All educators should give their very best to assure that their students optimally learn, regardless of a school’s zip code or location, regardless of the race or socioeconomic status of any students, or whether students are mainstream or SpEd. Even the lowest functioning students should receive routine and adequate instruction in all subjects appropriate for their ages or level of progression.
Imagine students being placed in SpEd classes, and they have no learning disabilities. Imagine students who are of age and grade where they should be capable of reading and cannot. And the only problems in both scenarios were/are instructional methods, or the students merely need(ed) additional elaboration or tutoring on certain course material that they were too bashful to request; and their instructors never followed up with something as simple as corrective grading (returning graded papers and rendering, in distinctive ink, correct answers and written examples, where relevant, showing step by step methods of solving problems similar to those missed, and requiring students to correct missed or similar problems for homework).
Imagine a blind, deaf/mute and/or incapacitated student never being taught more than basic information, when they are capable of much more than realized, as their schools never introduced them to braille or sign language, etc. Blind, mute, deaf, or incapacitated, all students can learn, and all students should be taught, the blind indeed via braille, the mute and deaf indeed by sign language, the incapacitated by normal methods, physical therapy, etc., as if recovery were possible, and as if such were the means; and appropriate methods and means of instruction should commence in early childhood, upon initially entry into school.
When an instructor gives anything less than their best they compromise futures, their students,’ their own, those of communities, and that of the world. Mediocrity should never be among the options.
