Epigenetics is the study of how external factors and internal cellular signals can lead to changes in the packaging and processing of DNA sequences, thereby altering the expression of genes and traits. Exploring the epigenome introduces students to environmental influences on our genes and the complexities of gene expression. A supplemental…

The video game SPORE was found to hold characteristics that stimulate higher-order thinking even though it rated poorly for accurate science. Interested in evaluating whether a scientifically inaccurate video game could be used effectively, we exposed students to SPORE during an evolution course. Students that played the game reported that they…

This article recounts the story of the development of pangenesis, a principle proposed by Charles Darwin to describe the rules of inheritance and the source of new variation, two concepts vital to his proposal of evolution by natural selection. Historical accounts such as this are infrequently included in texts and classroom discussions but can…

Biotechnology is a cutting edge science/technology which impacts the community in many ways. For this and other reasons, it is important we encourage teachers to include biotechnology in the science curriculum. First, however, we need to know what hinders and encourages teachers. We surveyed the views of 88 high school science teachers. The …

Across the country, significant percentages of high school teachers are not convinced that evolution is a central concept to biology and/or are of the opinion that creation should be taught in public school science classes. Are these attitudes transferred from educators to their students? Unless educators address this kind of question, they will…
