Through the lenses of statistical investigations and cognitive demands, we examined bivariate data tasks offered in US high school mathematics textbook series--a popular representative of three curriculum types: traditional, integrated, and hybrid. We developed a framework grounded in literature of association topics for the inclusion and…

This paper reports a two-year research project studying Indonesian primary and secondary teachers' mathematics-related beliefs (MrB) and mathematical problem-solving knowledge for teaching (MPSKT). In the first year, a quantitative study involving 80 primary teachers, 70 lower secondary school, and 55 upper secondary schools from four districts in…

While there is abundant research reporting the impact of Lesson Study as a professional development framework for qualified teachers, its potential within initial teacher education remains relatively unexplored. We present a particular model of formal Lesson Study which has been experienced annually for a decade by Irish pre-service primary…

Background: Nowadays, the attention to integrate Science, Technology, Engineering and Mathematics (STEM) education to the existing curriculum is widely increasing around the world. In the early childhood education settings, many researchers have discussed the importance of early introduction to STEM education for children. However, the initiatives…

Virginia Highlands Community College (VHCC) implemented MTH 155 -- Statistical Reasoning Co-Requisite -- in the spring semester of 2018. MTH 155 replaced MTH 146 on VHCC's campus. Prerequisites for this course are the first five developmental MTE modules. The intended co-requisite audience for this new course consists of students having…

Research on teacher noticing in the field of mathematics education research has increased in the last decade; however, only a few studies have investigated the social and cultural impact on teachers' noticing. This paper describes results of an international comparative study on (in-service) mathematics teachers' professional noticing in China and…

Do your students say that one object is "bigger" than another without attending more precisely to the attribute they are comparing? Do they have difficulty naming numbers from 11 to 19? Do some students still count all while their classmates are counting on or counting by tens? What tasks can you offer--what questions can you ask--to…

Learning trajectories/progressions are an emerging research focus in mathematics education. A set of descriptors of early progress in mathematics was developed for students with complex needs. Developers leveraged off existing research-based frameworks and meta-analyses, as well as integrating findings from individual research studies in some…

625 primary and secondary students from schools in Melbourne and Geelong completed the WIFI Questionnaire to nominate what they valued in their mathematics learning. A content analysis of students' responses to an open-ended question about what they valued most resulted in a list of 64 unique values. A new, fourth category of values in mathematics…

The crucial reason for the common dislike, fear, and even hatred of mathematics by students and others is probably not the nature of mathematics itself, but the way the subject is portrayed and taught. We propose that instead of a mathematics curriculum that focuses on concepts and techniques (which is often seen), it might be more productive if…

This paper focuses on the curriculum links between statistics and science that teachers need to understand and apply in order to be effective teachers of the two fields of study. Meaningful statistics does not exist without context and science is the context for this paper. Although curriculum documents differ from country to country, this paper…

This report is based on an activity completed by 89 Grade 6 students carrying out a statistical investigation with a focus on posing an initial question given a context and then refining it for a chosen data set. Having reached a conclusion based on evidence from their data analysis, students were given additional information on the context and…

This article details an initial analysis of the transition of a second level curriculum reform to higher education in Ireland. The reform entitled 'Project Maths' involved changes to what second level students learn in mathematics, how they learn it, and how they are assessed. Changes were rolled out nationally on a phased basis in September 2010.…

Mathematics education, both nationally and internationally, is facing a number of challenges with significant on-going shifts in the structure, content, and core principles of mathematics curricula in countries around the world. For example, in Ireland there was an ambitious reform of the post-primary mathematics curricula in 2010 with further…

As part of a larger study, we report findings on teachers' use of the Common Core State Standards for Mathematics (CCSSM) and teacher resources (TR) that were included with teachers' published curriculum programs. We analyzed 147 lesson planning interviews with 20 middle school teachers to understand how teachers interpreted and enacted the CCSSM…
