Buku ini ditulis oleh John Mason dengan Leone Burton dan Kaye Stacey tahun 1982. Buku ini menjadi rujukan dari beberapa peneliti lainnya. Di buku ini, Mathematical Thinking proses dibagi menjadi 2 pasang proses yaitu Specialising and Generalising kemudian Conjecturing and Convincing. Namun, istilah “Mathematical Thinking”memiliki beberapa pergeseran makna sesuai dengan perkembangan dari tahun ke tahun. Selain itu, paper ini juga membahas kaitan antara “Mathematical Thinking” atau berpikir matematis dengan ways of understanding dan ways of thinking. Kata Kunci: Mathematical Thinking; ways of understanding; ways of thinking Abstract:Early term of \"Mathematical Thinking\" refers to the term from a very famous book entitled Thinking Mathematically with the current number of citations reaching 1781. This book was written by John Mason with Leone Burton and Kaye Stacey in 1982. This book became a reference for several other researchers. In this book, the Mathematical Thinking process is divided into 2 pairs of processes, namely Specializing and Generalising then Conjecturing and Convincing. However, the meaning of mathematical thinking has changed according to developments from year to year. In addition, this paper also discusses the relationship between \"Mathematical Thinking\" with ways of understanding and ways of thinking.conclusions.","PeriodicalId":486240,"journal":{"name":"∑igma","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135257049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ma’Arif Ambulu Jember yaitu media pembelajaran yang digunakan sangatlah minim, guru menunggu adanya media dari sekolah, pada pembelajaran sehari-hari guru terkadang menggunakan aplikasi Whatsapp untuk memberi materi berupa file pdf yang nantinya siswa akan diminta mempelajarinya secara mandiri. Penerapan Problem Based Learning (PBL) berbantuan animaker bertujuan untuk meningkatkan aktivitas dan hasil belajar siswa pokok bahasan statistika dengan responden 30 siswa di MTs Ma’arif Ambulu. Pengumpulan data menggunaakan observasi, dokumentasi dan wawancara, Peneliti menggunakan observasi aktivitas guru dan tes hasil belajar siswa sebagai analisis data. Peneliti juga memilih penelitian tindakan kelas (PTK) yang menggunakan 2 siklus. Rata-rata hasil penelitian pada siklus I disebutkan presentase aktivitas guru sebesar 83.3% dan prsentase aktivitas siswa 65%. Kemudian pada siklus II presentase aktivitas guru sebesar 93,3% dan presentase aktivitas siswa sebesar 85%. Untuk presentase hasil tes belajar siswa pada siklus I sebesar 76,3% termasuk kriteria baik. Kemudian untuk siklus II presentase yang didapatkan sebesar 81,3% yang termasuk dalam kriteria baik. Jadi terbukti dengan adanya penelitian ini dapat meningkatkan aktivitas dan hasil belajar siswa.Ahiri, J. (2017). Penilaian Autentik Dalam Pembelajaran.

{"title":"STUDENT’S DIFFICULTIES IN TRANSFORMATION GEOMETRY COURSE VIEWED FROM VISUALIZER VERBALIZER COGNITIVE STYLE","authors":"Rohmah Indahwati","doi":"10.53712/sigma.v9i1.1993","DOIUrl":"https://doi.org/10.53712/sigma.v9i1.1993","url":null,"abstract":"This study aims to determine the difficulties of students in the geometry transformation course in terms of visualizer and verbalizer cognitive style, especially in the concept of mapping a transformation. The research subjects were students of the transformation geometry class at the Mathematics Education Study Program at the University of Madura. This research is a qualitative descriptive study. Based on the results of the study, it was found that the difficulties of students with cognitive visualizer and verbalizer styles tended to be the same, which included (1) difficulty visualizing the definition of a transformation (2) difficulty in proving a transformation (3) difficulty determining the result area of a mapping. The Visualizer subject answers all the questions given and tries to describe the definition of the transformation given, although it is still not precise, it is better than the subject verbalizer. Verbalizer subjects, who are essentially easier to process information in the form of writing, are constrained by the arrangement of mathematical sentences and mathematical symbols which make the subject reluctant to try to answer questions. From the results of the analysis it was also revealed that the causes of the subject's difficulties were influenced by several aspects, namely, lack of mastery of basic geometric concepts, weak of reasoning ability and difficulties in mathematical operationsKeywords: Student Difficulties, Transformation Geometry, Visualizer Verbalizer Cognitive Style","PeriodicalId":486240,"journal":{"name":"∑igma","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134932085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
