The validity of value-added measures in secondary schoolsScherman, Vanessa 19 September 2007 (has links)
The issue of quality education is a critical topic of discussion, for South Africa facing the challenge of implementation amidst a plethora of progressive policies. This research project is undertaken in collaboration with the Curriculum, Evaluation, and Management Centre (CEM) at Durham University in the United Kingdom. The Middle Years Information System (MidYIS) project was developed with the aim of providing schools with information on how learners would perform at the end of two national examinations namely Key Stage 3 and General Certificate in Secondary Education, in addition to providing value-added information. The purpose of the research reported here is to describe the procedures undertaken to explore the feasibility of implementing the MidYIS system in the South African context. The research was guided by two main research questions. The first research main research question is how appropriate is the Middle Years Information System (MidYIS) as a monitoring system in the South African context? The word “appropriate” here interrogates the suitability of the MidYIS system for South Africa looking specifically at validity and reliability issues. This non-experimental study used a mixed methods design, rooted in pragmatism, to explore validity and reliability issues of using MidYIS as a possible monitoring system that would provide a balanced view of the school’s contribution to academic gains made by learners. The sample included in the study ranged from National Department of Education officials (two officials from curriculum and assessment), Provincial Department of Education officials (one mathematics specialist, one language specialist and one specialist from the Gauteng Department of Education Office for Standards in Education), specialists in the field of language, mathematics, and psychology as well as 11 schools. In particular content-related validity (including curriculum validity), construct-related validity, and predictive validity were examined while inferences drawn with regard to reliability were done by means of internal consistency reliability. From a curriculum perspective for content-related validity, it was found that there was moderate curriculum validity for language while inferences drawn for mathematics were substantially stronger. For content-related validity from a psychometric perspective, it was found that there was overlap between the domain of developed abilities and the MidYIS assessment. Construct-related validity was explored by means of Rasch analysis and it was found that items in the MidYIS assessment tend to form well-defined constructs. Predictive validity was explored by means of correlation analysis between the MidYIS assessment and school-based results in language and mathematics. The analysis shows that it could be possible to use the MidYIS assessment for prediction purposes. However, additional research would be needed to explore this facet of validity further with a larger sample and using standardised school-based results. The MidYIS assessment was found to be reliable for the sample as a whole as well as for population groups within the sample. The second main research question extends the first research question. If MidYIS is valid, with South African adaptations, and reliable, then what factors on a school, classroom, and learner-level could have an effect on learner performance. Thus, the second main research question is which factors could have an effect on learner performance and therefore inform the design of the monitoring system? In order to explore factors, multilevel analysis was undertaken on the various levels within the school system namely the principals, mathematics and language educators, as well as learners who completed questionnaires. It was found that four learner-level factors (with whom learners live, mother’s level of education, importance of mathematics and importance of English), one educator level factor (challenges to assessment due to lack of in-service training) and two school-level factors (educators make use of monitoring systems and encouraging academic achievement) seem to have an effect on the performance of learners. / Thesis (PhD (Assessment and Quality Assurance in Education and Training))--University of Pretoria, 2007. / Curriculum Studies / PhD / Unrestricted

Predictive validity of a selection battery for technikon studentsVan der Merwe, Doret 30 November 2003 (has links)
Student selection is particularly challenging in South Africa. Heterogeneous educational backgrounds require that it is necessary to assess prospective students' potential rather than their current abilities that crystallised from inadequate school education. Dynamic assessment assesses learning potential versus traditional psychometric measures, which are static measures of cognitive ability, measuring what a person has already learned.
The aim was to determine the predictive validity of a selection battery. The following predictors were included in the study; matric results, Potential Index Battery, LPCAT, bridging course status and gender. The results confirmed that static measures of intelligence and matric results showed lower predictive validity than learning potential tests. The learning potential measure appeared to be a more valid predictor of academic performance and is suitable to include in a selection battery. Gender and bridging course factors did not reflect significant differences in academic performance. There were indications that students perform better in successive years of study, once they have adjusted to tertiary education. / Industrial and Organisational Psychology / M. Comm.

Gestruktureerde onderhoud as voorspeller van opleidingsukses vir bestuursdienstepraktisyns / The structured interview as predictor of training success for management services practitionersCrous, Charl Jacobus 11 1900 (has links)
Die doel van hierdie ondersoek is om die gestruktureerde onderhoud, in die vorm van die
Targeted Selection Interview tegniek, as geldige keuringsinstrument ter voorspelling van
opleidingsukses van bestuursdienstepraktisyns in die Suid-Afrikaanse Polisiediens te
ondersoek. Daar is gebruik gemaak van 'n opnamemetode en die opleidingsprestasie van
kandidaatbestuursdienstepraktisyns is vergelyk met die resultate wat kandiddate behaal het
in hulle evaluering tydens die gestruktureerde onderhoud. Korrelasies is bereken tussen die
tellings behaal vir elke dimensie wat die onderhoud evalueer en die tellings onderskeidelik
behaal vir elke opleidingsmodule voltooi tydens die 1 0-weke-bestuurs-dienstesertifikaatkursus
wat aangebied word deur die Technikon Pretoria. Die resultate behaal in die
ondersoek dui op lae, nie-beduidende korrelasies tussen die gestruktureerde onderhoud as
keuringsinstrument en die kandidaatbestuursdienstepraktisyns se prestasie tydens opleiding.
Die resultate dui dus daarop dat die Targeted Selection Interview wat die Suid-Afrikaanse
Polisiediens toepas, nie opleidingsprestasie voldoende voorspel nie. / The aim of this study is to investigate the validity of the structured interview, in the form
of the Targeted Selection Interview technique to predict training success of management
services practitioners in the South African Police Service. A survey method has been used
to obtain the data regarding the training success of candidates and the evaluation results of
the structured interview. The correlation was calculated between scores obtained for every
dimension measured by the interview and the scores for every training module compl~ted
on the 1 0-week management services certificate course, presented by the Technikon
Pretoria. The results obtained indicates low, insignificant correlations between the
structured interview as selection instrument and the training results of candidate
Management Services practitioners. The results thus indicate that the Targeted Selection
Interview as applied by the South African Police Service, does not sufficiently predict
training success. / Industrial and Organisational Psychology / M.A. (Bedryfsielkunde)

The predictive validity of the selection battery for trainee pilots in the South African Air ForceFlotman, Aden-Paul 30 June 2002 (has links)
The sample comprised 92 candidates who have completed the Ground School Phase of
the trainee pilot training programme. The independent variables are Raven's Advanced
Progressive Matrices Test, the Blox Test and the Vienna Determination Test. The
dependent variable is the candidates' results after the Ground School Phase of their
training. The results indicated that only the Advanced Ravens test and the Vienna
Determination test (Phase 3} correlate positively with the Ground School Phase results
of the candidates.
The current battery emphasises cognitive abilities and psycho-motor functioning and does
not cover personality traits of prospective candidates. It is recommended that new
instruments are included (to cover the measurement of personality traits), that the sample
size should be increased by promoting pilot training among previously disadvantaged
students and that the current pilot profile should be updated as a matter of urgency. / Industrial and Organisational Psychology / M.A. (Industrial Psychology)

The predictive validity of learning potential and English language proficiency for work performance of candidate engineersMphokane, Adelaide 06 1900 (has links)
The aim of this research was (1) to provide empirical data of learning potential and English language proficiency for work performance; (2) to establish whether race and gender influence work performance; (3) to evaluate practical utility and to propose recommendations for selection purposes. The Learning Potential Computerised Adaptive Test and the English Literacy Skills Assessment were used as measuring instruments to measure learning potential and English language proficiency respectively. Work performance data were obtained from the normal performance data system of the company where the research was conducted. ANOVA results showed differences between race and gender groupings. A regression analysis confirmed the predictive validity of learning potential and English language proficiency on work performance. The Spearman rho correlation coefficient (p < 0.05) showed a significant positive correlation between the investigated variables / Industrial and Organisational Psychology / M. A.

L’évaluation du risque de récidive des agresseurs sexuels : vers une approche centrée sur les construits psychologiquesBrouillette-Alarie, Sébastien 08 1900 (has links)
Cette thèse a été faite sous la tutelle de Jean Proulx et R. Karl Hanson. Elle a évaluée par un jury composé de Franca Cortoni, Jean Proulx, R. Karl Hanson, Jean-Pierre Guay et Howard E. Barbaree. Suite à la soutenance, la thèse a reçu la mention "exceptionnelle", a été recommandée à la liste d'honneur du doyen et a été soumise pour le prix de la meilleure thèse de la FESP 2017. / Les outils actuariels servant à évaluer le risque de récidive criminelle des agresseurs sexuels ont souvent été critiqués pour leurs fondements « athéoriques ». En effet, ces derniers ont été constitués en rassemblant les caractéristiques les plus fortement associées à la récidive, sans qu’une théorie ne les unisse à priori. Si cette méthode a assuré une bonne validité prédictive à ces instruments, elle leur a insufflé très peu de résonnance clinique; plusieurs professionnels n’y voient qu’une liste de corrélats statistiques vides de sens. La présente thèse a entrepris de relativiser ces critiques en appliquant des modèles de facteurs latents aux différents items des outils actuariels. Les modèles de facteurs latents postulent que les comportements manifestes (observables) d’un individu renseignent sur ses caractéristiques psychologiques latentes (non observables) – de la même manière que les symptômes d’une maladie permettent d’inférer sa présence chez un patient. Puisque les items des outils actuariels correspondent à divers comportements ou caractéristiques criminogènes manifestes, il devrait être possible de les rassembler en dimensions pour identifier les principaux construits psychologiques latents associés à la récidive des agresseurs sexuels. Les articles de la présente thèse ont donc proposé d’identifier les dimensions de la Statique-99R et de la Statique-2002R, la famille d’outils actuariels pour agresseurs sexuels la plus utilisée mondialement. Trois dimensions ont été extraites par analyse factorielle : 1) la persistance dans les délits sexuels/paraphilies sexuelles, 2) la délinquance générale et 3) le jeune âge/victimes sexuelles non familières. La première dimension était exclusivement associée à la récidive sexuelle, tandis que les deux dernières étaient associées à tous les types de récidives. Leur validité convergente a ensuite été explorée afin d’évaluer à quelles caractéristiques psychologiques ces dernières référaient. La persistance/paraphilie a convergé avec des indicateurs d’intérêts sexuels déviants non coercitifs, alors que la délinquance générale a convergé avec une constellation de traits antisociaux. Finalement, le jeune âge/victimes sexuelles non familières a convergé avec l’intention claire de blesser ses victimes. Ces résultats ont mené au développement d’un modèle tridimensionnel du risque de récidive des agresseurs sexuels ayant plusieurs implications pratiques pour le domaine. D’une part, les outils actuariels gagneraient à utiliser des scores dimensionnels plutôt que des scores totaux. Par exemple, en retirant la dimension de persistance/paraphilie de la Statique-99R/2002R, il est possible de prédire efficacement la récidive violente non sexuelle et non sexuelle non violente des agresseurs sexuels, ce que l’instrument ne permettait pas précédemment. D’autre part, la connaissance des grandes dimensions de facteurs de risque est susceptible d’aider les évaluateurs à choisir et intégrer plusieurs mesures actuarielles. Cela se révèle particulièrement pertinent lorsque deux mesures du risque divergent, malgré qu’elles aient été conçues pour la même population. Finalement, nos résultats indiquent que les facteurs de risque statiques sont susceptibles de renseigner (imparfaitement) la pratique clinique quant aux besoins criminogènes des agresseurs sexuels. Bien que nous ne suggérions aucunement de substituer cette pratique à la cotation d’outils actuariels de troisième génération, elle pourrait se révéler pertinente pour les établissements n’ayant pas les ressources nécessaires pour coter de tels instruments. Au plan théorique, le modèle tridimensionnel comporte plusieurs avantages par rapport aux modèles à deux dimensions, traditionnellement constitués de la déviance sexuelle et de la délinquance générale/psychopathie (ex. : Doren, 2004). D’une part, les données empiriques supportent clairement la présence de trois dimensions du risque de récidive des agresseurs sexuels, et non deux. D’autre part, la troisième dimension permet d’intégrer une nuance importante au modèle, soit la distinction entre les intérêts sexuels déviants par leur objet de désir (ex. : pédophilie) et les intérêts sexuels déviants par leur aspect coercitif (ex. : sadisme sexuel). Cette distinction est primordiale, dans la mesure où ces intérêts sexuels ne prédisent pas les mêmes types de récidives. Finalement, notre modèle s’intègre au modèle étiologique du risque de Beech et Ward (2004), qui, lorsque complètement validé, pourra donner lieu à des efforts de prévention – une denrée rare dans le domaine. / Actuarial scales for the prediction of sexual violence have been criticised because they are purely based on atheoretical correlates. Therefore, they are unlikely to provide clinical and theoretical insight on the psychological traits and mechanisms that underlie criminal recidivism. However, according to latent variable models commonly used in psychology, patterns of behavior, thought, and emotion are caused by latent psychological constructs, such as extraversion and neuroticism. Because static and stable risk factors in actuarial scales are mostly behavioral, it should be possible to use them to infer the major psychological constructs responsible for recidivism risk. The current thesis applied latent variable models to nonredundant items from the Static-99R and Static-2002R, the two most commonly used risk tools for sexual offenders. Three dimensions were identified: 1) persistence in sexual crimes/paraphilia, 2) general criminality, and 3) youthful stranger aggression. To understand the psychological meaning of these dimensions, convergent and predictive validity analyses were conducted. Results indicated that persistence/paraphilia was related to dysregulation of sexuality towards atypical objects, without intent to harm, while general criminality was related to antisocial traits. Finally, youthful stranger aggression was related to a clear intent to harm victims. All three constructs predicted sexual recidivism with similar accuracy, but only general criminality and youthful stranger aggression predicted nonsexual recidivism. These results suggest that a tridimensional model of sexual offender risk is viable. That model has numerous practical implications. First, actuarial scales should sort items by constructs rather than rely on total scores. Total scores focus the predictive utility of risk scales to the specific outcome for which they were developed (usually sexual recidivism). When constructs are known, it is possible to improve the prediction of other outcomes by removing constructs unrelated to each of these new outcomes (e.g., removing sexual criminality items to improve the prediction of nonsexual recidivism). Second, construct-level approaches facilitate the integration of potentially conflicting risk scales. By understanding the constructs assessed by each scale, an evaluator can deduce which measures should be combined, and which should not. Finally, static risk constructs significantly correlate with psychological features that are found in dynamic risk scales. Consequently, scales composed entirely of static risk factors could – albeit imperfectly – inform the treatment needs of sexual offenders. These results could assist settings lacking the resources to implement dynamic risk tools. The tridimensional model also has theoretical implications. First, our model showed better statistical fit than classical two factor models based on sexual deviance and psychopathy (e.g., Doren, 2004), suggesting that there are more than two substantive dimensions related to sexual offender recidivism risk. Second, the presence of a third factor enabled an important distinction between noncoercive (e.g., fixated pedophilia) and coercive (e.g., sexual sadism) deviant sexual interests. Such a distinction is particularly relevant in the field of risk assessment, because they do not predict the same types of recidivism. Finally, our model can be integrated in Beech and Ward’s (2004) etiological model of risk, which, once fully validated, could enable primary and secondary prevention efforts.
