Purpose of Science Education?
• 1990’s, both AAAS and the NRC develop science education standards that included components of the nature and process of science (AAAS, 1993; NRC, 1996). • Yet, “Rather than learning how to think scientifically, students are generally being told about science and asked to remember facts.”
The Process of ScienceSelected Key Concepts
• Science is a process of investigation into the natural world and the knowledge generated through that process.
• Scientific theories are testable explanations supported by multiple lines of evidence.
• Scientific knowledge evolves with new evidence and perspectives.• Science benefits from the creativity, curiosity, diversity, and diligence
of individuals. • The community of science engages in debate and mitigates human
errors.• Uncertainty is inherent in nature, but scientists work to minimize and
quantify it in data collection and analysis.• Scientists value open and honest communication in reporting
research.
The Process of ScienceModules Developed
Science• The Nature of Scientific Knowledge*• Theories, Hypotheses, & Laws†
• Scientists & the Scientific Community• Scientific Institutions• Scientific Controversy*• Scientific Ethics
Scientific Communication• Journals & Articles• The Literature• Peer Review
Research Methods• Comparison• Description• Experimentation• Modeling
Data• Analysis & Interpretation• Uncertainty, Error & Confidence• Statistics• Using Graphs & Visual Data
†In press, *In development
Process of Science in NSC107
•Incorporation of 10 “Process” modules:• 5 Research Methods modules;• 4 Data & Analysis modules;• Understanding Scientific Journals.
• Integration of data and research into the curriculum instead of simply outcomes
Pre-Assessment
Main point of science?• Use of experimentation to solve or understand scientific equations.• Scientific method is the basis of all scientific experimentation.• How to make an experiment.• Experimenting.• How to experiment with research.
Post-Assessment
Main point of science?
• One of the main things I will take away is that I know the functions of science. Perhaps that[s] all, but before I felt that I did not know much, but now I know how and why certain things happen. Overall, in order to know things, not just in science, research is necessary, time, interest, dedication and ultimately a group and foundation of people working together.
• The main thing I will take away is a different perspective on things. Science was always taught only one way, and that was it. There was no variation or anything. This class allowed me to see science in another light.
