Abstract

This study aims to develop a contextual mathematics learning video based on semiotics that supports learning from home. This type of research is development research using a 4-D model, which is modified into three stages, namely define, design, and develop. The research subjects were grade 6th elementary school students in Tuban, East Java. In the defined stage, a needs analysis is carried out as a reference for development. The design stage produces research instruments and instructional video designs. The development stage states that based on the results of the validation of media experts by 85% and material experts by 87%, each of which comes from 21 points of assessment indicators, it shows that it meets the valid criteria as well as positive responses of 85.3% of 28 students. The right-hand t-test obtained t-count t-table, namely 3.886 1.675. It indicates that the learning outcomes of students who use semiotic-based contextual mathematics learning videos on the perimeter of circle material are better than students who do not use them. This learning video has reached effective criteria.

Abstract

This study describes the profile of vocational high school students' metacognitive abilities in mathematics problem solving based on their logical thinking abilities. This research was conducted using descriptive research methods with a qualitative approach. The data was collected using a logical thinking ability test and problem-solving test and. Three students were selected who met different logical thinking stages: the abstract operation stage, the transition stage, and the concrete operational stage. The results showed the subject of the abstract operation stage fulfilled the metacognition stage by re-describing the given problem, knowing the relationship between what was known and what was asked, working on the problem by writing down what was known and asked and entering into the formula and also checking the answer. Transition stage subjects fulfill the metacognition stage by describing initial information and instructions, performing problem-solving steps, and counting to check completed work. The subject of concrete operations fulfills the metacognition stage by stating information and instructions that are non-specific and detailed. The subject has not been able to state the proper steps to ensure the information's conformity with the problem, and the subject sees what is done by calculating.

Abstract

This article describes a generalization strategy on pictorial visual patterns. This explorative descriptive study involves 60 students of 7 Grade Student of private junior high school in Tuban East Java Indonesia. Data obtained through the pattern generalization task. The type of pattern used in this research is pictorial sequences with two non-consecutive terms. Selection of a pictorial sequences with two non-consecutive pattern to focus students' attention on visual stimuli. Based on the students answers of pattern generalization task, there are 33 students who answered correctly and 27 students answered wrong. From the correct answer, there are six different general formula representations. The visualization strategy used by the students begins by splitting the image into smaller elements. The way students break down into smaller elements is also diverse. Students divide the image in the form of V (2 matchsticks), U shape (3 matchsticks), square shape (4 matchsticks) and lastly divide in a unit additive consisting of 7 matchsticks.

Abstract

The ability to prove formal mathematics is an important ability that must be mastered by undergraduate prospective mathematics teachers. However, students who are prospective mathematics teachers have difficulty in constructing proof in mathematics courses. Therefore, this study aims to explore the tendency of mathematical proof methods for prospective mathematics teachers in second year lectures. The method used in this research is quantitative descriptive research. Participants in this study were 30 prospective mathematics teachers at a tertiary institution in Tuban, East Java. The research instrument is a simple task of compiling mathematical evidence. The results of the study were analyzed using the classification of types of proof by Miyazaki, namely classifying the types of deductive and inductive reasoning. The results showed that prospective mathematics teachers had a greater tendency to use deductive reasoning than using inductive reasoning. Type A proof is the most common type of proof. In addition, around 70% of prospective teachers still experience difficulties in compiling evidentiary tasks.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan proses generalisasi berdasarkan perspektif semiotik pada siswa operasional konkret dan operasional formal. Material semiotik yang akan dianalisis meliputi, gestur, ucapan dan tulisan. Penelitian kualitatif eksploratif ini dilaksanakan di salah satu SMP swasta  di Tuban Jawa Timur Indonesia. Subjek dalam penelitian ini adalah seorang siswa Kelas VII yang berada pada tahap operasional konkret dan operasional formal. Subjek dipilih dengan menggunakan instrument GALT (Group of Assessment of Logical Thinking). Data dikumpulkan dengan think aloud, yaitu saat menyelesaikan tugas generalisasi pola, siswa menyatakan proses berpikirnya secara lisan. Selain itu, juga dilakukan wawancara. Data yang telah terkumpul kemudian dianalisis dengan menggunakan teknik analisis data kualitatif. Hasil penelitian menunjukkan bahwa siswa operasional konkret melalui tiga tahapan proses generalisasi, sedangkan siswa operasional formal melalui empat tahapan proses generalisasi. Tahapan membuktikan kebenaran rumus umum tidak dilakukan oleh siswa operasional konkret. Siswa operasional konkret menyatakan produk generalisasi dalam bentuk kalimat sederhana berdasarkan pada konteks gambar yang dilihat, sedangkan siswa operasional formal menyatakan produk generalisasi dalam bentuk aljabar simbolik.
