these pages are condensed from a pamplet of the above name published by Science Education Center--University of Oklahoma. The "metaphor" is that schools (like dinosaurs) -- are going to be extinct if we don't do something. Many years ago the authors of this article were my teachers.

but scientists are supposed to be objective! They are supposed to base their conclusions on experiments and the logical application of basic theory. How is it then that science is awarded such a prominent position in the school curriculum if scientific conclusions are so rapidly outdated? . . .each generation studies science far differently than their parents studied. . . has the art of science teaching conquered the apparently built-in obsolescence of the content students study?
a perfectly logical way to develop an understanding of why science and other subjects are taught is to examine HOW it is taught and determine FROM those observations the OBJECTIVES of the teacher in the school system. IS THIS THE WAY?
... take the way that the law of levers is taught in JHS. Being aware that visual aids are quite important, the teacher probably ...
diagrams a first class lever on the board --
labels the parts --
indicates with arrows & diagrams of a small weight where the force is to be applied . . .
The student is expected to learn what the terms "force" and "weight" imply -- what a fulcrum is -- and that (Fe) x (e) + (Fr) x (r).
no learning can be complete unless some understanding is demonstrated on the part of the student. The objective test is often used as a means by which understanding, developed through lecture, can be evaluated. The answers that students provide on these tests are cited as evidence that he has LEARNED.
This is a method by which the students may observe these phenomena when one of the following apply:
Consider the teacher who wants to show the students that the muscles of the body are controlled by the discharge of electrical energy along the nerve ganglia. . . the teacher administers an electric shock to a freshly killed frog . . .all day long. By 7th period, the frog will no longer move, and the demonstration "doesn't work". Even if a new frog is used each period, the TEACHER is the ONLY ONE having the experience of INTERACTING WITH THE MATERIALS!
* What is scientific literacy? * What is there about science that can contribute to the education of children?
in "The Central Purposes of American Education", the Educational Policies Commission states that the major responsibility of the school is to foster that development of individual capacities which will enable each human being to become the best person he is capable of being. This can be accomplished by developing the ten rational powers.
These are:
recalling and imagining
classifying and generalizing
comparing and evaluating
analyzing and synthesizing
deducing and inferring.
learning to know and to understand
questioning of all things
search for data and their meaning
demand for verification
respect for logic
consideration of premise
consideration of consequences.
The OBJECTIVES of science education for ALL educational levels, therefore, must be: The learner will ...
does listening to a lecture ...
lead a learner to develop the ability to analyze, synthesize and generalize?
does following instructions in a lab manual ... develop a student's ability & confidence to inquire?
does learning FeZe = FrYr, and electricity stimulates the ganglia ...
lead to an understanding of matter, life, energy and their interaction?
in order to achieve the objectives of science for the present as well as future generations the inquiry method of teaching must become dominant. The objectivs of science education can ONLY BE ACCOMPLISHED WITH BOTH the student and teacher are actively engaged in classrooom activities which are inquiry oriented INQUIRY, INVESTIGATIONS ENABLE THE STUDENT TO SERVE THAT FUNCTION IN THE CLASSROOM. These inquiry type situations enable the individual to develop his rational powers, but he MUST BE GIVEN THE FREEDOM to investigate and form hypotheses by analyzing, etc.
THE ROLE OF THE TEACHER is not that of a source of correct information; rather he provides clues, asks questions, gives encouragement, and offers advices if a student "hits the panic button" while investigating.
TIME WOULD NOT have to be considered as a major factor in the investigations. The students must have time to explore the problem being considered and the materials available to be used in its solution. Time is necessary for the student and teacher to interact to facilitate the invention of concepts. Time must be provided for the student to again interact with materials to discover the applicability and meaning of the concept. Such time allotments are not now allowed in present school situations.
not only do students develop his rational powers in an inquiry centered classroom but their confidence increases as he begins to form their own ideas instead of using only those given by the teacher. With this self-assurance, students can search for understanding and use those abilities that will enable them to meet any situation in life, and the development of the ability to meet and function in any situation in life, as we beieve, the primary reason the taxpayers support the schools.
CHANGES TO BE MADE
instruction in inquiry teaching should be REQUIRED IMMEDIATELY in all TEACHER EDUCATION PROGRAMS and all persons currently involved in education should have an in-service or summer experience in inquiry instruction. The entive system, from K to Post graduate school should be restructured to accent inquiry approaches... professors of education must use this method and discontinue TELLING students how to teach. Pre-service teachers should be required to observe and teach inquiry-oriented classes much before they begin student teaching.
IN FACT, IF PROSPECTIVE TEACHERS HAVE NOT HAD A CONSIDERABLE AMOUNT OF EXPERIENCE IN PRE-COLlEGIATE CLASSROOMS BEFORE THEY STUDENT TEACH, THAT EXPERIENCE IS OF minimal value AND IS PROBABLY MORE ritualistic THAN instructional.
College students must have experience with children who are learning by inquiry, during every year of their college years.
administrators must support ... changes ... and those who now judge the performance of the teacher by the amount of silence and lack of student-student interaction in the room must replace those values with ones consistent with inquiry.
THEE goals of our present educational system reflect the expectation of society and achieving those goals often tend to mold the learner for the existing society. Such a procedure is inadequate for solving today's problems, and the future poses even more serious threats. Means of counteracting those threats cannot be found in the schools of yesterday. But where can the annswers and means be found? Perhaps the following articles may help you to formulate your own oppinions.
