The importance of computational thinking skills in mathematics has been recognized in educational research for a long time. More recently, this recognition has materialized in formal international recommendations (e.g., by PISA's 2022 Mathematics Framework) and in national or provincial curricular reforms (e.g., in France, Sweden, and Canada) that…

The purpose of this study is to investigate students' mental models of the marine environment and to further examine how these models are related to their perceptions of marine problems. One hundred twenty-eight ninth grade students from a large harbor city in southern Taiwan completed a survey including a drawing activity and a set of two-tier…

Active teachers noted persistent problems in their classrooms, including low levels of student engagement and gaps in students' use of evidence in forming arguments. Earth Science students provided written responses to two questions using the previously implemented Claim, Evidence, Reasoning (CER) framework. The first question was answered without…

This paper reports results from a six-state study of 62 USA social studies classrooms. We examined the extent to which intellectually challenging authentic pedagogy was present in study classrooms, the characteristics of classroom practice at different levels of authentic pedagogy, and how those characteristics may promote or inhibit high levels…

Co-teaching, defined by Friend and Cook (2013) as substantive instruction by two or more professionals of a diverse group of learners in a shared space, has long been a key feature of middle level instruction. This article reports on a four-year formative experiment (Reinking & Bradley, 2008) intended to generate insights to guide teachers'…

While there is widespread agreement that one-size-fits-all professional development (PD) initiatives have limited potential to foster teacher learning, much existing PD is still designed without attention to teachers' motivations and needs. This paper shows that the strengths and weaknesses of middle school mathematics teachers that engage in PD…

The "Pathway to Academic Success Project" trains teachers to improve the reading and writing abilities of English learners (ELs) who have an intermediate level of English proficiency by incorporating cognitive strategies into reading and writing instruction. This What Works Clearinghouse (WWC) intervention report, part of the WWC's…

The "Pathway to Academic Success Project" trains teachers to improve the reading and writing abilities of English learners (ELs) who have an intermediate level of English proficiency by incorporating cognitive strategies into reading and writing instruction. The cognitive strategies include goal setting, tapping prior knowledge, asking…

Diagnostic assessment approaches intend to provide fine-grained reports of what students know and can do, focusing on their areas of strengths and weaknesses. However, current application of such diagnostic approaches is limited by the scoring method for item responses; important diagnostic information, such as type of errors and strategy use is…

This research examined the effectiveness of a design-based, continuous professional development (CPD) programme intended to promote teachers' self-confidence and teaching reflection skills. The CPD was associated with teacher implementation of theoretically devised, motivational, context-based, inquiry teaching modules, based on a justified…

Professional development (PD) programs often evaluate their impact on teachers' learning by assessing teachers either individually or in groups. The goal of this paper is to illustrate the variety of paths teachers might follow as a result of working in groups within online PD settings. Data are drawn from a PD program for grades 5-9 mathematics…

In scientific arguments, claims must have meaning that extends beyond the immediate circumstances of an investigation. That is, claims must be generalised in some way. Therefore, teachers facilitating classroom argumentation must be prepared to support students' efforts to construct or criticise generalised claims. However, widely used…

This paper describes the ideas that mathematics teachers (grades 5-9) have regarding mathematical models of real-world phenomena, and explores how teachers' ideas differ depending on their educational background. Participants were 56 United States in-service mathematics teachers. We analyzed teachers' written responses to three open-ended…

There are urgent calls for more studies examining the impact of Professional Development (PD) programs on teachers' instructional practices. In this study, we analyzed how grades 5-9 mathematics teachers used graphs to teach mathematics at the start and end of a PD program. This topic is relevant because while many studies have investigated…
