What does it mean to think scientifically? We might label a preschooler’s curious question, a high school student’s answer on a physics exam, and scientists’ progress in mapping the human genome as instances of scientific thinking. But if we are to classify such disparate phenomena under a single heading, it is essential that we specify what it is that they have in common. Alternatively, we might define scientific thinking narrowly, as a specific reasoning strategy (such as the control of variables strategy that has dominated research on the development of scientific thinking), or as the thinking characteristic of a narrow population (scientific thinking is what scientists do). But to do so is to seriously limit the interest and significance the phenomenon holds. This chapter begins, then, with an attempt to define scientific thinking in an inclusive way that encompasses not only the preceding examples, but numerous other instances of thinking, including many not typically associated with science. WHAT IS SCIENTIFIC THINKING? Scientific thinking as knowledge seeking Is scientific thinking of any relevance outside of science? In this chapter I answer this question with an emphatic yes and portray scientific thinking as a human activity engaged in by most people, rather than a rarefied few. As such, it connects to other forms of thinking studied by cognitive psychologists, such as inference and problem-solving. In particular, I highlight its connection to argumentive thinking (Kuhn, 1991) and characterize its goals and purposes as more closely aligned with argument than with experimentation (Kuhn, 1993; Lehrer, Schauble, & Petrosino, 2001). Scientific thinking is most often social in nature, rather than a phenomenon that occurs only inside people’s head. A group of people may rely jointly on scientific thinking in pursuing their goals. To fully appreciate scientific thinking, it must be situated in a developmental framework, with a goal of identifying both its origins and endpoints. These endpoints are more general than the practices and standards of professional science. The most skilled, highly developed thinking that we identify here is essential to science, but not specific to it. The definition of scientific thinking adopted in this chapter is knowledge seeking. This definition encompasses any instance of purposeful thinking that has the objective of enhancing the seeker’s knowledge. One consequence that follows from this definition is that scientific thinking is something people do, not something they have. The latter we will refer to as scientific understanding. When conditions are favorable, the process of scientific thinking may lead to scientific understanding as its product. Indeed, it is the desire for scientific understanding -- for explanation -- that drives the process of scientific thinking. Scientific thinking and scientific understanding The distinction between scientific thinking and scientific understanding is an important one, since there has arisen in recent years an extensive literature on children’s developing understandings in the domains of physics, biology, and psychology (see Gelman & Kalish, 2006, for review). From their earliest years, children construct implicit theories that enable them to make sense of and organize their experience. These early theories are most often incorrect, as well as incomplete. In a process that has come to be referred to as conceptual change, these theories are revised as new evidence is encountered bearing on them. Knowledge acquisition, then, is not the accumulation of isolated bits of knowledge, but, rather, this process of conceptual change. In contrast...
