An explorative investigation of the quality of items of the performance scales on the translated Sesotho version of the junior South African individual scales JSAIS (giq-8)Mawila, Daphney 25 November 2013 (has links)
M.Ed. (Educational Psychology) / This research inquiry employs the Rasch model of measurement to assess the contemporary quality of the items that constitute an intelligence test developed in South Africa during the 1980s. The Rasch model of measurement will be used as an analytical tool for exploring the quality of items constituting the performance scales of a translated version of the Junior South African Intelligence Scales (JSAIS). The JSAIS was translated into Sesotho and was used to assess grade 1 Sesotho home language learners. This study is part of the Soweto Panel Research Programme (SPRP), which aims to investigate the development of children in a specific Soweto school from preschool (grade R, age 5 and 6) to the end of the Foundation Phase (grade 3). Within this school, the research projects include the assessment of cognitive abilities, numeracy, literacy and the households of the children. I am involved in assessing the cognitive abilities of these children and work in collaboration with three Educational Psychology Master’s students from the University of Johannesburg. The cognitive abilities project aims to assess and track the cognitive development of young children from grade R to grade 3 over a period of four years. Cognitive development focuses on how children learn, process information and attain a veridical view of the world (Gopnik & Meltzoff, 1997), it entails the development of the thinking and organizing systems of the mind, and is composed of language, thinking, reasoning, problem solving, and memory development (Oakley, 2004).

An investigation of the quality of the test items on the numerical scales of the isiZulu translated version of the junior South African intelligence scales (JSAIS) (G-IQ8)Naicker, Aloshna 09 December 2013 (has links)
M.Ed. (Educational Psychology) / The picturesque landscape of South Africa is woven by the rich threads of diverse languages, cultures and beliefs. Despite the inherent differences of the different groups in this country, a common golden thread lies in the imparting of knowledge, values and beliefs from one generation to the next. This is often done formally, in the school environment, where children learn, develop and grow. The potential of children should be harnessed in an environment that is conducive to maximising the strengths and minimising their weaknesses. One domain is in the psychological testing arena where children’s cognitive abilities are assessed. The Junior South African Individual Scale (JSAIS) as an assessment measure is currently being used by psychologists despite the last norming having taken place in 1984 and the norms not being representative of the South African population. In an endeavour to transition from the past monolingual and monocultural practices, the JSAIS has been translated into isiZulu to eliminate any possible language barriers to participants. However, it is evident that translating tests is a risky procedure and every effort should be made to adhere to criteria proposed by the International Test Commission (ITC) to minimise cultural bias. One such way, is to thoroughly investigate the psychometric qualities of translated tests. The participants of the research are children in the Grade 1 isiZulu class at school in Soweto where research is being conducted. This longitudinal research project is a collaborative effort between the University of Basel, Switzerland and the Centre for Education Practice Research (CEPR) at the University of Johannesburg. The aim of this study was to apply a Rasch Analysis to the Numerical Intelligence Quotient Eight (NUM Scale) of an isiZulu translation of the Junior South African Individual Scales (JSAIS) to determine the quality of the items in relation to the ability of participants in the sample group. As an exploratory, quantitative study, the findings suggest that the JSAIS has some strong psychometric properties and that adaptation, translation and renorming of the test should be conducted in future studies. The findings of this study show that the data generated varied in its fit of the Rasch Model. While findings confirm that the numerical subtests of the Number and Quantity are valid measures of the construct for which it was designed, it is recommended that further studies be conducted into the equivalence of the isiZulu translated JSAIS, the further testing of larger samples of participants and the reduction of cultural loading on items. The information gleaned from this study regarding the misfitting of items, item difficulty and overlapping should also be considered to enhance the quality of this test and thereby maintaining the tenets of our new, modern democracy in South Africa.
