I describe an assignment by school administrators to develop a journal ranking system for the department of mathematics to be incorporated into our departmental assessment plan for all tenured and tenure track faculty.

This paper reports on a case study which explores the co-creation of a zone of proximal development (ZPD) in a mathematics teaching-learning activity in a Norwegian kindergarten. To capture the complexity of teaching and learning mathematics in kindergarten the study uses qualitative methods within an interpretative paradigm. The findings…

Like terms are usually defined for variables with numerical coefficients. While the definition is sufficient to combine polynomial terms, it does not help the students to combine radical, logarithmic, or trigonometric terms. The purpose of this paper is to propose a lesson that introduces a broader definition of like terms and trialed with a group…

In response to the well-documented challenges associated with the 'mathematics problem' in UK higher education, many institutions have implemented a programme of mathematics support. Previous surveys within the UK, undertaken in 2001, 2004 and, most recently, 2012, have shown growth in the number of institutions offering such support and indicate…

The article aims to present an excerpt from the research that investigates knowledge to teach arithmetic in practical classes in teacher training courses. More precisely, we are looking for traces of prescriptions of practices at a knowledge systematization level that we seek to objectify in a set of articles from the journal "A Eschola…

This study explored 1634 Chinese eighth-grade students' domain- and task-specific self-efficacy and its relationship to their problem-posing performance. In particular, the linear regression model, generalized additive model (GAM), and piecewise regression model (PRM) were used to detail the linear and non-linear relationships between these…

The current study examined digits correct per minute (DCPM) growth using explicit timing procedures across varying instructional set sizes (ISSs) and dose. Specifically, the study used a randomized group design to compare DCPM growth within three different ISSs (9, 18, and 36 multiplication facts) across three different levels of dose (2-, 4-, and…

This article examines the mathematical activity of five-year-old Liam to explore the difference between the mathematics games designed for children and the children's games that emerge through playful activity. We propose that this distinction is a salient one for teachers observing mathematical play for evidence of mathematical sense making.

An intelligent tutoring system for learning basic statistics, called Stat-Knowlab, is presented and analyzed. The algorithms implemented in the system are based on the competence-based knowledge space theory, a mathematical theory developed for the formative assessment of knowledge and learning. The system's architecture consists of the two…

Fractions are an important mathematical concept for both more advanced mathematical concepts and daily living activities (e.g., cooking) and thus are important for all students to learn. In this study, researchers explored the use of the virtual-abstract (VA) instructional sequence to teach three middle school students with disabilities three…

This paper focuses on the emergence of abstraction through the use of a new kind of motion detector--WiiGraph--with 11-year-old children. In the selected episodes, the children used this motion detector to create three simultaneous graphs of position vs. time: two graphs for the motion of each hand and a third one corresponding to their…

This article describes an inquiry-oriented real analysis classroom in which students were guided to discover mathematics for themselves. To support student inquiry, the framework of "five practices" from K-12 education was used. To illustrate this framework, two case examples are given from actual discussions that took place in this…

In this paper, we report how 5-year-olds' arithmetic skills developed through participation in an 8-month-long intervention. The intervention program aimed to enhance the children's ways of experiencing numbers' part-part-whole relations as a basis for arithmetic skills and was built on principles from the variation theory of learning. The report…

In recent years, several researchers have tried to use stories and games as a starting point for learning mathematics. This is allegedly able to increase students' mathematical abilities and make learning mathematics more enjoyable. Therefore, this research is aimed to design a mathematics learning trajectory in pattern number using…

Early math success in the PreK classroom is recognized as a strong predictor of later academic success. However, many early childhood teachers report they lack the content knowledge, confidence and beliefs to deliver high quality math experiences in their classrooms. Professional development opportunities to gain and expand these skills are often…
