Biology teachers’ conceptions about the origin of life in Brazil, Argentina, And Uruguay: a comparative study

. Teachers’ conceptions about the origin of life in three Latin American countries with contrasting levels of secularism were analyzed: Argentina (Catholic constitution), Brazil (formally secular but not in practice), and Uruguay (consolidated secularism). A European survey questionnaire was used and the interpretation of the results drew on Barbour’s four categories concerning the relationships of science and religion. A large majority of Argentinian and Uruguayan teachers were clearly evolutionist, even when believing in God (Independence or Dialogue category), with no difference be- tween Argentina and Uruguay. The majority of Brazilian teachers assumed a religious position about the origin of life, being creation- ist (Conflict or Independence categories) or evolutionary creationist (Dialogue or Integration categories). Differences of Brazilian teach- ers’ conceptions may result from the higher percentage of evangelicals and lower proportion of agnostics/atheists. Brazilian Catholic teach- ers were more creationist than their Catholic colleagues in Argentina and Uruguay. Distinct patterns were found, but further research is needed to understand possible classroom impacts.
