A model for enhancing volitional strategies' use and mathematics achievement in grade 9 in a rural community school / David Lehlohonolo MolokoliMolokoli, David Lehlohonolo January 2014 (has links)
The contextual factors that affect effective Mathematics learner engagement patterns are due to lack of self-regulated learning and enthusiastic volitional use. An active role for Mathematics learners incorporates use of volitional strategies towards knowledge construction. Self-regulated learning is an important factor for effective learning. However the PISA (2004) survey noted the problem of deficits in cross-curricular academic competencies, which included general self-regulatory strategies. The continued poor performance of learners in mathematics in South Africa at different school levels, especially grade 9 calls for different approach to learning. This research argues that enhanced application of volitional strategies is possible and, in fact desirable if learning situations have to promote mathematics achievement in areas with a presence of traditional teaching style. The purpose of this study is to construct volition enhancing self-regulation model to improve grade 9 mathematics learner performance in rural community schools.
The model suggests combining precepts from activity theory and constructivist views as basis. The cyclic learning states of pre-action, action or volition control, and pro-action phases emanating from self-regulation sequence of self-monitoring, self-evaluation and self-reflections form the key concept of the volition model. However the sustained view maintains the education system model as proposed by Howe (2004:153) that includes input, processes and output contributing towards mathematics achievement. Hence the volition model considers the characteristics of teacher, implemented curriculum, teaching and instruction among its components to advance an understanding of their influence in mathematics performance.
A mixed method research design, in which quantitative and qualitative are combined to achieve the outcomes of the research problem, is chosen for this research study project to provide a purposeful research framework. The finding revealed that the overall Volition Component Inventory (VCI) in pre - / post - and retention tests displayed good reliability, acceptable communality and acceptable construct validity for the VCI questionnaire. The post-test findings using the Univariate Tests of Significance, Effect Sizes, and Powers with partial eta2 values comparing experimental and control groups indicate the intervention effect of high statistical
significance suggesting that the educational intervention enhanced mathematics performance. Another findings on how the experimental and control groups compared on learner VCI fields for in pre - / post - and retention tests using Least Square means crossover design model indicate that the enhanced intervention for volition self-efficacy, emotion control, failure control and self-control pressure, energy usage, planning and initiating ability and attention control was of significant main effect. Also the findings between control and experimental group using a three way and nested ANOVA on both learner use of volition strategy use in pre - / post – and retention test indicate pre-test to post-test, a sharp increasing effect of intervention. Hence the results revealed that it is possible to support volition mode of self-regulation competencies and mathematical achievement by self-regulation intervention within regular mathematics lessons of grade 9 learners. Furthermore the findings from the quantitative and qualitative data-analysis and interpretations, and literature review, guided the researcher in proposing a construct for volition enhancement self-regulation model to improve mathematics learner performance in grade 9 rural community schools.
In this context, our study adds to research as it realizes that mathematics learning can be directly influenced by combining mathematics related strategies with cross-curricular self-regulation strategies in order to improve learner performance. / PhD (Mathematics Education), North-West University, Potchefstroom Campus, 2014

Versuchungsresistenz - Entwicklung eines fMRT-Paradigmas zur Erfassung von Selbstkontrolle und Impulsivität - neuronale Aktivierungsmuster, Persönlichkeit und genetische Faktoren -Wimmer, Lioba 29 February 2016 (has links) (PDF)
Täglich treffen Menschen zahlreiche Entscheidungen. Häufig stellt sich dabei die Frage, ob man einer direkt verfügbaren Versuchung nachgibt oder versucht, ein in der Zukunft liegendes Ziel zu erreichen. Impulsivität und Selbstkontrolle können dabei als konfligierende Persönlichkeitseigenschaften im Entscheidungsprozess gesehen werden.
In der Entscheidungsforschung wird postuliert, dass zwei getrennte Systeme existieren, die bei jeder Wahl berücksichtigt werden: ein eher impulsives und ein reflektives System. Je nach Stärke der Anteile der beiden Systeme werde eine Entscheidung getroffen. Neben behavioralen Theorien haben die Befunde der kognitiven Neurowissenschaften dazu beigetragen, den beschriebenen Systemen relevante Hirnregionen zuzuschreiben: limbische Regionen, vor allem das ventrale Striatum, werden dabei vor allem mit dem impulsiven System in Verbindung gebracht, während kortikale Strukturen, im Besonderen dorsolateraler präfrontaler (DLPFC) und anteriorer cingulärer Kortex (ACC), mit Selbstkontrolle assoziiert werden. Das Belohnungssystem ist eng mit dopaminergen Signalübertragungswegen verbunden, die unter anderem durch Gene für Dopamin- Rezeptor, -Transporter und -Abbau beeinflusst werden.
Studien zur Erforschung der behavioralen Grundlagen und neuronalen Zusammenhänge menschlicher Entscheidungen haben bislang vor allem Forced-Choice-Paradigmen verwendet, bei denen sich die Probanden zwischen einer sofort verfügbaren, kleineren Belohnung und einer späteren, größeren Belohnung entscheiden müssen. Bei dieser Operationalisierung erfolgt bei jeder Entscheidung eine eindeutige Zuordnung zum impulsiven oder selbstkontrollierten System, alltägliche Entscheidungen hingegen sind meist deutlich weniger eindeutig und transparent.
Aus diesem Grund wurde im Rahmen der vorliegenden Arbeit ein fMRT-Paradigma entwickelt, das menschliche Entscheidungen abbildet, ohne auf diese dichotome Einteilung zurückzugreifen. So sollten mithilfe des Versuchsresistenz-Paradigmas (VR-Paradigma) sowohl Belohnungsareale aktiviert, als auch schwierige Entscheidungen abgebildet werden. Dabei wurden den Probanden in neun Blöcken jeweils zwanzig kleine Geldbeträge (zwischen einem und 99 Cent) angeboten, von denen pro Block nur fünf gutgeschrieben werden konnten.
Es wurden zwei aufeinander aufbauende Studien an unterschiedlichen Stichproben durchgeführt: Im Rahmen der ersten Studie wurden 53 männliche Studenten untersucht. Neben dem VR-Paradigma wurden psychologische Fragebögen erhoben, bei 30 Probanden erfolgte außerdem eine genetische Analyse hinsichtlich dreier Dopamin-assoziierter Polymorphismen (COMT Val158Met, DAT1 und DRD2/ANKK1 Taq 1A).
In einer zweiten Studie wurden die Daten 16 männlicher alkoholabhängiger Patienten sieben bis 14 Tage nach Beginn eines Entzugs und 16 männlicher Kontrollprobanden analysiert. Diese wurden ebenfalls dem VR-Paradigma unterzogen und begleitend mithilfe psychologischer Fragebögen untersucht.
Bei der Auswertung wurden die Entscheidungen im Sinne eines 2x2-Designs nach Antwort (Ja oder Nein) und Höhe (Hoch (≥ individuellem Median der gutgeschriebenen Beträge) oder Niedrig (< individuellem Median) eingeteilt. Dabei sollten Belohnungsreaktionen vor allem bei höheren Beträgen auftreten, während schwierige Entscheidungen und Versuchungsresistenz über die Ablehnung hoher Beträge und die Annahme niedriger Beträge abgebildet werden.
Die Auswertung der ersten Studie erbrachte einen signifikanten Unterschied der Reaktionszeiten im VR-Paradigma bezogen auf die Höhe der angebotenen Beträge und die Interaktion von Antwort und Höhe, wobei die Ablehnung eines hohen Betrags die längsten Reaktionszeiten hervorrief. Bei hohen im Vergleich zu niedrigen Beträgen konnten Aktivierungen im bilateralen ventralen Striatum, rechten DLPFC, ACC, in der bilateralen Insula und im inferioren parietalen Lobus (IPL) nachgewiesen werden. Bei der Ausübung von Versuchungsresistenz (Interaktion der Haupteffekte) wurde dagegen der linke DLPFC aktiviert. Im Rahmen einer Konnektivitätsanalyse (psychophysiologische Interaktionen) konnte eine Korrelation der Aktivierung des linken DLPFC mit dem ventralen Striatum nur bei hohen abgelehnten Beträgen, nicht aber bei niedrigen zurückgewiesenen Beträgen gefunden werden. Bezüglich der Verbindung zwischen neuronaler Aktivierung und Persönlichkeit konnten Zusammenhänge der Belohnungsreaktion mit hohen Werten auf Impulsivitätsskalen und für Risikoverhalten sowie niedrigen Werten für Selbstkontrolle nachgewiesen werden. Für die Aktivierung in Kontrollarealen bei Versuchungsresistenz konnte ein entgegengesetzter Effekt beobachtet werden. Die Auswertung der genetischen Daten ergab eine signifikante stärkere Aktivierung des ventralen Striatums bei 10R- Homozygoten. Bei 10R-Homozygoten liegt eine erhöhte Zahl von Dopamin-Transportern an der Synapse vor, was am ehesten zu einer verringerten Verfügbarkeit von Dopamin im synaptischen Spalt führt.
Die Auswertung von Studie 2 erbrachte signifikante Unterschiede der Reaktionszeiten nur bezüglich der Höhe der angebotenen Belohnung, die Gruppenzugehörigkeit (Patient- Kontrolle) und die Interaktion der Haupteffekte hatten keinen Einfluss. Die Patienten behielten signifikant häufiger eine Kaufoption bis zum Ende eines Blocks übrig. Bei der neuronalen Aktivierung konnte eine stärkere Aktivierung des linken DLPFC und linken IPL bei Patienten nachgewiesen werden. Außerdem fanden sich signifikant höhere Werte auf impulsivitätsassoziierten Persönlichkeitsskalen für Patienten im Vergleich zu Kontrollen.
Im Rahmen der vorliegenden Arbeit konnten mit dem neu entwickelten VR-Paradigma neuronale Aktivierungen in Belohnungs- (v.a. ventrales Striatum) und Kontrollarealen (v.a. linker DLPFC und ACC) nachgewiesen werden. Außerdem scheint eine Konnektivität zwischen DLPFC und ventralem Striatum abhängig von der Notwendigkeit zur Ausübung kognitiver Kontrolle zu bestehen. Das Ausmaß neuronaler Aktivierung war mit Persönlichkeitsmaßen von Impulsivität und Selbstkontrolle korreliert, hier haben also interindividuelle Unterschiede in neuronaler Aktivierung Auswirkungen auf die Persönlichkeit. Der gefundene Einfluss des DAT1-Gens steht im Gegensatz zu bisherigen Befunden, dies kann mit der unterschiedlichen Operationalisierung zusammenhängen. Unterschiede zwischen alkoholabhängigen Patienten und Kontrollen hinsichtlich einer stärkeren Aktivierung in Kontrollarealen bei Patienten lassen vermuten, dass Patienten einen höheren kognitiven Aufwand zur Kontrollausübung aufwenden müssen.
Mithilfe des neuartigen Versuchungsresistenz-fMRT-Paradigmas zur Versuchungsresistenz werden bekannte Hirnregionen im Entscheidungsprozess angesprochen und es bietet darüber hinaus neue Einblicke in Interaktionseffekte. Weiterführende Studien können über eine Anwendung des Paradigmas an einer größeren klinischen Stichprobe in Verbindung mit genetischer Analytik neue Einblicke in Suchtmechanismen und deren Aufrechterhaltung ermöglichen.

Managing discipline in a post-corporal punishment era environment at secondary schools in the Sekhukhune school district, LimpopoNtuli, Lesheleba Tiny 28 June 2013 (has links)
Managing discipline in schools is one of the fundamentals of effective teaching and learning. It is evident that ineffective discipline management in schools would eventually jeopardize the efficacy of teaching and learning. So, it is crucial that legitimate, democratic disciplinary measures and procedures should be employed.
The aim of this study was to investigate ways of managing discipline in selected secondary schools within Sekhukhune District, Limpopo. A qualitative research approach was chosen, employing research methods which included individual interviews, focus group interviews and non-participant observation. The investigation focused on four secondary schools which were purposefully sampled to participate in the study. The research concentrated only on the views of the educators and the principals.
This investigation revealed that principals and educators still find themselves in a predicament in applying contemporary disciplinary measures due to a lack of training or minimal training regarding alternatives to corporal punishment. / Educational Leadership and Management / M. Ed. (Education Management)

Anger Displayed by Second Grade Students Who have Experienced Periodic, Planned Role-Playing/Discussion Activities and a Comparable Group of Second Grade Students Who have Not Experienced Periodic, Planned Role-Playing/Discussion ActivitiesRogers, Pamela S 01 January 1980 (has links)
Is there a difference between how a group of second grade students who have experienced periodic, planned role playing/ discussion activities and a comparable group of second grade students who have not experienced periodic, planned role playing/ discussion activities will display anger when presented with problem situations?

The Effects of Environmental Consequences and Data Collection in the Behavior-Contracting Treatment of ObesityRumph, Robin R. 05 1900 (has links)
This study investigated the effects of environmental consequences and data 'collection in a behavior contracting procedure for obesity. Also, a validity study examined the GSR as a subject-independent-monitoring technique. Sixteen subjects matched on sex and percent overweight were assigned to one of three contract conditions or to a no-treatment condition. The Data Only Contract Group received consequences for data collection. The With Consequences Contract Group received consequences for data collection and behaviors relevant to weight loss. The Without Consequences Contract Group received no consequences for data collection or behaviors relevant to weight loss. The With Consequences Contract Group lost significantly more weight ( p ≤ .05) than the No Treatment Group. Specific effects were not determined.
The results of the validity study suggest that the GSR may not be a valid instrument as a subject-independent-monitoring technique. Factors affecting the galvanic skin response's- effectiveness were discussed.

L’étiologie des différences individuelles dans le contrôle de soi à la petite enfance : une étude des facteurs génétiques et environnementauxBoivin, Guillaume 06 1900 (has links)
Contexte et objectifs. Le contrôle de soi serait, selon Gottfredson et Hirschi (1990), le meilleur prédicteur de la délinquance. Il serait déterminé, selon les auteurs, exclusivement par les facteurs environnementaux (compétences parentales, surveillance et punition) et ce, avant l'âge de sept ans. Il ne serait pas question des facteurs génétiques dans l'étiologie du contrôle de soi. Or, plusieurs études récentes menées à l'adolescence et à l'âge adulte avancent que le contrôle de soi serait d'origine partiellement génétique. Deux objectifs seront poursuivis. D'abord, considérant que le contrôle de soi, tel que décrit par Gottfredson et Hirschi (1990), n'ait jamais été étudié spécifiquement à la petite enfance, il a été nécessaire d'opérationnaliser le construit à la petite enfance à partir des informations existantes sur le contrôle de soi. Ensuite, il s'agira d'estimer l’influence relative des facteurs génétiques et environnementaux sur le contrôle de soi à 18, 30 et 48 mois.
Méthodologie. En tout, 672 familles de jumeaux monozygotes ou dizygotes de la grande région métropolitaine de Montréal ont pris part à l'Étude des jumeaux nouveau-nés du Québec. Les items utilisés proviennent du Child Behavior Checklist (Achenbach, 1994) et ont été obtenus via les parents des jumeaux. La zygotie a été évaluée à l’aide du Zygosity Questionnaire for Young Twins (Goldsmith, 1991) et le sexe a été déterminé par les assistants de recherché. Trois temps de mesures furent étudiés : 18 mois (n = 664), 30 mois (n = 617) et 48 mois (n = 531).
Résultats. Les résultats des analyses factorielles confirmatoires suggèrent par le biais des estimés qu'il soit possible de générer un facteur du contrôle de soi à la petite enfance à partir des indicateurs sélectionnés et que ceux-ci se regroupent sous l'égide d'un seul facteur. Les résultats concernant l’étiologie montrent que les différences individuelles observées seraient, majoritairement influencées par les facteurs génétiques (additifs ou de dominance) suivis par les environnements uniques.
Conclusion. Les résultats suggèrent que les facteurs génétiques jouent un rôle important dans l’étiologie des différences individuelles dans le contrôle de soi tôt dans le développement alors que les environnements communs ne seraient pas impliqués. Les résultats sont compatibles avec les études menées à l'adolescence et à l'âge adulte et sont en contradiction avec les postulats de Gottfredson et Hirschi (1990). / Context and goals. Self-control is described by Gottfredson and Hirschi (1990) as the most reliable predictor of delinquency. The authors suggest that self-control is determined primarily by environmental factors, including parental monitoring of their children, the recognition of bad behaviors, the appropriate correction of the bad behaviors, of which the individual differences are deemed stable by age seven. The main goal of this study was to examine the genetic and environmental etiology of self-control in toddlerhood. Specifically, this study aims to 1) evaluate whether self-control can be reliably operationalized in toddlerhood; and 2) estimate the genetic and environmental contributions of individual differences in self-control in this period of development.
Methods. The sample consisted of 672 pairs of monozygotic or dizygotic twins who grew up in the greater Montreal area. Information about the twins were collected from the parent that knows the child best using the Child Behavior Checklist (Achenbach, 1994) whereas the zygosity was determined by the Zygosity Questionnaire for Young Twins (Goldsmith, 1991). For the purpose of this study, only three waves of data collection were used: 18 months (n = 332 pairs), 30 months (n = 309 pairs) et 48 months (n = 266 pairs).
Results. The results support the idea self-control can be estimated from six behavioral and attitudinal indicators (impulsivity, disobedience, bad temper, aggressive behavior, hyperactivity and inattention) and derived in a single factor as early as 18 months of age. At 18, 30 and 48 months of age, the best fitted models indicated that only genetic and uniquely experienced environmental factors underlined individual differences in self-control.
Interpretation. Contrary to Gottfredson and Hirschi’s (1990) hypothesis, individual differences in self-control in toddlerhood is moderately explained by genetic factors, the reminder being relegated to uniquely experienced environments. Also noteworthy is the absence of a shared-environmental etiology, part of which is expected to comprise family influences experienced by both twins, such as the parental monitoring of their children, the recognition of bad behaviors and the appropriate correction of the bad behaviors.

Optimal policy and inconsistent preferences : behavioural policymaking and self-controlChesterley, Nicholas January 2015 (has links)
This thesis takes three different perspectives, using theoretical and experimental techniques, on time-inconsistent preferences and how the existence of multiple selves can affect both consumer behaviour and policy design. Across domains such as retirement saving, health, and educational achievement, intertemporal choice presents a challenge for both individuals and policymakers. The first paper, 'Choosing When to Nudge: Designing Behavioural Policy around Decision-Making Costs,' considers how behavioural policy, which has proven increasingly popular with policymakers, affects welfare. I find that for present-biased consumers, behavioural policies help some consumers but can inefficiently discourage others from optimizing. Such policies therefore have an ambiguous effect on welfare, and similar to traditional policies, can impose equity-efficiency tradeoffs. Monopolies may increase welfare given their incentive to simplify consumer decisions instead of exploit switching costs. The second paper, 'Virtue and Vice with Endogenous Preferences,' considers behaviour when preferences are affected by consumer decisions. I introduce agents whose temptation to consume in the present is affected by how much they choose to save for the future. I find that differences between agents can trap them in divergent paths of self-improvement -- saving more, they value the future more, making saving optimal -- or binging -- consuming more makes them indifferent to future costs, making consumption optimal. At the extreme, it is frequently an optimum for a consumer to consume their entire wealth. The final paper, 'Bet You Can't Eat Just One: Consumption Complementarity and 'Self'-Control' considers an intrapersonal game between a moderate cold self and a hot self that wants to indulge. In equilibrium, sophisticated selves best respond to each other's behaviour: the cold self over-abstains and the hot self over-indulges to avoid inducing the other state. I test these ideas in the lab, and find that subjects on a diet who were induced to consume a piece of chocolate before the experiment indulge more in chocolate during the experiment, even when the initial indulgence was imposed by the experimenter. Eating a piece of chocolate, this suggests, can induce a period during which chocolate is more appealing.
