Learning
|
Warm-Up Drill Questions
-Formative
|
Formative assessment questions (usually
multiple choice) posted on a PowerPoint slide. Answers to the questions were
discussed after students had some time to write their individual answers.
|
Many outcomes, depending on what was learned
the previous day(s). An example of a drill question was:
“The characteristics listed below can be
used to describe some molecules.
1. inorganic
2. supplies energy and fiber
3. component of plant cell walls
4. part of DNA
5. made of nucleotides
Which of these sets of characteristics
describes a carbohydrate?”
The answer was B. 2,3,4
|
Yes! These assessments were entirely
formative in nature. The questions were never graded, rather, the teacher
used them to get the students thinking and determine if they understood the
material from the previous class. If they, as a whole, seemed to do well, the
teacher would move on. If not, the teacher took the time to review the
material and clarify any misconceptions the students had. The questions
therefore served as opportunities for the students to test their knowledge
and the teacher to determine if/how to modify instruction.
|
Student Questioning and Observation
-Formative
|
Informal verbal questions and observations
throughout class to ensure students are engaged and learning.
|
Any material being learned at the time. For
example, one question asked frequently during the first unit of the course
was “what are the independent and dependent variables of this experiment?”
|
Yes! These questions and observations were
entirely formative in nature. Students can become disengaged if they do the
same thing for a long time, and some students are shy and unwilling to
participate. Therefore, the teacher would break up the PowerPoint or video
lectures with questions, walk around the room and ask questions to individual
students or groups of students, and make observations regarding student
learning that can be used to improve his teaching. If there was something
many students didn’t understand, the instructor could elaborate.
|
Kahoot Quizzes
-Formative
|
Short quizzes in which students participated
via smartphones or desktop computers in the classroom. Questions were mostly
multiple choice or true/false, and had a time limit of 15 seconds. After each
question, the class is provided with a breakdown of how many students
selected each possible response.
|
Multiple topics. The teacher used Kahoot
quizzes for membrane transport (hypo/hyper/isotonic solutions, osmosis vs.
diffusion, active vs. passive transport, etc.), mitosis and meiosis (diploid
vs. haploid, names and descriptions of the phases, etc.), and different cell
types (eukaryotic cells vs. prokaryotic cells and the cell parts found in
each type) among other topics.
|
Yes! Kahoot quizzes were entirely formative
in nature. These quizzes were not graded, but the teacher took the time to
stop the quiz and discuss a topic if the students struggled with it. For
example, many students incorrectly answered a question that asked what would happen
to a cell placed in a particular solution, given the molarities of the
intracellular fluid and extracellular fluid. Students didn’t quite grasp that
water moves from low molarity to high molarity, while salts move from high
molarity to low molarity, so the teacher addressed this difference between
solute and solvent by drawing images on the whiteboard and explaining the
mathematical formulas. Such quizzes inform the teacher how well students have
learned thus far, so that adjustments can be made to improve learning.
|
In-class packet: DNA and Mutations Webquest
-Mostly formative
|
In-class formative assessment packet in
which students were required to go to a website in groups, watch the required
videos, read the required readings, fill in the blanks of their notes, and
respond to questions. Some of the questions were answered via computer to
advance the activity, while others were completed on the corresponding
worksheet and turned in for a grade.
|
Different types of DNA mutations, including
deletions, insertions, substitutions, and frameshift mutations. Knowledge of
specific diseases caused by mutations, including sickle cell anemia and
hemophilia.
|
Yes! This assessment was mostly formative in
nature, as it was used to teach the students about DNA mutations and provide
instant feedback as they responded to questions. Students used the online
activities to learn the material for the first time and take notes. In other
words, this more engaging assessment replaced the lecture that would
traditionally be used to introduce the material. Some of the questions they
answered, however, were turned in for a grade, but it was a relatively
low-stakes assignment. This activity was therefore a discovery based lab that
utilized computers to have students engage in material that would otherwise
be inaccessible in a normal high school classroom, such as sickle blood cells
and their DNA.
|
Worksheet: Protein Synthesis and Mutations
-Formative
|
In-class formative assessment worksheet
students could complete individually or in groups. Students were given an
original DNA sequence (TACGATACT) and a key for converting mRNA codons to
amino acids. They were asked to write the complementary DNA sequence, mRNA
sequence, tRNA sequence, and amino acid sequence, as well as list the name of
each step and where it occurs in a cell. Then, they were asked to repeat the
process if one base was changed, and answer some follow-up questions.
|
Knowledge of the components of gene
expression, including transcription and translation: complementary base pairs
(A-T and C-G in DNA, and A-U in RNA), where the processes occur, and how a
mutation may affect protein structure.
|
Yes! This worksheet was the first chance for
the students to try the full process of gene expression from start to finish,
and the teacher pointed out a few learning tips towards the end. For example,
he pointed out that because the DNA coding
strand and mRNA codon sequence
(notice the letter “C”) are both complementary to the DNA template strand,
the two should have the same base sequence, with U’s in RNA and T’s in DNA.
Similarly, the DNA template strand
and tRNA strand (notice the letter
“T”) would have the same sequence. This tip improved student understanding of
the whole process. The worksheet was formative in nature, as it was not
turned in for a grade, and the class discussed the answers to improve student
understanding of gene expression.
|
Classwork/Homework Packet: Making Karyotypes
-Summative
|
A summative packet in which students were
required to use scissors to cut chromosomes out of a “cell” and assemble them
like they would if they were a scientist making a karyotype. They then
compared their karyotypes to other images given, and were required to
identify if their karyotype was normal, or if there was a genetic disorder
present.
|
Knowledge of karyotyping, including:
chromosomes are ordered by size, there should be 23 pairs of chromosomes, and
how to identify certain genetic disorders, such as Turner Syndrome (female
with one X chromosome) and Trisomy 21 / Down syndrome (three 21st
chromosomes).
|
No formative component. The first part of
the assignment was treated like a performance assessment, as the students
were required to create and turn in a karyotype. The follow-up questions were
answered and graded as summative constructed-response questions. Because the
assessment was used to evaluate student understanding of karyotyping and not
improve instruction or learning, this assessment would be considered
summative rather than formative.
|
Lab Assignment:
Testing for Macromolecules
-Summative
|
In-class summative assessment. Students were
given a sample of a McDonald’s Happy Meal that was blended together. They
were required to test known solutions using the Benedict’s test for
monosaccharides, Lugol’s test for polysaccharides, Biuret test for proteins,
and the Sudan III test for lipids. After, students tested the blended meal to
determine which macromolecules were present. Finally, students completed a
worksheet with post-lab questions.
|
Knowledge of the different macromolecules
and how to test for their presence, as well as proper lab procedure,
including wearing goggles, properly heating substances, cleaning test-tubes
between trials, and drawing conclusions from tests conducted on known and
unknown substances
|
Very little formative component. This
assessment was primarily summative in nature, as it was given towards the end
of the unit on macromolecules. Students already knew the characteristics of
the different macromolecules and how to test for them in solution, so this assignment
gave them the opportunity to put their knowledge and skills to the test as a
real scientist would. It was not used to improve teaching or learning in a
significant way, and the grade assigned to this lab activity was weighted
more heavily than the others listed.
|
Lab Assignment: Dialysis Tubing
-Formative
|
In-class formative assessment. Students
set-up two dialysis experiments. In the first, starch and water were added to
an enclosed dialysis tube and suspended in a beaker of plain water. In the second,
glucose and water were added to an enclosed dialysis tube and suspended in a
beaker of water. Students took the mass of the bags before suspension in
water and after 24 hours, then conducted tests in the beaker of water for the
presence of monosaccharides and polysaccharides. Students completed a
worksheet after the experiment.
|
Knowledge of macromolecules and membrane
properties. For example, students were supposed to conclude that because the
bag with glucose decreased in mass, and glucose was detected in the beaker of
water, that glucose could pass through the membrane (bag) and diffused into
the hypotonic solution that surrounded it. Starch is too large, causing water
to move into the bag via osmosis and increase the mass of the bag.
|
Yes! This lab was used before membrane
transport was covered in detail. Students were introduced to the plasma
membrane before the lab in basic detail, but this lab was used as a teaching
opportunity that allowed students to see firsthand how osmosis and diffusion work
together to maintain homeostasis (osmolarity), and how smaller molecules more
readily move through the membrane. A more detailed discussion of membrane
transport and a Kahoot quiz followed the lab activity, for additional
learning. Post-lab questions were turned in for a small grade, but the
assessment should still be considered formative in nature.
|
Lab Assignment: Introduction to Microscopes
and Prokaryotic vs. Eukaryotic cells
-Formative
|
Students were introduced to the basics of
microscopes, and used a slide with the letter “e” on it to learn how to
operate a microscope. This was followed by an activity that allowed students
to look at and draw different types of cells, including animal cells, plant
cells, protist cells, and bacteria cells. Their drawings were turned in and
graded mostly for completion.
|
Proper lab technique regarding use of
microscopes (focus at each magnification before zooming in, don’t use coarse
adjustment knob at high power, etc.). Knowledge of the differences between
types of cells, including plant cells (box-shaped, chloroplasts, cell walls,
large central vacuoles), animal cells (round-shape, lack chloroplasts and
cell walls), protist cells, and bacteria cells (lack membranous organelles
and nuclei, have cell walls, often have cilia or flagella).
|
Yes! After being introduced to the basics of
microscopes, students could see the principles in action. For example, they
would notice how the image gets larger and the field of vision gets smaller
when the magnification is increased, and that the “e” would be flipped
upside-down and backwards based on how the light-rays are magnified. Students
were also able to see with their own eyes the key differences between the
main cell types discussed, and were shown a Venn diagram comparing the cell
types afterwards. The lab had a worksheet that was turned in for a grade, but
this assessment was mainly used to improve learning by showing students real
examples of principles of microscopy and differences in cell types.
|
Worksheet:
Cell Membrane Coloring Worksheet
-Formative
|
In-class formative assessment worksheet.
Students were asked to identify the parts of the cell membrane on an image,
color code each part according to a key, and match the structure name to the
appropriate function.
|
Knowledge of parts of a cell membrane and
their functions, including: phospholipid bilayer, integral protein, fatty
acid tails, phosphate heads, peripheral protein, cholesterol, glycoproteins,
and glycolipids.
|
Yes! The teacher checked the worksheets
in-class and addressed the class for misconceptions, such as the difference
between integral and peripheral proteins, which many students confused. The
worksheet was ultimately turned in for a grade, but the primary purpose of
the assessment was to improve student understanding of the cell membrane,
making it formative in nature.
|
Unit Test- Skills and Processes and
Biological Molecules
-Summative
|
Summative written assessment composed
entirely of multiple choice questions administered on paper via scantron. Students
were given an hour to answer the fifty-question test individually.
|
Knowledge of basics of science, including
independent vs. dependent variables, control groups, lab safety rules,
scientific notation, the scientific method, etc.
Knowledge of basic biological molecules
including water, vitamins, proteins and enzymes, amino acids, lipids, nucleic
acids, carbohydrates, etc.
|
No formative component; completely summative
in nature. Meant to measure learning, but not necessarily improve learning or
teaching. Rather, this assessment was used to evaluate student learning at
the end of the first unit of the course.
|
Biology HSA
-Summative standardized test
|
Written assessment containing multiple
choice, true/false, and matching questions.
|
All knowledge students are meant to acquire
in Biology I, including basics of science, molecular biology, cell biology,
heredity and evolution, organismal diversity, and ecology.
|
No formative component at all. This
assessment is a state-wide test used to evaluate students, but it is given at
the end of the course. Teachers may be able to use the results to adjust
their teaching for future classes, but they are unable to use the results to
improve the learning of the students who took the test, making it summative. The
Biology HSA is also considered standardized because the same assessment is
given to every student in the state under the same conditions. Furthermore,
students receive norm-referenced data weeks after taking the exam.
|
Interesting
things I noticed:
-Most of the
assessments were turned in for a grade, but were primarily formative in nature.
The worksheets and lab activities, for example, provided students with
opportunities to test the knowledge they learned in class before taking a more
high-stakes summative assessment.
-I noticed
more “informal” assessments than I perhaps would have before I took this
course. I remember most of my assessments in school being worksheets, quizzes,
and tests. In my field experience, however, I noticed drill questions, Kahoot
quizzes, and some worksheets that were never graded. They were instead used to
improve learning.
-I didn’t
notice any examples of affective assessment. Perhaps the teacher could
incorporate affective assessment questions into Kahoot quizzes to evaluate
student values and beliefs.
-I also
didn’t notice many performance assessments, presentations, or projects. While
this may be due to the limited time I’ve spent in the classroom, these
assessments are crucial for assessing skill development and knowledge
application.
-Lab
activities were used in this class far more than any of the courses I took in
high school. These were used both before primary instruction, as a sort of
inquiry-based engaging activity, and after primary instruction, to allow
students to test their knowledge.
