Part 1: Complete in preparation for consultation with Area Assistant Superintendent.

Describe your idea:

Specifically, we want to combine the Advanced Placement Physics I course with the Advanced

Placement Physics C - Mechanics course for our Math and Science Academy as well as our Engineering

Academy students during their junior year. The AP Physics I curriculum encompasses all but ten of the

learning objectives of the AP Physics C Mechanics course, and those ten Learning Objectives have to do

with the use of calculus to more rigorously investigate the physics concepts involved.

End Result:

These Math and Science Academy students will graduate with at least 5 Advanced Placement Science

courses on their transcript and most will opt for another one or two during their senior year. The

increased rigor and opportunity to graduate with between 5 and 7 AP college credits is one of the

factors that makes the Academies of Pope a more lucrative and enticing choice for our students when

they consider choosing one of the magnet programs offered within the county. Additionally, the

number of possible credits is also a factor that makes the Academies of Pope comparable to the

possibilities that exist in the Block Scheduled schools in the county.

Rationale:

These Math and Science Academy students will already have completed a year of AP Calculus AB and

will be taking AP Calculus BC so the incorporation of the calculus will utilize the mathematics skills they

have already mastered. This combination course will allow the students to gain a full and complete

understanding both conceptually from the Physics I course and mathematically from the Physics C

course.

What data has prompted / guided this idea:

A) Student interviews

Having discussed the Physics C Mechanics course and the AP Physics course differences and

expectations with my former Physics I students now taking Mechanics C, there is a consensus that had

they known the calculus, it would have been not only been easier to learn in in the Physics I course, but

would have improved the course and given them a more complete feeling of mastery, where they now

feel like the lion’s share of Mechanics C is review with the tidbits of calculus scattered throughout when

required.

One of the reasons we started the Math and Science Academy at Pope was to offer the students

in our attendance a viable, attractive, and competitive option to the magnet programs that exist within

the county. The Math and Science Academy students are automatically scheduled to take four AP

science courses; Environmental, Biology, Chemistry and Physics I. This pairing will automatically give

them a fifth AP science credit on their transcript and a fifth opportunity to earn college credit or

advanced standing. Most of the students in the Math and Science Academy will probably take a sixth

AP Science and we expect several to take a seventh, which would rival or beat any of the magnet or

block schedule schools in the area, which was the impetus behind the creation of the Academies at

Pope.

B) Having taught both the AP Physics I and AP Physics C mechanics courses, I know the time

requirements which must be followed to complete each course, and the incorporation of the

calculus in those few objectives where it is mentioned will not significantly impact the conduct

of the course. The additional inquiry and laboratory experiences will give these students a more

in depth and thorough treatment of Mechanics without having to expend two of their 24 credits

to do so.

C) Working with the kids at Pope who would have been the Math and Science Academy had it

existed, and having surveyed them, I am confident that this segment of our population will

thrive under the combination of the AP Physics courses. The AP Physics I course is designed to

be a yearlong course to allow extra time for the laboratory component, and the Mechanics C

course has been taught here in that some format; a year to cover what is basically one semester

of college level material. This will allow more than adequate time to imbed the calculus learning

objectives into the AP Physics I curriculum.

D) The grading for this course will be such that students will receive ½ Credit for AP Physics I and ½

credit for AP Physics C Mechanics each semester for a total of two credits at the completion of

the year. With the overlap of the majority of the learning objectives, the combination of the

courses warrants the double credit opportunity.

Describe how you will monitor and measure the effectiveness of the implementation:

A) In class assessment and monitoring – I track the grades of AP Physics Students from year to year

and compare them to make sure they are relatively consistent. I will also be able to compare

the grades of the Academy students with those of the regular AP Physics I students and see if

they are still on par for the course as well as predicting their success on the AP Exams. I have a

limited comparative numbers for the Physics C students I have taught in the past as well.

B) The most telling measure will be the AP exam scores, and the use of the instructional planning

report produced by the College Board for each exam.

C) Communication and feedback from students during in-class discussion regarding their comfort

with material, pace of the course, and academic/college/career goals.

D) Communication and feedback from students and parents

Part 2: Complete after consultation with Area Assistant Superintendent in preparation for Impact

Evaluation Team and Executive Cabinet review and validation.

Describe Budget Implications:

None

Describe Timeline for Communication and Implementation:

Meet with parents and students upon approval, then maintain updates on my blog, along with

semiannual Open House dates.

Science Practices and Laboratory Requirements

The lab requirements listed below for each course are very similar in that with the creation of the AP

Physics I course, the science practices listed below and referenced the learning objectives above

encompass all the science objectives in the Mechanics C course with a mandate to increase the reliance

upon Inquiry and Guided Inquiry labs and activities to enhance student understanding and insight.

AP Physics C Mechanics AP Physics I These objectives overlay the content objectives, and

are assessed in the context of those objectives.

1. Design experiments

Students should understand the process of designing

experiments, so they can:

a) Describe the purpose of an experiment or a

problem to be investigated.

b) Identify equipment needed and describe how it is

to be used.

c) Draw a diagram or provide a description of an

experimental setup.

d) Describe procedures to be used, including controls

and measurements to be taken.

2. Observe and measure real phenomena

Students should be able to make relevant

observations, and be able to take measurements with

a variety of instruments (cannot be assessed via

paper-and- pencil examinations).

3. Analyze data

Students should understand how to analyze data, so

they can:

a) Display data in graphical or tabular form.

b) Fit lines and curves to data points in graphs.

c) Perform calculations with data.

d) Make extrapolations and interpolations from data

4. Analyze errors

Students should understand measurement and

experimental error, so they can:

a) Identify sources of error and how they propagate.

b) Estimate magnitude and direction of errors.

c) Determine significant digits.

d) Identify ways to reduce error.

5. Communicate results

Students should understand how to summarize and

communicate results, so they can:

a) Draw inferences and conclusions from

experimental data.

b) Suggest ways to improve experiment.

c) Propose questions for further study.

Explanation of Areas that are Specific to Physics C Mechanics

Those learning objectives highlighted in the table above are the 10 specific LO’s that are not

overlapping in these two curricula in that they are the objectives that require the use of calculus. These

Math Science Academy students will have already mastered the actual calculus requirements and these

Objectives will be an application of the calculus to the physics situations.

The AP Physics I course was developed to be an algebra based physics course that is rich in

conceptual development and explanation, with somewhat limited requirement of numerical calculations

to solve problems. While many problems involve calculations, the answers are most often required in

terms of algebraic variables rather than numbers. The AP Physics C Mechanics course also has many

questions that require this sort of answer as well. In fact, I have used many of the available Physics C

Mechanics questions as quiz and test questions in my AP Physics I course by deleting the parts of

questions requiring for calculus and with little or no other modification required.

The use of AP Physics C Mechanics Multiple choice questions on test or for review is also

something that was easily accomplished as they are very similar to the sample items released by the

College Board.

In essence, the AP Physics I course is a very complete and fundamental treatment of all the

areas of Mechanics with a focus on conceptual understanding of situations and relationships.

Combining this with the rigorous mathematical treatment mandated by the AP Physics C mechanics

course will give these Math and Science Academy students a complete understanding of Newtonian

Mechanics both mathematically and conceptually and will give them the advantage of accomplishing

this mastery in only one school year.
