摘要：The purpose of this researchwastoreveal if there was any significant difference in students’ logical thinking abilities and mental models of school chemistry based on theirgradelevel.This study was also aimed to investigate whether the logical thinking ability was correlated with the mental mo-dels of school chemistry.The study was conducted using the cross-section method and included 124teachers-to-bewho were students in the department of chemistry education at a university of teachers training in Bandung.The data were collected through the testof logical thinking (TOLT) and the diagnostic test of school chemistry mental models(DTSCM).The TOLT instrumentincluded five sub-scales: proportional reasoning,controlling variables,combinational reasoning,probabilistic reasoning,and correlational reasoning.The DTSCM instrumentincluded five sub-matters: stoichiometry,ther-mochemistry,chemical equilibrium,rate of reaction,and acid-base.Research findings showed thatbased on students’ grade level,there was a significant difference in themean of mental models of school chemistry but not in the mean of logical thinking abilities.The findingsalso indicated thatthe logical thinking level ofthe teachers-to-be was correlated with the mental models of school chemistry.
其他摘要：Tujuan penelitian ini adalah untuk mengungkapkan apakah ada perbedaan yang signifikan dalam kemampuan berpikir logis mahasiswa calon guru dan model mental kimia sekolah berdasarkan pada tingkat nilai mereka.Penelitian ini juga dimaksudkan untuk mengetahui apakah kemampuan berpikir logis berkorelasi dengan model mental kimia sekolah.Penelitian ini dilakukan dengan metodecross-sectionyangmeliputi 124 mahasiswa calon guru kimia yang sedang mengikuti kuliah dipro-gram studi Pendidikan Kimia di sebuah LPTK di Bandung.Data dikumpulkan dengan tes kemampuan berpikir logis dan tes diagnostik model mental kimia sekolah.Tes kemampuan berpikir logis meliputi lima skala: penalaran proporsional,variabel kontrol,penalaran kombinasi,penalaran probabilistik,dan penalaran korelasional.Tes diagnostik model mental kimia sekolah mencakup lima masalah: stoichio-metry,thermochemistry,chemical equilibrium,tingkat reaksi,dan asam-basa.Temuan penelitian me-nunjukkan bahwa berdasarkan tingkat nilai mahasiswa,terdapat perbedaan yang signifikan pada rerarta model mental kimia sekolah,tetapi tidak pada rerata kemampuan berpikir logis.Temuan pene-litian juga menunjukkan bahwa tingkat kemampuan berpikir logis para guru kimia berkorelasi dengan model mental kimia sekolah.
