Parts Of The Whole: Teaching Quantitative Reasoning In The Predator-Prey Model, Dorothy Wallace
Numeracy
The classical predator-prey equations are in nearly every differential equations text and mathematical biology text. Usually they are presented fait accompli, leaving the student to analyze them or play with a computer program. Here we show that the process of fully understanding where these equations come from and how they are derived provides numerous opportunities to teach or reinforce quantitative reasoning skills necessary to future scientists. This example is used to invoke logic, systems thinking, causal reasoning, understanding functions of one or more variables, quantities versus rates of change, proportional reasoning, unit analysis, and comparison to data.

Australian Journal of Teacher Education
The aim of this study is both to determine the perceptions of pre-service science teachers towards the concepts of entrepreneurship and entrepreneurial characteristics and to investigate the perceptions of pre-service science teachers regarding transferring the entrepreneurial characteristics to students. This study is designed as a qualitative study and a phenomenological research approach is used. A total of 12 pre-service science teachers from grades 5 to 8 participated in the study. Data were gathered through the use of semi-structured interviews. The data were evaluated through both descriptive and content analysis. The results show that the perceptions of the 12 …
