Show Me The Evidence

Science stories in the news – especially stories about dinosaurs - are a terrific opportunity to help students practice critical questioning skills. Often press and news stories focus on how the discovery is the “biggest,” “baddest,” “fastest,” “meanest,” etc. These attributes may be exaggerated; they may not even be based on scientific evidence. Students can learn to ask critical questions about the stories they read in the paper or online by beginning with a basic question: “What is X based on?” (Show me the evidence!) Getting past the “biggest” and the “baddest” to the science in the story (or the lack of it) will take some practice.

Sample Questions to Pose to Media Stories about Dinosaurs and Other Discoveries

What was actually found?

  • Isolated bones? A partial disarticulated skeleton? One individual? Evidence of more than one individual? A bone bed? Sometimes a story about a big discovery doesn’t even identify what the discovery consisted of!

What is the interpretation based on?

  • What evidence is the scientist basing their interpretation on? Is it related to what they found specifically? Is it related to analogies in the living animal world? What evidence are they using to connect the living and fossil world?

Is the article about a discovery? Fieldwork? An announcement or publication in a scientific journal?

  • There are big differences between a publication in a scientific journal and a press story. Publication in a scientific journal usually requires a peer review process prior to publication. Announcing a discovery without publication in a scientific journal may mean that there has not been a chance for other scientists to review the findings, ask important questions, or critique the interpretations.

Critical Thinking Is A Skill That Can Be Developed With Practice. Here Are Some Ways To Help Students Learn – And Practice – Questioning Skills:

  • Give students TIME to observe and practice observation with note taking.
  • Encourage students to describe what they see with as many specific details as possible. Being able to give a detailed description should become a habit. Encourage students to “be as specific as they can", use the “best words” they can, make comparisons to thingswith witch they are familiar, come up with an analogy. Encourage the students who are listening to someone offering a description to ask for more information – and to learn to specifically compliment “effective descriptions” - that is, compliment descriptions that help others see and observe what the student notices
  • Ask students to literally “show you” where their idea (or the detail they’re bringing attention to) came from - have them point to it, draw it, underline the specific words in the text. Ask, “What is that idea based on?” “Where is your evidence for that idea, specifically?”
  • Be attentive to your own questions: broad questions let students explore and choose for themselves; specific questions will cue them to understand there is something particular you want them to focus on. Decide beforehand what your goals are when you are asking questions
  • Help students to see that whatever they are studying fits into a larger context; encourage them to ask questions about how things are connected; practice brainstorming connections between things that might not seem connected at all.

Need An Article To Get Started? Try This One:

“Dinosaurs Hunted in Packs” http://news.bbc.co.uk/1/hi/sci/tech/1036004.stm
Begin by asking students to circle all the adjectives. What do they notice about the words they circled? Are these descriptive words actually referring to something scientific? What evidence has actually been found in this piece?
