Researchers have been measuring how effective their professional development efforts have been for the development of teachers’ TPACK (Graham et al., 2009; Guzey &amp; Roehrig, 2009). So far research is based only on short-term courses, so longitudinal studies are needed to examine the TPACK development of teachers across time (Hoffer &amp; Grandgenett, 2012; Koh &amp; Sing, 2011). A two-year in-service training program of educational technology (60 ECTS), based on the TPACK framework, was developed at Tallinn University Haapsalu College to support in-service teachers to effectively embed ICT into their classroom teaching. The first group of teachers (n=20) enrolled in the program in January 2014. This paper reports some preliminary findings of a longitudinal action research, the main aim of which is to evaluate the impact of the in-service training program of educational technology on teachers’ TPACK. The key questions for this research were: how do teachers’ perceptions of their TPACK levels change after participating in the training program for a year; which of the seven knowledge domains of the TPACK framework develop more than others; what is the impact of different knowledge domains on teachers’ TPACK perceptions. The TPACK questionnaire developed by Schmidt et al. (2009) was used to measure in-service teachers’ self-assessments of their TPACK during the first meeting of the training program and at the end of the first academic year. The research results revealed increase in all the domains of the TPACK framework. There was significant development of the teachers’ TK and TPACK, but only limited growth in CK and PK. Strong positive correlations were found between TCK, TPK and TPACK in the post-course survey.</style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">18-28</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%">Edson  Rodrigues  Santana</style></author><author><style face="normal" font="default" size="100%">Agnaldo Arroio</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE USE OF AUDIOVISUAL APPROACH TO TEACH NATURE OF SCIENCE FOR IN-SERVICE NATURAL SCIENCE TEACHER’S 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%">cinema</style></keyword><keyword><style  face="normal" font="default" size="100%">in-service teachers</style></keyword><keyword><style  face="normal" font="default" size="100%">nature of science</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">December/2012</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2014/457-1419345940.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">50</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The nature of science is a subject recognized among researchers and curriculum proposals, however still find some problems, especially with regard to what teachers understand about the subject and the importance attributed to it. Another element in this discussion concerns the use of resource suitable for use in teaching and learning situations. Therefore we present a research outline still in progress which discusses the use of audiovisual and methodological support to discuss the nature of science, for that resource is being applied in an in-service education program in the Faculty of Education, University of São Paulo, Brazil. According to the preliminary results it can find some initial modifications, these enhanced by audiovisual feature tied to reflections that occur during the activities developed by 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%">90-100</style></section></record></records></xml>
