Can We Believe Our Eyes?
Before we see the video, I want you to draw a diagram showing how you could light a bulb with one battery and one wire.

Understanding Understanding
Up until now we assumed that we all shared a common understanding of the meaning of the word understanding.
But what are you really aiming for when your goal is understanding?

Understanding Understanding
Teachers want their students to understand the concepts they are
teaching.
…a slippery goal without definitions.
Also, are there different levels of understanding?
![Page 17: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/17.jpg)
Benjamin Bloom 1913-1999
his Taxonomy of Educational Objectives was
…an attempt to classify different degrees of understanding.

Bloom’s Contributions
Bloom’s Taxonomy
Research on early childhood; testified on behalf of Head Start
International influence
Mastery learning
Gifted students; all students have innate potential

Bloom’s BiographyBorn 1913, in Lansford, PA
BA & MS in 1935 from Penn State University
PhD in 1942 from University of Chicago
Lived in Chicago at time of death in 1999
![Page 20: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/20.jpg)

Career Beginnings
Staff member of Board of Examinations at the University of Chicago, 1940-43
Under mentorship of Ralph W. Tyler
Growing interest in organizing educational objectives by cognitive complexity
Became University Examiner in 1943(In this position, he developed tests to determine if undergraduates had mastered material necessary for them to receive their bachelor’s degrees.)
![Page 21: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/21.jpg)
21
Developing the Taxonomy
Bloom attended the American Psychological Association convention in 1948…
His discussions with other university examiners lead to the
utility of a hierarchical classification system for various educational goals
![Page 22: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/22.jpg)
22
Developing the Taxonomy
They wanted to:
clarify language about educational objectives
have convenient system for describing test items, exam techniques, and instruments for assessment
be able to compare and study educational programs
show a real order among educational objectives
![Page 23: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/23.jpg)
23
Developing the Taxonomy
Continued to meet after convention
Defined three “domains” or classifications for educational objectives:
Cognitive
Affective
Psychomotor
Formed committees of study for each
![Page 24: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/24.jpg)
24
The Cognitive Domain
1956 book, Bloom as editor with Engelhart, Furst, Hill + Krathwohl
Focus on students’ thought processes
Taxonomy:
Hierarchical according to cognitive levels of difficulty
Each level encompasses, builds on and is more difficult than that at the levels below it
![Page 25: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/25.jpg)
25
The Cognitive Domain
There are three low-level orders: Knowledge
Recognition/recall of information Remember just as learned
Comprehension Organize and arrange information Rephrase (describe in own words)
Application Apply information to find answer to problem Apply rule or process to new situation
![Page 26: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/26.jpg)
26
The Cognitive Domain
There are three higher-level orders:Analysis
Think critically, in depth; no rule of thoughtIdentify reasons, uncover evidence, make conclusions
SynthesisPerform original and creative thinkingProduce new material, predict, problem-solve
EvaluationJudge merit, offer an opinion, assessNot careless critique: according to a standard
![Page 27: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/27.jpg)

Using Bloom’sTaxonomy in the Classroom How do you use
Bloom’s Taxonomy?
Classify educational objectives
Plan to help students achieve higher levels of mastery
Structure questioning and assessments
![Page 29: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/29.jpg)
29
Critizing Bloom’s Taxonomy
Synthesis and evaluation are one and the same
Synthesis and evaluation should be switched
No past history or context
Some knowledge is harder to retain; some knowledge is harder to restate in ways that prove comprehension

33
Using Bloom’sTaxonomy in the Classroom
Application: What kind of homework might I give to test your ability to apply what you’ve learned today about Bloom’s Taxonomy?
![Page 34: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/34.jpg)

35
Using Bloom’sTaxonomy in the Classroom
Evaluation: Based on your knowledge and experience, would you recommend Bloom’s Taxonomy to other teachers? Why or why not?
![Page 36: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/36.jpg)
36
Using Bloom’sTaxonomy in the Classroom
Creating: Any ideas on how to ask a class to create a product related to Bloom’s Taxonomy?

Understanding Understanding
Understanding and Apparent Understanding
What would you find if you dug a hole in the earth? John Dewey (See page 48 of Understanding by Design.)
If students have trouble answering this question, is it the wrong question?
![Page 39: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/39.jpg)
39
Understanding Understanding
What evidence of understanding is adequate?
Is knowing facts and doing well on a test of knowledge the same thing as understanding?
![Page 40: PSPH 228 Assessment in K-12 Science Education Fall 2010](https://reader034.vdocuments.mx/reader034/viewer/2022042822/56814453550346895db0ef60/html5/thumbnails/40.jpg)

Understanding Understanding
Apparent Understanding
Delivery of the right word, the right definition, the correct formula.
…using learning in new ways. (Bloom’s Taxonomy)
…the ability to think and act flexibly with what one knows. (David Perkins)
Real Understanding

41
Understanding is About Transfer
When we understand something we can use it in new settings.
We can take what we know and use it in numerous ways!
Understanding is about
Transfer!

Understanding is Not About Inert Ideas!
What are inert ideas? (p. 41)

Misunderstanding Provides Insight
Misunderstanding Is Not Ignorance
Misunderstandings are ideas that are mapped on plausible but incorrect frameworks.
It takes a fair amount of knowledge to misunderstand something.
Students often think that experimental error happens because of avoidable mistakes in
procedure and/or measurement.

Misunderstanding Provides Insight
Conventional testing reveals the problem:
Most US teenagers study and pass Algebra 1. Yet, NAEP results show that only 5 percent of our students perform at a proficient level on tasks that require higher-order use of Algebra 1 knowledge (NAEP, 1988).

Six Facets of Understanding
Group Activity –
• Fellows will work together in small groups (3 or 4) to develop 10 – 15 minute presentations on one of the six facets of understanding.
• Groups will present their findings using PowerPoint or other visual aid.
• Each group will provide a handout describing one facet of understanding, with examples, and 2 exam questions.
• Groups will divide the task into explicit responsibilities for each person in the group.
