Grade Range:
K–2
Concept:
Algorithms & Programming
Subconcept:
Program Development
Practice(s):
Testing and Refining Computational Artifacts (6.2)
Standard:
Debug errors in an algorithm or program that includes sequences and simple loops.
Descriptive Statement:
Algorithms or programs may not always work correctly. Students use various strategies, such as changing the sequence of the steps, following the algorithm in a step-by-step manner, or trial and error to fix problems in algorithms and programs. For example, when given images placed in a random order, students could give step-by-step commands to direct a robot, or a student playing a robot, to navigate to the images in the correct sequence. Examples of images include storyboard cards from a familiar story (CA CCSS for ELA/Literacy RL.K.2, RL.1.2, RL.2.2) and locations of the sun at different times of the day (CA NGSS: 1-ESS1-1). Alternatively, students could "program" the teacher or another classmate by giving precise instructions to make a peanut butter and jelly sandwich or navigate around the classroom. When the teacher or classmate doesn't respond as intended, students correct their commands. Additionally, students could receive a partially completed soundboard program that has a variety of animals programmed to play a corresponding sound when the user touches them. Students correct any sounds that don't match the animal (e.g., if the cat moos, students change the moo sound to meow).

Standard:
Use an iterative process to plan and develop a program by considering the perspectives and preferences of others.
Descriptive Statement:
Planning is an important part of the iterative process of program development. Students gain a basic understanding of the importance and process of planning before beginning to write code for a program. They plan the development of a program by outlining key features, time and resource constraints, and user expectations. Students should document the plan as, for example, a storyboard, flowchart, pseudocode, or story map. For example, students could collaborate with a partner to plan and develop a program that graphs a function. They could iteratively modify the program based on feedback from diverse users, such as students who are color blind and may have trouble differentiating lines on a graph based on the color. (CA CCSS for Mathematics 5.G.1, 5.G.2) Alternatively, students could plan as a team to develop a program to display experimental data. They could implement the program in stages, generating basic displays first and then soliciting feedback from others on how easy it is to interpret (e.g., are labels clear and readable?, are lines thick enough?, are titles understandable?). Students could iteratively improve their display to make it more readable and to better support the communication of the finding of the experiment. (NGSS.3-5-ETS1-1, 3-5-ETS1-2, 3-5-ETS1-3)

Practice(s):
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.

Recognizing and Defining Computational Problems (3.1)
Standard:
Describe physical and digital security measures for protecting personal information.
Descriptive Statement:
Personal information can be protected physically and digitally. Cybersecurity is the protection from unauthorized use of electronic data, or the measures taken to achieve this. Students identify what personal information is and the reasons for protecting it. Students describe physical and digital approaches for protecting personal information such as using strong passwords and biometric scanners. For example, students could engage in a collaborative discussion orally or in writing regarding topics that relate to personal cybersecurity issues. Discussion topics could be based on current events related to cybersecurity or topics that are applicable to students, such as the necessity of backing up data to guard against loss, how to create strong passwords and the importance of not sharing passwords, or why we should keep operating systems updated and use anti-virus software to protect data and systems. Students could also discuss physical measures that can be used to protect data including biometric scanners, locked doors, and physical backups. (CA CCSS for ELA/Literacy SL.3.1, SL.4.1, SL.5.1)

Fostering an Inclusive Computing Culture, Collaborating Around Computing (1.1, 2.3)
Standard:
Seek and incorporate feedback from team members and users to refine a solution that meets user needs.
Descriptive Statement:
Development teams that employ user-centered design processes create solutions (e.g., programs and devices) that can have a large societal impact (e.g., an app that allows people with speech difficulties to allow a smartphone to clarify their speech). Students begin to seek diverse perspectives throughout the design process to improve their computational artifacts. Considerations of the end-user may include usability, accessibility, age-appropriate content, respectful language, user perspective, pronoun use, or color contrast. For example, if students are designing an app to teach their classmates about recycling, they could first interview or survey their classmates to learn what their classmates already know about recycling and why they do or do not recycle. After building a prototype of the app, the students could then test the app with a sample of their classmates to see if they learned anything from the app and if they had difficulty using the app (e.g., trouble reading or understanding text). After gathering interview data, students could refine the app to meet classmate needs. (CA NGSS: MS-ETS1-4)

Testing and Refining Computational Artifacts (6.1)
Standard:
Systematically test and refine programs using a range of test cases.
Descriptive Statement:
Use cases and test cases are created to evaluate whether programs function as intended. At this level, students develop use cases and test cases with teacher guidance. Testing should become a deliberate process that is more iterative, systematic, and proactive than at lower levels. For example, students test programs by considering potential errors, such as what will happen if a user enters invalid input (e.g., negative numbers and 0 instead of positive numbers). Alternatively, in an interactive program, students could test that the character cannot move off of the screen in any direction, cannot move through walls, and can interact with other characters. They then adjust character behavior as needed.

Standard:
Explain potential security threats and security measures to mitigate threats.
Descriptive Statement:
Cybersecurity is an important field of study and it is valuable for students to understand the need for protecting sensitive data. Students identify multiple methods for protecting data and articulate the value and appropriateness for each method. Students are not expected to implement or explain the implementation of such technologies. For example, students could explain the importance of keeping passwords hidden, setting secure router administrator passwords, erasing a storage device before it is reused, and using firewalls to restrict access to private networks. Alternatively, students could explain the importance of two-factor authentication and HTTPS connections to ensure secure data transmission.

Standard:
Systematically design programs for broad audiences by incorporating feedback from users.
Descriptive Statement:
Programmers use a systematic design and review process to meet the needs of a broad audience. The process includes planning to meet user needs, developing software for broad audiences, testing users from a cross-section of the audience, and refining designs based on feedback. For example, students could create a user satisfaction survey and brainstorm distribution methods to collect feedback about a mobile application. After collecting feedback from a diverse audience, students could incorporate feedback into their product design. Alternatively, while developing an e-textiles project with human touch sensors, students could collect data from peers and identify design changes needed to improve usability by users of different needs.

Testing and Refining Computational Artifacts (6.3)
Standard:
Iteratively evaluate and refine a computational artifact to enhance its performance, reliability, usability, and accessibility.
Descriptive Statement:
Evaluation and refinement of computational artifacts involves measuring, testing, debugging, and responding to the changing needs and expectations of users. Aspects that can be evaluated include correctness, performance, reliability, usability, and accessibility. For example, after witnessing common errors with user input in a computational artifact, students could refine the artifact to validate user input and provide an error message if invalid data is provided. Alternatively, students could observe a robot in a variety of lighting conditions to determine whether the code controlling a light sensor should be modified to make it less sensitive. Additionally, students could also incorporate feedback from a variety of end users to help guide the size and placement of menus and buttons in a user interface.

Standard:
Compare and contrast cryptographic techniques to model the secure transmission of information.
Descriptive Statement:
Cryptography is a technique for transforming information on a computer in such a way that it becomes unreadable by anyone except authorized parties. Cryptography is useful for supporting secure communication of data across networks. Examples of cryptographic methods include hashing, symmetric encryption/decryption (private key), and assymmetric encryption/decryption (public key/private key). Students use software to encode and decode messages using cryptographic methods. Students compare the costs and benefits of using various cryptographic methods. At this level, students are not expected to perform the mathematical calculations associated with encryption and decryption. For example, students could compare and contrast multiple examples of symmetric cryptographic techiques. Alternatively, students could compare and contrast symmetric and asymmetric cryptographic techniques in which they apply for a given scenario.
