This study was undertaken in an attempt to determine the degree to which second year Mathematics education students consider critical thinking dispositions and attitudes to be important and to develop a curriculum-based mediational approach based on the data, to encourage the critical thinking dispositions and attitudes that appeared to be in need of encouragement. A literature study was undertaken to determine the positive critical thinking dispositions and attitudes students should possess. In addition it was also determined which teaching learning approaches will benefit the development of critical thinking dispositions and attitudes the most. The advantages as well as the processes and components that should form part of the mediational approach for the development of critical thinking dispositions were examined. A two-phase, sequential, explanatory mixed method study was subsequently undertaken with second-year Mathematics students at a South African university. The quantitative study made use of a self-developed questionnaire to determine the degree to which students consider critical thinking dispositions and attitudes important. Data emanating from the questionnaires were analysed and questions that had to be answered in narrative format were set for each student according to their own responses on the questionnaire. Narratives formed part of the qualitative component of the study in which students had to indicate factors that influence their critical thinking dispositions and attitudes, what could be done to improve the apparent unimportant critical thinking dispositions and attitudes and whether they regard the critical thinking dispositions and attitudes as important. Narratives were analysed and the results were used to explain the quantitative data. Results revealed that second year Mathematics education students do not consider critical thinking dispositions and attitudes, in particular inquisitiveness but also judiciousness, open-mindedness, systematicity, truth-seeking, analyticity and confidence in critical thinking to be very important and therefore these critical thinking dispositions and attitudes appeared to require encouragement. A curriculum-based mediational approach based on a section in the existing Mathematics module for second year education students was developed in order to encourage critical thinking dispositions in Mathematics. The study concluded with recommendations to encourage critical thinking dispositions and attitudes as well as proposals for future studies. / PhD, Education, North-West University, Vaal Triangle Campus, 2012

Private sector, government and the academia have been recognizing the value of a \'designerly\' approach to business problems, in the context that the traditional technical-rationality has been insufficient to address issues in the contemporary volatile, uncertain, complex and ambiguous environment. Design Thinking has been growing since Tim Brown, CEO of a prestigious global design agency, started advocating and disseminating this approach in the business environment ten years ago. As more organizations are implementing Design Thinking (DT), this research aims to analyze the relation between individuals\' Readiness for adopting DT in organizations and their thinking styles, namely Rationality and Experientiality. From the literature review, some authors characterize Design Thinking by its focus on human needs, open objectives so creativity can arise, iteratively, reliance on qualitative methods, intuition and experience, - to name some of the characteristics. Accordingly, the initial hypothesis of this research stated that individuals with high Experientiality score would be the ones with higher Readiness to adopt Design Thinking. A quantitative survey was designed based on existing instruments in the academic literature. For assessing the thinking styles, the Rationality-Experientiality Inventory (REI) developed by Pacini & Epstein (1999) was integrally applied; for measuring the individual\'s Readiness for adoption of Design Thinking, the Readiness for Organizational Change Measure (ROCM) developed by Holt, Armenakis, Feild, & Harris (2007b) was partially applied; and to collect the respondents\' understanding on Design Thinking, questions were designed based on the paper published by Glen, Suciu & Baughn (2014). The sample size had 251 valid respondents from the state of Sao Paulo (Brazil), with declared knowledge or experience with Design Thinking. One-way ANOVA was conducted to determine significant differences within the terciles of Rationality, Experientiality and Readiness-for-change and between the thinking styles terciles and the score of Readiness for adopting Design Thinking; Regression Analysis was conducted to determine, among all variables in the research, which are the ones explaining Readiness for adopting Design Thinking. The results pointed out that the group of individuals with high score of Rationality (third tercile) presented higher Readiness for adopting Design Thinking, as well as the third and first terciles of Experientiality. Furthermore, when Rationality and Experientiality scores were analyzed together, both thinking styles did have influence on the individuals\' Readiness for adopting Design Thinking. The understanding of the level of individual\'s thinking styles provides some light on the challenges ahead regarding the acceptance of Design Thinking. Smoother and more efficient change management programs can be designed for educational programs relying on Design Thinking or for departments in organizations implementing Design Thinking. These findings may implicate in further researches in the cognitive field of Design Thinking, as the success of DT adoption in organizations can be influenced by the thinking style profile which is dominant in the selected department or functional area to be implemented. / Private sector, government and the academia have been recognizing the value of a \'designerly\' approach to business problems, in the context that the traditional technical-rationality has been insufficient to address issues in the contemporary volatile, uncertain, complex and ambiguous environment.

In an age of substantial educational reform, the teaching and learning of 'thinking-skills' are considered to be an integral component of a child's education. Further, they are considered an important factor in developing skills which may contribute to increased learning outcomes for all learners. Current reform agenda nominate a range of 'thinking-skills' and processes that inform essential lifelong learnings and that are supported by characteristics that all learners should exhibit. At the heart of such prescription is a vision of a future in which 'process' rather than 'knowledge' will be the focus. A fundamental paradigm shift is pressing, and so too, the revised role of the teacher. Teacher practices that assist students to search for their own understandings rather than follow other people's logic are paramount and essential to the successful implementation of educational change. This case study presents one teacher's approach to the provision of 'thinking-skills' instruction in a primary school classroom for year-six children. The three objectives of the project were first, to trial a different pedagogical approach, second, to influence and change the 'thinking' habits of youngsters, and third, to encourage students to employ 'good thinking' in order to maximize learning outcomes. The model for implementation was underpinned by philosophical approaches gleaned from the literature, which were caring, humane, stimulating and creative. An eclectic mix of insights and strategies were employed to target full immersion of students and teacher into a 'Thinking-Skills Classroom'. Data were gathered from two groups of student participants who represented two discrete learning contexts. One context was that of the Trial Classroom, where the 'immersion' process sought to create a 'culture of thinking', in which 'thinking' was the focus of all teaching, learning, and operating activity. The context of the Control Classroom, was one in which 'thinking' was not the focus of all instruction and learning, but rather, was taught in an incidental and less formal manner. The aim of this study was to determine whether significant educational outcomes would become apparent in the Trial Classroom, that is in a context where children were immersed in, and learned to use, a range of strategies aimed at progressing them as independent, confident and 'accomplished thinkers'. The teaching experiment that was 'The Thinking-Skills Classroom', proved successful. The research has revealed effective 'transfer' after instruction for students in the Trial Classroom. Learners effectively applied new 'thinking understandings' into everyday thinking situations, in addressing real-life problem solving, and in producing evidence of new ways of operating. Across all strata of academic ability students from the Trial Classroom increased their thinking prowess. A category was established for 'excellent thinkers', where students demonstrated acquisition of a different set of skills from those normally associated with 'good thinking'. Students developed increased self-confidence, risk-taking initiatives and independence across the board as a result of increased thinking ability. A study of this kind may be helpful to other teacher/researchers who are considering instructional and curriculum change in light of wider paradigmatic change in education. Although this particular study would be difficult to replicate, this researcher's story can be usefully interpreted to allow insights and generalizations from the case-study to be made. These may serve as a catalyst for other innovative school-based pedagogies to emerge, and for new learning approaches to be considered and trialled, in order to prepare students for life and learning in the Twenty-First Century.

The nurturing of critical thinking skills is one of the cornerstones of Outcomes Based Education (OBE). This study investigated to what extent teachers provide opportunities for the development of critical thinking skills in Grade 8 in Mathematics classrooms. A literature study was undertaken to highlight the importance and nature of the development of critical thinking skills in the Mathematics classroom, and to establish how critical thinking could be nurtured during the teaching, learning and assessment of Mathematics. Various teaching methods and assessment strategies, types of learning material, a variety of classroom activities and how to create a classroom conducive to the development of critical thinking skills were explored. The literature review provided the framework to design a questionnaire that was utilized to obtain the perceptions of Grade 8 Mathematics teachers and learners regarding the opportunities provided for the development of critical thinking skills in Mathematics classrooms. By means of quantitative, non-experimental descriptive research, the self constructed, closed-ended questionnaire was administered to a convenient sample of a purposively selected group of Mathematics teachers (n = 92) and learners (n = 204) in the Ekurhuleni District of Gauteng, South Africa. The triangulation of learner and teacher data revealed that teachers do have an understanding of the importance of critical thinking in the Mathematics classroom, but that their understanding is not always fully translated into practical opportunities for the development of critical thinking skills. It was revealed that teachers do make use of questioning and allow learners to communicate during problem-solving, which are important strategies for the development of critical thinking. However, it was evident that teachers appear to be inhibiting the development of critical thinking skills by relying heavily on the use of textbooks and transmission of knowledge during teaching, and seem not to acknowledge the merits of cooperative learning and real life experiences during the teaching and learning of Mathematics. The study is concluded with recommendations on how to nurture and improve critical thinking in the Mathematics classroom. / Thesis (M.Ed.

Critical thinking ability is imperative for nurse practitioners in the multidimensional unfolding health care arena. Consensus as to what critical thinking entails has yet to be articulated. This non-empirical study thus set out to clarify the concept "critical thinking. Walker and Avant's (1995) proposal for conducting a concept analysis was used within the qualitative research paradigm. Literature selected from the fields of education, philosophy, nursing and psychology was consulted as the main source of data. Thematic and theoretical sampling of literature were also embarked upon during the later stage of the research to add density to emergent categories and themes. Categories were organised according to the Strauss and Corbin (1995) paradigmatic model; indicating the antecedents, disposition of the thinker, attributes and critical attributes, and outcomes of critical thinking. The findings indicate that critical thinking is a complex, multidimensional, dynamic, existential and context dependent mental operation. The essence of critical thinking is further illuminated by the construction of a model case and additional cases. The concept critical thinking is finally succinctly defined. The implications that critical thinking holds for nursing education and practice are spelled out. / Health Studies / M.A. (Health Studies)

Contributions from elementary education to the practice and reality of critical thinking are rare, largely because attempts in basic education to elucidate a concept of critical thinking have a hard time breaking through the elusiveness and indeterminacy that characterize the history and reality of the concept. This situation is due to, and a consequence of, the difficulty of delimiting critical thinking from related fields, such as metacognition, higher-order-thinking, problem solving, informal logic, reasoning skills, and decision making, to name a few. Texas school authorities designed and put into practice a battery of tools to evaluate critical thinking through the assessment programs TAKS and STAAR, without taking a position regarding the indeterminacy problems of the content of critical thinking. The purpose of this study was to reconstruct the pieces of the critical thinking model imparted to Texas elementary school children since 1999 and continues today. The findings indicate that the critical thinking model implemented in Texas elementary schools is a particular version of a skills-only approach of critical thinking that follows the classical logical paradigm, consisting of two sets of complementary skills. This model acquaints students with the components and structure of five types of arguments while it fails to substantiate the logic of argument support that demonstrates how reasons support claims and the strength of support. The application of an adequacy conditions rubric showed the strengths of the model at the argumentation analysis level, yet it showed clear signs of incompleteness and inconsistencies at the argument structure level that distort its purpose and function.
