This study focused on the mathematical content knowledge of prospective teachers in Iceland. The sample was 38 students in the School of Education at the University of Iceland, both graduate and undergraduate students. All of the participants in the study completed a questionnaire survey and 10 were interviewed. The choice of ways to measure the mathematical content knowledge of prospective teachers was grounded in the work of Ball and the research team at the University of Michigan (Delaney, Ball, Hill, Schilling, and Zopf, 2008; Hill, Ball, and Schilling, 2008; Hill, Schilling, and Ball, 2004), and their definition of common content knowledge (knowledge held by people outside the teaching profession) and specialized content knowledge (knowledge used in teaching) (Ball, Thames, and Phelps, 2008). This study employed a mixed methods approach, including both a questionnaire survey and interviews to assess prospective teachers' mathematical knowledge on the mathematical topics numbers and operations and patterns, functions, and algebra. Findings, both from the questionnaire survey and the interviews, indicated that prospective teachers' knowledge was procedural and related to the "standard algorithms" they had learned in elementary school. Also, findings indicated that prospective teachers had difficulties evaluating alternative solution methods, and a common denominator for a difficult topic within both knowledge domains, common content knowledge and specialized content knowledge, was fractions. During the interviews, the most common answer for why a certain way was chosen to solve a problem or a certain step was taken in the solution process, was "because that is the way I learned to do it." Prospective teachers' age did neither significantly influence their test scores, nor their approach to solving problems during the interviews. Supplementary analysis revealed that number of mathematics courses completed prior to entering the teacher education program significantly predicted prospective teachers' outcome on the questionnaire survey.Comparison of the findings from this study to findings from similar studies carried out in the US indicated that there was a wide gap in prospective teachers' ability in mathematics in both countries, and that they struggled with similar topics within mathematics. In general, the results from this study were in line with prior findings, showing, that prospective elementary teachers relied on memory for particular rules in mathematics, their knowledge was procedural and they did not have an underlying understanding of mathematical concepts or procedures (Ball, 1990; Tirosh and Graeber, 1989; Tirosh and Graeber, 1990; Simon, 1993; Mewborn, 2003; Hill, Sleep, Lewis, and Ball, 2007). The findings of this study highlight the need for a more in-depth mathematics education for prospective teachers in the School of Education at the University of Iceland. It is not enough to offer a variety of courses to those specializing in the field of mathematics education. It is also important to offer in-depth mathematics education for those prospective teachers focusing on general education. If those prospective teachers teach mathematics, they will do so in elementary school where students are forming their identity as mathematics students.

This dissertation explored how a professional developer, using the Center’s Professional Development Model for Innovating Instruction, supported two teachers’ acquisition of the knowledge needed for their mathematics instruction. Through analysis of detailed field notes and semi-structured interviews of two experienced elementary school teachers working in an urban, high-need school, this dissertation studied how the design and situate components of the Center’s Professional Development Model for Innovating Instruction can lead to multiple ways of supporting teachers’ instruction depending on the teachers’ needs and interests. Findings from these two case studies suggest that there is a need for teacher education mathematics programs—In-service and pre-service—to provide teachers with the knowledge for innovative mathematics instruction needed to create demanding learning experiences in their classrooms. This dissertation elaborates on these results, discusses connections with other research, and ends with implications of these results, in terms of their immediate application and the need for future research.

Organizations leading education reform of the 1980's have challenged teacher education programs at colleges and universities across the nation to improve the subject matter content preparation of teachers. Past methods of program development and techniques to assess teacher's knowledge competence have been one-sided in their approach. New research studies on expert vs novice teachers show that expert teachers are more efficient in carrying out standard patterns of instruction. This nation's mathematics community has engaged in a revitalization of mathematics curricula. Traditional mathematics is being transformed to become a powerful science. Using the growing body of research, the National Council of Teachers of Mathematics have developed standards for improving the teaching and learning of mathematics. Oregon's Department of Education has also established standards to meet the needs of a changing mathematics curricula and the challenges of a changing society. This study identified the specific content knowledge taught in the mathematics curricula within colleges and universities which offer four, five or fifth year teacher education programs. It then compared these findings against teacher identified origins of elementary, middle and high school teachers' mathematics content knowledge relative to the Essential Learning Skills of Oregon. It was found that teachers' content knowledge of the Essential Learning Skills of Oregon was not directly related to their preparation as teachers; at the elementary and high school levels, there was no direct relationship found between teachers' degrees and their teaching assignment; there was no apparent relationship between teachers' knowledge of the Essential Learning Skills of Oregon and graduation from an Oregon college or university; there was no apparent relationship between teachers' lack of knowledge of the Essential Learning Skills of Oregon and graduation from a non-Oregon college or university. / Graduation date: 1990

In recent years much has been said and written concerning the widening gap between the newer developments in mathematics and that which is traditionally taught in secondary schools. Not unnaturally, leading scholars in mathematics have looked at the school programmes and found them wanting in many respects. [...]

This study used diagnostic tests, questionnaires and interviews to investigate explore teachers’ subject content knowledge (SCK) and pedagogical subject knowledge (PCK). It also explored teachers’ and learners’ misconceptions within the topic of graphicacy and how teachers’ SCK and PCK possibly affect learner achievement. A small sample of teachers were drawn from the Keiskammahoek region; a deep rural area of the Eastern Cape. These teachers were part of the Nelson Mandela Metropolitan University (NMMU) Amathole Cluster Schools Project who were registered for a three-year BEd (FET) in-service programme in mathematics education. As part of the programme they studied mathematics 1 and 2 at university level and received quarterly non-formal workshops on teaching mathematics at FET level. The findings of this study suggest that teachers with insufficient SCK will probably have limited PCK, although the two are not entirely dependent on each other. In cases where teachers’ displayed low levels of SCK and PCK, their learners were more likely to perform poorly and their results often indicated similar misconceptions as displayed by their teachers. This implies that we have to look at what teachers know and what they need to know in terms of SCK and PCK if we are to plan effectively for effective teacher development aimed at improving learner performance.

"Out of genuine desire to prepare oneself to handle, in a more effective way, the teaching of eighth grade mathematics, there comes to mind such questions as these: 1. What are the needs or tasks or problems of eighth grade pupils to which arithmetic can make a contribution? 2. What content is available in the state adopted textbooks? 3. How well is this material adapted to school needs of pupils of this age? 4. What reliable tests can be found? 5. What materials and plans of a general nature can be found or developed which, if revised later to fit the specific classroom situation, may prove of help in improving the teaching of mathematics?"--Introduction. / "August, 1952." / Typescript. / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements for the degree of Master of Science." / Advisor: W.

Statistically skilled workers are highly demanded in today's world, which means we need high-quality statistics education. There has been a continuously increased enrollment of statistics students. At the college level, introductory statistics courses are typically taught by professors who often hold a strong qualification in mathematics but may lack formal training in statistics education and statistical analysis. Existing literature claims that a unique way of thinking--statistical thinking or reasoning--is essential when teaching statistics, especially at the introductory level. To elaborate and expand on the issue of statistical thinking, a qualitative study was conducted on 15 mathematics teachers from a local community college to discuss differences between statistics and mathematics as academic disciplines and exemplify two types of thinking--statistical thinking and mathematical thinking--among mathematics teachers who teach college-level introductory statistics. Additionally, the study also inspected mathematics teachers' pedagogical ideas influenced by each type of thinking, some of which were recognized as "pedagogically powerful ideas" that transcend students' conceptual understanding about statistics. The study consisted of two online questionnaires and one interview. In the two online questionnaires, participants explored and rated five technology options for teaching statistics and self-evaluated their technology, pedagogy, and content knowledge. During the interview, participants solved nine statistical problems designed to elicit statistical thinking and addressed pertinent pedagogical questions related to each problem's statistical concept. A framework that hypothesizes aspects of mathematics teachers' statistical thinking and mathematical thinking in statistics was created, summarizing the prominent differences in problem-solving, variability, context, data production, transnumeration, and probabilistic thinking. Select responses from participating mathematics teachers were provided as examples of each type of thinking. Furthermore, it was revealed that mathematics teachers with a different type of thinking tended to cover different statistical topics, deliver the same statistical concept in different ways, and assess students' knowledge with different emphases and standards. This study's results have implications: if statistics is to be taught by mathematics teachers, statistical thinking is required to implement pedagogically powerful ideas for furthering meaningful statistical learning and to unveil the differences between statistics and mathematics.

This study characterizes the mathematical knowledge upon which secondary school algebra teachers draw when pondering problem situations that could arise in the teaching and learning of solving algebraic equations, as well as examines the potential connections between teachers' knowledge and their academic backgrounds and teaching experiences. Seventy-two middle school and high school algebra teachers in Texas participated in the study by completing an academic background questionnaire and a written-response assessment instrument. Eight participants were then invited for followup semi-structured interviews. The results revealed three topic areas in equation solving in which teachers' mathematical subject matter understanding should be strengthened: (a) the balancing method, (b) the concept of equivalent equations, and (c) the properties of linear equations in their general forms. The participants provided a wide range of instances of student misconceptions and difficulties in learning how to solve linear and quadratic equations, as well as a variety of strategies for helping students to improve their understanding. Teachers' subject matter knowledge played a central or prerequisite role in their reasoning and decision-making in specific contexts. When the problem contexts became broader or more general, teachers drew from across the three basic domains of mathematical knowledge for teaching (knowledge of the mathematical subject matter, knowledge of learners' conceptions, and knowledge of didactic representations) and showed individual preferences. Overall, teachers tended to rely more heavily upon their knowledge of students' specific or general learning characteristics. Statistical analyses suggest that teachers who majored in mathematics and who had the most experience in teaching first-year or more advanced algebra courses performed significantly higher on the assessment than their counterparts, and there is a linear relationship between teachers' performance and the number of advanced mathematics course they have taken. Neither course-taking in mathematics education nor number of years of algebra teaching made a significant difference in their performance. Results are either unclear or inconsistent about the role of teachers' (a) use of algebra textbooks, (b) prior experience with a method or a manipulative, and (c) participation in professional development activities. Teachers also rated (a) collaborating with and learning from colleagues and (b) dealing with student conceptions and questions as highly influential on their professional knowledge growth.

This study investigated the experiences of four participating student teachers in using multiple representative approaches in the teaching of Grade 6 proportion word problems. The multiple representative approaches include the Between Comparison Method, the Within Comparison Method, the Diagrammatic Method, the Table Method, the Graph Method, the Cross-product Method, and the Oral Informal Method. An intervention programme was organised, using workshops where student teachers were prepared to teach Grade 6 proportion word problems using multiple representative approaches. The teaching practice lessons of the four participating student teachers in two primary schools were video recorded, and the focus group interview was conducted at the University Campus. With the exception of the Graph Method and the Cross-product Method, it was revealed that the multiple representative approaches were generally effective in the teaching of Grade 6 proportion word problems. The study further revealed that multiplicative relationships can be explored through using the different individual representative approaches. The study argues that the cross-product method is not the only way to teach Grade 6 proportion word problems. There are multiple representative approaches that should be used in conjunction with each other to enhance the teaching of proportion word problems. Furthermore, this study revealed that a number of challenges were encountered when using multiple representative approaches. The challenges include difficulties with the English language, different and unique abilities of the learners, lack of plotting skills and the lack of proficiency in the learners’ multiplication and division skills. This study made recommendations on the integration of multiple representative approaches in the mathematics education curriculum and textbooks. It further recommended that in-service workshops for teachers and student teachers on the integration of multiple representative approaches in the teaching of Grade 6 proportion word problems should be initiated.
