Salah satu standar yang diberikan oleh National Council of Teachers of Mathematics (NCTM) adalah disposisi matematik. Disposisi bukan sekedar merujuk pada sikap tetapi suatu kecenderungan untuk berpikir dan bersikap dalam cara yang positif. Penelitian ini bertujuan untuk menganalisa disposisi matematik dan hubungannya dengan hasil belajar matematika siswa-siswa sekolah menengah atas (SMA). Sampel pada penelitian ini adalah 149 siswa SMA di Bandung. Analisa statistik didasarkan pada korelasi peringkat Spearman dan uji-t. Ditemukan bahwa secara rata-rata, disposisi matematik dari siswa-siswa SMA dikategorikan rendah. Selanjutnya, terdapat korelasi positif dan signifikan antara disposisi matematik dan hasil belajar matematika siswa-siswa SMA, walaupun nilai koefisien korelasinya tidak tinggi. Suatu observasi juga dilakukan untuk menganalisa hubungan ini, dan didapati bahwa walaupun beberapa siswa memiliki disposisi matematik yang baik, kadang kala mereka tidak dapat menyelesaikan ujian dengan baik, karena padatnya kurikulum, dan juga aktifitas sosial mereka, yang membuat hasil belajar matematika mereka lebih rendah. Temuan lainnya adalah bahwa siswa-siswa SMA memerlukan guru-guru matematika dengan lebih banyak strategi mengajar agar mereka dapat memiliki disposisi matematik yang lebih baik. Kata Kunci: Disposisi Matematik, Hasil Belajar Matematika One of the evaluation standards given by the National Council of Teachers of Mathematics (NCTM) was mathematical disposition. Disposition refers not simply to attitudes but to a tendency to think and to act in positive ways. This study aimed to analyze the mathematical disposition and its correlation with mathematics achievement of senior high school (SMA) students. A total of 149 SMA students in Bandung were procured as samples. Statistical analysis was based on the Spearman rank correlation and on the t-test. The findings showed that at average, the mathematical disposition of the SMA students were categorizing low. Furthermore, there was a positive and significant correlation between mathematical disposition and mathematics achievement of the SMA students, though the correlation coefficient was not high. An observation was also made to analyze this correlation, and it was found that though some students have good mathematical disposition, sometimes they could not do the tests well, because of the condensed curriculum, and also their social activities, which make their mathematics achievement become lower. Another finding was that SMA students need teachers with some more mathematics teaching strategy for them to gain better mathematical disposition. Key words: Mathematical Disposition, Mathematics Achievement.

Learning style is a behavior that is intentionally done by students in the form of cognitive, affective and psychological behavior to obtain changes in learning. Information about student learning styles can help teachers determine the learning strategies to be used. This study aims to determine how the learning styles of high school students in Bandung. This is descriptive research, and the sample in this study was 275 students from several secondary schools in Bandung. The learning style measurement instrument used is the "Perceptual Learning Style Preference Questionnaire" (PLSPQ) made by Reid (1987) which states there are six learning styles (visual, tactile, auditory, group or group, kinesthetic, individual), and translated into Indonesian. The results showed that: (1) There were 20.73 percent of students who had only one dominant or "major" learning style. , (2) There are 55.27 percent of students who have more than one dominant learning style, (3) There are 24 percent of students who do not have any dominant learning style. Other results are: The majority of high school students have a kinesthetic learning style (learning through their overall body experience or involved physically in classroom experiences) and or group learning style (learning with other friends in a group) as the dominant learning style.

Mathematical communication ability is important because it can train students thinking and reasoning, develop creative activities, develop problem solving skills and develop ability to convey information. But previous researchs shows that mathematical communication skill still not high, so it still needs to be improved. The purpose of this study is to know the Junior High School students' mathematical communication improvements, and whether there are different improvement between students who acquire Number Head Together cooperative learning model and Ing Ngarsa Sung Tuladha. This comparative designed study used 7 essay mathematical communication problems and response questionaire as the research instruments. The sample of this study were students in two grades VII of SMP Negeri 3 Parongpong, West Bandung. The result shows that the students’ mathematical communication improvement of those who acquire Number Head Together cooperative learning model and Ing Ngarsa Sung Tuladha are both in the moderate category, and they are not different statistically. Another result shows that students really like to learn using Number Head Together or Ing Ngarsa Sung Tuladha cooperative learning model.

This paper describes one way that teachers as educators can face the challenges of the industrial revolution 4.0, namely by instilling and preparing creative and character-based leaders. Education as character building can be implemented using Ki Hajar Dewantara's leadership concepts, namely Ing Ngarsa Sung Tuladha, Ing Madya Mangun Karsa, and Tut Wuri Handayani. The concept of leadership was first adopted as a cooperative learning model which emphasized exemplariness in group learning. The group leader is called tuladha and is the facilitator of the group. Tuladha utilizes the Internet of Things. Before the teaching and learning process in class, information, concepts or ideas, and examples are posted by the teacher to the tuladha. This study is an experimental study with the sample used meeting the prerequisites of the statistical test used. The results showed that students' mathematical problem solving abilities increased significantly using the Ing Ngarsa Sung Tuladha cooperative learning model over the usual method. The category of improving students' mathematical problem solving abilities that obtain the Ing Ngarsa Sung Tuladha cooperative learning model is in the high category.
