Question

The code selection above is taken from the Color Sleuth activity you just completed. This selection would count as an abstraction on the Create PT, but to earn Row 8 you will need to describe how this abstraction manages complexity. Write response 2d describing the abstraction above. Use the writing prompt and scoring guidelines as a guide.

Answer 1

The abstraction in the code selection simplifies the process of counting colored squares in a chart by encapsulating it within a function and using a coding system to represent each color with a specific value.

Step-by-step explanation:

The abstraction in the given code selection manages complexity by encapsulating the functionality within a single function called 'countColorSquares'.

This function takes in the multi-colored chart and counts the number of blue, yellow, and red squares for all ten attributes in Figure 17.2.

By using a coding system to represent each color with a specific value (+1 for blue, nothing for yellow, -1 for red), the abstraction simplifies the process of counting the squares and makes it easier to manage the complexity of the task.

Answer 2

The abstraction in question is a coding system that simplifies the task of cross-referencing elements within a multi-colored chart. This abstraction, whether in coding, art, or analysis, serves to manage complexity by organizing and interpreting data efficiently.

Step-by-step explanation:

The Create Performance Task (PT) for the AP Computer Science Principles course often requires students to talk about abstractions they have used in their programming projects. In this case, the abstraction is a coding system or method the student developed to simplify a complex problem—like tracking different elements in a multi-colored chart. By creating a system where colors or numbers represent different concepts or categories, the student can easily cross-reference and analyze data or information, reducing the complexity of the task at hand. For instance, in the activity described, using a concept combination table facilitates the generation of multiple design concepts, demonstrating how the student combined previous solutions to create new ideas efficiently.

In the context of visual arts, the discussion about how adjacent colors affect each other and how Seurat applied these principles in his paintings represents an artistic abstraction to manage the complexity of visual perception and enhance artistic expression. Meanwhile, in exercises involving the counting or analysis of colors or attributes, such as the energy resources scoring system and the game at a fair, abstractions serve as a way to systematically evaluate and interpret data.
