Below is a listing of the teaching strategies and skill outcomes from
the CMT on the left column, and opposite on the right are the particular
parts or “instruments” of the Instrumental Enrichment program
which address those CMT strategies and skills. It is proposed that
this program provides a strong and high-quality method by which
to enable students to acquire these critical outcomes and to succeed
on both the CMT as well as in other applications of mathematics. The
numbering of the items in the CMT left column for mathematics content
matches the numbering system used in the CMT Fourth Generation Handbook.
| C.M.T. Practical Instructional Strategies |
Instrumental Enrichment Strategies |
| Asking Why |
Methodology involves regular teacher questioning about why, in
classroom group dialogues |
| A Language-Rich Classroom |
Methodology centers on discussion |
| Creating Mental Pictures |
Several instruments involve creating mental images before discussing
or drawing |
| Focus on Sense-Making |
Student responses are evaluated regularly by peers and teacher
for how sensible they are in problem-solving scenario’s |
| C.M.T. Content Areas |
Instrumental Enrichment (I.E.) Content |
| Solve Word Problems with Multistep Problems |
All instruments involve multiple-step problems within
each exercise page |
| Determine a reasonable estimate |
I.E. problems are posed and students estimate solutions
before beginning a strategy and finding a solution |
| Describe the strategy |
Students are asked to explicitly describe the steps
used, during the metacognitive discussion after every I.E. episode |
| Time |
An entire I.E. instrument, Temporal Relationships,
deals with all aspects of time (estimation, perception, past-present-future,
sequence, causation of events) |
| Spatial Relationships |
The first instrument, Organization of Dots, deals
with geometric shapes and figures which are similar and different;
students draw data on grids in several instruments; students identify
transformations of shapes in Organization; students classify shapes
in Organization |
| Graphing |
Students work with graphs in Numerical Progressions,
both decoding and encoding data in various tabular forms |
| Draw reasonable conclusions |
Students use summarized data in instruments such as
Categorization to develop and defend conclusions |
| Probability |
Students deal early with probability problems, such
as in chart form in Orientation in Space, Part I |
| Make predictions |
In Numerical Progressions, students make predictions
about patterns that are emerging |
| Patterns |
In several instruments ( Organization of Dots, Categorization,
Numerical Progressions, Temporal Relationships) students must identify
patterns which are present but not immediately obvious |
| Identify rules for patterns |
In several instruments, students must predict rules
that summarize patterns |
| Algebraic Concepts-Use Formula’s |
In Numerical Progressions, students first invent formula’s
from given data, and then apply them to new data |
| Algebraic Concepts-Write expressions |
In several instruments, students encode data into
expressions (Temporal Relationships, Numerical Progressions, Transitive
Relations) |
| Classification |
Three instruments teach the classification - Comparisons,
Categorization, and Syllogisms; emphasis is on numerous criteria
for categorizing different forms of data (numerical, pictorial, geometric,
and verbal) |
| Logical Reasoning |
Strategies related to Logic are explicitly taught
through both Transitive Relations and Syllogisms instruments, representing
data graphically and symbolically |
| Venn Diagrams |
The Syllogisms instrument makes direct use of
Venn Diagrams to show how data sets interact logically |
| Permutations and Combinations |
Permutations and Combinations are involved in an early
instrument, Orientation in Space, Part 1. |
| Applications: Spatial problems |
Two instruments deal explicitly with spatial orientation—Orientation
in Space Part 1, which deals with orientation in personal space and
point-of-view, and Orientation in Space Part 2, which deals with
orientation in geographic space. |
