10. Sınıf Öğrencilerinin Kimyasal Bağ ile ilgili Algıları, Kimyasal Bağı Tanımlamada Kullandıkları Metaforları ve Yaptıkları Benzeşimler

Bu çalışmada kimyasal bağlar konusunu öğrenmelerinden sonra, ortaöğretim öğrencilerinin kimyasal bağ kavramını nasıl algıladıkları, kimyasal bağı tanımlamada kullandıkları metaforları ile kimyasal bağı ne ile özdeşleştirdikleri araştırılmıştır. Bu amaçla geliştirilen iki aşamalı bir ölçme aracı kullanılarak, 184’ü kadın ve 113’ü erkek olmak üzere 5 farklı liseye devam eden toplam 297 onuncu sınıf öğrencisinden veri toplanmıştır. İlk aşamada öğrencilerin algı ve metaforlarını belirlemek için kimyasal bağı tanımları istenmiştir. İkinci aşamada öğrencilerin kimyasal bağ ile ilgili benzeşimlerini belirlemek amacıyla üzerinde “kimyasal bağı ……. benzer, çünkü…..” yazılı bir soru öğrencilere verilmiştir. Çalışma sonunda öğrencilerin kimyasal bağ algılarının 5 başlık altında ve metaforlarının da 6 kavramsal kategoride toplandığı belirlenmiştir. Öğrenciler tarafından yazılan benzeşimlerin analizi sonucunda, bunların da 7 tema altında toplandığı sonucuna ulaşılmıştır.  

10th Grade Students' Perceptions about Chemical Bond, their Metaphors Used in Definition of Chemical Bond and their Analogies

In this study, after teaching the subject of chemical bonding how secondary school students perceive the concept of the chemical bond, which metaphors they use to define the chemical bond and what they associate with the chemical bonding were investigated. Data were collected from 297 tenth grade students attending 5 different high schools, 184 female and 113 male, using a two-stage measurement tool developed for this purpose. In order to determine the students' perceptions and metaphors, in the first stage of the scale, students were asked to define chemical bonding. In the second stage, A question containing the statement “chemical bond is like……. because ……” was given to the students to obtain their analogies about chemical bond. At the end of the study, it was determined that the chemical bond perceptions of the students were collected under 5 themes and their metaphors were collected in 6 conceptual categories. As a result of the analysis of the analogies provided by the students, it was concluded that these were collected under 7 themes.
