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%">Shan Lin</style></author><author><style face="normal" font="default" size="100%">Jian Wang</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">DEVELOPMENT AND APPLICATION OF AN INSTRUMENT FOR ASSESSING UPPER-SECONDARY SCHOOL BIOLOGY TEACHERS’ PEDAGOGICAL CONTENT KNOWLEDGE OF SCIENTIFIC THINKING</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%">assessment instrument</style></keyword><keyword><style  face="normal" font="default" size="100%">pedagogical content knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">scientific thinking</style></keyword><keyword><style  face="normal" font="default" size="100%">upper-secondary school biology teacher</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2024</style></year><pub-dates><date><style  face="normal" font="default" size="100%">June/2024</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://oaji.net/articles/2023/987-1719377648.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">23</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%">Scientific thinking constitutes a vital component of scientific competencies, crucial for citizens to adapt to the evolving societal landscape. To cultivate students’ scientific thinking, teachers should possess an adequate professional knowledge foundation, which encompasses pedagogical content knowledge (PCK). Assessing teachers’ PCK of scientific thinking facilitates the development of effective curricula tailored to their continuous professional development. Despite its significance, empirical studies on biology teachers’ PCK of scientific thinking are notably lacking. Hence, this research aimed to create a reliable and valid tool to evaluate upper-secondary school biology teachers’ PCK of scientific thinking. The results showed that the instrument exhibits high reliability and good validity, affirming its efficiency for investigative purposes. A collective of 292 in-service biology teachers from upper-secondary schools participated in this investigation through the completion of an online survey. The results indicated that, overall, as well as for each component, upper-secondary school biology teachers’ performance on PCK of scientific thinking fell within the lower to middle range. Specifically, the performance levels of four components: knowledge of students (KSU), knowledge of instructional strategies (KIS), knowledge of curriculum (KC), and knowledge of assessment (KA) declined sequentially.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">495-517</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%">Nthoesele Hlaela</style></author><author><style face="normal" font="default" size="100%">Loyiso C.

PCK requires valid measurement at domain-specific level on different components excluding the teaching context. While the research focuses on measuring the PCK of unqualified teachers and pre-service teachers, the description of qualified teachers’ domain-specific PCK is often overlooked. The purpose of this study was to measure quantitatively the domain-specific PCK of qualified physics teachers focusing on the five PCK components: content knowledge, pedagogical knowledge, assessment knowledge, knowledge of students and curricular knowledge. Data were collected through the paper-and pencil PCK test that was responded to by 87 Physics teachers teaching the last two years of secondary school. Data were analyzed using the Extended Rasch Model and descriptive statistics. The results revealed that Physics teachers have a low PCK in general and low levels of PCK components, the lowest being content knowledge. The study recommends regular refresher workshops for qualified teachers focused on developing different PCK components, with more emphasis on content knowledge.  </style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">240-259</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%">Bo Chen</style></author><author><style face="normal" font="default" size="100%">Lijun Chen</style></author><author><style face="normal" font="default" size="100%">Xianhua Meng</style></author><author><style face="normal" font="default" size="100%">Minjie Yan</style></author><author><style face="normal" font="default" size="100%">Miaomiao Shen</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">DEVELOPMENT AND VALIDATION OF AN INSTRUMENT TO MEASURE UPPER-SECONDARY SCHOOL SCIENCE TEACHERS’ PERCEIVED PRACTICAL KNOWLEDGE ABOUT PRACTICAL WORK</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%">instrument validation</style></keyword><keyword><style  face="normal" font="default" size="100%">pedagogical content knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">perceived knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">Practical work</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%">February/2022</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://oaji.net/articles/2022/987-1647117534.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%">Teachers’ practical knowledge is closely related to teaching practice. The purpose of this research was to develop an instrument for assessing upper-secondary school science teachers’ perceived practical knowledge about practical work. The development of this instrument was based on five components in the conceptual framework of PCK about practical work: orientations of practical work, knowledge of curriculum materials in practical work, knowledge of students in practical work, knowledge of educational strategies for practical work, and knowledge of assessment in practical work. After the questionnaire was developed, 636 Chinese upper-secondary school science teachers participated in this research voluntarily. The results from exploratory factor analysis, correlation analysis and confirmatory factor analysis provided sufficient evidence for the construct validity of instrument. The high Cronbach coefficient indicated that the instrument had good internal consistency reliability. Finally, an instrument with six factors and 25 items was documented. The instrument would benefit science teacher educators and researchers. </style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">26-37</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%">Muhammet Usak</style></author><author><style face="normal" font="default" size="100%">Harun Uygun</style></author><author><style face="normal" font="default" size="100%">Muharrem Duran</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE EFFECTS OF SCIENCE TEACHERS' PEDAGOGICAL CONTENT KNOWLEDGE ON STUDENTS' ATTITUDES TOWARD SCIENCE AND THEIR ACHIEVEMENT</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%">attitudes toward science</style></keyword><keyword><style  face="normal" font="default" size="100%">pedagogical content knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">Science Achievement</style></keyword><keyword><style  face="normal" font="default" size="100%">SCIENCE teachers</style></keyword><keyword><style  face="normal" font="default" size="100%">teaching experience</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/2022/987-1662187302.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%">Pedagogical content knowledge (PCK) is one of the most important research topics in science teacher education. The purpose of this study was to investigate the PCK of science teachers with different teaching experiences and examine the effects of teachers' PCK on students' achievement and attitudes toward science. A mixed methods research design was used for the study. Participants were science teachers and their students from two middle schools. Interviews, observation forms, achievement tests, and attitude scales were used as instruments for data collection. Data were collected and analyzed using content analysis, descriptive and inferential statistics. The findings obtained from the quantitative and qualitative data showed some significant differences between teachers' PCKs according to their teaching experience. The results also showed that the PCK of a teacher with the least experience was lower than that of the other two experienced science teachers. The results indicated that experienced teachers who developed PCKs did not significantly impact student achievement and attitudes. Educational implications and recommendations for further studies are also provided.</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%">694-705</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%">'Maphole Marake</style></author><author><style face="normal" font="default" size="100%">Loyiso C.

There are calls for teachers to tap into their professional knowledge and develop beliefs that help them assist students comprehend the topic. To meet this challenge, teachers’ perceptions of their knowledge base for teaching force concepts should be probed because perceptions act as windows into teachers’ practices. This study, therefore, explored physics teachers’ perceptions of their knowledge base for teaching force concepts. Science teachers’ pedagogical content knowledge (PCK) frameworks were used to develop a questionnaire based on a 5-point Likert scale administered to 100 physical science teachers who were randomly selected from 54 schools in five districts in Lesotho. Data were analysed using descriptive statistics. The results suggest that, even though teachers reported positive views about their knowledge base, there is no correlation between sub-components of curricular knowledge. It is concluded that teachers should build the curricular knowledge by participating in collaborative activities. It is, therefore, recommended that studies that probe teachers’ actual knowledge of PCK constructs are executed, so that appropriate information is available when planning professional development activities targeting teachers’ PCK.</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%">651-662</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%">Peter Gustafsson</style></author><author><style face="normal" font="default" size="100%">Hans G.

In earlier studies, a validated tool, content representation (CoRe), has been used in teacher education to help pre-service teachers identify and promote pedagogical content knowledge in limited teaching sequences. In the present research the aim is to explore whether CoRe, when applied to an introductory university course in physics, can (i) promote the pedagogical content knowledge of the course as a whole and (ii) serve as an operative tool to identify problematic areas or areas that need further development in the course. The CoRe tool is based on given questions to be answered in relation to the “big ideas” of the course. In the present research, the questions have been answered by a lecturer and by using a content analysis of the answers several categories of development could be identified. For a specific category, the tool also provided information about what kind of development was necessary. The conclusion is that CoRe has a potential to be of service at higher education level, it can be applied to parts of a course as well as to a course as a whole, and it may provide a useful tool to help a lecturer in the development and planning of a course.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">56-63</style></section></record></records></xml>
