SCIENCE ASSESSMENT PROJECT
FIRST GRADE PROTOTYPE
Dear First Grade Teacher,
These materials are provided for you in the hope that as you use
them you will better understand how to measure what your students
are learning in science. The materials have been prepared and tested
by a small team of elementary teachers. We hope they are helpful.
If, as you use the materials, you have questions, we ask that you
get in touch with one of us.
When you study the materials, you will notice that we explained
carefully what we did and our thinking as we worked. Rather than
just provide you with samples of test items and activities which
you could use in measuring your students, learning, we have described
what we did to help you prepare your own test materials. By
following the models given, you will be able to evaluate materials
appropriately in several ways:
* You will be able to really tell what your children have learned
and haven't yet learned.
* You won't miss important learnings just because the procedures
you used didn't ask for them.
* Your evaluations will measure how well your students have learned
the Utah Core Curriculum concepts and the skills you have taught.
* Your evaluations will tell you how well students are mastering
the Utah Intended Learning Outcomes for science.
As you use these materials, notice that first we tried to determine
what the Core really intends that you should teach. Sometimes
the language of the standards and objectives is very general; sometimes
it specifies that students would be able to do things which are
difficult to measure directly; sometimes it gives you no clues as
to what to measure or how to measure it. As you read about our thinking,
we hope you will understand how we resolved these problems. When
you make your own decisions, you may accept ours or come up with
better ones. At least, you will look at some of the same issues
we did as we prepared materials to test students' science learning.
After we interpreted the core statements, we decided what kind of
test item best fit the intent of the core, and at the same time
kept in mind the limited time and the resources elementary teachers
have available to use in measuring students' learning. If you think
of other things that have to do with the skill, or concept, being
studied that aren't in the objectives or the indicators that you
want to include, do so.
We also kept in mind the kinds of measurement tasks that your students
could actually do. For instance, it wouldn't be appropriate
to ask first grade students to read and respond in writing to complex
questions.
Finally, sometimes we commented on the format of the structure
of an item to help you avoid some common pitfalls teachers experience
in preparing test items.
An example of how to work with one objective, 3010-0301,
follows:
SCIENCE LEVEL 1
TOPIC: WATER
STANDARD 3010-03: Students will compare the liquid, solid
and gas states of water.
OBJECTIVE 3010-0301: Compare the physical properties of
ice, liquid water, and water vapor
- Describe in their own words the similarities
and differences between ice, liquid water, and water vapor.
- Describe different ways that water, in all three
states, is present or is used in the natural and designed world.
- Contrast the behavior of ice with the behavior
of water when placed in containers of various shapes.

Analysis of Objective:
To measure how well my students have learned the science concepts
and skills required by The Core Curriculum, I must first determine
what the core standards and objectives mean. After studying the
first objective in the standard, "Compare the physical properties
of ice, liquid water, and water vapor," I have to decide what
"compare the physical properties" means as it applies
to students in my first grade classroom.
A review of the indicators clarified this for me. It is clear that
at this level, the expectation is that students should be able to
' identify and exiplain what the properties are in
simple terms, then be able to alpiply the understanding they
have in different ways, to describe in their own words how
the states are alike and different, to describe ways water
appears in nature and in the designed world, and contrast
the behavior of ice and water when placed in containers of various
shapes. The ability to do these things requires knowledge of content,
verbal skill, and application of some higher level thinking processes.
If the students can identify the properties of ice, liquid water,
and water vapor and compare them by describing in their own words
their likenesses and differences, describe ways each of the states
exist in the natural and designed word, and contrast the behavior
of ice and liquid water when placed in various sized containers,
they will have demonstrated they have accomplished this objective.
This will be my final test for the objective.
Next, I go to the Intended Learning Outcomes. See pages
xi and xii in the Core document. There I find concrete ways to assess
how well students can do many of the following: obtain information,
define, match, explain in own words, distinguish between, demonstrate,
relate concepts and principles, provide instances of, classify,
compare, analyze, and predict.(These verbs from the ILO's help me
know what kinds of items to write and what kinds of experiences
to give students. For instance, describe in their own words,
describe differences and similarities, and contrast
behavior all require some kind of student response in which
students supply their own explanations. Hands on activities with
student/teacher and student/student oral interaction makes this
possible at this level., Physically doing and showing, using real
objectives, verbal explanations, and drawing all provide ways first
grade students can accomplish the objective.
My task now is to decide what to teach, what information about
physical properties of ice, liquid water, and water vapor is appropriate
for students at this grade level. I make certain that the vocabulary
and foundation skills needed are identified and used to solve problems
related to the objective. The verbs used to describe what is required,
as underlined above, include being able to describe in their own
words similarities and differences, to identify and describe ways
water is present, and being able to compare and constrast the behavior
of ice and liquid water in the same situations. The need for familiarity
with several concepts is suggested including the meaning of solid,
liquid, gas, water vapor, evaporation, condensation, freezing, boiling,
and state. Once I have identified the scope of the information needed,
I determine what concepts I will use in teaching and testing. The
objective, what is taught, and what is tested,
should all be directly aligned.
To prepare to teach, I check what is to be learned by reviewing
the standard, the objective, and the indicators. Then I determine
what kind of skill is required at this level to demonstrate that
the objective has been met. These are listed in the Intended Learning
Outcomes (ILOIS) section of the Utah Elementary Core Curriculum
in Science pp.x and xi. Finally, I think backward and ask myself,
"What do students need to be able to do in order to compare
the physical properties of ice, liquid water, and water vapor?"
I ask myself, "What are the tasks?" "What are the
prerequisites (skills and knowledge needed), to be able to do this?"
Then, I make a tentative outline of the content to be taught and
an order for instruction. The following outline was developed following
the steps discussed.
| Task |
To Do This They Should Be Able to: |
Compare the physical properties of ice, liquid water,
and water vapor.
- Describe in their own own words the similarities
and differences between ice, liquid water, and water vapor.
- Describe different ways that water, in all three
states, is present or is used in the natural and designed
world.
- Contrast the behavior of ice with the behavior
of water when placed in containers of various shapes.
|
A. Recognize meanings and identify examples of the
following: solid, liquid, gas, water vapor, evaporation, condensation,
freezing, boiling, state.
B. Describe in their own words similarities and differences
between ice, liquid water, and water vapor by giving examples,
by demonstrating themselves and/or observing experiments done,
and by written or drawn responses.
C. Describe different ways water in all three states
is present, or is used, in the natural and designed world
by identifying examples, listing and comparing what is found,
and by creating written and illustrated pictures, murals,
or booklets giving examples.
D. Demonstrate and explain by using actual objects
and drawings how the behavior of ice and water differ when
placed in containers of various shapes.

In order to be sure I use the means of assessment
(verbs) given in the Core, a chart, such as the one that follows,
can be a useful tool to remind me what verbs I might use (left-hand
side) to prepare test items that will measure each of the concepts
I chose to measure. I put X's to indicate cells for which I should
prepare test items or a test. For example, I could use a multiple
choice item to measure students' ability to distinguish between
liquid and solid water states. This chart can help me insure that
I am testing all of the skills I selected from the ILO'S, and that
I am testing all of the I identified from the objective and its
indicators.

As I plan how to test students on an objective, I remember that
a variety of kinds of items must be prepared. Kinds of items fit
different purposes. My purposes, indicated by the verbs in the left-hand
column should dictate the kinds of items I prepare. For example,
a multiple choice item will not test student's ability to "explain
in own words" skill (c). Nor should a "compare" item
be used to test students' ability to "define" or recall
something. A variety of kinds of items is used because you are testing
a variety of skills. Obviously, any one kind of item cannot assess
all of the kinds of skills listed.
At first grade level, the teacher reads items requiring reading
skill to the students. The students then respond in some way. e.g
by answering orally, by identifying a picture, creating an illustration,
demonstrating with objects, or by a short written response.
Care should be taken to provide for the limited reading and writing
skills of most first grade students. Hands-on experience should
be given the highest priority.
I now begin to write items. I start with some items what will be
used informally in class to deter-mine what my students already
know about the objective. e.g. "Do they already understanding
that by freezing water, ice is made? "Do they know what the
terms "solid" and a "liquid" mean?"
If my goal is to find out how much, or how well, my students have
memorized something, then a short answer item will be all that is
needed. This kind of item is used to test student ability to recall.
For example, If I want to deter-mine if students can remember what
something means (the definition), or tell about what happens in
a given situation (Chart a. 1, and a. 2), I will ask them to do
so. Examples of this kind of item follow:
Example 1:
The teacher asks:
When water is frozen, what is it called?
Student Answer: Ice
Example 2:
The teacher asks:
What can we do to make water evaporate?
Student Answer: Heat it.
The problem with short answer items is that, as a teacher, you
can not always be sure that the students really knows the concept
or skill being discussed. One item for each concept, for example,
will not validly test students' recall.
A safe rule is to test each idea using at least three items.
This reduces the chance that the student will give the correct answer
by guessing or relying on someone else for the
correct response.
Multiple Choice
Multiple choice items require students to select a correct response
from several alternatives. Multiple choice items can be used to
assess a variety of skills. An example of a multiple choice item
that tests recall of content related to identifying a specific water
states follows:
Teacher Asks: Which picture shows water in its solid form?
The student then selects one of the pictures shown.
Other examples of multiple choice items that test ability to identify
and/or compare, and contrast water states follow:
- Example 1.
- The teacher asks:
- Which picture shows water as a vapor?
or
- The teacher shows three pictures; a solid, a liquid, and a vapor,
and has the students select the correct response. One way to provide
for students' lack of writing ability is to use multiple response
techniques, such having students hold up 1,2,3, or A,B,C, cards,
the correct number of counters, crayons, etc. in response to multiple
response questions asked. This can be a "game-like"
activity and give the teacher quickly assessed feedback.
Example 4:
Notice that students are given three alternatives from which to
choose. In most formal assessments first grade students are not
given more than three choices even though four choices would provide
less change for simply guessing answers. At this level, the process
is more important than an arbitrary number.
You can write multiple choice items that measure more than recall
by using such strategies as rephrasing definitions, asking students
to classify, and having students infer logical conclusions.
True/False
True/False items are not included because most trained test item
writers view true-false items as the least valid form of commonly
used item. If your goal is to use tests diagnostically, true-false
items can, too often, reflect students' guessing rather than what
they understand.
Short Student Response (in student's own
words) Essay Type Items
At first grade level, individual and group activities should involve
the students in orally responding to questions and also their using
invented spelling to respond in short written form or dictating
to a scribe (usually the teacher) what they have to say "in
their own words" about content being learned.
If I use the verbs I have listed in the chart, I can prepare several
good kinds of questions. For many reasons, not the least of which
is to add interest and challenge, you should use a variety of question
formats when teaching and testing your students.
When you ask students to explain something in their own words,
students usually are tested beyond the ability to simply recall.
In addition, students learn how to use science processes described
in the ILO's by thinking through problems and responding with logical,
data based, solutions. This is true at primary as well as intermediate
levels. Although most childrens, written language skills are very
limited at this level, using some items that require the student
to respond independently by writing and/or drawing illustrations
is important to their thinking, reading, writing, and science skill
development. Even three or four word invented spelling responses
can be valuable indicators of learning.
An example of this type of question follows:
Comparing/Contrasting and/or Distinguishing
Asking students to make comparisons and/or to distinguish between
two variables, or properties, is an effective way to measure understanding.
This can be a more difficult task than "telling in your own
words." A note of caution, Sometimes being aware that something
is different from something else, doesn't necessarily mean that
a child understands more than what is easily observed on the surface.
For instance, a child may observe that playing in snow is a fun
activity, that because some children don't live where there is snow,
they don't have fun. This would reflect reasoning based on incomplete
evidence.
An example of an appropriate question for a second grade child
would be:
Analaqies
Analogies can be used to build primary students, thinking skills
but should be used with caution and only in informal, "for
fun", game-like situations. Questions that relate concepts,
skills, or processes to one another require students to think at
analysis, synthesis, and evaluation levels in unfamiliar ways. When
analogies are used "just for fun", they can be a valuable
informal way to extend students, thinking.
- Example:
- Teacher reads the analogy. Then asks students to think about
what would be the right answer to this riddle, or puzzle,
or "brain-teaser."
- Analogy: Ice is to cold as Water vapor is to __________.
Answer: warm
These kinds of items are too difficult for most students at at this
level and should be used only for fun, "game-like,, situations
and not for formal assessment.
Performance Test
Performance tests assess what students can do as well as what they
know. With this form of assessment, the teacher can measure understanding
of several concepts at the same time. An advantage of a performance
test is that students usually don't perceive of this activity as
a test, but rather as a fun activity, experiment, or project. There
is some research that shows that girls respond better to these kinds
of activities than to more traditional types of assessment. The
result is that they become more interested in science. Most of the
tasks given in performance tests are open-ended and often have several
appropriate answers or options.
There are some drawbacks to this kind of assessment. Performance
tests take time to plan, arrange, and score. Time, a precious commodity
to elementary school teachers, needs to be carefully considered
when selecting assessment methods. Your priorities will help you
decide. Remember students need practice with a wide variety of tests
and test items. When decisions are made, select the kind of item
that best fits your purpose.
For first grade students, varying lengths of performance tests
might be used to assess progress as student knowledge and experience
develops.
Examples of performance tests, each designed to partially,
not completely, assess the objective to "Compare the
physical properties of ice, liquid water, and water vapor"
follow.
Example 1
Observing Water States
Activity Description
- The students observe water and the physical changes it makes.
Materials Needed
- Water table set up with water
Equipment for heating and boiling water
Ice to observe melting
Procedure
- 1. Provide opportunity for students to play with water at the
water table. Discuss with them what they discover about water.
2. Boil water. Have the students observe what happens. Have them
share what they think happens and where the water goes.
3. Put ice cubes in various places under different conditions.
(See Activity 10 in the Science Resource Book). Have the students
discuss why they think the ice melted faster in one situation
than another.
4. Show changes that occur in the molecular bond when water changes
from a solid to a liquid to a gas.
Have the students stand as close together as they can and be
very still. This represents the molecules in a frozen state.
Have the students spread out a little and move slowly around,
This represents the molecules in a liquid state.
Have the students spread out even more, and allow them a minute
to jump and bounce around quickly to represent water in its
vapor form.
Assessment:
- If each student participates and generate ideas, the objective
will have been met. Informal feedback provided by this kind of
activity gives the teacher valuable information for planning next
steps. The activities described are good for both pre-assessing
backgrounds students already have and building and assessing understandings
gained.
Example 2
All About Water
Activity Description
- The students apply what they know about the physical properties
of water by making illustrated individual water booklets.
Materials Needed
- Paper for making booklets
Pencils, crayons, markers, etc.
Pictures, etc. if desired
Instructions for Making Booklets
- Use three pieces of paper cut in half length wise. Overlap them
so that the top edge is an inch below the previous page. Fold
in half and staple. This makes six page book with pages of different
lengths. See drawing:
Procedure
Scoring Guide
All students should be able to participate at different levels.
Assessment should take into consideration how many responses were
made, how many responses were correct, and the depth of understanding
shown in the response given.
Level 4. Student will have a drawing on each of the six pages
indicating their understanding of the concept.
Level 3. Student will have a drawing on each of the six pages
but the responses will be sketchy or have one incorrect response.
Level 2. Student will have a drawing on each of the six pages
but the responses on 2 or 3 pages is not correct or incomplete.
Level 1. Student tries to respond, but displays show
little understanding of the concepts.
Level 0. Student responses are inappropriate and
incomplete.
Use of performance assessment can be a challenging and exciting
way to involve students in thinking about and applying science processes
and knowledge in their own lives.
