| Summary: | 碩士 === 國立臺北教育大學 === 數學暨資訊教育學系(含數學教育碩士班) === 94 === The purpose of this study is to explore the learning effects of cross section for sixth graders .The study adopts the approach of pre-test and post-test of singular experimental teaching of quasi-experimental research design .The subjects of the study are 34 students of the sixth graders at Happy Elementary School in Taipei City .The students’ performance in pretest, posttest , follow-up test ,the semi-constructed interview and reflection of the researcher are used as the sources of data collection. The data are analyzed by both quality and quantity in this study.
The main findings are showed as as follows:
1.The students with different achievement in math shows significant difference in performance of cross section. The performance of the students with higher mathematical achievement show better than that of lower mathematical achievement.
2.The test performance of students with different gender shows no significant difference in cross section.
3.The test performance of students in “transverse section” is the best, next in “longitudinal section”, the worser performance is “oblique section”.
4.The test performance of students in cross section is significant positive correlation with spatial ability.
5.The teaching of cross section course shows positive ,instant ,reserved and retained effects for improving student’ cross section learning.
6.The study effects of students with different mathematical achievement and different gender show no difference in cross section. All activity designs in this study are also suitable for the sixth graders of different achievements in math and different genders.
7.The cross section course shows positive and instant effects for improving student’ spatial ability.
8.After experimental teaching, the students make great progress in the performance of “cross section test”, the strategy of problem solving and spatial ability.
Finally, according to the results, the researcher propose some suggestions about evaluation, teaching, and future research in spatial ability.
