ABSTRACT


FINDING ANCHORING ANALOGIES TO HELP STUDENTS’ MISCONCEPTIONS IN PHYSICS

The first purpose was to develop a diagnostic test to investigate new anchoring and bridging analogies. Second one was to compare the effects of bridging analogies based instruction (BABI) versus traditional teaching method (TTM) on sophomore students’ misconceptions in Newton’s Third Law (NTL).

An Anchoring Analogy Diagnostic Test (AADT), Newton’s Third Law Misconception Test (NTLMT), and Attitude Scale toward Newton’s Third Law (ASNTL) were used as measuring tools.

Unlike single analogies in each step as used in literature, the researcher introduced the group concept and developed the new style of concept diagrams after the first part. The second part was conducted with 308 students in the same department of the same public universities of previous year sample in 2006-2007. In the study, the instructors administered the NTLMT and ASNTL as a pretest. One instructor had randomly assigned one control and one experimental group, while the other instructor (researcher) had randomly assigned two groups. Experimental groups were instructed by the BABI while control groups were instructed by the TTM. After three-week treatment period, the same tests were given as posttests to both groups.

The first part analyzed by using both Excel and SPSS indicated that the AADT was effective in diagnosing anchoring analogies, bridging analogies, and target cases. It was also easy to develop the new style of concept diagrams. The second part were analyzed by using multivariate analysis of covariance (MANCOVA). According to the results, the BABI significantly remediate students’ misconceptions in the NTL with respect to the TTM. However, the BABI showed no significant effect on students’ attitudes toward the NTL with respect to the TTM.


Keywords: Physics Education, Newton’s Third Law, Bridging Analogies Teaching Strategy, Misconception, Attitude.

Çalışmanın ilk temel amacı Newton’un Üçüncü Kanunu (NÜK) konusunda kullanılabilecek yeni temel ve birleştirici benzetmelerin araştırılabileceği bir tanı testi geliştirmek, ikincisi ise birleştirici benzetme yöntemine dayalı öğretimin (BBYDÖ), ikinci sınıf üniversite öğrencilerinin NÜK konusundaki kavram yanılgılarına olan etkisini geleneksel öğretim metodu (GÖM) ile karşılaştırmaktı.

Çalışmada ölçme araçları olarak Temel Benzetme Tanı Testi (TBTT), NÜK Kavram Yanılgısı Testi (NÜKKT), NÜK’e Karşı Tutum Ölçeği (NÜKTÖ) kullanılmıştır.

Alınyazında kullanıldığı gibi her basamağında tek bir benzetmeden oluşan kavram şemalarının aksine birinci kısmın sonunda araştırmacı yeni tip kavram şemaları geliştirmiş ve grup kavramını ortaya atmıştır. Çalışmanın ikinci kısmı, önceki senenin örneklemindeki aynı devlet üniversitelerinin aynı bölümlerinde okuyan 308 üniversite öğrencisinin katılımıyla 2006-2007 yılında gerçekleştirilmiştir. Öğretim elemanları çalışmada, NÜKKT ve NÜKTÖ’yü tüm sınıflarına ön test olarak uygulamışlardır. Bir öğretim elemanının rasgele atanmış bir kontrol bir deneysel grubu aynı zamanda araştırmacı olan diğer öğretim elemanının ise ikişer grubu olmuştur. Deneysel gruplarda BBYDÖ’le ders işlenirken kontrol gruplarında GÖM’le ders anlatılmıştır. Aynı testler üç haftalık bir eğitimden sonra son test olarak iki gruba da tekrar uygulanmıştır.

Çalışmanın Excel ve SPSS kullanılarak analiz edilen ilk kısmının sonuçları, TBTT’nin temel benzetmeleri, birleştirici benzetmeleri ve hedef olayları teşhis etmede etkili olduğunu göstermiştir. Ayrıca yeni stil kavram şemalarının kolayca geliştirilebildiği de görülmüştür. İkinci kısım, SPSS ile çok yönlü varyans analizi (MANCOVA) kullanılarak analiz edilmiştir. Çalışmanın sonuçlarına göre BBYDÖ, öğrencilerin NÜK konusunda sahip oldukları kavram yanılgılarını GÖM’e göre anlamlı derecede gidermiştir. Fakat, NÜK’e karşı tutumlarına göre BBYDÖ ve GÖM arasında anlamlı bir fark oluşmamıştır.


Anahtar Kelimeler: Fizik Eğitimi, Newton’un 3. Kanunu, Birleştirici Benzetme Öğretim Yöntemi, Kavram Yanılgısı, Tutum.

ACKNOWLEDGEMENTS


I would like to express my gratitude to Assist. Prof. Dr. Ali Eryılmaz. I owe a special word of gratitude to him for his sound advice, patient guidance and sincere courage. He has been always there whenever I need him. Without his invaluable support it was impossible for me to complete my thesis.

I would like to extend my gratitude to other examining committee members Prof. Dr. Giray Berberoğlu and Prof. Dr. Fitnat Kaptan for their helpful critique, feedback and comments.

I wish to express my deep appreciation to my friend research assistant Almer Güngör Abak who participated in this study and spent her valuable weeks by conducting this study in her university for the sake of my study. And also thankful to the students who participated in this study.

Throughout the Ph.D. period there was one power that provided me with the moral support and encouragement to successfully fulfill this thesis. Thanks and claps are to you-my dear family, my fiancé Mualla, my sister Sema, my brother Savaş, my sweet niece Edanur and nephews Emre and little Burak Berk. And special thanks to my colleague, roommate and close friend Pınar Özdemir, and to my friends; Sezai, Özgür, Murat, Menekşe, Eda, İlke and Mr. Sinan Erten. Thank you all very much indeed.
