Data Capstones for Alg 1 and Alg 2
When statistics topics are saved for the end of a course, they can be hard to reach. So, Skew The Script is taking a different approach. Each of our daily-format Algebra 1 and Algebra 2 units now includes a data capstone lesson, allowing teachers and students to incorporate statistical thinking into every unit of Algebra 1 and every unit of Algebra 2 that we offer.
Because our Algebra content is organized in contextual units, where students use algebraic models to explore a relevant context over multiple lessons, the data capstone lessons provide students the opportunity to close each unit by analyzing the same context with a statistical approach. This means that…
Statistics learning targets are infused throughout the course, rather than in an unreachable unit at the end of the course.
Statistical analysis is presented in connection with algebraic analysis, rather than as a wholly unrelated set of skills.
Rigorous data analysis becomes a satisfying extension of the unit’s themes, rather than a pointlessly challenging set of exercises.
For a good example, check out our linear systems unit for Algebra 2.
Students start the unit by using systems of equations to model how many years it takes for costly college degrees to “pay off,” compared to the median earnings trajectory of high school graduates. As students proceed through the unit, the contextual questions (e.g. how much does choice of college major matter?) and algebraic models (e.g. systems of inequalities, systems of 3 variables) become more complex. Finally, the unit’s data capstone lesson allows students to use statistical analysis to explore individual variation in earnings, based on career choice. Because students use statistical thinking to extend their exploration of the unit’s key context, statistics becomes a natural extension of algebraic modeling - rather than ‘one more thing’ to learn (that we never have time for).
These new (and, of course, free) lessons are the next step in Skew The Script’s ongoing expansion of algebra-based materials that highlight the relevance of mathematics and make it more accessible to all students. We’re excited to offer them to you and, as always, welcome your feedback as we continue to expand our offerings for your classrooms.
