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.
0 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.
0 0
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.
0 0
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.
0 0
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.

Reflection

For the most part, there were little to no discrepancies with any of my scoring and CollegeBoards. On the 4th student’s work, I thought that the student deserved the point for list data usage. However, because they only used a certain attribute of the list, CollegeBoard deemed it unworthy of recieving a 1 in that category. For my project, I’ll make sure to correctly use and explain the usage of data within any list I create so that I don’t miss this point in the future. I am already showcasing this in my implementation of the Todo API which is viewable at this URL The fourth submission did not meet the Data Abstractions criteria for the mentioned reason. It missed Managing Complexity due to insufficient management; it only had a counter which wasn’t enough for the points. Finally, the testing criteria was not met due to a lack of arguments for the tester function.
