7. Sınıf Öğrencilerinin Kesirlerde Toplama İşlemine Kurdukları Problemlerin Analizi

Öz

Araştırmada, ilköğretim yedinci sınıf öğrencilerinin kesirlerde toplama işlemine yönelik kurdukları problemlerde karşılaşabilecekleri olası güçlüklerin belirlenmesi amaçlanmıştır. Araştırma, Erzurum merkezdeki yedi ilköğretim okulunun yedinci sınıflarında öğrenim gören 210 öğrenci ile yapılmıştır. Kesirlerde toplama işlemine yönelik beş maddeden oluşan Problem Kurma Testi (PKT) veri toplama aracı olarak kullanılmıştır. Öğrencilerin kurdukları problemlerde; toplanan ikinci kesri bütünün kalanı üzerinden ifade etme, parça-bütün ilişkisini kuramama, işlem sonucuna doğal sayı anlamı yükleme, birim kargaşası, toplanan kesir sayılarına doğal sayı anlamı yükleme, işlemi soru köküne yansıtamama ve tamsayılı kesirlerin tam kısımlarına anlam yükleyememe şeklinde yedi güçlük tespit edilmiştir. En fazla güçlük sonucun tamsayılı kesir olduğu iki basit kesrin toplamına, en az güçlük ise sonucun basit kesir olduğu iki basit kesrin toplamına yönelik problem kurmada görülmüştür.

Anahtar Kelimeler

• Problem kurma, kesirler, kesirlerde toplama işlemi

Analyzing Problems Posed by 7th Grade Students for Addition Operation with Fractions

Abstract

The aim of the present study was to determine the potential difficulties which might be experienced by elementary school 7th grade students related to the problems posed by them on addition operation with fractions. The study was conducted with 210 students studying at seven elementary schools located in Erzurum city center. The Problem Posing Test consisted of five items related to addition operation with fractions was used as the data collection tool. Seven difficulties were determined in the problems posed by the students. The most significant difficulty was observed in posing problems requiring addition of two simple fractions to produce a fraction with integer, while the least significant one was experienced in posing problems requiring addition of two simple fractions to produce a simple fraction.

Keywords

• Problem posing,fractions,addition operation with fractions.
