Efforts to assess students' and teachers' understandings of nature of science have extended for over 50 years. During this time, numerous instruments have been developed that span the full range of assessments from the traditional to open-ended assessments with interviews. As one might expect, the development, use, and interpretation of these assessments have paralleled the scholarship on students’ and teachers’ understandings of nature of science. Consequently, such assessments have evidenced the same challenges and obstacles seen in the general research literature. (...) This chapter will provide a rationale for the importance of teaching, and assessing, nature of science as well as a discussion of the construct. A comprehensive review and a critical analysis of the various assessments are also provided. Finally, an in-depth discussion of the contemporary issues regarding nature of science and its assessment is provided along with cautions regarding the future direction of nature of science assessment.

Many introductions to this field start with the problem of justifying scientific knowledge but Alexander Bird begins by examining the subject matter, or metaphysics, of science. Using topical scientific debates he vividly elucidates what it is for the world to be governed by laws of nature. This idea provides the basis for explanations and causes and leads to a discussion of natural kinds and theoretical entities. With this foundation in place he goes on to consider the epistemological issues of how (...) science arrives at knowledge, favouring a treatment of scientific reasoning based on inference to the best explanation. Drawing on contemporary work in epistemology, Bird argues that scepticism about induction should not be a problem for science and examines the consequences of this position for controversies surrounding the ideas of scientific progress and scientific revolution. Bird's insightful treatment makes Philosophy of Science an ideal text for undergraduate courses. The guides to further reading provided in each chapter help the reader pursue interesting topics and facilitate the use of the book in conjunction with primary sources. (shrink)

This chapter briefly traces the history of nature of science (NOS) orientations in science education, notes some differences in the way NOS is defined and in arguments used to justify its inclusion in the school science curriculum and acknowledges the centrality of NOS to recent curriculum and research initiatives based on scientific argumentation, modelling and consideration of socioscientific issues (SSI). Some critical scrutiny is directed towards the so-called consensus view of NOS and whether it adequately and appropriately represents the diversity (...) of approach across the different subdisciplines of science. Of course, serious consideration of curriculum initiatives inevitably leads to questions concerning assessment policy and practice. Key issues relate to the philosophical adequacy and psychometric robustness of questionnaires, interviews, observation studies and approaches utilizing students’ drawings and stories and how best to record and report findings. After a brief discussion of some important pedagogical matters and consideration of some contemporary emphases in NOS-oriented curricula, including SSI-oriented teaching and efforts to shift attention towards a more authentic view of contemporary scientific practice (what Ziman (2000). Real science: What it is, and what it means. Cambridge: Cambridge University Press. calls post-academic science), the chapter concludes with a piece of personal self-indulgence: advocacy of a move towards an action-oriented, SSI-based approach to science education at the school level, and beyond.

A primary focus of the present chapter is the history and philosophy of science (HPS) and the ways that issues connected to HPS can inform genetics instruction. The chapter begins with an overview of the history of genetics which focuses on the scientific search for and the differing understandings of the gene concept. Thereafter the history of genetics is related to important philosophical issues of genetics such as reductionism, genetic determinism, and the relationship between biological function and structure. In the (...) second part of the chapter, genetic education research is reviewed, focusing on how it is informed by issues from HPS. We identify contributions of HPS-informed genetics education scholarship to the following: (1) teaching and learning genetics, (2) teaching about the nature of science, (3) humanizing science, and (4) enhancing reasoning, argumentation, and thinking skills. The primary conclusion of this review is that HPS is a much underutilized but potentially fruitful lens for approaching genetics instruction. (shrink)

Textbook descriptions of the foundations of Genetics give the impression that besides Mendel’s no other research on heredity took place during the nineteenth century. However, the publication of the Origin of Species in 1859, and the criticism that it received, placed the study of heredity at the centre of biological thought. Consequently, Herbert Spencer, Charles Darwin himself, Francis Galton, William Keith Brooks, Carl von Nägeli, August Weismann, and Hugo de Vries attempted to develop theories of heredity under an evolutionary perspective, (...) and they were all influenced by each other in various ways. Nonetheless, only Nägeli became aware of Mendel’s experimental work; it has also been questioned whether Mendel even had the intention to develop a theory of heredity. In this article, a short presentation of these theories is made, based on the original writings. The major aim of this article is to suggest that Mendel was definitely not the only one studying heredity before 1900, if he even did this, as may be inferred by textbooks. Although his work had a major impact after 1900, it had no impact during the latter half of the nineteenth century when an active community of students of heredity emerged. Thus, textbooks should not only present the work of Mendel, but also provide a wider view of the actual history and a depiction of science as a social process. (shrink)
