1. Different groups or
tracks have substantially different educational experiences (both
content and method of instruction). The lower groups experience lower
quality instruction.
2. The various kinds of
interventions designed to compensate for the initial disadvantages
brought into school by some children (particularly the poor) decline in
number and variety with successive years of schooling.
3. Disproportionate
placement of students of color and poor students are found in the low
groups.
4. Students in lower groups
have lower self-esteem and lower career goals.
5. The level of the group
in which a child participated most regularly in the primary grades is
highly predictive of track placement later.
6. In general there is a
steady decline in both the variety of teaching methods employed and the
amount of teacher support, feedback, and corrective guidance provided
with progression through the grades. This decline in desirable
pedagogical techniques is greater for the low groups.
7. Research has not
demonstrated that the grouping and differential treatment that
accompanies it have led to gains in student achievement for students in
any ability level.
8. The classification
process is rarely well-defined or consistently carried out. The
placements are often based on standardized test that may not be
appropriate (especially for students with language or cultural
differences) or administrated or used inappropriately. Many decisions
are based on subjective information.
