Ortaokul Öğrencileri İçin Geometriye Yönelik İnanç Ölçeği Geliştirme Çalışması

Abstract

The aim of this study was to develop a valid and reliable instrument for determining the geometry of the beliefs of the middle school students. Belief items were formed benefiting from the relevant literature and in order to determine content validity, experts were consulted. Draft scale with 32 items applied to the 324 middle school students. To ensure the construct validity of the scale exploratory and confirmatory factor analysis were done. For further total-item correlations and item distinctiveness were calculated. After factor analysis it was determined that five-point Likert-type scale consists of 3 factor and 16 items. The results of the reliability analysis Cronbach's alpha was found 0,755.

Matematik Başarısının Geometriye Yönelik Tutum ve Geometri İnancı ile İlişkisinin İncelenmesi

“…The population of the study is middle school students who are studying at a secondary school in Turkey's Mediterranean region. In the study, "Personal Information Form" developed by researchers, "Belief in Geometry Scale" developed by Ünlü and Ertekin (2018) and "Geometry Attitude Scale" developed by Bulut, Ekici, İşeri and Helvacı (2002) have been applied to the secondary school students as data collection tools.…”

Evaluation of Geohepta Mobile Application-Based Instructions' Impacts on Affective Behaviors

“…The Geometry Self-Efficacy Scale (Cantürk-Günhan & Başer, 2007), the Geometry Belief Scale (Ünlü & Ertekin, 2018), and the Scale of Pupils' Attitude towards Technology (Yurdugül & Aşkar, 2008) were all employed in the research on mathematics education based on the GeoHepta mobile application. The experimental and control groups underwent pre -and post-tests using the Geometry Self-Efficacy Scale (Cantürk-Günhan, 2007), Geometry Belief Scale (Ünlü & Ertekin, 2018), and Scale of Pupils' Attitude towards Technology (Yurdugül & Aşkar, 2008). substantial deviation between pre -and post-test scores.…”

“…The Geometry Belief Scale, created by Ünlü and Ertekin (2018) and whose validity and reliability were confirmed on secondary school students, was used to ascertain students' beliefs about geometry. The 3-factor Beliefs Towards Geometry Scale has 16 items on a five-point Likert scale.…”

“…The results of the study showed that there is a significant relationship between belief in geometry and success in geometry (Erdoğan, Baloğlu, & Kesici;2011). In the literature, it is seen that a scale was developed by Ünlü and Ertekin (2018) in order to examine the beliefs of secondary school students about geometry in studies conducted in the country regarding belief in geometry, and the beliefs of teachers were examined according to branch and gender variables by Paksu (2008). Different studies have been reached abroad to examine the belief in geometry (Ambrose, 2004;Kajander, 2007).…”

Ortaokul Düzeyinde Geometriye Yönelik Bir Tutum Ölçeğinin Geliştirilmesi

“…Öğrenmeyi etkilemesi sebebiyle tutumları etkileyen unsurların belirlenmesinin, değerlendirilmesinin ve gerekli önlemlerin alınmasının eğitimde istenilen amaçlara ulaşılması bakımından önemli olduğu düşünülmektedir (Avcı, Coşkuntuncel, & İnandı, 2011). Geometrinin de, gerek duyuşsal gerekse bilişsel düzeyde incelenmesinin, öğrenimi ve öğretimi açısından önemli olduğu belirtilmiştir (Ünlü & Ertekin, 2018). Bu çerçevede geometriye yönelik tutumların geometride istenilen amaçlara ulaşılması bakımından belirlenmesi önemlidir.…”
