This study aims to analyse teachers' understanding of realistic mathematics education (RME) through a blended workshop on designing an RME-based learning trajectory. Data was collected via online pre-test and post-test, involving mathematics teachers of junior high schools in Banda Aceh, Indonesia. The tests were accompanied by interviews, chats…

The relation between reading and mathematics achievement is an active area of research, and evidence in the extant literature suggests they are closely related. However, there is a lack of understanding about how their relation develops over time. Indeed, traditional longitudinal analyses have focused on investigating each domain independently,…

In our data-driven society, it is essential for students to become statistically literate. A core domain within Statistical Literacy is Statistical Inference, the ability to draw inferences from sample data. Acquiring and applying inferences is difficult for students and, therefore, usually not included in the pre-10th-grade curriculum. However,…

Students encounter difficulties in solving areas of triangles and quadrilaterals due to a lack of conceptual understanding of the topic. The researchers have developed the following activities and the hypothetical learning trajectory (HLT) through the design research approach focusing on developing activities for students to learn the concepts…

Field supervisors are central to clinical teaching, but little is known about how their feedback informs preservice teachers' (PSTs) development. This sequential mixed methods study examines over 3,000 supervisor observation evaluations. We qualitatively code supervisor written feedback, which indicates two broad pedagogical categories and nine…

Research shows a heterogeneous picture of migration-related disparities regarding adolescents' educational trajectories at the end of lower-secondary education. Among other disparities, migrants face large disadvantages with regard to the transition to vocational education and training (VET). They are, however, also more likely to change to…

Argumentation skills are emphasized by the common core state standards (CCSS) and are viewed as essential for success in college, career, and life. Our project aims to develop formative assessment tasks measuring students' argumentative reading and writing skills. We used the framework of the "Discuss and Debate Ideas" key practice…

Studies have shown how family (typically parents) and formal institutions (specifically schools and universities) shape individuals' dispositions--or "habitus." However, other sites of academic socialisation, such as tutoring centres and coaching institutions (collectively forming a shadow education system), are seldom scrutinised for…

The aim of this article is to present a pedagogical approach for history education. This approach is called Meaningful History and it outlines the process by which upper-level secondary history students can cultivate historical consciousness. Based on the notion of learning as meaning making and historical consciousness as a disposition to engage…

In this report we show an investigation of how high-school students learn strategies to find intermediate numbers in an interval to understand the property of numerical density. Research has shown that some high-school students have difficulty in understanding this property. To mitigate this difficulty, we proposed a Hypothetical Learning…

Emergent graphical shape thinking (EGST) entails conceiving a graph as being dynamically generated via the trace of a moving point constrained by two changing quantities. As such, Paoletti et al. (2023) argue that meanings for quantities within a situation and meanings for graphical representations must be connected, or bridged, to engage in EGST.…

In this study, we explore the use of analogies with classical physics in introductory quantum physics (QP) teaching. This work is part of a larger project in which a learning sequence covering three introductory QP topics was designed, tested, and evaluated in collaboration with high school teachers and physics education researchers. Based on the…

This paper comprises the results of a design study that aims at developing a theoretically and empirically based learning trajectory on statistical inference for 9th-grade students. Based on theories of informal statistical inference, an 8-step learning trajectory was designed. The trajectory consisted of two similar four step sequences: (1)…

Computational thinking (CT) is a set of cognitive skills that every child should acquire. K-12 classrooms are expected to provide students opportunities (tasks) to think computationally. We introduce a CT competency assessment for middle school students. The assessment design process started by establishing a cognitive model of CT domain mastery,…

Background/Context: Access to rigorous courses in high school is essential for college success (ACT, 2005), but low-income students and students of color take fewer demanding courses than their white and Asian counterparts (Cowan Pitre, 2014; Theokas & Saaris, 2013). The issue of inequitable access to more advanced courses requires a deeper…
