
Not just for the Pre-AP, AP or ALPS
classroom.

Teacher’s with students who are identified as
GT must provide differentiation within their
own classroom setting.

Differentiation even for unidentified students
can help maintain classroom management.

Please…
 Don’t put the advanced learner in a position in which
they must tutor others
 Don’t make the differentiation MORE work. It should
be appropriately challenging and different work than
other students who need more support.
 Don’t make a big deal out of the differentiation. The
techniques should be seamless and integrated, just as
all differentiated instruction should.

Please…
 Don’t take grades on mastery above the grade or
course level of student’s enrollment.
 This is the MOST important of all. We want
students to take our classes.

Open ended questions are utilized on every
AP test and account for 50% or more of the
test.
The exam questions are scaffold and
generally start with easier questions that
guide students toward more difficult
questions.
My regular ed. students will never take an AP
class!
A student is assigned the task of determining the mass percent of silver in an alloy of copper and silver by dissolving a sample of the alloy in excess
nitric acid and then precipitating the silver as AgCl. First the student prepares 50. mL of 6 M HNO3 .
(a) The student is provided with a stock solution of 16 M HNO3 , two 100 mL graduated cylinders that can be read to ±1 mL, a 100 mL beaker that
can be read to ±10 mL, safety goggles, rubber gloves, a glass stirring rod, a dropper, and distilled H2O.
(i) Calculate the volume, in mL, of 16 M HNO3 that the student should use for preparing 50. mL of 6 M HNO3 .
(ii) Briefly list the steps of an appropriate and safe procedure for preparing the 50. mL of 6 M HNO3. Only materials selected from those
provided to the student (listed above) may be used.
(iii) Explain why it is not necessary to use a volumetric flask (calibrated to 50.00 mL ±0.05 mL) to perform the dilution.
(iv) During the preparation of the solution, the student accidentally spills about 1 mL of 16 M HNO3 on the bench top. The student finds three
bottles containing liquids sitting near the spill: a bottle of distilled water, a bottle of 5 percent NaHCO3(aq), and a bottle of saturated NaCl(aq).
Which of the liquids is best to use in cleaning up the spill? Justify your choice.
Then the student pours 25 mL of the 6 M HNO3 into a beaker and adds a 0.6489 g sample of the alloy. After the sample completely reacts with the
acid, some saturated NaCl(aq) is added to the beaker, resulting in the formation of an AgCl precipitate. Additional NaCl(aq) is added until no more
precipitate is observed to form. The precipitate is filtered, washed, dried, and weighed to constant mass in a filter crucible. The data are shown in
the table below.
Mass of sample of copper-silver alloy
0.6489 g
Mass of dry filter crucible
28.7210 g
Mass of filter crucible and precipitate (first weighing)
29.3587 g
Mass of filter crucible and precipitate (second weighing)
29.2599 g
Mass of filter crucible and precipitate (third weighing)
29.2598 g
(b) Calculate the number of moles of AgCl precipitate collected.
(c) Calculate the mass percent of silver in the alloy of copper and silver.

Learning contracts are both a teaching strategy and an
assessment tool used to encourage self-directed learning.
They are a negotiation between the student and teacher that
allows for shared responsibility of the planning and learning
experiences.
Through learning plan development students begin to take
responsibility and control over their own learning.
Learning contracts allow students to work at different levels
according to their own knowledge.
Allows students to pace themselves and create their own
assignments to prepare themselves for the assessment.
