Hi all-
There is a glaring difference between the educational
research
and the physics research the I have seen. The educational
exeriments seem
to be generally designed and conducted for the purpose of proving
the
correctness of an educational theory. Physics experiments are
generally
designed and conducted for the purpose of disproving a physical
theory.
That is why there are many experimental physics papers labeled
"Search for
..." (with the implication that the search was unsuccessful) and
the
result being an upper or lower bound on the value of some
conjectured
quantity (today's seminar comes to mind, the subject was proton
decay).
How many educational experimental papers have you seen where
the
proponent of a new educational theory reported on the unsuccess of
the
theory? Yet it is valuable to know the techniques that are
enthusiastically tried and don't work.
Regards,
Jack

In answer to Michael's question "HAS ANYONE HEARD OF SUCH A
BEING USED IN EDUCATIONAL RESEARCH?" The answer is "YES". Such "areferences):
system" (a crucial component of the "scientific method") has been
used for several years in physics education research (PER).
In Hake (2002) (in the section "Can Educational Research be
Scientific Research") I wrote (see the article for the
research
HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
There has been a long-standing debate over whether education
can or should be "scientific" (e.g., PRO: Dewey 1929, 1966,Anderson
et al. 1998, Bunge 2000, Redish 1999, Mayer 2000, 2001, Phillipsand
Burbules 2000, Phillips 2000; CON: Lincoln and Guba 1985, Sch=F6n199=
5,biased
Eisner 1997, Lagemann 2000). In my opinion, substantive education
research must be "scientific" in the sense indicated below. My
prediction (Hake 2000a) is that, for physics education research,and
possibly even education research generally: (a) the bloody"paradigm
wars" (Gage 1989) of education research will have ceased by theyear
2009, with, in Gage's words, a "productive rapprochement of thesuggested
paradigms," (b) some will follow paths of pragmatism or Popper's
"piecemeal social engineering" to this paradigm peace, as
by Gage, but (c) most will enter onto this "sunlit plain" fromthe
path marked "scientific method" as practiced by most researchreproducible
scientists:
1. "EMPIRICAL: Systematic investigation . . . (by quantitative,
qualitative, or any other means) . . . of nature to find
patterns in the structure of things and the ways they changeas
(processes).
2. THEORETICAL: Construction and analysis of models representing
patterns of nature." (Hestenes 1999).
3. "Continual interaction, exchange, evaluation, and criticism so
to build a . . . . community map." (Redish 1999)..
For the presently discussed research, the latter feature is
demonstrated by the fact that FCI. . .(Force Concept Inventory). .
normalized gain results for IE. . . (Interactive Engagement). ..
and T . . . (Traditional). . . courses that are consistent withphysics
those of Hake (1998a, 1998b, 1998c) have now been obtained by
education research (PER) groups at the Univ. of Maryland (Redishet
al. 1997, Saul 1998, Redish and Steinberg 1999, Redish 1999), theUniversity
University of Montana (Francis et al. 1998), Rennselaer and Tufts
Universities (Cummings et al. 1999), North Carolina State
(Beichner et al. 1999), Hogskolan Dalarna - Sweden (Bernhard2001),
Carnegie Mellon University (Johnson 2001), and City College ofNew
York (Steinberg and Donnelly 2002).in
In addition, PER groups have now gone beyond the original survey
showing, for example, that (a) there may be significantdifferences
in the effectiveness of various IE methods (Saul 1998, Redish1999);
and (b) FCI data can be analyzed so as to show the distributionof
incorrect answers in a class and thus indicate common incorrectphysics
student models (Bao and Redish 2001).
Thus in physics education research, just as in traditional
research, it is possible to perform quantitative experiments thatcan
be reproduced (or refuted) and extended by other investigators,and
thus contribute to the construction of a continually more refinedand
extensive "community map."Responsibility

APPENDIX - TEN PRINCIPLES OF LEARNING: THE PRINCIPLE OF:
1. CONNECTEDNESS: Learning is fundamentally about making and
maintaining connections: biologically through neural networks;
mentally among concepts, ideas and meanings; and experientially
through interaction between the mind and the environment, self
other, generality and context, deliberation and action.in
2. A COMPELLING SITUATION: Learning is enhanced by taking place
the context of a compelling situation that balances challenge andand
opportunity, stimulating and utilizing the brain's ability to
conceptualize quickly and its capacity and need for contemplation
reflection upon experiences.passively
3. AN ACTIVE SEARCH FOR MEANING: Learning is an active search for
meaning by the learner-- constructing knowledge rather than
receiving it, shaping as well as being shaped by experiences.cumulative
4. DEVELOPMENT AND HOLISM: Learning is developmental, a
process involving the whole person, relating past and present,learning
integrating the new with the old, starting from but transcending
personal concerns and interests.
5. SOCIAL INTERACTION: Learning is done by individuals who are
intrinsically tied to others as social beings, interacting as
competitors or collaborators, constraining or supporting the
process, and able to enhance learning through cooperation andsharing=
.to
6. THE LEARNING CLIMATE: Learning is strongly affected by the
educational climate in which it takes place: the settings and
surroundings, the influences of others, and the values accorded
the life of the mind and to learning achievements.to
7. FEEDBACK AND USE: Learning requires frequent feedback if it is
be sustained, practice if it is to be nourished, and opportunitiesto
use what has been learned.casual
8. INCIDENTAL LEARNING: Much learning takes place informally and
incidentally, beyond explicit teaching or the classroom, in
contacts with faculty and staff, peers, campus life, activesocial
and community involvements, and unplanned but fertile and complexto
situations.
9. GROUNDEDNESS: Learning is grounded in particular contexts and
individual experiences, requiring effort to transfer specific
knowledge and skills to other circumstances or to more general
understandings and to unlearn personal views and approaches when
confronted by new information.
10. SELF-MONITORING: Learning involves the ability of individuals
monitor their own learning, to understand how knowledge isacquired,
to develop strategies for learning based on discerning their
capacities and limitations, and to be aware of their own ways of
knowing in approaching new bodies of knowledge and disciplinary
frameworks.

"But as much as I love and respect you, I will beat you and I will
kill
you, because that is what I must do. Tonight it is only you and me,
fish.
It is your strength against my intelligence. It is a veritable
potpourri
of metaphor, every nuance of which is fraught with meaning."
