Introduction Nanotechnology is a unique branch of science that deals with materials in a very small size between (1-100 nm) with different crystal shapes such as spherical nanoparticles, nanorods, nanoplatelets, nanoribbons, and flower-like.
Semiconductor materials were mainly interesting due to their great practical importance in optoelectronic devices and electronic such as magnetic storage devices, catalytic activity, catalase mimic, electro chemical cell [16-19], and at crystalline structure of the prepared CuO was characterized by diffraction (XRD), Atomic force microscopy (AFM) and antimicrobial application [20].
Our study aimed to prepare copper oxide (CuO) nanoparticles using inexpensive materials, by famous way (Sol-Gel) and estimate the surface morphology of the nanoparticles.

After the above step, it is proper for students to find out proper learning materials to enrich themselves.
Autonomous leaning abilities Character-oriented education to success Information technology Teaching strategies Learning strategies In order to reach aims of "character-oriented education to success", all learning materials must be enough, banausic and linguistic learners must have abilities to learn learning materials very well.
In the resource pool, all kinds of learning materials must be graded for different levels of students.
Furthermore, testing materials can be in accordance with learning levels of students.
