Abstract: The objectives of this research were to investigate: (1) which learning model of the TSTS model, the NHT model, and the direct learning model resulted in a better learning achievement in mathematics; (2) which students of the students with mathematical-logical, interpersonal, and linguistic intelligence had a better learning achievement in mathematics; (3) in each category of the multiple intelligences, which learning model of the TSTS model, the NHT model, and the direct learning model resulted in a better learning achievement in mathematics; and (4) in each learning model, which students of the students with mathematical-logical, interpersonal and linguistic intelligence had a better learning achievement in mathematics. This research used the quasi experimental research method with the factorial design of 3 x 3. Its population was all of the students in Grade VII of Junior Secondary Schools of Metro City. The size of the samples was 269 students. They were taken by using the stratified cluster random sampling technique. The instruments to gather the data of the research were test of learning achievement in mathematics and questionnaire of multiple intelligences. The proposed hypotheses of the research were tested by using the two-way analysis of variance with unbalanced cells. The results of the research were as follows. 1) The TSTS model resulted in a better learning achievement than the NHT model and direct model, and the NHT model resulted in a better learning achievement than the direct learning model. 2) The students with mathematical-logical intelligence had a better learning achievement than those with interpersonal and linguistic intelligences, and the students with interpersonal intelligence had a better learning achievement than those with linguistic intelligence. 3) In the students with mathematical-logical intelligence, the TSTS model resulted in a better learning achievement than the cooperative learning model of the NHT model, the TSTS model and the NHT model resulted in the same learning achievement as the direct learning model. In the students with interpersonal intelligence, the TSTS model resulted in the same learning achievement as the NHT and direct learning models, and the NHT model resulted in a better learning achievement than the direct learning model. In the students with linguistic intelligence, the TSTS and the NHT model sresulted in the same learning achievement as the direct learning model. 4) In the TSTS model, the students with mathematical-logical intelligence had the same learning achievement as those with interpersonal intelligence but had a better learning achievement than those with linguistic, and interpersonal intelligence had the same learning achievement those with linguistic intelligence.

Abstract

The process of thinking is the steps that a person uses in receiving, processing, concluding, and reusing the information obtained to resolve the issues related to solve the problem of the memory. While cognitive style is an activity that became a characteristic of learners in the functioning of mental activities in the field of cognitive (thinking, remembering, processing information, organizing, solving problems, and making decisions) which is consistent. Cognitive style has a major role when utilized in an effort to improve the effectiveness of the learning process. Cognitive styles are divided into two, namely, Field Independent (FI) and Field Dependent (FD). This research is descriptive qualitative which describes the process of thinking of students in solving mathematical problems on material combinations and permutations. The data collection method in this study using GEFT tests to determine cognitive styles of students, test description of material combinations and permutations to obtain the thinking process of students, and interviews. Based on cognitive style, students are grouped into 2 groups: FI and FD, and then subsequently selected two students from two groups of students from the FI and FD to give test of thinking ability and then interviews. Data analysis technique used Miles and Huberman, data reduction, display, and conclusion drawing / verification. Based on the analysis we concluded that students who have the cognitive styles FI tend to have a conceptual thought process. Likewise, students who have the cognitive style FD, these students are also likely to have a conceptual thought process. The process of conceptual thinking is the thought process which solves problems by using the concept that has been owned by the results of studies.

Abstract

Pembelajaran kooperatif Tipe Student Facilitator and Explaining (SFE) adalah suatu model pembelajaran dimana siswa belajar mempresentasikan ide atau pendapatnya pada rekan yang lain, sedangkan alat peraga kotak imajinasi merupakan salah satu jenis alat peraga tiga dimensi yang berbentuk kubus dan balok. Penelitian ini adalah penelitian eksperimen semu (quasy experiment) yang bertujuan untuk mengetahui pembelajaran dengan model pembelajaran SFE berbantuan alat peraga kotak imajinasi dan pembelajaran langsung sekaligus mengetahui kecerdasan spasial. Penelitian dilakukan di SMP Ma’arif 1 Metro Tahun Pelajaran 2016/2017 dengan populasi seluruh siswa kelas VIII yang terdiri dari 3 kelas, pengambilan sampel dengan cara cluster random sampling. Analisis data pada penelitian ini menggunakan uji analisis variansi dua jalan sel tak sama dengan taraf signifikansi 0,05 diperoleh nilai Fobs 5,89 yang merupakan anggota Daerah Kritis {F│F >4,028} sehingga H0 ditolak. Hal ini berarti bahwa terdapat perbedaan prestasi  belajar antara siswa yang diajar dengan menggunakan model pembelajaran  SFE berbantuan alat peraga kotak imajinasi dan model  pembelajaran langsung. Kemudian dalam perhitungan hipotesis dengan taraf signifikansi 0,05 diperoleh nilai Fobs 74,88 yang merupakan anggota daerah kritis{F│F>3,178}sehingga H0  ditolak. Ini berarti semua kategori kecerdasan spasial siswa tinggi, sedang dan rendah memberikan efek yang berbeda terhadap prestasi belajar matematika siswa.

Abstract

[Bahasa]: Penelitian ini bertujuan untuk mengetahui pengaruh penerapan pembelajaran picture and picture (PaP) terhadap hasil belajar matematika siswa, pengaruh kategori kecerdasan spasial (tinggi, sedang dan rendah) terhadap hasil belajar siswa, dan interaksi antara pembelajaran PaP dengan kecerdasan spasial yang terjadi pada hasil belajar siswa. Penelitian quasi experimental dipilih untuk mencapai tujuan penelitian tersebut. Sampel penelitian adalah siswa MTs sebanyak 29 orang sebagai kelompok eksperimen dan 31 orang sebagai kelompok kontrol. Analisis data menggunakan analisis variansi (anava) dua jalan kemudian dilanjutkan uji Sceffe' jika diperlukan. Hasil penelitian menunjukan terdapat pengaruh pembelajaran PaP terhadap hasil belajar siswa, terdapat pengaruh kecerdasan spasial terhadap hasil belajar siswa, dan tidak terdapat interaksi antara pembelajaran PaP yang diterapkan dan masing-masing kategori kecerdasan spasial terhadap hasil belajar siswa. Berdasarkan hasil penelitian, dapat disimpulkan pembelajaran PaP bisa digunakan untuk meningkatkan hasil belajar matematika siswa khususnya pada materi segiempat dan tingkat kecerdasan spasial mempengaruhi hasil belajar siswa. Namun, belum ditemukan apakah interaksi keduanya mempengaruhi hasil belajar matematika siswa sehingga diperlukan penelitian lebih lanjut. Kata kunci: Pembelajaran Picture and Picture; Kecerdasan Spasial; Hasil Belajar; Matematika [English]: The research was aimed at examining the effect of picture and picture (PaP) learning on students’ mathematics achievement, the effect of students' spatial intelligence on the achievement, and the interaction between PaP leaning and spatial intelligence toward the achievement. The quasi-experimental was used to achieve the research purposes. The sample was 29 junior high students as experimental group and 31 students as control group. Data analysis employed two paths of variance analysis (anova) and followed by Sceffe test if necessary. The research found that there was effect of PaP learning on the students’ achievement, spatial intelligence had influence on the achievement, and there was no interaction between PaP learning and the level of spatial intelligence toward the students’ achievement. The research concluded that PaP learning can be used to improve students’ achievement in mathematics especially for rectangular topic and the level of spatial intelligence affect students’ mathematics achievement.  However, this research has not found that the interaction of PaP learning and spatial intelligence affect the achievement. Thus, a further research is required to examine the interaction. Keywords: Picture and Picture; Spatial Intelligence; Students’ Achievement; Mathematics
