Professional Learning Communities (PLCs) offer a promising context for this professional growth. This study examined the PCK development processes of three primary school teachers with varying experience levels as they participated in five MBI-focused PLC sessions. PCK changes were traced using an integrated analytical framework that combined the Interconnected Model of Teacher Professional Growth (IMTPG) with the Refined Consensus Model (RCM). Findings revealed positive growth across PCK components, though pathways varied. While curriculum knowledge development was often characterized by refinement based on prior knowledge (change sequences), growth in knowledge of student understanding, instructional strategies, and assessment typically demonstrated more complex, interconnected growth networks involving dynamic knowledge exchange, shaped by interactions among personal, collective, and enacted PCK, as well as individual orientations. The study highlights the potential of PLCs as spaces for practice-based learning, supporting sustained PCK development, and demonstrates the utility of the combined IMTPG–RCM framework for analyzing the nuances of teacher growth over time.</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">1148-1168</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Seong-un Kim</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE TYPES OF PEER SCAFFOLDING IN SCIENTIFIC EXPERIMENTAL ACTIVITIES</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Baltic Science Education</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">peer scaffolding</style></keyword><keyword><style  face="normal" font="default" size="100%">qualitative case study</style></keyword><keyword><style  face="normal" font="default" size="100%">scientific experimental activities</style></keyword><keyword><style  face="normal" font="default" size="100%">students’ interaction</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2022</style></year><pub-dates><date><style  face="normal" font="default" size="100%">August/2022</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://oaji.net/articles/2022/987-1662186805.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">21</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This study studied the types of peer scaffolding presented in scientific experimental activities. The study included 14 university students. For the experimental activity of ‘determining temperature changes using the meridian altitude of the sun,' information regarding experimental behaviors, thinking aloud, discourse, and retrospective interview data were collected and analyzed. A model was derived and utilized for experimental activities to analyze peer scaffolding, wherein students internally structured their experiences with the experimental activities. The results indicated that students utilized seven means of peer scaffolding: ‘demonstrating’, ‘assisting’, ‘monitoring’, ‘posing’, ‘questioning’, ‘explaining’, and ‘suggesting’. Three types of peer scaffolding emerged: task completion-, model elaboration-, and learning support-oriented scaffolding. Each type differed in purpose, main mean, and major explanation details. Additionally, this study has observed the level of the model for the experimental activities and the time that had been provided to understand the experimental procedure influenced the three peer scaffolding types. These outcomes indicate that providing ample time to students independently structure the experimental procedure and supporting other students during experimental activities are essential. Moreover, providing assistance to students in focusing on observable phenomena by reducing the cognitive load required to process the experimental procedure is crucial.</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">594-614</style></section></record></records></xml>
