國民學校 低學年의 記數法 指導에 對하여 = How to Teach Decimal Notation in Low Grade of Primary School

다국어 초록 (Multilingual Abstract)

This is an experimental work to understand decimal notation. It was discovered that the majority of error types of accounting was due to not knowing number placement according to my first investigation on 600 children from the second grade to the fifth grade. My second investigation to let 896 children in three primary schools write numbers from 11 to 20 showed that 54 percent of error types also resulted from the negligence of decimal notation or number placement. Stimulated with these results the third research was made in cooperation with above school teachers to separate tens' place from ones' place with a teaching implement shown in §5 and to teach decimal notation, emphasizing number placement. The class with this teaching method had a good result, that is, the error made was from 56 percent at the second examination to 61 percent at the third whereas other classes without any experimental direction resulted from 47 percent at the second examination to 70 percent at the third in average. When 5 percent level of significance is used this teaching method has been proved its excellence.
