Assessment Overview
Week A: Teacher as Problem Solver—Individual
Private Theory Assignment & Rubric

Weeks 4, 7, 10, 13

Assignment  Rubric

Goal: Identify what you believe to be true (private theories) and the reasons for why you have those beliefs.

Background: The mind is a wonderful thing. As soon as you read or hear a question, your mind races to make associations, bring prior experiences to bear, and generate hypotheses. It is said that "nature abhors a vacuum" and the mind may be no different.

Piaget demonstrated that even five year olds have theories about almost everything. When he asked Swiss five-year-olds, "Which came first--Lake Geneva or the city of Geneva?" they each had a theory and reasons for their thinking. "The city came first, then they built the lake to swim in," some said. Or, "They liked the lake so they built a city around it."

Unless private theories are revealed and examined, they often remain intact, in spite of countervailing evidence. Students learn quickly that "explanation giving" not "theory building" is required in most classes to be successful. Students tell teachers what others--the book, the experts, the teacher--think, not what they think.

What keeps people from revealing their theories? Often, no one asks about them. Or, when a theory is revealed, it is critiqued, rather than explored. People do not want to be wrong. Another reason is that people may not even be used to examining their own thoughts and beliefs. Private theories are tenacious, so evolving them takes time, discussion, and experience, which are often not the emphasis of the standard curriculum or way of teaching.

To get your private theories out and well-elaborated, state what you think. Make that educated guess, search for what "makes sense" to you, and pull out the reasons for why you think so. By starting with your private theories, you will be more actively engaged in supporting, elaborating, or debunking them. The purpose of this assignment is for you to list what you already know. You do not need to conduct any research to do this assignment.

Use the directions below to complete your private theory assignment.

Assignment (by midnight Wednesday)

Posting Instructions for steps 1-2
Go to the Classroom. Click on the event name (Volcanoes, Coral Reefs, Tropical Forests, Ozone, Global Change) you are studying in this particular cycle to enter the appropriate event classroom. Then click on the Teacher as Problem Solver graphic.

1. Post your list of hypotheses, ideas, or hunches about the event described in the scenario (PBL Step 2).

2. List what you know about the event (PBL Step 3) and the reasons for how you know. Write your information in the form of an ESS analysis. If needed, refer to the Week 2: The Integration of the ESS Analysis and the PBL Model reading and the diagram below to get you thinking about the various interactions and interrelationships that occur between and among the spheres and event. Don't be concerned if this particular ESS topic is not one of your strengths; you are here to learn, and the Earth system science analysis is only the starting point. The purpose of this assignment is for you to list what you already know. You do not need to conduct any research to do this assignment.
Posting Instructions for step 3
Go to the Classroom to select the appropriate event classroom, then click on the Teacher As Problem Solver graphic.

3. Read your teammates' postings and respond to at least one teammate's posting. Remember to be curious rather than judgmental about your teammates' ideas.

 


Rubric
Your individual Week A: Teacher as Problem Solver assignment corresponds to PBL Steps 1, 2, and 3 and focuses on an Earth system science event. The rubric below assesses how well you do PBL Steps 2 and 3 in your effort to get your private theories out and well-elaborated.

Using the same rubric that your facilitator will use, you can rate your attempt to express your private theories. Remember you are developing your ability and willingness to make your thinking visible, so you can grow your theories in sophistication and accuracy.

You can earn as many as five points for completing this assignment. You will automatically earn one point for submitting your assignment on time. See the Time Rubric. Use the criteria and indicators below to gauge your success in earning the remaining four points.

Rubric Criteria: What you really believe to be true, "I think..."
4 Rating:
A clear and focused hypothesis of your beliefs about the relationship
s in Earth systems.
3 Rating
A hypothesis summarizing what you believe to be true about ESS relationships.
2 Rating
A clear statement of what you believe to be true about some of the relationships.
1 Rating: A description of some things you know.
Rubric Criteria: Supported by reasons, "Because..."
4 Rating:
Your thinking is visible with clear ESS explanations or assertions in support of your hypothesis.
3 Rating: Your hypothesis is supported with some ESS explanations or assertions. 2 Rating: Some reasoning behind what you believed is revealed. 1 Rating: Some reasons given for how you know what you think you know.
Rubric Criteria: Uses what you currently know, "These reasons come from..."
4 Rating:
Relevant knowledge and reasons from multiple sources and examples from your experience.
3 Rating: Relevant knowledge and reasons from a few sources and/or relationship to experience. 2 Rating: Relevant knowledge is supported by at least one reason or some relationship to experience. 1 Rating: Some related experiences and references or schooling is given.
