Analysis of Educational Spaces Design Methods for Educable Mentally Disable Children A Case study on 6-17 years old childrens

This study aims to investigate and analyse design and optimisation methods of educational and recreational environments for educable mentally disabled children. This study is conducted using a descriptiveanalytical method based on library research, documents and field surveys. The research studied sixty mentally disabled children aged 6-17 years, twenty instructors and sixty mothers through purposive sampling. Then the quantitative data of questionnaires and the qualitative data of interviews and paintings are analysed using SPSS and Excel. The results of this research determine the useful criteria used to design an attractive and friendly environment for mentally disabled children. In addition to promoting the sense of safety and security in these spaces, it improves recreational activities of mentally disabled children both individually and collectively.


INTRODUCTION
The human and environment relationships have been an inevitable long-standing part of architectural research (Mostafa, 2008).Various studies have shown that the quality of the situation where the person works, e.g.space, colour, light, sound and contentment, affects his perception.Hence the mutual relationship of architecture and psychology is necessary to better design spaces (Tabaian, 2014).Architecture, as a profession, is responsible for creating environments that are compatible with a variety of user needs.The particular people should not be excluded in this regard.There are always people with special needs in the community, e.g. the deaf, blind and those with other psychological and physical disorders.These people are a part of society and require the services and attention as much as others need.Accordingly, people with autistic spectrum disorders are identified as those with special needs that require consideration.The child learns and understands his environment according to his individual needs and competencies.The research obtained environmental information through perceptual processes which are driven by the mental schema and guided by human needs (Lang, 1987).
According to the fifth edition of Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), intellectual disability (ID) is introduced by three general criteria including defective mental functions, difficulties in adaptive performance in terms of conceptual, social and practical aspects and problems during the developmental period (Cabarcas, Espinosa, & Velasco, 2013).Intellectual disability is a disorder characterised by clear limitations to intelligent and adaptive behaviour (Vargo, 2015).According to the DSM-IV, about 1% of the population has mental disabilities, and its prevalence rate is a function of age and varies according to it (Ganji, 2013).In Iran, 2800000-8400000 people having a disability (Abbasi et al., 2011), of which 28795 have mental disabilities (M Alagheband et al., 2011).Despite the high prevalence of mental retardation in Iran, architectural design strategies have not been specifically addressed to meet the needs of this group.Mentally disabled children and adults are generally disregarded by the community of architects (Fig. 1), and the architects must be familiar with the morale and needs of these people and attempt to create ideal environments for them.

Today, there are many rehabilitation and educational centres for mentally disabled children in the world that have been established to improve them.The Friendship Circle is located in the west of Bloomfield, Michigan, USA.It provides services for social skills, daily camping and staying overnight, baseball and cycling training, etc. for children with special needs.The Friendship Circle offers over 40 programs designed to develop social, physical and constructive skills of the children.Brown School is located in Pinetown residential area.Pinetown is a location between Kloof and Westville, from which takes 10 minutes to reach the city centre.It is an industrial area, but there are residential houses there, and now it is one of the most critical areas in Durban.The school is enormous and arranged in such a way that classrooms are connected through long corridors, resulting in excessive circulation.There is a wide range of sports facilities, such as cricket, basketball and tennis courts, all of which are used most of the time and this is an important issue.In general, classrooms are large and benefit from good lighting, in addition to the porches used by trainers.Girih tiles are used extensively in the facades, and the texture of bricks is tangible by touching, referring to the spatial readability.It generally seems that the school possesses enough space for all children, although a vast area of the site cannot be used due to the separation of sports spaces from other parts of the school (Tabaian et al., 2015).
Open Air School is a particular school for children with various types of disability, e.g. the blind, deaf and autistic.This place serves 260 elementary students up to the age 13 with a variety of activities for children.The school is located within an open space on the outskirts of Glenwood, Durban, under control Glenwood High School and Glenwood Elementary School.The school is located on a great site; it also offers several sports facilities in cooperation with other schools.There is a parking area outside the school for parents to take their children, but it is not big enough to lead wheelchairs from the street to school.There is a sizeable inviting facade indicating the entry into the school.
However, there has not been constructed any educational-recreational centre for mentally disabled children Iran.According to the information provided by Iranian Department of Education, there are only three camps for mentally disabled children (in Mashhad, Hamedan and Chamestan), where no educational services are offered and are used just as accommodation for these children and their families.Thus the central question of this study is that which design criteria can lead to an attractive and friendly environment for the education of mentally disabled children to promote the educational and cultural activities of this group.Since these children have different needs, their educational environments also involve a particular design.

RESEARCH METHOD
Hence the study is applied research based on its objective.On the other hand, a descriptive-analytical method is employed because the research process describes the characteristics of mentally disabled children and applies their views and participation to facilitate decision making and present the final model.Quantitative data (questionnaires) and qualitative (paintings, interviews and observations) are used in this study.It should be noted that the quantitative data is collected through survey and cross-sectional research in this study.Since the collected questionnaires attempt to assess current conditions, the samples are taken from the population in a specific period.Since the qualitative data, especially children's paintings, represent their thoughts, behaviours and feelings and the researcher attempts to interpret and codify the desirable behaviours of children in the cultural-recreational environment, the qualitativephenomenological nature of the research is also essential.The statistical population is selected from 7-15-year-old children and their teachers and educators through the purposive sampling strategy.Moreover, the teachers and educators are also chosen through purposive sampling, since it is aimed to provide the same environment for the child and teacher (as an expert) and their interaction.
The information is collected through library and field research in this study.In the library research, documents and sources such as Persian and Latin books and articles are referred for initial investigations and examination of the experts' views on children and their educational-playing spaces, resulting in studies about the characteristics of mentally disabled children, the causes of this disorder and research on educational-recreational areas for these children.In this method, the primary data were collected at first and then categorised and used indirectly.In the field research, the researcher attempts to collect information through observations, paintings, interviews and questionnaires.In a direct view, the researcher initially observes, records and takes photos of the children's behaviour in cultural-educational spaces by visiting the internal samples (Farshchian Primary School and Behesht Association for Children in two branches).Then, the children's response is observed and recorded during playing (break time).Given that children's participation, attitudes and interests are the priorities that must be concerned in the design of spaces for children, their paintings are investigated in this study; so pictures of two topics (1.free subject, 2. purposive subject) are collected.A questionnaire (including ten questions, 60 parents) is prepared for obtaining information from teachers and mothers of these children.
The field research is conducted in schools and associations which support these children.Therefore, Farshchian Primary School for girls and Behesht Association for Children are selected to do these studies.The research takes 45 minutes for every six students on morning shift for three days.According to the research method, the necessary explanations are provided based on the purpose of this study before giving A4 sheets to the children and questionnaires to the mothers and teachers.Teachers are also advised to respond to questions about their school conditions realistically, and the children are also asked to paint their favourite space.Various accessories (colour pencils and pastels) are provided for children to have no restriction for painting.After collecting the paintings, each child is asked to give explanations about his/her painting details, and the researcher takes note and records the keywords.A survey is also conducted among children about the album (samples taken from cultural-educational centres).In the present study, the qualitative data is analysed using descriptive statistics.

Observation Result
This study aims to achieve the principles and rules to design educational environments for mentally disabled children and improve the quality and efficiency of such spaces.The qualitative data and research findings, including interviews and paintings, are presented in Table 1 using a descriptive approach Table 1.The desirable spaces from children's point of view.

Furniture for children
In children's spaces, furniture should be lightweight, portable, soft and comfortable.

Adults' accessories
Attention to small-scale devices and materials resembling adults' jobs can be useful to discover their potentials, e.g.small-scale kitchen, soft and lightweight construction materials, guide signs, etc.

Pictures, books, bookcases
A bookcase especial for children may provide a calm environment to read stories.

View of windows
Visual connection of spaces and the interaction of the inside and outside is attractive for children.

Nature
Children are interested and its fantastic elements and like playing beside plants, flowers, animals, etc.

Inviting entrances
Walking paths and lines inside the site make children aware of entries, which is affected by the use of colours and glorious decorations.

Lighting
Natural daylighting and transparency have positive impacts on children.So corridors and even small or trivial spaces must enjoy daylighting to prevent scary scenes.

Comfort
The child's comfort results from the satisfaction of his/her need in the space.Therefore, children prefer classrooms with shelves and niches, windows protruding toward the outside nature, smooth flooring, comfortable sofas, wood furniture and soft sunlight.

Colourfulness
Children like bright and vibrant colours, striped patterns and bright spots.

Tabaeian The quantitative data and research findings, including questionnaires, are presented in Charts 1 to 4.
Chart 1.The frequency of existing school facilities (analysis result, 2017).
Chart 1 indicates that the schools lack spaces for free activity and creativity development of children (such as art workshops); on the other hand, the low frequency of playgrounds and sports courts suggests that the schools play a minor role in encouraging children to participate in sports activities.So, attention to spaces for children's leisure and sports games is preferable.
According to chart 2, the high percentage of time spent on playing together and the interest in music show the importance of the design of educationalrecreational space.Also, the lack of green spaces in schools for children's playing indicates that the impact of nature on the learning process of children is not noticed and must be a priority in design.
Chart 3 demonstrates that monochromatic spaces have the highest frequency, which indicates the effects of colours on the growth of children are neglected.

According to Chart 4, the professional workshops, green spaces and interaction with nature, life skills training and colour diversity in the area are the most critical factors in designing an educational-recreational space for mentally disabled children, respectively.

Design Solutions
Given the studies, field observations and parents' ideas, the following design solutions can be considered (see table 2).

CONCLUSION
The research has determined the useful criteria used to design an attractive and friendly environment for mentally disabled children.In addition to promoting the sense of safety and security in these spaces, it improves recreational activities of mentally disabled children both individually and collectively.
