eric.ed.gov har udgivet: Karabatsos and Walker (2011) introduced a new Bayesian nonparametric (BNP) regression model. Through analyses of real and simulated data, they showed that the BNP regression model outperforms other parametric and nonparametric regression models of common use, in terms of predictive accuracy of the outcome (dependent) variable. The other, outperformed, regression models include random-effects/hierarchical linear and generalized linear models, when the random effects were assumed to be normally-distributed (Laird & Ware, 1982; Breslow & Clayton 1993), and when the random effects were more generally modeled by a nonparametric, Dirichlet process (DP) mixture prior (Kleinman & Ibrahim, 1998a,1998b). The authors argue that the new Bayesian nonparametric (BNP) regression model provides a novel, richer, and more valid approach to causal inference, which allows the researcher to investigate how treatments causally… Continue Reading →

eric.ed.gov har udgivet: This article describes a case study using an electronic learning platform for creating an interactive learning community through asynchronous discussion to enhance the initial field experience of secondary math and English teacher candidates enrolled in Field Experience. We identified three problems with the field experience course–lack of structure, isolation of the candidates in the field, and passivity of the candidates. To address these problems, we established three goals–to create a way for candidates to structure their reflections in the field, to create a learning community of pre-professionals, and to foster independence and assertiveness in our candidates. With these goals in mind, focused assignments were developed and implemented in an interactive online discussion forum. The results of this study have two important implications for teacher preparation. First, the… Continue Reading →

eric.ed.gov har udgivet: The universities and faculties which educate teachers of mathematics for teaching pupils/students of any age group from pre-school age to higher education carefully monitor and compare valuable results of this research, detect the areas in which the mathematical achievements of pupils should be improved at the national level and propose the ways to improve the quality of education and achieve better learning outcomes. We deem particularly valuable contributions of the researchers regarding the samples of poorer mathematical achievements at the “local level” in neighbouring countries, as well as the presentation of examples of good practice by means of which we pave the path towards better achievements of pupils and, consequently, the improvement in the quality of teaching mathematics at the “local,” as well as the global level.… Continue Reading →

eric.ed.gov har udgivet: This article reports on a study that investigated the causes underlying a sample of eighteen third-year Australian pre-service primary teachers’ negative beliefs and anxiety about mathematics. It was found that most of the participants’ maths-anxiety could be attributed to their primary school experiences in learning mathematics. Situations such as teaching mathematics or being evaluated in mathematics were noted as particularly stressful and mathematical topics such as algebra, space and number sense were specifically identified to cause maths- anxiety. The paper concludes with a brief discussion about the implications of these findings for an ensuing program whose purpose is to help these pre-service teachers address their negative beliefs and anxieties about mathematics.

eric.ed.gov har udgivet: The likelihood-to-act (LtA) survey measures impulsive and analytic dispositions in solving mathematics problems. The current version has 16 impulsive and 16 analytic items. Its validity was assessed using a sample of 27 in-service and 92 pre-service teachers. Both the impulsive and analytic subscales were found to have internal consistency reliability, but they were not correlated with one another. The impulsive subscale was predictive of correctness in classifying the LtA items. The analytic subscale was predictive of how well a participant would perform in Part 2 of a math test after taking Part 1 and being warned that some items could be tricky.

eric.ed.gov har udgivet: Undergraduate preservice teachers face many challenges implementing inquiry pedagogy in mathematics lessons. This study provides a step-by-step case analysis of an undergraduate preservice teacher’s actions and responses while teaching an inquiry lesson during a summer math camp for grade 3-6 students conducted at a university. Stumbling blocks that hindered achievement of the overall goals of the inquiry lesson emerged when the preservice teacher asked open-ended questions and learners gave diverse, unexpected responses. Because no prior thought was given to possible student answers, the preservice teacher was not equipped to give pedagogically meaningful responses to her students. Often, the preservice teacher simply ignored the unanticipated responses, impeding the students’ meaning-making attempts. Based on emergent stumbling blocks observed, this study recommends that teacher educators focus novice teacher preparation in… Continue Reading →

eric.ed.gov har udgivet: This submission contains the Proceedings of the 2011 Annual Meeting of the Canadian Mathematics Education Study Group (CMESG), held at Memorial University of Newfoundland in St. John’s, Newfoundland. The CMESG is a group of mathematicians and mathematics educators who meet annually to discuss mathematics education issues at all levels of learning. The aims of the Study Group are: to advance education by organizing and coordinating national conferences and seminars to study and improve the theories of the study of mathematics or any other aspects of mathematics education in Canada at all levels; and to undertake research in mathematics education and to disseminate the results of this research. These proceedings include plenary lectures, working group reports, topic session descriptions, new PhD reports, and summaries of ad hoc and… Continue Reading →

eric.ed.gov har udgivet: This research examines the critical factors in a science/math methods course and its effect on the dispositions of preservice elementary education majors. In order to break the cyclical axiom that “teachers teach as they were taught,” this study used a paired-t test design to indicate any significance. The preservice education majors indicated that they felt more prepared to teach developmentally-appropriate lessons in Life Science, Earth Science, Physical Science, and Astronomy. There was a development of a positive self-efficacy, which will have a great impact on the effectiveness of the new teachers. Constructivism as a theory of learning and teaching and as a significant factor in developing a heightened sense of self-efficacy was the theory used in the classes. In order to learn math and science, the learner… Continue Reading →

eric.ed.gov har udgivet: Student achievement and attitudes toward mathematics are influenced by the teacher, emphasizing the importance of quality teacher preparation. This study explored different preparations and the impact on pre-service teachers’ pedagogical content knowledge. The sample included 96 pre-service teachers enrolled in a math course at one Midwestern university. Results suggest that field experience combined with other aspects of mathematical teacher preparation impact pre-service teachers’ pedagogical content knowledge for mathematics. (Contains 7 tables.)

eric.ed.gov har udgivet: In a recent study at the University of Regina, preservice teachers were asked questions about their internship experiences of teaching mathematics. One question in the study focused on asking preservice teachers to recall their most meaningful experiences in the mathematics classroom during their internship, to which many responded with stories of how their students all of a sudden just “got” a concept and how this could even be visually detected. It is interesting to note the comparisons between their responses to this question about meaningful experiences and their responses to other questions concerning their images of math as a subject, their attitudes toward math, and their perceptions of what it means to know (in) math. Factors other than ability influence students’ approaches to challenges, their persistence (or… Continue Reading →
