We proposed a good calcinations condition of the ZnO disk to control the crystallography and nanoparticles in ZnO disk. The crystallography of precursor powder and disk powder were analyzed by the X-ray diffraction (XRD). The mean nanoparticles of ZnO disk was determinate by XRD results and observed by scanning electron microscope. The temperature ranges of 400℃ to 650℃ in air for 30 minutes were used calcinations ZnO disk. These temperature can be controlled the single phase, lattice parameters, unit cell volume, crystalline size, d-value, texture coefficient and bond lengths of Zn–Zn, Zn–O and O–O which correspond significantly the hexagonal crystal structure. The nanoparticles were small changed mean of 76.59 nm at the calcinations temperature range

The Science Technology Engineering the Arts and Mathematics (STEAM) education was trend to change from traditional education philosophy based on standardized test scores to a modern trade learning process. We proposed the innovative thinking skills for under graduate, graduate and high school students in ASEAN counties using new fabrication of thermoelectric device (TED) kit. The TED kit was developed to understand and create basic science and applied science knowledges such as energy, heat, heat converse to electricity, materials and micro generator and refrigerator applications. The 300 students from Indonesia, Myanmar, Vietnam, Loa, Cambodia and Thailand counties have ASEAN-TED Workshop 2018 in SakonNakonRajabhat University (SNRU), Thailand. They are most satisfaction with designing and fabricating thermoelectric cell and thermoelectric devices by them self to create a knowledge of technology and get new idea innovation. The workshop has impacted with students to fabricate new 18 thermoelectric prototypes developing to innovation show and competition in ASEAN-Thermoelectric device fabrication and invention fair 2018 on 1st August 2018 at SNRU every year.
