Recognizing and Defining Computational Problems (3.1)
Standard:
Describe approaches and rationales for keeping login information private, and for logging off of devices appropriately.
Descriptive Statement:
People use computing technology in ways that can help or hurt themselves and/or others. Harmful behaviors, such as sharing passwords or other private information and leaving public devices logged in should be recognized and avoided. Students keep login information private, log off of devices appropriately, and discuss the importance of these practices. For example, while learning about individual responsibility and citizenship, students could create a "privacy folder" to store login information, and keep this folder in a secure location that is not easily seen and accessed by classmates. Students could discuss the relative benefits and impacts of choosing to store passwords in a folder online versus on paper. They could also describe how using the same login and password across many systems and apps could lead to significant security issues and requires even more vigilance in maintaining security. (HSS K.1) Alternatively, students can write an informational piece regarding the importance of keeping login information private and logging off of public devices. (CA CCSS for ELA/Literacy W.K.2, W.1.2, W.2.2)

Standard:
Model and describe how people connect to other people, places, information and ideas through a network.
Descriptive Statement:
Information is passed between multiple points (nodes) on a network. The Internet is a network that enables people to connect with other people worldwide through many different points of connection. Students model ways that people communicate, find information, or acquire ideas through a network. Students use a network, such as the internet, to access information from multiple locations or devices. For example, students could utilize a cloud-based platform to access shared documents or note-taking applications for group research projects, and then create a model (e.g., flowchart) to illustrate how this network aids collaboration. (CA CCSS for ELA/Literacy W.K.7, W.1.7, W.2.7) Alternatively, students could design devices that use light or sound to aid communication across distances (e.g., light source to send signals, paper cup and string “telephones,” and a pattern of drum beats) and then describe how networks build connections. (CA NGSS: 1-PS4-4)

Standard:
Create patterns to communicate a message.
Descriptive Statement:
Connecting devices to a network or the Internet provides great benefit, but care must be taken to protect devices and information from unauthorized access. Messages can be protected by using secret languages or codes. Patterns help to ensure that the intended recipient can decode the message. Students create a pattern that can be decoded and translated into a message. For example, students could use a table to associate each text character with a number. Then, they could select a combination of text characters and use mathematical functions (e.g., simple arithmetic operations) to transform the numbers associated with the characters into a secret message. Using inverse functions, a peer could translate the secret message back into its original form. (CA CCSS for Mathematics 2.OA.A.1, 2.OA.B.2) Alternatively, students could use icons or invented symbols to represent patterns of beat, rhythm, or pitch to decode a musical phrase. (VAPA Music K.1.1, 1.1.1, 2.1.1, 2.2.2)

Algorithms
Practice(s):
Recognizing and Defining Computational Problems, Testing and Refining Computational Artifacts (3.3, 6.3)
Standard:
Compare and refine multiple algorithms for the same task and determine which is the most appropriate.
Descriptive Statement:
Different algorithms can achieve the same result, though sometimes one algorithm might be more appropriate for a specific solution. Students examine different ways to solve the same task and decide which would be the better solution for the specific scenario. For example, students could use a map and create multiple algorithms to model the early land and sea routes to and from European settlements in California. They could then compare and refine their algorithms to reflect faster travel times, shorter distances, or avoid specific characteristics, such as mountains, deserts, ocean currents, and wind patterns. (HSS.4.2.2) Alternatively, students could identify multiple algorithms for decomposing a fraction into a sum of fractions with the same denominator and record each decomposition with an equation (e.g., 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8). Students could then select the most efficient algorithm (e.g., fewest number of steps). (CA CCSS for Mathematics 4.NF.3b) Additionally, students could compare algorithms that describe how to get ready for school and modify them for supporting different goals including having time to care for a pet, being able to talk with a friend before classes start, or taking a longer route to school to accompany a younger sibling to their school first. Students could then write an opinion piece, justifying with reasons their selected algorithm is most appropriate. (CA CCSS for ELA/Literacy W.3.1, W.4.1, W.5.1)

Recognizing and Defining Computational Problems (3.2)
Standard:
Decompose problems into smaller, manageable tasks which may themselves be decomposed.
Descriptive Statement:
Decomposition is the act of breaking down tasks into simpler tasks. This manages complexity in the problem solving and program development process. For example, students could create an animation to represent a story they have written. Students write a story and then break it down into different scenes. For each scene, they would select a background, place characters, and program actions in that scene. (CA CCSS for ELA/Literacy W.3.3, W.4.3, W.5.3) Alternatively, students could create a program to allow classmates to present data collected in an experiment. For example, if students collected rain gauge data once per week for 3 months, students could break down the program tasks: 1) ask the user to input 12 weeks' worth of data, 2) process the data (e.g., add the first four entries to calculate the rain amount for month 1, convert to metric system measurements), and 3) direct the creation or resizing of objects (e.g., one rectangular chart bar for each month) to represent the total number of rainfall for that month. (CA NGSS: 3-ETS-1-2) (CA CCSS for Mathematics 3.MD.2)

Developing and Using Abstractions, Creating Computational Artifacts (4.2, 5.3)
Standard:
Create programs by incorporating smaller portions of existing programs, to develop something new or add more advanced features.
Descriptive Statement:
Programs can be broken down into smaller parts, which can be incorporated into new or existing programs. Students incorporate predefined functions into their original designs. At this level, students do not need to understand all of the underlying implementation details of the abstractions that they use. For example, students could use code from a ping pong animation to make a ball bounce in a new basketball game. They could also incorporate code from a single-player basketball game to create a two-player game with slightly different rules. Alternatively, students could remix an animated story and add their own conclusion and/or additional dialogue. (CA CCSS for ELA/Literacy W.3.3.B, W.3.3.D, W.4.3.B, W.4.3.E, W.5.3.B, W.5.3.E) Additionally, when creating a game that occurs on the moon or planets, students could incorporate and modify code that simulates gravity on Earth. They could modify the strength of the gravitational force based on the mass of the planet or moon. (CA NGSS: 5-PS2-1)

Testing and Refining Computational Artifacts (6.2)
Standard:
Test and debug a program or algorithm to ensure it accomplishes the intended task.
Descriptive Statement:
Programs do not always run properly. Students need to understand how to test and make necessary corrections to their programs to ensure they run properly. Students successfully identify and fix errors in (debug) their programs and programs created by others. Debugging strategies at this level may include testing to determine the first place the solution is in error and fixing accordingly, leaving "breadcrumbs" in a program, and soliciting assistance from peers and online resources. For example, when students are developing a program to control the movement of a robot in a confined space, students test various inputs that control movement of the robot to make sure it behaves as intended (e.g., if an input would cause the robot to move past a wall of the confined space, it should not move at all). (CA NGSS: 3-5-ETS1-3) Additionally, students could test and debug an algorithm by tracing the inputs and outputs on a whiteboard. When noticing "bugs" (errors), students could identify what was supposed to happen and step through the algorithm to locate and then correct the error.

Collaborating Around Computing (2.2)
Standard:
Perform different roles when collaborating with peers during the design, implementation, and review stages of program development.
Descriptive Statement:
Collaborative computing is the process of creating computational artifacts by working in pairs or on teams. It involves asking for the contributions and feedback of others. Effective collaboration can often lead to better outcomes than working independently. With teacher guidance, students take turns in different roles during program development, such as driver, navigator, notetaker, facilitator, and debugger, as they design and implement their program. For example, while taking on different roles during program development, students could create and maintain a journal about their experiences working collaboratively.

Standard:
Demonstrate how computer hardware and software work together as a system to accomplish tasks.
Descriptive Statement:
Hardware and software are both needed to accomplish tasks with a computing device. Students create a model to illustrate ways in which hardware and software work as a system. Students could draw a model on paper or in a drawing program, program an animation to demonstrate it, or demonstrate it by acting this out in some way. At this level, a model should only include the basic elements of a computer system, such as input, output, processor, sensors, and storage. For example, students could create a diagram or flow chart to indicate how a keyboard, desktop computer, monitor, and word processing software interact with each other. The keyboard (hardware) detects a key press, which the operating system and word processing application (software) displays as a new character that has been inserted into the document and is visible through the monitor (hardware). Students could also create a model by acting out the interactions of these different hardware and software components. Alternatively, when describing that animals and people receive different types of information through their senses, process the information in their brain, and respond to the information in different ways, students could compare this to the interaction of how the information traveling through a computer from mouse to processor are similar to signals sent through the nervous system telling our brain about the world around us to prompt responses.

Standard:
Determine potential solutions to solve simple hardware and software problems using common troubleshooting strategies.
Descriptive Statement:
Although computing systems vary, common troubleshooting strategies can be used across many different systems. Students use troubleshooting strategies to identify problems that could include a device not responding, lacking power, lacking a network connection, an app crashing, not playing sounds, or password entry not working. Students use and develop various solutions to address these problems. Solutions may include rebooting the device, checking for power, checking network availability, opening and closing an app, making sure speakers are turned on or headphones are plugged in, and making sure that the caps lock key is not on. For example, students could prepare for and participate in a collaborative discussion in which they identify and list computing system problems and then describe common successful fixes. (CA CCSS for ELA/Literacy SL.3.1, SL.4.1, SL.5.1) Alternatively, students could write informative/explanatory texts, create a poster, or use another medium of communication to examine common troubleshooting strategies and convey these ideas and information clearly.
