Title: How do we know what they know
1How do we know what they know?
- FASS Meeting
- Orlando, FL
- April 5, 2004
- Arthur Eisenkraft (eisenkraft_at_att.net)
2Are we listening?
- The optometrist
- The Duracell competition
- Two objects falling in a vacuum
- The cord of wood
3No Child Left Behind
- Enormous concern about NCLB and other high stakes
assessments. - NCLB a potential nightmare
- AYP - need of improvement
- public embarrassment
- best students leaving and the scores dropping
more, closing of schools. - What can we do?
- This year alone 26,100 of the nations 91,400
have been labeled schools that need
improvement. (Sam Dillon, 1 in 4 Schools Fall
Short Under Bush Law, N.Y. Times, January 27,
2004 at A21)

5The Deborah Meier Amendment
- A basic test should first be taken by the folks
we honor by electing to office. - The people who legislate or mandate a test should
be required first to take it themselves to ensure
that it's measuring what they think it is. It's a
form of validity checking. - They might even have their scores posted!

11Classroom Assessment
- The Grade Book
- Tests
- Quizzes
- Homework
- Class participation (?)
- Lab reports
- Attendance (X)
- Projects
- The Final Exam
- Local
- State High stakes
- These are often treated as summative though they
do inform as formative. - Other formative assessments include
- Questions in class
- Practice tests
12Get tests back immediately
- They can then be used for formative assessment.
- How can anyone continue instruction when you have
a tool that informs you of student understanding? - Easily measured by supervisors and students alike
13Formative Assessment
- The value of formative assessment (Paul Black)
students often have limited opportunities to
understand or make sense of topics because many
curricula have emphasized memory rather than
understanding. Textbooks are filled with facts
that students are expected to memorize, and most
tests assess students abilities to remember the
facts.

51The Assessment Triangle
- cognition, observation, and interpretationmust
be explicitly connected and designed as a
coordinated whole. If not, the meaningfulness of
inferences drawn from the assessment will be
compromised.
C O
I
52Assessment 1
- Question What was the date of the battle of the
Spanish Armada? - Answer 1588 correct.
- Question What can you tell me about what this
meant? - Answer Not much. It was one of the dates I
memorized for the exam. Want to hear the others?
53Assessment 2
- Question What was the date of the battle of the
Spanish Armada? - Answer It must have been around 1590.
- Question Why do you say that?
- Answer I know the English began to settle in
Virginia just after 1600, not sure of the exact
date. They wouldnt have dared start overseas
explorations if Spain still had control of the
seas. It would take a little while to get
expeditions organized, so England must have
gained naval supremacy somewhere in the late
1500s.
54Comparison
- Most people would agree that the second student
showed a better understanding of the Age of
Colonization than the first, but too many
examinations would assign the first student a
better score. - When assessing knowledge, one needs to understand
how the student connects pieces of knowledge to
one another. Once this is known, the teacher may
want to improve the connections, showing the
student how to expand his or her knowledge.
55Formative Assessment Research
- Black and Wiliam (1998) provide an extensive
review of more than 250 books and articles
presenting research evidence on the effects of
classroom assessment. - They conclude that ongoing assessment by
teachers, combined with appropriate feedback to
students, can have powerful and positive effects
on achievement. - They also report, however, that the
characteristics of high-quality formative
assessment are not well understood by teachers
and that formative assessment is weak in
practice. High-quality classroom assessment is a
complex process
56Return to bad practice
- We revert back to old, failed strategies when
under pressure - Comfort food
- In dealing with our children
- Youll poke your eye out
- What if everybody jumped off the Empire State
Building? - Prison, drug addiction
57Responding to the pressure (NCLB, FCAS)
- If you go back to the worksheets and it doesnt
work, you wont be blamed in the same way because
this is what everybody does. - If you continue with something that is closer to
the edge, you are more open to criticism - This could be the reason for the blame
- Fail forward as Thomas Edison did
58Support our teachers
- Help them to not succumb to the pressures.
- Encourage them to improve their instruction, not
to revert to poor pedagogy. - Give them permission to be better teachers.
59Questions that foster deep understanding rather
than questions that ask for repetition of
memorized information and conclusions. (Jim
Minstrell and Emily van Zee)
- Ask or promote questions to open an inquiry and
elicit students initial understanding and
reasoning. - Ask or promote questions to interpret and make
sense of data in order to generate new knowledge
and understanding. - Ask or promote questions to clarify or elaborate
on observations and inferences. - Ask or promote questions to encourage learners to
justify their answers and conclusions or to
explain their reasoning to go beyond a mere
stating of an answer. - Ask or promote questions to extend or apply
learned ides. - Ask or promote questions that help learners
monitor their own learning.
60Understanding by Design
- When do we generate test questions
- UbD (Grant Wiggins, Jay McTighe)
- Enduring understandings
- Evidence
- Instruction
61Not in vain
- When studying about veins and arteries, for
example, students may be expected to remember
that - arteries are
- thicker than veins,
- more elastic, and
- carry blood from the heart
- veins carry blood back to the heart.
62Sample test item
- Arteries
- a. Are more elastic than veins
- b. Carry blood that is pumped from the heart
- c. Are less elastic than veins
- d. Both a and b
- e. Both b and c
63The new science of learning
- does not deny that facts are important for
thinking and problem solving. - Research on expertise in areas such as chess,
history, science,and mathematics demonstrate that
experts abilities to think and solve problems
depend strongly on a rich body of knowledge about
subject matter (e.g.,Chase and Simon,1973Chi et
al.,1981deGroot,1965).
64Facts are not enough
- However,the research also shows clearly that
usable knowledge is not the same as a mere
list of disconnected facts. - Experts knowledge is
- connected and organized around important concepts
(e.g., Newton s second law of motion) - conditionalized to specify the contexts in
which it is applicable - supports understanding and transfer (to other
contexts) rather than only the ability to
remember.
65Vein and artery experts
- Know the facts in the mc question
- also understand why veins and arteries have
particular properties. - They know that blood pumped from the heart exits
in spurts - That the elasticity of the arteries helps
accommodate pressure changes. - They know that blood from the heart needs to move
upward (to the brain) as well as downward and
that the elasticity of an artery permits it to
function as a one-way valve that closes at the
end of each spurt and prevents the blood from
flowing backward. - They are better able to transfer
- Design an artificial artery strong enough to
handle pressure with or without elasticity
(Bransford and Stein,1993).
66Classroom environments
- Formative assessmentsongoing assessments
designed to make students thinking visible to
both teachers and students are essential. - They permit the teacher to
- grasp the students preconceptions,
- understand where the students are in the
developmental cor-ridor from informal to formal
thinking, and - design instruction accordingly.
- In the assessment-centered classroom environment,
formative assessments help both teachers and
students monitor progress.
67Learner friendly assessments
- Provide students with an opportunity to revise
and improve their thinking (Vye et al.,1998b), - help students see their own progress over the
course of weeks or months - help teachers identify problems that need to be
remedied (problems that may not be visible
without the assessments). - Problem based learning model
- Sport for the moon
68Defining Science Content
- Facts, process, knowledge
- Order of the planets
- I went to a two day history seminar and there was
no content I didnt learn any new dates. - Where is the knowledge we have lost in
information. (T.S. Eliot)
69Wait time study at Kings College (Black
Wiliam, 2000)
- Questions opened up discussion that helped expose
and explore students assumptions and reasoning. - At the same time, wrong answers became useful
input, and the students realized that the teacher
was interested in knowing what they thought, not
in evaluating whether they were right or wrong. - As a consequence, teachers asked fewer questions,
spending more time on each.
70Wait time study at Kings College (Black
Wiliam, 2000)
- In addition, teachers realized that their lesson
planning had to include careful thought
about the selection of informative questions. - They discovered that they had to consider very
carefully the aspects of student thinking that
any given question might serve to explore. - This discovery led them to work further on
developing criteria for the quality of their
questions.
71Grades vs. comments
- Simply giving grades on written work can be
counterproductive for learning (Butler, 1988) - In response, teachers began instead to
concentrate on providing comments without
gradesfeedback designed to guide students
further learning. - Students also took part in self-assessment and
peer-assessment activities, which required that
they understand the goals for learning and the
criteria for quality that applied to their work. - In these ways, assessment situations became
opportunities for learning, rather than
activities divorced from learning.
72Sliding toward Socrates
- Follow-up research
- Grades vs. comments vs. grades comments
- No distinction between instruction and assessment

effective at improving student achievement. - Help teachers learn Testing for understanding
techniques. - Provide teachers with the confidence and support
to continue to improve their teaching and resist
the temptation to revert to poor pedagogy and
worksheets in attempts to deal with NCLB. - Give them permission to be good teachers.

87Unscrambling Confusion
- Determining what students dont understand
implies that teachers have ways of unscrambling
confusions that identify the specific point(s) of
misunderstanding and deal with them. - What means do we have for unscrambling
confusions?

students performance, - an interpretation method for drawing inferences
from the performance evidence thus obtained.
