Below are sample test items from the
prototype assessment for Biology.
Sample
selected response items:
 |
|
Norma and Jamal are both
affected by color-blindness, a trait that
is sex-linked and recessive. Their
genotypes can be represented by the
following symbols: Norma, XrXr and Jamal XrY. When their
daughter Jessica grew up, she married a
man named Miguel who was not color blind,
and they had several sons and daughters.
Which of theses statements best
describes Jessica and Miguel's children?
All of their sons
are color-blind.
All of their
daughters are color-blind.
Both their sons
and daughters are color blind.
Neither their
sons nor their daughters are
color-blind.

As
this question suggests, multiple choice
or selected responses on the high school
assessments will not be simply a matter
of choosing a correct response. In this
case, students must apply their knowledge
of key facts, concepts, and
generalizations in science to the
evaluation of potential answers. They
should have instructional experiences
responding to these forms of critical
thinking selected response questions in a
variety of science contexts. These forms
of questions require students to apply
both deductive and inductive reasoning
processes. Their science classrooms,
therefore, should be full of experiences
asking students to draw inferences, make
predictions, identify patterns and
abstractions, and complete comparative
analyses. |
Directions:
The computer-generated graph below shows the results
of an experiment measuring the effect of temperature
on fish growth. Use the graph to answer the follow
question.

If trout and carp were
grown in the same tank, which temperature
would allow at least 50% of the trout and
at least 50% of the carp to reach maximum
size?
15ºC
18ºC
28ºC
35ºC

Implications: |

All
effective science classrooms should
actively integrate the use of data in all
phases of instruction. Students need
ongoing scientific instrumentation
experiences involving data collection,
observation, analysis, and presentation.
These processes should be clearly aligned
with the generation and defense of
scientific hypothesis testing.
Additionally, these science selected
response questions involving data
analysis reinforce the need to train
students in a clear analysis of the
question parameters. In this case,
students must apply their understanding
of data implications and parameters.
Models of such questions should be
integrated into both instructional and
assessment activities in science
classrooms. |

constructed response item: Time limit - 15 minutes

A research team
wants to design an experiment to compare
the effects of different fertilizers on
the growth of grass. Typical lawn
fertilizers contain nitrogen, potassium,
and phosphorus. The sample fertilizers to
be tested are listed below:
Fertilizer 1 -
contains nitrogen and phosphorus only
Fertilizer 2 -
contains nitrogen and potassium only
Describe the steps of a
controlled scientific procedure that the
researchers could use to test the
fertilizers over a period of two weeks.

Again,
this constructed response reinforces the
critical role of scientific
experimentation in the science classroom.
Students must receive ongoing direct
instruction in understanding and applying
the process of scientific experimentation
in a variety of settings. Moreover, they
should have instructional experiences
generating both their own scientific
protocols and hypothetical protocols for
others, as reflected in this question.
Like all of the State High School
Assessments, comparative analysis as a
fundamental thinking process should
receive ongoing emphasis in all science
classrooms. Additionally, as in all of
the other core content areas, science
instruction should integrate writing
experiences throughout a course. Both
short responses and extended responses
(including analyses and summaries of
scientific experiments, current events
related to science, and research) should
be a part of students' science
repertoire.
