The COVID-19 global pandemic has required everyone to make sense of data about community spread, levels of risk, and vaccine efficacy. Yet research shows that students are underprepared in data literacy. Tanya LaMar and Jo Boaler argue that data science education provides an opportunity to address this problem while providing much needed updates…

Teachers are responsible for teaching, and when they plan, they are part of a complex non-linear social practice of curriculum making. When planning, teachers draw on curriculum materials, which are often designed to promote reform; however, previous studies show that this is not always the case. A study on planning for mathematics teaching in…

This paper makes a significant contribution to contemporary debates over the direction curriculum reforms should take. It challenges claims that progressive pedagogies can exclude disadvantaged learners from gaining access to powerful knowledge and argues that greater attention needs to be given to learner agency and subject didactics. It reports…

Evaluation of the K-13 curriculum (2013 Curriculum) on the value of the national mathematics examination "Nilai Ebtanas Murni" (NEM) in every State Junior High School needs to be carried out thoroughly in order to improve the quality of education. This study uses spatial analysis to evaluate the curriculum and determine the development…

What would it look like to engage in more humanizing assessment practices, practices that support the positive development of students' identity, agency, and belonging? In a Southern California school district, a group of teachers have been working toward doing exactly that. One of the first things the teachers did was to recognize that the…

In this research, the level of acquiring analytical thinking skills in the secondary school mathematics curriculum was examined according to the opinions and experiences of the teachers. The research was carried out by the phenomenology pattern, one of the qualitative research designs. The research was performed with the voluntary participation of…

In this case study, we investigate one teacher's implementation of DNR-based combinatorics curriculum in their high school discrete mathematics class. By examining the teacher's practices in whole-class discussions of two counting problems, we study how they advanced a variety of ways of thinking to support the development of a set-oriented way of…

Recursive reasoning is a powerful tool used extensively in problem solving. For us, recursive reasoning includes iteration, sequences, difference equations, discrete dynamical systems, pattern identification, and mathematical induction; all of these can represent how things change, but in discrete jumps. Given the school mathematics curriculum's…

This paper presents data from the first of three iterations of teaching experiments conducted with secondary teachers. The purpose of the experiments was to investigate how teachers' combinatorial reasoning could support their development of algebraic structure, specifically structural relationships between the roots and coefficients of…

The Louisiana Department of Education (LDOE) develops all mathematic standards and curricula in Louisiana. Once approved, these items become the officially mandated curricula that each school must teach. LDOE is also responsible for the flow down of the official curricula to each school system, plus providing the appropriate amount of training to…

Policy efforts in mathematics have focused on increasing teachers' mathematics content knowledge (MCK), with the goal of increasing teacher quality and in turn increasing student mathematics learning. An alternative approach to increasing student mathematics achievement is to investigate curricula that can be effectively used by teachers with a…

Mathematical modelling has garnered national and international interest due to its importance. Mathematical modelling can develop students' mathematical understandings, teamwork and communication practices. The ability for teachers to select appropriate mathematical modelling tasks is important to ensure the benefits listed for students are…

This qualitative case study explored an elementary foundations mathematics course and the mathematics vocabulary elementary pre-service teachers (PSTs) encounter at various stages in their preparation as mediated by curriculum, standards, and assessment materials. Guided by the theoretical lens of a constructivism-informed conceptual framework,…

The research reported in this paper analyses teaching dilemmas experienced by four in-service teachers in the context of a reform-oriented teaching approach for primary mathematics called Developmental Education in Mathematics (DEM). The findings exemplify three teaching dilemmas: Whether to tell students how to solve a challenging task; what to…

This study investigated how Japanese curricula represent functional relationships through the lenses of quantitative and covariational reasoning. Utilizing both macro and micro textbook analyses, we examined the tasks, questions, and representations in the Japanese elementary and lower secondary course of study, teachers' guide, and textbooks.…
