Although the applications of nuclear technology benefit several fields, such as health, industry, agriculture, energy production, among others, its public acceptance is still reduced and there are various barriers to its use. A lack of assertive knowledge about this technology generates prejudice against its use. Prejudices may be explicitat the conscious levelor implicitoperating outside awareness. Nevertheless, either conscious or unconscious, prejudices interfere with behavior and attitudes. The experiences in the explicit and implicit memories can be transferred from one to the other; thus unconscious prejudices or associations may be modified by the explicit memory, that is, new knowledge may reduce or even reverse them. The teachers play a critical role for transforming education; however, for sharing balanced knowledge they must have a perspective without prejudices. This work aims to develop a neuroscience-based methodology through which implicit associations of Brazilian science teachers towards nuclear technology may be assessed and possible implicit prejudices may be changed by new knowledge. In order to identify implicit prejudices, specific implicit memory tests are required. The Implicit Association Test (IAT) was chosen for this work. By following the steps provided by the software FreeIAT, the IAT was customized aiming to compare the implicit associations of respondents towards nuclear and oil. A pretest with nuclear specialists (control group) and lay people was administered to check the consistency of the customized IAT. The Cronbach´s alpha was applied to measure the reliability of the test and showed good internal consistency. A 5-hour multisensory program for science teachers was designed and administered at the Instituto de Pesquisas Energéticas e Nucleares (IPEN). The IAT was administered at the beginning and at the end of the program and the results of the implicit associations were compared. After a six-month period, the IAT was re-administered to the same group of teachers to verify whether the implicit associations remained stable. This multisensory program was compared to a 12-week traditional teaching program with lecture classes held at IPEN for incoming post-graduation students. The multisensory program was effective for changing and maintaining the implicit associations of teachers towards the beneficial applications of nuclear technology, unlike the traditional teaching program with lecture classes. This work demonstrated that it is possible to break paradigms and prejudices. The multisensory program enabled an enriched knowledge about the applications of nuclear technology, that is, it promoted new experiences in the explicit memory, which modified the previous associations stored in the implicit memory. Therefore, the multisensory program has proven to be a successfu...
