An assessment procedure to measure the learning potential of mildly and moderately mentally handicapped adults was investigated in this study. The procedure was developed to overcome the limitations of previously established learning potential assessment procedures by meeting the specific orientation necessary when assessing the mentally handicapped, by avoiding practice and mechanical memory effects, and by requiring the subjects to show the ability to retain and apply new cognitive skills. Thirty institutionalized mentally handicapped adults were matched on IG and then randomly assigned to an assessment or control group. For the assessment group the intervention procedure involved the Coloured Progressive Matrices test as a pretest measure, in four treatment sessions each two to three days apart, and as a posttest measure. Verbal and/or figural aids were provided when an incorrect response was given on a test item during the treatment sessions. The control group was provided the same number of administrations of the test but without the treatment intervention. Significant differences were found between the pre and post test performance levels of the assessment group. The control group showed no significant gains. The learning potential assessment procedure used in this study provided a measure of the learning potential of mentally handicapped institutionalized adults.The results indicate that the mentally handicapped can perform at much higher levels than those assessed by standardly used intellectual measures. Implications are that through the use of this approach a clearer discrimination of intellectual ability within the broad classifications of the mentally handicappped can be gained. Such information could be used to aid in the selection of peers, developmental programming decisions, and provide prescriptive information about the most efficacious modes of learning for an individual.

This study investigated the effectiveness of Feuerstein’s mediated intervention programme on a sample of the Grade Five population, in a remedial school. The participants (n=20) were systematically sampled and they constituted two groups, namely, Individual Mediation (n=10) and Group Mediation (n=10). It was hypothesised that participants exposed to this programme would yield significant improvement in cognitive functioning as measured by the (Raven’s Coloured Progressive Matrices (RCPM). As a result of the intensity and the duration of the mediation that was provided to the participants within the Individual Mediation, it was hypothesised that they would perform significantly better than those within the Group Mediation. Set Variations B-8 to B-12 from Feuerstein’s Learning Potential Assessment Device served as vehicle for mediating cognitive deficiencies. Following the intervention, a significant improvement on the RCPM was only obtained within the Individual Mediation. Although there was significant improvement, no significant difference was found between the Individual Mediation and the Group Mediation. The pre-post-test results of the Individual Mediation corroborate existing literature that provision of adequate and appropriate mediated learning experience is effective in improving cognitive functioning. However, non-significant results between the two groups suggest that a pre-post significant finding within the Individual Mediation was as an effect of pre-test differences. These findings are therefore inconclusive. It might be helpful to further replicate this investigation in order to determine whether support is found for the previous or for the present findings.

The purpose of the study is to assess whether a psychological test of learning potential can predict supervisory rating of different components of learning potential for the low level worker-This exercise would be done ascertain the relationship between the learning potential by using the TRAM-2 battery Ca learning potential assessment instrument) and supervisory rating of the sample of workers. A sample of 60 employees with levels of education ranging form grade 8 to 12 inclusive was used. It is hoped that the findings would predict or identify employees with potential for development which would then lead to planning how that potential is developed to, empower the employees to improve their performance and self actualise their objectives. This would enhance the realisation of aims and objective of skills development and employment equity plan of the company. The findings and their implications and suggestions would be discussed in this study. / Thesis (M.Com.)-University of Durban-Westville, 2003.

South African research into dynamic assessment has contributed to the growing body of international research which supports the efficacy of dynamic assessment in uncovering learning capacity in a variety of populations of learners with special needs. This study investigated the application of dynamic assessment to a sample of black children within a South African township clinic setting. Aged 9-15 years (mean age = 10.96) they had been referred to the clinic with learning difficulties. The experimental group (n=48) was exposed to a group dynamic assessment process, using certain tasks of the Learning Propensity Assessment Device (LPAD). Their performance was assessed prior to and following the mediated learning intervention. Using Analysis of Covariance, comparisons of pre and post-test scores combined with an innovative qualitative scoring method designed by Lurie and Kozulin (1996) yielded positive findings for the experimental group as compared with a control (n=24) not exposed to mediation. Results of the Raven's Coloured Progressive Matrices (RCPM) and the Rey-Osterreith Complex Figure Test (ROCFT), suggest that the intervention yielded changes, not only in the scores attained, but also in the quality of the responses on the post-tests.
