Abstract

The reef ecosystems present great diversity of fauna and flora, and this environment considered one of the richest on the planet, both in number of species and specimens. Alia is also the scenic beauty and the leisure and tourism options that provide for man. The motivation of choosing this theme was due to the fact the city of Maceió is situated on the coast, where there are beautiful reef formations. This work was developed with the objective of providing students of a public school in the city of Maceió, Alagoas State, the construction of the critical consciousness, to understand the importance of preserving the reef ecosystems. Thus also sought to know the perception of students on the theme of preservation and conservation of ecosystems, with emphasis on the reefs, making them aware about the complexity of interrelations in a reef environment with the creation of a book- game, with the scientific field Ecosystems reef, which has resulted in the educational product. The target audience of the research was constituted by a group of students of the 2nd year of high school in a public school, located on the outskirts of the city of Maceió, Alagoas. The dissertation was divided into three articles, which tried to assess how much students know about reef ecosystems before, during and after the dialogic lectures. In the first article was addressed a discussion of issues related to the teaching of Science, related to information technology aiding in learning, it was also a questionnaire with five essay questions to assess students' prior knowledge about the reef ecosystems. In the second article classes were planned in interactive way, to serve as teaching strategies to student learning and is considered the teacher intervention. Before and after these activities was a questionnaire with five questions each objective, different from each other as the issues. The third paper presented a discussion on the use of playfulness in the teaching of scientific concepts, particularly relating to reef ecosystems, when they were given the necessary explanations for students to use the bookgame. the last two questionnaires of this research were then applied a relative evaluation of the use of book-game, five objective questions and space for comments, while the other dealt with the concept of scientific terms related to reef ecosystems, containing five objective questions and a discursive. The results of three articles showed that the methodology favored learning because it was found a luggage prior knowledge of students through diagnostic evaluation, even if insufficient for the full understanding of the content. It was also verified the expansion of knowledge and awareness of students about the topic discussed after planning and interventions in the form of dialogued classes. Finally, the book-game has been rated by students as an excellent teaching tool for the presentation of scientific themes, such as reef ecosystems. There was encouragement for students to realize and appropriating the importance of the subject matter, with different classes of methodology presentation and thus the acquisition of knowledge transmitted, especially the aspect of preservation of reef ecosystems in a city located by the sea.
