Studies in astronomy education have shown that socio-cultural factors combine with everyday human experience to create learning difficulties that are unique to this field. The history of astronomy also shows a complex link between science and religion. The foundations of modern astronomy lie in religious beliefs and practices, but over time, in the West, as science grew ever more powerful in explaining the apparently mechanistic processes of nature, the beliefs and understanding associated with scientific explanations came into conflict with those of the Christian church. In Africa, Western religious and scientific beliefs were brought by the missionaries, and imposed onto already existing beliefs systems. From colonial times to the present, Western knowledge has been privileged over local knowledge in African formal schooling. Little recognition has been given to the learning difficulties that may be caused in situations where the knowledge system taught at school is different to that imbibed through home and culture. The difficulties of epistemic access have been highlighted through the development of socio-cultural constructivist theories of learning. This study, which is based on the sociocultural constructivist theories of cultural border crossing and collateral learning, represents an investigation of the learning difficulties experienced by South African first year university students who study a compulsory course in basic astronomy called 'The Earth in Space'. The sample was thus a convenience sample, made up of 191 students who took the course between 2000 and 2004. The investigation was carried out using a pre-instruction questionnaire to record the precourse knowledge of the students. The questions that were asked focused on knowledge related to some of the key concepts in basic astronomy, such as an understanding of the nature of stars, the rotation and revolution of the earth and the phases of the moon. These questions had the dual purpose of benchmarking South African students' knowledge of the scientific explanations for these phenomena against similar international studies, as well as establishing the prevalence of cultural or traditional ideas held by these students. After the course had been completed, a post instruction questionnaire was used to establish students’ views on the difficulties they had experienced in learning in the course. This was followed up by semi-structured interviews with 25 of the students. The data obtained from the questionnaires were analysed using two methods: the first used a deductive coding system where the students’ responses were allocated to chosen categories, i.e. whether they conformed to the explanations of Western Modern Science or to cultural knowledge and beliefs, or both. The second method used a computer software programme, Atlas.ti, where each statement made by the student was recorded and coded, leading to an inductive, fine-grained analysis of their responses. The results from the pre-instruction questionnaire indicated that South African students display similar poor levels of knowledge in this field, to students from other Western and non-Western countries. The explanation for this lies in the fact that understanding the scientific explanations requires the ability to think abstractly, and to be able to construct complex mental models, in situations where the processes involved run counter to normal daily experience. However, the explanations given by the South African students also indicated that there were epistemological and ontological issues, related to conflicting beliefs in terms of culture and religion, which exacerbated the barriers to border crossing in this field. However, the data indicated that students did not find it as difficult to cross the barriers created by cultural or traditional beliefs as those caused by fundamentalist Christian beliefs. The biggest obstacle to learning related to conflict between creationist and scientific accounts of the formation of the Earth and Universe. While this is not unusual, as shown by studies carried out in the United States, where religious students are also affected by the apparent conflict between Christianity and science, the most significant finding of this study related to the existence and extent of this conflict in Black African students. In post-1994 South Africa, the revision of the national education system has resulted in a science curriculum that recognizes 'other ways of knowing'. These refer specifically, however, to Indigenous Knowledge Systems (IKS) rather than religious beliefs. The curriculum does not acknowledge that African ontology is religious. It also does not recognize the duality of this ontology in terms of African Traditional Religion and Christianity, which is the stated religion of the majority of Black South Africans. The findings of this study indicate that because of the nature of African philosophy, religious ways of knowing need to be explicitly acknowledged as one of the 'other ways of knowing'. Such acknowledgement by science teachers and lecturers would help to prevent these different knowledge systems from being discarded or compartmentalized, which was found to lead either to the promotion of scientism, or to the preclusion of meaningful engagement with science.

A organização da sociedade atual acontece em decorrência dos encontros entre culturas, sejam por meio de tragédias naturais, guerras mundiais, diásporas, reconfiguração de fronteiras ou da hibridização cultural. Nessa perspectiva, o objetivo desta pesquisa é investigar a construção da multiplicidade do Ser de fronteira a partir da perspectiva da escritora chicana Gloria Anzaldúa e do amazonense Milton Hatoum nas narrativas Borderlands/La frontera: The New Mestiza (1987), e Dois Irmãos (2000), respectivamente. Partindo das questões identitárias, o caminho para a análise das narrativas transita pelo espaço ficcional na intenção de evidenciar os deslocamentos e os fluxos migratórios das personagens como articuladores para compreender as feridas abertas nos espaços de fronteira. No decorrer da investigação foi possível ressignificar a fronteira como locus da diferença cultural e fragmentação para contrapor a ideia de que os lugares fronteiriços são fixos ou funcionam com divisores de sistemas culturais. Para desenvolver o trabalho, utilizo os métodos comparatistas e de aporte teórico da corrente culturalista. Uso os conceitos-chave de Walter Mignolo sobre a colonialidade do saber e de Stuart Hall e Homi Bhabha sobre as identidades heterogêneas. Na corrente filosófica, Jacques Derrida, com a teoria desconstrucionista, e Gilles Deleuze e Félix Guattari, com o rizoma e a teoria dos agenciamentos. Esse aporte é o fio condutor do debate sobre a modernidade tardia e da diferença cultural, tendo em vista espaços elaboradores de sujeitos marginalizados, periféricos, excluídos e silenciados. Sendo assim, a negação da postura essencialista, a partir da leitura das obras, serve de estratégia analítica e de compreensão da ferida aberta como espaço da multiplicidade dos sujeitos em regiões de fronteira. / Nowadays society’s structure is built upon/on encounters between cultures, natural tragedies, world wars, diasporas, reconfiguration of borders and cultural hybridization. Thus, the aim of this research is to investigate the construction of the multiplicity of the Frontier Self as it is through the approach of the Chicano writer Gloria Anzaldúa and in the approach of the Amazonian writer Milton Hatoum in Borderlands/La frontera: The New Mestiza (1987) and Dois Irmãos (2000), respectively. Considering the identity issues, the analysis of the narratives transits/moves/focuses on through the fictional space to highlight the displacements and the migratory flows of the characters as articulators in order to understand the open wounds in border spaces. Therefore, during the research, it was possible to re-signify the frontier as a locus of cultural difference and fragmentation to counteract the idea that frontier places are fixed or function as divisors of cultural systems. To develop this work, I apply comparative and theoretical methods within the culturalist approach as well as the key concepts of Walter Mignolo on the coloniality of knowledge, and Stuart Hall and Homi Bhabha on heterogeneous identities. The denial of the essentialist position, based on the reading of the works, serves as an analytical strategy and understanding of the open wound as the space of the multiplicity in border regions.
