Teaching and Math
Methodology
The Role of Assessment
Anne Davies (2004) states key tenets on the role of assessment,
which illustrate the partnership that should exist between teaching and
learning. "Keeping students informed about the learning objectives or
standards they are working toward helps support their success. Quality and
success also become clearer for students when we engage them in setting
criteria" (p. 2). Thus, assessment is more than collecting data on test
performance.
Davies (2004) indicates that assessment is a process of triangulation or
gathering evidence over time that agreed-upon criteria have been met from
multiple sources: artifacts that students produce, observation notes on the
process of students' learning, and documentation from talking with students
about their learning. Assessment includes guiding students to self-assess
their learning, involving parents and students in discussions of progress, and
students showing evidence of their learning to audiences they care about. It is
a complex process because of differences in learning styles, multiple
intelligences, and the diverse backgrounds that students bring to classrooms
(2004).
With the current focus on assessment using standardized testing,
educators might have overlooked the value of performance assessments, which also
provide evidence of what students can do. Such evidence of student
artifacts gathered over time, as Davies (2004) notes, is clearly evident in
Edutopia's video:
Assessment Overview: Beyond Standardized Testing. It will definitely
give you ideas for your own classroom.
The following sections address systems for assessment (diagnostic,
formative, summative), more on self-assessment, teacher-made tests, and
vendor-made tests.
Systems
There are two kinds of tests that may or may not help a teacher to do a better
instructional job: teacher-made classroom tests and externally imposed tests,
"those tests required by state or district authorities and designed by
professional test developers to measure student mastery of the sets of
objectives experts have deemed essential" (Popham, 2003, section: Preface).
The
accountability movement has placed a great deal of stress upon teachers to
prepare students for those state standardized tests and even greater stress upon
students to perform well on those tests, which are now mandated by the No Child
Left Behind legislation. To this end, Popham (2007) suggests that schools
also need interim tests that they "can administer every few months to predict
students' performances on upcoming accountability tests" (p. 80).
The Association for Supervision and Curriculum
Development (Carter, 2004) supports using multiple measures in assessment
systems, rather than reliance on the outcome of a single test, to accurately
measure achievement and to hold stakeholders accountable. Such assessment systems are
-
Fair, balanced, and grounded in the art and science of
learning and teaching;
-
Reflective of curricular and developmental goals and
representative of content that students have had an opportunity to learn;
-
Used to inform and improve instruction;
-
Designed to accommodate nonnative speakers and special needs
students; and
-
Valid, reliable, and supported by professional, scientific,
and ethical standards designed to fairly assess the unique and diverse
abilities and knowledge base of all students (para. 9).
In Inside the black box: Raising standards through classroom
assessment, Paul Black and Dylan Wiliam (1998) stated from the TIMSS video
study, "A focus on standards and accountability that ignores the processes
of teaching and learning in classrooms will not provide the direction that
teachers need in their quest to improve" (para. 2). Those
processes involve teachers making assessment decisions, which W. James Popham
(2003) indicates can be made based on the structure of the tests themselves or
on students' performance on those tests. Teachers can make decisions
about the nature and purpose of the curriculum, about students' prior knowledge,
about how long to teach something, and about the effectiveness of instruction
(Chapter 1, section: What Sorts of Teaching Decisions Can Tests Help?)
Sometimes state and district content standards are not worded
clearly enough for use at the classroom level and lead to possible multiple
interpretations. Hence, Popham (2003, Chapter 1) points out the need for
teachers to examine test sample items to clarify the intent of a particular
curricular goal. They can then focus instruction appropriately on that
intent.
How teachers use assessment plays a major role in achieving
standards. Assessments can be
diagnostic, formative, and summative. As you read about those categories
in what follows, consider the seven assessment and grading practices for
effective learning suggested by Jay McTighe and Ken O'Connor (2006):
-
Use summative assessments to frame meaningful
performance goals. ... To avoid the danger of viewing the standards and
benchmarks as inert content to “cover,” educators should frame the
standards and benchmarks in terms of desired performances and ensure
that the performances are as authentic as possible. Present those
tasks at the beginning of a new unit.
-
Show criteria and models in advance. Rubrics and
multiple models showing both strong and weak work help learners judge
their own performances.
-
Assess before teaching.
-
Offer appropriate choices. While keeping goals in
mind, options judiciously offered enable students different
opportunities for best demonstrating their learning.
-
Provide feedback early and often. Learners will
benefit from opportunities to act on the feedback—to refine, revise,
practice, and retry.
-
Encourage self-assessment and goal setting.
-
Allow new evidence of achievement to replace old
evidence. (pp. 13-19)
Diagnostic Assessment
The diagnostic assessment, typically given at the beginning of
an instructional unit or school year, will determine students' prior knowledge, strengths,
weaknesses, and skill level. It will help you to adjust curriculum or
provide for remediation. According to Tomlinson and McTighe (2006), they
can also help "identify misconceptions, interests, or learning style
preferences," and help with planning for differentiated instruction.
Assessments might take the forms of "skill-checks, knowledge surveys, nongraded
pre-tests, interest or learning preference checks, and checks for
misconceptions" (p. 71). Thus, pretests help "to isolate the things your
new students already know as well as the things you will need to teach them" (Popham,
2003, Chapter 1, section: Using Tests to Determine Students' Entry Status).
Further, "A pretest/post-test evaluative approach ... can contribute
meaningfully to how teachers determine their own instructional impact" (Chapter
1, section: Using Tests to Determine the Effectiveness of Instruction).
Progress Monitoring: A Component of Responsiveness to
Intervention
The point of a diagnostic is not just to assess, but to do
something with test results leading to improved learning. Thus, progress
monitoring with individual students or an entire class makes sense.
According to the National
Center on Student Progress Monitoring, progress monitoring is "a
scientifically based practice." The term is relatively new, and educators
might be more familiar with Curriculum-Based Measurement and Curriculum-Based
Assessment. An implementation involves determining a student’s current
levels of performance and setting goals for learning that will take place over
time. "The student’s academic performance is measured on a regular basis (weekly
or monthly). Progress toward meeting the student’s goals is measured by
comparing expected and actual rates of learning. Based on these measurements,
teaching is adjusted as needed. Thus, the student’s progression of achievement
is monitored and instructional techniques are adjusted to meet the individual
students learning needs" (NCSPM, sec: Common Questions).
Although NCSPM does not endorse specific products, it has
identified tools (based on its annual reviews) that demonstrate sufficient
evidence for its progress monitoring standards. Among those for math are
Renaissance Learning's Accelerated Math and
STAR Math, CTB/McGraw-Hill's
Yearly Progress Pro, and
Monitoring Basic Skills Progress (MBSP
Basic Math) from Pro-Ed. These are representative of progress
monitoring products.
Progress monitoring is one component of Responsiveness to
Intervention (RTI), which is an education model for early identification of
students at risk for learning disabilities. Of equal importance is the
emphasis on providing appropriate learning experiences for all students by
ensuring "current levels of skill and ability are aligned with the instructional
and curricular choices provided within their classroom" (National Research Center
on Learning Disabilities [NRCLD], n.d., sec: What is RTI?). The NRCLD
provides extensive information on RTI and the how to's of progress monitoring.
Formative Assessment
Formative assessment is assessment for learning. In their
Central
Michigan University Assessment Toolkit, Burns et al. (n.d.) indicate that
formative assessments provide immediate evidence of student learning, and can be
used to help improve upon quality of instruction and to monitor progress in
achieving learning outcomes. It "is an essential component of classroom
work and its development can raise standards of achievement” (Black & Wiliam,
1998, section: Are We Serious About Standards?, para. 2).
"Formative assessment includes both formal and informal methods,
such as ungraded quizzes, oral questioning, observations, draft work, think-alouds,
student constructed concept maps, dress rehearsals, peer response groups, and
portfolio reviews" (Tomlinson & McTighe, 2006, p. 71), and conferences.
Students might write their understanding of vocabulary or concepts before
and after instruction, or summarize the main ideas they've taken away from a
lecture, discussion, or assigned reading. They can complete a few problems or questions at the end of
instruction and check answers. Teachers can interview students individually or in groups about their thinking as
they solve problems, or assign brief, in-class writing assignments (Brown,
2002, section: Examples of
Formative Assessment).
These writing assignments, accompanied by peer group
discussions, are essential, as "Knowledge and thinking must go hand in hand" (McConachie
et al., 2006, p. 8). Embedding writing in performance tasks enables
teachers to "guide students to deeper levels of understanding" (p. 12).
McConachie et al. provided the following example, appropriate for a grade 7 math
unit on percents:
To celebrate your election to the student council, your
grandparents take you shopping. You have a 20-percent-off coupon.
The cashier takes 20 percent off the $68.79 bill. Your grandmother
remembers that she has an additional coupon for 10 percent off. The
cashier takes the 10 percent off what the case register shows. Does
this result in the same amount as 30 percent off the original bill?
Explain why or why not? (p. 12).
In determining if students truly understand percents in the
above example, teachers are assessing if students know what a percent is, if
they can use percents in a real-world application, and interpret their answers
appropriately.
The RAFT method is a particularly useful formative assessment
writing strategy for checking understanding. According to Douglas Fisher
and Nancy Frey (2007), RAFT prompts ask students to consider the role of the
writer (R), the audience (A) to whom the response is written, the format (F) of
the writing, and the topic (F) of the writing. For example, to determine if
students understand characteristics of triangles, one such prompt might be:
R: Scalene triangle
A: Your angles
F: Text message
T: Our unequal relationship (p. 69).
Denise Anthony and Linda MacKenzie (2003, p. 3) suggest other
examples, such as:

Black and Wiliam (1998) provide the following suggestions for
improving formative assessment (section: How can we improve formative
assessment?):
-
In terms of building self-esteem in
pupils, “feedback to any pupil should be about the particular qualities
of his or her work, with advice on what he
or she can do to improve, and should avoid comparisons with other pupils”
(para. 3).
-
Self-assessment by
pupils is an essential component in formative assessment, which involves
three components: students must recognize the
desired goal, have evidence
about their present position,
and some understanding of a way to
close the gap between the two. “[I]f
formative assessment is to be productive, pupils should be trained in
self-assessment so that they can understand the main purposes of their
learning and thereby grasp what they need to do to achieve” (para.
7).
In terms of effective
teaching:
-
“[O]pportunities
for pupils to express their understanding should be designed into any piece
of teaching, for this will initiate the interaction through which formative
assessment aids learning”
(para. 9).
-
“[T]he dialogue between pupils
and a teacher should be thoughtful,
reflective, focused to evoke and explore understanding, and conducted so
that all pupils have an opportunity to think and to express their ideas”
(para. 13).
-
"[F]eedback
on tests, seatwork, and homework should give each pupil guidance on how to
improve, and each pupil must be given help and an opportunity to work on the
improvement” (para. 15).
Stephen Chappuis and Jan Chappuis (2007/2008) say that a key
point on the nature of formative assessment is that "there is no final mark on
the paper and so summative grade in the gradebook" (p. 17). The intent of
this type of assessment for learning is for students to know where they
are going in terms of learning targets they are responsible for mastering, where
they are now, and how they can close any gap. "It functions as a global
positioning system, offering descriptive information about the work, product, or
performance relative to the intended learning goals" (p. 17). Such
descriptive feedback identifies specific strengths, then areas where improvement
is needed, and suggests specific corrective actions to take. For example,
in a study of graphing, an appropriate descriptive feedback statement might be
"You have interpreted the bars on this graph correctly, but you need to make
sure the marks on the x and y axes are placed at equal intervals" (p. 17).
Notice that the statement does not overwhelm the student with more than he/she
can act on at one time.
Corrective Activities in Formative Assessment
Thomas Guskey (2007/2008) points out that formative assessments
will not necessarily lead to improved student learning or teacher quality
without appropriate follow-up corrective activities after the assessments.
These activities have three essential characteristics. They present
concepts differently, engage students differently in learning, and provide
students with successful learning experiences. For example, if a concept
was originally taught using a deductive approach, a corrective activity might
employ an inductive approach. An initial group activity might be replaced
by an individual activity, or vice versa. Corrective activities can be
done with the teacher, with a student's friend, or by the student working alone.
As learning styles vary, providing several types of such activities to give
students some choice will reinforce learning (pp. 29-30).
Guskey (2007/2008) suggests
several activities to consider, which are included in the following table.
He recommends these be done during class time to ensure those who need them the
most will take part.

Enrichment Activities in Formative Assessment
According to Guskey (2007/2008), some students will demonstrate
mastery of concepts on an initial formative assessment. These students are ideal
candidates for enrichment activities while others are engaged in corrective
activities. "Rather than being narrowly restricted to the content of
specific instructional units, enrichment activities should be broadly construed
to cover a wide range of related topics" (p. 32). As with corrective
activities, students should have some freedom to choose an activity that
interests them. Teachers might consider having students produce a product
of some kind summarizing their work. This enhances the experience so that
students don't construe the time spent as busy work.
Summative Assessment
Unlike formative assessment, which is assessment for
learning, summative assessment is assessment of learning. According
to Burns and colleagues (n.d.), these assessments are comprehensive, typically
given at the end of a program, and provide for accountability. Such judgments include grading a paper or test, for example.
Traditional assessments might include multiple choice,
true/false, and matching. However, consider alternative assessments such
as short answer questions, essays, electronic or paper-based portfolios, journal writing, oral
presentations, demonstrations, creation of a product, student self-assessment
and reflections, and performance tasks that are assessed by predetermined
criteria. [Note: You will find more about performance tasks in CT4ME's
section on curriculum mapping.] Self and peer
assessments can be both formative and summative in nature, and help students to
take responsibility for and to become critical of their own work.
In their definition of performance assessment, the Association
for Supervision and Curriculum Development (n.d.) states, "Performance tasks
often have more than one acceptable solution; they may call for a student to
create a response to a problem and then explain or defend it. The process
involves the use of higher-order thinking skills (e.g., cause and effect
analysis, deductive or inductive reasoning, experimentation, and problem
solving)" (para. 3). Conrad and Donaldson (2004) characterize an authentic
activity as one that "simulates an actual situation" and "draws on the
previous experiences of the learners" (p. 85). They posed six questions to
guide educators who design such activities:
-
Is the activity authentic?
-
Does it require learners to work collaboratively and use
their experiences as a starting point?
-
Are learners allowed to learn from their mistakes?
-
Does the activity have value beyond the learning setting?
-
Does the activity build skills that can be used beyond the
life of the course?
-
Do learners have a way to implement their outcomes in a
meaningful way? (p. 86).
The School of Education at the University of Wisconsin-Stout has
an extensive collection of
authentic assessment resources and rubrics.

A Note on Real-World Contexts
According
to the National Mathematics Advisory Panel (2008):
The use of “real-world” contexts to introduce
mathematical ideas has been advocated, with the term “real
world” being used in varied ways. A synthesis of findings from a
small number of high-quality studies indicates that if
mathematical ideas are taught using “real-world” contexts, then
students’ performance on assessments involving similar
“real-world” problems is improved. However, performance on
assessments more focused on other aspects of mathematics
learning, such as computation, simple word problems, and
equation solving, is not improved. (p. xxiii)

More on Self-Assessment
Learning how to self-assess is an incremental process that can
begin with the elementary grades. Heidi Andrade (2007/2008) says, "During
self-assessment, students reflect on the quality of their work, judge the degree
to which it reflects explicitly stated goals or criteria, and revise.
Self-assessment is formative...Self-evaluation, in contrast, is summative--it
involves students giving themselves a grade" (p. 60).
For self-assessment to be meaningful to students,
they must prove to themselves that it can make a difference in their learning.
Alison Preece (1995) provides eight tips for success. Teachers might point
out that payoff, start small and keep things simple, build self-[assessment] into
day-to-day activities, make it useful, clarify criteria, focus on strengths,
encourage variety and integrate self-[assessment] strategies with peer and teacher
[assessment], and grant it a high profile (p. 30). Tomlinson and McTighe
(2006) say that "self-assessment in a differentiated classroom also enables
student and teacher to focus both on nonnegotiable goals for the class and
personal or individual goals that are important for the development of each
learner" (p. 80).
To ease students into the process of evaluation, students might
first evaluate the materials they use and activities in which they are involved.
Teachers might ask for suggestions for improvement of lessons they have
presented, peers might comment on work of others by acknowledging what was good
and providing a suggestion for a change or addition (Preece, 1995).
Eventually students would "try a variety of strategies such as learning logs,
conference records, response journals, self-report sheets, attitude surveys, and
portfolio annotations" (p. 33). Teachers might encourage them to come up
with questions on "attitudes, strategies, stumbling blocks, and indicators of
progress or achievement" (p. 35). Students might write one or two
statements of meaningful goals for themselves with some strategies for achieving
them. The key for success on this latter is follow-up to monitor progress
toward those goals with negotiated check-in times for discussion, including
possible refinement or replacement.
To help students develop their personal accountability for
learning, Preece (1995) suggests that teachers might require students to keep a
record book with books/content read, completed assignments, projects, personal
goals, accomplishments and what is working well, challenges to learning, and
difficulties encountered. This serves as a basis for conferences, either
with the teacher or with parents. In either case, students use this tool
and lead those conferences to report their progress on learning.
Rubrics in Self-Assessment
Rubrics are not just for evaluation (i.e., assigning a grade) of
student work. They are excellent tools to use for self- and
peer-assessment, orienting students to what constitutes quality from the
viewpoint of experts and serving as guides for revision and improvement.
They are particularly valuable when students have input into their construction.
When they use them to monitor their progress on an assignment, they might
underline key phrases in the rubric, perhaps with a colored pencil, and then use
that same color to underline or circle those parts in their draft work that meet
the standard identified in the rubric. If they can't find where in their
work that they have met the standard, they will immediately know that revision
is needed (Andrade, 2007/2008). The key to success when using rubrics is
to build time for revision into the learning plan.
The design of the rubric is also crucial. Rubrics add the
objective component to assessment and evaluation. Caution should be
exercised on their use in evaluation. If a typical rubric has five to
seven categories, some criteria of value (e.g., originality) to a grader might
not be among those. The unique perspective of students and their
creativity might be thwarted in self-assessing their own work using only the
standards on the rubric. Maja Wilson (2007/2008) points out the importance
of dialogue as an assessment tool. Where "ideas, expertise, intent and
audience matter...a conversation is the only process responsive enough to expose
the human mind's complex interactions with language" (p. 80). Dialogue is
just as important as using the rubric in assessment, and may lead to changes in
the rubric itself as teachers collaborate with their students.

Teacher-Made Tests
According to Popham (2003), the purposes of classroom tests
vary, but prior to constructing any test, teachers should first identify the
kinds of instructional decisions that will be made based on test results, and
the kinds of score-based inferences needed to support those decisions.
Teachers would be most interested in the content validity of their tests and how
well their test items represent the curriculum to be assessed, which is
essential to make accurate inferences on students' cognitive or affective
status. "There should be no obvious content gaps, and the
number and weighting of items on a test should be representative of the
importance of the content standards being measured" (Chapter 5, section: All
About Inferences).
Test items can be classified as selected-response (e.g.,
multiple-choice or true-false) or constructed-response (e.g., essay or
short-answer). When constructing either type, Popham (2003) offers five pitfalls
to avoid, all of which interfere with making accurate inferences of students'
status. They are "(1) unclear directions, (2) ambiguous
statements, (3) unintentional clues, (4) complex phrasing, and
(5) difficult vocabulary (Chapter 5, section: Roadblocks to Good
Item-Writing). Students would benefit by knowing the differential
weighting of questions and time limits in the directions. Ambiguity would
be lessened with clearly referenced pronouns when used, and phrases that have
singular meanings. Items should be written without obvious clues as to the
correct answer. Examples of unintentional clues include the correct
answer-option written longer than the incorrect answer-options or grammatical
tip-offs (e.g., never, always).
Illustrating
Popham's (2003) pitfalls to avoid, Fisher and Frey (2007, p. 107) provided an
example showing the difficulty in writing test stems for multiple-choice items.
A student looks at a right triangle with legs marked as 5 cm each. The
intention is for the student to find the length of the missing hypotenuse, as
shown. Consider the following stems: "Find X." and "Calculate the
hypotenuse (X) of the right triangle." A middle school student who is at
the beginning stages of learning English might circle the X. He has found
it! However, it is the latter choice that was intended, and is, therefore,
the better unambiguous stem for the question.
Back to top
Vendor-Made Tests
According to Popham (2007), assessments for the most part should
be supplied to teachers, rather than having them create their own.
However, "many vendors are not providing the sorts of assessments that educators
need" (p. 80). For classroom use, formative diagnostic and interim
predictive for upcoming accountability tests are most in demand, as well as
"instructionally sensitive accountability tests that can accurately evaluate
school quality" (p. 80). Teachers must be able to evaluate a vendor's test
to determine if it fulfills the role that it is intended to serve. In
doing so, Popham suggests that teachers keep the following questions in mind:
-
Does the test measure a manageable number of instructionally
meaningful curricular aims?
-
Do the descriptive materials accompanying the test clearly
communicate the test's assessment targets?
-
Are there sufficient items on the test that measure each
assessed curricular aim to let teachers and students know whether a student
has mastered each skill or body of knowledge?
-
Are the items on the test more likely to assess what a
student has been taught in school rather than what that student might have
learned elsewhere? (p. 82).

Consider having students use an e-portfolio for
documenting their progress toward mastering state standards.
What
is an e-portfolio? George Lorenzo and John Ittelson (2005)
define an e-portfolio as "a digitized collection of artifacts,
including demonstrations, resources, and accomplishments that
represent an individual, group, community, organization, or
institution. The collection can be comprised of text-based,
graphic, or multimedia elements archived on a Web site or on other
electronic media such as CD-ROM or DVD" (p. 2).
In
Digital-Age Assessment, Harry Tuttle (2007) recommends using
e-portfolios as a method to look beyond traditional assessment.
"A common e-portfolio format includes a title page; a standards'
grid; a space for each individual standard with accompanying
artifacts and information on how each artifact addresses the
standard; an area for the student's overall reflection on the
standard; and a teacher formative feedback section for each
standard. Within the e-portfolio, the evidence of student learning
may be in diverse formats such as Web pages, e-movies, visuals,
audio recordings, and text" (sec: Getting Started). Portfolio
Assessment from Prince George's County Public Schools (MD) contains a
collection of resources linking portfolios to instruction. Learn what a
portfolio is and why to use it, characteristics of an effective portfolio, the
different types of portfolios, phases of development, and how to evaluate.
