Abstract

This aims of this study are to know the role of Museum Timah Indonesia Pangkalpinang context as alternative  to understanding angles. This studi was using design research using Hypothetical Learning Trajectory (HLT) where research is conducted in three stages, namely initial design, teaching experiment (the pilot experiment) and retrospective analysis.this research was conducted at SD Negeri 29 Pangkalpinang. The data were collected through several things, namely by pre test and post test, video recording, collecting student work, interviews, and field notes. The results indicated that with the context of Museum Timah Indonesia Pangkalpinang, students could understand angle measurement. Students are more interested and motivated in completing angular measurements so that learning is more meaningful. PMRI can be used as an approach to learning angular measurements in elementary schools.

Abstract

Mathematics is a universal science that underlies the development of modern technology that has an important role in various scientific disciplines and advances human thinking power. One of the achievements of Indonesian students in the field of mathematics, can be seen based on the 2011 TIMSS ranking in which Indonesia ranked 38th of 42 participating countries. One of the factors that causes the low TIMSS results is because the TIMSS model questions in its lesson that have moderate and high complexity, and require reasoning in the completion process. Therefore, researchers were interested in developing mathematical question with TIMSS model in the fourth grade of elementary school. The development of these questions was done through two stages, namely the preliminary study stage, the preparation stage and the formative evaluation stage which included self-evaluation, prototyping (expert reviews, one to one, and small group), and the test field. In this study, there were ten questions categorized as valid and practical qualitatively and quantitatively.

Abstract

Mathematics is one of the subjects that spearheads in other subjects. Mathematics is studied starting from elementary school to equip students with the ability to logically thought, analytically, systematically, critically, creatively, and the ability to work together. The sequential stages of aspects in mathematics are numbers, geometry and measurement and data processing. From the stages of the aspects mentioned it appears that the subject matter of numbers is the initial stage that must be mastered in mathematics. Numbers are the basic subjects that are very important for students to understand because they are the basic for other subjects. Integers is one of the mathematic subject. For this reason, this study aims to develop teaching materials in the form of student worksheet integer operation material for elementary school students. This research is the initial stage of development research. The subjectsof research were fourth grade students of elementary schools number 42 Pangkalpinang. The process of developing needs analysis teaching materials, modules are developed on concepts that are still not mastered by students, planning of unknow concepts by students, and developed to determine SK, basic competencies, indicators, syllabus, lesson plans, determining student worksheet elements, collect to material, prepare student worksheet drafts, and validate. From the design of this prototype produced the first prototype of the integer operation student worksheet for fourth grade elementary school students.

Abstract

Difficulty in understanding the concept of angle because of learning of angle is only explain, give examples, and practice, so there are still many students who have difficulty understanding the concept of angle. Angle is one of the most basic concepts to understanding geometry and should have been understood and mastered since elementary school in terms of length and angle so as not to cause students difficulties in learning angles in high school. PMRI was chosen because it can lead students to understand mathematical concepts, which in this study is the concept of angles. The aims of this study is to design a hypothetical learning trajectory in angle by using context of the Museum Timah Pangkalpinang as a tool in understanding the concept of angles. This study was using design research approach, with three stages of research are preparing for the experiment, the experimental design, retrospective analysis. The Hypothetical Learning Trajectory (HLT) was developed from a series of corner material learning activities using context of the Museum Timah Pangkalpinang. HLT is generated with 4 activities, that are observe museum buildings and mining equipment,determine the types of angle, determine the angle using the steps outlined in LKPD, and completed the questions.Keywords: Angle, Museum Timah, PMRI, HLT
