Why erasure policy in school is wrong?5 answersErasure policy in schools is problematic because it uproots spaces and erases institutional memory, which can have negative impacts on communities and individuals. The concept of erasure is seen as a psychological response to failure and conflict, and it can hinder productive institutional transformation. Additionally, erasure perpetuates deficit discourse and narrows the ways in which children can find success in school. It also violates the pedagogical truth of teaching every child based on their knowledge, strengths, and social needs. Erasure of children's potential is a result of naturalized language ideologies and socially constructed assumptions about deficits in certain groups of children. This erasure not only takes away resources and strengths but also fails to recognize and build upon what children already know and can do.

How are erasers made?3 answersErasers are made through various methods and processes. One method involves purchasing raw materials such as polyvinyl chloride, citric acid, vinyl acetate, and ethylene bis-stearamide, which are then mixed together with sulfur and rubbers to improve strength and durability. The heated rubber mixture is then injected into a mold for molding, and plastic films are coated on the prepared erasers. The film-coated erasers are packed using a packing machine and placed in packing boxes, which are also coated with plastic films for finishing the packing process. Another method involves using an eraser production line, which includes an eraser extruder, a cooling device, a printing device, and a cutting device. The eraser strip is extruded from the eraser extruder and passes through the cooling device, printing device, and cutting device. The printing device allows for different patterns and colors to be printed on the eraser, meeting various production requirements. Additionally, a clay for manually self-made erasers can be produced using thermoplastic elastomer, plasticizer, filler, stabilizer, and toner. This clay is easy to shape, environmentally friendly, and can be used as a DIY material for erasers. Eraser processing equipment is also available, which includes an extrusion molding channel, guide rail, movable block, and material carrying blocks. This equipment allows for shearing, printing, and hydraulic rod mechanisms to be used in the eraser production process. Finally, eraser machining equipment enables automatic printing and cutting of erasers, improving production efficiency without the need for manual operation.
