How does one look for mathematical structure? Finding structure is a challenging yet accessible activity for all students. This article describes a lesson in which seventh graders engaged with mathematical structure. The setting was a seventh-grade prealgebra classroom in a suburban school. The classroom teacher was co-author Tatyana Finkelstein.…

Argumentation has been a prominent concern in science education research and a common goal in science curriculum in many countries over the past decade. With reference to this goal, policy documents burden responsibilities on science teachers, such as involving students in dialogues and being guides in students' spoken or written argumentation.…

Technological Pedagogical Content Knowledge (TPACK) is a model that explains how teachers use technology more effectively in the context of technological, pedagogical, and content knowledge. Teachers' TPACK competencies play great importance in this regard. Lesson study has also been playing significant roles in the development of teachers'…

This paper aims to explore how the use of lesson study approach with a constructivist framework could enhance Year 9 students' conceptions of pressure specifically on the topic of manometer reading in determining gas pressure. A diagnostic test was first administered to three Year 10 classes to help teachers identify student difficulties in…

This article presents a theoretical model of lesson study's impact on instruction, through intervening impact on teachers' knowledge, beliefs and dispositions, teachers' learning community, and curriculum. It also describes four different types of lesson study in Japan, pointing out their synergies in producing a system where local teachers…

This study examines how mathematics teaching research specialists mentor practicing teachers during post-lesson debriefs of a lesson study in China. Based on a systematic, fine-grained analysis of 107 h of videotaped mentoring meetings of 20 groups of teachers and teaching research specialists from different elementary schools, this study reveals…

Lesson study (LS) has been practiced in China as an effective way to advance teachers' professional development for decades. This study explores how LS improves teaching that promotes students' understanding. A LS group including didacticians (practice-based teaching research specialist and University-based mathematics educators) and mathematics…

An essential element in teaching children to effectively comprehend text is the use of teacher-led think-alouds. The overarching objective of this study was to explore how to better prepare early career teachers to conduct think-alouds in their classrooms. Data from 31 teachers consisted of (1) questionnaires, (2) lesson plans, (3) lesson…

Educators can take advantage of Latino English learners' linguistic backgrounds by teaching Spanish-English cognate vocabulary using the Children's Choices picture books. Cognates are words that have identical or nearly identical spellings and meanings in two languages because of their Latin and Greek origins. Students can learn to recognize…

This article analyses lesson study as a mode of professional learning, focused on the development of mathematical problem solving processes, using the lens of cultural-historical activity theory. In particular, we draw attention to two activity systems, the classroom system and the lesson-study system, and the importance of making artefacts…

Teachers have found that engaging students in justification can help students deepen and retain mathematical knowledge, gain a greater sense of ownership over the material, and improve communication and representation skills (Staples, Bartlo, and Thanheiser 2012). Student engagement in a justification activity can also lead to more equitable…

This paper explores the role that technology can play in engaging pre-service teachers with the iterative, "messy" nature of model-based inquiry. Over the course of 5 weeks, 11 pre-service teachers worked in groups to construct models of diffusion using a computational animation and simulation toolkit, and designed lesson plans for the…

To stimulate individualised learning and give students some autonomy and responsibility in relation to their own schoolwork, Norwegian teachers often use work plans as an instructional tool. A work plan is a document that describes different tasks students are supposed to complete within a certain time period, normally two to three weeks. This…

This study used a multiple-probe, multiple-baseline single-case design to investigate the efficacy of planning, and then revising strategy instruction using self-regulated strategy development on the compare-contrast writing performance of three late elementary students with language-learning disabilities. After receiving the planning instruction,…

This qualitative research study examined the extent to which novice and student teachers drew upon pre-service preparation to use scaffolding practices identified in the literature as supportive of bilingual learners' (EBs') acquisition of academic content. Data sources included videotaped class observations, lesson plans and teaching materials,…
