Mathematics education during these years has a significant effect on children's future lives. Play is a significant issue in children's lives and can be used as a way for teaching and learning. It presents a rich learning environment. In this study, therefore, we mainly focused on which mathematical concepts, skills and play types children preferred and found out mathematical concepts and skills observed in various play types children preferred while they were playing. This study was a qualitative study and 15 children from different age groups participated. The results of this study indicated that measurement related skills and number related skills were frequently used and pretend play and object play types were used mainly by children. Besides, pretend play and object play types were frequently used by children while they were using measurement and number related skills.

Simetri kavramı matematik içerisinde önemli bir yere sahip olup geometri, olasılık, problem çözme, cebir gibi alanlar arasında bağlantı kurmada etkilidir. Simetri kavramı okul öncesi dönemde üzerinde durulan bir kavram olmamasına rağmen eş olma ve eşleme becerisi önemli bir yere sahiptir. Bu açıdan bu çalışmanın amacı, okul öncesi öğretmenleri ve adaylarının simetriye ilişkin algılarının belirlenmesidir. Bu araştırma nitel araştırma yöntemlerinden durum çalışmasına uygun olarak gerçekleştirilmiş olup, kolay ulaşılabilir örneklem seçme yöntemi ile katılımcılar çalışmaya dâhil edilmiştir. Çalışmada 14 okul öncesi öğretmeni ile 62 öğretmen adayı yer almıştır. Veri toplamak için araştırmacıların hazırladığı yarı yapılandırılmış görüşme formu kullanılmıştır. Görüşme formunun içeriğinde katılımcılardan simetri kavramını çizerek ve yazarak anlatmaları ve simetri kavramını içeren bir hikâye yazmaları istenmiştir. Veriler, içerik analizi yöntemine uygun olarak değerlendirilmiştir. Araştırmanın bulguları katılımcıların simetri kavramına ilişkin sınırlı bilgi birikimine sahip olduğunu göstermiştir. Katılımcıların simetriye ilişkin gösterimlerinde genellikle dikey simetriyi kullandıkları ve simetri türü olarak da yansıma simetrisini kullandıkları tespit edilmiştir.

Methods: In this quantitative study, a figural and a written pattern related to daily life with the same mathematical structure were presented to participants and they were asked to write as many problems as they could. The problems were analyzed based on whether they were viable and then on the components of fluency, flexibility, and originality of creativity. Results: The results of the study indicated that, although the flexibility and originality scores in the figural pattern were higher, the only statistical difference was observed in the originality component. Moreover, it has been found that some of the participants wrote similar problems in both tasks; however, the problems in the figural pattern were inclined to be more difficult. Discussion: Developing students' creative-thinking skills is a main purpose of mathematics education research (Mann, 2006). However, the results of the research have indicated that the teachers' knowledge of how to develop students' creative-thinking skills is still lacking (Shriki & Lavy, 2012) and, consequently, students are provided with few opportunities to experience creative thinking and learning in class (Silver, 1997; Sriraman, 2005). Problem posing has a close association with creativity as well as with problem solving (Haylock, 1997; Silver, 1997). Therefore, to develop creative-thinking skills, learning environments should be enriched with problem-posing tasks. The results of this research do not assert that only one of the figural or written pattern types must be preferred to stimulate creative-thinking skills in the context of problem posing.

Considering the education given during the pre-school period, story books are one of the valuable educational materials for their growth in cognition. From this perspective, the purpose of this study is to investigate mathematical expressions in story books that are appropriate for pre-schoolers. This study followed qualitative approaches. In this study, story books were investigated with respect to the mathematical concepts and abilities found in national early childhood education curriculum. Randomly selected 30 story books were analyzed with documentary analysis method. Data were collected from the story books, each of which was reviewed by at least two researchers. The results indicated that story books generally concentrate on counting, spatial perception and time among mathematical concepts and abilities. On the other hand, patterns, operations (addition and subtraction), and graph are most rarely seen concepts in these books. Especially mathematical expressions related to problem solving skills highly emphasized in primary and secondary school curricula were not significantly observed in the story books investigated. Keywords: Early childhood education, mathematical elements, story books.

This research explored pre-service teachers’ unforgettable mathematics experiences and how these experiences were related to their beliefs about preparing an unforgettable mathematics lesson. This is a case study with conveniently selected participants. Among the participants’ previous mathematics experiences, four categories were delineated: teacher, student, material, and method-related issues, although the most common findings were related to their teachers. Regarding beliefs, participants’ beliefs are presented within these categories (teacher, student, material, and method-related beliefs) as well as learning environment related beliefs are also found. In addition, McLeod [McLeod, D. B. (1992). Research on affect in mathematics education: A reconceptualization. In D. A. Grouws (Ed.), Handbook of research on mathematics teaching and learning (pp. 575–596). Macmillan] categories for beliefs are also considered in the study. However, none of the participants’ beliefs are found to be under McLeod’s category of ‘beliefs about math.’ Therefore, findings indicated that there are both common and conflicting categories and themes with respect to McLeod’s categories.

Öğrencileri bu etkinliğe katılma fırsatından yoksun bırakırsanız -kendi problemlerini kurmaktan, kendi varsayımlarını ve keşiflerini yapmaktan, hata yapmaktan, yaratıcı bir şekilde hayal kırıklığına uğramaktan, ilhamalmaktan ve kendi açıklamalarını ve kanıtlarını bir araya getirmekten- matematiğin kendisinden yoksun bırakırsınız." Paul Lockhart, A Mathematician`s Lament Lockhart`ın matematik eğitimine ilişkin bu görüşlerinden hareketle erkençocukluk dönemi (3-8 yaş) matematik eğitimini ele alan bu kitapta teorik bilgininyanı sıra sınıfta kullanılmak üzere önerilebilecek konuyla bağlantılı etkinlik örneklerine,çocuk kitaplarına ve teknolojik bağlantılara yer verilmiştir. Kitabın, erken çocukluk dönemi matematik eğitimi alanında çalışmalar yapan bilim insanlarına,okul öncesi eğitimi, sınıf ve matematik öğretmen adayları ve öğretmenlerine, matematik eğitimi için çocuklarına destek olmak isteyen anne ve babalara katkı sunmasını umut ediyoruz.
