Development of Scientific Thinking

Promoting Development of Scientific Thinking

Some people think of science as learning facts about the world around us. Others think of science and other ways of knowing as “the having of wonderful ideas” (Duckworth, 1987). This latter view of science and ways of knowing match the characteristics of young children as learners. Young children are naturally curious and passionate about learning (Raffini, 1993). In their pursuit of knowledge, they’re prone to poking, pulling, tasting, pounding, shaking, and experimenting. “From birth, children want to learn and they naturally seek out problems to solve” (Lind, 1999, p. 79). Such attitudes and actions on the part of young children indicate that they engage in scientific thinking and actions long before they enter a classroom (Zeece, 1999). Unfortunately, when science education is introduced in a formal setting, it often reflects the understanding of science as the learning of facts. This approach has led some educators to suggest that “most science learning that takes place in formal settings is not true science” (Zeece, 1999, p. 161).This article will discuss the benefits of active, hands-on learning, goals for early childhood science programs, and suggestions for fostering scientific learning in the early childhood classroom. Science as Active Exploration While it is appropriate to introduce older students to science history and expect them to learn facts discovered by others, young children should learn science (and all other areas of study) through active involvement – that is, through first-hand, investigative experiences. Young children should be involved in “sciencing” versus the learning of scientific facts presented by others (Kilmer & Hofman, 1995; Mayesky, 1998; Zeece, 1999). Sciencing is a verb and suggests active involvement. Such involvement should be both hands-on and minds-on in nature. Thus, children should be engaged both physically and mentally in investigating and manipulating elements in their environment (Chaille & Britain, 2003; Kilmer & Hofman, 1995). To be developmentally appropriate and to be in compliance with national guidelines for the teaching of science, science education at the preschool and primary level must be “an active enterprise” (Lind, 1999, p. 73). Both the National Science Education Standards (National Research Council, 1996) and Benchmarks for Science Literacy (American Association for the Advancement of Science, 1993) call for an action-oriented and inquiry-based approach to science with young children. As articulated by Lind (1999), “the best way to learn science is to do science” (p. 74). Therefore, science for young children should involve asking questions, probing for answers, conducting investigations, and collecting data. Science, rather than being viewed as the memorization of facts, becomes a way of thinking and trying to understand the world. This approach allows children to become engaged in the investigative nature of science (Kilmer & Hofman, 1995; Lind, 1999) and to experience the joy of having wonderful ideas (Duckworth, 1987). Discovery Learning Teachers can’t give children “wonderful ideas”; children need to discover or construct their own ideas. Developing new concepts or ideas is an active process and usually begins with child-centered inquiry, which focuses on the asking of questions relevant to the child. While inquiry involves a number of science-related activities and skills, “the focus is on the active search for knowledge or understanding to satisfy students’ curiosity” (Lind, 1999, p. 79). Knowing the right answer, then, is not one of the primary objectives of science in the early childhood curriculum. Duckworth (1987) refers to “knowing the right answer” as a passive virtue and discusses some of its limitations. “Knowing the right answer,” she says, “requires no decisions, carries no risks, and makes no demands. It is automatic. It is thoughtless” (p. 64). A far more important objective is to help children realize that answers about the world can be discovered through their own investigations. Sciencing, for example, involves coming up with ideas of one’s own. Developing these ideas and submitting them to someone else’s scrutiny is, according to Duckworth (1987), “a virtue in itself—unrelated to the rightness of the idea” (p. 68). Developing ideas of one’s own add breadth and depth to learning. This is so, even if the child’s initial ideas are inaccurate views of the world. Duckworth (1987) explains: “Any wrong idea that is corrected provides far more depth than if one never had a wrong idea to begin with. You master the idea much more thoroughly if you have considered alternatives, tried to work it out in areas where it didn’t work, and figured out why it was that it didn’t work, all of which takes time” (pp. 71-72). Science Goals Desired goals of science in the early childhood curriculum include what we hope children will attain or achieve in three different areas: content, processes, and attitudes or dispositions. Content refers to the body of knowledge representing what we know about the world. Children’s body of knowledge develops and increases over time, and their desire to communicate and represent their knowledge should be acknowledged and supported. The processes, or process skills, represent the active component of science and include such activities as predicting, observing, classifying, hypothesizing, experimenting, and communicating. Adults should support children in practicing and applying these skills in a variety of activities throughout the day. This can be done by showing a sincere interest in children’s observations and predictions and by providing a variety of materials and settings that invite experimentation. Certain attitudes or dispositions are also central to scientific inquiry and discovery. These include curiosity, a drive to experiment, and a desire to challenge theories and to share new ideas (Conezio & French, 2002). Teachers should value these attitudes or dispositions, be aware of how they are manifested in young children, and find ways to acknowledge and nurture their presence. sumber : By Ruth Wilson, Ph.D.
