New Zealand has been leading the world in terms of the data handling, and in more recent years, data visualisation approach in its school statistics curriculum. In 2013, bootstrapping and randomisation were added to the senior secondary school (Ministry of Education 2012). This paper gives an historical perspective of the people and groups that…

Mathematics educators have argued for some time that elementary school students are capable of engaging in algebraic thinking and should be provided with rich opportunities to do so. Recent initiatives like the Common Core State Standards for Mathematics (CCSSM) (CCSSI 2010) have taken up this call by reiterating the place of early algebra in…

In order to teach mathematics effectively, mathematics teachers need to have a sound mathematical knowledge, but what constitutes sound mathematical knowledge for teaching is subject to debate. This paper is an attempt to unpack what constitutes teacher knowledge of the concept of a function which is a unifying idea in the mathematics curriculum.…

The paper uses digital fabrication as a learning environment to demonstrate the importance of conceptual understanding of one-variable inequalities. These inequalities are hidden within two-variable inequalities used to construct geometric shapes the borders of which are the graphs of basic functions from the secondary mathematics curriculum. As…

Due to increased use of technology, the workplace practices of engineers have changed. So-called techno-mathematical literacies (TmL) are necessary for engineers of the 21st century. Because it is still unknown which TmL engineers actually use in their professional practices, the purpose of this study was to identify these TmL. Fourteen…

In this paper, an example is offered of a problem-solving task for senior secondary school students which was given in the context of a story. As the story unfolds, the task requires progressively more complex forms of linear programming to be applied. Coding in MATLAB is used throughout the task in such a way that it supports the increasing…

Many school-improvement efforts include time for teacher collaboration, with the assumption that teachers' collective work supports instructional improvement. However, not all collaboration equally supports learning that would support improvement. As a part of a 5-year study in two urban school districts, we collected video records of more than…

More than 15 years after the introduction of a standards-based curriculum reform, the mathematics teachers are positive towards the reform message but have not changed their classroom practice accordingly. To improve the impact of future reforms, it is important to learn from this situation and to better understand the role of the national policy…

To learn mathematical practices, students need opportunities to engage in them. But simply providing such opportunities may not be sufficient to support all students. Simultaneously, explicitly teaching mathematical practices could be problematic if instruction becomes prescriptive. This study investigated how teachers might make mathematical…

In the official curriculum documents of many countries, statistical thinking have become part of the mainstream in school curriculum. We argue that teacher capacity is a key dimension in realizing essential goals for developing students' statistical literacy, reasoning and thinking in practical teaching. In this paper, a construct of Teacher…

The study aims to identify the effect of using computerized based education on Eighth grade achievement in Math. In addition the study aims to identify the effect of gender on students' achievement who received computerized education. The study was based on the selection of students from two schools in Ma'an City one for females and the other for…

The ubiquity of the subject of percentages in our everyday life demands that math teachers and pre-service math teachers demonstrate a profound knowledge and thorough understanding of the concept of percentages. This work, which originated from one specific lesson in an 8th grade math class, studies the conceptual understanding and problem-solving…

Quebec students have generally excelled in international mathematics comparisons and 22% performed in the top category, Level 6, on PISA in 2012. Several countries with more extensive gifted programs scored and ranked considerably lower and had smaller proportions achieving Level 6. Does this mean a general mathematics curriculum with such indices…

This article addresses the policy implications of participation in international large-scale assessments (ILSAs), particularly the Programme for International Student Assessment (PISA), and the ways in which such implications might influence mathematics education. Taking Norway as a special case, this discussion focuses on insights into teaching,…

This study investigated the effect of van Hiele Phase-based Instruction (VHPI) on Ghanaian Pre-service Teachers' (PTs') geometric thinking in terms of the van Hiele Levels. A pre-test post-test quasi-experimental design was employed. There were 75 PTs each in the experimental group and the control group. Van Hiele Geometry Test (VHGT) was…
