This article presents a curricular reasoning model developed based on research conducted with middle grades teachers as they planned, taught, and reflected on a geometric transformations unit. Teachers can use the model to become aware of their own curricular reasoning to make key mathematical decisions as they plan and teach their lessons. While…

This three-day lesson plan provides students with an introduction to reading topographic maps using multiple modalities. The goal is to give students a range of opportunities using different media to increase their map-reading skills. After hands-on modeling, a summative assessment provides students with the opportunity to put their topographic…

This action research aims to develop the ability to solve mathematical problems, particularly in polygons, through open-approach learning management for sixth-grade students, with the goal of achieving an average score exceeding 70% of the total possible score. The target group consisted of eight students in the second semester of the academic…

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…

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…

Selecting and implementing a new mathematics curriculum program that is both high quality and is supported by stakeholders is a challenging endeavor. In this article, the authors share a year-long process in which a school district's (SD) elementary mathematics committee (EMC) engaged in exploring, testing, and selecting a curriculum program to…

Performing music is one of the fundamental processes of music education. A musical performance includes not only singing or playing accurate notes and rhythms but also making interpretive decisions to convey music expressively. The author researched to find out the best strategies for developing expressive performance, and then created a lesson…

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…

This case study explores the integration of language-generating artificial intelligence (LGAI) in K-12 instructional planning, focusing on a middle school science teacher's use of these tools within the Technological Pedagogical Content Knowledge (TPACK) framework. The study investigates two primary concerns: how LGAI is utilized for lesson…

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…

Mathematical concepts have been a consensus goal for decades, yet there is little consensus on what is meant by the terms "mathematical concept" and "mathematical understanding." This article attempts to discuss these terms in a way that can be of practical use to teachers. Greater clarity on "mathematical concept"…

"Kyouzaikenkyuu" (translated as "instructional materials research") is said to be a crucial part of successful Japanese lesson study. "Kyouzaikenkyuu" is described as the planning portion of the research lesson during lesson study. "Kyouzaikenkyuu" is also said to be done on a daily basis by Japanese…

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…

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'…
