Doctoral Dissertations

Problem-solving is one of the standards of mathematics processes developed by the National Council of Teachers of Mathematics. Many research studies indicated that there was a relationship between mathematics achievement and spatial visualization skills. But the research results still didn’t indicate whether or not there was a causal mediation relationship between the achievement of learning-and-practicing three-dimensional geometry and mathematical problem-solving skills mediated by spatial visualization skills. Therefore, it’s still necessary for us to specifically investigate whether or not spatial visualization skills can be a medial factor between the increase of mathematical problem-solving skills and the effects of learning and practicing …
