2025 Philadephia Institute:

Teaching Students to Evaluate Sources and Claims


Day 1

Logistics

Introductions & Icebreaker


Science in the News

How often do you see claims made in the news that seem to be backed by scientific evidence? How can you tell what is real and what is not? Analyze two sources to identify claims or models and the evidence that supports them.


Break

Take a break and take a little time for yourself.



Disciplinary Venn Diagram

Consider how Science, Social Studies, and Language Arts practices overlap in each content area.

LR Activity: Conserving Attention with Lateral Reading

While students are able to quickly access vast amounts of information today, they often need help deciding what deserves their attention.


LR Activity: Introduction to Credibility

What does it mean for a source to be credible? How do you decide whether to believe someone?


Break

Take a break and take a little time for yourself.



MEL Activity: Wetlands pcMEL

Use a pre-constructed MEL (pcMEL) diagram to investigate two explanations about how wetlands affect humans and the environment.


Connections between LR and MEL Activities

Revisit your Disciplinary Venn Diagram posters. What connections exist between an LR lesson and a MEL lesson? What further connections can we make?


Wrap Up

Feedback on two questions: 1) How do you feel after today? and 2) What questions do you have after today?

Feedback on two questions: 1) How do you feel after today? and 2) What questions do you have after today?

  • 1) How do you feel after today?


  • 2) What questions do you have after today?



Day 2

LR Activity: Introducing Lateral Reading

What does it mean for a source to be credible? Why should we investigate whether a source is credible before we read it?


Break

Take a break and take a little time for yourself.



MEL Activity: Soil and Food Security baMEL

Build a MEL (baMEL) diagram to investigate the role of soil in providing food for the world's growing global population. Choose from three models and eight lines of evidence.


MEL Activity: Compare and Contrast pcMELs and baMELs

What are the instructional differences for students and teachers between pcMELs and baMELs?


LR Activity: Modeling Lateral Reading


Lunch

Lunch!


Talk Moves

In order to process, make sense of, and learn from their ideas, observations, and experiences, students must talk about them. What does academically productive talk look like?


MEL Activity: Introducing the Energy baMEL


Break

Take a break and take a little time for yourself.



MEL Activity: Assessing Student Work


LR Activity: Discussions about Lateral Reading


Wrap Up

Feedback on two questions: 1) How do you feel after today? and 2) What questions do you have after today?

  • 1) How do you feel after today?


  • 2) What questions do you have after today?



Day 3

MEL Research Talk

How do students negotiate evaluations of the relations between lines of scientific evidence and alternative explanatory models of a phenomenon during an argument-based learning activity? How do students plausibility judgements change pre- and post- MEL activities? Does this make a difference between pcMELs and baMELs? What does the research show?


LR Activity: Addressing Unhelpful Strategies

What do you think/know your students have learned from other classes or past teachers about evaluating online information? How can you help counter unhelpful strategies?


Break

Take a break and take a little time for yourself.



MEL Activity: Discourse Strategies

Negotiation is a subset of argumentation, where students present a position and agree or disagree with each other by offering explanations and counter arguments. How can we help students engage in constructive discourse during argumentation? What strategies help scaffold student discourse so that negotiation leads to consensus?


LR Activity: After Lateral Reading

Explore additional resources, ways to assess lateral reading, and strategies, such as click restraint, that might help students abandon sources that aren't credible enough for their information goals. How do we respond to students' experiences, knowledge, and beliefs?


Lunch

Lunch!


LR Skills in Science Classrooms

How does LR integrate with MELs? What resources do we provide? How do you use LR beyond the MELs?


MEL Skills in ELA/SS Classrooms

What constitutes evidence in your subject (ELA and/or social studies)? How does your subject evaluate the quality of claims? How does your subject compare the truthfulness of alternative claims/explanations?


The LR and MEL Teacher Guides

How can you use MEL and LR activities in the classroom? The Teacher Guides provide directions and tips.


LR-MEL Website & Other Resources

The LR-MEL Website contains teaching materials and professional development resources. Take a quick tour of what's there.

  • Website Resources (Acrobat (PDF) 578kB Jan28 26)
  • The LR-MEL project website
  • With this grant we have added lateral reading activities along with pcMEL and baMEL activities to the website.
  • Materials from this workshop and more are posted here.


Implementation Planning

If you're here in a team, what will implementing LR and MEL in your classrooms look like? What kinds of coordination will you need to do? If you're flying solo, what components (LR or MEL) can you use? Are there ways to bring in the principles of the other into your classroom? Are there teammates at your school that you could teach with about LR and MEL?




Day 4

Science in the News part 2

How do students apply claims-based reasoning beyond the classroom? How do we support students' evidence-based reasoning with new science concepts & articles? Analyze two sources to identify claims or models and the evidence that supports them.


Making LR and MEL Connections

How might LR and MEL activities go together? What could this look like in the classroom?


Implementation Planning Continued

If you're here in a team, what will implementing LR and MEL in your classrooms look like? What kinds of coordination will you need to do? If you're flying solo, what components (LR or MEL) can you use? Are there ways to bring in the principles of the other into your classroom? Are there teammates at your school that you could teach with about LR and MEL?
