This study was designed to compare the effects of Team Assisted Individualization (TAI) and Student Teams-Achievement Divisions (STAD) on fourth grade students' academic achievement in and attitudes towards mathematics. Seven classes of a school were randomly selected for this experimental study. Two of these were given instruction through TAI; two through STAD, and the remaining three were treated as a control group. For the purpose of the data analysis regarding academic achievement, the 3X1 covariance analysis was used to compare the groups. As a result of this comparison, both the TAI and STAD methods were found to have positive effects (d=1.003 for TAI and d=0.40 for STAD) on students' academic achievement in mathematics. The pairwise comparisons showed that the TAI method had a more significant effect than the STAD method. The scores for the attitude towards mathematics were analyzed by using non-parametric statistics. As a result of this analysis, no significant difference was observed regarding students' attitudes towards mathematics.

The aim of this study is to investigate the efficiency of cooperative learning on preschoolers' verbal mathematics problem-solving abilities and to present the observational findings of the related processes and the teachers' perspectives about the application of the program. Two experimental groups and one control group participated in the study. Results found that preschoolers in the experimental groups experienced larger improvements in their problem-solving abilities than those in the control group. Findings also revealed that the cooperative learning method can be successfully applied in teaching verbal mathematics problem-solving skills during the preschool period. The preschoolers' skills regarding cooperation, sharing, listening to the speaker and fulfilling individual responsibilities in group work improved. The teachers' points of view also supported these findings.

This study aims to investigate primary school students' addition and subtraction based mathematical word problem solving levels and to identify the types of questions asked to students in mathematics course books. A form with problem types was administered to 158 third year students. Also, 6 mathematics course books and students' books were analyzed through document analysis. The results showed students had difficulties in initial unknown addition and subtraction problems and compare problems. In addition, it was found out that result unknown addition and subtraction based word problems were mostly used in the mathematics course books and students' books prepared by the Ministry of National Education. It was also observed that compare problems were very scarcely used.

Bu çalışmanın amacı, sınıf öğretmeni adaylarının matematik ve matematik öğretimi yönelik algılarını metaforlar aracılığıyla incelemektir. Araştırmanın modeli, nitel araştırma desenlerinden olgubilim deseninde bir çalışmadır. Araştırmaya, 2016-2017 akademik yılında bir devlet üniversitesinin Sınıf Eğitimi Anabilim Dalında öğrenim görmekte olan 73 üçüncü sınıf öğrencisi katılmıştır. Öğretmen adaylarından "Bana göre matematik …… gibidir." Çünkü; "…..." ve "Bana göre matematik öğretimi …… gibidir." Çünkü; "..….." cümleleri yöneltilerek matematik ile matematik öğretimi hakkında bir metafor geliştirmeleri ve gerekçelerini açıklamaları istenmiştir. Araştırmanın verilerinin analizinde içerik analizi yöntemi kullanılmıştır. Elde edilen sonuçlara göre, matematik kavramına yönelik "hayat, zekâ küpü, oyun, bulmaca, bilgisayar" metaforlarının sıklıkla kullanıldığı belirlenmiştir. Matematik kavramına ait metaforlar analiz edildiğinde; öğretmen adaylarının matematik kavramına ilişkin algılarında "süreç" ve "gereklilik" temaları öne çıkmaktadır. Matematik öğretimi kavramına yönelik ise "oyun, labirent, makine" metaforlarının sıklıkla kullanıldığı belirlenmiştir. Matematik öğretimi kavramına ait metaforlar analiz edildiğinde; öğretmen adaylarının matematik öğretimi kavramına ilişkin algılarında ise "altyapı/kaynak", "gereksinim/vazgeçilmezlik" ve "emek/çaba" temaları öne çıkmaktadır.
