Tharp, R. G. & Gallimore, R. (1988). The redefinition of teaching and schooling (Chapter 1, pp. 13-26), A theory of teaching as assisted performance (Chapter 2, pp. 27-43) in Rousing minds to life: Teaching, learning and schooling in social context. New York. Cambridge University
Thesis: Teaching must be redefined as assisted performance. Teaching consists
in assisting performance. Teaching is occurring when performance is achieved with assistance.
Traditional "teaching": lecturing, explaining, and asking students questions
Duffy and his associates (Duffy, 1981; Duffy, Lanier, & Roehler,
1980) summarized the work on teacher effectiveness and drew two conclusions:
(a) The most effective teachers of basic skills generate the greatest
opportunity to learn. (b) Such teachers are technical managers of
instructional materials and activities rather than theory-driven and
reflective decision makers.
Teaching as assistance
- Of what does this "other" kind of teaching consist? For one thing, it
clearly involves subject-matter competence. To do more than manage
activities and allow students to learn on their own, teachers must command
the knowledge and skills they seek to impart (Shulman, 1986). The point of
teaching is to impart knowledge and the capacity to process that knowledge
- But knowing the subject matter is not sufficient for teachers. Pedagogical expertise is also required (Berliner, 1986), of which there are many kinds.
Rousing minds to life
- Until internalization occurs, performance must be assisted.
- Assisted performance identifies a fundamental process of development and learning.
- Students cannot be left to learn on their own; teachers cannot be content
to provide opportunities to learn and then assess outcomes; recitation
must be deemphasized; responsive, assisting interactions must become
commonplace in the classroom. Minds must be roused to life.
- "If seek to promote the quality of teaching,
reforms should also provide [teachers] some means to improve"
- How are we to achieve in schools the conditions that will make them
places for teachers as well as students? The solution will involve others
besides teachers.
In one view, the definitions of teaching and teachers are straightforward
and readily mastered: Teaching can be reduced to a few days of standard
in-service training that teachers can implement on their own. Such teaching
can be assessed with an observation form and teachers can be
assessed with a test. The results of teaching can be checked by standardized
achievement tests.
(p.24)
In an other view. teaching is a complex, humane activity at which a
teacher can grow steadily more proficient over the years by means of disciplined
curiosity, continuous training, and skillful assistance. Teachers
can be supported and evaluated by persons - including principals - who
join with them in mastering and advancing the craft. In this view, one
influences teachers primarily by organizing the support and recognition
that will permit them to realize the higher motives of service that bring
them to teaching.
Supervision should be defined - particularly in an institution devoted to
teaching - as assisting performance in precisely the terms we used to
define teaching.
"In collaborative settings, teachers acquire and develop better skills through their
collective analysis, evaluation, and experimentation with new teaching strategies." (Rosenholtz, 1986, p. 518)
Chapter 2 - A theory of teaching as assisted performance
Assisted performance defines what a child can do with help, with the support
of the environment, of others, and of the self. For Vygotsky, the contrast
between assisted performance and unassisted performance identified
the fundamental nexus of development and learning that he called
the zone of proximal development (ZPD).
Vygotsky's work principally discusses children, but identical processes
can be seen operating in the learning adult.
T & G's general definition of teaching: Teaching
consists in assisting performance through the ZPD. Teaching can be said
to occur when assistance is offered at points in the ZPD at which performance
requires assistance.
The four stages of the ZPD:
Stage I: Where performance is assisted by more capable others
Stage II: Where performance is assisted by the self
Stage III: Where performance is developed, automatize, and "fossilized"
Stage IV: Where de-automatization of performance leads to recursion back through the ZPD
Responsive assistance
In the transition from other-assistance to self-assistance (and automatization)
there are variations in the means and patterns of adult assistance
to the child. At the earlier phases, assistance may be frequent and elaborate.
Later, it occurs less often and is truncated . Adult assistance is contingent
on and responsive to the child's level of performance.
If the truncated guidance fails, the adult may add additional hints, testing
to find that minimum level of help the child needs to proceed. This
continual adjustment of the level and amount of help is responsive to the
child's level of performance and perceived need.
However, patient, contingent, responsive, and accurately tuned adult
assistance does not always occur. A major variable here is the nature of
the task or performance.
"Assistance" offered at too high a level will disrupt child performance and is not effective teaching. Once independent skill has been achieved, "assistance" becomes "interference."
That's why T & G say teaching occurs when assistance is offered at points in the ZPD at which performance
requires assistance.
As common as assisted performance is in the interactions of parents and
children, it is uncommon in those of teachers and students. Why?
First, to provide assistance in the ZPD,
the assistor must be in close touch with the learner's relationship to the
task. Sensitive and accurate assistance that challenges but does not dismay
the learner cannot be achieved in the absence of information.
Second, while most parents do not need to be trained to assist performance, most teachers do. Teachers need a more elaborate set of skills in assistance, and they need to be more conscious of
their application. Teachers need to learn good pedagogical practices.
