A study to evaluate the effectiveness of self instructional module regarding learning disabilities of primary school children among primary school teachers of selected schools at Appakudal, Erode District.

Today’s children are tomorrow’s citizens. They are in a continuous process of growth and development. Any alteration in its course lead to development disorders of learning disability plays a significant role as a silent handicap among children. It is estimated that 4-5% of students in school have learning disability. Learning Disability is “a study to evaluate the effectiveness of self instructional module regarding learning disabilities of primary school children among primary school teachers of selected school at Appakudal, Erode district”. As there are no specific test to identify children with learning disability, health professionals have to rely mainly on teacher’s report for its diagnosis. Previous studies have proved that teacher’s towards such children have great influence towards their recovery. OBJECTIVES OF THE STUDY: 1. To assess the pretest and post test knowledge of experimental and control group of teachers regarding learning disabilities. 2. To compare the pretest and post test knowledge of experimental and control group of teachers regarding learning disabilities. 3. To compare the posttest knowledge of experimental and control group of teacher regarding learning disabilities. 4. To findout significant association between knowledge of experimental and control group of primary school teachers and selected demographic variables regarding learning disabilities. METHODOLOGY: The research design adopted for this study was quasi experimental design and research approach adopted for this was to evaluative the educative approach. The sample size was 60 teachers. In this, 30 teachers were selected for experimental group and 30 for control group by purposive sampling method. Teachers were selected in selected schools at Erode District. Data was collected by using structured questionnaire, this consists of two sections. Section I – Demographic variables Section II – Questionnaire regarding knowledge. RESULT: The finding of the experimental group of teachers pre test knowledge and mean score was 16.6 (41.50%) and level of knowledge was inadequate. In post test knowledge score was 33.3 (83.25%). Now the level of knowledge was adequate in experimental group. Similarly in the control group pretest knowledge mean score was 17.2 (43.00%) and post test knowledge mean score was 19.1 (47.75%). In the comparison of experimental group and control group. In the pretest there is no significance difference between the experimental and control group but after self instruction module it is observed significant difference between experimental and control group. Teachers gained knowledge above 41.75% more knowledge on learning disabilities after administration of self instruction module. This 41.75% of knowledge gain is the net benefit of this study which indicates the effectiveness of self instructional module learning disabilities in experimental group than control groups. The student independent ‘t’ test and chi square shows there was significant association between post test knowledge score and selected demographic variables in experimental group like age and experience of teachers than control group. CONCLUSION The findings of the study was need of pediatric nurse to conduct training programme regarding learning disabilities among the primary school teachers. The study revealed theta the level of knowledge regarding learning disability was low among school teachers in control group. The concluded that need for providing knowledge on learning disability is an important strategy to utilize teachers as effective contributors towards child health services

Spray deposition and characterization of nanostructured Li doped NiO thin films for application in dye-sensitized solar cells

Transparent conducting Li (0–5 wt%) doped NiO thin films with preferential growth along the (111) plane were deposited onto glass substrates by pyrolytic decomposition of nickel nitrate and lithium chloride precursors at 500 ◦C in air. The effect of Li concentration on the structural, optical and transport properties of NiO thin films was studied by x-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), spectral transmittance, photoluminescence and linear four-probe resistivity. Activation energies as a function of Li concentration were deduced from the temperature dependent resistivity data measured in the range 300–448 K. The figure of merit was deduced by combining the spectral transmittance and sheet resistance values. The variation in properties of NiO thin film due to Li doping are discussed based on the above results. A dye-sensitized solar cell has also been fabricated for the optimized Li doped NiO thin film and the results are presented
