This investigation concerned two major interests of many classroom teachers today: the pupils' social maturity and their personality. The problem was to determine the apparent relationship between these two factors in pupils of the first, second, and third grades of eight elementary schools in Wichita Falls, Texas.

Elementary school officials have reported difficulty motivating young African American boys to read. It is important that teachers understand why these children have not been motivated to read and create classroom environments that encourage reading motivation. The purpose of this basic qualitative study was to explore teachers' perspectives on best instructional practices for motivating 3rd -grade African American boys to read. The conceptual framework for this study consisted of critical race theory, self-determination theory, and the theory of social constructivism. The research questions focused on teachers' perspectives regarding 3rd -grade African American boys' motivation to read and best instructional practices in reading instruction for these students. Through a purposeful sampling strategy, 10 teachers were invited to participate and share their teaching experiences. The criterion for inclusion was that the participant taught reading to 3rd -grade African American boys. Data were collected from 5 teachers who agreed to participate through semistructured interviews. Recordings of the interviews were transcribed and analyzed using axial coding. Axial coding of the transcribed interview data and thematic analysis revealed 3 overarching themes: (a) best instructional practices, (b) motivation for reading, and (c) classroom resources. Results indicated that different types of instructional practices had influenced the teachers' perspectives on motivating these students to read. This study contributes to positive social change by providing school administrators and educational leaders with knowledge that may be beneficial to the initiation of policies, strategies, and procedures to motivate third-grade African American boys to read.

The purpose of this study was to collect and tabulate material which would be embodied in a revised course of study for the playground activities for grades one, two, and three of the elementary schools of Dallas, Texas.

The purpose of this research was to study the implementation of a professional learning community comprised of one group of third-grade teachers in a Florida elementary school where the emphasis was on research-based practices in the teaching of mathematics. Investigated were the growth of teachers‟ content knowledge in mathematics, specifically in the areas of multiplication and division, and the effects of their professional learning within their classrooms. Specifically this study looked at whether or not the participation of a group of third grade teachers in a professional learning community PLC improved the mathematical content knowledge of the participants of the study. This research design called for the research to be conducted in three phases. In Phase I, the researcher interviewed all participants using a researcher-designed interview guide. A researcher-adapted survey, based upon previously released items Ball (2008) was administered as a pre-test of mathematical content knowledge,. In Phase II of the study, the researcher documented the activities that occurred within a 10-week long professional learning community (PLC) of third-grade teachers. In Phase III of the research, a post-study interview was conducted with each of the participants by an independent observer to elicit participants‟ perceptions and observations based on their participation in the PLC. A post-test of content knowledge was also administered to the participants. Several themes were identified in the research study. These themes led to recommendations for practice and future research. Themes were related to the lack of iv mathematical understanding experienced by some teachers and the lack of professional development specifically related to mathematics, the value of the professional learning community, and the benefits of sharing current research and best practices. During this study, the participants were able to read and share examples of research-based best practices in mathematics, and participants then used this new information and additional mathematics content knowledge in their classrooms in teaching their students.

The purpose of this study was to investigate the extent to which the performance of Title I third grade students in a central Florida School District differed on tests administered under timed and untimed conditions. Further examined was the literature on reasons for the achievement gap which centered around seven different themes: (a) standardized testing, (b) achievement gap data and identified factors (c) deficit theory, (d) cultural mismatch theory, (e) extended time accommodations, (f) test anxiety and stress, and (g) timed versus untimed tests. Six Title I schools participated in this study by assigning 194 students to take the 2006 Released FCAT Reading Test under either timed or untimed conditions. Although there were no interactions between the covariates and testing conditions, those who were in the free or reduced lunch program or were in exceptional education programs had lower FCAT scores than those who were not. However, when school was included as a moderator, there was a statistically significant interaction between testing conditions and schools on FCAT scores indicating that the relationship between testing conditions and FCAT scores varied for each individual school. A factorial ANCOVA was conducted, and it was found that the mean differences between students who took the timed and untimed 2006 FCAT Reading Test varied from school to school after accounting for the covariates. For two schools, those students who took the untimed tests scored higher than those who took the timed tests. In contrast, those students who took the untimed tests scored lower than those students who took the iv timed test for one of the schools. There was no statistically significant difference for three of the schools. A factorial MANCOVA was used to compare reading performance on the 2006 Reading FCAT between the timed and untimed groups on domain specific tests. The relationship between testing condition and FCAT scores for each domain specific test varied depending on the individual school. Therefore, it could not be concluded from these analyses that testing conditions would consistently result in increases or decreases of student performance on standardized domain specific tests.

Thesis Ph.D. ((Applied Mathematics)) -- University of Limpopo, 2022 / The world is under threat from the devastating effects of the continued depletion of the Ozone layer. Increased global warming is causing catastrophic ecological damage and imbalance due to accelerated melting of glaciers, rampant runaway veld res, widespread floods and other extreme events. The delegates to the Cop26 Climate Change Summit were reminded that the continued burning of fossil fuels is releasing carbon into the atmosphere at an unprecedented pace and scale and that the world is already in trouble. Complete substitution of fossil fuels with clean energy sources is the only solution through which the world can be saved from the deleterious effects of global warming. However, total dependence on renewable energy sources can only be possible through novel technology that enables efficient energy utilization and conservation. For instance, the evolution of advanced techniques in manufacturing processes has led to the reduction in the size of various industrial and engineering designs that consume reduced amounts of energy. Efficient energy utilization in thermo-fluid flow systems can be achieved through entropy generation minimization. Entropy is a thermodynamic quantity that represents the unavailability of a system's thermal energy for conversion into mechanical work. In this study, thermodynamic analysis of reactive variable properties third-grade fluid flow in channels with varied geometries and subjected to different physical effects was investigated with the second law of thermodynamics as the area of focus. Entropy generation and inherent irreversibility analysis were the main focus of the study where the sensitivities of these quantities to the embedded parameters were numerically and graphically described and analysed. The semi-analytic Adomian decomposition method, the semi-implicit fi nite difference scheme and the spectral quasilinearisation method were employed to solve the nonlinear differential equations modelling the flow systems. The results reveal that the effects of the parameters on flow velocity, fluid temperature, entropy generation and inherent irreversibility cannot be neglected. In particular, conditions for entropy generation minimization were successfully established and documented. / University of Limpopo

Submitted in fulfilment of the requirement for the Degree of Master of Technology: Language Practice, Durban University of Technology, 2011. / The literacy levels in South African schools are alarmingly low. Educators are challenged in diverse classrooms with multicultural and multilingual learners as they are faced with the problems that these learners are experiencing in literacy. Educators therefore need to be able to adapt their teaching strategies to suit the needs of their learners to address learners’ different learning needs and styles. This study investigated the use of adapted teaching strategies used by grade 3 educators in literacy in selected schools in northern KwaZulu-Natal. A mixed methods research design was used which included the use of a questionnaire and semi-structured interviews to gather data. The findings which were linked to the literature review revealed that educators lacked adequate knowledge and skills to adapt their teaching strategies as they have not been adequately trained to teach literacy within multilingual contexts. Although some educators were using adapted teaching strategies they were not using them effectively in their multilingual classrooms while some educators did not have a wellstructured intervention programme at school to deal with learners who were experiencing problems with literacy. Inexperienced educators also had problems identifying learning styles and adapting their teaching strategies. This study found that teachers require continual professional development to enable them to effectively adapt their teaching strategies to suit individual learning needs and styles.

The following thesis focuses on the topic of the system of writing "Comenia Script", used by the pupils of the third grade of basic schools. The thesis consists - as usual - of two parts: a theoretical one and a practical one. The theoretical part deals with the school tuition of writing, the differences in the teaching of analytic- synthetic and genetic method, and forming of the individual handwriting. A substantial part focuses on the central theme, the Comenia Script (the circumstances of its origin, its shape characteristics, the course of its experimental testing, and current researches). The next chapter concerns itself with the scales designated for assessment of the writing (Matějček, Zelinková, Veverková). In the practical part we introduce the assessing scale of Jana Veverková (2011), adapted by us. By the means of this scale we were assessing the written expressions of ninety pupils using Comenia Script. At the same time, the pupils were taught by the analytic-synthetic or genetic method of reading and writing tuition, therefore we were able to compare the results also from the point of view of both methods. The aim of this thesis is to describe the typical written expression of a pupil using the Comenia Script and also adapting the Veverková assessment scale (2011), so that it convenes for...
