Researchers have established that solid argumentation is essential for developing, establishing and communicating mathematical knowledge, which attracted substantial attention from researchers, but few have simultaneously investigated the argumentation performance of sixth-graders and their teacher's potential influence in Chinese rural…

The COVID-19 pandemic has significantly altered the organization and scheduling of high schools in Spain. Due to pandemic restrictions, most students from grades 9 to 11 come to class only on alternate days. In this situation, e-learning and distance learning have gained prominence as necessary methods of instruction. In this study 68 students…

In our pursuit to broaden and deepen understandings of what it means to engage in an assessment activity, we explored the designing and implementing of a geometry performance task as an instantiation of authentic assessment to assess elementary school students' mathematics learning. Using participatory action research, we incorporated a…

The issue of higher-order thinking skills in Indonesia began to be raised in line with the changing goals of mathematics learning. The efforts have been made to be able to produce improved thinking skills, one of which is the PINTER model. This study aimed to see if there are any differences in higher-order thinking skills and mathematical…

This study used hierarchical linear modeling to examine the relationship between an internet-based mathematics formative assessment and data from a mathematics summative assessment for primary grade learners (ages 5-7). Results showed a positive relationship between formative assessment data related to the concepts of counting and decomposing…

The aim of this study is examining the relationship between student achievement and bringing interesting materials to the classroom in 4th grade mathematics in Saudi Arabia, Qatar, Turkey, and Singapore. This study used TIMSS 2015 data to investigate the relationship between student achievement and bringing interesting materials to the classroom…

Mathematics classrooms have a long history of what has been termed 'unidimensional' character: a proclivity for student practice routines and teachers as experts and keepers of knowledge. This study investigates affordances of student-created digital learning objects (SC-DLOs) as transformative, design-for-learning practices in the hands of…

This study used integrative data analysis (Curran & Hussong, 2009), which allows combining data from different studies, to examine the generalizability of a research-based mathematics program, schema-based instruction (SBI), with a focus on proportional reasoning. Data were pooled from existing SBI studies spanning three U.S. states in which…

The aim of this study is to put forth the opinions of mathematics teachers about distance education carried out using the Educational Informatics Network known as EBA (Egitim Bilisim Agi) which is a new practice in Turkey. In accordance with this objective, 10 Mathematics teachers who work in institutions affiliated to Ministry of National…

A few case studies have suggested students' struggles with the "temporal order" of epsilon and delta in the formal limit definition. This study problematizes this hypothesis by exploring students' claims in different contexts and uncovering productive resources from students to make sense of the critical relationship between epsilon and…

The programmed instruction helps each student gain knowledge with different time or sequences, depending on available knowledge, ability, and learning speed. With this method, students can perform self-evaluation and self-regulation in learning activities. This article presents the application of the programmed instruction method in designing the…

In recent years, attention has turned to the development of evidenced-based learning progressions/trajectories as a means of identifying the likely paths learners might take in developing a deep, well-connected understanding of key aspects of mathematics. However, the extent to which this work influences what happens in mathematics classrooms…

This study focused on statistical investigation tasks designed by preservice teachers. Participants designed a statistical investigation task as a culminating summative assessment after completing modules on teaching and learning statistics. Our study examined the designed tasks to identify their strengths as well as areas of needed improvement.…

The two studies examined in this paper compare the different mathematical opportunities provided in preschool classrooms in China, Japan, and the United States, with an emphasis on mathematical-themed books in classroom libraries. Study one presents the results of an online survey to examining the content of preschool classroom libraries in China…

Too often, high school algebra students encounter topics in a discrete, disconnected fashion. In the authors' first years of teaching, they found students to be adept at solving problems they were currently studying; for instance, they could solve quadratics during a quadratics unit. Too often, however, students struggled with that same content…
