Mathematics is a key aspect of science but how mathematics can be successfully integrated in science teaching remains a vexing issue. That students often struggle with mathematics in science lessons, even when they have little problem with those ideas in mathematics lessons, has been a long-running concern for educators. One reason this the issue r...
