The purpose of this research is to investigate characteristics of science content knowledge and pedagogical content knowledge shown in the primary school science classes. Through analysis of classroom teaching, explore the features and differences between primary and secondary school science PCK. Using open-ended interviews with the teachers and group discussions on a regular basis to analyze and compare classes of five primary school teachers, the relationship between CK and PCK. Regardless of the school level the teacher's PCK and professionalism is required with varying focus and emphasis. The features of the primary school teacher's PCK are as follows: Firstly, elementary teach secondary teach content, teachers value pedagogical knowledge (PK) content knowledge (CK). The primary school PCK requires more of understanding of students and teaching methods that to subject areas. PCK be without content knowledge, and the teacher's PCK is subject-specific In addition to the characteristics of PCK in the primary school science teaching, ways to set up professional exchange or collaboration between primary and secondary teachers, and to provide supplementary in-service training focused on content knowledge for primary school teachers.

이 연구에서는 인식적 네트워크 분석(ENA)을 통해 초등 예비교사의 VR/AR 콘텐츠 활용 과학 수업 계획 과정에서 나타나는 TPACK의 특징을 알아보고자 했다. 연구자들은 기존의 TPACK 프레임워크에 기초하여 7개의 TPACK 코딩 요소를 귀납적으로 추출하였다. 그리고 초등 예비교사들이 과학 수업을 계획하며 나누는 담화를 TPACK 요소에 따라 코딩하고 이를 ENA Web Tool로 분석하였다. 두 모둠의 담화를 분석하고 비교하였는데 연구자들이 질적으로 분석한 두 모둠의 담화의 차이는 ENA 그래프를 통해 명확하게 드러났다. 이러한 연구 결과를 바탕으로 연구자들은 ENA 방법이 기존 TPACK 연구와 달리 테크놀로지 지식(TK), 내용 지식(CK), 교수 지식(PK)의 복합적 상호작용을 분석할 수 있는 유용한 연구 방법임을 주장하였다. 그리고 두 모둠의 담화에서 나타나는 특징을 통해 예비교사의 TPACK 역량 함양을 위한 시사점을 논의하였다.

Teacher quality is a topic of international concern, as it impacts student learning and teacher preparation. This study compared the undergraduate secondary science teacher preparation programs from two universities in Korea with those of Oregon, USA. We examined the programs' structural curricular coherence, conceptual curricular coherence, and curricular balance. Structural curricular coherence was determined by examining the overarching goals of the institutions' programs, the organization of the programs of study in terms of meeting those goals, and outside bodies of evidence. All universities were in structural coherence for various reasons. Conceptual curricular coherence was determined by examining students' perceptions of the connection between their preparation and their clinical practice. In case of Korea, most students from both universities were not satisfied with their practical preparation. In the US, the students from both institutions felt well prepared to transition to inservice teaching. To determine curricular balance, we examined the institutions' preparation programs looking at the credit hours taken in the four main areas of the teacher knowledge base: GPK (General Pedagogical Knowledge), SMK (Subject Matter Knowledge), PCK (Pedagogical Content Knowledge), and CK (Contextual Knowledge). The total credit hours taken in each category was very similar by country but the application and field component in the USA was far greater than those of Korea where the focus was heavily on SMK and PCK. The main reason for these may be the nations' licensing and employment processes.
