  Examination of Sixth Grade Students’ Problem-Posing Skills: A Case Study

  Öztürk, Mesut; Demir, Fatih; Ada, Kübra

  The aim of this study is to examine the sixth grade students' skills in different problem situations requiring four operations in natural numbers and their views on problem posing. Participants of this study, where case study of qualitative research methods were preferred, consisted of 15 students studying at sixth grade level In the study, a problem-posing test including different problem-posing situations, and a semi-structured interview form related to basic operations in natural numbers, were used as data collection tools. Problem posing test consisted of 10 questions. The semi-structured interview form includes open-ended questions on students' mathematical problems and thoughts on problem solving.. The data obtained from the problem-posing test were analyzed with regard to the rubric of the test.. The answers were first classified as “empty”, “not a problem” and “problem”. Afterwards the answers determined to be a problem were evaluated and analyzed according to the criteria of “language”, “complexity of the problem” and “solvability” in the rubric put forward by Ada and Öztürk (2019). The data obtained from the interviews with the students were analyzed by descriptive analysis. According to the results of the study, while some of the students left the questions blank, a larger part of them could not form a problem sentence even though they answered the questions. In addition, a number of errors were identified in the students' perception of the problem concept. While students were able to pose problems in the most selection cases, they were able to pose very few problems in case of free problems. When the findings of the students' views are considered within the scope of the study, it is determined that problem-posing helps to understand the problem from a cognitive point of view and contributes to the meaning of procedural expression or mathematical subject. At the same time, it has been found that problem-posing creates positive attitudes in students by reducing prejudice against problems in terms of affective aspects and affects students' attitudes towards mathematics and brings them closer to the lesson. In line with the results of the study, some suggestions were made to the research and education stakeholders.

  İlköğretim Matematik Öğretmeni Adaylarının Örüntüleri Genelleme Süreçleri: Stratejiler ve Gerekçelendirmeler1

  Öztürk, Mesut; Akkan, Yaşar; Akkan, Pınar

  Bu çalışmanın amacı, ilköğretim matematik öğretmeni adaylarının farklı örüntü problemleri ile ilgili genelleme stratejilerini incelemek, genellemelerinin altında yatan gerekçelendirmeleri keşfetmek ve genelleme ile gerekçelendirmeleri arasındaki ilişkileri belirlemektir. Çalışma nitel araştırma desenlerinden olgubilim modeline göre tasarlanmıştır. Çalışma, Doğu Karadeniz Bölgesindeki bir üniversitenin İlköğretim Matematik Öğretmenliği programında öğrenim gören 4. sınıf öğretmen adayları ile yürütülmüştür. Veri toplama araçları, hem literatür hem de öğretim üyesi desteğiyle hazırlanan ve farklı çözüm stratejilerinin ve gerekçelendirme çeşitlerinin üretilebildiği lineer ve kuadratik örüntü problemleridir. Mülakatlar sonucu toplanan veriler araştırmanın kavramsal çerçevesi dâhilinde betimsel analiz tekniği kullanılarak çözümlenmiştir. Elde edilen sonuçlardan, öğretmen adaylarının en yaygın kullandığı strateji türü fonksiyonel strateji olmakla birlikte, içeriksel, yinelemeli, tahmin-kontrol ve karma stratejileri de kullanmışlardır. Öğretmen adaylarının çoğu gerekçelendirmelerini sayısal kontrol yoluyla doğrulama ile yapmışken, açıklama ve dışsal bilgi kaynağı yoluyla gerekçelendirme yapan öğretmen adayları da tespit edilmiştir

  Determining the Teacher Candidates Perceptions on Distance Education by Metaphors

  Güven, Bülent; Yılmaz, Gül Kalelı

  The aim of this study is to determine teachers candidates perceptions on distance education via metaphors. The sample consisted of 150 teacher candidates drawn from departments of science teacher and primary teacher at Faculty of Education in Bayburt University. 70 of the sample are primary teacher candidates that attended courses via distance education in their undergraduate programme. 80 of them are science teacher candidates that took distance education elective course. To collect the data the teacher candidates were asked to complete this sentence: Distance education is like......because.... . Data was analysed by using content analysis technique one of the qualitative data analysis methods. The results indicate that the teacher candidates metaphors referred to such different issues as need-aimed, variety, arbitrary, requirement. Moreover, when the findings are searched, it was determined that the primary teacher candidates take lesson by means of synchron distance education have more negative perception in contrast with science teacher candidates. It was noticed that some factors such as carrying out the synchron distance lessons as 90 min blocks, no chance to ask any question to the teacher out of the lesson time, occasionally encountering technical problems in the lesson causes the negative perception. To develop positive perception about synchron distance education, it is suggested that some distance education conditions which allows communication between students and teachers out of the lesson time should be designed as minimising the technical problems and informing to the participants about distance education applications.
