Acceptance of the theory of evolution by high school students in Rio de Janeiro, Brazil: scientific aspects of evolution and the biblical narrative

Abstract

ABSTRACTTeachers face numerous challenges when teaching evolution, especially students’ creationist beliefs and religious doctrines. Although this is a subject more studied in the USA, recently studies have shown resistance towards evolution by Pentecostals groups in Brazil. In this research, we investigated the acceptance of evolution and creationism by high school students in Rio de Janeiro, Brazil. We applied questionnaires to students of two public high schools in the state of Rio de Janeiro, one in the capital and the other in Nilopolis, in the metropolitan region (N = 541). Principal Components Analysis was used and two indexes of acceptance of evolution were created: (i) Acceptance of the Scientific Aspects of Evolution Factor (SA) and (ii) Acceptance of the Biblical Narrative for the Origin and Development of Living Beings Factor (BN). Data indicate that Pentecostal students have a lower mean for SA and greater for BN in comparison to other religious groups. Moreover, a model of linear regression was developed for each factor. Only for BN, being Pentecostal was statistically significant (p < 0.05), which means that Pentecostals may accept scientific aspects of evolution, even though they accept them less than the others. Following other authors, we argue that it is essential that teachers be aware of the religious diversity that exists in the class and make a clear distinction between religious and scientific knowledge, in order to promote the understanding of scientific theories and avoid attempting to change religious beliefs.
