This article describes sixth-grade students' engagement in two model-eliciting activities offering students the opportunity to construct mathematical models. The findings show that students utilized their knowledge of fractions including conceptual and procedural knowledge in constructing mathematical models for the given situations. Some students…

This paper is about the development of a task sequence to help overcome the fragmented understanding of the "function" concept that students often bring with them into the initial stage of upper secondary school level. Our aim is to make the students' use of functions more flexible in certain respects, for example when functions are…

Mathematical relationships are crucial elements to consider for learning mathematics. However, too often students pay more attention to the calculations to be done rather than the reasons for doing them. Relying on the relational paradigm to support elementary school students, we proposed two specially designed tasks to help students recognize and…

Teaching introductory statistics using curricula focused on modeling and simulation is becoming increasingly common in introductory statistics courses and touted as a more beneficial approach for fostering students' statistical thinking. Yet, surprisingly little research has been conducted to study the impact of modeling and simulation curricula…

A recent research report from the International Literacy Association (ILA, 2015) discussed the current challenges facing today's educators, noting the increasing diversity of students' backgrounds and needs, coupled with the higher expectations and standards being widely adopted to prepare students for 21st-century skills. The ILA (2015) document…

Analytical thinking is the competency needed by students in order to compete and achieve success in the professional field for the 21st Century. Research that aims to examine the most optimal learning model in empowering students' analytical thinking needs to be done since many students have low ordered thinking skills. Through this…

This study focused on the effect of examinees' ability levels on the relationship between Reflective-Impulsive (RI) cognitive style and item response time in computerized adaptive testing (CAT). The total of 56 students majoring in Educational Technology from Shandong Normal University participated in this study, and their RI cognitive styles were…

The aim of this study was to modeling the relationship between of school administrators' creative and critical thinking dispositions in relation to their decision-making styles and problem solving skills. A total of 586 school administrators participated in research from a district selected through the random sampling method. Data was collected…

Children in a first-grade class who were taking their first steps in formal mathematical knowledge were given a sequence of five modelling tasks during their regular mathematics lessons. These tasks were different in nature from the problems they encountered in their textbooks. They are more complex and challenging, requiring analysis of the…

Mathematical literacy (ML) is a compulsory subject in South Africa for those learners who choose not to do mathematics to Grade 12 level. ML is designed to enable a learner to become a self-managing person by providing opportunities to analyse and solve real-life problems through the mathematisation of contextual situations. The subject thus lends…

In support of efforts to foreground functions as central objects of study in algebra, this study provides evidence of how secondary students use trigonometric functions in contextual tasks. I examined secondary students' work on a problem involving modeling the periodic motion of a Ferris wheel through the use of a visual programming environment.…

This paper attempts to quantify the accuracy limit of "nextitem-correct" prediction by using numerical optimization to estimate the student's probability of getting each question correct given a complete sequence of item responses. This optimization is performed without an explicit parameterized model of student behavior, but with the…

Service modelling has become an increasingly important area in today's telecommunications and information systems practice. We have adapted a Network Design course in order to teach service modelling to a mixed class of both the telecommunication engineering and information systems backgrounds. An integrated approach engaging mathematics teaching…

Women and girls, particularly women and girls of color, remain underrepresented in STEM disciplines. This underrepresentation begins as early as late elementary school age. Educators, particularly those in informal STEM education, can help address gender inequity in STEM by understanding how research can be translated into actionable strategies.…

This study aims to explore the relations between the factors of the start-up environment and entrepreneurial intentions of students in universities in Vietnam and the Philippines by combining key elements of the theory of reasoned action, theory of planned behavior, theory of entrepreneurial events and model of entrepreneurial potential. Research…
