Extra lessons are nice, but Math teachers don't have 25 hours of spare classtime to spend on new materials, no matter how good it might be.
That's why Bootstrap is aligned to National and State Standards for Mathematics, covering most Functional and Algebraic standards from Grade 7 through Algebra 2. This alignment makes it possible to integrate Bootstrap into the classroom smoothly, using time you've already planned into your pacing guidelines or scope and sequence plans.
For states using the Common Core, Bootstrap is also a model implementation of Common Core Standards for Mathematical Practice, offering explicit pedgagogical recommendation across all eight practice standards.
Bootstrap also satisfies several of the CSTA (Computer Science Teacher's Association) standards across levels 1 (grades K-6), 2 (grades 6-9), and 3 (grades 9-12); Bootstrap1 (the algebra-oriented first course) covers standards in levels 1 and 2, while Bootstrap2 goes deeper into computer science and covers more standards in levels 2 and 3.

Alignment |
MP.1: Make sense of problems and persevere in solving them | Bootstrap students are confronted with challenging problems, and use a problem-solving methodology known as the Design Recipe to solve them. The recipe teaches critical thinking, asking students to write down what they know and think through each step on their way to a solution. |
MP.2: Reason abstractly and quantitatively | Students focus on mathematical models of program behavior, and use quantitative examples to prove these models correct. |
MP.3: Construct viable arguments and critique the reasoning of others | Teachers engage students in discussion about each step in the Design Recipe, asking them to explain how they move from one step to another. In addition, students are challenged to debug the code of others, not just by identifying programmatic flaws but by also identifying faulty reasoning. In Bootstrap:Data Science, students go even further, writing entire research papers based on their findings and then critiquing their peers' findings as well. |
MP.4: Model with mathematics | When students in Bootstrap:Algebra or Reactive want their characters to move, to stay onscreen or collide with one another, they must first model that behavior mathematically. In Data Science, they construct predictive models using linear regression. And since the programming language is purely algebraic, these models become the programs themselves! |
MP.5: Use appropriate tools strategically | Even programmers know that a computer isn't the perfect tool for every situation. Bootstrap students draw graphical diagrams, write out written examples, and use the computer when the situation calls for it. Bootstrap:Reactive allows students to construct and apply appropriate data structures to suit their needs, and Data Science students learn to use visualizations such a bar and pie-charts strategically. |
MP.6: Attend to precision | Communicating precisely is key, whether you're a mathematician or a professional programmer. In every Bootstrap class, students consider datatypes, select clear function and variable names, and write comments for their code. In Reactive, they construct their own data structures precisely based on their needs, and in Data Science they must precisely validate other people's code and consider everything from sampling error to confounding variables. |
MP.7: Look for and make use of structure | Bootstrap students look closely at worked-out examples before generalizing to a formula, as part of the Design Recipe. When working with the Circles of Evaluation, students consider the structure of arithmetic expressions as functions being composed on one another -- and this structure becomes the basis for their code. |
MP.8: Look for and express regularity in repeated reasoning | By practicing the Design Recipe repeatedly, students begin to discern the connection between multiple representations of functions. They notice patterns in the examples they write and contracts they derive. |

The final project for Bootstrap:Data Science is a research paper written by each student which incorporates text, code, and data visualizations to demonstrate their process of analyzing, transforming, and interpreting data to answer meaningful questions. |
3B-NI-05: Use data analysis tools and techniques to identify patterns in data representing complex systems. |
Bootstrap:Data Science - Units 1-9
Bootstrap:Data Science introduces students to a number of data analysis methods, encouraging them to ask questions of large datasets and then sort, filter, and define functions over data to answer those questions. |
3B-NI-07: Evaluate the ability of models and simulations to test and support the refinement of hypotheses. |
Bootstrap:Data Science - Units 2-9
Bootstrap:Data Science has students examine various issues affecting data collection and analysis, including collection bias, threats to validity, and outliers. Using linear regression methods, students can test and refine their hypotheses about relationships in their dataset. |
3B-AP-14: Construct solutions to problems using student-created components, such as procedures, modules and/or objects. |
Bootstrap:Algebra - Units 5-8
Bootstrap:Reactive - Units 1-5 Bootstrap:Data Science - Units 2-9 Bootstrap:Algebra introduces the core idea of functions as abstractions over repeated computations, and has students document, test, and code multiple functions to create a video game. Bootstrap:Reactive moves into larger programs that get decomposed into sub-problems and helper functions, which are designed, implemented and tested independently. Bootstrap:Data Science introduces the idea of writing functions over tabular data to answer meaningful questions about that data. |
3B-AP-21: Develop and use a series of test cases to verify that a program performs according to its design specifications. |
Bootstrap:Algebra - Units 3-8
Bootstrap:Reactive - Units 1-5 Bootstrap:Data Science - Units 2-9 Design and execution of test cases is emphasized throughout all Bootstrap courses. Students are required to write multiple test cases (including expected answers for each) for each function; our software helps them track which tests are passing and which are failing. |
3B-AP-22: Modify an existing program to add additional functionality and discuss intended and unintended implications (e.g., breaking other functionality). |
Bootstrap:Reactive - Units 3-5
Bootstrap:Data Science - Units 2-9 Bootstrap:Reactive has students walk through an iterative design process for adding and refining elements in their programs based on what things will be changing within their programs. Bootstrap:Data Science has students refine data sets by sorting, filtering, and defining functions over data, as well as thinking critically about the need to remove outliers in their data. |

Practice 1: Fostering an Inclusive Computing Culture | By integrating Computing into standard math classes, Bootstrap allows schools to immediately create an inclusive computing environment. Everyone takes math, which means everyone computes. But in addition to the course settings the curriculum allows, Bootstrap also embeds teamwork, metacognition and group reflection into every step of the programming process - from co-designing a game to thinking about effective co-working strategies, Bootstrap's pedagogy fosters an inclusive culture. |
Practice 2: Collaborating Around Computing | Bootstrap students work on small teams, and must cultivate relationships with other students who possess diverse perspectives, skills and personalities. Students work on problems together, and are given strategies to evaluate and give feedback to one another at each step in the problem-solving process. |
Practice 3: Recognizing and Defining Computational Problems | Bootstrap uses real-world problems throughout the course, as students are constantly engaged in the creation of a meaningful computational artifact (a videogame of their own invention, modeling a physics simulation, or analyzing a rich dataset). Each part of this project requires that students identify problems that can be solved computationally, decompose those problems into sub-problems, and evaluate the limits of their solutions. |
Practice 4: Developing and Using Abstractions | Students develop and use abstractions throughout the course, starting with visual-spatial representations for arithmetic expressions and ending with complex, multi-function programs that define, use and re-use student-generated abstractions. Students define everything from Functions (Bootstrap:Algebra) to Data Structures (Bootstrap:Reactive), and Reactive Simulations (Bootstrap:Physics) to Big Data queries (Bootstrap:Data Science). |
Practice 5: Creating Computational Artifacts | Bootstrap's project-based approach is absed on the creation of computational artifacts. Students write programs to draw flags, make a rocket blast off, trap a butterfly, run a cash register, implement a videogame, answer real questions with data, and model an observed physical phenomenon. The creation of these artifacts is personal, customizable, and based on a rigorous methodology for iterative design and problem solving. |
Practice 6: Testing and Refining Computational Artifacts | Many introductory courses treat testing as a second-class citizen, either asking students to test by running a program and "seeing if it looks right" or by using programming tools that completely lack any framework for automated testing. By contrast, Bootstrap introduces testing early on in each course, and our languages and software enviroments offer rich support for writing tests and developing software based on test feedback. |
Practice 7: Communicating About Computing | Students in our Data Science module must choose a question that matters to them, select a relevant dataset, and answer that question - justifying their choice and answer at every step. Students in our Physics, Data Structures and Algebra courses explain their thinking as well, whether it's about the creation of a piecewise function to handle key events or a data structure to model an interactive program. |
Hardware and Software | Bootstrap:Reactive, Bootstrap:Data Science and Bootstrap:Physics introduce students to sophisticated programming paradigms, in which they must process user input as mediated by the software evironment. This mediation involves the flow of information from multiple sources (keyboards, mice, GPS systems, and internet-connected resources), and students must consider this flow when designing their programs. |
Troubleshooting | All Bootstrap modules embrace Example Driven Design, in which students write test cases for each abstraction they create. This bakes in troubleshooting by design: a student immediately has a mechanism to locate an error, and knows a pedagogical approach for debugging their thinking process. |
Data Collection | Students in Bootstrap:Data Science and Bootstrap:Physics collect data using an array of tools techniques: tapping into existing datasets (e.g. - Spreadsheets) as well as automated or manual sampling using an array of instruments. The choice of sampling mechanism is instruction, as it exposes students to the strengths and weaknesses of a particular approach. Movement-tracking via observation v. changes in a cell phone's GPS coordinates, for example, will influence the amount and quality of the data that is collected. |
Visualization and Transformation | Our Data Science module embraces authentic data science concepts in a lightweight fashion: students must identify, transform, clean and manipulate data sets as they explore a research question of their own design. This involves everything from visualizing to aggregation, and rearrangement to transformation. |
Inference and Models | Bootstrap:Algebra and Bootstrap:Reactive are all build around students' developing a model for a desired (or observed) behavior. Bootstrap:Algebra has students model the process of computation, and Bootstrap:Reactive gives students the ability to model the data behind it. Bootstrap:Physics goes one step farther, having students use these models to predict the behavior of a complex system. In these activities, the tradeoffs between model complexity and model quality become clear. |
Algorithms | Bootstrap students consider many algorithms throughout our material. They are confronted with multiple ways to reach a solution, asked to generalize a algorithms so they can be re-used for other problems, and given opportunities to discuss the tradeoffs between different approaches. |
Variables | Bootstrap introduces variables early on, with students confronting variables and functions almost immediately in Bootstrap:Algebra. These variables can be used to represent Numbers, Strings, Images, Booleans, data structures of infinite complexity, and even remote spreadsheets stored across the internet! Our pedagogy explicitly asks students to come up with meaningful identifiers for every variable they use, and Bootstrap:Reactive allows students to select their own Data Structures. (Note: in a slight deviation from the K12CS standards, Bootstrap uses the mathematical concept of variable. Namely, we do not discuss the notion of "machine storage", since that concept directly undermines the notion of variables in mathematics.) |
Control | Students in all of Bootstrap's modules confront program control, sequences of evaluation, and conditionals. Bootstrap:Reactive, Data Science and Physics add loops and event handlers, to create more complex behavior. |
Modularity | Bootstrap's focus on abstraction works hand in hand with the concept of modularity. Students decompose complex problems into smaller ones, and build abstractions (functions, data structures, etc) to solve them. The abstractions are used to organize code, and can be composed with one another or repurposed to solve more complex problems without having to duplicate code. Students assemble these abstractions to form complex, reactive programs - relying on the modularity of those abstractions to manage complexity. |
Program Development | Our pedagogy is based on a robust process for program development, known as the Design Recipe. This approach has been used for decades at the university level, and mirrors many best practices from industrial contexts. The Design Recipe is an iterative process that involves defining type specifications, communicating those specifications through writing, building example-driven test cases, implementation, and testing. |
