Organising Levels of Organisation for Biology Education: A Systematic Review of Literature

Many authors suggest an explicit reflection on the levels of organisation, based on known difficulties related to understanding biological systems. Yet, there is no scientific consensus on the characteristics of biological levels and the quality of their relationships. This review intends to present the state of the current discussion in order to establish an educational argumentation as a basis for the development of learning environments and teaching experiments in biology education. For this purpose, we conducted a systematic literature review. Three databases (BIOSIS, ERIC, Fachportal-Pädagogik) were searched for literature on levels of organisation. The papers were analysed by means of a qualitative content analysis based on the following research questions: (1) Which levels of organisation do the authors name? (2) How do the authors describe the levels of organisation? (3) How do the authors describe the relationship between different levels of organisation? (4) How do the authors describe the challenges of these levels for biological education? (5) How do the authors describe the benefit of these levels for biological education? Based on the results, we propose a system of levels that features the concept of zooming-in and makes the relationships between the levels explicit.

Using systemic functional linguistics to explore digital technologies in educational contexts

Over the last decade, technological innovation has led to new pedagogic sites, such as online discussion forums and virtual 3D worlds. In these sites students and teachers use language and other meaning-making resources to engage in educational argumentation. However, there have been few studies which have systematically explored the role of lexicogrammatical and other semiotic resources in the making of meaning in these contexts. This is because the main body of research underpinning claims around the affordances and limits of online argumentation is located within sociocognitive paradigms. By drawing on the tools of systemic functional linguistics and, where relevant, systemic functional-multimodal analysis, this article therefore offers a fresh perspective. I show how such tools can illuminate both the overarching textual shape and structure of online discussion forums and the ways in which meanings are made through language and other semiotic resources.
