ABSTRACT
This study focuses on how teachers’ pedagogical content knowledge (PCK) of mathematics may differ depending on teacher interactions in an online teacher community of practice (CoP). The study utilizes data from 26,857 posts collected from the South Korean self-generated online teacher CoP, ‘Indischool’. This data was then analyzed using natural language processing techniques; specifically, text classification with word2vec, BERT, and machine learning classifiers was used. The results indicate that the texts of posts can predict the level of teacher interactions in the online CoP. BERT embedding and classifier exhibited the best performance, ultimately achieving an F1 score of .756. Moreover, topic modeling utilizing BERT embedding is used to uncover the specific PCK of teachers through high- and low-interaction posts. The results reveal that high-interaction posts with numerous likes and replies demonstrate more in-depth reflections on teaching mathematics and refined PCK. This study makes two significant contributions. First, it applies a data science framework that allows for the analysis of real data from an actual online teacher community. Secondly, it sheds light on the intricacies of knowledge management in an online teacher CoP, an area that has to this point received limited empirical attention.

ABSTRACT
This research was designed and conducted considering the theoretical and practical suggestions of design-based research (DBR) methodology and aimed to identify and address problems in a one-semester technology integration course at a Midwest university in the US. Community of practice (CoP) was used as the theoretical framework in this research to design and implement interventions, and improve the quality of the course. The researcher observed a community of teacher educators and aimed to make suggestions for building successful strategies for communities of practice in similar contexts. The study results showcased the connection between pedagogy, content and technology as an important theme for preparing future teachers in technology integration courses but also in all the teacher education courses. Furthermore, aligned with the previous literature, pre-service teachers’ beliefs and confidence were identified as important conditions for effective technology integration. CoP was found as a challenging but helpful model when all the members share ideas in a supportive and balanced environment. An experienced member of the community acting as a moderator and facilitating the discussions was helpful to address the communication issues in a community of teacher educators.
