| Summary: | 碩士 === 國立交通大學 === 理學院科技與數位學習學程 === 100 === Cabri 3D, a dynamic geometric system which is quite popular in the field of mathematical teaching, is a powerful software used to draw the geometric figure in the three-dimensional space. One of the main features of Cabri 3D is to help learners observe the characteristics of space geometric figure from various angles through dragging the geometric figure into different direction, so that the concept of mathematics can be more comprehensible.
The research aims to take the Space Concept in 99 Curriculum as an example and the method of quasi-experiment is adopted. With the combination of Carbi 3D and Power Point to instruct the concept of the space geometric figure, students’ motivation can be aroused and their exploration is proceeded. By inference and demonstration conducted by traditional blackboard teaching, students’ correct concept of space can be built, which is beneficial to the learning of the plane and line in the space in next unit. The research aims to explore whether better learning effects can be achieved with the use of Cabri 3D-assisted instruction, compared with the traditional teaching.
The major findings are summarized as follows:
1.Cabri 3D-assisted instruction can benefit the middle and low proficiency learners in
learning the concept of space and has remarkable effects on students’ learning, especially in these fields such as projection concept, dihedral angle and theorem of three perpendiculars, which are difficult to present by traditional teaching.
2.Cabri 3D-assisted instruction can reinforce students’ retention of space concept after learning this concept, which helps explore and develop the conception of space in the long-term memory.
3.Cabri 3D-assisted instruction has a positive effect on students’ learning of the plane and line in the space in next unit.(The summary is for reference only.)
