The teacher has 20 years teaching experience in the central Australian school in which she currently teaches. The majority of students in the school are Indigenous, several come from overseas and many learn English as an additional language. The teacher believes that real life experiences assist these students to make connections in their learning and reinforce the technical language of the discipline. Previously in her year 7 Science class, she has introduced students to the diversity of organisms and the usefulness of classification in organizing this diversity. Following the excursion to the Reptile Centre, she articulates how she will extend the students new knowledge to include global changes and their impact on the local environment.
