The “Species” Concept as a Gateway to Nature of Science

The nature of science (NOS) is a primary goal in school science. Most teachers are not well-prepared for teaching NOS, but a sophisticated and in-depth understanding of NOS is necessary for effective teaching. Some authors emphasize the need for teaching NOS in context. Species, a central concept in biology, is proposed in this article as a concrete example of a means for achieving increased understanding of NOS. Although species are commonly presented in textbooks as fixed entities with a single definition, the concept of species is a highly discussed one in the science and the philosophy of biology. A multitude of species concepts exist, reflecting both the views and interests of researchers and their utility in different organism groups. The present study serves to address the following questions: How do textbooks in Norwegian primary and lower secondary schools present the concept of species? Can inquiries into the concept of “species” serve to highlight aspects of NOS? A review of the available literature on species and species concepts in school is also performed. In the schoolbooks, the biological species concept is commonly used as the main definition, whereas the morphological species concept is represented by additional remarks of similarity. The potential and pitfalls of using the species concept for teaching NOS are discussed, with NOS being discussed both as a family resemblance concept and as a consensus list. Teacher education is proposed as a starting point for inducing a more sophisticated view of biology into schools.     

Beyond the ‘good teacher’: guiding pre-service teacher reflections on culturally diverse students

This article explores how reflective practice may be facilitated among pre-service teachers preparing to teach in culturally diverse classrooms. The significance of the mentor teacher’s ability to reveal her/himself as a reflective practitioner in order to promote student reflection is well documented. The article specifically addresses one teacher educator’s approach to offering mentor support with a focus on reflective practices related to cultural diversity. She explores how her ethnographic doctoral study on the classroom participation of adult South Sudanese students in different Australian learning environments has informed her own practice as a teacher, and ways in which her teaching philosophy and values were influenced by the sustained reflection needed to complete the study. By making explicit an aspect of her reflective practice, she aims to add to the growing body of literature on how to engage pre-service teachers meaningfully in reflection on their own classroom practice, especially in relation to teaching to diversity.
