Perspectives on the Origins of Life in Science Textbooks from a Christian Publisher: Implications for Teaching Science

This paper presents the results of research regarding approaches to the origin of life featured in science textbooks produced by an Evangelical publisher. The research nature was qualitative with document analysis and an interpretive framework based on Epistemological Pluralism. Overall, the results indicate that there are four perspectives on the origin of life in textbooks under study. These perspectives do not distinguish scientific knowledge from religious knowledge but present a hybrid of scientific and religious knowledge. There are scientific inaccuracies in the perspectives, which emphasize biblical arguments over scientific arguments. Data analysis and conclusions take into account the central argument of Epistemological Pluralism about the importance of demarcation of science in relation to other knowledge systems and its consequences for learning science.     

The failure of a virtual social space (VSS) designed to create a learning community: lessons learned

The disappearance of physical social spaces from today's society is seen by some to be a modern phenomenon, resulting in isolation and lack of socialisation. In fact, this is always the case in distance education, due to geographical dispersion and disparate time schedules of learners. Very often, peer‐to‐peer socialisation in distance education only occurs as part of formal learning activities, or is just left to the student's own initiative. This situation is compounded by the modularity of Virtual Learning Environments (VLEs), forcing students to jump from one module space to another as they progress through a course. All discussion threads, conversations or record of previous dialogues are then lost. This paper reports on the design, development and extensive evaluation of a Virtual Social Space (VSS) conceived to address these problems and to support the creation of a learning community for a Continuing Professional Distance Education (CPDE) Masters in IT Management. An action research approach was adopted to establish student needs, design and develop the site and to explore it with students. Initially received with enthusiasm and perceived as a good idea by the students, the VSS was not entirely successful. This paper discusses how characteristics of this cohort had an impact on students’ perception and usage of this social space to create a learning community.     

The Contribution of Ethnobiology to the Construction of a Dialogue Between Ways of Knowing: A Case Study in a Brazilian Public High School

This paper reports results obtained in pedagogical interventions in a Brazilian public high school which aimed at promoting a dialogue between scientific and traditional knowledge in the context of biology teaching. The interventions were based on the use of a didactic material and teaching sequence elaborated on the grounds of school knowledge about botany, as presented in biology textbooks, and interviews with students who were also farmers, so as to gather data about their ethnobiological knowledge. Our goal was to develop and test resources that can offer support for teachers who wish to build a dialogue between different ways of knowing in multicultural settings. Our results indicate that the use of the didactic material and teaching sequence indeed created possibilities for a dialogue between the students’ ethnobiological knowledge and biology school knowledge. We observed some shortcomings in classroom practice, partly reflecting our very choice of subject matter to develop the teaching sequence. But the interventions also revealed important limitations that we regard as representative of problems that may generally make multicultural science teaching a hard goal to achieve. It was clear that important shortcomings were related to teachers’ difficulties to conduct a dialogue between ways of knowing in a science classroom, and, thus, called attention to the importance of introducing a multicultural dimension into teacher education. We also observed that the fact that students did not show much sensitivity towards dealing with cultural diversity was a factor constraining the success of the interventions. These results highlight the importance of proposing and testing teacher education initiatives aiming at preparing them to teach science in a culturally sensitive manner, and also managing classroom tensions and conflicts so as to make it possible an effective dialogue between different ways of knowing in a multicultural setting.
