| Specific purposes | ・ Touching and observing the three-dimensional model of geologic strata (with a fault structure) facilitate students understand that geologic strata spread also toward the depth as well as lengthwise and learn fault systems. |
| Considerations for disability characteristics |
Sectional views of geologic strata are printed in braille in textbooks used at junior high schools and high schools for the blind. However, it is difficult for students to fully realize the actual expansiveness of strata just from such views, which are mere excised samples. Actual strata spread not only laterally (right and left) but also in terms of depth (front to back). There are also sections cut by faults. We prepared three-dimensional models of geologic strata (with a fault structure) for students to observe by touching aiming to facilitate them to imagine the expansiveness of strata and learn fault systems. One model was prepared for each student. The dimensions were decided so that the model would be easy for students to observe and move the pieces with both hands, reproducing faults. The models are made of wood. Their dimensions are about 10cm high, 10 to 15cm wide and about 5cm deep. The size is easy for students to hold and observe. Sectional views, either 3D copies or in braille, are pasted on the surfaces. |
| Expected effects and results | By touching the three-dimensional model, students can realize that geologic stratum spreads not only sideways but also toward the depth. By moving the pieces, students can understand fault systems, such as normal and reversed faults. |
| How to use |
Use the three-dimensional model at the start of geologic stratum lesson and for teaching fault systems. In the lesson on geologic stratum, hand out one model to each student so that they can observe the models at the same time. First, ask students to touch strata and confirm that the same stratum marks appear not only on one surface but on all four surfaces, and let them notice that soil forming a stratum has deposited on a horizontal plane. In the lesson on fault systems, ask students to hold and slide the right and left pieces, and let them notice that a fault is formed when the pieces are slid. Make them actually form normal and reversed faults to facilitate understanding the differences between their systems. |
