To what extent does the use of computational tools offer teachers the possibility of constructing dynamic models to identify and explore diverse mathematical relations? What ways of reasoning or thinking about the problems emerge during the model construction process that involves the use of the tools? These research questions guided the…

This study investigated intellectual development in 4-7 years old Greek and Chinese children. They were examined on speeded performance, working memory, reasoning, and self-awareness tasks in order to investigate possible effects of learning the Chinese logographic system on possible differences in intellectual development between these ethnic…

This paper presents the results obtained from a study comparing the strategies used by 1,070 Chinese students and 1,002 Singaporean students from primary grade 6 to secondary year 2 in solving three fraction-related problems. It is part of the author's Ph.D. study, which involves more word problems on speed. The Chinese students performed better…

Two complementary processes involved in mathematical modelling are mathematising a realistic situation and applying a mathematical technique to a given realistic situation. We present and analyse work from two undergraduate students and two secondary school teachers who engaged in both processes during a mathematical modelling task that required…

Last summer, the Democracy Imperative and the Deliberative Democracy Consortium, two national networks linking academics and deliberative democracy practitioners, hosted a national conference, No Better Time: Promising Opportunities in Deliberative Democracy for Educators and Practitioners ("No Better Time," 2010). Over 250 civic leaders,…

Reflective learning has been described as a promising approach for ameliorating the impact of continuing education (CE) programs. However, there are still very few studies that have investigated how occupational therapists use reflection to improve the integration of CE program content in their decision-making processes. The study objectives were…

Medical technology continues to improve, increasing life expectancies and capabilities of children with chronic illnesses and disabilities. Pediatric health issues have an impact on children's academic, emotional, behavioral, and social functioning. This article reviews a consultative Biopsychoeducational Model, based on a problem-solving process,…

Microarray is a high throughput technology to measure the gene expression. Analysis of microarray data brings many interesting and challenging problems. This thesis consists three studies related to microarray data. First, we propose a Bayesian model for microarray data and use Bayes Factors to identify differentially expressed genes. Second, we…

A number of cars drive along a narrow road that does not allow overtaking. Each driver has a certain maximum speed at which he or she will drive if alone on the road. As a result of slower cars ahead, many cars are forced to drive at speeds lower than their maximum ones. The average velocity in the queue offers a non-trivial example of a mean…

Pedagogical content knowledge (PCK) has been embraced by many of the recent educational reform documents as a way of describing the knowledge possessed by expert teachers. These reform documents have also served as guides for educators to develop models of teacher development. However, in the United States, few if any of the current models…

The author offers innovative approaches to 3 topics that are typically only briefly mentioned (if at all) in money and banking courses. The first topic is a Treasury bill auction experiment in which students have an opportunity to participate directly. The results from a class of 14 money and banking students are used to explain how an instructor…

This article presents a tutor-centered tutoring model that aims to develop and establish the pedagogical-disciplinary knowledge and skills of prospective teachers. The tutoring model and the research that accompanied its implementation are presented. The tutor-tutee pairs worked for two five-session cycles for two semesters, enabling prospective…

This paper provides a road map for universities to follow in responding to corporations that are in need of a solution to the dilemma of building an executive development program and simultaneously providing their executives with a high quality MBA degree. Difficulties experienced by many corporations are complicated by the fact that MBA programs…

This study addressed the problem of why students with learning disabilities in mathematics too often fail to develop multiplicative and divisional concepts/operations. We conducted a constructivist teaching experiment with 12 students (nine 5th and three 4th graders). This report focuses on three students' conceptual progress, particularly on…

Purpose: This paper examines the critical effect of learning from past changes on employees' evaluations regarding the extent that a crisis can be controlled and prevented. It is suggested that previous changes incorporate elements of a double-loop learning process that shape managerial perceptions of crisis controllability and crisis prevention.…
