Abstract

Araştırma öğrencilerin bilgisayar programlama dersinde başarısız olması problemine yönelik olarak programlama başarısını etkileyen bazı faktörlerin belirlenmesi ve incelenmesi amacıyla yapılmıştır. Araştırma 2016-2017 eğitim öğretim yılında Ondokuz Mayıs Üniversitesi Bilgisayar ve Öğretim Teknolojileri Eğitimi ikinci sınıf öğrencileri ile yürütülmüştür. Çalışmaya Programlama Dilleri I dersini alan 67 öğrenci katılmıştır. Araştırmada programlama yeteneği, mantıksal düşünme yeteneği, öğrenme stili, öz yeterlilik, bilgisayar deneyimi ve programlama deneyimi değişkenleri ile programlama başarısı arasındaki ilişkiler incelenmiştir. Araştırmada Bilgisayar Programlama Yetenek Testi, Mantıksal Düşünme Yeteneği Testi, Kolb Öğrenme Stilleri Envanteri (III), Programlamaya İlişkin Öz yeterlilik Ölçeği ve Programlama Başarı testleri kullanılarak veri toplanmıştır. Programlama yeteneği, mantıksal düşünme yeteneği, programlama öz yeterliliği, bilgisayar deneyimi ve programlama deneyimi ile programlama başarısı arasındaki ilişkiyi belirlemek için korelasyon analizi yapılmıştır. Öğrencilerin sahip oldukları öğrenme stiline göre programlama başarıları arasında bir fark olup olmadığını anlamak için ilişkisiz örneklemler için tek yönlü varyans analizi yapılmıştır. Programlama yeteneği, mantıksal düşünme yeteneği, öğrenme stili ve programlama öz yeterliliği birlikte programlama başarısını hangi önem sırasında ve ne düzeyde açıklayabildiğini belirlemek için çoklu regresyon analizi yapılmıştır. Araştırma sonucunda programlama yeteneği, mantıksal düşünme yeteneği ve bilgisayar deneyimi ile programlama başarısı arasında istatistiksel olarak anlamlı bir ilişki bulunamamıştır. Programlama öz yeterliliği ile programlama başarısı arasında orta seviyede bir ilişki bulunmuştur. Öğrencilerin programlama ile uğraştıkları yıl baz alınarak hesaplanan programlama deneyim ile programlama başarısı arasında düşük seviyede bir ilişki bulunmuştur. Çalışmaya katılan öğrenciler arasında en çok tercih edilen öğrenme stili Özümseme, ikinci sıradaki stil ise Ayrıştırma stilidir. En başarılı stil Ayrıştırma stili olurken, en başarısız stil Özümseme olarak belirlenmiştir. Yapılan ANOVA testi sonucunda öğrenme stilleri ortalamaları arasında anlamlı bir fark olduğu bulunmuştur. Yapılan regresyon analizine göre programlama başarısının %41'i ele alınan bağısız değişkenler tarafından açıklanabilmektedir. This research is conducted to define and investigate the factors that impact the programming success which comes from the problem of students being unsuccessful in programming lessons. The research is undertaken by Computer Education and Instructional Technology department, second year students in 2016-2017 academic year at Ondokuz Mayıs University. 67 students from the class of Programming Languages 1 contributed to the study. In this research, relationship between programming ability, logical thinking ability, learning style, computer programming self-efficacy, computer experience, programming experience and programming success are studied. Data was collected by using computer programming ability test, logical thinking ability test, Kolb learning styles inventory (III), computer programming self-efficacy and programming success tests. Correlation analysis has been applied to define the relation between programming ability, logical thinking ability, programming self-efficacy, computer experience, programming experience and programming success. In order to understand how programming success varies according to learning styles, one way variance analysis is conducted for unrelated random samples. Multiple regression analysis was applied to describe the programming success in which level and importance with programming ability, logical thinking ability, learning style, programming self-efficacy. According to the results of the study, a significant relation between programming ability, logical thinking ability, computer experience and programming success was not found. However, there was a mid-level relation between programming self-efficacy and programming success. There was a low level of relationship between programming experience and programming success, calculated on the basis of the years students were involved with programming. The most preferred learning style was Assimilating followed by Converging, whereas the most successful one was Converging and the less successful was Assimilating. A significantly difference between training styles' averages was found by ANOVA test. According to regression analysis 41% of the programming success can be explained by independent variances. 108

Abstract

Bu araştırma, Yükseköğretim Programı'nda bulunan İngilizce dersinin öğretiminde seviye sistemine göre, Anlamsal web uygulamasının öğrenci erişisine ve içsel denetim odağına etkisini belirlemek amacıyla yapılmıştır. Araştırma, 2015-2016 öğretim yılı ikinci döneminde Ondokuzmayıs Üniversitesi Vezirköprü Meslek Yüksekokulu'nda yürütülmüştür. Araştırmada ön test/ son-test kontrol gruplu yarı deneysel desen kullanılmıştır. Bilgisayar Programcılığı bölümü birinci öğretim birinci sınıfı kontrol grubu, Bilgisayar Programcılığı bölümü ikinci öğretim birinci sınıfı ise deney grubu olarak belirlenmiştir. Hazırlanan eğitim materyali ve sistem Ondokuzmayıs Üniversitesi Ön lisans İngilizce Ydi 102 dersi müfredatına göre düzenlenmiş olunup, İngilizce alan hocalarının onayına sunulmuştur. Daha önce başka bir çalışmada İngilizceden Türkçeye çevrilerek geçerliği ve güvenilirliği ispat edilen İçsel Denetim Odağı ölçeği her iki gruba da dönem başında uygulanmıştır. Müfredata uygun olarak 2 adet seviye belirleme sınavı anlamsal web sistemine göre internet tabanında hazırlanmıştır. Biri dönem başında olmak üzere, diğerleri her konu bitiminde uygulanmıştır. Kullanıcının seviyesine ve konuya uygun içerikleri içeren internet siteleri önceden veri havuzuna kaydedilmiştir. Kullanıcının seviyesine göre sisteme girdiğinde bu siteler, kişinin erişimine kolayca sağlanmıştır. Kontrol grubu ise bu sisteme dahil edilmeden sadece İngilizce eğitimlerine olağan şekilde devam etmişlerdir. Bu çalışma, İngilizce eğitiminde seviye sistemine göre etkinlik geliştirme ve kaynak sunma sürecinde kullanıcılara aradıkları kaynakları web tabanında paylaşmayı ve tekrar erişimlerin sağlayacak bir araç geliştirmeyi ve etkililiği amaçlamıştır. Üretilen öğrenme nesnelerinin paylaşımı ve tekrar kullanımı sayesinde gerek bu sistemde gerekse internet tabanında kullanıcı aradığı konuyla ilgili olarak en doğru sonuca en kısa sürede ulaşmıştır. Kullanıcı kendi seviyesine göre aradığı konulara en doğru ve en hızlı şekilde ulaşmıştır. The aim of this research is to determine the impact of internal locus of control, on student access , according to the level system which is made of Semantic Web applications in the teaching of the higher education programme. The research, was conducted in the second term of 2015-2016 academic year, fn Ondokuzmayıs University Vezirköprü Vocational School. In this research, the pretest / posttest experimental design within non-equivalent control group was used. Computer programming department first class daytime education were randomly assigned to the control group. Computer programming department first class evening education has been identified as the experimental group. Prepared training material was organised according to the Ondokuzmayıs University English course ydi 102 lecture curriculum. Both the material and pretest posttest were submitted to the approval of the English field teachers. The locus of control scale which had validity and reliability was previously translated from English to Turkish and was administered to both groups at the beginning of the research. Two level tests which are suitable for the curriculum has been prepared in accordance with the semantic web base system. One of them is going to be applied at the beginning of the term and the other is at the end of the every subject. The web sites, including the level of user had been recorded to the database system on the semantic web material. When the user enter the system, the web sites shown to them according to the user's level. The control group did not enter this semantic web system. They study only by the classical method. This study aims to develop a material in English education level system so that the users can access the web pages and on line resources effectively and easily to improve their learning by themselves. By the sharing and reuse of this produced material the users can reach the right resources easily and immediately. So that they can improve their levels. 79
