Abstract

In order to help students develop their critical thinking skills, teachers need to model the critical thinking skills and dispositions in front of their students. Unfortunately, very rare studies investigating prospective teachers’ readiness in critical thinking dispositions are available in the field of mathematics education. This study was intended to investigate the level of critical thinking disposition of prospective mathematics teachers. Using case study methods, three studies were done in Malang.Three levels of critical thinkers were identified from these case studies namely: non-critical thinker, emergent critical thinker, developing critical thinker. Majority of prospective mathematics teachers’ critical thinking dispositions are at the non-critical thinker level. Only a few of them are at the emergent critical thinker, and very rare at the developing critical thinker level. It can be concluded that prospective mathematics teachers are not critical thinker yet. Teacher education institutions need to reform their curriculum and instructional practices to improve their students critical thinking skills and dispositions.DOI: http://dx.doi.org/10.22342/jme.8.2.3961.145-156

Abstract

The Mathematics students who perform truth-seeking process upon solving mathematical problems were unique. Therefore, the study deems it necessary to know students’ mental structure and mechanism so that they can make the right decision by performing truth-seeking. However, no research has delved into the mental structures and mechanisms of Mathematics students, who tend to grapple with truth-seeking processes extensively. This study was explorative qualitative because the aims to describe the types of mental structure and mechanism of Mathematics students upon the truth-seeking process in solving mathematical problems. The research subjects are four Mathematics students at the University of Jember who perform truth-seeking and can communicate fluently when performing think-aloud. Their responses in the answer sheets drove the determination of research subjects' tendency in truth-seeking. Afterward, the results of think-aloud and task-based interview were put under analysis, so as to determine the types of mental structure and mechanism. The research findings have indicated that (1) all mental structures have been constructed by all research subjects and (2) two types of mental mechanism are evident among the subjects, including the process of interiorization coupled with coordination and another process encompassing interiorization, coordination, and reversal.

Abstract

The purpose of this study is to investigate the patterns of scaffolding contingency in teaching and learning mathematics carried out by three teachers. Contingency patterns are obtained by examining the transcription from video recording of conversation fragments between teachers and students during the provision of scaffolding. The contingency patterns are drawn in three strategies: diagnostic strategy, intervention strategy, and checking diagnosis. The result shows that the three teachers expressed different interaction contingencies in their scaffolding activities: contingent dominant, non-contingent dominant, and pseudo-contingent. It is also found that the learning interaction performed by experienced teachers tends to be contingent dominant compared to novice teachers.Keywords: Contingency, Contingent Dominant, Non-Contingent Dominant, Pseudo Contingent, Scaffolding DOI: http://dx.doi.org/10.22342/jme.8.1.3410.65-76

Abstract

The trends of teaching mathematical thinking and the existence of two thinking skills (critical dan creative thinking) the required by 21st-century skills have created needs for teachers to know their students’ thinking processes. This study is intended to portray how mathematics teachers expect their students showing their thinking processes in students’ written work. The authors surveyed Whatsapp and Telegram group of mathematics teachers. First, the authors shared the result of the literature review and the governmental regulations about the need to develop thinking skills. Second, the authors stated that the potentials of students’ written works as a tool for knowing students’ thinking processes. Third, the authors sent a simple mathematical problem with the topic of algebra and asked the mathematics teachers how should their students answer that problem such that they can easily monitor and assess their students’ thinking processes. A total of 25 teachers participated voluntarily in this survey. Results of the survey were triangulated with direct trial data in lecture classes at both undergraduate and postgraduate levels. The result indicates that participating mathematics teachers do not expect too much for their students to show their thinking processes in written work. Teacher’s focus is mostly on the accuracy and the correctness of their students’ mathematics answer.

This study aims to describe students' written questions in learning using a scientific approach to the Pythagorean Theorem material. Research instruments in the form of worksheets with a scientific approach, observation sheets along with a rubric scoring the quality of student questions, and interview sheets. The research subjects were 32 students of 8A grade of MTsN 9 Banyuwangi. The research took place in four face-to-face learning. The results obtained from this study are the quality of written questions based on the cognitive level and the category of students' ability to ask questions in learning using a scientific approach. The results showed that the written questions formulated by students during the learning activities were distributed with a cognitive level of C1 of 29%, cognitive level C2 of 21%, cognitive level of C3 of 23%, cognitive level of C4 of 19%, and cognitive level of C5 of 8%. None of the students were able to construct questions at the cognitive level C6. Meanwhile, the results of the analysis of individual student questions separately showed that the categories of students' abilities in composing questions were divided into 43.75% low ability, 46.88% medium ability, and 9.37% high ability. The low percentage value of students with high abilities indicates that the teacher must improve the students' questioning abilities. Keywords: question profile, questioning ability, scientific learning

Abstract

The questions asked by the teacher affect students' thinking processes. So, it is necessary to do research that aims to describe what types of questions can provoke students to behave critically. The research subjects were 40 junior high school students around a coffee plantation in Jember, Indonesia. The data collection methods in this study were (1) test, (2) observation, and (3) interview. Each test was given two questions that meet the criteria for critical thinking behavior with the theme of coffee. The test is given at the end of mathematics lessons every Monday. Observations focused on three critical thinking behaviors, namely truth-seeking, open-mindedness, and inquisitiveness. Interviews were conducted at the end of the activity, namely after five learning meetings.  There are two findings in this research. First, junior high school students around coffee plantations are accustomed to truth-seeking, open-mindedness, and inquisitiveness in responding to questions from teachers. The habit of students in responding to teacher questions begins at the third meeting in learning. Second, there are three types of questions that can provoke students to behave critically. The three types of questions are questions that require students to construct concepts, principles, and procedures.Soal-soal yang diberikan oleh guru selama pembelajaran di kelas mempengaruhi proses berpikir siswa. Sehingga perlu dilakukan penelitian yang bertujuan untuk mendeskripsikan jenis pertanyaan apa yang dapat menstimulus siswa untuk berperilaku kritis. Subjek penelitian adalah 40 siswa SMP di sekitar perkebunan kopi di Jember, Indonesia. Metode pengumpulan data pada penelitian ini adalah (1) metode tes, (2) metode observasi, dan (3) metode wawancara. Setiap tes diberikan dua soal yang memenuhi kriteria perilaku berpikir kritis dengan tema kopi. Soal yang diajukan merupakan soal yang menitikberatkan pada konstruksi konsep, prinsip, dan prosedur dalam matematika. Tes diberikan pada akhir pelajaran matematika setiap hari Senin. Pengamatan difokuskan pada tiga perilaku berpikir kritis, yaitu pencarian kebenaran, keterbukaan pikiran, dan rasa ingin tahu. Wawancara dilakukan pada akhir kegiatan yaitu setelah lima kali pertemuan pembelajaran. Ada dua temuan dalam penelitian ini. Pertama, siswa SMP di sekitar perkebunan kopi terbiasa mencari kebenaran, memiliki pemikiran terbuka, dan rasa ingih tahu dalam menjawab pertanyaan dari guru. Kebiasaan siswa dalam menanggapi pertanyaan guru dimulai pada pertemuan ketiga dalam pembelajaran. Kedua, ada tiga macam soal yang dapat menstimulus siswa untuk berperilaku kritis. Ketiga jenis soal tersebut merupakan soal yang menuntut siswa untuk menyusun konsep, prinsip, dan prosedur.

Abstract

This study aimed at investigating the relationship between student’s algebraic thinking and cognitive style of Field Independent (FI) and Field Dependent (FD). The method implemented in the study is Group Embedded Figure Test (GEFT) which was intended to categorize students into the FI and FD styles. Afterward, to collect the data of students’ algebra thinking ability, a test was administered. The result of the test was compared to the result of GEFT test by integrating a computer program to find out the relationship between the students’ algebraic thinking and their cognitive styles, both FD and FI. The subjects of this research were the eighth-grade students totaling at 24 students. The findings of this study indicate that there is no relationship between manipulating symbols and students’ cognitive style.. There is a relationship between generalizing and formalizing and stundents’ cognitive styles. There is a relationship between using algebra as a tool and FD. There is a relationship between reasoning and representation and student’s cognitive style.
