Describing and measuring instructional quality of mathematics lessons is a common goal amongst mathematics education researchers. Such work takes several forms such as classifying and coding instructional moves and student activity or providing high-level rubric-based scores in relation to categories. In this work, we share an innovative mixed…

The objectives of this study were (1) to develop local-based learning activities in an integrated learning unit entitled "The Legend of Phra Yuen Kantharawichai" for grade 5 students; (2) to compare the student's academic achievement with a criterion of 80%; (3) to compare the students' historical process skills with a criterion of 80%;…

Recent reforms in science education call for efforts to engage students in authentic and sustained science practices. In order to engage students in authentic science practices, students need to enact epistemic agency over the processes of inquiry in line with how knowledge is constructed and practiced in the real world. A critical research…

Purpose: This paper presented the learning process of a group of primary mathematics teachers who participated in two iterations of lesson design, enactment and reflection in a Chinese Lesson Study. Design/methodology/approach: An expansive learning theory was employed to examine the teachers' learning process in lesson study (LS) on representing…

This paper describes how fifth-grade English Learner students (ELs) in an urban school district develop the mathematics register during a problem-solving lesson. It provides examples of students' work to illustrate how they use the mathematics register to communicate their mathematical ideas orally and in writing. The teacher implemented teaching…

Self-efficacy in mathematics is related to engagement, persistence, and academic performance. Prior research focused mostly on examining changes to students' self-efficacy across large time intervals (months or years), and paid less attention to changes at the level of lesson sequences. Knowledge of how self-efficacy changes during a sequence of…

Calls for "mathematics for all" or "mathematics for social justice" bring light to the importance of equity issues within and through mathematics education. Employing the theoretical perspectives of equity and social justice for mathematics education, and the intersection of language, culture, and mathematics, this study…

Experimental evidence has shown the effect of peer-group argumentation on scientific concept development. However, questions regarding how and why it happens remain. The aim of this study is to contribute, with experimental evidence gathered in naturalistic settings (classrooms), to the understanding of the relationship between peer-group…

In this paper, we describe our learning progressions approach to early algebra research that involves the coordination of a curricular framework, an instructional sequence, written assessments, and levels of sophistication describing the development of students' thinking. We focus in particular on what we have learning through this approach about…

The study set out to discover what characterizes the meaningful learning of mathematics among low-achieving students (LAS) and to highlight the challenges their characteristics pose for scaffolding, in particular for its adaptive core: contingent teaching. The setting was an extracurricular program for teaching meaningful mathematics to LAS…
