In this paper we use Astronomy as background and motivating element so that we approach concepts of optics, waves and contemporary Physics, using the cooperative learning Jigsaw methodology. Astronomy insertion is a potential learning motivator and through it we aim to construct a potentially significant didactic material. Therefore, we developed activities that use the concept of color and spectroscopy, which were presented concomitantly with traditional topics present in the curriculum. With the Jigsaw method, we have established collaborative groups for practical and theoretical activities. We emphasize that all of them have been idealized so as not to require the use of computers. The final products include a didactic sequence and materials for its application: 15 thematic cards for the Jigsaw application and two activities, one on spectra calibration and another on the Doppler effect in galaxies, where it is possible to observe the shift to red of lines in galaxies spectra obtained from astronomical databases. About the calibration activity, we provided all steps for the obtaining and treatment of the home spectra (including tutorial videos) and how to obtain standard values data spectral lines by a technical rules institute of the United States, aiming at replicability. During the lessons we promote the comparison between spectra coming from different light sources in order for us to discuss with the students stars light nature. This proposal’s three classes occurred in a public school in Aracaju city, Sergipe. Through students answers in the pre-test and in the post-test, both made without statistical purposes, as feedback to our practice, it was possible o notice improvement indications in correct answers quantity made possible by the activities described here, which suggests that the Jigsaw method is possible, if we do not get slightly better results through meaningful learning, at least the same learning occurs with a great gain to the interaction process among all the participants. These tests provided data regarding our practice, making it possible the discussion about methodological corrections. We could realize that the Jigsaw method, through its proposed social interaction, has demonstrated to be potential facilitator of significant learning and to aggregate learning process involved individuals.
