1A-AP-10 Develop programs with sequences and simple loops, to express ideas or address a problem.
- Programming is used as a tool to create products that reflect a wide range of interests. Control structures specify the order in which instructions are executed within a program. Sequences are the order of instructions in a program. For example, if dialogue is not sequenced correctly when programming a simple animated story, the story will not make sense. If the commands to program a robot are not in the correct order, the robot will not complete the task desired. Loops allow for the repetition of a sequence of code multiple times. For example, in a program to show the life cycle of a butterfly, a loop could be combined with move commands to allow continual but controlled movement of the character. (source)
1A-AP-12 Develop plans that describe a program’s sequence of events, goals, and expected outcomes.
- Creating a plan for what a program will do clarifies the steps that will be needed to create a program and can be used to check if a program is correct. Students could create a planning document, such as a story map, a storyboard, or a sequential graphic organizer, to illustrate what their program will do. Students at this stage may complete the planning process with help from their teachers. (source)
1A-AP-08 Model daily processes by creating and following algorithms (sets of step-by-step instructions) to complete tasks.
- Composition is the combination of smaller tasks into more complex tasks. Students could create and follow algorithms for making simple foods, brushing their teeth, getting ready for school, participating in clean-up time. (source)
1A-AP-11 Decompose (break down) the steps needed to solve a problem into a precise sequence of instructions.
- Decomposition is the act of breaking down tasks into simpler tasks. Students could break down the steps needed to make a peanut butter and jelly sandwich, to brush their teeth, to draw a shape, to move a character across the screen, or to solve a level of a coding app. (source)
1A-AP-14 Debug (identify and fix) errors in an algorithm or program that includes sequences and simple loops.
- Algorithms or programs may not always work correctly. Students should be able to 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. (source)
1A-AP-15 Using correct terminology, describe steps taken and choices made during the iterative process of program development.
- At this stage, students should be able to talk or write about the goals and expected outcomes of the programs they create and the choices that they made when creating programs. This could be done using coding journals, discussions with a teacher, class presentations, or blogs. (source)
Practices and Concepts
Practice 5: Creating computational artifacts
- "The process of developing computational artifacts embraces both creative expression and the exploration of ideas to create prototypes and solve computational problems. Students create artifacts that are personally relevant or beneficial to their community and beyond. Computational artifacts can be created by combining and modifying existing artifacts or by developing new artifacts. Examples of computational artifacts include programs, simulations, visualizations, digital animations, robotic systems, and apps." (p. 80)
- P5.1. Plan the development of a computational artifact using an iterative process that includes reflection on and modification of the plan, taking into account key features, time and resource constraints, and user expectations. (p. 80)
- P5.2. Create a computational artifact for practical intent, personal expression, or to address a societal issue. (p. 80)
Practice 6: Testing and refining computational artifacts
- "Testing and refinement is the deliberate and iterative process of improving a computational artifact. This process includes debugging (identifying and fixing errors) and comparing actual outcomes to intended outcomes. Students also respond to the changing needs and expectations of end users and improve the performance, reliability, usability, and accessibility of artifacts." (p. 81)
- P6.1. Systematically test computational artifacts by considering all scenarios and using test cases." (p. 81)
- P6.2. Identify and fix errors using a systematic process. (p. 81)
Practice 7: Communicating about computing
- "Communication involves personal expression and exchanging ideas with others. In computer science, students communicate with diverse audiences about the use and effects of computation and the appropriateness of computational choices. Students write clear comments, document their work, and communicate their ideas through multiple forms of media. Clear communication includes using precise language and carefully considering possible audiences." (p. 82)
- P7.2. Describe, justify, and document computational processes and solutions using appropriate terminology consistent with the intended audience and purpose. (p. 82)
- "Control structures specify the order in which instructions are executed within an algorithm or program. In early grades, students learn about sequential execution and simple control structures. As they progress, students expand their understanding to combinations of structures that support complex execution." (p. 91)
- Grade 2 - "Computers follow precise sequences of instructions that automate tasks. Program execution can also be nonsequential by repeating patterns of instructions and using events to initiate instructions." (p. 96)
- "Programs are developed through a design process that is often repeated until the programmer is satisfied with the solution. In early grades, students learn how and why people develop programs. As they progress, students learn about the tradeoffs in program design associated with complex decisions involving user constraints, efficiency, ethics, and testing." (p. 91)
- Grade 2 - "People develop programs collaboratively and for a purpose, such as expressing ideas or addressing problems." (p. 97)
- "Algorithms are designed to be carried out by both humans and computers. In early grades, students learn about age-appropriate algorithms from the real world. As they progress, students learn about the development, combination, and decomposition of algorithms, as well as the evaluation of competing algorithms." (p. 91)
- Grade 2 - People follow and create processes as part of daily life. Many of these processes can be expressed as algorithms that computers can follow." (p. 96)
- "Modularity involves breaking down tasks into simpler tasks and combining simple tasks to create something more complex. In early grades, students learn that algorithms and programs can be designed by breaking tasks into smaller parts and recombining existing solutions. As they progress, students learn about recognizing patterns to make use of general, reusable solutions for commonly occurring scenarios and clearly describing tasks in ways that are widely usable." (p. 91)
- Grade 2 - "Complex tasks can be broken down into simpler instructions, some of which can be broken down even further. Likewise, instructions can be combined to accomplish complex tasks." (p. 97)
- The process of finding and correcting errors (bugs) in programs. (source)
- To find and remove errors (bugs) from a software program. Bugs occur in programs when a line of code or an instruction conflicts with other elements of the code. (source)
- An action or occurrence detected by a program. Events can be user actions, such as clicking a mouse button or pressing a key, or system occurrences, such as running out of memory. Most modern applications, particularly those that run in Macintosh and Windows environments, are said to be event-driven,because they are designed to respond to events. (source)
- The computational concept of one thing causing another thing to happen. (source)
- Any identifiable occurrence that has significance for system hardware or software. User-generated events include keystrokes and mouse clicks; system-generated events include program loading and errors. (source)
- A programming structure that repeats a sequence of instructions as long as a specific condition is true. (source)
- In a loop structure, the program asks a question, and if the answer requires an action, it is performed and the original question is asked again until the answer is such that the action is no longer required. For example, a program written to compute a company’s weekly payroll for each individual employee will begin by computing the wages of one employee and continue performing that action in a loop until there are no more employee wages to be computed, and only then will the program move on to its next action. Each pass through the loop is called an iteration. (source)
- The computational concept of running the same sequence multiple times. (source)
- Refers to processes that occur simultaneously. Printers and other devices are said to be either parallel or serial. Parallel means the device is capable of receiving more than one bit at a time (that is, it receives several bits in parallel). Most modern printers are parallel. (source)
- The computational concept of making things happen at the same time. (source)
- A media object that performs actions on the stage in a Scratch project. (source)
- Like comic strips for a program, storyboards tell a story of what a coding project will do and can be used to plan a project before coding.
