A textbook model of a contagious disease, the dynamics of which are represented by the SIS epidemic model with saturating treatment, is considered. I show that this model, as originally formulated, is not dimensionally consistent. The model can be fixed by including a dimensional constant [alpha] of value one (with units individuals[superscript…

Research from the fields of science representation, genre pedagogy and disciplinary literacy for adolescents indicates that achievement for students, including those from linguistically diverse backgrounds, will improve if they engage with the meaning-making conventions of disciplinary texts, but there is no current agreement on the nature of…

Internationally, the practicum is a cornerstone of initial teacher education in preparing pre-service teachers to enter the teaching profession. This edited collection expands theory and research in pedagogies of practicum by examining different ways teacher education programs across the globe experienced, modified, and innovated the practicum in…

Creativity is an important twenty-first century skill often overlooked in higher education curricula, particularly in the sciences. Students need opportunities to practice and demonstrate their creativity and gain an awareness of the importance of such skills to enhance their graduate capabilities. One way is to embed creativity into course…

DNA barcoding is increasingly being introduced into biological science educational curricula worldwide. The technique has a number of features that make it ideal for science curricula and particularly for Project-Based Learning (PBL). This report outlines the development of a DNA barcoding project in an Australian TAFE college, which also combined…

This paper investigated the use of term recall and recognition tools for learning terminology and concepts in a senior biology classroom. The paper responded to a set of research questions from a teacher researcher perspective, making use of data collected from the teacher researcher's classrooms over several years, based on the implementation of…

A variety of practices and specialised representational systems are required to understand, communicate and construct molecular genetics knowledge. This study describes teachers' use of multimodal representations of molecular genetics concepts and how their strategies and choice of resources were interpreted, understood and used by students to…

An action research study was designed to evaluate the effectiveness of providing metacognitive support to enhance Year 9 students' metacognitive capabilities in order to better understand science concepts related to light, environmental health, ecosystems, genetics, ecology, atoms and the Periodic Table. The study was conducted over three years…

Optional (non-assessed) learning activities are a learning tool that may help students achieve their desired grade, or help students with lower levels of previous experience in the topic. This study examines the implementation of, and outcomes from, two optional activities, one online and one paper-based. The activities complemented the lectures…

A blended approach encompassing problem-based learning (PBL) and structured inquiry was used in this laboratory exercise based on the congenital disease Osteogenesis imperfecta (OI), to introduce commonly used techniques in biomolecular analysis within a clinical context. During a series of PBL sessions students were presented with several…

Background: The ubiquity, availability and exponential growth of digital information and communication technology (ICT) creates unique opportunities for learning and teaching in the senior secondary school biology curriculum. Digital technologies make it possible for emerging disciplinary knowledge and understanding of biological processes…

Socioeconomic status at the individual- and school-level are positively related to literacy achievement in all English-speaking countries. The components of socioeconomic status -- income, parent education and parent occupation -- are each statistically significant predictors of school literacy achievement but they are primarily a proxy for more…

The purpose of this research was to determine whether teaching argumentation to high school biology students improved their argumentation skills, informal reasoning, and genetics understanding. Using a quasi-experiment with mixed methods of data collection, five teachers participated in professional learning on argumentation and socioscientific…

With new technologies developing so fast, it is difficult for students and teachers alike to keep up to date. Add into the mix skewed media reporting, some creative science fiction films and the unregulated world of the internet, and it becomes increasingly hard to separate fact from fiction. As Australia's largest funding body for stem cell…

The realisation to integrate science, ethics and morality is recognised with growing impetus in recent years (as noted with introducing the Australian Curriculum "Science as a Human Endeavour" strand), to develop sophisticated epistemologies of science, which includes an appreciation of the social context including ethical thinking. To…
