The problem of mathematics learning often happens in mathematics teaching that seems far from the real problem. Realistic mathematics learning can help students to understand about mathematics concepts that abstract for them. If the teachers use real context in mathematics learning, students will be more attracted and interested. The purpose of this research is to look at the effect of realistic mathematics learning towards student's mathematical disposition. The method of this research is descriptive quantitative. The subjects were 35 students of SMP N 14 Yogyakarta grade 7 and this research held in one month. The instrument is students' mathematical disposition scale questionnaire. The students fill the questionnaire before and after they are given a treatment. The result of the questionnaire was analyzed using descriptive statistics, by looking at the average before and after treatment and categorized according to the average value. Based on the results of the descriptive statistical analysis showed that an average of students’ mathematical disposition has increased. The average value of students in pre-treatment is 96.02 with the medium category and then after treatment is given to the 109.44 with the high category
数学学习问题经常发生在数学教学中，似乎与实际问题相去甚远。现实主义数学学习可以帮助学生理解抽象的数学概念。如果教师在数学学习中使用真实的语境，学生会更有吸引力和兴趣。本研究的目的是观察现实主义数学学习对学生数学倾向的影响。本研究采用描述性定量研究方法。受试者为SMP N 14日惹7年级的35名学生，本研究在一个月内进行。工具为学生数学倾向量表。学生们在接受治疗前后填写问卷。采用描述性统计方法，通过观察治疗前后的平均值，对问卷结果进行分析，并根据平均值进行分类。基于描述性统计分析的结果表明，学生的平均数学倾向有所提高。中等类别的学生在治疗前的平均值为96.02，然后在治疗后给予高类别的学生109.44

Tujuan dari penelitian ini adalah mendeskripsikan hasil analisis kesalahan dan scaffolding yang diterapkan dalam memperbaiki kesalahan matematika mahasiswa ketika menyelesaikan persamaan diferensial. Jenis penelitian merupakan penelitian kualitatif deskriptif. Subyek penelitian adalah mahasiswa program studi Pendidikan Matematika IKIP Budi Utomo Malang yang menempuh matakuliah Persamaan Diferensial. Hasil analisis kesalahan menunjukkan bahwa kesalahan yang muncul dalam menyelesaikan persamaan diferensial adalah kesalahan konseptual, prosedural dan faktual. Secara umum, penyebab kesalahan adalah karena mahasiswa tidak mengoptimalkan pengetahuan awal yang sudah dimiliki terkait konsep turunan dan integral dan mahasiswa belum sepenuhnya memahami konsep dan prosedur dalam penyelesaian persamaan diferensial. Selain itu, mahasiswa juga sering menyelesaikan persamaan diferensial dengan hanya melihat dan meniru contoh yang sudah diberikan. Perbaikan kesalahan dilakukan melalui penerapan scaffolding yang merupakan variasi dari pemberian petunjuk, handout dan penjelasan pada mahasiswa. Variasi penerapan scaffolding juga didampingi dengan pemberian umpan balik dan motivasi terhadap mahasiswa. Variasi penerapan scaffolding ditujukan agar mengoptimalkan kemampuan mahasiswa dalam menyelesaikan persamaan diferensial. Mahasiswa juga lebih mandiri dan terlibat aktif dalam pembelajaran. Jadi, selain mampu memperbaiki kesalahannya mahasiswa juga memperoleh pemahaman yang lebih mendalam terkait penyelesaian persamaan diferensial sekaligus meningkatkan sikap dan performanya dalam pembelajaran.
