Regional Teaching materials and Children\u27s Learning : Based on Takako SUZUKI "Teaching of the River"

Regional teaching materials are important in social studies.Teachers can investigate regions around schools,and collect various teaching materials.Children can investigate themselves,and learn fruitful learning through them. In this paper I tried to consider how children learn their familiar region by means of analvzine the concrete utterances and compositions of the children in the class

Educational Expenditure of Family Finances in Post-"Bubble" Prosperity

What we called Bubble Prosperity began in the end of 1986,and ended in 1992. People had bought goods of higher grade in the times, and expenditure per household increased. Expenditures on education increased in particular. But consumers\u27 behavior changed in post-Bubble Prosperity, and people came to prefer cheaper goods. Expenditures on education decreased significantly in 1993. But those who bring up their children feel heavier burden than ever with expenditures on education in post-Bubble Prosperity. In this paper, I tried to give the explanation of this contradiction. Though expenditures on education per household with children decreased, psychologically people spend money as largely as possible for education of their children

The Dispute about "Education of Modern History" Reconsideration of "Education of Modern History" and Its Criticism

There are a hot dispute about "Japanese education of modern history" in recent days between "the society for the study of the liberal view of history" and its criticizers.The society insists that modern Japan has been explained too ill in Japanese education after the World War n. The criticizers are positive in denying the insistence of the society.I tried to summarize the dispute in this paper

Middle Power Measurement in Semi-tethered Swimming using Ergometer Attachment

The purposes of this study weie to measure middle power, energy which had been supplied mainly from the lactic acid system, during swimming using an ergometer attachment and to evaluate swimming performance by this middle power To perform these purposes, a middle power measurement test in semi-tethered swimming (STS33) using an ergometer attachment was developed In STS33, the load of the ergometer attachment was set to 7.0kg and the power measurement interval was set at 5.0 seconds The subject was instructed to swim at full strength for 33.0 seconds Power measurements using the ergometer attachment were taken 3 times during the 33.0 seconds at the end of 10s, 20s and 30s respectively The first measurement (1st measured phase) was taken between 5 and 10 seconds from the start of the swim The second measurement (2nd measured phase) was taken between 15 and 20 seconds of the swim, and the third measuiement (3rd measured phase) was taken between 25 and 30 seconds from the start of the swim by the present investigators As in preliminary experiments, the exercise intensity of the STS33 was measured as the average blood lactate concentration produced by the work rate After each STS33, a blood sample was taken by a licensed nurse under supervision of a medical doctor Subjects were 5 junior elite swimmers designated to tram by the N prefecture Swim Association The group mean post exercise blood lactate concentration was 10 5mM/l These concentration of blood lactate was greater than the OBLA measurement of 4mM for lactate accumulation developing in the middle phase of a swim trial This result led to the conclusion that the STS33 test could be used to evaluate the middle power In a main experiment, 21 male elite junior swimmers were measured Middle power in swimming in each subject was measured by the above-mentioned STS33 and the relationship between the group mean middle power and group mean total swim time was analyzed The relationship between the average power (P watt) of the 3 measured phases in STS33 and swimming velocity (V m/sec) in 50m event was P =-134.53 + 87.02 V (r = 0.880, p≦0.001) The relationship between the average power (P) of the 3 phases in STS33 and swimming velocity (V) in 100m event was given by P = - 191.95 + 128.92 V ( r=0 940, p≦O.001) From these results, the middle power in STS33 is appropriate for evaluating swimming performances in 50m and 100m event
