Öğe Evaluation of the articles in a scientific journal using quantitative data analysis program(Bayburt Eğitim Fakültesi, 2017) Kutluca, Tamer; Mut, Ali İhsan; Gündüz, SametAbstract The purpose of this study is to reveal tendencies of articles within which quantitative data analysis program was used, and that were published in a scientific journal in Turkey by examining them thoroughly. For this research, out of 525 articles published in the Hacettepe University Journal of Education between the years 2011 and 2015, 184 articles, for the analysis of which SPSS, LISREL and AMOS softwareprograms were utilized, were probed by means of content analysis method. The data obtained from the study were presented as the form of tables including frequency, standard deviation, mean and percentage ratios, and then this data were interpreted accordingly. The articles were analyzed according to publication year, number of authors, language, sample size and group of sample, data analysis tool, research design, and the number and the method of data analysis. As a result of the study, it was determined that the vast majority of the articles were published in 2012 and 2013. Moreover, more than half of the articles were written in Turkish and conducted by two authors. It has been determined that the majority of sample groups were composed of university students and the researchers studied with sample groups with 101-300 participants at most. In addition, two different data analysis methods were used in most of the articles. It was determined that t-test, descriptive statistics and ANOVA were mostly used as data analysis methods. In these studies, quantitative research methods were utilized mainly as the research design, and SPSS was the most utilized software as the data analysis program.Öğe Evaluation of the published articles in Turkish journal of computer and mathematics education according to content analysis(Karadeniz Technical University, 2018) Kutluca, Tamer; Birgin, Osman; Gündüz, SametAs an international refereed journal related to computer and mathematics education researches, Turkish Journal of Computer and Mathematics Education (TURCOMAT) has been released since 2009 and publishes articles in Turkish and English. This study aimed to reveal the tendencies by examining the articles published in TURCOMAT journal. In the study, a total of 151 articles in the TURCOMAT published between 2009-2017 years were analyzed by content analysis method. Articles in the journal were examined according to publication year, number of authors, languages, fields, authors' titles, sample groups, sample sizes, research methods, research designs and source numbers. Findings were presented descriptively using frequency and percentage value. As a result of the study, it was determined that the nearest halves of the articles were written by two authors and the most among the authors were assistant professors. The vast majority of the articles were in Turkish and more than half of the articles were prepared in the field of mathematics education. It was found that participants in the reviewed studies as sample groups were mostly undergraduate students and majority of the studies employed samples sizes between 31-100 participants. The qualitative research method and case study design were used more frequently in the researches. Moreover, it was determined that the foreign sources used in the articles more than the domestic sources.Öğe Gerçekçi matematik eğitimi yaklaşımının akademik başarıya ve tutuma etkisi üzerine bir meta-analiz çalışması(Hacettepe Üniversitesi Eğitim Fakültesi, 2022) Kutluca, Tamer; Gündüz, SametBu araştırmada gerçekçi matematik eğitimi yaklaşımının, öğrencilerin akademik başarısına ve matematiğe yönelik tutumlarına etkisini incelemek amaçlanmıştır. Araştırmada akademik başarıya yönelik 67 çalışma ve tutuma yönelik 27 çalışma incelenmiştir. Yapılan inceleme sonucunda bu çalışmalardan dâhil edilme kriterlerine uygun olan akademik başarı için 37 ve tutum için 15 çalışmaya ait veriler meta-analiz yöntemiyle birleştirilmiştir. Çalışmalar birleştirilirken yapının heterojen olmasından dolayı rastgele etkiler modeli kullanılmıştır. Araştırma sonucunda genel etki büyüklüğü değeri akademik başarı için 1.107 ve matematiğe yönelik tutum için 0.694 olarak bulunmuştur. Sonuç olarak gerçekçi matematik eğitimi yaklaşımının akademik başarıyı arttırmada çok geniş düzeyde ve matematiğe yönelik tutumu arttırmada ise orta düzeyde bir etkiye sahip olduğu belirlenmiştir.Öğe Matematik ve fen bilimleri öğretiminde akıllı tahta kullanımının öğrencilerin akademik başarılarına etkisi üzerine bir meta-analiz çalışması(Dicle Üniversitesi, Eğitim Bilimleri Enstitüsü, 2018) Gündüz, Samet; Kutluca, TamerBu araştırmada matematik ve fen bilimleri öğretiminde akıllı tahta kullanımının öğrencilerin akademik başarıları üzerindeki etkisini incelemek amacıyla meta-analiz çalışması yapılmıştır. Araştırmada 2008-2018 yılları arasında gerçekleştirilmiş 35 çalışma incelenmiş ve dâhil edilme kriterlerine uygun olan 25 çalışma meta-analiz yöntemiyle birleştirilmiştir. 25 adet çalışmanın örneklemini kontrol grubunda 878, deney grubunda 893 olmak üzere toplam 1771 öğrenci oluşturmaktadır. Meta analitik analizler yapılırken Comprehensive Meta-Analysis 2.2 istatistik programından yararlanılmıştır. Çalışmalar birleştirilirken yapının heterojen olmasından dolayı rastgele etkiler modeli kullanılmıştır. Araştırma sonucunda, matematik ve fen bilimleri öğretiminde akıllı tahta kullanımının öğrencilerin akademik başarısına etki büyüklüğü 0.807 olarak bulunmuştur. Bu değer yapılan sınıflandırmaya göre geniş düzeyde bir etki büyüklüğüdür. Buna göre akıllı tahta kullanımının öğrencilerin akademik başarısını arttırmada olumlu yönde ve geniş düzeyde bir etkiye sahip olduğu sonucuna ulaşılmıştır. Akademik başarıya olan etki büyüklüğü örneklem grubuna göre farklılaşırken, yayım türü, yayım yılı, örneklem büyüklüğü, çalışmanın yapıldığı coğrafi bölge, uygulama süresi ve disiplin alanlarına göre farklılaşmamaktadır. Ulaşılan sonuçlar neticesinde araştırmacılara ve uygulamaya yönelik önerilerde bulunulmuştur.Öğe A Meta-Analysis Study on the Effect of the Use of Smart Board in the Teaching of Mathematics and Science to Students’ Academic Achievements(2019) Kutluca, Tamer; Gündüz, SametIn this study, a meta-analysis study was conducted to investigate theeffect of the use of smart board on students’ academic achievements inthe teaching of mathematics and science. In this meta-analysis research,35 studies carried out between 2008-2018 were analyzed and 25 studiessuitable for inclusion criteria were combined with the meta-analysismethod. Because of the heterogeneous structure, random effects modelwas used while combining the studies. At the end of the currentresearch, the effect size of the smart board usage on students’achievement in mathematics and science was found as 0.807. Theresearch leads to conclusion that usage of smart boards has a large andpositive impact on improving students’ academic achievement. Whilethe effect size to the academic achievement varies according to thesample group, it does not vary with respect to publication type,publication year, sample size and disciplinary areas.Öğe Metaphoric Perceptions of Secondary School Students about Smartboard Concept(Politik Ekonomik ve Sosyal Araştırmalar Merkezi, 2020) Gündüz, Samet; Kutluca, Tamer; Kutluca, SevtapThis study was carried out to reveal the metaphorical perceptions of secondary school students about the concept of smart board. In this research phenomenology which is one of a qualitative research, is used. The study group of the research consists of a total of 226 secondary school students, 93 of whom are girls and 133 are boys, at a public school where the smart board installation is completed. For the collection of the data, students were asked to complete the sentence “Smartboard is like ……; because ……”. Content analysis technique was used in the analysis of the data. The data obtained from the study were presented as the form of tables including frequency and percentage ratios, and then this data were interpreted accordingly. In some places, students' views are included with direct quotations. As a result of the research, have been identified that students produced 23 different metaphors. These metaphors are grouped as six different categories in terms of their features. The most television, computer and telephone metaphors about the concept of smart board have been produced.
