Review of literature



                                                  CHAPTER-2
                                 REVIEWS OF LITERATURE
Review of related study plays an important role to understand deeply the problem understand investigation. Related studies are available in journals, research survey and in books.
MEANING OF REVIEW
The accumulated knowledge of the past provides the bases on which the edifice on new knowledge is to be erected. The phase ‘Review of Literature’ consist of words viz. ‘review’ and ‘literature’.
The term ‘review’ means to organize to evolve an edifice of knowledge to show that this study would be an addition to this feild.
The term ‘literature’ refers to the knowledge of the particular area of the individual of any discipline , which include theoretical, practical and its research studies.
Thus review of related literature gives the researcher an understanding of the research methodology, which refers to the way the study is to be conducted.
Best (1983) says, “practically all human knowledge can be found in books and libraries unlike another animals that must start anew with each generation, man build upon the accumulated and recorded knowledge of the past”.
The related literature in any field form that foundation upon which all the future work will be built. It makes the investigator aware of what has already been done in the field, what are the finding and what is being done thereby, insuring the avoidance of unnecessary duplication.
The review of related literature is an essentially preliminary step, which must be taken in research. Review of related studies gives the invigilator the insight to tackle the research problem. The literature provide as a guide to the researcher in locating, selecting, utilizing primary and secondary source of information.
 This review of related literature helps the investigator:-
·        To define the limits of his fields. It helps the researcher to delimit and define his problem.
·        To avoid unintentional duplication of well-established findings.
·        To know about the tools and instruments which, proved to be useful and promising in the previous studies.
·        In speculating useful hypothesis and to provide suggestions for significant investigation.
·        To become aware of the status of the problem.
·        To formulate an appropriate research design.
·        To locate the source of date and to collect the pertinent data useful in the interpretation of results.   
2.1 STUDIES RELATED TO LEARNING DISABILITY:-
Bhattacharya (1982) conducted a study on Diagnosing and preventing learning disabilities of primary school students in Arithmetic. To diagnose and prevent learning disabilities in arithmetic of primary school. There are 40 samples of students having learning difficulties in reference to mathematics of 10 primary schools. It was found that learning through audio-visual methods caused prolonged retention than traditional methods.
Wilson (1998) investigated the ability of general education middle school students to prompt and reinforce skill acquisition of peers with moderate to severe disabilities in the context of content area co-operative learning instructional settings. The above study consisted of 22 students of general education middle school students. The strategies with prompt and reinforce skill acquisition were used for the study. Results indicated that the general education students learned to provide the identified opportunities, reinforcement and prompt sequence to their peers with learning disabilities. The tutors and tutees felt positive towards their participation.
Arya (1997) designed to estimate the prevalence of disability and impairments among pre- school children in rural areas and to discover the significant socio demographic variables which influence such prevalence rates. The distribution among different age groups appeared to be positive on screening. In relation to sex variables, there was generally higher prevalence of all disabilities. It was found that there existed a greater prevalence of handicaps among lower socio- economic status groups such as scheduled castes, scheduled tribes and backward classes than among the other groups.
Wilson and David (1994) evaluated the academic intrinsic motivation and attitudes towards schools and learning of learning disabled students. The study revealed that subjects perceived the school environment and academic tasks as two separate factors. Learning disabled students, compared to non-disabled students, exhibited more positive attitudes towards the school environment than for academic learning tasks. School attitudes improved as grade level increased.
Carlisle and Andrews (1993) in their study tried to find out how mainstreamed learning disabled students cope up with their science classes. This study found that mainstreamed fourth and sixth grade students with learning disabilities had significant weaknesses on a science curriculum based assessment relative to non-disabled peers and they rated
themselves and were rated by their teachers more negatively.
Swanson (1993) conducted a study on the information processing analysis of learning disabled children. The sample for the study consisted of 32 learning disabled, 17 gifted and 14 normally achieving students from grade 4 and 5.Results reveal that learning-disabled children’s problem-solving performance reflects a weak integration of meta cognitive skills with online processing and problem solution
Lorsbach and Frymier (1992) made a comparison of learning disabled and non-disabled students on five at-risk factors, viz. Personal pain, family socio-economic status, family instability, family tragedy and academic risk. This study compared 1,356 students with learning disabilities and 17,431 non-disabled students in grades 4, 7 and 10 on risk factors and number of school interventions. The study found that learning- disabled children were significantly more at risk on personal pain, family socio-economic status, family instability, family tragedy and academic risk.
Coleman (1992) compared the similarities in the social competencies of learning disabled and low achieving elementary school children. Eighty-five children with learning disabilities in grades 3-6 were compared to match low achieving (LA) peers. Results indicated that the two groups were comparable on most social competence measures, although LD children reported themselves less lonely than LA children, and regular class children rated LD children more likable than LA children.
Anima(1990) did research on learning disabilities in the reasoning power of the student in geometry, he took sample of 148 students covering both the gender and belonging to both the rural and urban areas. The study was conducted using a diagnostic test of attainment and teaching strategy. Major finding were through audio visual material caused more prolonged retention then through the conventional method.
Bays (2001) presented a grounded theory and describe how the supervision of special education instruction occurs in public elementary schools in rural setting. Nine elementary schools in three rural districts in the State o f Virginia participated in this study. Interview data was collected from 34 participants including special and general education teachers, principals and directors of special education. The grounded theory suggests that the supervisor’ role is assigned to the principal: (i) Monitoring for legal compliance supervision of instruction for students of disability, and (ii) Evaluation of teachers supervision. The outcome of negotiating competing priorities and contextual factors is a dispersal of responsibility for supervision to three groups of educators. Principal as a primary supervisor: utilizes three strategies to address supervision: the observation evaluation process (ii) supervision by disability and class. Their separate legal development doesn’t constitute an institutional conflict. Result indicated that for the most part the political discord among rights struggle on the basis of race, sex disability and class has entailed a contest for political movement energies and for political attention of particular legal rights conceptions. At the same time educational rights on the basis of socioeconomic class founded upon particular legal form of material resource equalization evidence the potential to develop in the basic institutional coherence with right on the basis of race 33 as well as sex and disability. By contrast the school choice movement in the form of charter and voucher school legislation actually with those on the basis of race, sex and disability. Individual must in effect choose between the concrete, legal attainment of such rights versus those on the basis of race, sex and disability.
James and Deborah (2002) conducted a study on classroom behaviour and the academic progress of learning disabled students. A total of 43 learning disabled (LD) students who were identified in grades 1-3 were followed up in their second year of special education services. Teachers completed the Classroom Behaviour Inventory (CBI) for each LD student and for randomly selected classmates, and both groups of students were observed with the SCAN system in regular classroom settings. Group difference in teacher perceived task orientation, independence, and verbal expressiveness replicated previous findings with CBI for this LD sample. SCAN observations partially replicated previous results in that LD children interacted with teachers more often than classmates. Multiple regression analysis indicated that both measures of behaviour were predictive of reading achievement during year 1 when the LD children were identified and that the CBI predicted academic progress from one year to the next. Result indicated that both teacher ratings and observational evidence converged on the importance of task –oriented behaviour, independent functioning, and socially appropriate behaviour in understanding the poor achievement of LD students.
 Bayer (2003) conducted a study on a descriptive study of teaching strategies used by general education teacher in classroom including student with mild learning disabilities. This study focused on teaching strategies and methodologies successful in general education teacher in grade four through six used in teaching mathematics within an inclusive setting. This study also focused on the rational of how teacher ensure that special education has the opportunity to engage in successful learning experience during mathematics instruction by using ongoing and continuous assessment. The study included how student with learning disabilities benefited from an inclusive setting and how teachers’ choice of specific instruction strategies were based on individual student needs. The result can offer assistance to teacher who a restruggling to implement such strategies.
Kenneth and Mark (2004) examined social skills interventions for individuals with learning disabilities. The purpose of the study was to examine the need and effectiveness of social skills interventions. 65 learning disabled children participated in the study for examining the social skills interventions for individual with learning disabilities. Result laid stress that social skill deficits have become a primary target for remediation and there is great need of training program and interventions activity for student with learning disabilities.
Fontenot (2005) examined the attitudes of rural, suburban and urban public elementary school principals in Texas regarding the inclusion of students with disabilities into the general education classrooms. A three point questionnaire, the “Modified Principles” and inclusion survey, was sent to 733 randomly selected principals, requesting information that could be used to evaluate attitudes toward inclusion of students into the general education classroom setting. There was no significant correlation found between age and attitudes, nor gender and attitudes of principals toward inclusion of students with disabilities. Although a negative correlation was found between full time regular educations teaching experiences in regard to the attitude score of principles toward inclusion of students with disabilities. Neither general education teaching experience nor special education teaching experience was significantly correlated with attitude.
Carlson (2005) in his study described the history of learning disabilities and intervention theories, which might be helpful for adult college students suffering from many other learning disabilities Learning disability is not longer considered as a form of mental retardation. It is related to some typical brain dysfunction.
Mehta (2006) in his study revealed that there is a significant difference in the awareness of learning disabilities in teachers of different boards such as SSLC, CBSE, ICSE. Among the boards ICSE board teachers were more aware about learning disabilities as compared to CBSE and SSLC board.
Kulkarni and Karande (2007) examined educational provision and learning disability. The objective of the study was to assess the impact of the provision of the Maharashtra Govt. on the academic performance of children with learning disabilities at the secondary school certificate board examination. The study was conducted in Maharashtra with 12-18 years old girl. Three governments were selected at random. Thirty 12-18 years old girls were selected from each school on the basis of their academic performance. The result shows that there was as significant improvement in their academic performance at the SSC board examination.
Erik (2010) examined the summer employment and community activities of 136 high school students with severe disabilities. The majority of youth was either not working (61.7%) or reported sheltered employment (11.1%) The most prominent predictors of summer employment status were holding a job during the spring semester and teacher expectations for employment. Recommendations for research and practice focus on increasing the capacity of schools, families and communities to support the involvement of youth with severe disabilities in meaningful summer activities.
Anette (2010)Conducted a study on learning difficulties and academic competence among children with and without learning disabilities. The aim of this study was to examine learning difficulties as well as academic competence. The sample consisted of 30 learning disabled children. These children were examined for the learning difficulties and academic competence and experimental study was carried out. Result was interpreted as indicating that children with learning disabilities have low academic competence and need special assistance.
 Benjamin J. Lovett(2010)  conducted a study on extended time testing accommodations for students with disabilities- answers to five fundamental questions . This study reviews a wide variety of empirical evidence to draw conclusions about the appropriateness of extended time accommodations. The evidence reviewed raises concerns with the way that extended time accommodations are currently provided, although the same literature also points to potential solutions and best practices.
Verma (2011) Learning disabled (N = 36) were identified from among the 160 discrepant achievers, screened from 1140 male students belonging to 3 rd , 4th and 5th grade levels of three English medium schools located in western sub-urban of Mumbai. Standard scores and regression methods were used to compute aptitude-achievement discrepancy. The discrepant achievers were subjected to rating, on BCSLD, by their teachers; those scoring at or above 75th percentile were further administered WISC III. Of these, who scored P > V at least by 12 to 15 points was designated learning disabled (L D). LD (N = 36) were randomly assigned, to experimental and control groups (N = 18, each group). The experimental group was exposed to treatment whereas the control group received none. But they did take pre-test and all the post-tests. First round of treatment was given for 15 days followed by post-test (O1 ). Quite a few did not reach the criterion. Hence a second course of treatment was given followed by post-test (O2). A third post-test (O3) was done after a blank period of next 15 days, to test persistence of gain scores. 2 × 4 repeated measures ANOVA and paired t test revealed that CBM based strategy training did not prove effective in remediating perceptual deficit of auditory and visual discrimination among LD sample. But the time input in treating figure-ground deficit was observed to be partially beneficial.
Ryan (2011) investigated the barriers facing students with disabilities in nursing courses, in particular in clinical placements. Results showed that a lack of understanding of legislative and institutional requirements underlies negative attitudes about students with disabilities, especially in practicum-based courses.
Noona Kiuru et al. ( 2011) conducted a study  on students with reading and spelling disabilities, peer groups and educational attainment in secondary education, to investigate whether the members of adolescents’ peer groups are similar in reading and spelling disabilities and whether this similarity contributes to subsequent school achievement and educational attainment.
Kunhiraman (2011) conducted a study to identify learning disabilities of primary school children in Kerala with special reference to reading and writing. Normative survey method was adopted for collecting data for the study. The sample constituted 630 primary school children of Kerala (from classes– 4, 5 and 6) selected on the basis of ‘stratified random sampling’. The tool include(1)learning disabilities test battery-sub test on reading and writing(2)raven’s coloured progressive matrices test. The data collected were analysed using appropriate statistical measures. It is revealed that 10% of the samples were with reading and writing disabilities.
Bane et al. (2012) explored the perspectives of people with learning disabilities on relationships and supports in the Republic of Ireland. A national research network consisting of 21 researchers with learning disabilities, 12supporters and 7 university researchers conducted the study. Findings suggested that people with learning disabilities have a diversity of experiences and views on relationships and support needed to keep them. People with learning disabilities taking part in the focus groups identified that they need more support from friends, family, and services staff to develop new relationships and keep their existing ones.
