2	The effect of mode of test administration on computerised assessment results using proctored and unproctored test administration procedures Nel, Francina Helena 02 October 2013 (has links) The purpose of this research was to investigate the effect that mode of test administration could have on computerised assessment results involving proctored and unproctored test conditions. Two South African test instruments, the Learning Potential Computerised Adaptive Test (LPCAT) and the Career Preference Computerised Adaptive Test (CPCAT) were used in the study. A quantitative, quasi-experimental design was used, and a convenience sample for LPCAT (N=82) and CPCAT (N=81) consisted of employees in the hospitality industry. Using a within-participants design, the dependent t-test was used for statistical analysis. For the total group the LPCAT results yielded no statistically significant differences between the mean scores for the two different modes of administration. For the total group the CPCAT results yielded statistically significant differences in the mean scores per mode of administration for five out of 34 dimensions, however, for the majority of the CPCAT sub-dimensions, the mode of administration did not impact on results. It was concluded that mode of administration did not impact on the cognitive test scores and only to a very limited degree on the non-cognitive test scores. Based on the results the null hypotheses for the effect of mode of administration were not rejected. / Industrial & Organisational Psychology / M.A. (Industrial and Organisational Psychology) Computer adaptive testing CPCAT Internet-based testing LPCAT Mode of administration Proctored Unproctored Dependent t-test 150.2870285 Psychometrics Psychology, Industrial Computer adaptive testing Web-based instruction Psychological tests -- Data processing t-tests (Statistics)
3	The relationship between learning potential, English language proficiency and work-related training test results Schoeman, Adele 11 1900 (has links) Continuous change and competition in the working environment necessitate increased efficiency and productivity which require different and enhanced skills and abilities. It is therefore important that the right people with the right skills are selected and employees are developed to enable them to meet the organisational and national demands of the future. This dissertation investigates the relationship between learning potential, English language proficiency and work-related training test results to establish why some production employees perform better on work-related training test results than others. The results indicate that there is no significant relationship between the work-related training test results and either learning potential or English language proficiency. There is, however, a significant correlation between learning potential and English language proficiency. It might be worthwhile exploring the availability and adequacy of assessors as well as the motivational level of the production employees as factors that influence the progress made with work-related training test results. / Industrial and Organisational Psychology / MCOM (Industrial Psychology) Learning potential Psychometric testing English language proficiency Training test performance Intelligence testing Work related training Adult learning Learning ability Psychological tests English language -- Ability testing Employees -- Training of -- South Africa
