This study aimed to describe and compare the students’ fluency, flexibility, and originality in solving non-routine problems in the Palembang context. They were depicted from the student’s fluency, flexibility, and originality of solving the horizontal and vertical mathematization forms. This qualitative study employed. The subjects of this study were 30 students of grade nine of junior high schools in Palembang. The instruments used were tests and interviews. The tests were employed to investigate the written horizontal and vertical mathematizations forms. Meanwhile, the interviews were to explore the students’ ideas with inadequately detailed answers. Then, the test and interview data were reduced and grouped based on the indicators of creativity. The reduced data were presented in a descriptive form for conclusions. The results of the data analysis showed that the high-ability students were the most fluent and flexible in solving the problems. Still, the provided solutions were less original and tended to use formal mathematics in the forms of formulas, symbols, and operations. Meanwhile, the moderate-ability students tended to start to solve problems by simplifying them, then presenting them in visual images. The answer sheets of the moderate-ability students revealed their fluency in understanding the problems and solutions, flexibility, and originality of thinking. This study obtained different results from the low-ability students who tended to have difficulties understanding the problems and made many errors in solving them.  Such a condition showed their inability to write the known data and relate the data to other facts they had already learned. As a result, their answers did not represent fluency, flexibility, and originality.

This research is a descriptive study that aims to describe the scaffolding conducted by the teacher in helping students and students’ strategies in solving problems. The subjects of this research were 20 students grade IX of junior high school number 3 Palembang. The instruments used in this study were field notes, observation sheets, student worksheets and interviews. Based on the research results, scaffolding can help solve students’ problem solving. Scaffolding in form a written questions and directed guidance with step by step are as a bridge in solving problems. Scaffolding which starts with sketching can be teacher feedback in knowing the concept of student images. Differences in students solution and student strategies are influenced by prior knowledge, background experience, intellectual abilities, and writing abilities in mathematical language.

Penelitian ini merupakan penelitian pengembangan yang bertujuan menghasilkan Lembar Kerja Peserta Didik (LKPD) berbasis Inkuiri Terbimbing pada Materi Transformasi Geometri yang valid, praktis dan efektif. Prosedur pengembangan yang digunakan terdiri dari tahap preminary (persiapan dan pendesainan) dan tahap prototyping menggunakan alur Formative Evaluation (expert reviews, one-to-one, small group dan field test). Subjek ujicoba dalam penelitian ini ialah peserta didik kelas XI IPA 1 MAN 1 Lahat. Hasil penelitian menunjukkan bahwa LKPD berbasis Inkuiri Terbimbing pada Materi Transformasi Geometri valid, praktis, efektif. Tahap expert reviews didapatkan hasil LKPD valid dengan skor kevalidan 4,07. Tahap one-to-one dan small group didapatkan LKPD praktis dengan skor kepraktisan 3,87 dan 4,20. Keefektifan dilihat dari hasil pengerjaan LKPD dan post-test. Dari hasil pengerjaan  LKPD diperoleh nilai semua peserta didik pesera didik diatas KKM > 60 dan hasil post-test  diperoleh rata-rata nilai peserta didik 73,71 yang termasuk kategori baik dan diatas nilai KKM > 60
