Program Purpose and Function ✅ input

✅ program functionality

✅ output

✅ describes the overall purpose of the program.

✅ describes what functionality of the program is demonstrated in the video.

✅ describes the input and output of the program demonstrated in the video.		 1 0
Data Abstraction ✅ includes two program code segments:

✅ one that shows how data has been stored in this list (or other collection type).

✅ one that shows the data in this same list being used as part of fulfilling the program’s purpose.

✅ identifies the name of the variable representing the list being used in this response.

✅ describes what the data contained in this list is representing in the program.		 1 1
Managing Complexity ❌ includes a program code segment that shows a list being used to manage complexity in the program.

❌ explains how the named, selected list manages complexity in the program code by explaining why the program code could not be written, or how it would be written differently, without using this list.		 0 0
Procedural Abstraction ✅ includes two program code segments:

✅ one showing a student-developed procedure with at least one parameter that has an effect on the functionality of the procedure.

✅ one showing where the student-developed procedure is being called.

✅ describes what the identified procedure does and how it contributes to the overall functionality of the program.		 1 1
Algorithm Implementation ✅ includes a program code segment of a student-developed algorithm that includes

✅ sequencing

✅ selection

✅ iteration

✅ explains in detailed steps how the identified algorithm works in enough detail that someone else could recreate it.		 1 1
Testing ✅ describes two calls to the selected procedure identified in written response 3c. Each call must pass a different argument(s) that causes a different segment of code in the algorithm to execute.

✅ describes the condition(s) being tested by each call to the procedure.

✅ identifies the result of each call.		 1 1

Reflection

There was one discrepancy between my grading and CollegeBoard’s. I gave the student the point for program purpose and function because they stated that it “provided infomration on a triangle based on inputted side lengths”. I believe that this, along with their additional commentary, did satisfy the requirements for the overall purpose of the program. In order to ensure that I satisfy this requirement, I will throughly explain the purpose of my program and all of its features. I will use technical terminology to clearly convey my knowledge of the topic. A submission may fail to meet this criteria because they fail to discuss the functionality and output of their program appropriately. They were given a 0 out of 1 because there is no partial credit.

I agreed with CollegeBoard’s rubric grade for the 2nd performance task submission. The student clearly meets all criteria required for a 6/6 and had the necessary code and explanations to achieve this score. In my own work, I will ensure that I create mutliple procedures with parameters to manipulate lists. Lists are a large part of the CollegeBoard APCSP requirements, so I’ll add lots of data abstraction methods using them. There is no partial credit awarded, so I will make sure to follow every single requirement exactly. The student who created this CPT did just that.
