new focus on pbl
what is problem-based learning?
• Goals are for students to become better problem solvers
• Four C’s – creativity, communication, collaboration, critical
thinking
• Encourages inquiry and questioning in problem solving

ferocious Grizzly bear charges at them and
they start to run.

what is the right problem-solving question?
• Man 1 asks: Can we outrun the bear?
• Man 2 asks: Can I outrun you?
directly related to ccss practice standards
make sense of problems and persevere in solving them
reason abstractly and quantitatively
construct viable arguments and critique the reasoning of others
use appropriate tools strategically
look for and express regularity in repeated reasoning
look for and make use of structure

what is problem-based learning?
• an approach to curriculum and pedagogy where student
learning and content material are co-constructed by students
and teachers through problems that are:
• both contextually-based and abstract
• discussed
and presented by students in a non-
hierarchical environment
• deliberately
knowledge

my view of project v. problembased
problem-based
• Deliberately scaffolded
whole-problem curricula

project-based
• Preauthentication of
problems for
mathematical experience
• Larger picture projects
with direct instruction
units
• Student Agency stems
from student
presentations of problem
solutions from prior
knowledge and
collaboration
• Emergent authenticity in
mathematical experience
• Student Agency stems

ap bc philosophy
Calculus AB and Calculus BC are primarily concerned with
developing the students’ understanding of the concepts of
calculus and providing experience with its methods and
applications. The courses emphasize a multirepresentational
approach to calculus, with concepts, results, and problems
being expressed graphically, numerically, analytically, and
verbally. The connections among these representations also
are important.
Broad concepts and widely applicable methods are
emphasized. The focus of the courses is neither
manipulation nor memorization of an extensive taxonomy of
functions, curves, theorems, or problem types. Thus,
although facility with manipulation and computational
competence are important outcomes, they are not the core
of these courses

focus on connected curriculum
• scaffolded problems
• decompartmentalized topics
• the connected nature of mathematics
©carmelschettino.org
topics for perusal – look for prior
knowledge triggers and scaffolding
• developing understanding of parametric equations
• exploring more advanced polar graphs
• developing understanding of polar area and arc length
• motivating MacLaurin polynomials
• developing chase problems with differential equations
