ANALISIS KEMAMPUAN MAHASISWA PENDIDIKAN GURU SEKOLAH DASAR FKIP UNIVERSITAS RIAU DALAM PENGUKURAN KELILING DAN LUAS BANGUN DATAR

The purpose of this study is to analyze student teachers at Primary School Teacher Education of RiauUniversity in understanding the concepts of measurement perimeter and area. The reason in doingthis research is that many student teachers usually use formal formula in solving measurementperimeter and area. They will do the same thing when they teach Primary School Students, so thestudents will not know how the formula works. Design research was chosen as a method in gettingdata. The data were collected from 48 student teachers at Primary School Teacher Education of RiauUniversity. The result showed that six out of ten group of student teachers did not use partitioning inthe beginning of the lesson. They also made a mistake in measuring the perimeter of unstructuredshapes. After classroom discussion, 96% student teachers came to the idea of partitioning. It meansthat they realized the important of partitioning in measure the area of unstructured shapes. Key words: measurement perimeter and area, design research, partitioning, and unstructured shape

A framework for a comparative study of pre-service elementary teachers’ knowledge of rational numbers

This paper presents a framework of a PhD research of the first author about a comparative study of pre-service elementary teachers’ knowledge of rational numbers between Indonesia and Denmark. To obtain the data, the authors design a series of hypothetical teacher tasks (HTTs), inspired by a paper of Durand-Guerrier, Winsløw, and Yoshida (2010). Subjects in this research are pre-service elementary teachers from a selection of different University Colleges in Denmark and from the elementary school teacher education study program, Riau University, in Indonesia. The praxeological reference models and the levels of didactic codetermination are used as tools to analyse the result

Prospective Elementary Teachers’ Knowledge of Comparing Decimals

The aim of this study is to investigate prospective elementary teachers’ (PsETs) mathematical and didactical knowledge of comparing decimals. Thirty-two fourth-year PsETs from an elementary school teacher education study program in Indonesia participated in this study. Each PsET is asked to solve a mathematical task of comparing decimals presented in the hypothetical teacher task (HTT), and then the PsETs use their mathematical knowledge to build their didactical knowledge collectively (pairs). Their mathematical and didactic knowledge is analyzed based on the anthropological theory of the didactic, especially praxeology. The findings indicate that PsETs have various techniques to solve the comparing decimal task, but some of them find it difficult to explain those techniques

KETERAMPILAN DASAR MENGAJAR GURU PADA PROSES PEMBELAJARAN MATEMATIKA DI KELAS V SDN 110 PEKANBARU

BASIC TEACHING SKILLS FOR TEACHERS IN THE MATHEMATICS LEARNING PROCESS IN CLASS V ELEMENTARY SCHOOL 110 PEKANBARUThis study aims to describe teachers basic teaching skills in mathematics learning process of fifth grade students in SDN 110 Pekanbaru. This is a qualitative study conducting in in the even semester of 2019/2020. The subjects of this study were two fifth grade teachers. Teachers basic teaching skills were investigated based on four skills, namely asking questions, providing reinforcement, varying learning activities, and guiding small groups and individuals. The results of this study showed that both teachers have sufficient basic teaching skills in mathematics learning process. The teachers performed very well on guiding small groups and individuals comparing to the other skills
