Reflective thinking is one of the high-level thinking skills that learners must possess. This study aimed to determine the effectiveness of Problem Based Learning (PBL) model and to describe the students' reflective mathematical thinking ability for each type of learning styles (visual, auditory, and kinesthetic). This research used a mixed method. The research class was taken with cluster random sampling. The subjects of this study were 6 students of class in one of junior high school in Purworejo which were selected by purposive sampling by selecting 2 students from each type of learning style. The data collection by using tests, questionnaires, and interviews. The results showed (1) PBL was effective in achieving students’ reflective mathematical thinking ability; (2) mathematical reflective thinking ability of visual subject was unable to draw the analogy of the problems and the visual subject was unable to identify relevant data. The auditory subject was unable to explain correctly the concept used in drawing sketches and unable to understand and identify the concepts. In addition, the auditory subject was less able to identify relevant data. Whether the kinesthetic subject made a mistake in drawing the analogy but he was unable to mention the problems that existed and could not identify the relevant data. In addition, the kinesthetic subject was less able in doing proof by using the concept involved in the proof of argument.

Learning process in the 21st century, learners are not only expected to have a high understanding of concepts, but also HOTS. Therefore, the need to be presented about HOTS as well as its analysis to find out the ability of students on these HOTS skills. This study aimed to analyze the form of HOTSbased Essay test in Mathematics lessons focused in trigonometry. This research was conducted with a descriptive quantitative and qualitative approach. Samples were taken from high school students of class X SMA Negeri 1 Mandirancan in small class trials, amounting to 36. Quantitative analysis to look at the characteristics of instruments and item with rasch model. Qualitative data analysis was conducted using source triangulation and techniques on the factual condition of instrument. Based on the analysis, the problem item that is not valid enough there is only 1 out of 10 items, that is item number 1. Item measure in this math Essay test question is classified into 4 categories, that is 1 item is very difficult, 4 items are difficult, 4 items are categorized easily and 1 category item is very easy. Based on the output of the person fit, can be seen, a total of 52.78% of students can complete the HOTS Math essay test well, but the level of person ability is lower than the quality of the item judging by the reliability value of the person and item. In conclusion, the essay test instrument HOTS Mathematics developed tested valid and reliable and has adequate characteristics

Students need the ability to solve word problems can connect mathematics with the context of everyday life. However, students experience many difficulties and need assistance in the form of scaffolding can to solve word problems well. Dynamic assessment is an alternative approach to constructing the form of scaffolding that student need to solve mathematical word problems. This study aimed to analyze the students' difficulties in solving word problems and the required form of scaffolding through dynamic assessment. The subjects of this study consisted of 177 students spread across 10 public junior high schools in Jeneponto Regency, South Sulawesi Province, Indonesia. There was a four-word problem tested and analyzed using dynamic assessment. Student solutions were grouped based on the type and form of scaffolding needed: level 5 (no solution), level 4 (without analysis/unrepresentative), level 3 (computational error), level 2 (incomplete procedure), level 1 (lack of thoroughness in the final stage). The form of scaffolding is constructed to help students solve mathematical word problems step by step at each level. The use of scaffolding accompanied by instructions helps students develop word problem-solving skills. Dynamic assessment can be considered to be integrated with the mathematics learning process that supports scaffolding construction to solve students' word problems.

ABSTRAKPolitik Hukum Pidana Melalui Sarana Non Penal Dalam Menanggulangi Tindak Pidana Di Bidang Pendidikan. Tindak pidana yang menjadi fokus dalam penelitian ini adalah tindak pidana yang dilakukan guru dalam melaksanakan tugas/profesi keguruannya. Penelitian ini merupakan penelitian yuridis-normatif. Data-data yang relevan dengan penelitian ini lebih difokuskan pada data sekunder yang diperoleh melalui studi literatur (literate studi), yang selanjutnya dianalisis secara deskriptif-analitis. Dari penelitian ini diperoleh hasil bahwa: pertama, jenis-jenis tindak pidana di bidang pendidikan secara umum, dan tindak pidana yang dilakukan guru dalam melaksanakan tugas/profesinya. Kedua, Kebijakan hukum pidana saat ini yang digunakan terhadap tindak pidana yang dilakukan guru dalam melaksanakan tugasnya, terbatas pada KUHP dan Undang-undang Nomor 35 Tahun 2014 tentang perlindungan anak, yang dikaitkan dengan tindak pidana murni dan tindak pidana refleksi kedisiplinan. Ketiga, upaya penanggulangan kejahatan melalui sarana non penal. Usaha non penal dalam menanggulangi kejahatan sangat berkaitan erat dengan usaha penal. Upaya non penal ini dengan sendirinya akan sangat menunjang penyelenggaraan peradilan pidana dalam mencapai tujuannya. Pencegahan atau menanggulangi kejahatan harus dilakukan pendekatan integral yaitu antara sarana penal dan non penalKata Kunci : Politik Hukum Pidana, Non Penal, Pendidikan

Mathematics is a symbol of rationality and the highest intellectual achievements of human civilization. Mathematics has always been seen as abstract and formal knowledge. However, in the last few decades, the idea has emerged that mathematics is a knowledge that develops in human cultural activities. The concept of mathematics in culture is widely known as ethnomathematics. This paper aims to briefly describe the history, criticism, and challenges of ethnomathematics, the thoughts of ethnomathematics experts, and their influence in learning mathematics today. The development of ethnomathematics gave rise to a field of study covering aspects of anthropology and the history of mathematics, non-formal mathematics practice, traditional mathematics, and multicultural learning. Various research results indicate that ethnomathematics contributes to improving school mathematics. Although culture has an important role in learning mathematics, to integrate it requires comprehensive efforts to overcome various obstacles. Teachers need to improve competencies related to understanding local culture to maximize the transformation of ethnomathematics learning in the classroom.

Effectiveness of SL-PTT activity requires dynamic creativity in concocting the use of various methodsof learning appropriate. Effectiveness is the relationship between the objectives and results to beachieved, as the effects caused by their activities. The purpose of this study wanted to clarify theeffectiveness of the activities of rice based SL-PTT on the increase in the competencies (knowledge,skills and attitudes) learning objectives (farmers) in the province of Banten. Location of the studyconducted in four districts in Banten province, namely : Serang, Pandeglang, Lebak and Tangerang.respondents and the research informants purposively determined in accordance with the problems andresearch objectives. Data collection through focus group discussions and interviews. Data wereanalyzed by descriptive analytical to explain the effectiveness of SL-PTT activity as measured by theparameters level of knowledge, skills and attitude of the respondent farmers. The level of learningeffectiveness SL-PTT rice in Banten province there is a gap between the level of competence of thefarmer participants and non participants SL-PTT rice.
