JIGSAW METHOD AND WORKSHOP: ARTIFACTS FOR ADDRESSING ENVIRONMENTAL THEMES USING ADSORPTION FILTERS

Abstract

Chemistry teaching is often based on learning by memorization, which makes the content difficult to understand. One of the ways to make classes more interesting is by using experiments and active learning methodology. This work presents the application of the Jigsaw teaching methodology, and the development of a low-cost experiment, using accessible materials, which was presented by students in a workshop. The work was developed with students in the 2nd year of High School of a public school at the district of Cariacica, at Espírito Santo. The objective was to work on environmental issues, promoting learning based on an active methodology, and the production of adsorption filters, using the Jigsaw method. Green coconut mesocarp with different particle sizes, chitosan, and activated carbon were used as adsorbent materials, where the removal of gouache paint in water produced in a school environment was observed by visual analysis. Verification of learning was obtained through the application of a pre-test that showed the students' prior knowledge on the topic, and a post-test, verifying the acquisition of new concepts.
