| Summary: | 碩士 === 國立雲林科技大學 === 資訊工程研究所 === 95 === Inductive reasoning is an important domain-general skill for learning science and math, etc. Unfortunately, previous studies have pointed out that students of elementary school still have many weaknesses, when they do the tasks of inductive reasoning. In this thesis, we have designed a web-based environment to address some of these weaknesses, and train their skills of inductive reasoning. We adopt the pedagogy of self-directed experimentation in the learning environment, which guides learners to discover geometry concepts and hidden causal rules. According to the three phases of inductive reasoning, i.e. data collection, hypotheses generation and evaluation, we have designed several assisted tools that attempt to help learner improves their development of experimental strategy, and increases the accuracy of hypothesis generation. In the experiment, learners who were assisted by tools used more control variable strategy in the phase of data collection, and the accuracy of their generated hypotheses were higher than those without using the tools.
