DESIGNING CLASSROOM ENVIRONMENTS
This section proposes
a framework to help guide the design and evaluation of environments that can
optimize learning. Drawing heavily on
the three principles discussed above, it posits four interrelated attributes of
learning environments that need cultivation.
1.
Schools and classrooms must
be learner centered.
Teachers must pay
close attention to the knowledge, skills, and attitudes that learners bring
into the classroom. This incorporates
the preconceptions regarding subject matter already discussed, but it also
includes a broader understanding of the learner.
For example:
• Cultural differences can affect students’
comfort level in working collaboratively versus individually, and they are
reflected in the background knowledge students bring to a new learning
situation (Moll et al., 1993).
• Students’ theories of what it means to be
intelligent can affect their performance.
Research shows that students who think that intelligence is a fixed
entity are more likely to be performance oriented than learning oriented—they
want to look good rather than risk making mistakes while
learning. These
students are especially likely to bail out when tasks become difficult. In
contrast, students who think that intelligence is malleable are more willing to
struggle with challenging tasks; they are more comfortable with risk (Dweck,
1989; Dweck and Legget, 1988).
Teachers in
learner-centered classrooms also pay close attention to the individual progress
of each student and devise tasks that are appropriate .Learner-centered teachers
present students with “just manageable difficulties”—that is, challenging
enough to maintain engagement, but not so difficult As to lead to
discouragement. They must therefore have
an understanding Of their students’ knowledge, skill levels, and interests
(Duckworth, 1987).
2. To provide a knowledge-centered classroom
environment, attention must be given to what is taught (information, subject
matter), why it is taught (understanding), and what competence or mastery looks
like.
As mentioned above, research discussed in the
following chapters shows clearly that expertise involves
well-organized knowledge that supports understanding,
and that learning with understanding is important for the
development of expertise because it makes new learning easier
(i.e.,supports transfer). Learning with
understanding is often harder to accomplish than simply memorizing,
and it takes more time. Many curricula
fail to support learning with understanding because they present
too many disconnected facts in too short a time—the “mile wide,
inch deep” problem. Tests often
reinforce memorizing rather than understanding. The knowledge-centered environment provides
the necessary depth of study, assessing student understanding rather
than factual memory. It
incorporates the teaching of meta-cognitive strategies that
further facilitate future learning.
Knowledge-centered
environments also look beyond engagement as the primary index of successful
teaching (Prawaf et al., 1992).
Students’ interest or engagement in a task is clearly
important. Nevertheless, it does not
guarantee that students will acquire the kinds of knowledge that will support
new learning. There are important
differences between tasks and projects that encourage hands-on
doing and those that encourage doing with understanding; the
knowledge-centered environment emphasizes the latter (Greeno,
1991).
3. Formative assessments—ongoing assessments
designed to make students’ thinking visible to both teachers and students—are
essential. They permit the teacher to
grasp the students’ preconceptions, understand where the students are in the
“developmental corridor” from informal to formal thinking, and design
instruction accordingly. In the assessment-centered classroom environment,
formative assessments help both teachers and students monitor progress.
An
important feature of assessments in these classrooms is that they be learner-friendly: they are not the Friday quiz for which
information is memorized the night before, and for which the student is given a
grade that ranks him or her with respect to classmates. Rather, these assessments should provide
students with opportunities to revise and improve their thinking
(Vye
et al., 1998b), help students see their own progress over the course of weeks
or months, and help teachers identify problems that need to be remedied (problems
that may not be visible without the assessments).
For example,
a high school class studying the principles of democracy might be given a
scenario in which a colony of people have just settled on the moon and must
establish a government.
Proposals from students of the defining features
of such a government, as well as discussion of the problems they foresee in its
establishment, can reveal to both teachers and students areas in which student
thinking is more and less advanced. The
exercise is less a test than an indicator of where inquiry and instruction
should focus.
4. Learning is influenced in fundamental ways by
the context in which it takes place. A
community-centered approach requires the development of norms for the classroom
and school, as well as connections to the outside world, that support core learning
values.
The
norms established in the classroom have strong effects on students’ achievement.
In some schools, the norms could be expressed as “don’t get caught not knowing
something.” Others encourage academic risk-taking and opportunities to make
mistakes, obtain feedback, and revise.
Clearly, if students are to reveal their preconceptions about a subject
matter, their questions, and their progress toward understanding, the norms of
the school must support their doing so. Teachers must attend to designing
classroom activities and helping students organize their work in ways that
promote the kind of intellectual camaraderie and the attitudes toward learning
that build a sense of community.
In such a community, students might help one
another solve problems by building on each other’s knowledge, asking questions
to clarify explanations, and suggesting avenues that would move the group toward
its goal (Brown and Campione, 1994). Both cooperation in problem solving
(Evans, 1989; Newstead and Evans, 1995) and argumentation (Goldman, 1994; Habermas,
1990; Kuhn, 1991; Moshman, 1995a, 1995b; Salmon and Zeitz,1995; Youniss and
Damon, 1992) among students in such an intellectual community enhance cognitive
development. Teachers must be enabled and encouraged to establish a community
of learners among themselves (Lave and Wegner, 1991). These communities can build a sense of
comfort with questioning rather than knowing the answer and can develop a model
of creating new ideas that build on the contributions of individual
members. They can engender a sense of
the excitement of learning that is then transferred to the classroom,
conferring a sense of ownership of
new ideas as they apply to theory and practice.
Students spend only 14 percent of their time
in school.
Not
least, schools need to develop ways to link classroom learning to other aspects
of students’ lives. Engendering parent
support for the core learning principles and parent involvement in the learning
process is of utmost importance (Moll, 1990; 1986a, 1986b). Figure 1.2 shows the percentage of time,
during a calendar year, that students in a large school district spent in
school. If one-third of their time
outside school (not counting sleeping) is spent watching television, then
students apparently spend more hours per year watching television than
attending school.
A
focus only on the hours that students currently spend in school overlooks the
many opportunities for guided learning in other settings.
