The current study aimed to investigate pre-service primary teachers espoused pedagogical content knowledge for teaching nature of science. Mainly, the research was focused on how pre-service primary teachers’ interpretations of nature of science were attributed to their espoused pedagogical content knowledge for teaching nature of science. Participants of the study were 12 (10F, 2M) pre-service primary teachers who were supposed to teach to K-4 level. Data was collected by means of qualitative data collection tools. Content representations (cores), lesson plans and feedback forms were the data sources of the study. The data was collected in the context of science teaching method course in which the intervention phase of the study have been taken and lasted four weeks. First, participants were introduced to “core” development task within the intervention phase. Through this task, participants formed groups of four and discussed and revised their cores within groups. During group discussions, participants were required to address issues like the importance of the content, the difficulties that students might face through learning of the content, the teaching methods they planned to use, nature of science integration to the content, and evaluation and assesment strategies. In addition to core development, each participant required to fill a feedback form in which they evaluated one of the peer’s cores for each week based on the pre-determined criteria. Regarding data analysis, each data source analysis included category construction, and search for patterns regarding participants’ espoused pedagogical content knowledge for nature of science teaching. Findings of the study revealed that, few of the participants could be able to address nature of science in an explicit reflective way in their cores. However, majority of the participants demonstrated emergence of pedagogical content knowledge for theaching nature of science. That is, they indicated necessity of nature of science inclusion in an explicit reflective way in their responses to feedback forms. This result implied that, pre-service teachers could be taught on internationization of nature of science as a valuable learning outcome which is an important component of development of pedagogical content knowledge for teaching nature of science.
Özet
Bu araştırma sınıf öğretmeni öğretmen adaylarının bilimin doğasını öğretimini belirlemeye yönelik gerçekleştirilmiş nitel bir çalışmadır. Çalışma, 12 üçüncü sınıf, sınıf öğretmeni adayı ile Fen ve Teknoloji öğretimi dersi kapsamında gerçekleştirilmiştir. Sınıf öğretmeni adaylarının bilimin doğası öğretimlerini incelemek amacı ile adaylardan içerik gösterimi hazırlamaları ve grup arkadaşlarının hazırladıkları üç adet içerik gösterimini bir yönerge ışığında grup çalışması ve tartışması yaparak değerlendirmeleri istenmiştir. Katılımcılar yaptıkları tartışma ve değerlendirme sonrası içerik gösterimlerini gözden geçirmiş ve son halini vermiştir. Yapılan nitel içerik analizi sonucunda öğretmen adaylarının bilimin doğası öğretimleri belirlenmeye çalışılmıştır. Analiz sonuçları, çok az sınıf öğretmeni öğretmen adayının bilimin doğasını açık yansıtıcı bir biçimde içerik gösterimlerinde yer verdiğini göstermiştir. Öğretmen adaylarının hazırlamış oldukları içerik gösterimlerinde bilimin doğası konusuna çoğunlukla dolaylı olarak değinilmiş, yapılan etkinlik ve deneyler sonucunda bilimin doğası ile ilgili gerekli çıkarımların yapılacağı varsayılmıştır. Buna karşın, adayların değerlendirmesini yapmış oldukları içerik gösterimleri çoğunlukla bilimin doğası açık yansıtıcı bir yaklaşımla vurgulanmadığı için eleştirilmiştir. Yani, katılımcıların büyük çoğunluğunun bilimin doğasının açık ve doğrudan bir şekilde entegre edilmesi gerekliliği düşüncesinin oluşturulmasında, katılımcıalra katkı sağlanmıştır. Bu bulgu, bilimin doğasını öğretmeye yönelik pedogojik alan bilgisinin önemli bileşenlerinden biri olan bilimin doğasının önemli bir öğrenim kazanımı olarak algılanmasının, öğretmen adaylarına benimsetilebileceğini ve bu algının geliştirebileceğini göstermişti.
