instructional guide, and lesson plans were developed. Validity, practicality, and effectiveness of instruments were controlled based on expert's validator, teacher's and student's responses, and the result of the try out. Plomp's development procedure was applied to conduct the study which consists of five stages, namely: (1) preliminary investigation, (2) design, (3) realization/construction, (4) test, evaluation, and revision, and (5) implementation. For the purpose of the study, only the four stages were carried out. The implementation stage could not be involved because of the research limitation. The result of this study showed that the developed instructional materials have fulfilled the criteria of validation value, practicality, and effectiveness. The try out result showed that students were highly involved in teaching and learning activities that affected their high achievement in mathematics. Considering the good result of the try out, it is suggested that the mathematics instructional materials based on reasoning and problem solving model with open ended problem oriented should be implemented in teaching mathematics in the seventh grade of junior high school. Moreover, instructional materials that have been successfully developed in this study, can be used as a guidelines for teacher to develop instructional mathematics with the characteristic of the instructional both in term of developing procedures and process to see the quality of the instructional materials.
