Thus, it has acted as a new playmaker in recognizing the importance of education and social justice. As stated by Usak et al. (2020), we, as educators, should pay more attention to the development of students’ awareness and scientific attitudes. Thus, they are able to think, understand, decide and make an action about any urgent event or &quot;forced&quot; transition, i.e., the pandemic process (Rodgríguez et al., 2021). Unfortunately, the COVID-19 pandemic seems to have generated a climate of fear for scientific advances and mass vaccination as well as regulations on lockdown, socialization, and hygiene. </style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Editorial</style></work-type><section><style face="normal" font="default" size="100%">694-699</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%">Sarah Bansilal</style></author><author><style face="normal" font="default" size="100%">Angela James</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">PHYSICAL SCIENCE TEACHERS’ PERCEPTIONS OF AN ADVANCED CERTIFICATE IN EDUCATION</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%">pedagogic content knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">physical science teachers</style></keyword><keyword><style  face="normal" font="default" size="100%">professional development</style></keyword><keyword><style  face="normal" font="default" size="100%">teacher beliefs</style></keyword><keyword><style  face="normal" font="default" size="100%">teacher confidence</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%">April/2016</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://journals.indexcopernicus.com/abstract.php?icid=1203601</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">70</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%">Advanced Certificate in Education programmes was offered by many South African universities to provide opportunities for teachers to upgrade their positions. The purpose of the study was to explore Physical Science teachers’ perceptions of their professional development. In this study we considered three domains of professional development which are content knowledge, pedagogic content knowledge and teacher beliefs and attitudes. This study used a mixed method approach using the form of an embedded design. The study was conducted with 156 students enrolled in an ACE Physical Science programme. The teachers stated that their content knowledge and pedagogic content knowledge had not only improved, but also their engagement with actual laboratories, and conducting experiments contributed to their teaching experiences. Hence, their self-confidence of physical science teaching evolved. The authors recommend that the ACE programme should also include a mentoring system with teaching practicum via school leadership and subject advisers.</style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">21–33 </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%">Andrea   C.

Though all stakeholders play critical roles in PDs, the author focuses on the larger system that supports the PDs. As such, this research study focuses on the PD results, but also on the explanation of the systemic nature of the PDs studied. Partnerships, including building of relationships, are explored in that system. In this mixed methods study of two K-12 teacher PDs (n=31 and 19 total PD days), conducted in the western United States, the author utilizes quantitative and qualitative data collection methods to reinforce quality PD practices and suggested strategies. Results indicate that 90% of the K-12 teachers were highly engaged in the STEM content and partnership building. Pre to post K-12 teacher perception scores regarding astronomy use in STEM content courses showed noteworthy improvement from 16% to 84%. Furthermore, K-12 teacher perceptions regarding creation of partnerships and collaborations rose from 26% to 90%. Other findings showcase themes of reflection, collaboration, STEM integration, and inquiry as well as a need for partnership building time. Overall, when the K-12 teachers worked together in a structured PD over an academic year (2014-2015) for a selection of 19 days (13 summer days and 6 Saturdays during the academic year) partnerships were formed and provided added organization for the PD system. Faculty/PD team communications and continuous K-12 teacher support were also critical factors for systemic PD success.
