This study was a quasi experimental research using 2 independent variables (learning model and studentsâ 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 twoway 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 achievementÂ than those with kinesthetic, and those with visual had better learning achievementÂ 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 achievementÂ than those with kinesthetic, and those with visual had better learning achievementÂ 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 Â Checks, Team Â Assisted Â Individualization, Â and Â Â Student Teams Achievement Divisions

ABSTRAK Museum Kereta Api Ambarawa terletak di pusat Ambarawa, satusatunya 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 AmbarawaBedono AmbarawaTuntang. Penelitian ini bertujuan untuk menganalisis faktorfaktor 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 variabelvariabel 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 faktorfaktor atau variabelvariabel 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

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 quasiexperimental 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 multiplechoice test of learning achievement in mathematics and student interpersonal intelligence questionnaire. The technique of analyzing the data was unbalanced twoways Anova.

The RME learning model with problem posing provided better learning achievement than conventional one, (2) the students having high creativity had better learning achievement than those having medium and low creativity. The students having medium creativity had better learning achievement than did those having low creativity, (3) students taught by using RME with problem solving having high creativity level had better learning achievement than those having medium and low creativity level and students having medium creativity level had learning achievement as good as the low creativity level. Students taught by using RME with problem posing and conventional model had equal learning achievement in each level of creativity, and (4) students having high creativity level taught by using RME with problem solving had better learning achievement than those taught by using RME with problem posing and conventional model. Students having high creativity taught by using RME with problem posing and conventional model had equally good learning achievement.
