Why use concept maps?
Externalize learner’s knowledge: Structural Knowledge (types & number of links) Can see how students integrate & represent information Conceptual Knowledge (via links and concepts) Makes misconceptions explicit (wrong links). Allows for finely targeted remediation. Declarative Knowledge Makes knowledge gaps explicit (missing nodes or links). Helps students develop meta-knowledge. Facilitates encoding, recall, and higher level reasoning.

What do you do when your class performs poorly on a test?
Adjust the scores upward. Grade on a curve. Adjust the difficulty of the next assessment. Give advice on study strategies. Long for the “good old days” Provide more practice problems, review. Spend more time on the material in the future. Change your teaching materials or approach.

How do you know what to change in your instruction?
• Integrating assessment into the instructionlearning cycle can help us determine: • • • • If learning failures have occurred Why learning failures have occurred, What an effective course of action might be Whether our action has been effective.

What does assessment have to do with learning?
Good assessments provide opportunities for students to both learn and reveal their learning. All learning requires feedback but the feedback must be informative. - Feedback must provide guidance to the student and the instructor on what to do to improve performance. Learners must learn how to use feedback to improve performance Grades or scores help professors and students monitor learning, but they do little to promote learning

Observation
Interpretation
Cognition
What skills and knowledge are required and valued in my domain? How do the knowledge and skills develop? What is the trajectory from novice to expert? Are there popular misconceptions students possess? Are there consistent points of difficulty Are there prerequisites that students may not have How are these domain skills combined with general skills? Problem solving skills (planning, decomposition, result checking, etc) when faced with a complex project or assignment.

All good assessment connects these 3 components
Observations Interpretation
Every assessment:
Cognition
•Is based in a “theory” of how people learn, what they know and how knowledge and skill progresses over time
•Embodies assumptions about which tasks are most likely to elicit demonstrations of what students know and can do.
•Is based on assumptions about how best to interpret the outcomes to draw meaningful inferences about what students know and can do. Knowing What Students Think 2/26/03

Interpretation (Item Analysis)
45%: it will weigh less because no air pressing down on it. 25%: it will weigh more because no air under scale holding it up. 30%: it will weigh the same because the removal of the up & down force of air pressure balance out
A block on a scale weighs 10lb. If the scale and the block are covered and sealed & all the air is removed, how much will the block weigh?
Why?
Cognition
Prior belief - Air pressure affects weight of objects

Assessment Question:
Question: What was the date of the battle of the Spanish Armada? Student 1: 1588 [correct]
Student 2: Around 1590 [close but incorrect]
What learning objective does this question address?
•What does this tell us about their level of knowledge of the event? •What does this tell us about the students’ representations and organization of knowledge? •What does this tell us about their ability to use evidence to make inferences, draw conclusions? •How would student Knowing What Students Think performance impact further

Assessment Question Revised
Give the date of the Spanish Armada and provide some historical evidence that would support your answer. Student 1: 1588 - I memorized it from the textbook. Student 2: Around 1590. The English began to settle Virginia just after 1600, not sure of the exact date. They wouldn’t have dared start overseas exploration if Spain still had control of the seas because of the danger and potential loss of money, ships, etc. It would take awhile to get expeditions organized, so England must have gained naval supremacy around the late 1500s.

Using rubrics to assess performance
What is a rubric?
A rubric is the scoring rules or criteria against which student work will be judged. One purpose of a rubric is to make public the key criteria that students can use in developing, revising, and judging their own work.

Components of a Rubric
Levels of Mastery
Classification of performance. Excellent, Good, Needs Improvement, Unacceptable, Exemplary, Proficient, Acceptable, Unacceptable.
Listing of the components that comprise quality performance E.g., written communication, logical reasoning, executing ANOVA
Dimensions of Quality
Organizational Groupings
Skill dimensions subdivided into component skills. E.g., Written communication maybe assessed on grammar, organization, appropriateness for audience, use of evidence, documenting sources, etc)
Commentaries
Information on the critical features& standards for each of the mastery levels. e.g., translation task: “Excellent” in grammar: “no grammatical or spelling errors, uses most appropriate sentence structure, etc, “Good”: “few minor grammatical and spelling errors, occasional awkwardness in sentence construction, etc.

Why do Assessment-driven instruction?
It helps us to design tests, homework and practice activities that are better aligned with desired outcomes.
Avoid the pitfall of busywork
It provides instructors with a clearer view of how to design and structure instructional activities to better support student learning toward meeting performance objectives It helps us more clearly explain and justify to ourselves and students the purposes and goals of instructional and assessment activities
