This study was a quasi experimental research using 2 independent variables (learning model and students’ learning style) and 1 dependent variable (mathematics learning achievement). The data collection was conducted using documentation, test, and questionnaire. Technique of analyzing data used was a 3x3 two-way ANAVA with unbalanced cells. The samples of the research were taken by using the combination of stratified random and cluster random sampling techniques. The result of research showed that: (1) the students given PC learning model had better learning achievement than those given TAI model, those given PC had better learning achievement than those given STAD, while those given TAI and STAD models had equal good learning achievement; (2) the students with auditory and visual learning styles had equal good learning achievement, those with auditory had better learning achievement  than those with kinesthetic, and those with visual had better learning achievement  than those with kinesthetic; (3) in each learning model, the students with auditory and visual learning styles had equal good learning achievement, those with auditory had better learning achievement  than those with kinesthetic, and those with visual had better learning achievement  than those with kinesthetic, (4) in each learning style, the students given PC learning model had better learning achievement than those given TAI model, those given PC had better learning achievement than those given STAD, while those given TAI and STAD models had equal good learning achievement.Keywords: Pair  Checks, Team  Assisted  Individualization,  and   Student Teams Achievement Divisions

Abstract

ABSTRAK   Museum Kereta Api Ambarawa terletak di pusat Ambarawa, satu-satunya museum peninggalan berteknologi kuno di Indonesia yang digunakan sebagai alat transportasi bangsa Indonesia sebelum kemerdekaan sampai tahun 1964. Dalam museum ini terdapat 21 lokomotif uap yang berada di utara dan barat museum, 5 lokomotif uap yang berada di depo 3 diantaranya dapat beroperasi dengan baik, selain itu terdapat pula 3 mesin ketik, 3 mesin hitung, beberapa pesawat telpun dan peralatan kuno lainnya. Museum ini mempunyai nilai historis dari alat transportasi berupa ketel uap yang merupakan implikasi penemuan oleh James Watt. Di tempat ini juga menyediakan paket wisata dengan menumpang kereta api tenaga uap melalui rel yang bergerigi dan kereta lori dengan rute Ambarawa-Bedono Ambarawa-Tuntang. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang berpengaruh terhadap jumlah kunjungan wisatawan dan mengestimasi modelnya. Teori yang digunakan dalam analisis adalah teori permintaan. Penelitian dilakukan di obyek wisata Museum Kereta Api Ambarawa Kabupaten Semarang dengan 78 responden. Estimasi penelitian diformulasikan dalam bentuk persamaan tunggal (single equation), dengan variabel dependen adalah permintaan pariwisata yang diproksi dengan jumlah kunjungan wisatawan, sedangkan variabel independennya adalah harga pariwisata yang diproksi dengan kemauan membayar (willingness to pay /WTP), harga pariwisata obyek wisata lain yang diproksi dengan WTP obyek wisata lain, pendapatan, biaya perjalanan, biaya perjalanan obyek wisata lain (di luar Kabupaten Semarang), jarak, pendidikan, umur, persepsi daya tarik obyek wisata,  asal wisatawan (wisnus dan wisman),  komunitas, jenis kelamin,   promosi pariwisata,   dan  kunjungan sebelumnya. Hasil penelitian menunjukkan bahwa variabel-variabel yang signifikan adalah variabel WTP, WTP_owl, dan  PENDP signifikan pada = 1%; dan BPERJ, PENDI, dan UM  signifikan pada = 5%.dan diperoleh nilai R2 sebesar 0,9774 yang berarti bahwa 97,74% dari variasi variabel jumlah kunjungan wisatawan mampu dijelaskan oleh variasi  (himpunan) variabel WTP, WTP_owl, pendapatan, biaya perjalanan, biaya perjalanan_owl, jarak, pendidikan, umur, persepsi, asal wisatawan, komunitas, jenis kelamin, promosi dan kunjungan sebelumnya. Sedangkan sisanya sebesar 2,26% dari variasi variabel jumlah kunjungan wisatawan dijelaskan oleh variasi faktor-faktor atau variabel-variabel lain di luar model. Dengan nilai R2 yang tinggi yaitu sebesar 97,74%  semakin baik kualitas model, karena semakin dapat menjelaskan hubungan antara variabel dependen dan independen.   Kata kunci:  permintaan, WTP, pendapatan, jumlah kunjungan wisatawan

Abstract: The aim of the research was to determine the effect of learning models on learning achievement viewed from students’ interpersonal intelligence. The learning models compared were cooperative learning model Numbered Heads Together (NHT) with Realistic Mathematics Approach (RMA) approach, Think Pair Share (TPS) with Realistic Mathematics Approach (RMA) and direct learning. This research was a quasi-experimental research using factorial design of 3x3. The population of the research was all students of the Junior High Schools in Grobogan regency. The samples of the research were seven grade students of SMP Negeri 2 Purwodadi, SMP Negeri 2 Grobogan and SMP Negeri 7 Purwodadi in Grobogan regency (88 students for for first experimental class, 96 students for second experimental class, and 92 students for control class). The samples were chosen by using stratified cluster random sampling. In collecting the data, the instruments used were multiple-choice test of learning achievement in mathematics and student interpersonal intelligence questionnaire. The technique of analyzing the data was unbalanced two-ways Anova. The results of the research are as follows: (1) the cooperative learning model NHT with RMA give better achievement in mathematics than cooperative learning model TPS with RMA, and both result in a better learning achievement in mathematics than the direct learning model; (2) there are no any differences in the learning achievement in mathematics of the students with high, medium or low interpersonal intelligence; (3) in each interpersonal intelligence, the cooperative learning model NHT with RMA give better achievement in mathematics than cooperative learning model TPS with RMA, and both result in a better learning achievement in Mathematics than the direct learning model; (4) in each learning model, the students with high, medium and low interpersonal intelligence have the same learning achievement in mathematics.Keywords:          NHT, TPS, RMA, interpersonal intelligence, learning achievement in mathematics
