MATERIALS:
Before class...
– “I see...”
– “I think...”
– “I wonder...”
STUDENT ACTION | TIPS FOR SUPPORTING CRITICAL THINKING | |
STEP 1 |
Students watch the video on Step 1 of the website (1:32 minutes). |
Direct students’ attention to the following before beginning the video: Carrie is going to talk about the first task. Listen for what the task is and how to accomplish it. |
STEP 2 |
Students make qualitative and quantitative observations of the fossil record at Cleveland- Lloyd Dinosaur Quarry. Students ask questions that can be answered through scientific investigation, recording their thinking on page one of the Research Assistant Notebook (RAN). RESEARCH ASSISTANT NOTEBOOK (RAN): page 1 |
Have a brief class discussion about the limitations of the model of the quarry map. Specifically, you might ask students to explain what data they think they could get from the map, and what data they could not get. Get a baseline reading of students’ observation skills using the Student Learning Assessment Tool. Prompt students to look for patterns in the quarry map that might imply interaction among the organisms represented (such as proportion of carnivore/theropods to herbivore/sauropod/ ornithischians), or possible evidence of the effects of natural forces and phenomenon. As students complete the first task, encourage small group conversations that draw out inferences with open-ended questions such as the following:
|
REFLECT |
In pairs, students answer three reflection questions presented within the Research Quest website. |
You can view your students’ responses under the “My Account” tab when logged into the Research Quest website. Note: If students’ reflections are consistent with Carrie’s they will be prompted to move on to the next step. If they are mostly different, they will be prompted to go back and figure out how to develop more detailed observations of the quarry map. |

STEP 3 |
Students watch the video on Step 3 of the website (1:58 minutes). |
Direct students’ attention to the following before beginning the video: Carrie is going to talk about the interdependent relationships that existed in this area millions of years ago. Pay close attention to how understanding the fossil record, geology, modern animal interactions, and natural disasters can help you construct an explanation for what may have happened at Cleveland-Lloyd Dinosaur Quarry. |
STEP 4 |
In pairs, students read through and discuss background information and field notes from Cleveland-Lloyd Dinosaur Quarry. Students can keep track of useful information and analysis using pages two through four in the RAN. RAN: pages 2-4 Students next read about modern examples of mass animal death assemblages and compare and contrast what they know about Cleveland-Lloyd Dinosaur Quarry with these examples. Page five in the RAN is designed to record and analyze their ideas. RAN: page 5 |
Note: There is a large amount of information presented in this section; please adapt instructions for this section to meet the needs of your students. One possible adaptation is to assign groups different sections of the content to become “experts” on and then instruct them to share their thoughts with peers. You may also find it helpful to do the first section, “Skeletal Data,” as a class. Prompt students to think about the field notes in the context of an ancient ecosystem and reinforce the concept of stability and change by drawing on previous knowledge and experiences familiar to the students. Possible discussion points include the following:

HOW CAN EVALUATING EVIDENCE HELP US CONSTRUCT AN ARGUMENT?
(30 minutes)
STUDENT ACTION | TIPS FOR SUPPORTING CRITICAL THINKING | |
STEP 5 |
Students watch the video on Step 5 of the website (3:19 minutes). |
Direct students’ attention to the following before beginning the video: Carrie is going to discuss the three types of evidence; strong, weak, and disconfirming. Pay especially close attention to how she evaluates pieces of evidence. |
REFLECT |
In pairs, students answer three reflection questions presented within the Research Quest website. |
You can view your students’ responses under the “My Account” tab when logged into the Research Quest website. Note: If students’ reflections are consistent with Carrie’s they will be prompted to move on to the next step. If they are mostly different, they will be prompted to go back to take another look at their evidence. |
STEP 6 |
Students complete page six in the RAN, constructing explanations, analyzing their notes for evidence, and evaluating the evidence to determine which argument is the strongest. RAN: Page 6 |
Ask students to model the process of deciding whether evidence is strong, weak, or disconfirming. Clarify as needed. It may be helpful to note here that some evidence does not prove or disprove a specific explanation. While monitoring student conversations, prompt students to draw out their inferences with open-ended questions such as these:
Note: This may be a good time to introduce the Student Rubric for Presenting of Arguments to guide students as they develop their explanation and identify evidence. |

STEP 7 |
Students review the tips for communicating their arguments with their peers and prepare to present in small groups. Students may use the Student Rubric for Presenting Arguments to evaluate the strength of their argument and improve on it prior to presenting. Students may also find page seven in the RAN useful to help organize their argument. RAN: page 7 |
Tips for communicating arguments are on Step 7 of the website. Use these to facilitate conversation among groups and/or the whole class. Distribute the Student Rubric for Presenting Arguments if you haven’t already. Students can assess the strength of their group’s argument and make changes to strengthen it as needed. |
PRESENT |
Students present their argument to their peers. This includes generating, receiving, and responding to respectful critiques and clarifying questions. Students use the Student Rubric for Presenting Arguments to evaluate the strength of their peers’ arguments. Students should use this document to help identify areas of weakness in their peers’ presentations, responding with clarifying questions and respectful critiques. |
There are many forms that student presentations could take. Choose a method that you prefer. Ask open-ended questions that draw out inferences. Some students may benefit from using sentence stems to help facilitate discussion about their ideas. Evaluate students on the critical thinking skills you are targeting in this section using the Student Learning Assessment Tool as a guide. Encourage students to actively listen and respond to each others’ presentations. Note: Many students may at first be uncomfortable constructing and responding to helpful critiques and questions. Emphasize that engaging in argument from evidence in science is not about having the “correct” answer, it is about identifying relevant evidence, evaluating that evidence, and then communicating your thinking to others. |
STEP 8 |
In pairs, students fill out the web form on Step 8 of the website and press “submit” to share their group’s argument with Carrie. |
Note: This step is optional. However, if students do submit this form you will be able to access their responses in your admin dashboard on the Research Quest website. |
STEP 9 |
In pairs or small groups, students watch the videos on Step 9 of the website, using the Student Rubric for Presenting Arguments to evaluate the strength of each explanation. In groups or as a class, students engage in a brief discussion about which of the arguments that Carrie presented is the strongest. |
Direct students’ attention to the following before beginning the videos: Carrie is going to present the leading arguments for what happened at Cleveland-Lloyd Dinosaur Quarry. As you watch each video, evaluate the strength of each explanation and associated evidence. Use the Student Rubric for Presenting Arguments to determine which argument seems to be the strongest. |
STEP 10 |
Students may complete additional extension activities. |
Optional extension activities are provided on the website to take student learning a step further. The Student Rubric for Assessing Learning Outcomes is located in the support materials for each investigation. Using this rubric, students can reflect on the critical thinking skills they developed and practiced during this investigation, and think about ways they can continue to use these skills in the future. Reinforce critical thinking skills, vocabulary, and other target behavior during curriculum-aligned activities. |
