“You can see that everyone here wants to figure out how they got

something right, instead of just getting an A. It’s something you
know that they want to understand how. “

Comparison of Traditional and
Relational Classroom
Traditional
Relational
Lecture, direct-instruction
Student-centered instruction
Separate Knowing*
Connected Knowing*
Dualistic view of truth
Appreciation of multiple views of
truth
Authority in meaning-making lies
in teacher
Perception that meaning-making
is constructed by learning

The Curriculum









Problem-Based
Discourse-Driven
Spiraled and Parallel Topics
Built on Prior Knowledge
Student Construction of New Knowledge
Teacher Facilitation and Scaffolding - Key
Multiple Representations
Assessment Variations
Ownership of New Knowledge via Metacognitive
Journaling
Problem Purposes







reviewing material from past courses
triggering prior knowledge for an upcoming
problem
inspiring construction of new knowledge
introducing new terminology
practicing a new skill
challenging the more able students (differentiated
instruction)
seeing the same new idea from a different
representation
Slope – Multiple Perspectives
The vertices A, B and C are
collinear. Find the
dimension n.
Slope – Multiple Perspectives
An airplane is flying at 36000 feet directly
above Lincoln, Nebraska. A little later the plane
is flying at 28000 feet directly above Des
Moines, Iowa, which is 160 miles from Lincoln.
Assuming a constant rate of descent, predict how
far from Des Moines the airplane will be when it
lands.
Slope – Multiple Perspectives
The diagram at right shows the graph of 3x + 4y =
12. The shaded figure is a square, three of whose
vertices are on the coordinate axes. The fourth
vertex is on the line. Find the lengths of the sides
of the square.
Right Angles – Multiple Perspectives
Let A = (3, 2), B = (1, 5), and P = (x, y). Find xand y-values that make ABP a right angle. Describe
the configuration of all such points P.
Right Angles – Multiple Perspectives
Find coordinates for the vertices of a lattice
rectangle that is three times as long as it is wide
with none of the sides horizontal.
