Purpose: The study focussed on the effect of Abacus training on numerical ability (comprising of counting and mathematical operations) of children with hearing loss.

 

Method: 90 students with hearing loss were sampled from 6 special schools in Mumbai, India. A quasi- experimental study was employed using two group pre-test and post-test design. Data were collected using the Numerical Ability Test (NAT) as an instrument. Six null hypotheses based on the objectives were formulated and tested at 0.05 level of significance using t-Test - Assuming Equal Variances.

 

Results: The findings revealed that the experimental group which was instructed through Abacus showed higher proficiency in numerical ability as compared to the control group instructed through the conventional method. Gender as a variable seems to influence the mean achievement of numerical ability of students with hearing loss. While girls and boys did not differ in simple tasks such as counting, boys were found to be better in mathematical operations and overall numerical ability.

 

Conclusions: The Abacus teaching method results in higher mathematical achievements among students with hearing loss. Gender also plays an important role in mathematical learning, as evidenced by boys demonstrating more numerical ability than girls in the study sample.

Purpose: To develop a scale for the assessment of gross and fine motor skills of the children with mild and moderate intellectual disabilities so that their skills could be assessed and accordingly interventions in physical activities could be specifically designed for them.

 

Method: Thirty-eight items for the Test of Motor Proficiency scale was developed after initial try out, pilot study and final try-out by the researchers. Fifty children with mild intellectual disabilities (n = 26), and moderate intellectual disabilities (n = 24) aged between 6 to 17 years fulfilling inclusion and exclusion criteria were selected from special schools in Jammu district, J&K (India).The Test of Motor Proficiency was administered on the selected sample.

 

Results: Internal consistency as calculated through Cronbach's Alpha was .906, indicating very good reliability. There was a highly significant correlation between the two independent assessments in inter-rater reliability r (48) = .95, p< .05 and  also within the domains of motor proficiency, Visual-Motor control r (48) =.728, p< .05, Upper limb speed and dexterity r (48) = .98, p< .05 , Running speed and agility r (48) =.99, p< .05, Bilateral coordination   r (48) =.96, p< .05, Strength r (48) =.95, p<.05, upper limb coordination r (48) =.62, p< .05. Concurrent validity of Test of Motor Proficiency was established against BASIC- MR; the correlation of BASIC-MR (M = 151.92, SD = 18.08, N = 50) and Test of Motor Proficiency (M = 49.22, SD = 12.23, N = 50) was highly significant r (48) = .76, p< .05. The construct validity assessed through test retest was r (48) =.97, p< .05.

 

Implications: The Scale can be used in the assessment of gross and fine motor skills of children with mild and moderate intellectual disabilities for clinical and research purposes.
