Abstract

At the end of primary school all children more of less know what a percentage is, but yet they often struggle with percentage problems. This article describes a study in which students of 13 and 14 years old were given a written test with percentage problems and a week later were interviewed about the way they solved some of these problems. In a teaching experiment the students were then taught the use of the percentage bar. Although the teaching experiment was very short - just one lesson  -  the results confirm that the percentage bar is a powerful model that deserves a central place in the teaching of percentages.

Abstract

Indonesia's involvement in the Programme for International Student Assessment (PISA) is one attempt to see how far the development of educational programs in our country compared to other countries in the world. PISA results show that Indonesia is still at the lower level. This means that the ability of Indonesian students in solving problems that require the ability to review, giving reasons and communicating effectively, and solve and interpret problems in various situations is still lacking. This may be due to government policy in the presence of the National Examination (UN) in which the spread of the UN's questions are still at the lower levels of cognitive aspects that are not in line with government regulations on curriculum which suggests that the fulfillment of cognitive aspects as one of the important aspects of education. To that end, researcher conducted a study that aims to produce valid and practical the sixth level of PISA-like mathematics problems for middle school students. This study is the development research formative evaluation type. The research subjects are ninth grade students SMP Negeri 1 Palembang. Data collection techniques used are walkthrough, documentation, interviews, and tests. From the analysis it can be concluded that this research has resulted a product the sixth level of PISA-like mathematics problems. At the stage of expert review, an expert and two colleagues evaluated the problems from different aspects. Trying out at one-to-one and small group wasperformed on students with different mathematical abilities. Then at the field test stage, 26 students in one class answered the questions that were developed.

Abstract

Understanding of measuring time has difficulty for children because it is intangible. Standar units often use directly by teacher for learning time measurement. Many researches involved game in designing learning material to facilitate fun and meaningful learning for children. For this reason, learning of time measurement that connect with children's daily experience was designed. The context of this research was traditional gasing game. The study is situated in implementation of Indonesian version of Realistic Mathematics Education, labeled as PMRI. This research aimed acquire learning trajectory of time measurement using traditional gasing game for the third grader of primary school by describing students' progress in learning. Design research methodology comprising preparing for the experiment, teaching experiment, and retrospective analysis was used. The research was conducted in SD (Sekolah Dasar) Pusri (Pupuk Sriwijaya) Palembang as one of PMRI (Pendidikan Matematika Realistik Indonesia) school. The result of the teaching experiment showed that learning design could foster students to experience reinvention of time measurement historically. It stimulated students to emerge their sense of time, measure time using non standar unit, understand the concept of standard unit, and measure time using standar unit. Students' strategies that were emerged showed students' progress through situation and problems that were provided by traditional gasing game.

Abstract

The chart of Indonesian student of mathematical ability development in Program for International Student Assessment (PISA) event during the last 4 periods shows an unstable movement. PISA aims to examine the ability of children aged 15 years in reading literacy, mathematics literacy, and science literacy. The concept of mathematical literacy is closely related to several other concepts discussed in mathematics education. The most important is mathematical modelling and its component processes. Therefore the goal of this research is to investigate secondary school students' difficulties in modeling problems PISA-model level 5 and 6. Qualitative research was used as an appropriate mean to achieve this research goal. This type of research is a greater emphasizing on holistic description, and phenomenon identified to be studied, students' difficulties in modelling real world problem in PISA model question level 5 and 6. 26 grade 9 students of SMPN 1Palembang, 26 grade 9 students of SMPK Frater Xaverius 1 Palembang, and 31 participants of mathematical literacy context event, were involved in this research. The result of investigate showed that student is difficult to; (1) formulating situations mathematically, Such as to representing a situation mathematically, recognizing mathematical structure (including regularities, relationships, and patterns) in problems, (2) evaluating the reasonableness of a mathematical solution in the context of a real-world problem. The students have no problem in solve mathematical problem they have constructed.

Abstract

This paper presents the findings from a posttest experiment control group design by using reciprocal teaching, conducted in Indonesia University of Education to investigate students' ability in mathematical communication and self regulated learning.  The subject of the study were 254 of 9th grade students from three junior high schools of the high, medium, and low level in Bojonegoro, East Java.  The instruments of the study were an essay mathematical communication test, and a self-regulated learning scale. The study found that reciprocal teaching took the best role among school cluster and students' prior mathematics ability on students' mathematical communication ability and self-regulated learning as well.  The other finding was there was an interaction between school cluster and teaching approaches, but was no interaction between students' prior mathematics ability and teaching approaches on mathematical communication ability and self-regulated learning. Moreover, there was an association between mathematical communication and self regulated learning.

Abstract

The students' difficulty which was found is in the problem of understanding, drawing diagrams, reading the charts correctly, conceptual formal mathematical understanding, and mathematical problem-solving. The appropriate problem representation is the basic way in order to understand the problem itself and make a plan to solve it. This research was the experimental classroom design with a pretest-posttest control in order to increase the representation of visual thinking ability on mathematical problem-solving approach with contextual learning. The research instrument was a test, observation, and interviews. Contextual approach increases of mathematical representations ability increases in students with high initial category, medium, and low compared to conventional approaches.

Abstract

Subtraction has two meanings and each meaning leads to the different strategies. The meaning of “taking away something” suggests a direct subtraction, while the meaning of “determining the difference between two numbers” is more likely to be modeled as indirect addition. Many prior researches found that the second meaning and second strategy rarely appeared in the mathematical textbooks and teacher explanations, including in Indonesia. Therefore, this study was conducted to contribute to the development of a local instruction theory for subtraction by designing instructional activities that can facilitate first grade of primary school students to develop a model in solving two digit numbers subtraction. Consequently, design research was chosen as an appropriate approach for achieving the research aim and Realistic Mathematics Education (RME) was used as a guide to design the lesson. This study involved 6 students in the pilot experiment, 31 students in the teaching experiment, and a first grade teacher of SDN 179 Palembang. The result of this study shows that the beads string could bridge students from the contextual problems (taking ginger candies and making grains bracelets) to the use of the empty number line. It also shows that the empty number line could promote students to use different strategies (direct subtraction, indirect addition, and indirect subtraction) in solving subtraction problems. Based on these findings, it is recommended to apply RME in the teaching learning process to make it more meaningful for students.
