	abstract = {This research presents an integrative review about the methodological procedures adopted in the research of the Chemistry PCK, with the aim of identifying the data collection instruments used to explain the PCK in this field, seeking to observe its frequency of use and also contribute to the advancement of knowledge established by previous reviews. 89 articles published in magazines well evaluated by CAPES were selected, indexed to the Scopus (Elsevier) database. The treatment of the data was based on the technique of content analysis, resulting in six categories constructed a posteriori: a) period of publications; b) country of origin of the research; c) relationship to a specific topic; d) the teaching experience of the target audience; e) research approach and data collection instruments; and f) the use of PCK models as a theoretical framework. The results suggest a methodological predominance of a qualitative nature, with interviews, field diaries, observation of the practice, and questionnaires some of the most used instruments. Besides, a trend related to the specification of topics in the Chemistry discipline can be identified, as well as the lack of clarity regarding the variety of PCK models present in the literature and the failure to adopt these as a theoretical basis in most of the research studies analysed. There is also an express need to investigate the PCK of Chemistry teachers in practice in higher education since the results reinforce the scarcity of papers for this specific audience.},

	abstract = {Teachers often consider experimental activities to be fundamental to the teaching of scientific concepts. However, there are different views about their purpose in science classes; these views are linked to teachers{\textquoteright} different understandings of the construction of scientific knowledge. It was analyzed the views of 19 pre-service science teachers (PST) on the use of experimental activities in science classes. These PSTs were enrolled in the subject of science teacher training course of a Brazilian federal university. In their course work, the PSTS were organized into groups and they participated in a pedagogical activity during which they reported their views on two experimental scripts. They answered questions about how they would use these experiments in the future. The activity occurred in two stages: the first was before studying texts on the nature of science with an emphasis on the role of experimentation in the foundation of hypotheses; the second stage was after this. The data analysis was performed using the content analysis technique. The results suggest the importance of debates and deep themes in training courses for science teachers, so that experimental activities are not seen reductively and only as ways to motivate classes or to complement theory, but rather as potential aids in the construction of scientific meaning. },
