Standard Identifier: 6-8.CS.1

Grade Range: 6–8
Concept: Computing Systems
Subconcept: Devices
Practice(s): Fostering an Inclusive Computing Culture, Recognizing and Defining Computational Problems (1.2, 3.3)

Standard:
Design modifications to computing devices in order to improve the ways users interact with the devices.

Descriptive Statement:
Computing devices can extend the abilities of humans, but design considerations are critical to make these devices useful. Students suggest modifications to the design of computing devices and describe how these modifications would improve usabilty. For example, students could create a design for the screen layout of a smartphone that is more usable by people with vision impairments or hand tremors. They might also design how to use the device as a scanner to convert text to speech. Alternatively, students could design modifications for a student ID card reader to increase usability by planning for scanner height, need of scanner device to be connected physically to the computer, robustness of scanner housing, and choice of use of RFID or line of sight scanners. (CA NGSS: MS-ETS1-1)

Standard Identifier: 6-8.IC.23

Grade Range: 6–8
Concept: Impacts of Computing
Subconcept: Safety, Law, & Ethics
Practice(s): Communicating About Computing (7.3)

Standard:
Compare tradeoffs associated with licenses for computational artifacts to balance the protection of the creators' rights and the ability for others to use and modify the artifacts.

Descriptive Statement:
Using and building on the works of others allows people to create meaningful works and fosters innovation. Copyright is an important law that helps protect the rights of creators so they receive credit and get paid for their work. Creative Commons is a kind of copyright that makes it easier for people to copy, share, and build on creative work, as long as they give credit for it. There are different kinds of Creative Commons licenses that allow people to do things such as change, remix, or make money from their work. As creators, students can pick and choose how they want their work to be used, and then create a Creative Commons license that they include in their work. For example, students could create interactive animations to educate others on bullying or protecting the environment. They then select an appropriate license to reflect how they want their program to be used by others (e.g., allow others to use their work and alter it, as long as they do not make a profit from it). Students use established methods to both protect their artifacts and attribute use of protected artifacts.

Standard Identifier: 6-8.IC.24

Grade Range: 6–8
Concept: Impacts of Computing
Subconcept: Safety, Law, & Ethics
Practice(s): Communicating About Computing (7.2)

Standard:
Compare tradeoffs between allowing information to be public and keeping information private and secure.

Descriptive Statement:
While it is valuable to establish, maintain, and strengthen connections between people online, security attacks often start with intentionally or unintentionally providing personal information online. Students identify situations where the value of keeping information public outweighs privacy concerns, and vice versa. They also recognize practices such as phishing and social engineering and explain best practices to defend against them. For example, students could discuss the benefits of artists and designers displaying their work online to reach a broader audience. Students could also compare the tradeoffs of making a shared file accessible to anyone versus restricting it to specific accounts. (CA CCSS for ELA/Literacy SL.6.1, SL.7.1, SL.8.1) Alternatively, students could discuss the benefits and dangers of the increased accessibility of information available on the internet, and then compare this to the advantages and disadvantages of the introduction of the printing press in society. (HSS.7.8.4)

Standard Identifier: 9-12.AP.12

Grade Range: 9–12
Concept: Algorithms & Programming
Subconcept: Algorithms
Practice(s): Developing and Using Abstractions, Creating Computational Artifacts (4.2, 5.1)

Standard:
Design algorithms to solve computational problems using a combination of original and existing algorithms.

Descriptive Statement:
Knowledge of common algorithms improves how people develop software, secure data, and store information. Some algorithms may be easier to implement in a particular programming language, work faster, require less memory to store data, and be applicable in a wider variety of situations than other algorithms. Algorithms used to search and sort data are common in a variety of software applications. For example, students could design an algorithm to calculate and display various sports statistics and use common sorting or mathematical algorithms (e.g., average) in the design of the overall algorithm. Alternatively, students could design an algorithm to implement a game and use existing randomization algorithms to place pieces randomly in starting positions or to control the "roll" of a dice or selection of a "card" from a deck.

Standard Identifier: 9-12.AP.14

Grade Range: 9–12
Concept: Algorithms & Programming
Subconcept: Control
Practice(s): Creating Computational Artifacts (5.2)

Standard:
Justify the selection of specific control structures by identifying tradeoffs associated with implementation, readability, and performance.

Descriptive Statement:
The selection of control structures in a given programming language impacts readability and performance. Readability refers to how clear the program is to other programmers and can be improved through documentation. Control structures at this level may include, for example, conditional statements, loops, event handlers, and recursion. Students justify control structure selection and tradeoffs in the process of creating their own computational artifacts. The discussion of performance is limited to a theoretical understanding of execution time and storage requirements; a quantitative analysis is not expected. For example, students could compare the readability and program performance of iterative and recursive implementations of procedures that calculate the Fibonacci sequence. Alternatively, students could compare the readability and performance tradeoffs of multiple if statements versus a nested if statement.

Standard Identifier: 9-12.AP.15

Grade Range: 9–12
Concept: Algorithms & Programming
Subconcept: Control
Practice(s): Creating Computational Artifacts (5.1, 5.2, 5.3)

Standard:
Iteratively design and develop computational artifacts for practical intent, personal expression, or to address a societal issue by using events to initiate instructions.

Descriptive Statement:
In this context, relevant computational artifacts can include programs, mobile apps, or web apps. Events can be user-initiated, such as a button press, or system-initiated, such as a timer firing. For example, students might create a tool for drawing on a canvas by first implementing a button to set the color of the pen. Alternatively, students might create a game where many events control instructions executed (e.g., when a score climbs above a threshold, a congratulatory sound is played; when a user clicks on an object, the object is loaded into a basket; when a user clicks on an arrow key, the player object is moved around the screen).

Standard Identifier: 9-12.CS.1

Grade Range: 9–12
Concept: Computing Systems
Subconcept: Devices
Practice(s): Developing and Using Abstractions (4.1)

Standard:
Describe ways in which abstractions hide the underlying implementation details of computing systems to simplify user experiences.

Descriptive Statement:
An abstraction is a representation of an idea or phenomenon that hides details irrelevant to the question at hand. Computing systems, both stand alone and embedded in products, are often integrated with other systems to simplify user experiences. For example, students could identify geolocation hardware embedded in a smartphone and describe how this simplifies the users experience since the user does not have to enter her own location on the phone. Alternatively, students might select an embedded device such as a car stereo, identify the types of data (e.g., radio station presets, volume level) and procedures (e.g., increase volume, store/recall saved station, mute) it includes, and explain how the implementation details are hidden from the user.

Standard Identifier: 9-12.IC.28

Grade Range: 9–12
Concept: Impacts of Computing
Subconcept: Safety, Law, & Ethics
Practice(s): Communicating About Computing (7.3)

Standard:
Explain the beneficial and harmful effects that intellectual property laws can have on innovation.

Descriptive Statement:
Laws and ethics govern aspects of computing such as privacy, data, property, information, and identity. Students explain the beneficial and harmful effects of intellectual property laws as they relate to potential innovations and governance. For example, students could explain how patents protect inventions but may limit innovation. Alternatively, students could explain how intellectual property laws requiring that artists be paid for use of their media might limit the choice of songs developers can use in their computational artifacts.

Standard Identifier: 9-12.IC.29

Grade Range: 9–12
Concept: Impacts of Computing
Subconcept: Safety, Law, & Ethics
Practice(s): Communicating About Computing (7.2)

Standard:
Explain the privacy concerns related to the collection and generation of data through automated processes.

Descriptive Statement:
Data can be collected and aggregated across millions of people, even when they are not actively engaging with or physically near the data collection devices. Students recognize automated and non-evident collection of information and the privacy concerns they raise for individuals. For example, students could explain the impact on an individual when a social media site's security settings allows for mining of account information even when the user is not online. Alternatively, students could discuss the impact on individuals of using surveillance video in a store to track customers. Additionally, students could discuss how road traffic can be monitored to change signals in real time to improve road efficiency without drivers being aware and discuss policies for retaining data that identifies drivers' cars and their behaviors.

Standard Identifier: 9-12.IC.30

Grade Range: 9–12
Concept: Impacts of Computing
Subconcept: Safety, Law, & Ethics
Practice(s): Communicating About Computing (7.2)

Standard:
Evaluate the social and economic implications of privacy in the context of safety, law, or ethics.

Descriptive Statement:
Laws govern many aspects of computing, such as privacy, data, property, information, and identity. International differences in laws and ethics have implications for computing. Students make and justify claims about potential and/or actual privacy implications of policies, laws, or ethics and consider the associated tradeoffs, focusing on society and the economy. For example, students could explore the case of companies tracking online shopping behaviors in order to decide which products to target to consumers. Students could evaluate the ethical and legal dilemmas of collecting such data without consumer knowledge in order to profit companies. Alternatively, students could evaluate the implications of net neutrality laws on society's access to information and on the impacts to businesses of varying sizes.
