The purpose of this study is to compare the units of elementary science textbooks in Korea, Japan, and the USA and correct writing of Science Units through the questionnaire of 259 pre-service elementary teachers.
There are more units in USA than Korea and Japan in result of the comparative analysis of units in elementary science textbooks. In common, the number of units are increased and the difficult units are used in various usage according to the higher grade. In particular, metric system(SI) and yard pound units are used together in USA elementary science textbook. In the units writing comparison, USA is written according to the International Bureau of Weights and Measures(BIPM) except for temperature(oC) and percent(%), while Korea and Japan do not follow the standards.
Pre-service teachers were writing correctly except for the temperature and the quantity of electricity. They used wrong korea words ‘per’ instead of ‘mae’. For spacing indication, half of the respondents chose the answer in the case of temperature(oC). Specially, the spacing of “time”, “minutes” and “seconds” indicating time was completely misunderstood. They do not use the small and the large letters correctly too. The combination of one or more symbols should use with parentheses and negative indices, but the answer rate was low. And for the interpretation of combined unit, in the case of speed and wattage, teachers understood well but in the case of wind speed, they did not recognize as well as the population density and fuel efficiency. In the positive and negative prefixes we use commonly, teachers do not understand it because they do not use it in real world.
In the future, KRISS should develop the unit continuously. We have to use units in the right usage in the daily life and more training and teaching time is needed in the education field.
