Evidence-based Decision-making

Evidence-based Decision-making

TEKS Objective

The student is expected to in all fields of science, analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, including examining all sides of scientific evidence of those scientific explanations, so as to encourage critical thinking by the student.

Essential Understanding

The student uses critical thinking and scientific problem solving to make informed decisions.

Science Background

Evidence-Based Decision-Making: Serve Center (website) - Ideas and strategies to help educators incorporate evidence-based decision-making into their own teaching and improve student motivation and achievement.

Signature Lesson

Introduction to Experimental Design: Learn NC (website) - Students learn and use experimental design vocabulary and develop critical thinking skills by reading an experiment description, analyzing the information provided, and applying empirical evidence and logic to answer questions about the experiment design and outcomes.

Elaboration Lessons and Extensions

Bias Sampling: Science NetLinks (website) - Students learn that data gathered during a scientific study can be biased or unusable if the methodology is flawed. Includes assessment and extensions.

Assessment Ideas

Have student groups design and conducts tests to compare two or three brands of the same commercial product. Then have each student write a paper that uses evidence collected during the test to identify the best product among those considered.
