Selection of appropriate learning approaches and strategies, will facilitate the achievement of these learning activities. Similarly, in mathematics learning activities in PGSD (department of elementary school preservice teacher), which is demanding the development of a high level of mathematical ability as well as critical thinking skills. However, not many people are trying to look for other factors in addition to the approach/learning strategy, which is possible to contribute to the development of critical thinking skills, such as interest factor majors students (IPA [science] and non-IPA [non-science]) as well as mathematical prior knowledge which has been owned previously. In addition, affective aspects that accompany any critical thinking skills (critical disposition) is a study that is still rare. This paper briefly present to peel the election factor of approaches and learning strategies, ie, problem based learning with "MURDER" strategy, shared interests and their interaction majors and mathematical prior knowledge of the result of performance of critical thinking skills and dispositions of PGSD students. Keywords : problem-based learning, the "MURDER" strategy, mathematical prior knowledge, critical thinking skills, critical thinking disposition.

Interaksi pbl-murder, minat penjurusan, dan kemampuan dasar matematis terhadap pencapaian kemampuan berpikir dan disposisi kritis

Penelitian ini bertujuan untuk mengetahui adanya pengaruh pendekatan kontekstual berstrategi TTW dan pendekatan konvensional serta membuktikan bahwa pendekatan kontekstual berstrategi TTW lebih baik daripada pendekatan konvensional terhadap kemampuan pemecahan masalah matematis siswa. Metode yang digunakan yaitu kuasi eksperimen dengan desain the nonequivalent control group design. Populasi dalam penelitian ini yaitu siswa kelas IV SD se-kecamatan Cisarua. Sementara sampelnya adalah siswa kelas IV SDN Cisalak IV sebagai kelas eksperimen dan Cisalak II sebagai kelas kontrol. Instrumen yang digunakan berupa tes kemampuan pemecahan masalah matematis, lembar observasi aktivitas siswa dan kinerja guru, angket dan wawancara. Hasil penelitian dengan taraf signifikansi  = 0,05 menunjukkan bahwa pendekatan kontekstual berstrategi TTW dan pendekatan konvensional memberikan pengaruh terhadap kemampuan pemecahan masalah matematis siswa serta pembelajaran menggunakan pendekatan kontekstual berstrategi TTW lebih baik secara signifikan daripada pendekatan konvensional terhadap kemampuan pemecahan masalah matematis siswa.
