Get Help Analyzing
Tasks
When planning math lessons it is very
important to consider what type of task the students are doing in order to
ensure that the students learn as much as possible. It has been known for a long time that there are
different levels of inquiry that different lessons and different questions
provide. In math there are four distinct
levels of cognitive demand have been defined.
It is important for teachers to consider what their goal is for their
students in regard to these levels.
Since I have become aware of these levels this year my teaching has
changed. I am much more conscious of
what type of task I am doing on a daily basis.
I am trying to provide opportunities for my students to “do math” much
more than I did before. Here are the
levels and some explanations of when they are used.
Low Level –
·
Memorization
¨
Committing
facts to memory
¨
No
procedures
¨
Have
no connections to concepts or meaning
·
Procedures
without connections
¨
Use
of procedure is called for or is evident
¨
Limited
cognitive demand and what needs to be done is evident
¨
Co
connection to the concept or meaning
¨
Focused
on getting right answers not on the understanding of the math
¨
Requires
no explanation
High Level
–
·
Procedures
with connections
¨
Focus
on the use of procedures to develop deeper levels of understanding
¨
Broad
general procedures that connect to concepts
¨
Usually
are represented many ways (visual diagrams, manipulative, symbols)
¨
Requires
some degree of cognitive effort. Any procedures followed may not be done so
mindlessly.
·
Doing
Math Task
¨
Requires
complex thinking (there is no predictable well rehearsed approach to solving
the task)
¨
Demand
self-monitoring or self-regulation of ones own cognitive process.
¨
Requires
students to use prior learning to solve the task
¨
Requires
students to analyze the task and the task constraint so see if there is a limit
to the solutions.
¨
Requires
considerable cognitive effort and may involve some anxiety to the students
It is
unrealistic to think that every day and every lesson could be at the level of
doing math. It is also imperative that
some lessons are at the highest levels.
Only by having lessons that require higher level thinking skills can a
teacher feel secure that she is preparing her students to be successful in
math. The math standards and the math
assessment for the state of Colorado require students at each grade to have the
ability to “do math”.
This
information comes out of the book Implementing Standards-Based Mathematics
Instruction by Mary Kate Stein, Margaret Schwan Smith, Marjorie A
Henningsen, and Edward A. Silver. There
are great case studies in the book which are designed to help teachers make
important decisions that will greatly affect their lesson planning and
implementation.
