碩士 === 國立臺灣師範大學 === 科學教育研究所 === 91 === Investigated were the misconceptions of tide of perservice teachers with different science background and science majors. There were 241 perservice teachers from three national universities involved. Survey and interview methods were adopted. 「The Test of Tide for Perservice Teachers of Jounior High School」 was developed by the author. The tool had been evaluated by three experts. The test-retest reliability was .77. Data was analized through descriptive statistic and ANOVA. Some preservice teachers were interviewed for specified items. The results showed there were three type of misconceptions about tide held by preservice teachers as follows：（1）tide-generating force：the gravitation from the moon or centripetal force from the earth rotation makes the sea level higher on the surface of the earth which is not facing the moon；（2）low tide and high tide：the sea level on the surface of the earth which is not facing the moon and the Sun was low tide and when the moon and the Sun were the same direction, the sea level on the surface of the earth was high tide；（3）the factors affected the size and the time of tide：the sea level on the surface of the earth was the lowest called neap tide and when the earth was at perihelion and the moon was at perigee, the sea level on the surface of the earth called spring tide. Preservice teachers who had studyed one of oceanography、the introduction of oceanography or physical oceanography understood tide sigificantly better than those who did not have the above courses（p＜.04）. Preservice teachers majored in earth science understood tide significantly better than other majors（p＜.04）。
