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. ÖzetBu 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.

Pedagogical content knowledge for teaching the nature of science (PCK for NOS) has attracted interest in recent decades. This study investigated the PCK for NOS of six novice chemistry teachers with various educational backgrounds. An interpretive case study was performed. Multiple data sources including classroom observations, field notes, semi-structured interviews, and teachers' artifacts were collected. The inductive process used to analyze data involved categorical aggregation, followed by a search for patterns and themes. The findings revealed that all participants had limited PCK for NOS in terms of all of its components. They had robust chemistry knowledge and expressed adequate views of a few aspects of NOS. The teachers focused only on the chemistry content and rarely taught or reflected NOS in their real practices. The findings indicate that the teachers did not reflect or teach NOS, which might have resulted from inadequacies in their teacher preparation courses, which did not greatly emphasize teaching NOS. The results of this research indicate that science educators and professional developers should use PCK for NOS not only as a lens to shed light on teachers' teaching of NOS but also as a framework to revisit the teaching of NOS in science teacher preparation courses.


Technological pedagogical content knowledge (TPACK) is a dynamic theoretical description of teachers' knowledge for designing, implementing, and evaluating curriculum and instruction with digital technologies. TPACK portrays the complex interaction among content knowledge, pedagogical knowledge, and technological knowledge for guiding all teachers (K-12 and higher education faculty) in the strategic thinking of when, where, and how to direct students' learning with technologies. Teacher educators' and educational researchers' acceptance of the TPACK construct mirrors the acceptance of its parent construct of pedagogical content knowledge (PCK). The importance of teachers' continued practice in integrating technologies is essential for extending and enhancing their TPACK. Connections with the knowledge-of-practice construct suggest calling TPACK TPACK-of-practice to more accurately describe the process of the knowledge development efforts for guiding inservice and preservice teachers in gaining, developing, and transforming their knowledge for teaching as new and more powerful technologies emerge for integration in education. Ultimately, the very nature of the TPACK construct describes a transformation of teachers' knowledge for teaching in the 21st century – a century reframed by robust and advanced technologies that have been integrated into the fabric of a more complex social, cultural, and educational environment.
