Postwar science education
Content of the unit (2 school year Ⅴ) : How is the electricity used in home and society ?
Problem Method of learning
Learning activity
1.How is the electricity utilized in the home? (2) What kind of mechanism do electric heater and iron become?
Observation The structure of each part is observed by the decomposition of electric heater and iron.
Experiment and explanation of the teacher
Some quantity of water is boiled by the electric heater, and the relationship between heat quantity and used electric energy is examined. The teacher explains summarizing this relationship.
Research and discussion
In comparing the electric heat with gas, charcoal and other fuel, the loss is studied and is discussed.
Table Unit example concerning electricity in the tentative plan of the 1951 science course.
No.6
*Science education to “life component Unit” was demonstrated in postwar
From life component to systematic science
*Problem of the life component unit learning
No.7
*Movement of systematic curriculum
(1) One of the reasons is not to improve the education condition to teach the life component .
(2) One of the reason is the effect on the remarkable lowering of the basic scholarship.
Because of above problem, the movement to the direction of developing a more logical and systematic science curriculum, and to improve the level of scholarship of pupils .
Feature of revised science curriculum
Table Content related to the electricity in the 1958 science course of study
No.8
*Examples of everyday life component were harmoniously included in the systematic teaching of theoretical science.
Content ( 3 school year of 1 field (5) ): The radio wave can be received and summary of the atomic structure are guided.
Item Explanation ExampleB. Radio wave and radio(B) Radioa. It is known that the alternating current in corresponding to radio wave flows when the antenna receives radio wave.b. By the alternating current that flows in the coil, it is known that the voltage is generated in double end of the coil.
Possibility of the musical selection through the condenser is included in circuit of the combination of condenser and coil, but it does not touch the mean of the tuning. As the voltage drop is generated when the current flows for the resistance, it is noticed that the voltage generates in the double end when alternating current flows in this coil, and that the radio can be received by the taking out voltage.
By connecting the detector and micro ammeter with the double end of antenna coil, it is examined that the current flows.

Criticism to new Industrial arts and homemaking
* Criticism to new Industrial arts course
No.11
*Effect of modernization(1)The new approach by the modernization of education in
the U.S.A was studied by the Council.
The repetition of the applied content of the science course in the industrial arts and homemaking course was criticized by the mathematic education party at that time.
(2) Because of the effect on the above modernization, the curriculum resulted in greater selectivity in the contents of the 1969 revision of the junior high school course.
Table Content related to the electricity in the 1969 science course of study
No.12
*the modernization of the science curriculum resulted in greater selectivity in the contents of the 1969 revision
Content ( 3 school year of 1 field (9) ): Current and magnetic field
Item Explanation Example of experiment and observation
B. Electromagnetic induction.
(A) The magnetic field changes in coil, and the induced current flows in the coil. (B) The induced current flows in the direction where prevents the change of magnetic field, and the work must do in order to run the induced current. (C) The generator is possible to change the mechanical energy to electric energy.
It is taken up that the induced current flows in the coil when the magnet takes in and out by connecting the micro ammeter with the coil. The shaft of the generator rotates, and the electric energy arises.
The material on radios and radio waves was omitted !!

Conclusion
(4) By a disruption in the revised the industrial arts and homemaking course in 1998, the systematic relationship between the contents of scientific and technical education was weakened.
(1) The introduction of examples of applications of scientific laws and principles in daily living was recommended in the postwar science curriculum.
(2) The application of scientific laws and principles on technology was included in the new curriculum of the 1958 industrial arts and homemaking course.
(3) The gap between science and technical education was filled by changes to the industrial arts and homemaking course, so that a new systematic relationship was established.
