The aims of this study are discovering the elementary school students’ difficulties in learning “spatial location” and students’ effects and evaluations through the designing progress and practice of the teaching module.
The method of this study is case study. The objects of this study are selected into two periods. One is to discover the students’ difficulties: the objects of this period are the elementary fourth grade students who were all taught by the writer in Changhua County. The other on is the remedial teaching: the objects of this period are the students who can’t have correct concepts about space after learning the subject, “spatial location”. (Six students received the remedial teaching.) Through this study, the writer gets the following results and suggestions.
一、 The results of this study :
（一） Students’ difficulties in learning “spatial location”：1. The misidentification of basic locality. 2.Being unable to confirm the reference point. 3. Being unable to follow the change of reference coordinates to distinguish the correct direction. 4. Being unable to recognize the left and right directions correctly when the situation is changed. 5. Being unable to explain the routes of movements specifically and correctly. 6. Being unable to transform large space into small space and draw it as a plane picture specifically and completely. 7. The limits of the abilities in transforming three-dimension space into two-dimension space.
（二） The design and the modification of the web-based module: The modifications and sophisticates of the module are constantly. Take this study as an example. The whole progress can be divided into the “brewing” : to raise the modification of the researcher, the “developing” : to construct the blueprint with simple multimedia materials, the “conflicting” : to find out the defects of the design through showing the module, and the “integrated modifying” : to integrate the modifications and mix them into real teaching.
（三） Students’ performance in practicing web-based module: Learners have positive views about teaching with information technology. It can enhance their learning motivations. As to learning materials, we can get the following results. 1. Students’ acceptances are higher in the materials which are easy to read and understand. 2. With the assistance of computers, students can transform a three —dimensional picture into a plane one, and the drawing abilities of large space are also enhanced. 3. Students can accept wider learning materials. 4. There is an enhancement in students’ abilities of transforming coordinates. 5. Students can locate the objects, and then describe the locating relations between the objects and the movement routes more specifically.
二、 The suggestions of this study:
（一） The suggestions of teaching about spatial materials: 1. The materials are from the life and applied in the life. 2. Instruct students to find out the relations of referencing coordinates. 3. Train students to find out the reference points from the relative locations. 4. Encourage students to try thinking more, and treat the performance of spatial ability as a kind of creations. 5. Teachers should train students to transform three-dimension space into two-dimension space.
（二） The suggestions of the teaching with information technology: 1. Teachers can design the information technology materials with the ideas of “cooperative learning”. 2. Teachers can design more materials about information technology and set up the environment in which we can share teaching materials. 3. Teachers should value the process of constant modifications when designing web-based course.
