Statistical methods are indispensable to the practice of science. But statistical hypothesis testing can seem daunting, with P-values, null hypotheses, and the concept of statistical significance. This article explains the concepts associated with statistical hypothesis testing using the story of "the lady tasting tea," then walks the…

Student reasoning about cases of natural selection is often plagued by errors that stem from miscategorising selection as a direct, causal process, misunderstanding the role of randomness, and from the intuitive ideas of intentionality, teleology and essentialism. The common thread throughout many of these reasoning errors is a failure to apply…

Many students have very robust misconceptions about natural selection, stemming from intuitive theories that form a child's earliest understandings of the natural world. For example, students often imagine that species evolve in response to environmental pressures that cause a need for change and that all individuals in the population…

This paper presents an activity that engages students in model-based reasoning, requiring them to predict the behavior of the trp and lac operons under different environmental conditions. Students are presented six scenarios for the "trp" operon and five for the "lac" operon. In most of the scenarios, specific mutations have…

Describes methods used by scientists to investigate the past. Explains the scientific model existing in textbooks and methods for studying evolutionary history. (Contains 30 references.) (YDS)

Cites five misconceptions related to the concept of belief which affect if and how evolution is taught. Suggests that the words 'believe' and 'accept' are used interchangeably by scientists. Discusses each of the misconceptions in detail. (Contains 33 references.) (DDR)

Discusses issues regarding evolution instruction in public schools and focuses on misconceptions such as the use of the word "belief", lack of evidence for theories of evolution, and the belief that teaching evolution as fact is proselytizing students. Presents teaching approaches to the topic of evolution. (Contains 33 references.) (YDS)

Focusing on specific modes of evolutionally inquiry is important for students to achieve a mature understanding about evolutionary biology. Presenting evolution as rhetoric of conclusions would only confuse the minds of students.

This book is designed to assist those who work with non-English dominant students by providing resource information relevant to second language teaching and learning. The articles in the series encompass both theory and practical learning techniques in six general topics. Five articles concerning testing are presented in the fourth volume of this…
