Explanation:
The most rudimentary form of painting with the brushes could be related to watercolor painting, as it is the primary step in the painting field, to get accustomed with the colors and the strokes of the brushes. This form of work is mostly found effective, to a great extent, considering the fact that it allows you to learn the strokes with a paint brush, before proceeding onto more daunting techniques. At the same time you also get the rough idea of mixing the paints, to get the desired effect. On discussing about this art we come across several aspects, which can be debated upon or could be put aside as the shortcomings or benefits of the art.
It often depends on the type of art that the teacher was looking for. For example, if a ceramics teacher was looking for a coil pot, often times they will just hand out a rubric. Typically the requirements on art rubrics are loose- otherwise everybody's work would end up looking identical. For example, one requirement could just be "a couple rows of different coil designs" for a coil pot for full points on that assignment. Art teachers also grade based on a self-reflection form students may fill out. For more abstract pieces, the teacher might just grade based on why the student designed their artwork like that.
