For example, explaining why the temperature of water does not increase beyond 100°C when heated requires students to envisage water as consisting of microscopic particles and that the energy provided by heating can allow fast-moving particles to escape despite the force of attraction holding the particles together. ), Teaching Scientific Inquiry: Recommendations for Research and Implementation (pp. Being literate in science and engineering requires the ability to read and understand their literatures [34]. A realistic look at the role of technology in education. From its inception, one of the principal goals of science education has been to cultivate students’ scientific habits of mind, develop their capability to engage in scientific inquiry, and teach them how to reason in a scientific context [1, 2]. Being a critical consumer of science and the products of engineering, whether as a lay citizen or a practicing scientist or an engineer, also requires the ability to read or view reports about science in the press or on the Internet and to recognize the salient science, identify sources of error and methodological flaws, and distinguish observations from inferences, arguments from explanations, and claims from evidence.

This optimization process typically involves trade-offs between competing goals, with the consequence that there is never just one “correct” solution to a design challenge. Students should be helped to recognize that they may need to explore more than one way to display their data in order to identify and present significant features. Such ambiguity results in widely divergent pedagogic objectives [18]—an outcome that is counterproductive to the goal of common standards. Scientists do use deductive reasoning, but they also search for patterns, classify different objects, make generalizations from repeated observations, and engage in a process of making inferences as to what might be the best explanation. Students need opportunities to design investigations so that they can learn the importance of such decisions as what to measure, what to keep constant, and how to select or construct data collection instruments that are appropriate to the needs of an inquiry. And Christina and Marcus are getting their first jobs as architects, starting the same place Gloria did 20 years ago, designing a playground. The move from a static model in an inert medium, like a drawing, to dynamic models in interactive media that provide visualization and analytic tools is profoundly changing the nature of inquiry in mathematics and science. Historical case studies of the origin and development of a scientific idea show how a new idea is often difficult to accept and has to be argued for—archetypal examples are the Copernican idea that Earth travels around the sun and Darwin’s ideas about the origin of species. For example, student teachers can replay videos of classroom events to learn to read subtle classroom clues and see important features that escaped them on first viewing. As applications have spilled over from other sectors of society, computer-based learning tools have become more sophisticated (Atkinson, 1968; Suppes and Morningstar, 1968). The public imagination. Chicago: University of Illinois Press. Teachers can log into TAPPED IN to discuss issues, create and share resources, hold workshops, engage in mentoring, and conduct collaborative inquiries with the help of virtual versions of such familiar tools as books, whiteboards, file cabinets, notepads, and bulletin boards. have opportunities to plan and carry out full engineering design projects in which they define problems in terms of criteria and constraints, research the problem to deepen their relevant knowledge, generate and test possible solutions, and refine their solutions through redesign. With these tools, scientists can discern patterns more quickly and detect relationships not previously noticed (e.g., Brodie et al., 1992; Kaufmann and Smarr, 1993). In engineering, the goal of argumentation is to evaluate prospective designs and then produce the most effective design for meeting the specifications and constraints. In R. Sternberg and D. Preiss (Eds. The Belvedere system, for example, is designed to teach science-related public policy issues to high school students who lack deep knowledge of many science domains, have difficulty zeroing in on the key issues in a complex scientific debate, and have trouble recognizing abstract relationships that are implicit in scientific theories and arguments (Suthers et al., 1995). CSILE also includes guidelines for formulating and testing conjectures and prototheories. F rom its inception, one of the principal goals of science education has been to cultivate students’ scientific habits of mind, develop their capability to engage in scientific inquiry, and teach them how to reason in a scientific context [1, 2].There has always been a tension, however, between the emphasis that … London, England: Hodder Arnold. Often both teachers and students are novices, and the creation of knowledge is a genuinely cooperative endeavor. Modern theoretical physics is so heavily imbued with mathematics that it would make no sense to try to divide it into mathematical and nonmathematical parts. Some of the models used by scientists are mathematical; for example, the ideal gas law is an equation derived from the model of a gas as a set of point masses engaged in perfectly elastic collisions with each other and the walls of the container—which is a simplified model based on the atomic theory of matter. London, England: Allen & Unwin. CSILE has been used in elementary, secondary, and postgraduate classrooms for science, history, and social studies. The students were compared with non-Jasper comparison classes on standardized test scores of mathematics, problems requiring complex problem solving, and attitudes toward mathematics and complex challenges. In other words, science is not a miscellany of facts but a coherent body of knowledge that has been hard won and that serves as a powerful tool. Scaffolded experiences can be structured in different ways. In the first, careful observation and description often lead to identification of features that need to be explained or questions that need to be explored. Procedural knowledge has also been called “concepts of evidence” [47]. (2009). Seeing science as a set of practices shows that theory development, reasoning, and testing are components of a larger ensemble of activities that includes networks of participants and institutions [10, 11], specialized ways of talking and writing [12], the development of models to represent systems or phenomena [13-15], the making of predictive inferences, construction of appropriate instrumentation, and testing of hypotheses by experiment or observation [16]. 1. In reality, practicing scientists employ a broad spectrum of methods, and although science involves many areas of uncertainty as knowledge is developed, there are now many aspects of scientific knowledge that are so well established as to be unquestioned foundations of the culture and its technologies. In many of these student-scientist partnerships, students collect data that are used to understand global issues; a growing number of them involve students from geographically dispersed schools who interact through the Internet. •     Identify gaps or weaknesses in explanatory accounts (their own or those of others). •     Plan experimental or field-research procedures, identifying relevant independent and dependent variables and, when appropriate, the need for controls.

(2004). Asking questions (for science) and defining problems (for engineering), 3. Through a randomized control trial of students in a for-credit online course at a public 4-year university, we test the efficacy of a scheduling intervention aimed at improving students' time management.
