The development of academic English proficiency and the time it takes to reclassify to fluent English proficient status are key issues in monitoring achievement of English learners. Yet, little is known about academic English language development at the domain-level (listening, speaking, reading, and writing), or how English language development is associated with time-to-reclassification as an English proficient student. Although the substantive findings surrounding English proficiency and reclassification are of great import, the main focus of this dissertation was methodological: the exploration and testing of joint modeling methods for studying both issues. The first joint model studied was a multilevel, multivariate random effects model that estimated the student-specific and school-specific association between different domains of English language proficiency. The second model was a multilevel shared random effects model that estimated English proficiency development and time-to-reclassification simultaneously and treated the student-specific random effects as latent covariates in the time-to-reclassification model. These joint modeling approaches were illustrated using annual English language proficiency test scores and time-to-reclassification data from a large Arizona school district. Results from the multivariate random effects model revealed correlations greater than .5 among the reading, writing and oral English proficiency random intercepts. The analysis of English proficiency development illustrated that some students had attained proficiency in particular domains at different times, and that some students had not attained proficiency in a particular domain even when their total English proficiency score met the state benchmark for proficiency. These more specific domain score analyses highlight important differences in language development that may have implications for instruction and policy. The shared random effects model resulted in predictions of time-to-reclassification that were 97% accurate compared to 80\% accuracy from a conventional discrete-time hazard model. The time-to-reclassification analysis suggested that use of information about English language development is critical for making accurate predictions of the time a student will reclassify in this Arizona school district.

Magister Educationis - MEd (Mathematics and Science Education) / A large percentage of South African learners held inadequate or alternative conceptions that might hinder them from developing a valid understanding of various scientific concepts and generalizations. This study explored the conceptions of Senior Phase learners on magnetism, chemical change of substances and the environment. More explicitly, the study attempted to investigate the influence of the learners" age, language and gender issues on their understanding of these scientific concepts. The study is underpinned by socio-cultural constructivism as espoused by Vygotsky (1978). The research sample comprised 250 Senior Phase learners (grades eight and nine) from secondary schools in the Metro Central District in the Western Cape. The study used the following six research instruments for data collection: Science Achievement Test (SAT), Context Test, Cloze Test, Picture Test, Science Vocabulary Test and an interview schedule. The tests were administered to all the participants while the interview was conducted with six participants.This study was a descriptive research of a survey type and data was collected and analyzed using both quantitative and qualitative methods.The data collected was analyzed quantitatively using the Statistical Package for Sciences (SPSS) in order to obtain descriptive statistics that were used to explore the conceptions of senior phase learners in magnetism, chemical change substances and the environment in the Metro Central district while data from the tape recorder and notes taken during the interview, were analyzed qualitatively.

Doctor of Education / Department of Educational Leadership / Royce Ann Collins / There is a need for critical thinking skills in our society. This research study examines graduate student’s growth in critical thinking after experiencing a specifically designed curriculum. This study evaluated the effectiveness of the U.S. Army Command and General Staff Officer Common Core Course to change student critical thinking skills and habits of the mind attributes, and further examined instructor perceptions of the curriculum, instructional methods, and instructor skills and behaviors that impact student critical thinking development within the Core Course. This study used an explanatory sequential mixed method research design in order to answer the four research questions and test their respective hypotheses. Eight student staff groups (n=120) were selected from the Command and General Staff Officer Common Core Course Class 15 population, and the quantitative data used to conduct the analyses was derived from a pretest and posttest using the Military and Defense Critical Thinking Inventory (MDCTI), a nationally recognized instrument designed specifically for individuals in the defense and military profession. The qualitative component of the study consisted of focus group interviews conducted with instructors from the eight selected staff groups (n=24) to examine their perceptions on the role of the curriculum, instructional methods, and instructor skills and behaviors in developing student critical thinking. The data collected from these interviews were analyzed and presented using a collective case study approach. Analysis of the student pretest and posttest score change results indicated statistically significant changes in analysis, induction, deduction, and overall critical thinking skills, and in the communicative confidence, professional confidence, expression, and directness habits of the mind attributes. Further analysis indicated that there was no statistically significant change differences in critical thinking skills or habits of the mind attributes between the teaching team groups. Analysis of the qualitative data revealed nine themes that were categorized within the theoretical framework of curriculum, instructional methods, and instructor skills and behaviors. Four additional themes emerged which did not address the role of curriculum, instructional methods, and instructor skills and behaviors in developing student critical thinking. These themes included: lack of contact time, the importance of the physical classroom configuration, the military/school culture, and student attributes.

abstract: There are many educational issues connected to the exponential growth of the Latina/o population in the U.S. One such issue is Latina/os’ educational outcomes in the area of literacy. Despite the increased attention to subpopulations of students (e.g., English language learners, students with disabilities) there is little attention given to students that do not fit neatly into one subcategory, which positions Latina/o language minorities (LMs) with learning disabilities (LDs) in a liminal space where their educational services are fragmented into either being a student with LD or a LM student. Unfortunately, labels that are meant to afford students resources often result in fragmenting students’ educational experiences. This becomes evident when attempting to locate research on students who have ethnic, linguistic, and ability differences. Rarely are their educational needs as Latina/o LMs with LD met fluidly. Understanding the intersections of ethnicity, language, and ability differences in situated literacy practice is imperative to creating the deep, nuanced understanding of how Latina/o LMs with LD might become proficient in the use of critical twenty-first century tools such as new literacies. In this study I used cultural historical activity theory in combination with New Literacy Studies (Cope & Kalantzis, 2009; Gee, 1996) and intersectionality (McCall, 2014) to examine how Latina/o LMs with LD’s participated in literacies across in- and out-of-school contexts with the following research questions: In what ways does participation in literacy change for Latina/o LMs with LD as they move between in- and out-of-school? What situated identities do LMs with LD enact and resist while participating in literacy across in- and out-of-school contexts? / Dissertation/Thesis / Doctoral Dissertation Special Education 2015

Online learning is increasingly prevalent in education and one area which stands to benefit from this approach is work based learning. This area is characterised by time-poor students and a requirement for flexibility in time and location. Online learning could be considered a solution to these issues, providing greater flexibility than campus based offerings, but it is not a panacea. Online learning suffers from a range of issues, particularly in retention, generally seeing attrition rates between 10% and 20% higher than traditional education. This research investigates an emerging method for delivering online education to work based learners and how it compares to traditional methods with respect to engagement. The method is named bite sized learning, and the core principle is that lessons are delivered in very short, bite sized chunks. These chunks are delivered on a daily basis, comprised of content, guidance and practical tasks. Each chunk also includes a requirement for social interaction with a learning peer group. This work takes an action research approach, combined with grounded theory and mixed methods. The author proposes the use of a methodology "stack", utilising each of these approaches, which will be shown to enable rigorous evaluation and development of an emerging educational method. The mixed methods employed comprise learning analytics and qualitative course evaluation survey data. To begin the work, a series of identical bite sized courses are quantitatively analysed in order to propose a reliable measure of engagement for bite sized learning. This concludes that a measure of daily participants produces the most effective results. Using the methodology "stack," the body of this research takes a 3 stage practice-based approach. A set of live bite sized learning courses are studied, via the "stack", producing an evaluation, an experiment and a resulting theory for bite sized learning. The evaluation reveals current patterns of engagement within bite sized learning, and enables the development of an early theory. The results of this inform the development of an experiment, intended to test the effect of the daily format versus a simpler form of bite sized learning, delivering all content at the beginning. These experimental results, allied with further qualitative data, allow further development and refinement of a bite sized learning theory. It is discovered that bite sized learning does offer a number of unique advantages to work based learners when compared to traditional methods. It does also, however, come with difficulties. The advantages include increased participation, as well as an increase in discipline and priority around online learning. The difficulties centre around participation in social tasks and on daily participation. Both reduce flexibility, but hold the advantages of increased priority and increased learning for some. The research concludes with the presentation of a three path theoretical model of bite sized learning, each level suited to a particular context and course aim. The paths develop in sequence, and educators may choose the path which best suits their own teaching environment. The resulting paths force a choice between emphasising flexibility, involvement or learning, and advice is offered on how to choose the ideal model based on the learners involved.

This study explores the use of computer simulations to supplement learning in Science lessons, specifically the photoelectric effect. This study uses the Felder and Silverman Learning Style Model (FSLSM) as a theoretical framework to investigate the use of simulations as it provides a useful lens through which to explore the consistent way in which a person learns regardless of the teaching method or content learnt. Using this theoretical framework, this research investigates the experiences of learners with different learning styles when an interactive computer simulation is used to aid teaching the photoelectric effect in Physical Science. This case study used qualitative data collected from 17 computer literate Grade 12 learners in three different classes at a secondary school in Nelspruit, Mpumalanga. Analysis of the data collected in this study shows that when the simulation is used in Science, the learning experience of the learners is enhanced. Positive experiences for all four the Dimensions in the FSLSM could be indentified when the ICS was used and this could be linked to specific learning styles. Sensory and Intuitive learners enjoyed conducting the experiment that would normally require unsafe conditions and that the experiment could be set up quickly and with ease. The different dimension brought about by using the ICS was enjoyed by Intuitive learners. The visualisation of the abstract physical systems enhanced the learning for Visual and Verbal learners, whilst Global and Sequential learners felt that they gained a deeper understanding of the photoelectric phenomenon by using the ICS. Reflective learners enjoyed the precision of their pseudo-experimental data, but the Active learners felt that they did not understand the graphs given in the ICS. The interactive control variables and the fact that the learners had an option to work in either a group or on their own, benefitted both Active and Reflective learners. / Dissertation (MEd)--University of Pretoria, 2014. / gm2014 / Science, Mathematics and Technology Education / unrestricted

The growing field of mobile learning (m-learning) research concerning the use and effectiveness of mobile assisted language learning (MALL) in second and foreign language (L2) education reflects the possibilities of smart mobile technological devices to facilitate students’ control over their own learning. This research aims to find the pedagogical affordances of mobile learning in combination with Web 2.0 tools with a particular focus on the use of smartphone and Facebook as tools to enhance teaching and learning of English for English as a Second Language learners. Using Design Based Research (DBR) as an approach to conduct this study, the initial design framework was developed from the literature and the exploratory phase. It was tested and developed through a series of iterations and the impacts of each iteration were evaluated using interviews and qualitative data analysis. 37 participants were involved in this study; 12 in the Exploratory Study, 17 in Iteration 1 and 8 in Iteration 2. One of the most important findings reported in the first iteration is the impact of a sense of social obligation whereby participants felt under pressure from their peers to post and to participate. This social obligation effect can have both positive and negative consequences for learning and was further explored in the second iteration. Based on the findings from both iterations, this study suggested a design framework to be used by future research that explored ways in which pedagogical designs for m-learning with social networking can take this social obligation effect into account in order to avoid its negative consequences and make best use of its positive consequences.

Magister Scientiae (Physiotherapy) - MSc(Physio) / In South Africa, the Education White Paper 6 on Special Needs Education (2001) Building an inclusive education and training system stated that the special schools would be resource centres for ordinary schools that admit learners with disabilities. Occupational therapists,physiotherapists, speech and language therapists (collectively called therapists) had previously been employed in special schools, but under the new structure, would form part of the district-based support teams to provide their support to ordinary and full service schools.Therapists working in an inclusive education system would need to change the focus of their model of support from a medical model of direct support to a health-promoting model of indirect support. The aim of the current study was to determine whether therapists are changing their model of support in building inclusive and health-promoting schools and also to determine the barriers and facilitators they experience in providing their support in an inclusive education system. This study used both qualitative and quantitative methodology.The quantitative component was a non-experimental, descriptive, cross-sectional design,using one questionnaire in a survey. The questionnaire was used to determine the type of support provided to schools. In total, 97 therapists, who worked at special schools in the Western Cape, participated in the study by completing the questionnaire. The test-retest results of the questionnaire indicated that most of questions (63%) showed perfect agreement (Kappa 0.81-1.0). Quantitative data analysis was done by descriptive statistics, using SPSS.The results indicated that therapists were using the medical model of support combined with a more holistic approach using the principles of the health-promoting framework. The qualitative component involved three group interviews, which were held at three different special schools, in three different education districts, with a total of 12 therapists. The group interviews were used to determine the barriers and facilitators that either prevent or promote provision of support. Qualitative data analysis was done by using content analysis with codes and themes to determine barriers and facilitators. The barriers included the following: therapists’ uncertainty about roles; lack of networking, lack of certain competencies and training; delayed response from district; lack of policy;autocratic leadership styles; exclusion from the district-based support team; concern to support learners at special school; therapists being based at the special school; lack of human resources; insufficient time; cost of therapists’ training; education department circuit boundaries affecting communication;negative attitudes of principals and educators; and parents’ non-involvement. The facilitators included therapists’ competencies to fulfil roles; educators’ positive attitude; meetings; training to improve therapists’ skills; the co-ordinating role of the district-based support team;and the supportive role of learner support educator and the principal. This study provides evidence concerning therapists’ roles and the barriers and facilitators which therapists experience regarding their support provision in an inclusive education system.

Magister Educationis - MEd / The primary purpose of this study was to understand how certain factors could contribute to the low achievement levels of Grade 12 learners from two selected rural schools. For the purpose of this research these two schools were referred to as schools A and B. The academic performance of Grade 12 learners from schools A and B has been very low since 2008-2010. On average, these two senior secondary schools produced less than 5% of their learners who qualified for entrance to the University of Namibia (Ministry of Education, 2003-2010).

Magister Educationis - MEd / Mathematical Literacy has a dual meaning in South Africa. On the one hand it alludes to an understanding of the role of Mathematics in the real world. On the other hand it refers to a subject that is taken by students who generally do not do well in Mathematics and who do not wish to do a pure Mathematics course, This research focuses on the identification and investigation of errors, misconceptions and alternative ways of working in the responses of students in the final grade 12 Mathematical Literacy examination. The aim was to identify the errors, misconceptions and alternative ways of working and to discuss possible reasons for these errors and misconceptions. This aim was governed by the principle that feedback to students and teachers form a vital component in the teaching and learning process. This analysis only focused questions pertaining measurement in Mathematical Literacy. An analytical framework was constructed based on common errors and misconceptions identified by various researchers’ in the field of Mathematics. This analytical framework was used to classify and analyse the errors, misconceptions and alternative ways of working in Mathematical Literacy. The analysis was done using document analysis on a randomly selected sample of Mathematical Literacy scripts taken from across all education districts in the Western Cape. Great care was taken to prevent bias and cross checking was done by peers to ensure that the categories of errors were agreed on. The results of the analysis revealed that the errors identified for Mathematics are common to those of Mathematical Literacy. The findings in this project suggest that the analysis and feedback of errors and misconceptions may help to improve teaching and learning in Mathematical Literacy.
