Performance Task Scoring Submission 4

[Soham360]

Program Purpose and Function

• Video
• [x] input
• [x] program functionality
• [x] output
• Written Response
• [x] describes the overall purpose of the program.
• [x] describes what functionality of the program is demonstrated in the video.
• [x] describes the input and output of the program demonstrated in the video.

Data Abstraction

• Written Response
• [x] includes two program code segments
  • [x] one that shows how data has been stored in this list (or other collection type).
  • [x] one that shows the data in this same list being used as part of fulfilling the program’s purpose.
• [x] 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.

Managing Complexity

• Written Response
• [ ] includes a program code segment that shows a list being used to manage complexity in the program.
• [x] 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

Procedural Abstraction

• Written Response
• [x] includes two program code segments:
  • [x] one showing a student-developed procedure with at least one parameter that has an effect on the functionality of the procedure.
  • [x] one showing where the student-developed procedure is being called.
• [x] describes what the identified procedure does and how it contributes to the overall functionality of the program.

Algorithm Implementation

• Written Response
• [x] includes a program code segment of a student- Implementation developed algorithm that includes
  • [x] sequencing
  • [x] selection
  • [x] iteration
• [x] explains in detailed steps how the identified
• [x] algorithm works in enough detail that someone else could recreate it

Testing

• Written Response
• [x] 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.
• [x] describes the condition(s) being tested by each call to the procedure.
• [x] identifies the result of each call.

Reporting Category	Student Score	College Board Score	Comments
Row 1: Program Purpose and Function	1	1	The student met the requirement because the video shows the program running smoothly and provides information on the program's function, purpose, inputs, and outputs.
Row 2: Data Abstraction	0	0	The student does not meet the requirement because the program code for a list is included. The purpose of the list is described but not its role in the program.
Row 3: Managing Complexity	0	0	The student does not meet the requirement because a list is included, but it is not utilized to simplify the program. An alternative method is demonstrated, which increases the complexity of the program.
Row 4: Procedural Abstraction	1	1	The student met the requirement because the function, along with its parameter, is included, as well as an example of it being used in the program. Information is provided on the function's purpose and how it impacts the program.
Row 5: Algorithm Implementation	1	1	The student met the requirement because the procedure demonstrated involves iteration and selection, and is relevant to the program. It explains the function of the procedure and how to reproduce it.
Row 6: Testing	1	0	The student met the requirement because two calls are discussed, including the conditions being tested in each call and the outcomes of each call.
