“Teaching Science as Inquiry” • Teaching -To impart knowledge or skill • -To provide knowledge of… • -To advocate for… • Science -Content and processes • As -To the same extent or degree, equally • -The consequent in correlative construction • Inquiry -A question • -To request information • -To investigate
In.quir.y (In´ kwir´ ē) n., pl.ies. 1. An outcome of science teaching that is characterized by knowledge and understanding of the processes and methods of science. 2. Outcomes of science teaching that refer to specific skills and abilities integral to the processes and methods of science. 3. The instructional strategies used to achieve students’ knowledge and understanding of science concepts, principles, and facts and/or the outcomes described in the aforementioned definitions 1 and 2.

Science As Inquiry in ESCP Earth Science • In this investigative approach, science is presented as inquiry, as a search for new and more accurate knowledge about the earth. The student learns through experiences in the laboratory by using scientific methods that have led to our present knowledge of science, as well as to a feeling of the incompleteness and uncertainty of this knowledge. • (Teachers Guide for ESCP, 1967, p. 3)

BSCS 5E INSTRUCTIONAL MODEL Engage The instructor assesses the learners’ prior knowledge and helps them become engaged in a new concept by reading a vignette, posing questions, presenting a discrepant event, showing a video clip, or conducting some other short activity that promotes curiosity and elicits prior knowledge (Champagne, 1987). Explore Learners work in collaborative teams to complete lab activities that help them use prior knowledge to generate ideas, explore questions and possibilities, and design and conduct a preliminary inquiry (Renner, Abraham, & Bernie, 1988). Explain To explain their understanding of the concept, learners may make presentations, share ideas with one another, review current scientific explanations and compare these to their own understanding, or listen to an explanation from the teacher that guides the learners toward a more in-depth understanding (Renner, Abraham, & Bernie, 1988). Elaborate Learners elaborate their understanding of the concept by conducting additional lab activities. They may revisit an earlier lab and build on it or conduct an activity that requires an application of the concept (Renner, Abraham, & Bernie, 1988). Evaluate The evaluation phase helps both learners and instructors assess how well the learners understand the concepts and whether or not they have met the learning outcomes (Kulm & Malcom, 1991).

National Science Education Standards Scientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work. Inquiry also refers to the activities of students in which they develop knowledge and understanding of scientific ideas as well as an understanding of how scientists study the natural world. (NRC, 1996, p. 28)
Abilities of Scientific Inquiry • Identify questions and concepts that guide scientific investigations • Design and conduct scientific investigations • Use technology and mathematics to improve investigations and communications • Formulate and revise scientific explanations and models using logic and evidence • Recognize and analyze alternative explanations and models • Communicate and defend a scientific argument) • (NRC, 1996)
Understandings about Scientific Literacy • Scientists usually inquire about how physical, living, or designed systems function. • Conceptual principles and knowledge guide scientific inquiries. • Scientists conduct investigations for a wide variety of reasons. • Scientists rely on technology to enhance the gathering and manipulation of data. • Mathematics is essential in scientific inquiry. • Scientific explanations must adhere to criteria such as: a proposed explanation must be logically consistent; it must abide by the rules of evidence; it must be open to questions and possible modification; and it must be based on historical and current scientific knowledge. • Results of scientific inquiry—new knowledge and methods—emerge from different types of investigations and public communication among scientists. In communicating and defending the results of scientific inquiry, arguments must be logical and demonstrate connections between natural phenomena, investigations, and the historical body of scientific knowledge. In addition, the methods and procedures that scientists used to obtain evidence must be clearly reported to enhance opportunities for further investigation. • (NRC, 1996)

PISA 2006: Definition of Scientific Literacy • PISA defines scientific literacy in terms of an individual’s: • Scientific knowledge and use of that knowledge to identify questions, to acquire new knowledge, to explain scientific phenomena, and to draw evidence-based conclusions about science-related issues • Understanding of the characteristic features of science as a form of human knowledge and inquiry • Awareness of how science and technology shape our material, intellectual, and cultural environments • Willingness to engage with science-related issues, and with the ideas of science, as a reflective citizen
PISA 2006: Attitudes Toward Scientific Inquiry • Support for scientific inquiry • Acknowledge the importance of considering different scientific perspectives and arguments • Support the use of factual information and rational explanations • Express the need for logical and careful processes in drawing conclusions • Demonstrate awareness of the environmental consequences of individual actions
The PISA Science Framework Context Life situations that involve science and technology… Requires you to Competencies • Identify scientific Issues • Explain phenomena scientifically • Use scientific evidence How you do so is influenced by Knowledge a) What you know: • About the natural world (knowledge of science) • About science itself (knowledge about science) Attitudes b) How you respond to science issues (interest, support for scientific inquiry, responsibility)
