It is believed that additional materials are required to implement the energy education among the schools based on current teaching style.
In this study, energy teaching strategies can be classified into the following types with their connotations: (1) Collaborative learning: using team learning for a collaborative achievement and jigsaw method, teacher can group the students and divide the teaching materials into units.
Computer aided teaching, concept mapping, metaphor and analogy can be used to help the teaching activity; (3) Thinking approach: using some properly designed materials, we can enrich and philosophize the teaching for thinking with some utilities and help the students in their thinking.
We evaluated the number of science and living technology teachers in whole Taiwan region based on this ratio.

The J–C model constants are readily available for common metal materials in machining such as steels, aluminum alloys, and titanium alloys.
The J–C model can be expressed as the following equation: (1) Where A, B, C, m, and n are five materials constants.
