Mathematics education research has focused on developing teachers' knowledge or other visible aspects of the teaching practice. This paper contributes to conversations around making a teacher's thinking visible and enhancing a teacher's pedagogical reasoning by exploring the use of pedagogical documentation. In this paper, we describe how a…

This study investigated the influence of stress-induced factor as determinants of undergraduates' numerical reasoning and decision making processes (NRDMP) in pseudo-mathematics courses. The study employed descriptive research of the survey type. A sample of 400 undergraduates was selected using purposive sampling technique. A questionnaire used…

This research is reviewing students' process of decision making intuitively, analytically, and interactively. The research done by using discount problem which specially created to explore student's intuition, analytically, and interactively. In solving discount problems, researcher exploring student's decision in determining their attitude which…

How might pre-service elementary teachers' misconceptions of proof and counterexamples influence their teaching of proof? To investigate this question, two types of interviews--task-based and scenario-based--were designed to elicit pre-service elementary teachers' (PSTs) conceptions of proof and counterexamples and how those conceptions might…

This paper refers to the concept of semiotic and theoretic control describing resources to conduct decisions in epistemic processes. We consider an argumentation process from a complex problem-solving activity involving different conceptual frames related to parabolas. Using a micro-analytical interpretative lens, we will show that, in order to…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
