Description

Technical Field

[0001] The utility model relates to the field of sitting posture restraint correction, in particular to a table and chair for restraining children's sitting posture. Background Art

[0002] Researchers have found that children with ADHD, intellectual disabilities, and autism have low self-control in the classroom and are prone to disruptive behaviors, which puts great pressure on classroom management. Therefore, the high incidence of problem behaviors in children with autism poses a dual challenge to teachers in teaching and management. From the current situation of special education, whether in special education schools or private special children's rehabilitation institutions, whether in individual training classes, group classes, or collective classes, students' problem behaviors have become a major obstacle in the teaching process. Classroom disruptive behaviors not only affect their own learning and development, but also interrupt the teacher's teaching activities and affect the learning and activities of others. Therefore, such behaviors often cause teachers' disgust.

[0003] Specifically, disruptive classroom behavior refers to the behavior of interrupting other people's ongoing activities in a verbal or physical way during class time, affecting the teacher's teaching and other students' learning, disrupting the classroom order, and causing trouble to one's own learning and interpersonal relationships. It includes verbal disruption and behavioral disruption. Verbal disruption specifically includes talking to oneself, repeating what others say, speaking without the teacher's permission, etc.; behavioral disruption includes disrupting others' work, making noise (intentionally or unintentionally), touching others' bodies, taking others' things without permission, leaving seats, etc.

[0004] In order to deal with this kind of disruptive behavior in the classroom, the main means include positive behavior support and PEO model intervention. Among them, positive behavior support mainly includes ecological environment, control strategies, antecedent control, behavior teaching and consequence handling strategies. Studies have pointed out that this is an effective method of intervening in problem behaviors. It can effectively reduce the disruptive behavior of children with autism in the classroom. However, the management cost of teachers is relatively high, and real-time attention is required in the classroom, and it depends on the level of intervention of teachers. PEO model intervention refers to intervention from the dimensions of people, environment, and homework activities to improve homework performance. Some researchers pointed out: the use of alternative seats can achieve the modification of part of the personal environment; the use of alternative seats may provide ADHD students with an opportunity to seek sensory input in a positive and appropriate way.

[0005] Alternative seating is a classroom modification technique that increases the amount of sensory stimulation students receive while sitting. This is achieved by allowing students to continually move and adjust themselves without leaving their seats. Alternative seating is a sensory-based intervention often used by occupational therapists to encourage students to be active in class and meet their sensory needs in an appropriate manner. This alternative seating can be in the form of a sitting positioning chair, a therapy ball, a therapy cushion, or a variety of other seat modifications. However, traditional sitting positioning chairs use passive constraints, have poor adjustment capabilities in all dimensions, and poor comfort. Therapeutic balls and the like require high interactive participation from teachers, and are suitable for sensory integration classrooms but not for classroom teaching. Therefore, the utility model provides a new solution. Utility Model Content
