2024 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.


Lunch

Lunch!


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?














Day 2

LR Activity: Extreme Weather

Use lateral reading to evaluate the credibility of two sources related to extreme weather.


Break

Take a break and take a little time for yourself.



MEL Activity: Soil & 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: Applying MEL Skills in ELA/SS Classrooms

Consider evidence, explanations, claims and thruthfulness in relation to your subject area.


Lunch

Lunch!


MEL Activity: Assessing Student Work

Read an article. Then use a rubric to assess NGSS scientific practices and cross-cutting concepts within samples of student MEL explanation tasks.


LR Activity: Modeling Lateral Reading

Plan a modeling lesson for lateral reading. Analyze a transcript of Sarah modeling. Then generate your own script for modeling lateral reading. "Model" that script and reflect on the process with a partner.


Break

Take a break and take a little time for yourself.



MEL Activity: Dead Zones baMEL

A dead zone is an area of water that is low in oxygen. Aquatic life cannot survive in a dead zone. Build a MEL (baMEL) diagram to investigate whether and how aquatic dead zones may be repaired. Choose from three models and eight lines of evidence.


LR Activity: Facilitating Discussions About Lateral Reading

What purpose does discussion serve in a lateral reading lesson? Plan a discussion about a source, rehearse that discussion with your colleagues, and reflect on the process with them.


Wrap Up

Feedback on two questions: 1) What are two takeaways from today's sessions? and 2) What is one thing you are considering using in your classroom?


























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.



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?


Lunch

Lunch!


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. 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?


MEL Activity: The MEL Project Teacher Guide

Take a tour of The MEL Project Teacher Guide. Check out directions and hints for using pcMELs, baMELs, and virtual MELs in the classroom.


Break

Take a break and take a little time for yourself.



The Transfer Task

Use a transfer task to determine if students can: 1) transfer the skills acquired from Lateral Reading, MELs, and baMELs to science phenomenon and claims made in real-world scenarios; 2) identify models and evidence in science articles; and 3) based on the evidence presented, evaluate the plausibility of each model. What do students do differently when evaluating articles compared to the MEL task? What similarities?


Wrap Up

Feedback on two questions: 1) How comfortable are you using lateral reading and MELs? and 2) What outstanding questions do you have at this time?






















Day 4

Online Materials

Take a quick tour of the project website.

  • Website Resources (Acrobat (PDF) 534kB Jun28 24)
  • 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.


Making LR and MEL Connections

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


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?


Wrap Up
