The research design followed a qualitative multiple case study model. Data were gathered through semi-structured interviews, written reflections, and participant observation journal notes. Main findings highlight the way specific components of the thesis linked to stages of the action research study contributed to developing certain types of knowledge integral to pedagogical content knowledge. Knowledge of the students was highly impacted by the needs analysis and the design and implementation of the intervention. In terms of pedagogical knowledge, building the state of the art and theoretical framework along with the intervention clarified and further developed knowledge of teaching methodologies and strategies. Subject matter knowledge was highly impacted by the theoretical framework and the socialization opportunities. Establishing the setting of the study contributed to further understand the constraints and affordances of their teaching contexts. Overall, this action research study became an insightful experience that helped participants promote effective classroom practices to address their students’ needs. </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%">533-552</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%">Ijeoma Chidinma Ogbonnaya</style></author><author><style face="normal" font="default" size="100%">Andile Mji</style></author><author><style face="normal" font="default" size="100%">Olivia Neo Mafa-Theledi</style></author><author><style face="normal" font="default" size="100%">Beatrice Ngulube</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">ECONOMICS TEACHERS’ USE OF TOPIC SPECIFIC PEDAGOGICAL CONTENT KNOWLEDGE IN TEACHING MARKET DYNAMICS</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">content knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">economics teachers</style></keyword><keyword><style  face="normal" font="default" size="100%">market dynamics</style></keyword><keyword><style  face="normal" font="default" size="100%">pedagogical content knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">topic specific pedagogical content knowledge</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2020</style></year><pub-dates><date><style  face="normal" font="default" size="100%">June/2020</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://journals.indexcopernicus.com/search/article?articleId=2537295</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">78</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%">The poor learners’ understanding of specific topic ‘Market Dynamics’ (MD) is a concern in South Africa secondary schools and so it is globally. Many researchers and education stakeholders in South Africa point to the need to use TS-PCK to improve learners’ understanding of MD. This research aimed to examine economics teachers’ teaching of Market Dynamics (MD) in order to understand how the teaching and learning of MD could be improved using topic Specific PCK.  Using Mavhunga’s TS-PCK as the theoretical framework. Two TS-PCK components were examined in the research namely, content knowledge (What is that makes a topic difficult to teach?) and representations were used to gain an in–depth understanding of teachers’ use of TS-PCK in teaching MD. It was a descriptive case study design. Purposeful samples of three economics teachers of 10th, 11th and 12th grade were selected. A semi-structured interview consisting of 18 items was used to generate data for the research while a qualitative data analysis technique, namely thematic analysis was used to analyze the data generated. The results showed that the three economics teachers sampled for the research were able to use their TS-Content Knowledge adequately in different Content Knowledge domains to understand what makes a topic difficult to teach or learn. The result also showed that the participating teachers identified difficult areas that are challenging to teach in the topic of MD but were unable to explain and give cogent reasons why those areas were challenging for learners to understand. Further results on teachers’ use of TS-PCK based on ‘representations’ revealed that the teachers effectively used analogies and examples in teaching market dynamics but struggled to find activities to illustrate some of the concepts of market dynamics. The research recommends that economics teachers should be provided with more structured opportunities to help develop their topic specific pedagogical content knowledge of the school level content as part of their professional development.    </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%">371-393</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%">Brunno Carvalho Gastaldo</style></author><author><style face="normal" font="default" size="100%">Paula Homem-de-Mello</style></author><author><style face="normal" font="default" size="100%">Sérgio Henrique Leal</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE EFFECT OF TEACHER INSTRUCTIONS ON PRESERVICE TEACHER’S DEVELOPMENT OF PEDAGOGICAL CONTENT KNOWLEDGE</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">knowledge integration</style></keyword><keyword><style  face="normal" font="default" size="100%">pedagogical content knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">pre-service teacher</style></keyword><keyword><style  face="normal" font="default" size="100%">teacher formation</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2016</style></year><pub-dates><date><style  face="normal" font="default" size="100%">October/2016</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://journals.indexcopernicus.com/abstract.php?icid=1224698</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">73</style></volume><pages><style face="normal" font="default" size="100%">Discontinuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Trying to understand the knowledge base for teaching, the Pedagogical Content Knowledge (PCK) was proposed as the main teacher’s knowledge. It amalgamates the specific knowledge and it is the difference between a teacher and a specialist. It can be both personal, deriving from practice, and canonical, which is cultural accumulation of what makes a good teacher. To acquire the last, preservice teachers (PSTE) take university classes, where theoretically their apprenticeship could be facilitated by the university teacher. Thus, it is important to understand how the university teacher best exerts his influence on PSTEs. In this paper, we show the impact of the university teacher’s interventions in the development of PCK based on analysis of a course taught to chemistry PSTE. The research was conducted in a qualitative approach, in a case study strategy. The classes from a chemistry teacher’s course from a federal university in São Paulo, Brazil were recorded for four months, to follow the development of the PCK. Qualitative forms of assessing the PCK, as CoRe, were used, and the tasks given by the teacher were collected to support the analysis. Our results show that the students’ knowledge integration responds to teacher interventions, particularly when those were customised to each individual. When the intervention was made by means of written exercises the influence on PSTE was lower than orally and when made by peers even lower or null. Being so, teacher’s interventions could be considered an INUS condition for the development of PCK in those students.</style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">45-61</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%">Carmen   Fernandez</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">KNOWLEDGE BASE FOR TEACHING AND PEDAGOGICAL CONTENT KNOWLEDGE (PCK): SOME USEFUL MODELS AND IMPLICATIONS FOR TEACHERS’ TRAINING</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">knowledge base of teaching</style></keyword><keyword><style  face="normal" font="default" size="100%">pedagogical content knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">professional knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">Teachers’ education</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2014</style></year><pub-dates><date><style  face="normal" font="default" size="100%">July/2014</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2015/457-1421876658.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">60</style></volume><pages><style face="normal" font="default" size="100%">Discontinuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In recent years the profession of teaching has reached a maturity to the point of being considered a producer of own knowledge necessary to the practice. The teacher is no longer seen as a technician, but as an intellectual actor and the specialized literature advocates teaching as a profession, and it recognizes that the teacher has “knowledge base”, a set of skills that are developed during his teaching activity. The Pedagogical Content Knowledge (PCK) is a concept that seeks to represent the teachers’ professional knowledge and it has been widely used in the literature about teachers' knowledge. It has proved a fruitful model for investigations aimed to document the knowledge that makes one a good teacher. Despite the relevance that the PCK is, the consensus on what is the PCK is still far from being achieved and many researches propose different models and concepts for the PCK, sometimes conflicting. Many works brings the PCK and speak of it as if it were a clear concept and do not clarify which model / conception are using, which makes investigations on the PCK difficult and ends up attracting a lot of criticism. Thus, this study aims to look critically at the various models proposed in the literature most used and point differences and similarities so that an overview can be built with more insight and analyze their use and validity. The study will also present some ways to have access to PCK and the relation between PCK and teacher education is also discussed.</style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">79-100</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%">Marina Miyuko Akutagawa Tacoshi</style></author><author><style face="normal" font="default" size="100%">Carmen   Fernandez</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">KNOWLEDGE OF ASSESSMENT: AN IMPORTANT COMPONENT IN THE PCK OF CHEMISTRY TEACHERS</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">chemistry teacher education</style></keyword><keyword><style  face="normal" font="default" size="100%">knowledge base of teaching</style></keyword><keyword><style  face="normal" font="default" size="100%">pedagogical content knowledge</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2014</style></year><pub-dates><date><style  face="normal" font="default" size="100%">December/2014</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2015/457-1423570850.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">62</style></volume><pages><style face="normal" font="default" size="100%">Discontinuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Assessment of learning plays a central role in the teaching-learning process, and it has been extensively investigated due to the recognized necessity of adjusting didactic models to the new curricula and social demands. The knowledge of assessment is considered one of the components of pedagogical content knowledge (PCK) by some authors and for other authors is considered one component of the knowledge base for teaching. It is also recognized the strong link between knowledge of the educational ends, goals, purposes and values and the knowledge of assessment procedures. In this work, results focused on ten chemistry teachers are presented with the main goal of assessing and describing the knowledge of assessment practices and its close relationship with the purposes and educational aims. The results of the current study are based on semi-structured interviews, schools’ educational projects, questionnaires, evaluations and teacher lesson plans. The data suggest that there exists an inconsistency in the discourse regarding general education and chemistry education. Although the discourse at all levels, including educational projects, planning and interviews, can be considered as innovative, in actual practice we observed a strong tendency toward the teacher-centered approach and summative assessment. The results show that, in general, the investigated chemistry teachers lack the intrinsic knowledge to elaborate questions that assess students´ higher-order thinking, to use assessment results to improve teaching and learning, to inform planning, and ultimately, to perform assessments for learning that regulate and promote the learning process, in line with their own beliefs regarding the objectives of chemical education. As a result, we can infer problems in other PCK components of these teachers.</style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">124-127</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%">Gildo   Girotto Júnior</style></author><author><style face="normal" font="default" size="100%">Carmen   Fernandez</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">FOLLOWING EARLY CAREER CHEMISTRY TEACHERS: THE DEVELOPMENT OF PEDAGOGICAL CONTENT KNOWLEDGE FROM PRE-SERVICE TO A PROFESSIONAL TEACHER</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">pedagogical content knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">teacher's knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">teacher’s professional development</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year><pub-dates><date><style  face="normal" font="default" size="100%">July/2013</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2014/457-1420055017.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">55</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In this study the aim was to investigate the development of Pedagogical Content Knowledge (PCK) of early career chemistry teachers. Two pre-service chemistry teachers were followed during a one-semester course and after a three-year period as formal high school teachers. The data involved teachers´ writings, recordings of lessons and reflections during the course. After three years, the same content lessons in an actual school environment were videotaped. The teachers were then interviewed using the videotapes for stimulated recall. The instruments Content Representation (CoRe) and Pedagogical and Professional-experience Repertoires (PaP-eR´s) were used to document and to describe teachers’ PCK. Analysis of discursive interaction patterns was performed during lessons. Data analysis was based on the components of teacher knowledge as described in the Morine-Dershimer Model. The development of PCK was enhanced during the pre-service teacher education through the experiences of planning and conducting interventions in the classroom and particularly during the reflection-on-action activities. Results after three years of professional experience revealed an improvement in these teachers’ PCK and highlighted the central role of the reflection process and practical experience. From the analysis carried out, it emphasized the need to act in these early years of professional experience through collaborative groups, supporting the reflection process and aiming to contribute more directly to the development of teachers' PCK.</style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">57-73</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%">Markus  Rehm</style></author><author><style face="normal" font="default" size="100%">Peter  Buck</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">HOW CAN ATOMS, THE FUNDAMENTAL OF CHEMISTRY, BE TAUGHT ADEQUATELY IN THE 21ST CENTURY?</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">approaches to teaching atoms</style></keyword><keyword><style  face="normal" font="default" size="100%">pedagogical content knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">understanding atoms</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year><pub-dates><date><style  face="normal" font="default" size="100%">November/2009</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2014/457-1399914243.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">17</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This paper is a systematic contribution to Pedagogical Content Knowledge (Shulman, 2004) on teaching atoms in Chemistry. We justify our normative starting points (we call them “axioms”) and proceed 
o from axiom #1 – science education’s foremost goal is comprehension, 
o to axiom #2 –comprehension can exclusively be achieved by an individual, be it the teacher or the learner, 
o then further to axiom #3 and #4 – on the part of the teacher, both her understanding of the subject matter (content) and of learning (its process and perspective) can be expected to lend considerable importance to the way she designs and organizes teaching &amp; learning situations in school science (axiom #3), – on part auf the learner teachers must presuppose a will to learn (axiom #4)),
o and finally come to axiom #5: Any teaching any design of teaching &amp; learning situations in school science must take concordant to contemporary science. 
In this justification process we discovered that the different understandings of comprehension found empirically by Helmstad (1999) correspond neatly to the different didactical approaches of teaching atoms, i.e. the particulate nature of matter. These findings enable both teachers and curriculum designers to make theoretically better founded choices.
