Abstract

The information and communication technology (ICT) has been used as amedium of learning. The conventional method is still monotonous and rigid.Therefore, students and lecturer can take advantage of e-learning in the learningprocess. Hence, this study in the course of English for Mathematics aims todevelop teaching materials with an integration of ICT: online discussions,learning videos, access to online materials, and online quiz. The findings showthat the instructional videos that were developed by lecturers were easy to deliverto the students by this e-learning process. The students might watch the videobefore the class then discuss and share the new knowledge in discussion forum.Furthermore, this ICT based learning facilitated the lecturers to assess students’online activities: like forum discussions, exercises, and developed quiz withoutbeing limited by space and time.

Abstract

Translation of representations is a process of changing representations from one into another one. In generally, mathematics representations consists of symbolical, visual (graphical), verbal, and tabular representations. This article discusses results of research about teacher’s understanding of mathematics representations and its implementation, which is teacher’s ability of translating from symbolical representation to graphical representation and vice versa. The sample of research were 91 mathematics teacher from some districts of South Sumatera and Bangka Belitung provinces. The data of research were collected by test related to addition of integers. The results show that teacher’s ability of translating from symbolical representation into graphical representation is very low which is only 48,4% of the sample could translate the representations correctly, meanwhile teacher’s ability of translating from graphical representation into symbolical representation is quite good which is 75,8% of the sample could translate the representations correctly. The mistakes identified when the mathematics teachers translated symbolic representation to visual representation are the result of addition not presented in numbers line, no the result of addition presented at all,  the order of numbers line not presented clearly, misdirection or no direction of numbers line, and no answers at all. Meanwhile the mistakes identified when the mathematics teachers translated visual representation to symbolic representation are no the result of addition presented, incorrectly order of numbers added, and no answers at all.

Abstract

The development of the PISA framework from year to year is increasingly focused on problem solving. This indicates that problem-solving ability is crucial. Considerable studies at the international level on the influence of PISA implies that the world also indirectly focuses on problem-solving abilities. The National Council of Teachers of Mathematics (NCTM) mentions five basic mathematical skills, one of which is problem solving. Mathematical modeling is one of the stages of mathematical problem solving. For that, mathematical modeling problems are chosen so that student can train problem solving ability. This study aims to describe problem solving ability of junior high school students in solving mathematical modeling problems. The result of mathematics problem solving test in grade VII students at SMP Negeri 1 Palembang has three categories, that is students with problem solving ability of mathematical well, enough, and less. The lowest occurrence of the problem solving indicator is the first indicator that is to explore and understand mathematics problems.

Abstract

Mathematics can be represented by many forms such as symbolical, verbal, graphical, or tabular representations. To understand mathematics concepts is by connecting or translating all kind of mathematics representations. Therefore, mathematics teachers should facilitate students to translation all kind of mathematics representations. This article discusses the research results which investigated how mathematics teachers implement their teaching which facilitate students to translation mathematics representations. Data were collected by questionnaire, documentation, and observation. Sample of the research were 91 mathematics teachers of junior and senior high schools from some regions of South Sumatera and Bangka Belitung. The research results show that mathematics teachers have already implemented mathematics representation properly, however representations used by the teachers were not variably, which means translations between representations were not implemented yet. By comparing all mathematics representations, the symbolical representation was the most frequently used in teaching and learning. Mathematics teachers whom did not or poorly implemented mathematics representations in their teaching considered the national examination not requiring variation of the representations.

Abstract

Tujuan pembelajaran matematika adalah untuk melatih siswa berpikir kritis. Oleh karena itu, perlu dikembangkan Lembar Kerja Siswa (LKS) untuk melatih kemampuan berpikir kritis siswa. Penelitian ini bertujuan untuk menghasilkan LKS yang berkarakteristik untuk melatih kemampuan berpikir kritis siswa kelas VII SMP. Sampel pada penelitian ini adalah kelas VII7 berjumlah 30 siswa semester II SMP Negeri 9 Palembang. Metode penelitian yang digunakan adalah metode penelitian pengembangan yang terdiri dari analisis, desain, evaluasi dan revisi. Pengumpulan data dilakukan dengan cara prototyping. Prototyping dilakukan untuk mengetahui bagaimana karakteristik LKS untuk melatih kemampuan berpikir kritis siswa kelas VII SMP. Hasil penelitian ini adalah karakteristik LKS untuk melatih kemampuan berpikir kritis siswa kelas VII SMP. Kata kunci: Kemampuan berpikir kritis, Lembar Kerja Siswa Mathematics learning aims to develop students’ critical thinking.

Abstract

The rapid development of technology must be utilized as well as possible, especially in the world of education, because education is the basis for forming individuals who are strong and able to compete in facing the challenges of the times. The habit of students using existing formulas without knowing the concept of the material causes them to have difficulty solving the same problem but in a different form of problem. Therefore, the development of electronic student worksheets based on Rigorous Mathematical Thinking (RMT) on the material of rows and series becomes an electronic teaching material that contains the stages of the learning process to build an in-depth understanding of the concepts of students as well as being one of the changes from existing technological developments. This study aimed to assess the validity and practicality of electronic student worksheets based on RMT developed. The research method used is Research and Development (R&D) with the 4D development model. The validity and practicality assessment instrument is a student questionnaire sheet with a Likert scale. The data obtained were analyzed using the percentage of the assessment score. The validation results show that electronic student worksheets are categorized as valid, with an average percentage of material validation of 88.13%, an average percentage of media validation of 94.62%, and an average percentage of language validation 93.64%. The practicality test obtained an average percentage of 78.39% in the practical category.
