In the mid-1960s, educational lawmakers began passing and implementing plans to raise the achievement of all students across the United States. In these early years of education mandates, the federal government became more involved in public education. Education lawmakers began to focus on struggling learners and how teachers could support those…

It is seen that there are few studies on the role of the knowledgeable other when the literature on Lesson Study [LS] is examined. However, for LS to be better understood and applied in different cultures, the role of the knowledgeable other in LS process should be clarified. This study aimed to determine the role of the researcher as the…

Mathematics education researchers suggest that providing the opportunity to struggle with important mathematics (SOS) is a necessary component of lessons in order for students to conceptually understand mathematics. There are many ways to promote and support SOS, yet very few lessons demonstrate SOS in today's middle grades classrooms. This study…

This study aims to identify how mathematics teachers understand whole-class discussions and to know the influence of lesson study on the way they orchestrate these discussions. This is a qualitative study, conducted with two groups of middle school teachers. We analyze data concerning three teachers, Patrícia, Marta, and Diana, collected through…

The paper evaluates math performance at four high-need middle schools during a four-year intervention, which was designed to help math teachers diagnose students' areas of need and to design lesson plans responsive to those needs. Before the intervention began, the researchers pre-selected four comparison schools by matching based on achievement…

This convergent mixed methods study sought to explore the effects of engineering design challenges (EDCs) on middle school students' achievement. Data was collected from four middle schools from an urban school district in Maryland. Two of these, Group A, included teachers with experience with EDC design and implementation; the other two schools,…

The aim of the study was to test the effect of teachers' professional development upon students' mathematics academic achievement levels with the help of lesson study. In this manner, the study aimed at increasing students' mathematics learning levels via lesson study. Action research was used as research method in the study. The sample of the…

Global climate change is one of the most significant challenges of the twenty first century, requiring its integration into K-12 science education curricula to foster informed and climate-literate citizens. However, challenges remain in effectively teaching climate change, including a lack of instructional materials and a reliance on traditional…

Purpose: This study aimed to determine the expectations of students from mathematics teachers in the planning phase of lesson study (LS) in mathematics classrooms. Design/methodology/approach: This study reported only a part of large-scale action research. The participants were Grade 8 students selected by the convenience sampling method. The data…

The vocational experiences and skills of young adolescents could be infused into formal education by identifying career competencies to be taught within the academic curriculum. Such curriculum practices that embed educational and career pathways must also include the perspectives of students and the community, particularly those from marginalised…

Teachers who know what, how and why to teach are essential for successful student learning. However, many preservice teachers (PSTs) lack teaching experience and the ability to integrate theory and practice. To help bridge this gap, this study employed a learning-by-design project approach in which 22 Korean PSTs developed lesson plans for middle…

This research examined how pre-service mathematics teachers (PMTs) plan to support argumentation in their lessons about the hierarchical relationships among the quadrilaterals and what they notice during planning. The participants of this case study were eight pre-service middle-school mathematics teachers. Data consisted of the PMTs'…

This study explored four middle-school mathematics teachers' provision of non-examples and instructional explanations in teaching rational numbers to seventh-grade students. The data sources were 8 lesson hours of observations conducted in four different classrooms. Yin's [(2018). "Case study research and applications: Design and…

Declining national assessment scores and continuous critiques of Common Core curricula have presented persistent challenges for stakeholders within the American education system. This study was an investigation of the existence of parallelism in five commonly used Common Core middle school mathematics curricula. An embedded mixed methods research…

There has been growing evidence suggesting that collaboration between content teachers and English as a second language (ESL) teachers is crucial for multilingual learners' (MLLs) equitable learning experiences. What is lacking is more nuanced analyses of teacher collaboration in the classroom context. This article reports on the findings of a…
