- MakaleAçık Erişim2023Matematiksel güven ölçeğinin geliştirilmesi: geçerlik ve güvenirlik çalışması
Öztürk, Mesut; Albayrak, Mustafa; Ada, Kübra
Yapılan araştırmalar matematiksel güveni yüksek olan öğrencilerin genelde matematikte, özelde ise problem çözmede daha başarılı olabileceğini vurgulamıştır. Bu nedenle matematiksel güveni incelemeye yönelik yapılacak araştırmalar önemli görülmektedir. Ancak alan yazın incelendiğinde matematiksel güvene yönelik yapılan çalışmaların uluslararası alan yazında son yıllarda yoğunlaşmaya başladığı, bu yoğunluğun ise ulusal alan yazına yeterince yansımadığı belirlenmiştir. Bu durumun nedeni matematiksel güvene yönelik yapılan araştırmalarda daha çok nicel yöntemler kullanılmasına karşın ulusal alan yazında öğrencilerin matematiksel güvenlerini ölçebilecek nicel ölçme araçlarının bulunmaması olabilir. Bu nedenle ortaokul öğrencileri için matematiksel güven ölçeğinin geliştirilmesinin amaçlandığı bu çalışmada, geliştirilecek olan matematiksel güven ölçeğinin alan yazına katkı sağlaması ve araştırmalar için öncü olması beklenmektedir. Araştırmada nicel araştırma desenlerinden tarama modeli kullanılmıştır. Çalışmada iki aşamalı örneklem seçimi yapılmıştır. İlkinde 359 ortaokul öğrencisi katılmış ve bu öğrencilerden elde edilen verilerle ölçeğin yapısını belirlemek üzere açımlayıcı faktör analizi yapılmıştır. İkincisinde 145 ortaokul öğrencisi katılmış ve elde edilen verilere doğrulayıcı faktör analizi uygulanarak ölçeğin yapısının doğrulaması yapılmıştır. Çalışmanın sonucunda ortaokul öğrencilerinin matematiksel güven düzeylerini belirleyebilecek 10 maddeden oluşan geçerli ve güvenilir bir ölçme aracı geliştirilmiştir.

İncele - MakaleAçık Erişim2021The relationship between attitudes toward the teaching profession, occupational resilience belief, and extra-role behavior: A moderated mediation model
Kara, Kürşad; Ada, Kübra
This study aims to examine the direct and indirect relationships between pre-service teachers’ attitudes toward the teaching profession, their occupational resilience beliefs, and their tendency to engage in extra-role behaviors within the framework of structural equation modeling. A relational survey model was used to design this quantitative investigation. The sample comprises 430 pre-service teachers who enrolled at four different programs at a state university in Turkey. The study used the attitudes toward teaching profession scale, the occupational resilience beliefs scale for pre-service teachers, and the extra-role behaviors scale (teacher form) as data collection tools. The researchers created hypothesis models examining the mediating and moderated mediating role of the occupational resilience belief in the effect that attitudes toward the teaching profession have on extra-role behaviors and tested these models within the framework of structural equation modeling. As a result of the study, it was found that the relationship strength between the attitudes toward the teaching profession, the occupational resilience belief, and extra-role behaviors was moderate. The study determined that occupational resilience belief plays a mediating role in the effect of pre-service teachers’ attitudes toward the teaching profession on extra-role behaviors. According to the results of the moderated mediation analysis, the influence of this indirect effect on extra-role behaviors varies according to the type of program studied, even though it does not differ significantly according to the class level of the pre-service teachers. This indirect effect is provided at the best level for pre-service teachers in the mathematics education program. However, the study concluded that the indirect effect influence significantly weakened in the Turkish education program.

İncele - MakaleAçık Erişim2020Scopus SJRQ3Examination 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.
